Editor’s message Composting Cape Town Sun City and barley tours

Recently I was rather delighted when one Saturday (yes Saturday!) the City delivered one of their composters to our house for our use, with some how-to literature. Hats off to the City of Cape Town for this brilliant programme that will encourage home composting and reduce waste in people’s bins. Even better, it will make suburban gardens grow beautifully and is generally just all-round good for the environment – you just “feed and stir” (as the sticker on the composter reminds you). For good measure I also use Margaret Roberts’ Compost Maker, which speeds up the processes. We were thrilled to learn about how Sun City’s incredible landscape and wonderful gardens' landscape team make their own compost onsite from green waste. We feel the story of the famous luxury resort’s water wise ways – that

few months ago I applied for a free composter from the City of Cape Town, after reading about the City’s new composting programme on our local library’s notice board.

In typically Cape Town fashion – where “we do” recycling and composting – the offer had naturally captured a lot of Capetonians' imaginations. Indeed, the email receiving the applications for the gratis composters reported “mailbox full” a couple of minutes after the offer opened. I could just picture gazillions of people in Cape Town gleefully applying for a “home composting container”. I valiantly resubmitted with all the necessary paperwork.

We know you will enjoy this read a lot! SABI magazine was lucky to be invited on a media tour of the 2016 Barley Harvest in the Overberg in the Western Cape, by South African Breweries (SAB). Learning about the cultivation, growth, harvesting and use of barley was interesting. SAB has won wide acclaim for its highly effective precision irrigation’s water and energy conservation successes in the Northern Cape. Johan Barnard visited Angola recently on an irrigation fact-finding mission, and his story on the state of irrigation in Angola is a great read and is highly thought-provoking. Don’t miss this read about that essentially highlights the potential, challenges and incredible creativity on our African continent.

President’s Message

All in a day’s work Rain forests, palaces and barley


n the early eighties, as a young irrigation technician with Stewarts and Lloyds, I involved myself with the establishment of the gardens at Sun City, and especially the “rain forest” for the Palace of the Lost City”.

For me as a nature lover, one of the most incredible “by products” of the creation of a rain forest in an arid environment poles apart from the real thing, was the arrival within a short time, of a number of bird species that are normally only found within a rain forest. The power of nature indeed. In this issue, we have a feature on Sun City,

whose gardens recently won a Water Wise award. Another of SABI’S wise older men (not yet at the “bullet” stage), past president and SABI Trainer Johan Barnard, shares the irrigation potential of Angola, and their novel recycling of old dripper pipes.

With ABInbev’s purchase of SABreweries a fait accompli, the feature on the barley harvest in the Caledon area, and their sustainable farming ventures has particular relevance.

Tony Ewels– President

These are just a few of the great reads and information waiting for you in this issue of SABI Magazine. Enjoy.




Drip irrigation

Essential for Angola? by Johan Barnard

Vast tracts of arable land?


n a recent visit to Angola, we went to investigate how SABI may be of assistance to subsistence farming in a country that was ravaged by civil war for many years.

Poverty, drought, lack of resources and infrastructure are but some of the challenges facing the southern parts of Angola. Many tourists travel the asphalt roads to Luanda and do not experience the beauty of a country with so many diverse cultures. We travelled the less frequently used roads. We entered Angola at the Ruacana border post and travelled in a northerly direction going through the towns of Chitado and Otchinjao, before joining the tar road at Cahama on our way to Lobungo and the town of Namibe, on the West coast of Angola. From there we travelled up the coast to Lucira before we had to turn back for home due to time constraints. The “Angola taxi”, which is a road going motorbike, is extensively used for off-road purposes. This mode of transport is the only means for the local population to get around in an area where the roads could do with a bit of TLC. We had to help two gentlemen who succumbed to the treacherous conditions, when they made hard contact with Mother Earth. The driver of the stricken bike nevertheless came scooting past us with the front tyre flat and mudguard flapping in all directions only to finally grind to a halt 2 km further down the road. Needless to say he also had to take a lift with us to the nearest town.


Hand operated borehole pump

Borehole pumps Our first contact with irrigation was with a hand operated borehole pump. A chain secures the hand wheel, to prevent unauthorized use. Children played on this locked “time machine” and damaged the shaft that connects the hand operated mechanism with the rods going down the borehole. We brought it back to Namibia to be fixed and hope to soon have it replaced.

start sowing the maize seed in the riverbed after all the runoff has subsided. The sowing starts in the upper estuaries of the river and they only plant 5 rows at a time. The rows are 50 to 80m in length. Two weeks later they move down the river and plant the next 5 rows. This pattern is continuous until they reach the dam which was built in the river to supply water to the road construction efforts. In amongst the maize, they also plant tomatoes, beans and pumpkins. As the subterranean water diminishes, harvesting starts. Perfect timing, all supplied by nature. Here is no lack of innovation. In the dam they harvest the reeds which have a spongy structure. It is left to dry and then they weave “mattresses”. This looks like a carpet but due to the material’s fibrous construction, actually acts as a mattress.

Expert crafters When asked about their expert crafting skills, their reply was that they inherited this from their ancestors. It is also evident that the Portuguese must have played a huge role in this part of the world. After all, this used to be a Portuguese colony. The resilience of the Africa’s people never ceases to amaze. Westerners would find it extremely difficult to survive in these harsh conditions. A beautiful main road is under construction from Bentiaba to Benguela, with semi completed bridges along the way. But, the drop in oil prices has left this country cash-strapped and this road uncompleted. Travelling next to the uncompleted road also has its challenges – a 4-wheel drive is a necessity.

Our second contact with irrigation was when we visited a maize field just outside Lucira. It was situated in the middle of a river bed. We were to receive a pleasant surprise. When the rain season ends, which is normally around end of April, the local inhabitants


Lady lying on a mattress creatively made from reeds


Maize field outside Lucira On our way to look for a place to camp for the night, next to the sea, we took a drive down a side road at Carunjamba. This is also the name of the river and the heart-beat of this village. It was unbelievable to see so many tomatoes grown in such a small area. We were pretty sure that the whole of Angola is supplied with tomatoes from this village!

Tomatoes under drip What is amazing, though, is that all the tomatoes are grown under drip irrigation. Each little plot has its own petrol engine driven pump. The mainline consists of Layflat hose feeding into PVC submains, onto which the dripper-lines are connected. What is absolutely astonishing is that there are no filters to be seen anywhere! It later became clear that miracles are only miracles after the truth

has been discovered. On our drive towards the ocean, we saw that fences are created with old dripper pipes. The people mastered this into a craft by weaving the pipes into a pattern and also used them to cover their shacks. We have never seen so many secondhand dripper pipes recycled as fences and walls. Obviously, someone is selling massive amounts of drip irrigation in that area but, in a country where cash has become a scarce commodity, it is actually a disgrace that these people are being exploited by unscrupulous retailers. If the living conditions of the people from the Carunjamba village could only be improved by 10%, the people could also become affluent and contribute more to the country’s GDP. On our way back to Namibia via Calueque and Ruacana, we stumbled across a large open

Vast tracts of arable land?

stretch of land with everything cleared to bare land. To our surprise, 17 centre pivots were erected on this land but no main pipelines were laid. The area covers about 1000 ha and apparently 3 Portuguese brothers were granted permission to farm this area next to the KunenĂŠ River. A wide main road has also been constructed running through the middle of this vast piece of arable land.

Vast opportunities Angola has vast irrigation opportunities. However, vast knowledge of the area, cultures and government requirements is absolutely essential. During our travelling preparations, it became evident that accessing Angola is not plain sailing. It took us a few months to get everything in order. It is also best to travel with well experienced friends who know all the pitfalls. I had to drive one

of the vehicles. As Angola was formerly a Portuguese colony, you drive on the right hand side of the road. You are not allowed to drive with short pants either. I would love to help the people from Angola to enhance and escalate their skills in irrigation but am fully aware that thorough research is required to be of any assistance. Appropriate research is required before irrigation courses and skills can be furthermore presented.

Based in the Western Cape, Johan Barnard is a past SABI President and a SABI Training lecturer, with a special interest in youth upliftment and the development of agriculture in Africa.

Africa Green Revolution goes big -

More than


$30 billion

pledged to boost Africa’s agriculture in next decade


t was a blockbuster moment for African agriculture as African leaders, businesses Commitments and major development partners pledged more than US $30 billion dollars in from champions of investments to increase production, income and employment for smallholder African agriculture farmers and local African agriculture businesses over the next ten years. These collective pledges at the African Green Revolution Forum (AGRF) are • USAID launched a global report believed to represent the largest package of financial commitments to the African entitled “A Food-Secure 2030”. agricultural sector to date, backed by the broadest coalitions ever assembled in support of food production on the continent. • US $24 billion from the African

The commitments were made at the official opening of the sixth African Green Revolution Forum (AGRF) that has attracted more than 1,500 influential figures from 40 countries for three days of brokering new agricultural initiatives.

across Africa to step-up and invest aggressively over the next five years in agriculture-related endeavors.

The historic investments represent just the first wave of support for the new “Seize the Moment” campaign, one backed by the African Union Commission, the New Partnership for Africa’s Development (NEPAD), the African Development Bank (AfDB), the Alliance for a Green Revolution in Africa (AGRA), key NGOs, companies and donor countries.

