Editor’s message Lessons learnt from the drought

About SABI

Cape Town-headquartered SABI (South African Irrigation Institute) aims to boost optimal irrigation methodologies, water conservation and sustainability.

Carol Posthumus

ne thing is for sure, Cape Town has learnt a lot from the drought. When O we were in the middle of the dry months – queues at taps, the unforgettable two-minute showers, the persistent sound of boreholes being drilled – most of us said “let’s not forget what this is like so we don’t waste one drop of water again”. For us working for SABI, all about optimum irrigation and water conservation, it was fun and gratifying to hear people talking about subjects such as water meters, JoJo tanks and groundwater everywhere you went – every day conversation started to sound like the passionate water savers at SABI get togethers.

Unpacking

People started to “talk water” like they were in the water business – and they have never stopped, which is just so great. Water has been placed high on the agenda in popular culture in Cape Town, and the city, you got to admit, has done it so elegantly!

In this edition of SABI magazine we have an-depth article from a renowned group of researchers in water and irrigation about the impact of the Western Cape drought 2017-2018 (pg 18). The three dry winters of the past years caused dams to drop to record levels – it was so bad that storms of dust clouds could be seen over the desiccated dry dams.

Many new business ventures, responding to need, have been born from the drought. Reportedly, manufacturers of shampoo were even inspired by the drought to introduce a new range of dry shampoos.

It is super to see that the lessons learnt from the drought are being disseminated via studies and media. UCT recently announced that its African Centre for Cities has released a paper, ‘Unpacking the Cape Town Drought: Lessons Learnt’.

“As a result, firm measures were implemented to avoid potential disaster by a combination of establishing new

SABI promotes the sharing of water sources, decreasing unproductive water losses (leakages) and firm water restrictions. The impact of the drought on irrigated agriculture during the 2017-18 season has been high. The total economic loss is estimated at ZAR6 billion with 30 000 jobs lost in the agricultural sector,” say the writers – do read on by turning to page 18, this is a must-read. Vergelegen We have a fantastic report too on Vergelegen wine estate’s eradication of alien vegetation – it took the historic estate many years, but it was worth it. No more water-sucking alien plants on the beautiful estate in Somerset West. Well worth a visit if you are ever in the Cape Town area! Here’s hoping the Western Cape enjoys wonderful winter rainfall, while remembering the lessons from the drought. We hope you enjoy this edition

Load shedding solutions & Water saving wineries

I

rrigation is, of course, reliant on energy, and the recent rolling black-outs or load shedding affected irrigation schedules, at cost to the farmers, many of whom are still trying to recover from drought conditions. Agri SA said load shedding had a “devastating impact on farming activities”.

Irrigation-reliant and energyintensive agriculture such as dairy, grains and horticulture were severely affected by loadshedding, there is no doubt of that. Loss of production and damage to irrigation equipment and technologies may also be impacts of load shedding.

have already been built. Alternative forms of energy – while with high capital cost – certainly look to be one form of a solution.

South Africa’s food security is affected by load shedding as over 25% of the country’s food is produced by irrigation-reliant and energy-intensive industries.

Don’t miss our in-depth article on the impact of the 2017-2018 Western Cape drought. Indeed, the team writes that the impact of the drought on irrigated agriculture during the 2017-18 season was high. The total economic loss is estimated at ZAR 6 billion with 30 000 jobs lost in the agricultural sector.

Solar farms have been mooted as a solution – in fact 13 solar farms

Water saving and wine are also aptly examined in this edition.

One of South Africa’s oldest wine estates Vergelegen has achieved fantastic water savings by eradicating alien vegetation at the historical and beautiful estate. It has taken Vergelegen 14 long years to complete the eradication of alien vegetation project. South Africans have been collecting Awards recently – from Paternoster’s Wolfgat which was voted Best Restaurant in the World to Nederburg and KWV being voted amongst the much-anticipated Most 50 Admired Wines in the World by UK-publication Drinks International. Moreover, in great news, Dr Jackie King was, on World Water Day, named the 2019 Stockholm Water Prize Laureate for her contributions to global river management.

Dr King, retired from UCT and now with UWC, has advanced the scientific understanding of water flows, giving decision-makers methods and tools to assess the full range of costs and benefits when managing or developing river systems. We congratulate Dr King, and also the winning wine Estates! We are proud of our South African talent in water and wine. Please turn to page 46 for the latest on SABI National Congress.

Back to nature at Vergelegen Water-guzzling alien vegetation Completely cleared

T

here have been a lot of celebrations at Vergelegen – one of South Africa’s oldest wine farms. The Estate has hosted many greats over the years – from presidents to royalty.

It was, however, a celebration of a different sort when Vergelegen wine estate in Somerset West completed South Africa’s largest private alien vegetation clearing environmental project after 14 long years.

SABI | APRIL/MAY 2019

Two eucalyptus trees were ceremoniously felled at Vergelegen wine estate in Somerset West – and the crash that resounded through the picturesque valley marked the completion of South Africa’s largest private alien vegetation clearing project.

A vast area of 2200 hectares of densely packed pine, acacia and eucalyptus has been cleared in a visionary programme initiated in 2004 and funded by estate owners Anglo American plc. Prior clearing from 1995 was funded by estate profits.

The 3000-hectare estate is now home to burgeoning fynbos. Rare and endangered plants and grasslands have regrown, and numerous birds and mammals have returned to the 318-year-old estate, attracting local and international researchers.


Wine estates

Vergelegen Support “Today we can finally celebrate the conclusion of a project that has been daunting at times,” said Vergelegen CEO Don Tooth. “It’s involved blood, sweat and tears and everyone involved can be proud of contributing to a South African success story.

ff Size of the estate – 3000 hectares; ff Size of the environmental project – 2200 hectares; ff Size of the area to be declared a private nature reserve – 1900 hectares; ff Clearing was initiated in 1995, at the time funded through estate trading profits. ff Anglo American plc recognized the magnitude and importance of the project and funded it from 2004; ff Jobs created – an average of 137 jobs per annum over the full duration of the project; ff Maximum alien plant density – 80 000 to 100 000 stems per hectare; ff Three fires – 1997, 2009 and 2017 – devastated the estate and necessitated reclearing most of the areas that had already been rehabilitated.

“I would like to congratulate every member of the team, and to thank Anglo American plc for their commitment. We’ve faced setbacks such as fires burning rehabilitated land, yet their unwavering support has made the project possible.” Honorary guests at the celebration included Minister Anton Bredell, Western Cape MEC Environmental

Affairs, and Norman Mbazima, Deputy Chairman of Anglo American South Africa. Vergelegen was acquired by Anglo American plc in 1987. The environmental investment forms part of an extensive programme to restore the historic estate and establish it as a showcase of South African heritage, culture, wine and biodiversity. The estate is open to the public and is viewed by 100 000 visitors a year, half of whom are international visitors.

Private nature reserve Tooth confirmed that the restored land will be preserved for future generations, as 1900 hectares of the estate will be promulgated as a private nature reserve with

the same protection status as the Kruger National Park. The programme has created many work opportunities in the local Helderberg community. Previously unemployed residents have acquired skills such as brush cutting, hand-picking alien seedlings, chainsaw operation and herbicide application, and first aid training. Now that the clearing and felling of alien vegetation is complete, a smaller work force will continue to be employed for annual follow-up work in the cleared areas. Ongoing maintenance ensures that re-emerging invasive aliens will be removed before producing seeds.

Scientists and students The natural diversity has also attracted scientists and students and Vergelegen has shared its knowledge and facilities through the establishment of an informal “Centre of Learning Excellence”. To date 22 formal qualifications have been obtained from work done during this project, 17 from local institutions and five from international universities. Ecological treasures on the estate include the re-emergence of 15 hectares of critically endangered Lourensford Alluvium Fynbos and 105 hectares of critically endangered Swartland Shale Renosterveld.

The project has unlocked water resources and restored 80 hectares of wetlands, fed by the Hottentots Holland mountain range catchment area. These form an ideal habitat for birds, amphibians, invertebrates and mammals such as otters, mongoose and small buck. Vergelegen also conducts monthly bird counts, identifies wild flowers and uses infra-red camera systems to monitor wildlife movement. Species such as Cape leopard, caracal, honey badger, grey rhebok and spotted genet are regularly spotted. The number of bird species has soared from 80 to at least 152. Some 279 plant species have been recorded, including 22 on the Red Data List.

Wildlife at Vergelegen • One of the most satisfying factors • has been the return and recording of an increase in the number of bird and animal species. Vergelegen is cooperating with the Cape Leopard Trust and to date five different • leopards have been photographed and identified.

In cooperation with CapeNature, a herd of endangered bontebok, 11 in total, were transferred to the estate for observation and rehabilitation. They now roam freely and total 47. Bird species counts are conducted monthly; from an initial count of 80 in 1995, this number has increased to 152.

Insect life has also increased exponentially with the growth in natural predators, allowing Vergelegen to reduce its insecticide sprays by 75%.