Gayle Smith, Administrator of the United States Agency for International Development (USAID), set the tone for the day with a call for investors and donors to be bold and do their part to achieve “A Food-Secure 2030”. The US government already has invested more than $6.6 billion in global food security and nutrition efforts through its Feed the Future initiative. This commitment is now locked in for the long-term following approval in July of the bipartisan Global Food Security Act legislation. Smith noted that the initiative “signals the US government’s enduring commitment to global food security and nutrition and is the largest development authorization the US Congress has made in a decade.”

While African agriculture has seen significant progress in the last ten years, the “Seize the Moment” campaign is a frank acknowledgment that much more is needed for African countries to achieve inclusive economic development—and ultimately realize the international community’s Sustainable Development Goals (SDGs). The campaign is a decisive push for the political, policy, and financial commitments essential to transforming Africa’s agricultural sector. The goal: a new era of business opportunities for the 70 percent of the African population that depend on farming for food and income, yet too often face poverty and poor nutrition. Joined by President Paul Kagame of Rwanda, Kenya’s President, His Excellency Uhuru Kenyatta, officially opened AGRF 2016 by laying out a bold vision for how agriculture transformation should play out in Kenya and across Africa. Committing himself to deliver on both the political and policy agenda, President Kenyatta announced his government will invest US $200 million so at least 150,000 young farmers and young agriculture entrepreneurs can gain access to markets, finance, and insurance. He then called on his fellow heads of state



Development Bank (AfDB) over the next ten years.

• Support from the Bill & Melinda Gates Foundation to contribute at least US $5 billion to African development over the next five years.

• US $180 million in additional commitments from The Rockefeller Foundation. •

US $350 million from Kenya Commercial Bank Group (KCB) to finance agriculture business opportunities that could reach some two million smallholder farmers.

A commitment by the World Food Programme (WFP) to purchasing at least US $120 million of its agricultural products each year from smallholder farmers through a partnership called the Patient Procurement Platform.

• US $150 million over the next five years from OCP Africa to support local fertilizer distribution, storage and blending in Africa.

President Kenyatta, as Chair of the African Peer Review Mechanism concluded the ceremony by calling for a continental scorecard that will measure and track the commitments to agriculture transformation and ensure they translate into action.

• Over $US 3 billion to African agriculture over the next six years from the International Fund for Agricultural Development (IFAD); • Yara International ASA (Yara) pledged to continue with significant investments that can link smallholder farmers to lucrative value chains.

Water Wise

Winning water wise ways…

At Sun City’s luxuriously African landscape and gardens by Carol Posthumus Photos courtesy Sun International.


or anyone who has visited Sun City, the acclaimed Patrick Watsondesigned gardens are, indeed, inspiring. The glamorous African landscape has become rather famed as Sun City’s iconic landscape has provided sets for numerous movies – ranging from Blended to Dr Bones.

It’s not surprising that for many avid gardeners, the Gardens of Sun City are an essential excursion– after all the luxury resort of 555 hectares in the North West province, located between the

Elands River and the Pilanesberg, boasts a landscape with no less than 18 different forest types, which comprise the “look and feel” of Sun City. For Sun City, Life Landscapes and the Real Green Joint Venture recently received the accolade of the Rand Water Trophy for the Best Water Wise Entry at the SALI (South African Landscape Institute) Awards.



Notably, within the glamorous and soulful African gardens of Sun City, new ventures reflect Eco awareness and are great attractions for the Eco Tourist. There is a Sun City Herb Garden of 1500m² for growing use only for chefs and guests; an Animal Rehabilitation Centre, which is part of a feral cat project and an Onsite Sod/Turf Farm of 3500m². Life Landscapes has a fully functional compost facility onsite, for green waste. The waste gets sorted and then divided into different sections, each grouped for their specific use, including: chipping for mulch; green waste with mix chippings for compost, non-compostable waste (plastic etc); firewood and palm fronds. The team doesn’t bring extra compost in from exterior sources,

as it is all produced on site. They recently started a worm farm for vermicomposting. Life Landscapes’ General Manager Iwan Bronkhorst says that in this incredibly vast and interesting landscape, irrigation water management receives the highest priority in the Landscape Maintenance Function. Guests and touring gardeners to Sun City can definitely be inspired about water management and water wise garden by a visit. He comments: “Water conservation is only one aspect of a fully integrated, environmentally sustainable maintenance management system that is in place at Sun City. Our on-site employees are always available to give guests more information or even a little tour of the world class gardens.”

Water Wise Life Landscapes has an excellent team of 147 people at Sun City on a permanent basis, who are “fully empowered to achieve their agreed KPIs”. Notably, standards need to be highly exacting and rigorous in landscape environments. As Bronkhorst emphasises: “You can create the most amazing landscape in the world but if it is not properly maintained it is nothing!” “Landscape technicians receive intensive mentoring, coaching and training from the supervisory staff in order to become competent in the skills required to maintain this complex landscape. As GM it is my task to be tough on standards and soft on people. Landscape maintenance is all about routines and attention to detail.”

Water management The Life Landscape’s team delivers Award-winning comprehensive water management here at Sun City which incudes:

ff A highly efficient central control system ff This enables changes to the watering programs to be made in response to the prevailing conditions ff Measurement of water applied ff Every litre of irrigation water applied is metered, measured and recorded on a daily basis ff Water budgeting ff Water budgets are created in line with the supply from the client and local authority. Usage is constantly monitored against these budgets ff Strategic plan to cater for water shortages ff The highest value plantings e.g. rain forest, high profile public areas and special plants receive priority water allocations while water allocations on low value areas - such as lawns are reduced. ff Intensive maintenance of the system

ff Dedicated irrigation repair and maintenance teams work constantly to keep the system in good working order. ff Water wise horticultural practices ff Mulching, water scheduling etc. ff Green Waste Management ff All green waste generated from the landscape is processed into various organic products for use throughout the complex.

Natural beauty The Gardens of Sun City were developed in the 80s – when, one would guess, water conservation wasn’t as top-ofmind as presently. Bronkhorst says, however, that the Gardens of Sun City, from drawing board stages, were envisaged by their famed designer as being natural and self-generating. Today the Gardens of Sun City proudly incorporate an intense focus on responsible water management in a water scarce area. For the landscape teams at glamorous resorts such as Sun City there is a complex balance maintained between the high standards required by hotel managers and the intent of the design, in Sun City’s case an ecological, natural intent. Elaborates Bronkhorst: “Landscape designer, Patrick Watson, always saw the Gardens of Sun City being composed of natural afforestation than a contrived exotic design. It was his intention that the natural plantings would ultimately be able to survive with minimal supplementary irrigation. “As the gardens mature less water is required to sustain the landscape. This does not mean that the gardens never go into stress, but with good management of supplemental irrigation the gardens will not die.” There are several water sources at Sun City, with water re-use also featuring. .........continued on page 11

Water Wise

At Sun City, potable water is used for most of the landscapes and gardens. The recycled effluent is pumped up to the complex for priority use on the two golf courses. The Vacation Club adjacent to the Lost City Dam is irrigated with grey water. The water meets all the statutory requirements for use in public areas. There are no boreholes on site due to very poor underground sources.

Irrigation For this complex environment, the irrigation systems in the Gardens of Sun City and landscapes focus on optimum irrigation and water conservation, and include: Decoded management system - Decoder systems differ from “conventional” wiring because they allow control of many valves over very long distances,

with a corresponding savings in wire and labour. Automated irrigation system - An automated irrigation system refers to the operation of the system with none or just a minimum of manual intervention beside the surveillance. Manual watering Bronkhorst explains to us further: “Most of the systems are installed with rain sensors or moisture probes. This is to ensure optimum management of the system and the reduction of water usage.”

Overall, for the future, the Philosophy of the Gardens of Sun City is to allow the gardens to evolve over time, to reach a stage of natural balance. Bronkhorst says: “In this evolution, plants self-seed, tree canopies shade out lower levels which then require ground plants and vistas need to be kept open for guests to enjoy the gardens.

“The Gardens of Sun City will continue to evolve and it is important to ensure that maintenance practices compliment this evolution.” And long may Gardens evolve!



He says that the resort is moving away from the conventional systems – and in the future they will ensure that the whole of the resort is on the decoder system, linked to an IQ system which can be managed from the host cloud.

Experience Africa’s beauty The landscape of Sun City is • quintessentially African – complex, • creative, beautiful and mystical all at once. • Iwan Bronkhorst, General Manager Life Landscapes says that there are many different elements that add to the complexity and experience of the Sun City landscape.

These include: •

Wildly manicured forests

Lush Green lawns and trees

Pockets of Disney Standard Landscaping at the Entrance Gate, Guest Entrances, etc.

Interesting Plants and Detail e.g. baobabs, orchids, birds, fish and small animals.

“The main element defining this African Landscape is the choice of plants and plant material. It makes no sense to market an African Experience and deliver a Suburban product! “The plants do not necessarily need to come from Africa, but they must be plants that have occurred in the Landscapes of Africa and have an African feel. They are definitely not plants that originate in Europe and are found in the formal gardens and suburban gardens in the larger cities in South Africa.” Most (71%) of the soils in the North West – where the Gardens of Sun City are located – are within the Savanna Biome, while the remainder falls within the Grassland Biome.

The climate of the Province is characterised by well-defined seasons with hot summers and cool sunny winters. The predominant soil characteristics are red-yellow soils (low clay) particularly in the western parts of the province, followed by ideal crop production soils and predominantly shallow and rocky forms. Says Bronkhorst: “At Sun City, our soil is healthy and rich in organic matter, has the right balance of plant nutrients, diversity of beneficial soil micro-organisms and is well aerated and moist. Our organic matter in the soil retains water and nutrients for slow release to plants and provides good soil structure for root penetration. SABI | OCTOBER/NOVEMBER 2016

Many governments and stock exchanges require businesses to provide some level of sustainability reporting. This has become important because of growing social and environmental injustices, highprofile corporate scandals and the global financial crisis. Sustainability reporting is important because poor disclosure can lead to a decline in investments for a country. Establishing a suitable sustainability reporting framework is therefore important. South Africa is one of only a few emerging-market economies showing a significant increase in sustainability reporting. It is also the only one in Africa. Companies listed on the Johannesburg Stock Exchange have to integrate sustainability reporting with financial

 021 851 2451



reporting. If they don’t they have to explain why they’re not complying. But more needs to be done if sustainability reporting is to maintain its integrity and value. It needs to be critically assessed against international standards. We did research on the reporting of 100 companies listed on the Johannesburg Stock Exchange. We found that the use of standards and indicators was low in the real estate and consumer services industries. Other industries fared better. Companies with international status showed a stronger tendency to use international standards. They used local requirements to a lesser extent. Based on the results we developed a framework that companies can use to improve their sustainability reporting. The results are expected to be published soon.


Sustainability standards Plethora of standards and indicators There are various sustainability reporting standards and indicators. There are 17 reporting standards internationally. In addition, there are 10 categories over and above the Global Reporting Initiative’s general standard disclosure and indicators. South Africa has 12 initiatives. These are made up of mandatory requirements, voluntary guidance and initiatives put in place by the government, the local stock exchange and market regulators. These 12 initiatives include: œœ Legislation such as the Black Economic Empowerment Act and the Mineral and Petroleum Resources Development Act; œœ Voluntary guidance. This is covered by the King Code and the Johannesburg Stock Exchange’s Social Responsibility Investment Index; and œœ Other initiatives such as state-owned enterprise shareholder compacts.

Some international standards focus on policy. There are others that focus on management and others on reporting standards. The key ones include: œœ The United Nations Global Compact. and Organisation for Economic Cooperation and Development guidelines; œœ The International Labour Organisation and United Nations guiding principles on business and human rights; and œœ The Global Reporting Initiative. œœ The Global Reporting Initiative gives guidance on what and how to report. There are no binding requirements. It is meant to be used as a reporting standard alongside others. The initiative groups indicators along the following lines: œœ General standard disclosure. This includes governance, stakeholder engagement and ethics; œœ Economic, environmental and societal indicators; and

œœ Interlinked issues that address tensions between the three pillars of traditional triple bottom line reporting. This covers planet, people and prosperity.

New framework Our framework used the South African initiatives. We incorporated these with the international standards and the Global Reporting Initiative guidelines. We also included 10 categories of integrated indicators. These aim to address tensions between the three pillars of the traditional triple bottom line approach. An integrated approach provides a more coherent picture of business sustainability. Based on this framework our analysis of South Africa’s top 100 listed companies showed that they were using: œœ Eleven of the 12 South African requirements and initiatives. The state-owned enterprise shareholder compact was the only local initiative not used. œœ Only three integrated indicators.

œœ Fourteen of the 17 international standards. The companies weren’t using the Core Labour Standard, Social Accountability 8000 standard and the Fair Labour Association standard. Overall, our research showed that South African companies generally aren’t using the integrated indicators. Rather, their focus is on the triple bottom line concept. This means that the more challenging aspects of sustainability are neglected. South African companies should move from adopting low-level compliance and conformance indicators to using more complex integrated indicators. In other words, they need to move from weak sustainability to strong sustainability. Our proposed framework can provide business managers with a guide to comprehensive reporting on sustainability performance. It can also help strengthen a business’s commitment to sustainability.

Water measurement tool for hotels

(c) 2016 Hilton Hotels & Resorts".


ighteen global hotel groups including Accor, Carlson Rezidor, Diamond Resorts, Fairmont Raffles Hotels International, Hilton Worldwide, the Hongkong & Shanghai Hotels, Hyatt Hotels & Resorts, InterContinental Hotels Group, Las Vegas Sands Corporation, Mandarin Oriental Hotel Group, Marriott International, MGM Hotels & Resorts, NH Hotel Group, Soneva, Starwood Hotels & Resorts, Taj Hotels, Resorts & Palaces, Whitbread, and Wyndham Worldwide Resorts have worked together to create the industry’s first co-ordinated and consistent water measurement tool. HWMI is the result of 18 months’ work to develop a free methodology and calculation tool which will enable hotel companies and individual properties to measure and report on water consumption in a consistent way. ITP member companies have collaborated to develop the methodology, working with KPMG as technical consultants and with feedback from a stakeholder steering group of global experts, including the Stockholm International Water Institute (SIWI), Water Footprint Network, CDP and CEO Water Mandate. Fran Hughes, director of ITP said, “The hotel industry identified water as an issue it urgently wanted to

address, and whilst many hotels are already measuring their water consumption, the use of different methods makes it impossible to benchmark. By bringing these leading companies together we have created a free tool which will ensure all hotels can measure their water use in exactly the same way.”

Measuring water Measuring water consumption is a common activity in hotels but each group has a different way to measure and may include or exclude different sources or uses of water. Building on ITP’s earlier success with the universally recognised tool for measuring the carbon footprint of a hotel room,

stay or meeting – HCMI (Hotel Carbon Measurement Initiative) – now used by over 24,000 hotels globally, HWMI will allow any hotel anywhere in the world to measure and report on the water footprint of a hotel stay or meeting / event in exactly the same way. HWMI is the industry’s response to leading stakeholder concerns that one of the most pressing global issues hotels need to address is their consumption of water, and the understanding that ‘what gets measured gets managed’. Consistent measurement is the first step necessary to enable hotels to report and benchmark - and ultimately reduce - water consumption. The methodology

and tool are free to download and use by any hotel no matter its size, type or location. ITP is keen to encourage all hotels to adopt the methodology. The success of HCMI which paved the way for carbon reporting in the Cornell Hotel Sustainability Benchmarking study, showed that consistent measuring across the sector is a crucial first step before hotels can benchmark their performance against similar hotels in similar climates. Understanding a hotel’s operation in comparison with others tends to drive improvements at a faster rate, which is vital if the industry as a whole is to drive its position as a responsible sector.

A partnership to improve water management T

he World Bank and the International Water Association (IWA) declared their intentions at World Water Week in Stockholm this year to establish a global partnership to help countries, especially the poorest, improve management of water that is pumped but then lost or unaccounted for, called non-revenue water (NRW). In developing countries, roughly 45 million cubic metres of water are lost daily with an economic value of over US$3 billion per year. Saving half of those losses


would provide enough water to serve at least 90 million people. High levels of NRW reflect huge volumes of water being lost through leaks, not being invoiced


to customers, or both. Reducing NRW can significantly improve the performance of public water utilities in developing countries. The two international organizations set out to collaborate on a joint program that aims to capture good practices in the use of performance based contracts (PBCs) to reduce NRW, raise awareness on the issue

of NRW, simplify and streamline the preparation of such contracts, and support their implementation in developing countries in the next few years. Furthermore the partnership will build the market of suppliers at the local level. The Public-Private Infrastructure Advisory Facility (PPIAF) has codeveloped the initiative.

Dams and linings

Dam linings Preserve water. Africa is a water-scarce country with limited resources. The Gundle Dam Lining Division aims S outh to preserve water by sealing dams to prevent seepage of the precious resource of water. Soil Usage: In certain circumstances, farmers

The benefits of lining a dam with Gundle Dam Liners are as follows:

are able to plant extra crops around the dam area in parts of fields that weren’t accessible previously due to the seepage causing flooding and drowning of the crops.

Long Service: Our product quality is of the highest standards: with a 10 year warranty against UV Degradation and an extensive minimum expected working capability in South African conditions for fresh water storage. Our liner does not need any servicing in its life span. This ensures a water tight seal for decades, saving you on maintenance costs and more importantly time. Holes caused by physical damage can be easily repaired by our teams.

No weed problems: There is no need to spray herbicides before the installation of our liner. No weed can grow through our product due to it blocking out all the elements needed for growth. Profit: By lining your dam, you increase your effective water usage meaning that with the water that you previously lost, bigger areas of crops can be irrigated. This is especially valuable in areas where water usage per farm is restricted.

Cost Savings: With the current electricity costs associated with the pumping of water, it has become too expensive to just let precious water seep away. The costs saved on pumping justify the cost of a liner over a period, depending on different farming conditions.

Time saving: There is no curing time or drying time when it comes to our products’ installation. Once the last seal has been welded and tested, then you can fill the dam without delay.

Prevent leaching of harmful pollutants in dams With real-time monitoring of geomembranes by Raymond Campling


ompanies involved in the handling of waste water must pay special attention to the correct containment of pollutants through suitable geomembranes that have been correctly installed, maintained and monitored.

Geomembrane quality and installation specialist, Nadia Minnaar, managing director of NGQ Consulting, explains that ever-tightening requirements for the containment and handling of waste materials requires careful management to avoid falling foul of environmental legislation and regulations. Not only are severe penalties in place to punish offenders, but may cause reputation damage that may prove to be costlier in the long run. She says mitigation of these risks has led to companies involved in the specification, construction and management of containment areas taking extra precautions to ensure that their facilities are 100% compliant and regularly monitored to ensure that the

ever-important linings remain fully functional at all times.