Energy

South Africa must end its coal habit. But it’s at odds about when and how by Jacklyn Cock

S

outh Africa’s power utility Eskom is in crises. In recent weeks, this has been brought home to South Africa’s 58 million citizens as major power cuts hit the country. The blackouts have renewed focus on the power utility’s economic and technical problems. But Eskom’s problems point to the much bigger issue of a country struggling to map out a new energy regime – one that reduces its very high levels of dependency on coal in a way that doesn’t devastate people’s lives.

POWERING AGRICULTURE PRICES START FROM R36.00 FOR ER14505 AND R110.00 FOR ER34615H

South Africa is highly dependent on coal – almost 90% of its energy comes from coal-fired power stations. The urgency of change is clear on both global and local levels. Mining and burning coal is one of the most destructive activities on the planet. It represents an immediate threat to all forms of life and to scarce supplies of water, the degradation of arable land and toxic pollution of the air and water with extremely negative health impacts. South Africa isn’t the only country in the world attempting to adjust its energy mix by moving away from fossil fuels to cleaner power sources. Dozens of countries such as Germany, Austria, Canada, Ghana and the Philippines are attempting to make the change.

But, despite policy commitments, South Africa isn’t doing enough to make these changes through what’s become known as a “just transition”. This is a contested notion with different understandings of the depth and direction of the change involved. At the very minimum it means making provision for vulnerable workers in the energy

10

SABI |APRIL/MAY 2019

sector, to make sure that the move towards a low-carbon economy is done in a way that protects jobs as well as the environment.

Contradictions in policy Contradictions in the country’s approach to the transition away from coal are evident in the Draft Integrated Resource Plan announced by the Minister of Energy in 2018. But it only mentions the partial decommissioning of Eskom’s 16 coal-fired power plants and of reducing South Africa’s reliance on coal for energy to less than 20% by 2050. The document appears oblivious to the immediate urgency of responding to climate change. Rather than being “too ambitious”, the plan is not ambitious enough. The country is also contradictory when it comes to the “just” elements of the transition. Mineral Resources Minister Gwede Mantashe has referred to “the government’s commitments to a just transition” but in the same speech he urges the mining industry to “take pride in itself and articulate a more positive image.” Specifically, he said coal producers must “wake up. You are under siege”.


Energy In reality the people who are under siege are poor people who are the least responsible for climate change but who are carrying the heaviest costs.

Commitment to action Examples include the many communities living close to coal-fired power stations as well as people working in open-pit or abandoned mines. Others affected badly by mining include people dealing with dispossession, loss of land and livelihoods, threats to food security, limitations on access to water resources, health problems associated with air pollution and the desecration of ancestral graves. There’s a desperate urgency for South Africa to take seriously its commitment to a just transition. The South African Federation of Trade Unions supports the move to renewable energy but has estimated that without a just transition that “protects the livelihoods of mining and energy workers, some 40,000 jobs will be lost.”

Powerful social forces such as the Congress of South African Trade Unions, the South African Federation of Trade Unions and the National Union of Metalworkers of South Africa support a transition to renewable energy. But they insist that is shouldn’t be done at the expense of ordinary South Africans. That means that it there can’t be privatisation of state assets at the expense of jobs and higher electricity prices. This is understandable given the country’s high unemployment rate.

Eskom The restructuring of Eskom is obviously necessary. And there are strong economic and ecological arguments for shutting down inefficient coal-fired power stations and savings to the country would also be significant. One study on Eskom’s financial crisis claimed that to decommission the Eskom power stations at Grootvlei, Hendrina and Komati

power stations and avoid the completion of Kusile units 5 and 6 would give rise to savings of around R15 billion – R17 billon. But none of this should happen at the expense of workers. Yet there are signs that it already is. Decommissioning is already underway. For example, two units at Hendrina – one of Eskom’s five coal-fired power stations to be closed by 2020 – have already been closed. The remaining eight will be closed by April this year. Yet there’s no protection for the bulk of the workforce, 2,300 of whom are contract workers hired by labour brokers. The power utility is taking no responsibility for what happens to them. There have been calls by activist groups for a committee driven by the presidency to coordinate a just transition. But nothing has materialised. The current “solutions” to the Eskom crisis – a reliance on overseas experts, union bashing and backdoor privatisation – don’t bode well. All suggest a familiar panic on the part of the powerful.

What’s needed There is no blueprint for a just transition; it has to be built in an inclusive process of democratic debate and participation including coal mining affected communities and workers. This needs to be grounded in the recognition that coal mining and burning is a driver of environmental inequality and injustice in South Africa. What is required is militant, class–based activism to challenge existing power relations and to mobilise for a radical just transition. This involves changing – not just Eskom – but ways of producing, consuming and relating to nature to create a more just and sustainable world.

Pumps Valves and Pipes

Conference to address Industrial Internet of Things (IIoT) At Pump Valves and Pipes expo

A

delegation of local and international engineering professionals together with an unbeatable line-up of thought-leaders in Africa’s extractive, construction, energy, food processing, agriculture, water & waste water and power generation industries will be at the Pumps, Valves & Pipes Africa 2019 expo and conference in Johannesburg at Gallagher Convention Centre (Midrand) from 11-13 June to address latest technologies and proactive approaches to challenges in the operation and maintenance of pumps, valves and pipes.

The growing demand by processing and manufacturing plants for Industrial Internet of Things (IIoT) solutions is testament to how important it is not to stay behind in this day and age. Connecting industrial assets like pumps, valves and pipes to the Internet and wireless technologies is a strategic enabler for improved manufacturing performance. When properly implemented, it can provide appropriate security

and availability of services across multiple plants and facilities. Says programme manager, Nico Loretz: “It is against this background that INDUTEC will be hosting the 11th edition of Pumps, Valves & Pipes Africa. For the first time ever, the event is set to be boosted by sharing the stage with two chief construction events: African Construction Expo and Totally Concrete Expo, ensuring a

broader audience mix and larger platform for the involved industries to network and do business.”

Energy and cost saving solutions The free-to-attend workshops and conference sessions will look at standards and compliance; selection criteria; energy- and cost saving solutions; reconditioning; as well as the efficient operation and maintenance of pumps, valves, pipes, tanks, vessels and drums. The high-level joint keynote plenary session will look at how the PVP industry could leverage off fast growing economies and be best positioned to meet Africa’s construction boom needs. Localisation and skills for indus-

trial development and engineering as well as strategic sourcing and supply of industrial assets for the conveyance of liquids, gases & slurries will also be addressed. “The Advisory Board for the programme includes representatives from PetroSA, SAPREF, Eskom, AngloGold Ashanti, Rand Water and Astral Foods and the South African Irrigation Institute (SABI) – ensuring a most relevant and current programme designed by the industry for the industry”, concludes Loretz.

teacher, Tim Baker, became Principal. It was also around that time that celebrity chef, Jamie Oliver, had begun campaigning for healthy school meals. Tim felt strongly that healthy living could be integrated into school life by using food to deliver almost all of the school syllabus’ learning objectives. Here pupils learn how to grow plants, where food comes from, what seasonal produce tastes like, how important fresh, nutritious food is for healthy growth, the importance of recycling (it has its own Eco Team) and much more… Chicken run and beehive

River flow champion, South African scientist Dr Jackie King, wins 2019 Stockholm Water Prize

D

r Jackie King was, on World Water Day, named the 2019 Stockholm Water Prize Laureate for her gamechanging contributions to global river management.

She has advanced the scientific understanding of water flows, giving decision-makers methods and tools to assess the full range of costs and benefits when managing or developing river systems. Dr King led the early development of the methods as a researcher at the University of Cape Town, funded by South Africa’s Water Research Commission. Later, she and colleagues Dr Cate Brown and Dr Alison Joubert created ecosystem models to demonstrate the ecological and social implications of damming and de-watering rivers. This has enabled objective assessment of the costs of waterresource developments that could emerge linked to benefits such as hydropower and irrigated crops.

Raising awareness Her commitment to raising awareness of the value of rivers and their importance for millions of people has made Dr King highly regarded by academics and water managers globally. In its citation, the Stockholm Water Prize Nominating Committee notes that “Dr Jacqueline King has,

through scientific rigour, selfless dedication and effective advocacy, transformed the way we think, talk and work with water as a flow of and for life.” Dr King’s early work influenced South Africa’s 1998 National Water Act and is increasingly

water resources understand the potential benefits but not necessarily the costs in terms of degrading rivers. We can now show these ecological and social costs at a similar level of detail to the benefits shown by planners. This is a new kind of information, not available until the last few years, that helps governments better understand the trade-offs involved in development as they decide on their preferred future.