Specialist guidance “These companies are increasingly seeking independent professional assistance when constructing containment facilities to ensure that the total construction process is carried out in accordance with design requirements within legal and regulatory requirements. Independent or third party quality assurance and quality control has now become part of the construction process and along with that comes the ability to detect any leakage of waste or clean water from these containment areas.

“The legal and regulatory requirements of South Africa regarding the handling and containment of waste and water are very clear and the issues of mining rights, water usage, water licencing, waste control, pollution prevention and health and safety has caused companies handling waste water, as well as design engineers and construction companies to ensure compliance and put guarantees in place for clients. “This has given rise to a whole new breed of specialist consulting firms such as ours who are able to monitor, in real time, the daily installation and progress of all geomembrane materials on site through custom designed software programs. These state-of-the-art cloud based quality assurance and control programmes address every aspect as set out in international s t a n d a r d s,   S A N S   10 4 0 9 and material manufacturers installation guides,” says Nadia.

Quality counts In addition, modern day consultants can act as an independent, third party Construction Quality Assurance professional on behalf of the company, its appointed engineer or the construction contractor or installer on site. They are also able to provide independent inspections for geomembrane installation onsite during receiving, throughout field installation and during any remediation processes. “Our QA/QC services are an essential element that helps to ensure a compliant project with the correct geomembrane installation methods in place. We are also able to verify geomembrane installation procedures as well as certifying the safety, purity and integrity of installed materials. We make sure that all projectspecific requirements, CQA plan requirements, industry best practices and internal specifications are met. We also ensure compliance with current


Geomembrane specialist, Nadia Minnaar of NGQ Consulting national and international standards as well as with legal and regulatory requirements. “Third party consultants should also be technically qualified to determine lining-material compliance, lining-surface preparation, as well as ensuring installation methods are correct. Thereafter to undertake daily quality control testing and live monitoring of the installation process.

Leak detection In addition to consulting services the company is also able to undertake electrical liner integrity surveys and assessments, known as leak-location surveys or electrical-leak detection. These are post-installation quality control method for detecting leaks in installed geomembranes. This type of service is imperative for the long-term protection of groundwater and the maintenance of water resources. These state-ofthe-art electrical leak-detection survey techniques are increasingly being specified by environmental authorities, as well as site owners to either forestall future liability or as proponents of responsible environmental stewardship Nadia concludes that the services offered by NGQ Consulting are designed to ensure that projects are completed on time and within budget, as well as ensuring compliance with all statutory requirements. “In this industry the only way to mitigate risk is through a comprehensive quality management system that is transparent and allows all the participants involved in the project access to the platform.”



Meat gets a bit dear As farmers wait for greener pastures


s braai season approaches, red meat prices are expected to trend higher by at least 9 to 15 percent from now until December due to tight supply and increased demand from consumers during the festive season. Currently, red meat prices are relatively stable to strong due to tight supplies as livestock farmers hold on to stock and avoid slaughtering in the hope that pasture conditions will improve should seasonal rains materialise sooner. Paul Makube, Senior Agricultural Economist at FNB says red meat slaughtering has been substantially higher this year compared to the past three years as a result of the drought. For example, the cumulative sheep slaughter number is currently 111% and 69% higher than the 2015 and 2014 levels respectively. However, despite an increase in slaughtering, we did not experience an oversupply of meat which would have resulted in lower prices due to exports and a strong demand for our meat in the tourism sector.

Outlook “In terms of the outlook for beef, we are heading into a seasonal price increase of between R3.4 and R5.7 per kilogram (kg) for Class A beef as braai season returns. Consumers that prefer to braai lamb can expect to pay between R5.6 and R9.4 per kg more for Class A lamb over the festive period,” says Makube. Pork will also benefit from the price gain of red meat. However, there won’t be much of a price movement in poultry due to increasing imports. Despite continued pressure on disposable income, consumers would still be able to absorb a slight increase in meat prices during the festive period. While others will opt to purchase red meat in bulk to outweigh price increases. “Even during tough economic conditions, we have picked up a trend where consumers will usually cut back on luxuries and

bar °C m3/h l/s

non-essentials, but generally spend more on food and meat, during the festive season.”

Resistance However, Makube cautions that prices would have to return to normal levels in January post the festive season to avoid resistance from consumers. He says that with rain expected in the coming months, the situation should start improving for livestock farmers that have suffered financial losses as a result of the drought. Forecasts are now projecting neutral conditions for the 2016/17 season, meaning that we should expect normal, instead of above normal rainfall as had been previously estimated. According to Makube, this is good news as the sector will not have to worry about possible damage resulting from floods, torrential rains and heavy winds, often associated with a strong La Nina that was predicted earlier during the past few months. The expected rainfall should be sufficient for herd-rebuilding to begin, further helping livestock farmers to reduce costs in the long-term. “By mid-2017, we should see a moderation in grain prices which will lower animal feed costs, resulting in improved margins and profitability levels for farmers that are currently facing losses from the recent drought,” concludes Makube.

Sustainability, empowerment Beer & food pairings…

All aboard for SAB’s barley harvest tour by Carol Posthumus Photos courtesy: SA Breweries


outh African Breweries (SAB) recently hosted its first SAB Barley Harvest Tour, which started in the green barley fields of Caledon and concluded at SAB’s Newlands Brewery in Cape Town – taking the group on a journey from barley to beer, and everything in between.

The tour included visits to several farms in Caledon producing barley, the South African Barley Breeding Institute (SABBI) and the SAB Maltings factory in Caledon. The Tour effectively gave insights into the barley sector and all that goes into the making of SAB’s world famous beers. Besides learning about the fine art of pairing beers with food – Castle Lite with beetroot cured rainbow trout, chocolate mousse with Chocolate Milk Stout (sold out on its first run) and so on – we also got to hear about SAB’s considerable efforts in encouraging sustainable farming practises in the sector. The beercuisine experience was hosted by congenial SAB brewer Denis da Silva, the cuisine compliments of the chef Carl from Bientang Cave

Restaurant in Hermanus. From frites (triple French friend chips and sauce) to oysters - all goes well with beer, and the experience, most agree, is even finer, when one hears that the beers are made with a myriad of effective water saving and sustainability efforts in the growth, production and brewing processes.

Winning precision irrigation Notably, SAB are putting immense effort into water saving practises and irrigation methodologies, in the wetland areas where barley is grown in the Northern Cape. In Caledon, barley is produced on dryland. Interestingly, SAB’s precision irrigation of barley has attracted

international recognition via the Mackay Awards, bringing its significant successes recognition, notes Lubbe, SAB agricultural manager, dry land, during a presentation on the tour. Frikkie elaborates that the precision irrigation of barley, part of its Prosper programme, “exceeded expectations” from year one in 2012. Prior to the introduction of precision irrigation, water consumption for barley was 544mm/ha with a yield of 6,2t/ha. After the programme was implemented water consumption dropped to 436mm/ha, with yield increasing by 28% to 8t/ha. Savings in energy also kicked in with electricity savings of 22%. The introduction of precision irrigation overall improved sustainability and saw SAB being successful in its credo of “making more beer using less water”. While travelling through the beautiful barley fields around Caledon and the Bot River,

we had numerous glimpses of SAB’s careful stewardship of the natural environment. It was to be emphasised that the Caledon area boasts a lot of natural Cape beauty - from the stunning wild flower garden in the town of Caledon to the Bot River.

Preserving conservation assets SAB – as part of its Better Barley, Better Beer programme – has for some time now encouraged local producers to work to preserve conservation assets in its barley growing areas – ranging from the re-introduction of Renosterbos (natural grazing grass) to a blue crane monitoring programme. The Better Barley, Better Beer programme, was launched in partnership with WWF to encourage and support: sustainable farming practices among barley farmers; water reduction, improved carbon

Barley and Canola


Barley Farmers footprints, soil health; clearing of alien vegetation; and protection and restoration of ecosystems. This programme is now almost at the end of its two year process. The group has also done highly constructive work into the empowerment and growth of small scale farmers in Caledon as part of its Go Farming initiative. Go Farming sees local emerging and small scale farmers working with SAB to create self-sustaining business – the farmers benefit from the growth of their own agricultural enterprises, while SAB secures the raw materials – barley and maize – needed to brew beer.

Celebrating the 2016 barley harvest season with the barley tourists were a friendly group of small scale farmers from the Caledon area, who are a part of the Go Farming initiative. They report they are experiencing tangible rewards from their hard work - happily, these days as farm owners rather than as farm workers, as they were some years ago. The small scale farmers enjoy the generous ongoing support of SAB in the form of mentoring, technical support and the provision of a market. The frustrating challenge for these farmers is in their need to buy their own land. The land is at a premium in Caledon – a

barley and canola growing area and government-owned land with limited leases does not always open the door for the farmers to the financial resources they require to expand. Notably, in excess of 250 000t (2016) of dryland barley is currently produced in the Southern Cape and a further 35000t is produced in the irrigation areas of the Northern Cape. SAB helped establish South Africa's barley growing sector in the 1970s, a strategic move to become selfsufficient in producing the key brewing ingredient, barley. In the late 70s/early 80s SABBI and SAB Maltings factory were established in the Overberg.

Close to harvest

SABBI Our group also got to pay a visit to SABBI’s-homonym SABBI (South African Barley Breeding Institute). SABBI has offices, laboratory, greenhouses and trial fields in the Caledon area, in a peaceful, pastoral setting surrounded by lush barley trial fields. SABBI barley breeder Daniel de Klerk hosted the group, and said that SABBI’s mandate is “to ensure sustainable barley production for the benefit of the producer, SAB Maltings and SAB through innovative development of new malting barley varieties.”

in South Africa.For those who like pure water, it should be noted that Newlands brewery gets its water for the brewing of its beers from the Newlands Springs. Beers originating from Newlands are brewed with this spring water.

SABBI program’s goal is to ensure barley cultivars which have superior yield potential, stability, agronomic characteristics, disease resistance, malting quality and brewing quality. The agronomic characteristics sought include yield, plumpness, straw length, ripeness, environmental sustainability and water efficiency, amongst other features.

The SAB Newlands Brewery is of historical importance, being the site of the oldest brewery in South Africa. Indeed beer brewing as a business predates the wine industry in South Africa. The original Swedish brewer who kicked off activities in the 1800s in the growing “farm” of Cape Town, would never have imagined how beer brewing would develop

Newlands Brewery has a spring water collection point, where members of the public can fill up with the spring water free of charge. The Newlands Spring water is renowned in the Cape, with people also visiting throughout history drawing on its waters for health, cultural and religious reasons. The Newlands Spring is brought to the Newlands Brewery

via a pipeline which journeys through the suburb of Newlands. The Newlands Brewery has recently opened its own custommade micro-brewery for tour, it is a multimillion rand development and sports its own pub too. At the end of the Newlands Brewery Tour a sign aptly announces: “it’s not the end, this is just the beginning”. Philosophical words from the brewers. The Newlands Brewery Tour is recommended for all beer enthusiasts visiting Cape Town, be sure to book your place when next in the Mother City!

South Africa’s first water fund -

Cape Town Water Fund


he City of Cape Town and The Nature Conservancy are looking to establish South Africa’s first water fund. The aim will be to safeguard water supplies and biodiversity, while supporting local livelihoods. The Cape Town Water Fund will be based on a proven model that builds financial and institutional mechanisms to mobilize investments in conservation of natural areas that are the sources of municipal water supply. “The City of Cape Town and The Nature Conservancy have agreed to explore the development of a local water fund to address our long-term water security concerns, while also unlocking the opportunities that this could bring for job creation and ecological infrastructure priorities,” says Counsellor Johan van der Merwe, the City of Cape Town Mayoral Committee Member for Energy, Environmental, and Spatial Planning. The City’s water supply system is inter-connected and dependent on a range of water catchment areas that lie inside and outside of the city boundaries, including 14 reservoirs

and two aquifers, the largest of which is the Atlantis Aquifer. Cape Town and these water sources sit in the heart of one of the most spectacular and unique natural areas on the continent — the Cape Floristic Kingdom— which includes Table Mountain National Park, a UNESCO World Heritage Site with an estimated 2,200 plant species of which 67 are found nowhere else on Earth. A Cape Town Water Fund would likely first focus on the Atlantis Aquifer protection zone, directing investments to conservation activities that will address the largest threat to the area’s ecological

health and aquifer recharge: the spread of invasive plants that consume more water than native plants and limit rainwater recharge. By removing invasive plants, such as various non-native Acacias, and restoring natural cover at scale, the water fund could help catalyze a significant increase in aquifer recharge and associated water availability. The Nature Conservancy is working with 60 water funds around the world, in different stages of development and operation. In 2015, the Conservancy worked with partners to launch Africa’s first water fund in Nairobi, Kenya. The fund is designed to help provide a cleaner, more reliable supply of water to over 9.3 million people and to maintain hydropower generation capacity that accounts for half of the nation’s energy supply. Conservancy scientists have found that targeted conservation actions upstream of Nairobi will generate

more than US$2 of long-term benefits for every US $1 invested. “Water is at the centre of the world’s growing demands for food, energy, and material goods, and the foundation of life,” said Colin Apse, Africa Freshwater Conservation Director, The Nature Conservancy. “Water security is a pressing challenge in Africa, and could be a limiting factor in economic advancements. As competition for finite water resources escalate, the demand for solutions that meet human needs without jeopardizing freshwater systems is urgent. Water funds open new pathways for collaboration across sectors to find solutions and for attracting the investments needed to put them into action.” “Water funds offer the promise of a transformative and lasting approach to finance and governance for critical source water protection needs in South Africa,” said Apse.

World Water Week 2016

Improving access to water project Creates new opportunities By working to decrease the daily drudgery of women and girls


n some parts of the world women and girls currently spend as many as six hours a day on unpaid care work– a vital contribution that disproportionately affects women and girls and often goes unrecognised. This can limit women and girls’ ability to take opportunities to earn a living, participate in public life, and pursue an education.

Happily, at World Water Week in Stockholm this year Unilever’s brand Surf announced a unique three-year partnership with charity group Oxfam that aims to recognise, reduce and redistribute the amount of time spent by women and girls on unpaid care work at World Water Week in Stockholm. The programme is set to start in the Philippines and Zimbabwe towards the end of the year. Crucially the collaboration will focus on improving water access and challenging social norms by encouraging the equitable distribution of unpaid work. The partnership includes providing funding to improve access to water in communities in the Philippines and Zimbabwe to help reduce the time it takes to do household chores. This will affect the lives of hundreds of thousands of people, a large proportion of whom will be women and girls. It also aims to reach millions of people globally by supporting activities to increase awareness the impact unpaid care work has on women and girls’ lives.

human rights is a vital step in ending poverty. Unpaid care work limits women’s ability to choose how they spend their time, and by tackling social norms we can make real progress. Oxfam’s expertise in providing water and women’s rights means we are in a strong position to pioneer a new and effective approach. We have already seen strong results from our pilot projects and working with Unilever will help us achieve far greater scale and impact.” Commenting on the launch, Analia Mendez, global director, social mission expertise, home Care at Unilever, said: “Responsibility for unpaid care falls on the shoulders of women and girls. In some parts of the world, women are spending most of their time on household chores – including laundry – at the expense of opportunities to learn and work.

“Collaboration is the key to making a real difference on development

“Water scarcity increases the time spent on domestic chores with girls and women going to great efforts to obtain water; in some parts of Africa and Asia, women walk on average six kilometres every day to the nearest water source.




“We have gained important insight from our portfolio of brands and products used by millions of consumers every day; Surf alone reaches 100 million households world-wide. We will use this knowledge, with Oxfam, to work to alleviate some of this load, making laundry easier and changing social norms to empower women and girls to have more choice over how they spend their time.”

x-head: Human Rights Alex Lankester, head of corporate partnerships at Oxfam, said: “We know that protecting women’s

Grondwater en die Nasionale Waterwet deur Ernst Bertram

Summary Groundwater and the National Water Act are explored in this article. The author details the background to the Act, the terminology and the common misunderstandings around groundwater. South Africa is an arid country, and the fact is that groundwater can and must be managed.

Agtergrond Die 1956-Waterwet het grondwater as privaat geklassifiseer. Die implikasie daarvan was dat die grondeienaar daarmee kon doen net wat hy/sy wou. Die werklikheid is dat, net soos oppervlakte water in ‘n dam opgevang en gestoor kan word, grondwater in ‘n waterdraer gestoor word. Alhoewel dit meestal moeilik is om die grense van ‘n spesifieke waterdraer te bepaal, is dit ‘n feit dat daar baie gebruikers van so ‘n waterdraer kan wees. Daar kan verskillende soort gebruikers wees soos byvoorbeld in die Dendron-Vivo-Blouberg waterdraersisteem, is daar beide grootskaalse (besproeiers) asook kleinskaalse (huishoudelike) gebruikers. Die gebruik, of miskien die misbruik, van gemeenskaplike hulpbronne is reeds in 1968 deur Garret Hardin (Tragedy of the Commons) verwoord. In Afrikaans word dit kortliks opgesom in die uitdrukking ‘Almal het gedink iemand sal iets doen, intussen het niemand iets gedoen nie’. Natuurlik ly almal op die ou


end daaronder. Die enigste manier om ‘n tragedie te voorkom, is om die grondwater bronne te bestuur. Die aspek van grondwaterbestuur sal later beskryf word.

Terminologie ‘n Paar terme moet op die stadium verduidelik word. ‘n Waterdraer het spesifieke grense en enige negatiewe impakte kan en sal uiteindelik almal wat afhanklik is van die waterdraer, benadeel. ‘n Voorbeeld is in die Dendron-besproeiingsgebied waar alle boorgate tydens en na die droogte van 1988/89 al dieper geboor moes word en al kleiner en meer pompe in boorgate ingebou is om die vlak van besproeiing te kon volhou. ‘n Waterdraersisteem daarenteen se grense is minder duidelik bepaalbaar en negatiewe impakte sal nie noodwendig almal benaadeel nie. Om die implikasie van ‘n waterdaer (ondergrondse dam) te verstaan is dit noodsaaklik om verkeerde persepsies oor grondwatervoorkoms en die beweging van water in ‘n waterdraer op te klaar.


Misverstande of wanpersepsies Daar bestaan glad nie ‘are’ waarin grondwater vloei nie. Die persepsie is gewoonlik dat water wat in ‘are’ in ‘n bepaalde rigting vloei vars sou wees, en waar water in ‘are’ wat in ‘n ander rigting vloei dan kwansuis brak of onbruikbaar sou wees. Die feit dat grondwater, net soos oppervlakte water a.g.v. swaartekrag vanaf ‘n hoë punt na ‘n lae punt sal vloei, bewys die teendeel. Dus is die algemene persepsie dat grondwater in verskillende rigtings in ‘n bepaalde area kan vloei onwaar. Uiteraard is die vloeitempo ondergronds baie stadiger as bo-gronds.