“I find it humbling, energizing and very rewarding. I have never sought high-profile jobs but was happy to be a working scientist, free to say what I felt needed to be said. I am delighted that the silent voices of river systems and their dependent people are increasingly being acknowledged. We all lose if rivers become severely degraded due to poorly-informed development and management. It does not have to be like that.” Dr Jackie King

and an independent consultant. As an aquatic ecologist she became influential in the recentlyestablished field of Environmental Flows. Her early research focused on South African rivers but since the 1990s she has moved into advisory work on river systems across Africa and Asia. Dr King’s work has been recognized with both the Gold and Silver Medals from the Southern African Society of Aquatic Scientists and with South Africa’s “Women in Water” Award in the research category. She was also the 2016 recipient of WWF-South Africa’s “Living Planet Award”. Her academic work includes over 100 refereed items in books, international journals and conference proceedings.

Healthy rivers Dr King is clear that governments have the right to decide their own path to development. She strives to support them by providing transparent and accessible information so they can effectively assess their different options. Dr King has helped decisionmakers understand that healthy river ecosystems are not a luxury, but the basis for sustainable development.

The prize will be presented to Dr King by H.M. King Carl XVI Gustaf of Sweden, Patron of Stockholm Water Prize, at a Royal Award Ceremony on 28 August, during World Water Week in Stockholm.

Drought impact

What was the impact of the Western Cape’s 2017-18 drought? by Ruben Goudriaan, Caren Jarmain, Mechteld Andriessen, Kristin Abraham, Roan Naudé, Peter Keuck

I

n the Western Cape of South Africa all eyes were focused on the taps during the 2017-18 summer. Dust storms could be seen clouding the sky above bare dams as shown in Figure 1. Three dry winters in a row caused dam levels to drop to record low levels. At the end of October 2017 the average dam storage level in the Western Cape was approximately 39% ; by far not enough to fulfil all domestic, industrial and agricultural water demands during the South African summer. As a result, firm measures were implemented to avoid potential disaster by a combination of establishing new water sources, decreasing unproductive water losses (leakages) and firm water restrictions. The impact of the drought on irrigated agriculture during the 2017-18 season has been high. The total economic loss is estimated at ZAR 6 billion with 30 000 jobs lost in the agricultural sector 1,2 .

Figure 1 Dust-storm in Theewaterskloof Dam. Theewaterskloof Dam is the biggest dam in the Western Cape and responsible for feeding water to Cape Town as well as the local agricultural community.

During the 2017-18 summer production season water restrictions of 50% were implemented in the Breede Valley, 60% in the Berg River and Riviersonderend region and various other regions and 85% or more in the Lower Olifants River Valley . In response to the water limitations, in many areas crops were

removed and shredded to produce mulch for fields which were kept in production. For orchards and vineyards, this approach will have a long-term impact on productivity as it will take substantial time to replace the trees and vines that were removed. Where such extreme actions were not followed, an insufficient amount of water resulted in a reduction

in yield quantity and quality. It is further expected that the absence of post-harvest irrigations will negatively impact production in the 2018-19 season.

The results from this analysis display the disastrous impact of a drought, but equally show how varied this impact can be in one single province.

Satellite-based data

The FruitLook Project

For this article the impact of the 2017-18 drought on the Western Cape agricultural sector is assessed using satellite-based data products available via FruitLook (www.fruitlook.co.za). The spatial FruitLook data is used to identify the impact of the drought in two distinct regions: the Groenland Water Management area and the Lower Olifants Water Management Area. The Groenland area is relatively wet and indications are the impact of the drought on production levels was minimal during the 2017-18 season. The Lower Olifants area faced a water deficit of approximately 85% at the start of the season .

Since 2011 farmers in the Western Cape have had access to satellitebased crop monitoring information via FruitLook (www.fruitlook. co.za). Complete funding by the Western Cape Department of Agriculture makes the use of FruitLook free of charge for the end user. Via the provision of smart satellite-based data products FruitLook assists in the efficient use of water resources by farmers. Between August 2017 and April 2018 via FruitLook over 750 users monitored more than 50,000 ha of agricultural land. Satellites can see more than the human eye: for example, nearinfrared light, visible to insects but not humans can be captured

Drought impact via modern sensors mounted on satellites. Via an ingenious combination of satellite data sources, weather information and smart models, data is created each week, describing crop growth, water consumption (= actual evapotranspiration) and plant nitrogen content. Through the FruitLook portal this data has been helping farmers to assess crop development, and to take efficient and timely

mitigation measures where needed, leading to an improved crop production process. In the context of water management, farmers can use FruitLook for assessing and comparing field water consumption, assessment of water shortages and crop stress, getting an indication of efficiency of water use, probe placement and interpretation and detection of leakages.

Biomass of table grape field Figure 2 shows biomass production for a table grape field as visible on the FruitLook webportal. The image clearly displays in-field variation in growth. Variation in biomass production can be due to a myriad of reasons, including differences in soil or disease, fungi or other

problems within the crop production process. Figure 2 shows information for only one field; each pixel represents an area of 20mx20m. Analyses exceeding field scale can be done using the dataset as well. The information behind the FruitLook portal is available for all major agricultural areas in the Western Cape as can be seen in Figure 3.

Figure 3 The data behind FruitLook consists of raster maps describing production in the entire Western Cape on a weekly basis. In this case, a biomass production map shows the vegetation growth during from 25 to 31 October 2017.

Drought impact irrigated crop types in this region are pears and apples, with some wine grapes and stone fruit also present in the area. When comparing the 2016-17 production season with the 2017-18 production season,

accumulated biomass production figures are relatively similar. A comparison is made on a field-byfield basis for 4 302 fields covering close to 9 000 hectares. This comparison is visualized within the histogram for the Groenland area displayed in Figure 4.

Figure 5 Map showing impact on actual biomass production due to the effect of the 2017-18 drought in the Groenland water management area. No particular impact of drought is visible on the biomass production figures. The dark red fields were likely removed over the past season. Simultaneously, the dark green fields are likely new in production.

Figure 4 Histogram showing impact on actual biomass production due to the effect of the 2017-18 drought in the Groenland water management area. No particular impact of drought is visible.

Groenland The histogram shows a normal distribution and the average difference between 2016-17 and 2017-18 is almost 0%. This means, for the two years considered in the Groenland area, the amount of fields which showed an increase in growth (biomass production) is similar to the amount of fields showing a decrease in growth. For more than 2/3 of all fields in the region, the difference in accumulated biomass production between the 2017-18 and the 2016-17 production season was less than 10%. It also indicates the amount of fields in production is relatively stable: almost as many fields show a sharp decrease in production as there are fields showing a sharp increase. According to the histogram this water management area displays little to no detrimental

effects of drought. This suggest that this area had adequate water for plant growth and the data reflects the fact that little water conservations measures were needed in this area. This is confirmed in Figure 5, showing the drought impact in a map, where vegetation growth in 2017-18 is expressed in relationship to 2016-17. Most fields show little drought impact (yellow) meaning production during 2017-18 is similar to 2016-17. The data suggests that some orchards were taken out (in red), but also that new fields were planted or came into production (dark green). Although the data considered in this assessment shows vegetation growth (total biomass production) and not crop yield, it would indicate a close to average production season compared to the year before.

A similar assessment for the Lower Olifants water management area (LORWUA) tells a completely different story. The LORWUA region is highly dependent on the Clanwilliam dam, which feeds water through a system of canals to the water users downstream. In this area 90% of all irrigated fields are under wine and table grape cultivation. Especially table grapes are vulnerable for

drought conditions. At the start of the 2017-18 season, the Clanwilliam Dam was filled to 40% of its capacity causing the introduction of major water restrictions for irrigated crop production. Under 20% of the normal water quota was made available to producers.

Drought impact Consequences seen The data clearly shows the dramatic consequences of a season experiencing a severe drought. The histogram (Figure 6) displays the effect of the 2017-18 drought by comparing the biomass production figures to that from 2016-17. Close to 15 000ha was analyzed covering 5 027 fields. On average, nearly 25% less biomass was produced over

the entire Lower Olifants water management area. This perceived drop in production is confirmed by the South African Wine Harvest Report 2018 from Vinpro: low water availability from the Clanwilliam dam let to reduced crop vigor, smaller canopies and increased water stress . Worrying is the number of fields which show a (close to) 100% reduction in growth, indicating the removal of vineyards or their complete die-off.

normal season. In stark contrast, farmers in the Lower Olifants region were watching the sky for rainfall which never came. As the FruitLook data analysis shows the farms in the Lower Olifants region were severely impacted during the 2017-18 production season.

Central Karoo continue to face drought challenges.

It underlines the vital importance of available water as the number one resource most essential to agricultural production. Climate models predict a gradual to rapid change in climatic conditions and an increased likelihood of extreme weather conditions like hail, flooding and prolonged droughts in the Western Cape.

Changing of climate

Agriculture, and wine and fruit production in particular, is vulnerable to this changing of the climate and additional stress from droughts on the already limited water supplies. In combination with significant non-climatic pressures, like increasing competition for water from the urban and industrial sector, climate change forms a potent threat to agricultural sustainability. Figure 7 Map showing impact on actual biomass production due to the effect of the 2017-18 drought in the Lower Olifants water management area. A strong reduction in biomass production is visible for almost all production fields. Additionally, many fields show a (close to) 100% decline in growth which means these fields are likely cleared.