Waar kom grondwater vandaan? Daar is baie en wydverspreide wanpersepsies oor waar grondwater vandaan kom. ‘n Voorbeeld hiervan is die Wondergat in die ZeerustOttoshoop area wat deur die Zambezirivier gevoed word, of die Dendron besproeiingwater wat uit die Nylrivier, wat net stroomaf van Moorddrift wegraak, kom. Hierdie

persepsies maak dat grondwater as ‘n onuitputlike bron beskou word en dat die bestuur daarvan nie nodig is of nie moontlik is nie. Die werlikheid is dat grondwater deur reënval aangevul word. Aangesien die reënvalpatrone in Suid Afrika baie wisselvallig is ten opsigte van tyd en plek, is die aanvulling van die grondwaterbronne dus ook wisselvallig. Dit is bo en behalwe die feit dat die meeste waterdaers in Suid Afrika beperkte stoorvermoë het. Nog ‘n misverstand wat beklemtoon moet word is dat sterk boorgate met hoë lewerings glad nie beteken glad dat daar ‘n groot volume water in die betrokke waterdraer gestoor word nie.

Nasionale Waterwet (Wet 36 van 1998) Van die probleme wat hierbo genoem word, is deur die wetskrywers van die Nasionale Waterwet (Wet 36 van 1998) óf self ervaar óf voorsien en daarom is die wetlike status van grondwater verander om dit dieselfde as die van oppervlakte water te maak.


Die volledigheid van die watersiklus (hydrological cycle) word erken. Dus is grondwater nie ‘n aparte bron nie, maar ‘n wisselwerking tussen grondwater en oppervlakte water in beide rigtings bestaan. Dit bring mee dat grondwater nou dieselfde wetlike status as oppervlakte water geniet. Enige grondeienaar het, volgens die Nasionale Waterwet, nou slegs redelike gebruiksreg van die water wat ondergronds voorkom. Hierdie redelike gebruiksreg is in Skedule 1 van die Nasionale Waterwet vervat, naamlik veewater, water vir huishoudelike gebruik en niekomersiële tuine. Daar is geen registrasie vereistes verbonde aan hierdie gebruike nie. ‘n Tweede vlak van redelike gebruik word ‘Algemene Magtiging’ genoem. Daar is beperkings op die volume grondwater wat onder die Algemene Magtiging onttrek mag word. Die beperkings geld vir individuele kwaternêre oppervlakte water-opvanggebiede. Die wet vereis dat grondwatergebruik geregistreer moet word. Watergebruikerslisensies word vereis vir grootskaalse grondwatergebruik vir besproeiing soos byvoorbeeld in die Dendon-Vivo en Coetzerdam-Louwna areas, waar 100% van die besproeiingswater uit

grondwaterbronne kom. Om terug te keer na die Nasionale Waterwet – ‘n Belangrike dryfveer van die Nasionale Waterwet is die feit dat die Republiek van Suid Afrika ‘n waterskaars land is. Daaruit vloei die volgende wetlike verpligtinge: i) Volhoubare gebruik; ii) Doeltreffende en voordelige aanwendiging; iii) Gelykberegting in die toegang tot, en verdeling van beskikbare waterbronne. Dis bring dus, in terme van grondwater, ‘n radikale ommeswaai mee in vergekyking met die 1956-waterwet. Ongelukkig is die boodskap nie genoegsaam beklemtoon na die implementering van die Nasionale Waterwet (Wet 36 van 1998) nie en is daar baie mense wat steeds glo dat grondwater nog steeds ‘privaateiendom’ is.

Boorgate Mens kan moontlik vra wat dan van boorgate. Ons het dan altyd geglo grondwater en boorgate is sinoniem. Dit is wel so dat daar net twee maniere is hoe om grondwater uit ‘n waterdraer te bekom, dit is d.m.v. boorgate en fonteine. Die gebruik van fonteinwater is uiteraard die mees volhoubaartse gebruik van grondwater. ‘n Fontein is die ekwivalent van ‘n oorloop van

‘n dam en verminder dus nie die reserwes nie en die natuurlike waterbalans in die waterdraer word nie versteur nie. Boorgate en onttrekking uit ‘n waterdraer versteur wel hierdie balans, maar die wetskrywers was van mening dat Skedule 1 en die grondwateronttrekking onder die Algemene Magtiging nie ‘n onomkeerbare negatiewe impak sal veroorsaak nie. ‘n Vraag oor boorgate wat gereeld opduik is die of toestemming nodig is om ‘n boorgat te boor? Geen melding word in die Nasionale Waterwet (Wet 36 van 1998) van boorgate gemaak nie, dus is dit glashelder dat enige persoon ‘n boorgat op sy/haar eiendom mag sink, sonder enige toestemming. Wat wel gedoen moet word is dat die grondwatergebruik, volgens bogenoemde kategoriëe, geregistreer word.

Hartebespoortdam, hulle nie bereik nie. In ‘n ondersoek deur Vegter en Hobbs (1980) is bevind dat daar stroomop van Koedoeskop talle boorgate en sandpunte in die sandbedding van die Krokodilrivier voorkom. Hierdie onttrekkings het die sandbedding ontwater en dus het die loslatings uit die Hartebeespoortdam eers die sandbedding aangevul voortdat die rivier verder kon vloei. Daar is toe ‘n area omlyn waarbinne alle ontrekkings, hetsy direk uit die rivier of die sandbedding van die rivier via booragte en sandpunte, as oppervalkte water beskou sal word. Dieselfde klagte kom van die Nasioale Krugerwiltuin a.g.v. ekologiese loslatings uit die Blyderievierpoort-dam. Dit is duidelik dat dieselfde hier gebeur. Ongelukkig word hierdie aspek glad nie in die Nasionale Waterwet (Wet 36 van 1998) aangespreek nie.

Veduideliking van die wisselwerking tussen gronden oppervlakte water


Die grondwatergemeenskap beskou alle water wat deur middel van boorgate en of sandpunte (well points) of putte onttrek word as grondwater. Die teendeel is egter deur Vegter en Hobbs (1980) bewys. In die Krokodilrivier (wes) in die omgewing van Koedoeskop het boere gekla dat die toegekende loslatings uit die

Suid Afrika is die 30ste waterskaarste land in die wêreld. Alle water vorm deel van die watersiklus. Grondwateraanvulling word deur reënval gedryf. Deur van ‘n hele paar misverstande ontslae te raak daal die besef neer dat grondwater kan en moet bestuur word

Seasonal Climate Watch

August 2016 to January 2016 Advisory Current observations still show a neutral ENSO (El-NiĂąo Southern Oscillation) state. As indicated the previous month the development of a weak La NiĂąa, to be in effect during spring and summer, has become less likely and the persistence of the current neutral conditions may also occur, limiting its impact on Southern African rainfall. Spring rainfall is largely expected to be below-normal due to certain conditions over the Indian Ocean that may negatively impact

Recommendation moisture transport towards the African continent. Even though there are multiple indications of above-normal rainfall conditions for the summer rainfall areas in early summer, these are specifically uncertain due to the long lead time of the forecast as well as the expected weak La NiĂąa state. With regards to temperatures, all indications are that the spring and summer seasons would be warmer than normal.

As indicated last month as well - most parts of South Africa are currently still experiencing drought conditions, and the general view is that these effects may persist for some time to come even if significant rainfall occurs in summer. The prospects for rainfall during the spring and summer period is mostly unclear with only a cautious indication of a drier and warmer spring and a wetter and warmer early summer

period. We are however still in the early stages of development of the main climate drivers and their direction and strength may change leading up towards the important summer months. As always it is recommended that the medium- and shorter-range weather forecasts be monitored for the development of conditions that may alter or strengthen the expectation of the current forecast.


Minimum and Maximum Temperatures

The start of the forecasting period indicates somewhat of a mixed forecast for spring, and considering the lack of forecasting skill in this period the forecast remains uncertain. The early summer months indicates a very strong probability for above-normal rainfall for most of the country, however with insufficient supporting evidence it is unclear at this stage whether this will occur. For improved confidence in a probabilistic prediction use is made of skill scores most notably the Relative Operating Characteristic (ROC) which indicates the relative performance of the prediction system. Areas of ROC scores above 0.5 may be considered as areas of added confidence for the prediction (Figure A1).

Mostly warmer than normal temperatures are expected for South Africa in spring and early summer. There is an indication for below-normal temperatures over the western and southern coastal areas however. For improved confidence in a probabilistic prediction use is made of skill scores most notably the Relative Operating Characteristic (ROC) which indicates the ability of the forecasting system to distinguish events from non-events. As noted earlier, areas of ROC scores above 0.5 may be considered as areas of added confidence for the prediction (Figure A2).

Information supplied by South African Weather Service. Enhanced Probabilities is considered to be more than 45% probability for a specific category.

effectively flush micro irrigation laterals A step by step guide to effectively flush micro irrigation laterals - by Isobel van der Stoep INTRODUCTION Drippers and micro sprinklers are extremely sensitive to substances that can cause blockages because the flow path openings of the emitters are very small. Although signs of blockage can be observed during visual inspections, it is impossible to identify the causes of blockage on the inside of the lateral or emitter without a water analysis.

Effective preventative maintenance must be carried out to extend the life time of micro irrigation systems, and flushing of laterals is an important part of the maintenance program, regardless of the cause of potential blockage.

Blockage causes The quality of the irrigation water determines the danger of blockage. Partial blockage is as much a problem as complete blockage, since it influences the water distribution of the system negatively. It is therefore essential that the water should be analysed to identify possible causes of blockage.



This analysis must be done at the stage that the water quality is at its worst and must be compared to historical figures to monitor any variations in water quality. Table 1 indicates the physical, chemical and biological factors that can cause blockage.

How to ... Table 1: Physical, chemical and biological factors that can cause blockages (Burger et al, 2003)

Physical - Inorganic materials: Sand (50 - 250μm) Silt (2 - 50μm) Clay (<2μm) - Organic materials: Water plants Phytoplankton Algae Water animals Zooplankton Snails Bacteria (0,4-2μm) Plastic pipe cuttings Oil

Chemical - Alkaline heavy metals Cations: Calcium Magnesium Iron Manganese Anions: Carbonates Hydroxides Silicates Sulphides

A certain amount of the physical impurities in irrigation water can get through the filter and can cause blockage problems in emitters. Very fine particles will mostly remain in suspension and may possibly flocculate out at places where the flow rate is low or when the water turbulence reduces. The most likely place where sedimentation will occur is at the end of laterals. It will result in these emitters to get blocked first. Although a single particle will not necessarily cause blockage, a quantity of particles can form a clump and block emitters. Flushing of laterals is a practise that must take place regularly to prevent physical impurities from accumulating at the end of laterals. Chemical and biological impurities are usually more tenacious in their adherence to the pipes and emitters, and therefore require chemical treatment with acid, chlorine, hydrogen peroxide or a combination of these substances. However, these treatments usually result in physical impurities that then have to be removed from the laterals by means of flushing.

Flushing velocity As water moves from the beginning to the end of lateral, the flow within the lateral decreases towards the end. This also means that the flow velocity is drastically reduced towards the end, especially in the case of drip laterals where the pipe diameter stays constant over the whole length of the lateral. Dirt in suspension will collect at the end of the laterals, even if effective filtration takes place upstream. Begin



Flow direction   Dirt gathers at the end of the line High velocity

Medium velocity

Low velocity

Figure 1: Dirt collects at the end of laterals (Netafim, 2016)

For effective flushing, a flushing velocity in the lateral of between 0.4 and 0.6m/s is required. In order to sustain this velocity, the irrigation system must be able to supply adequate system flow as well as sustain the system pressure during flushing, as the opening of the lateral ends will result in a portion of the flow supplied by the pump to flow out of the system (almost similar to having a leak in the system). The table below shows the additional flow rate per lateral that will be demanded from the supply system during flushing, for typical pipe sizes used in drip irrigation systems, if a velocity of 0.5 m/s has to be sustained.

- Algae - Bacteria: Filament Slime - Microbiological activities Iron Manganese Sulphate

Table 2 Additional flow rate required during flushing of drip laterals at 0.5 m/s

Typical nominal pipe diameters

Internal diameter

Additional flow during flushing































Within the lateral that is being flushed, there will be a great pressure variation over the length of the lateral as the bottom end is open to atmosphere. However, the emitters will continue to discharge water. This great pressure variation will result in a sequentially reducing discharge of each emitter along the lateral’s length, including pressure compensated emitters at the point where the pressure drops below their minimum pressure level. (Austen, 2016). Depending on the length of the laterals, additional pressure may be required to sustain the flushing velocity in the laterals. Care should be taken not to exceed the maximum pressure for all the products (manifold, laterals, start connectors and “grommets”) in the block. Generally, dripperline manufacturers specify a pressure for flushing that is higher than the normal working pressure. The additional flow and pressure demand on the system during flushing will determine how many laterals can be flushed simultaneously. It is recommended to only flush one or two laterals together. Systems with variable speed drives (VSDs) at the pump station will be less sensitive to more laterals being flushed simultaneously.



How to ... Lateral flushing procedure

Table 3

Step 1: Preparation

ff In order to flush laterals effectively and check the proper operation of the micro irrigation system, you will need the following equipment:

Maximum time within which a 1 litre bottle should fill up at 0.5m/s

Typical nominal pipe diameter

Internal diameter

Time required to fill a 1 litre bottle at 0.5 m/s






























An empty 1 litre bottle

A stopwatch

Pliers may be required to open the lateral if it is bound with wire at the end

Step 2: Flushing the laterals

ff Remove any ties at the end of the lateral that is keeping it closed.


ff Open the lateral and allow the water to flow without any restriction, such as where the pipe was folded over. Depending on the condition of the system, dirty water or even mud must be allowed to flow out until the water is clear.

ff Laterals can be opened and closed three times to bring about a pressure fluctuation, by placing a thumb over the end of the pipe, allowing pressure to build up before allowing water to flow out again. Certain drippers will go into a self-cleaning mode because of the repeated pressure fluctuations that will flush dirt out of the drippers themselves (and not only the pipe).

If the measured time is more than the value shown in the table, the flushing velocity in lateral is below the ideal value of 0.5m/s and therefore flushing may not take place effectively. Possible causes include: ff The design and lay-out of the system (laterals too long and/or running uphill) ff Pump capacity (not supplying adequate additional flow and/or pressure) ff Too many laterals being flushed simultaneously. Consult your SABI Approved Irrigation Designer for assistance with system design and management problems. For a list of Approved Designers, please visit Photos taken at Plaisir de Merle estate, Simondium. Assistance from Distell staff is gratefully acknowledged.


Step 3: Checking the velocity

ff In order to check whether the flushing velocity is meeting the requirement of 0.5 m/s, a simple measurement can be done using the 1 litre bottle and the stopwatch. The table below shows the time it should take, in seconds, to fill up a 1 litre bottle if the velocity in the specific pipe size is 0.5 m/s.

Kenyan economist wins prestigious Award

For his work in innovative insurance for cattle and livestock in dry areas


r Andrew Mude, a research scientist at the International Livestock Research Institute in Nairobi was recently named the 5th recipient of the prestigious Norman Borlaug Award, endowed by the Rockefeller Foundation, for Field Research and Application for the under 40s, for his work in providing insurance to livestock herders in East Africa’s drylands through innovative, state-of-the art technologies.

Dr Mude won the Award for his work in developing insurance for never-before-insured communities whose livelihoods depend on herding cattle, goats, sheep and camels in the remote, arid and drought-prone lowlands of the Horn of Africa. Mude has made novel use of satellite data to achieve an innovative and highly effective solution that helps pastoral livestock herders reduce the considerable and costly drought-risk they face in this region. An independent jury of experts chaired by Dr. Ronnie Coffman selected Dr. Mude from an impressive group of candidates who were evaluated based on the attributes and accomplishments that reflect those demonstrated by Dr. Norman Borlaug during his work at the Rockefeller Foundation in developing highyielding, disease-resistant wheat in Mexico and introducing adaptable wheat varieties into India and Pakistan during the 1950’s and 60’s, for which he received the Nobel Peace Prize in 1970.


At an event hosted by Director General Jimmy Smith of the International Livestock Research Institute (ILRI) in Nairobi, Kenya, Mude’s selection as the winner of the 2016 Borlaug Field Award for individuals under the age of 40, was made by Ambassador Kenneth Quinn, president of the World Food Prize Foundation, headquartered in Des Moines, Iowa. “Dr. Mude reflects Borlaug-like persistence in his science-based, community mediated, and innovative approach to providing financial protection, through insurance, to millions of poor herders and their families who care for and depend upon their livestock as they move across the vast rangelands of East Africa,” Quinn said, adding that “It should be a matter of great pride for Kenya that two of the first five Borlaug Field Award recipients are Kenyans.” Dr. Charity Mutegi, also of Kenya received the award in 2013.


Reducing vulnerability to droughts Mude will be formally presented with US$10,000 and the “Norman Borlaug Award for Field Research and Application, Endowed by the Rockefeller Foundation”, on October 12, 2016, in a ceremony, in which Rockefeller Foundation President Judith Rodin will participate, in Des Moines, Iowa, USA, as part of the 2016 World Food Prize international symposium. A Kenya native who received his Ph.D. from Cornell University, 39-year-old Mude is a principal economist at ILRI. He spearheads a program called “Index-Based Livestock Insurance” (IBLI), which is greatly reducing the vulnerability of East Africa’s livestock herding families to recurring droughts, which kill great numbers of livestock, sending many hungry households in remote regions into deep and lasting poverty. Since launching IBLI in 2008, Mude and his team have engaged local herders and leaders in building and delivering extension education programs— employing videos, cartoons, and radio broadcasts—to increase understanding of the principles and coverage of the insurance plans. Before Mude’s innovative approach was implemented, African herders had no access

to livestock insurance. It was highly impractical and costly for insurance claim adjusters to travel through East Africa to confirm dead animals and pay claims. IBLI eliminates the need for such visual confirmation of stock losses by using satellite data to monitor grazing conditions – when these conditions are seen to fall below a certain threshold, this data serves as a proxy for dead animals, and insurance payouts are made. By early 2016, 11,800 IBLI contracts had been sold (representing an insured livestock value of $5,350,000) and $149,007 indemnity payments made to insured pastoralists. In future, more than 50 million pastoralists across Africa are expected to have an opportunity to benefit from this financial technology.

Model Citizen-Servant “Dr. Mude represents the type of citizen-servant we as a government are proud to partner with; a citizen dedicated to helping grow the productivity and welfare of the Kenyan people,” said the Honourable Willy Bett, Cabinet Secretary in the Kenya Ministry of Agriculture, Livestock and Fisheries. “It’s because of his passion, commitment, and technical competence that we’re now planning to replicate this novel insurance scheme across all of northern Kenya, where some 4 million pastoralists depend primarily on livestock.”