Figure 7 maps this significant decrease in crop growth (biomass production) resulting from decreased water availability. It shows a section of the canal between Klawer and Vredendal. Almost all fields visible on the map show a drop in production figures. The fields colored in deep-red are likely cleared. Assuming a drop larger than 90% indicates permanent removal of the crop, based on the FruitLook data it is estimated close to 200 fields were cleared over the course of the 2017-18 season. This accounts for close to 5% of all vineyards and orchards in the region. At the same time almost no darker green fields are visible, meaning there were nearly no new plantings during the 2017-18 season. The histogram displayed in Figure 6 highlights this too; a significant part of the fields show a -90% drop (or more) in biomass production, while almost no fields show a sharp growth-increase between the two years.

Adding to the difficulties stated above, there was no water available to producers for post-harvest irrigation. The impact of this still remains to be seen during the 2018-19 season. The combined effect of decrease in productive area and the absence of postharvest irrigation means the 2017-18 drought will be felt for years to come in this region.

Conclusion Satellite based data is extremely useful to assess the impact of droughts. The effectiveness of doing so is shown within this article: although the causes, effects and predictions on the 2017-18 drought made headlines throughout the Western Cape, satellite imagery shows the agricultural impact of the drought varied strongly between regions. In Groenland, sufficient water was available enabling the farming community to run a relatively

As such the lessons learned from last year(s) remain vital: water is life, use it wisely and responsibly! References

To live-up to the challenges of the future, the agricultural sector needs to find ways to access more water, and at the same time irrigate more efficiently and with a higher precision. More water might be accessed via expensive measures like the introduction of new dams, increasing the storage of existing ones and increasing groundwater abstraction reducing vulnerability to drought. Simultaneously, fresh water is ultimately a limited resource and the efficient use of water in irrigation is essential for a sustainable (agricultural) future. This is where tools like FruitLook can help. Now and in the future.

Fortunately, the Clanwilliam Dam was completely refilled during the winter of 2018, making the future of agriculture in the Lower Olifants region a lot brighter than it seemed a few months ago. This is also true for most regions in the province where the water situation at the start of the 2018-19 production season was less dire than the previous year. This brings hope and perspective of better times to come. At the same time areas like the Little Karoo and

In the mid-80s RAIN started to produce solenoid valves, and the company has developed a wide range of models over three decades that cover all the needs of the landscape, sports and agricultural markets. Indeed, today RAIN is the largest valves manufacturer in Europe, having sold more than 13 million units of solenoid valves in 76 countries.

RAIN was established in 1968 by engineer Vittorio Stiatti, who invented the well-known irrigation controller ‘PIOGGIATORE’. This innovation has infused within the company, to this day, a passion for innovation and excellence. RAIN holds a number of patents and is a renowned irrigation company and a key irrigation

A lot of precision, care and thought go into RAIN’s solenoid valves and other patented products, making the company’s ranges unique in many ways. Since 2000 more than 10 lines of innovative products have been developed and patented by RAIN, including: ff Open valve boxes, equipped with handle for easy opening ff Manifold System: the complete range of solenoid valves and manifolds for ease of installation and maintenance – quality without any comparison

Model Maker Systems Celebrating our 30th anniversary Serving survey and engineering by Carel Viljoen - CEO and owner, Model Maker Systems

M

odel Maker Systems was registered as a company to develop and sell software in August 1989. This means 2019 is a very special year for us because we are still going strong while many developers in the same field from the 1980’s don’t exist anymore.

Over the years further development and a policy of providing affordable software with outstanding support, helped us become one of the leading suppliers of software. We now have nearly 4000 companies spread over 83 countries using our software. Some of these companies are leaders in their field and of the larger ones around. As far as irrigation designers goes, we have almost 500 companies using more than 1140 IRRI-MAKER packages between them. The disciplines of land survey and civil engineering are the main users of MMS software with its digital terrain modelling and CAD

functionality. During the early 1990’s our software was used by irrigation designers to create contour models and plans to be used as input data for an Israeli irrigation design package. Due to our dedication to development and support these users started asking about us adding hydraulic design functionality to our Model Maker software. With the input and expertise of local irrigation designers we then developed the package that is today called Irri-Maker. At that stage it was the only irrigation design package available complete with terrain modelling, CAD, hydraulic design and infrastructure quantification

in one. Today it is used by the majority, if not all, of the irrigation designers in South-Africa. Most international users are in African and South American countries. The new generation of irrigation designers make use of technologically advanced equipment and methods and we will support them where needed with our software.

Exceptional support We believe our products are affordable and with user friendly and easy presentation provides for a highly productive tool in its field of application. One of the main benefits users have is our commitment to exceptional support and further development to accommodate the latest technologies in hardware and software available. During 2018 we embarked on a new development project that we believe will keep Model Maker

Systems going for the next 30 years or more. We will probably start to test this with users early in 2020. This new product will combine our knowledge and experience of the last 30 years in one single package with functionality from all our existing products. Our main marketing platform these days is the internet, and anyone interested in more information about our software is welcome to visit our website www. modelmakersystems.com . An obligation free quotation can be requested from the site. Our software may be bought outright, or it can be rented on a monthly basis. I am sincerely grateful for all the users of our software who supported us over the years. We made many friends and without these users we would not have been where we are today.

Cannabis grower Switches lights to LEDs Faster growth & increased bud density

H

ighland Grow is a licensed cannabis producer in Nova Scotia, Canada. The company takes pride in being a Nova Scotian founded and operated company that produces top shelf flowers. Highland Grow is a subsidiary of Biome Grow, a startup cannabis conglomerate. Highland Grow is the first of Biome’s four cannabis cultivators to receive its license. The indoor facility’s flowering rooms and mother room are lit exclusively by LumiGrow LEDs. The majority of their vegetative growth room is LumiGrow-lit. “[Here at Biome] we’re cleantech renewable power specialists with a focus on the cannabis industry,” says Khurram Malik, founder of Biome Grow, “We’re always looking to create more efficient facilities from an ecological standpoint, as well as an operational standpoint.”

Started When Highland Grow first started growing, they installed traditional high-pressure sodium (HPS) lights. They quickly ran into challenges in their growing rooms. The HPS

28

SABI | APRIL/MAY 2019

fixtures frequently caused the rooms to overheat and dry out. As a result, the plants were not producing consistently dense buds. Frank MacMaster, president of Highland Grow, began to search for a lighting solution that would allow him to reach his quality goals. Biome, Highland Grow’s parent company, has long been a proponent of LEDs, so it was natural for them to suggest LED horticultural lighting as a solution. Frank was initially sceptical of LEDs. In the past, he’d heard that the technology wasn’t suited for growing cannabis yet. When several growers that Frank trusts recommended LumiGrow, he started to seriously explore switching to LEDs. It soon became

apparent that LEDs emit far less heat than HPS and draw 40% less energy. LumiGrow’s user-friendly smartPAR Wireless Control System and attentive customer service quickly set them apart from the other major LED manufacturers. “We really like LumiGrow’s software interface,” says Khurram, “You can start with a [high-quality LED] chip that comes from the same place, but what it boils down to at the end of the day is how it’s all integrated, and how robust and interactive the control system is. Our HVAC system is quite novel, so it was important to us to find the right LED manufacturer that has the automation, controls, and sensors to go with it.”

Easy trimming and reduced labour costs Highland Grow implemented LumiGrow fixtures with the LumiGrow smartPARTM Wireless Control System in their vegetative growth, flowering, and mother rooms. Frank has carefully performed his due diligence, meticulously testing the LumiGrow

fixtures side by side with HPS before rolling out LEDs across each room. For their first grow, Frank grew half of the flowering room under LumiGrow LEDs, with the other half under the HPS fixtures. He was pleased with how well the plants grew under the LEDs- the buds were substantially denser than the HPS-grown buds. Since strain selection is important, Frank proceeded to test a variety of strains under the LumiGrow lights. Each strain consistently produced dense, high-quality buds. Highland Grow is currently on its fourth grow under LEDs. “[The LED-lit plants] start their pea bud sooner, and are usually ahead of HPS by a few days,” says Frank, “The plants lumber with the weight of the flower when grown under LED… [Once it’s dried] every bud that’s on there is a beautiful form and shape, with good density.” Frank quickly switched the flowering room over to 100% LumiGrow LEDs. He is currently


Greenhouses using three custom spectral programs for flowering. He starts with a lower-intensity program to ease the plants into the flowering stage and make any necessary environmental adjustments. After closely monitoring the plants for around 12 days, Frank applies the high-intensity flowering program that his plants will grow under for another 50 days. In the final few days of flower, Frank applies a finishing program with a high blue-to-red ratio to help the flowers retain more terpenes and THC. “LEDs have come a long way. [In the early days], LED lights weren’t even able to put the bud where it needed to be,” says Frank, “Now we’re taking it a step further and using spectrum to exploit the finish and increase production, taste, and aroma. That’s the difference between HPS and LumiGrow LED lights. Instead of one spectrum of light that’s constant, you can adjust your spectrum to get the most out of your plants.” Frank reports in addition to being attractive and high-quality, the LumiGrow-lit buds are easy to trim and that there is very little waste

left over after trimming. Highland Grow also recently invested in a trimming machine to help them process higher volumes. Since the LumiGrow-lit buds are so dense, they are not damaged by the machine and require less processing time than a fluffier HPS-grown bud.