“With today’s changing climate, weather-based insurance has become a critical tool in building the resilience of some of the world’s most vulnerable populations.” Said Mamadou Biteye, Managing Director of The Rockefeller Foundation Africa Regional Office.

government’s KLIP has already provided 5,012 households with IBLI coverage and just last week (August 24, 2016) it made indemnity payments to a few hundred herders in Kenya’s huge and arid northern county of Wajir, which has suffered prolonged drought.

“By utilizing the most current technology, Dr. Mude’s innovation is helping pastoralist livestock herders protect their livelihoods. We can provide farmers with no better form of food security than by empowering them to protect themselves from the impacts of climate change.”

Take it to the farmer”

“We have the satellite technology needed to monitor grazing conditions in the remotest of regions,” Mude said. “We should be using it to ensure that Africa’s remote livestock herders have access to basic insurance farmers around the world take for granted. We draw inspiration from Borlaug’s lifelong commitment to make his research make a difference. Together with many partners and the herders themselves— and only together—we’re determined to find new ways to help millions of people continue to practice the oldest form of sustainable food production the world has ever seen.” As reported this week from Mude’s IBLI team, the

In Ethiopia, Kenya’s neighbour to the north, a government pilot project spearheaded by Mude’s team is working to scale out this insurance program while the World Food Program is making IBLI-type insurance a key pillar of its food security strategy in Ethiopia’s pastoralist lowlands. Other governments and development agencies are seeking help in testing IBLI-type policies across West Africa’s Sahel and the drylands of southern Africa. ILRI Director General Jimmy Smith agrees. “’Take it to the farmer’ are reported to be the last words uttered by Norman Borlaug before he died. Andrew Mude and his team, working with the Kenyan and Ethiopian governments and others, have taken Borlaug’s injunction to heart, and are taking it even further—to thousands of individual pastoralists raising and herding their animal stock across the vast, remote and generally inhospitable drylands of the Horn of Africa.”

The Jury was impressed by the winners, in particular their exceptional creativity, unrelenting diligence, enthusiasm and true passion for water.

By examining the efficacy of natural water collection by plants – especially in terms of the shape of plants that collect and capture water – Sureeporn Triphetprapa, Thidarat Phianchat and Kanjana Komkla built a device that mimics the water retention of the Bromeliad plant. The device has also been installed on rubber trees on rubber plantations.

Their accessible, practical solution is simple. The selection of local plants, previously undervalued, has made this innovation costeffective to implement, and at the same time scientifically sophisticated,” the Jury said.

SB Pumps and Valves South Africa has won a sizeable contract to supply advanced magnetic drive pumps to a large refinery in Russia where they will be used to pump potentially hazardous gas oil, Goudron and Mazout products.

company has also sold hundreds of standard-type RPH pumps to the petrochemical industry and these have proven to be well supported throughout their lifespan by the company.

The locally developed RPHmdp pumps were selected for their ability to completely separate the drive-ends from the wet-ends of the pumps which are in contact with the dangerous materials being circulated. Instead, KSB’s RPHmdp pumps use separate magnetic drives to power the impellors and so negate the need for the traditionally used Plan 53 pumps.

pumps, quality construction and the long-term ability of our global group to support and maintain the pumps within a mission critical environment. The pumps also needed to be specially manufactured to withstand extreme operating temperatures of between -70˚C and 380˚C, as well as withstand pressures of up to 40 Bar as per API requirements.

The popularity of magnetic drive pumps has also been spurred by stricter requirements of TÜV and other verification agencies for seal-less pumps to be used in chemical and petrochemical plants where potentially hazardous materials are being handled. In addition, the pumps are easily serviced, do not need constant supervision

The magnetic drive pumps require significantly less maintenance and are a safer option than the older Plan 53 pumps, which are complicated and require pressure regulated seals on either end of the pump to prevent hazardous liquids from leaking with potentially disastrous consequences. The older pumps also require constant management and maintenance to ensure that they are 100% sealed and operational at all times.

“This was vetted by our Russian counterparts who conducted an in-depth inspection of our manufacturing facility to ensure production of the highest quality would be met and that API standards were in place. In addition, KSB Russia representative, Vladimir Dragonman, also needed to be satisfied that the South African operation would be able to provide full back-up and support of the pumps whenever required. Needless to say, we far surpassed his expectations and he went back to Russia more eager than ever to continue with the deal,” says Jan.

Strict requirements By contrast, KSB Pumps and Valves product manager, Jan van Vuuren, says the 18 locally developed RPHmdp pumps supplied for the project do not require seals and therefore do not need nearly as much maintenance nor supervision as the old type. “In the case of the Russian Samara Transneft Refinery project, the deal was awarded to KSB Russia on merit of the advanced nature of the

Good track record He continues that another key reason why the refinery, one of the largest of its type in the world, chose RPHmdp pumps is due to the pumps’ good track record at a number of petrochemical companies throughout the world (including Sasol) where they are successfully using these pumps in place of the old Plan 53 pumps. In Russia, and globally, the



and have wet-ends that are fully interchangeable with the company’s standard RPH pumps making for commonality of spares and maintenance. “With European standards calling for seal-less pumps and the movement towards simplicity, reliability and durability in the petrochemical and other industries, we are confident that the KSB RPHmdp will become the defacto pump wherever potentially hazardous materials are required to be pumped under difficult conditions,” concludes Jan.


A tale of clean cities, water and sanitation – new research … Strong local leadership is key Urbanisation pressure can be positive


ith over half (54%) of the global population now living in urban areas, city infrastructure is struggling to keep up in many countries, leaving millions without access to clean water and toilets, increasing the risk of disease. However, progress is being made.

New research from WaterAid has identified the ingredients of success for tackling the ever-growing sanitation challenge caused by uncontrolled urbanisation across the developing world, with strong leadership being key to effecting change. A tale of clean cities: insights for planning urban sanitation

from Ghana, India and the Philippines explores ‘what works’ by examining how three cities have made significant strides in ensuring access to sanitation services for all urban dwellers. Strong local leadership proved vital to success in all three cases, be it from the mayor or the head of the waste management department.

While rapid urbanisation poses huge challenges, the pressure it causes can actually be positive, driving demand for services to be provided. Efforts were also driven by financing opportunities, commercial competitiveness or tourism, and even by crises, such as outbreaks of disease.

Municipal departments Findings also showed uneven progress along different parts of the sanitation chain, such as access to toilets, emptying septic tanks, and treating the faecal waste. Meanwhile, inadequate financing and a lack of coordination between municipal departments are frequent obstacles. Furthermore, the urban poor and those who live in challenging areas are being left behind, the research found.

Water fishing village into the financial capital of the state of Andhra Pradesh inspired political buy-in, which drove initial investments in sewers and the treatment and reuse of wastewater but failed to reach poor neighbourhoods. Sanitation efforts have recently received a significant boost from the launch of Prime Minister Modi’s Swachh Bharat (Clean India) Mission.

Innovative solutions that have been shown to work range from public toilets managed through public-private partnerships, to public campaigns on cleanliness to create tourist-friendly spaces, and from decentralised sanitation wastewater treatment to centralised pit emptying services. WaterAid’s report, released at Stockholm World Water Week this year, provides guidance for municipal authorities, national governments, donors and development agencies to support the UN Global Goal to ensure improved sanitation for everyone.

Three cities All three cities are success stories in their own way and provide useful insights to learn from: • Rapid urbanisation in Visakhapatnam, India, led to almost half the population living in slums. The strain on resources resulted in water scarcity and problems with sewage and open defecation. The desire to transform the once small

Although Ghana is making significant strides in development, the lack of progress in water and sanitation is holding it back. However, the country’s second-largest and fastestgrowing city, Kumasi, has bucked this trend, almost eradicating open defecation and so helping prevent outbreaks of disease, such as cholera. Demand from an influx of traders, transient workers, and migrants for proper toilets, drove the city to invest in pay-per-use public toilets.

these are managed through public-private partnerships, ensuring sustainability, but can present issues as quality of service is very low in many poor neighbourhoods.

Fifty-four per cent of the world’s population now live in cities putting major strains on city planners to extend drinking water and sanitation services to all.

San Fernando, La Union, in the Philippines is lined with beautiful beaches, making it popular with tourists, fuelling demand to keep the water clean and ensure good sanitation provision. Through strong leadership from the Mayor, the city has rolled out environmentally-friendly strategies where sanitation was a key component, even introducing a sanitation tax. They have used various approaches to address the needs of the different areas of the city, resulting in an improvement in city-wide sanitation. Legislation and public awareness campaigns have been key ingredients of success.

“Our research shows there is no one size fits all when it comes to ensuring sustainable sanitation services in urban areas. However, the ingredients for success include strong leadership, with key drivers being national political influence, economic motives, and pressure posed by rapid urbanisation. City sanitation planning is important, but is not a silver bullet. Planning must be adapted to the specific context and phase of sanitation development, and be linked to financing opportunities to avoid it being treated as a tick box exercise.

Andrés Hueso, Senior Policy Analyst for sanitation at WaterAid, said:

“One worrying shortfall identified is that the needs of the urban poor are rarely a top priority. WaterAid believes we must always aim to reach the poor and most excluded people, ensuring sanitation services reach everyone everywhere by 2030.”