25% More Branche s Frank has tried growing his mother plants under several other types of light but has continually been dissatisfied with the results. His plants grew slowly under the T5 bulbs, so Frank switched to HPS. However, he found that the HPS fixtures created an uneven spread of heat, which resulted in uneven plant growth. In sharp contrast, Highland Grow’s mother plants are thriving under LumiGrow spectrum. The mother plants produce 20-25% more branches under LumiGrow spectrum than they did under HPS. This ensures that Highland Grow always have enough young clones on hand to cycle through the vegetative growth rooms. “Once we switched to LED light in our mother room, we knew we

wanted to keep it 100% LED,” says Frank, “It is the best change we made [in that room] so far.” Highland Grow is currently finetuning their vegetative growth room’s spectral program, with the goal of shortening crop cycle and improving root growth. Frank has noticed that once the young plants establish themselves, the LED-lit plants tend to grow faster than their HPS-lit counterparts. He currently runs the lights for 20 hours, then lets the plants rest for 4 hours. The vegetative growth phase currently takes 3-4 weeks, depending on the strain. Frank is still learning how each strain responds to LumiGrow spectrum and is experimenting with using new spectral ratios to control plant morphology under LumiGrow’s guidance. Like other flowering plants, cannabis responds to red light by stretching more and responds to blue light by remaining more compact.

Lighting Thanks success

LumiGrow fixtures in Nova Scotia, their facility in Ontario is moving ahead with installing LumiGrow LEDs as their primary source of lighting. Recently, Highland Grow started training employees from their Ontario facility on how to grow with LumiGrow LEDs. The goal is to prepare them for when they receive their cultivation license so that they can come to market with high-quality LED-grown flowers. All future Biome facilities in Canada and International markets will now employ LED lighting following this successful validation at the Highland Grow facility. Frank is proud to be leading the way for LED-adoption in the cannabis industry. “Not many [other licensed producers] coming online are growing under LED lights. They’re too nervous because a lot of LEDs on the market weren’t very effective until this [LumiGrow] light,” says Frank.

How to ...

Build a birdfeeder - by Mike de Villiers The presence of wild birds in one’s garden is always a sight to behold. Putting up a birdfeeder and keeping it stocked with wild birdseed will ensure a constant stream of visitors to your garden. This editorial will describe how to build a simple birdfeeder from materials obtained from your local co-op, nursery or hardware store, as well as some general rules that one needs to observe in order to be a responsible bird feeder.

INTRODUCTION Needless to say, there are countless wild bird species spread around the country, each with their specific habitats and food requirements. This editorial will be concentrating on attracting and feeding the common garden bird species, but for those of you on farms and in the country areas, you will have to cater for the raptors, such as owls and other species not as prevalent in the cities as they were before. However, I am confident that most of our readers are aware of their local species and therefore what their feed requirements are. There are also certain species that move around in such large flocks that they become destructive, especially in the farming regions and one needs to discourage them from settling. The reflectors seen on the roof-tops of public buildings and the automated sound devices used in vineyards are examples of these measures. We are, however, concentrating on the common garden birds that provide much enjoyment to gardeners and homeowners. The main objective of this editorial is to stimulate interest in the feeding of wild birds and to encourage everyone to conduct their own research and use their ingenuity in the set-up and maintenance of a responsible feeding station. BIRD FRIENDLY ENVIRONMENT

REGULAR FEEDING TIME

One can also create a bird-friendly environment that encourages wild birds to visit and even nest in your garden. The most common bird species found in one’s garden are the seed, nectar and insect feeders. There are many indigenous trees and plants that these birds feed on in the wild, which are also both decorative and thrive in domestic gardens. Red, yellow and orange flowers seem to attract the nectar feeders. Examples are aloes, watsonias and red-hot pokers. Seed eating birds like daisies, restios and grass seeds. Plants with berries appeal to other species. Reeds and palm trees also provide nesting material and ideal siting for the weaver birds during the nesting season. Seek Advice from your local nursery and the internet, although one needs to know which species you are trying to attract before you start your search.

Remember that many birds will return at the same time, usually morning and early evening, to feed at your station. These wild birds are more than capable of surviving without assistance from your feeder. Don’t stress when away from home, however given the shrinking nesting environments in our cities and suburbs, birdfeeders do play a role in maintaining healthy wild bird populations.

30

SABI | APRIL/MAY 2019

Some of the most common seed eating birds are: weavers, widowbirds, finches, waxbills, canaries, buntings, doves, bishops, whydahs, quelas, sparrows manakins and pigeons. Other species such as the thrushes, shrikes, white-eyes and robins enjoy meat, suet and grated cheese as well as meal worms whereas starlings will enjoy most of the above.


How to ... PROVIDE CLEAN WATER Providing access to clean water is also a very important aspect to attracting wild birds to your garden, as they need to bathe and drink water regularly. This is especially important in those areas, such as the Western Cape, which are experiencing drought conditions at present. Place a shallow birdbath under the cover of foliage which provides shade and protection from above as well as convenient perches. Do not place a birdbath under a feeding station as the empty seed husks and droppings will contaminate the water leading to the rapid growth of green algae. Sugar water feeders are also popular features in many gardens. Some people believe that too much sugar will damage the beaks of birds and too much red colouring may also be harmful, therefore use some white sugar thoroughly dissolved in warm water with a small amount of red colouring. Input from the Garden Route Birds (GRB) website as well as the Bird Watchers Digest has been used in this editorial and is gratefully acknowledged. Refer to these websites for additional information.

sugars that cannot be digested by birds and has little nutritional value for them. Also avoid avocado pear as it is toxic to parrots and is therefore safer to not give it to any birds. This may seem controversial, but bread is filling and has no nutritional value for birds and also contains preservatives and chemicals. Whole wheat brown bread is a step in the right direction. Rolls, crackers, chips, biscuits and doughnuts should be avoided for the same reasons.

HOW TO BUILD A BIRDFEEDER The following is a step by step procedure to build a “hanging platform� type of birdfeeder from readily available materials. There are any number of variations that can be applied to this type of feeder, however the simplicity of construction is the main advantage of the chosen design. Step 1: Gather all the materials `` `` `` `` `` `` `` `` `` `` ``

1 x 350mm plastic Circular tray 1 x 250mm plastic flower pot 150 x 330 mm plastic rectangular tray 1 x length of 8.0mm galvanized Threaded rod 5 x No.8mm galv. Hexagonal nuts 3 x 8mm galv. Penny washers 2 x 8mm galv. Threaded eye’s 20mm rigid green plastic riser pipe: 600mm long 1 x 100 x 100 x 6mm plastic or wooden support 1 x 100 x 20 x 3mm steel flat bar 2 x 70mm x 3mm steel wire Step 2: Complete the following steps:

TYPES OF BIRDFEEDERS There are many different types of birdfeeders available from nurseries, hardware stores, co-ops and craft markets. They all fall into one of the following broad categories. Platforms, tube feeders and hoppers. Providing more than one type of feeder will increase the number of different types of birds to your garden. The feeders are best positioned on a pole or suspended from a tree, which prevents predators from worrying the birds during feeding. Platforms are ideal for mixed wild bird seed as the different species can select which seeds they prefer, as opposed to a tube feeder where certain birds will empty the feeder to get to their favourite seed. Some platforms are provided with spikes for the placing of fruit such as apples, grapes or peaches. Remember to clean the feeder regularly and disinfect with some liquid detergent, rinse well and dry thoroughly before re-filling with seed. Regular cleaning to remove old seed husks and droppings is essential to maintain the health of the birds. Should the seed get wet, wash out and dry the feeder before re-filling. It is recommended that you wash your hands after handling the feeders for reasons of hygiene.

`` Drill an eight mm hole in the centre of the 2 trays and the flower pot `` Drill an 8mm hole in the 100 x 100mm support piece `` Drill an 8mm hole in the 100 x 20mm flat bar and round the ends `` Cut the green riser pipe to the required lengths: 1 x 300mm, 1 x 250mm and 1 x 25mm `` Round the ends of the wire, bend as shown and tack weld into place -- You may require assistance for this step -- Round the wire ends, but do not sharpen, as they may cause harm to the birds

Step 3: Assemble the feeder from the bottom up following the sequence as shown A. Screw a nut about 25mm onto the rod, place the round tray, a penny washer and the support piece onto the rod and tighten up with the threaded eye When certain species become too prolific, such as doves and starlings, they fight to get to the feeder and may injure each other. The larger birds also tend to dominate a platform feeder which excludes many of the smaller birds. This is another reason to provide a variety of feeders in order to accommodate the needs of the various birds that visit your feeding station. Control the number of any one type of bird by not offering mixed seed on the ground or on platform feeders, rather use tube or hopper feeders which limits access to the feed to specific species. Certain foods are not good for birds. Avoid honey as it contains complex

Innovation

Award grows high flyers in agriculture

T

he Gryphon Corporation is an engineering and technology start-up founded in 2018 by two young aeronautical entrepreneurs, Samuel Mathekga and Clive Mathe.

The company is focused on designing and developing innovative solutions for solving economic and societal problems in Africa, and has been incubated at the Innovation Hub in Pretoria since 2018. They are currently working on creatively tackling both the large and small-scale agricultural sector through crop-spraying drones and agricultural data consultancy, advocating for datadriven farming practice. “A crop-spraying drone platform that is cheaper, more efficient and more reliable than any traditional crop-spraying platform. Traditional crop-spraying platforms include mannedaircraft crop-spraying, manual spraying and tractors,” says co-founder Mathekga.

Collects data The innovation also comes with a data-acquisition package that collects data for specialised trend analysis to help make better farming decisions in the future. “The objective for this is to adopt robust, adaptive farming methods that are in sync with the uncertain weather patterns, natural farm inputs (such as pest attacks) and the required need for increased crop-yields across Africa.” Mathe says the crop-spraying drone is an innovation because it addresses a critical need to increase food security in the region. “To do this, under uncertain climate (and other drivers of farming success) conditions, it is necessary that not only more efficient processes be adopted, but that robust and adaptive methods become part of the farming system. The autonomous crop-spraying drone, and the data-acquisition platforms address these requirements, and are one step of many in the direction of enhancing food security in the region. “A first-principles analysis of most of our farms in Africa clearly shows a lack of infrastructure in general, and this has resulted

in inefficient execution of many of the farming processes. This is not in sync with the heightened development in technology, engineering design, and the decreased cost of acquiring and deploying these. Through the right amount of synergy between technology and design, we can help leapfrog that lack of infrastructure with enhanced platforms such we are developing.” The duo believes their innovation will be a significant player in the agricultural sector in Africa. “Besides the skills training that will come along with its application, it will see farmers spending significantly less money in the crop spraying process while at the same benefitting from the efficiency it adds.” The innovation will play a role in improving food security in the region, and make African agricultural sector more attractive to investors. “With about 10% of the people in Africa under-nourished, and 30% - 40% of children’s death attributed to malnutrition, the social need is critical, both in South Africa and in Africa as a whole.”

Finalist The Gryphon Corporation was a finalist in the 2018 SAB Foundation Social Innovation Awards and received a seed grant of R200 000. The 9th Annual SAB Foundation Social Innovation Awards and 4th annual Disability Empowerment Awards are now open for entry and eligible entrepreneurs and businesses are encouraged to enter. The awards carry total prize money of more than R12 million with the winner walking away with up to R1.3 million in grant funding. The Social Innovation Awards are aimed at innovators, social entrepreneurs, institutions and social enterprises with prototypes or early-stage businesses that can solve social problems.

These products, services, business models and processes should directly address the challenges faced by low-income women, youth, people living with disabilities, or people living in rural areas. Prizes awarded range from between R200 000 and R1.3 million and are used as an investment in the innovation. In addition to the prize money, the winners will also be assessed on a case-by-case basis and

placed in a tailored programme with a specially selected business mentor. The programme is flexible and is adjusted to the needs of each winner, as mutually agreed upon by both the winner and their mentor. To date, the programme has invested in over 160 social entrepreneurs and their innovations with a total investment of more than R53 million.

Seasonal Climate Watch March to July 2019

Overview The El Niño-Southern Oscillation (ENSO) has remained in a moderate El Niño state and is predicted to mostly remain in this state throughout winter. This however is not expected to influence South Africa in the current and upcoming seasons as ENSO has little influence or its influence is not yet fully known. Late autumn (April-MayJune) and early winter (May-June-July) show confident

forecasts for above-normal rainfall conditions over the southern and south-western parts of the country. These are also the only areas that typically receive significant rainfall in these seasons. The late autumn forecasts are particularly confident due to accompanying belownormal minimum temperatures for the same areas. Furthermore, this typically indicates that there could be either

South African Weather Service Prediction Systems Ocean-Atmosphere Global Climate Model The South African Weather Service (SAWS) is currently recognised by the World Meteorological Organization (WMO) as the Global Producing Centre (GPC) for Long-Range Forecasts (LRF). This is owing to its local numerical modelling efforts which involve coupling of both the atmosphere

and ocean components to form a fully-interactive coupled modelling system, named the SAWS Coupled Model (SCM), the first of its kind in both South Africa and the region. Below is the first season (Mar-Apr-May) predictions for rainfall (Figure 1) and average temperature (Figure 2).

more intense or more frequent cold front systems that will affect the southern and south-western parts of the country. Increased number of rainfall days (greater than 5mm and 15mm) is also expected during late autumn, increasing the chances of flooding events in the area. For the rest of the county the rainfall decreases drastically, as normal, during late autumn and winter. Thus, as usual no significant

rainfall is expected during the forecasted period. With regards to temperatures, mostly warmer than normal temperatures are expected for the north-eastern parts of the country. The South African Weather Service will continue to monitor and provide updates of any future assessments that may provide more clarity on the current expectations for the coming seasons.

Multi-Model Statistical Downscaling System Seasonal Totals and Averages In an effort to improve the predictions made by the SCM, which struggles to produce reliable rainfall and temperature forecasts at a local scale, the Multi-Model System (MMS) has been implemented to statistically downscale various global forecasts, including the SCM and the Climate Forecasting System version 2 (CFSv2) administered by the National Oceanographic and Atmospheric Administration (NOAA). Below are the current three-season forecasts issued in February 2019. Three maps are shown for each season which include the raw MMS probabilistic prediction (left), the probabilistic prediction with skill masked out (middle) and the climatological average (right) for the specific season. The user is advised to consider the skill masked map (middle) as the official SAWS forecast, however, the two additional maps may be used as tools in such a case where skill for a specific area is deemed insufficient.

April-May-June (AMJ) 2019 seasonal precipitation prediction without skill taken into account (left), as well as skill masked out (middle). Also included is the climatological average for AMJ (right, in mm) calculated over the period 1979-2009.

Figure 1: March-April-May global prediction for total rainfall probabilities.

It is worth mentioning that the SCM levels of skill for the Niño 3.4 region (where ENSO information is sourced) are very much comparable to other state-of-the-art coupled models which are administered by other international centres. Therefore, the following Sea-Surface Temperature (SST) forecast (Figure 3) emanates from the SST Prediction System which is purely based on the SCM.

SRK solution will help energy roll-out in southern Africa

A

n Environmental and Social Management Framework (ESMF) developed by SRK Consulting (South Africa) for the Southern African Power Pool (SAPP) is being rolled out among Southern African Development Community (SADC) countries states to help accelerate priority electricity projects.

The framework, commissioned by the SAPP in 2016, will facilitate the screening of key power projects in line with lenders’ requirements – in turn speeding up their implementation across the sub-continent. A key obstacle to energy access in southern Africa is the quality of the existing power grids, which limit the ability of new power generation to be harnessed and distributed. The SAPP – which supplies electricity to consumers in 16 SAPP utilities and independent power producers (IPPs) – is busy improving these grids. In 2009, the SAPP had identified a number of priority projects that would improve the region’s power grids, and by 2011 many of these were found to require extra developmental work to bring them to bankability stage. In response, the SAPP Coordination Centre – with financial assistance from the World Bank’s International Development Association – set up a Project Advisory Unit (PAU) that would accelerate the implementation of these projects.

Technical specialists Among the implementation delays was a lack of alignment between the compliance requirements regarding environmental and social management in the projects concerned. One of the PAU’s first tasks, therefore, was to commission technical specialists to help prepare an ESMF, which

SABI | APRIL/MAY 2019

would act as a reference manual for the high-level environmental and social screening of projects – to strengthen the assessment, mitigation and management of risks and impacts. The ESMF would provide a solution to facilitate both alignment and compliance, thereby improving the pace of implementation of projects that extend access to affordable electricity.

holders and finalised; this was the third and final stage.

Stakeholder consultations Developing the ESMF required consultation with all relevant SAPP structures, so between June and October 2016 – and again in May and June 2018 – various stakeholder consultations were conducted; this was done through workshops, in-country site visits, focus group meetings, face-toface meetings, telephonic interviews and public hearings.

The resulting framework p r o v i d e s a baseline context for the SAPP region, SRK was awarded an overview the contract of regulatory to develop frameworks, the ESMF and and a methodprepared it in ology to identhree phases.

The draft ESMF was Kilian, partner and principal envithen presented to the SAPP stakeronmental consultant at SRK.

Providing a practical solution to the challenges faced by the SAPP utilities, the ESMF also includes a suite of tools to guide officials through the environmental and social screening, scoping, assessment, management planning and monitoring processes. These tools include checklists, examples of management plans, and lists of national, regional and international environmental and social requirements.

Report “The SAPP utilities and IPPs will be responsible for the on-the-ground implementation of the ESMF, and they will be the main users of the framework,” said Kilian. “As member utilities and IPPs are also represented on the SAPP Environmental Sub-Committee (ESC), they will report back on the application of the ESMF – to ensure alignment in the screening and scoping of priority power projects.” He emphasised that the PAU will play a key co-ordination role, and also facilitate capacity building and training among the planning, financial, environmental and social personnel of SAPP utilities. In April 2018, SRK was appointed to update the ESMF and facilitate the translation of the English report in French and Portuguese. The document has been disseminated to all SAPP utilities and independent power producers, and is available on the SAPP website. http://www.sapp.co.zw/sites/ default/files/499745_Final%20 SAPP%20ESMF%20Report_ Final_20180919.pdf

Johannesburg Homemakers’ Expo Young Designers’ challenge

P

The 26th edition of the Johannesburg HOMEMAKERS Expo, held at the Ticketpro Dome from 28 February 3 March, set the stage for over 350 expert exhibitors to share their latest home, décor and lifestyle products with discerning homeowners. The success of the show demonstrated why HOMEMAKERS Expo remains one of the leading events in the home improvement and lifestyle sector, and proved once again that it is on the cutting edge of international and local trends. The show featured an expertly curated selection of the region’s best home improvement suppliers, interiors, soft furnishings, lighting, kitchens, furniture, landscape design and more.

The Young Designers’ Challenge The Young Designers Challenge, sponsored by Vermont Sales saw students from the University of Johannesburg present their innovative multi-purpose power tools of the future. The winner this year was Shannon Botha and her Wedgit Seedling Planter. Second prize went to Moeketsi Ntladi and third prize to Viljee Steyl.

Wedgit Seedling Planter This project was aimed at creating an affordable tool that anyone could use along with a power tool, as an attachment. This innovative solution provides consumers the opportunity to only buy a single high-priced tool and use cheaper attachments to get the jobs done that would otherwise require specialized tools. This Wedgit Seedling Planter was designed to assist gardeners who are just starting out and small-scale farmers with the task of planting many small fragile plants at their optimum depth, without damaging or hurting the plant. This product attaches to a drill as a ‘bit’ making it easy for anyone to use. SABI | APRIL/MAY 2019

Climate change

Climate Change Must be part of business school learning Survey finds

B

usiness schools must make climate change an urgent part of the curriculum, according to a survey of 169 faculty experts in the Global Network for Advanced Management, a coalition of 30 top business schools – including UCT’s Graduate School of Business - in 28 countries around the world.

The experts agree that climate change poses a material risk to businesses, which, respondents say, must take action on climate risks regardless of government policy. Nevertheless, most estimated that global carbon regulation is achievable by 2030. Commenting on the survey results, David Bach, deputy dean at the Yale School of Management, said: “Top business school professors from around the world send two messages loud and clear: first, the climate crisis is here, and both businesses and business schools must adapt now; and second, there is no single policy solution, business approach, or MBA course that will do the trick. “What we need instead is broadbased, real-time experimentation, and rapid learning about what works and what doesn’t. Crosspollination is key, and the Global Network was designed precisely to support such efforts, connecting business leaders, scholars, and students worldwide.”

Most serious business issue A decisive 93 percent of Global Network faculty members think climate change poses a material risk to business across sectors.

40

SABI | APRIL/MAY 2019

“Climate change, possibly with air pollution, will be one of the most serious business issues, at least in Korea and China, within the next few years,” commented Namgyoo Kenny Park, Associate Dean, Seoul National University Graduate School of Business, South Korea “Climate change was once the concern of climate scientists, activists, and lobbyists. Now, it’s integrated into every field of work. Climate and health, agriculture, energy, urban planning, policy making—it’s crosscutting. To lead a successful business, you have to be aware of global shifts and risks—and you have to be a leader in shaping rather than surviving hot trends (pun intended!), said Teresa Chahine, Sheila and Ron ‘92 BA Marcelo Lecturer in Social Entrepreneurship, Yale School of Management, United States The faculty experts expressed strong positive support for companies incorporating climate risk when making decisions about investments, innovation, relationships, and talent acquisition. More than 70 percent of the experts say that companies should incorporate climate change into business decisions; there is significant concern about the sustainability

of physical operations and supply chains.

Carbon tax Sixty-nine percent of the respondents consider a global carbon tax the most effective tool to influence business decision-making on climate risk, though only 19% said they “strongly agree.” When combined with the other survey results, these numbers suggest that regulation is not the complete picture when it comes to climatechange mitigation as it affects global business. Still, experts are optimistic that a worldwide carbon tax is indeed achievable, with most respondents estimating such a tax is likely by 2030. Close to zero respondents think that a carbon tax will never happen. The majority of Global Network faculty believe a carbon-neutral economy is achievable by 2050. Close to zero respondents think that a carbon-neutral economy will never happen. “Underdeveloped and developing countries should receive compensations for carbon reduction from developed countries who took advantage of growth without consideration of climate impact,” said Andrés Ibáñez, Professor of Marketing, Pontificia Universidad Católica de Chile School of Business, Chile.

Business must step up Interestingly, 86 percent of the experts surveyed agree that businesses cannot depend on governmental action to slow climate change. “In an ideal world, our governments, under an organized global umbrella such as the U.N., will come up with practical systems to control and curb greenhouse gas emissions. While we wait for that desired date, when all governments act together, it is up to individuals and businesses to come up with a solution and avoid the point of no return. Schools around the world have a fiduciary responsibility to help with raising awareness and teaching future managers to care and take more action than our and previous generations did,” Majid Ghorbani, Renmin University School of Business, China.

Should be incorporated In an overwhelming show of thinking, professors at top business schools agree that climate change and its impact on business and society should be incorporated into the core MBA curriculum. Interestingly, the survey responses on how to achieve this span a wide spectrum—from emphasizing the risks of climate change to discussing its opportunities, indicating that business students should learn a balance of climate-driven risks and rewards for businesses.


Climate action

Cyclone Idai disaster Focus needed now To protect the vulnerable

C

yclone Idai and the human tragedies it wrought is “yet another alarm bell about the dangers of climate change” UN Secretary-General António Guterres warned - in the days following the worst cyclone devastating the lives of more than a million people in Mozambique, Zimbabwe and Malawi - that vulnerable countries, would be hit the hardest unless urgent action is taken by nations across the world.

People clinging for dear life to treetops waiting for rescue helicopters, cows wading along with their heads just above water and a sobbing woman with a chicken under each arm, probably her main material possessions – the sad media and drone images following Cyclone Idai were heart breaking. People with little in the way of worldly goods – very vulnerable communities – so tragically affected by a massive tropical cyclonic storm. Entire villages were reported to have “washed away” in some areas. Sadly, the same old story: the most vulnerable suffer badly when natural disaster strikes.

The terrible consequences of Cyclone’s Idai were due to a number of factors said the esteemed journal Nature. The combination of very concentrated rainfall, low lying land and poorquality housing and infrastructures made Cyclone Idai one of the Southern Hemisphere’s deadliest storm. The tropical cyclone made landfall in the Mozambican city of Beira on 14 March and the flooding caused by the storm displaced thousands of people and some 1.85 million people have been affected so far

in Mozambique alone, the United Nations estimated.

Revved up climate action “Such events are becoming more frequent, more severe and more widespread, and this will only get worse if we do not act now”, said the UN chief. “In the face of turbocharged storms, we need revved up climate action”, he added, addressing correspondents at UN Headquarters in New York. The Secretary-General convened a Climate Action Summit in September, to try and mobilize countries around the urgent need to reduce global warming to well under 2 degrees Celsius above pre-industrial levels, in line with the 2015 Paris Agreement. An estimated three million have been affected in the three coun-

Call for South African business to assist Business Unity South Africa (BUSA) called on business to enjoin the humanitarian efforts currently underway in the Southern African Development Community (SADC) following the devastating effects of Cyclone Idai. Parts of SADC States Malawi, Mozambique and Zimbabwe have been left devastated in the aftermath of the cyclone. On behalf of business in South Africa, BUSA extended its sympathy to all those affected. BUSA said it acknowledges the Government’s speedy and appropriate response to the crisis and commends the various rescue and humanitarian efforts by South African organisations and actors.

“We know that some relief has been provided by South African companies that have operations in these countries. This moment calls upon all of us to lend our support to the humanitarian efforts currently underway, however small,” said BUSA President Sipho M Pityana. BUSA encourages Members to support these humanitarian efforts: be it through financial donations or in-kind contributions, as advised by the various agencies on the ground. BUSA advised that donations of items and goods, including clothing, food and water, may be made to the Department of International Relations & Co-operation (Dirco) in Pretoria.

tries, nearly two-thirds of them in Mozambique, where key port city Beira was “practically razed to the ground” while the farmland interior has been inundated, said Mr. Guterres. At least a million children need “urgent assistance”, and “we fear that whole villages have been washed away places we have yet to reach”, the UN chief added, with reports that $1 billionworth of infrastructure has been destroyed. He said citizens of the three southern African nations would need “strong, sustained support”. The UN launched a launched a $281.7 million revised flash appeal for Mozambique, designating the disaster a “scale-up emergency”, which is the most severe: “I call on the international community to fund these appeals quickly and fully so that aid agencies can urgently ramp up their responses”, said Mr. Guterres.

Sonkrag en elektrisiteit

Landbou kan binne een jaar die oplossing vir beurtkrag bied Agriculture says it has the solution to load shedding within a year

I

n short: Agri SA says its members has the potential to supply the electricity needed to prevent future load shedding through solar power generation. There are already 500 applications for solar generation plants, that have the potential to contribute 1 400 MW to relieve strain on the grid. If the administration processes are streamlined, these 500 applications and others can be rolled out. “We are not asking for funding or even special treatment, just to speed up the process within Eskom and NERSA to process these applications,” said Nicol Jansen, Agri SA chair of the Centre for Excellence: Economics and Trade. “This is a win-win opportunity for government and South Africa.” Agri SA sê sy lede het die vermoë om elektrisiteit deur sonkragopwekking te verskaf, wat nodig is om toekomstige beurtkrag te voorkom. Daar is reeds 500 aansoeke vir sonkragopwekkingsaanlegte, wat die potensiaal het om 1 400 MW by te dra om druk op die kragnetwerk te verlig. Indien die administrasieprosesse gestroomlyn word, kan dié 500 aansoeke en ander uitgerol word. “Ons vra nie om befondsing of selfs spesiale behandeling nie, net om die proses binne Eskom en NERSA te bespoedig om

hierdie aansoeke te verwerk,” sê Nicol Jansen, Agri SA se voorsitter van die Sentrum van Uitnemendheid: Ekonomie en Handel. “Dit is ‘n wen-wen geleentheid vir die regering en Suid-Afrika.” Kleinskaalse sonfotovoltaïese (PV) installasies bied ‘n geleentheid vir boere om elektrisiteit op te wek en druk op die kragnetwerk te verlig. Ongelukkig is slegs 13 projekte tans gekoppel en in bedryf, weens Eskom se stadige verwerking en administrasie van aansoeke, asook die stadige implementering

van elektrisiteitsregulasies en die bottelnek om by NERSA te registreer.

Bespoedige prosesse Indien Eskom en NERSA hul prosesse kan bespoedig, kan hierdie aansoeke (meestal van boere) 1 400 MW genereer wat fase 1 beurtkrag kan verhoed. Verder kan die landbou dié 1 400 MW potensiaal meer as verdubbel, indien kommersiële banke bereid is om sonkragsentrales as sekuriteit te gebruik om toegang tot kapitaal te verkry. Tans benodig banke bykomende sekuriteit om hierdie projekte te finansier, wat deelname aan projekte beperk. “Deur die regulatoriese en administratiewe beperkinge te verwyder en die gebruik van sonkraginstallasies as sekuriteit vir befondsingsprojekte, kan boere potensieel met verdere uitbreiding genoeg elektrisiteit verskaf om fase 3 beurtkrag te verhoed,” sê Jansen.

Private public collaboration Releases 4.4 billion litres more water per year

W

orking in collaboration with local municipalities in Cape Town and Tshwane, SAB has managed to help provide a total 4.4-billion litres of additional water per year for use by residents in those cities.

All-electric KIA debuts in Geneva

e-Soul

new KIA e-Soul brings long-range, zero-emissions Tsoldhepower to the urban crossover class. The third globallyelectric vehicle from KIA Motors makes its European debut at the 2019 Geneva International Motor Show.

In its third generation, KIA’s pioneering urban crossover has become more distinctive, dynamic and innovative than ever. While the e-Soul embraces the iconic design and playful character of its predecessors, it will be powered in Europe exclusively by electric energy, with a choice of two long-range, zero-emissions powertrains. The new-generation battery packs powering the new e-Soul are up to 30% more energy efficient than Europe’s current best-selling electric vehicle. Emilio Herrera, CEO for KIA Motors Europe, commented: “Since its inception, the Soul has been a true pioneer for KIA, and for the wider market. A decade ago, it established the urban crossover segment, and when we launched the Soul EV it became the first fully-electric crossover. The new e-Soul breaks more ground, as we launch it in Europe with an extended-range electric powertrain as standard – without the option of an internal combustion engine. “The market has changed significantly in recent years, and in 2018 – the outgoing model’s final year on-sale, KIA sold more of the zero-emissions Soul EV in Europe than petrol and diesel versions combined. KIA is recognised today as a global leader in electrified vehicles, with a growing range of mild-hybrid, hybrid, plug-in hybrid and electric vehicles. Electrified models accounted for one in eight KIA cars sold in Europe in 2018, up from one in 10 in 2017, and the new e-Soul will further build on this momentum.” The e-Soul retains the strengths that have characterised earlier generations of the model, offering outstanding value for money, a roomy interior for five occupants, and high levels of space and versatility. The new e-Soul goes on-sale across Europe towards the end of the first quarter of 2019.

SABI | APRIL/MAY 2019

Powertrains and zero-emissions The new KIA e-Soul will be sold in Europe exclusively as an electric vehicle, with a choice of two fully-electric, zero-emission powertrains to meet the needs and budgets of different customers. Drivers have a choice of longrange (64 kWh) and standardrange (39.2 kWh) powertrains. Whichever version a buyer chooses, both variants offer vastly improved range over the outgoing Soul EV. On-road performance is also enhanced, with significantly more powerful electric motors providing 395 Nm of torque – 39% more than before. Furthermore, KIA’s newgeneration lithium-ion polymer battery packs offer greater energy capacity than those of many other electric vehicles, regardless of price. Cell energy density of 250 Wh / kg, achieved through new cell chemistry, enable the cells to store 25% more energy within a defined volume than those of the 200 Wh / kg battery pack in the outgoing Soul EV. This has enabled KIA to keep the battery pack as compact and lightweight as possible, while taking a huge leap in the car’s zero-emissions driving range compared to its predecessor and other electric vehicles on the market.

The long-range 64 kWh battery pack is paired with a 150 kW (204 ps) electric motor, enabling the e-Soul to travel up to 452 kilometres (280 miles) on a single charge (on the WLTP combined cycle). Energy consumption for the 64kWh battery pack is just 157 Wh / km on the WLTP combined cycle – 24% more efficient than Europe’s current best-selling electric vehicle. Energy consumption for the long-range e-Soul is as low as 109 Wh / km in urban environments (WLTP urban cycle). With the powertrain’s maximum 395 Nm torque available from a standstill, and 84% more power than the car it replaces, the long-range 64 kWh e-Soul will accelerate from 0-to-100 kph in just 7.6 seconds. The standard-range 39.2 kWh battery pack powers an efficient 100 kW (136 ps) electric motor. With peak torque of 395 Nm, and 23% more power than the outgoing Soul EV, the significantly improved efficiency of the battery nevertheless enables the standard-range e-Soul to travel up to 277 kilometres (172 miles) on a single charge. Energy efficiency is rated at 145 Wh / km (WLTP combined), 30% more efficient than the best-selling electric car in Europe – making it one of the most energy-efficient electric vehicles in the world. A Combined Charging System (CCS) DC fast charger is fitted as standard to both models, enabling shorter stops for charging. Both battery packs can be recharged

from 20% up to 80% capacity in just 42 minutes from a 100 kW DC fast-charger.

Energy-recuperation The e-Soul is fitted with a range of energy-recuperation technologies to maximise driving range. This includes KIA’s energy efficient heat pump system, which scavenges waste heat from the car’s coolant system. It also features KIA’s innovative individual ventilation and air conditioning system, which shuts off cabin ventilation at the source to all seats except the driver’s – unlike other systems, which merely divert air to open passenger cabin vents. The e-Soul is also equipped as standard with KIA’s innovative regenerative braking system, operated by paddle shifters behind the steering wheel. The system provides drivers with the ability to slow the car and recuperate kinetic energy to maximise its driving range and efficiency. Drivers can choose from five regenerative braking levels (none, 1 to 3, or ‘single pedal’ mode), depending on the level of energy recuperation they desire from the brakes. The system’s ‘single pedal’ driving mode also allows the car to harvest the maximum amount of energy from its brakes, and even enables the driver to bring the car to a gentle halt without necessarily needing to push the brake pedal. The regenerative braking system can also automatically adjust the braking level if it detects the car in front slowing down, creating smoother coast-down driving – especially on a steep downhill road. A Smart Eco Pedal Guide display on the driver’s instrument cluster also keeps the driver aware of real-time battery usage based on accelerator pedal input. In addition, the e-Soul’s Drive Mode Select system lets drivers adapt the car to their preferred style or the road conditions. Drivers can choose from ‘Normal’, ‘Eco’, Eco+’ and ‘Sport’ mode.
