SUBMITTED BY Yunqian Zhan s3715790 RMIT UNIVERSITY School of Architecture and Design Master of Landscape Architecture Design Research Project 2020 COURSE COORDINATOR Alice Lewis Jen lynch TUTORS Alban Mannisi Nov. 2020
ABSTRACT Pacific Island cities are at the front line of climate change and are facing the highest rate of urban population increase from the past century. Groundwater is the primary freshwater resource for islanders is threatened from seawater intrusion due to the sea level rise. The hydrological changes imply significant risks for society as inevitable consequences of future change require landscape architecture to stay abreast of consideration from social and ecological factors. The marginalized communities of Honiara in the Solomon Islands have complained about low water quality and inadequate water supplies for sixty years. However, there is a little solution in sight except for over-exploiting groundwater which accelerates freshwater contaminated as Honiara continues to grow. This project investigates the role of landscape architects as leaders and communicators. In the short term, provide alternative water resource and reconstruction of the site by introducing traditional cultural. In the long term, while improving the ecological environment and rebuild the existing tourism ecological assets. Relink the disconnection between Malaita settlers and Guadalcanal locals. Through combining asset-based community development, design activism, and ecological design to alleviate freshwater-related problems and raise awareness of people’s water use difficulties in marginal areas. Following a comprehensive analysis, voice identity and culture background of the population should be taken into consideration to build the relationship between the environment and the inhabitant. Beyond tangible and technical proposal, by acknowledging the construction of the environmental crisis through community sustainability. An adequate response to resolve the water supply and improve the quality of life for the community of Honiara.

0.1 INTRODUCTION Small remote islands are the front line of climate change impact, urban expansion and finite resource crisis(Wong et al. 2014). In the Pacific Ocean, Solomon Island comprises six major islands and nearly 1,000 smaller islands that are environmentally and economically vulnerable, because of water resources limited due to social and environmental constraints (SOPAC, 2007). The insufficient cover of sanitation and waste service contaminate the surface water resource. Sea level rise makes the community more susceptible to freshwater contamination, seawater intrusion and flooding. The marginalized community who live in informal settlements zones are facing water shortage problem and have constrained access to sanitation infrastructure. The case study area is Honiara, the capital city of Solomon Islands. It located on the northwestern coast of Guadalcanal with 84,520 people are living in here. Honiara also has a large Peri-urban region where most immigrants settle in ISZ (informal settlement zone) which are minimally serviced. In the long term confrontation between water shortage and urbanism in Honiara, overexploitation groundwater will increase saltwater intrusion rate, which can cause groundwater contamination, ecological damage and people’s health problems. Water and sanitation deprivation linked to violence against women. Women and girls are vulnerable to rape and sexual harassment when they have no option but to walk considerable distances unaccompanied. Therefore, the city urgently needs an ecological sustainable ethic strategy
for resilient water use. Intervention strategy will carry out in cooperation with Honiara city council, Solomon Water, NGO Vois Blong Mere Solomon and the local community. The goal of the project is to control the surface water pollution source, water use efficiency and improve human well-being and ecological health. During the process, three UN sustainable development goals will be gradually achieved, which is clear water and sanitation, reduce inequalities, and sustainable city and community. In this project, multiple design techniques will be applied across different scales. In recognizing the agency of residents in shaping their environments of habitation and engaging in the project, residents are presented with options for levels of labour investment. Low investment for the household collects water and waste. Medium investment for the community sanitation facility. High investment for the coastline ecosystem urban space. Promote traditional cultural-educational board, cooperate with local NGOs and develop local tourist assets. Those interventions are relinking methods to repair the historical ethic tension between migrants settlers and Guadalcanal local people. By promoting the acknowledgment and respect of physical assets and social assets with the community, the ecological system plays a crucial role in the network function.

‘‘Every year, we are told that it is the hottest since the first weather recording stations were set up; sea levels keep on rising; the coastline is increasingly threatened by spring storms; as for the ocean, every new study finds it more acidic than before. This is what the press calls living in the era of an ‘ecological crisis.’’’ - Bruno Latour

Sea level rise(SLR) is a major concern for many low-lying islands. It will affect the availability and distribution of water resources. Seawater/freshwater interface will move inland and decrease the investments of groundwater available (UNESCO-IHP/UNEP, 2016). Moreover, the impact of water shortage also directly through risks for socioeconomic aspect on the ecosystem, energy, food security and economic. Water management is crucial for climate-change sustainable development.

1.1 The tensions The Solomon Islands are suffering from environmental injustice. The whole country’s carbon emissions account for a small proportion of the world, but it has suffered the worst consequences of climate change. Sea level rise causes the shoreline recession in the Solomon Islands. Five islands had vanished, and its effect the inner movement of migrant communities into urban and peri-urban areas from neighbouring islands. As a result, capital cities Honiara, face threats of environmental hazards as they grapple with the lack of adequate infrastructural services (ESCAP 2019).

1.1 The tensions Why people move into Honiara? Mostly migrants are indigenous from the other islands. Malaitans are the largest group of inward migrants (Report on Migration and Urbanisation. 2009). As the effects of climate change intensify, several islands have already been submerged. These islanders are climate refugee, have no options but to seek another place to live. City as Honiara as their destination. Another purpose of interprovincial migration is to obtain employment, receive higher education and receive better medical treatment and enabling political participate.
What the impact of inter-provincial migrants to Honiara? Population growth and increasing rural-urban migration have resulted in housing pressure and growth of these informal settlements in urban edges. Low and middle-income earners are lack of usable land to drive these trends. Another challenge is limited or no access to infrastructural services. Just over two-thirds of households have piped drink water in the Honiara urban area, but very few have this in the urban edges. These issues have increased inter-ethnic tensions. The ethnic tension escalated in December 1998 when the Guadalcanal Revolutionary Army, also known as Istambu Freedom Fighters, started an offensive of active intimidation against the Malaita settlers, resulting in a mass dislocation of people (Beest, D. van., 1999).

1.1.3 Honiara Existing Water Supply Condition Four boreholes as the main water supply for Honiara urban context. The service area for water supply extended outside the town boundary. However, the service area for sewerage is limited inside the town boundary. Due to the topography, 25% of residents in Honiara are suffering low water pressure problem. Some of the residents can not get any water during the peak demand hours in the daytime. With increasing pumping the groundwater policy, the speed of saltwater entry into Honiara aquifer will be increased and make groundwater contaminated.

Alternative water sources By adding more water resource facility for the community. For example, rainwater catchment reclaimed wastewater and stormwater. In order to reduce the existing well water supply pressure.
Connection non-reticulated water supplies Non-reticulated water supply is any supply that is not piped to a business by a water utility or local government. For those area does not have access to a reticulated or town water supply. Increase the accessibility to the nearest safe water source.
Protect water source from contaminating Water contaminated include seawater intrusion, solid waste in the river or sea shore, waste outfall or water pull into the water resource.

1.2 Scoping resource The government in Solomon island proposed adding more boreholes which are standard water-resource management (JICA 2006). This strategy helps relief water shortage by expanding the service area in the short term. However, these are not sustainable management, especially for the coastal island. Accelerate saltwater intrusion into aquifer layer contaminated groundwater. Reduce water in the recharge area such as reservoir and stream. Lead land subsidence in alluvium geology layer (Usgs.gov). Expansion of the flooding influence area. The existing service area still limited to reach the ISZs (informal settlement zones) thoroughly, where the people in there are still far from the piped water and boreholes. Moreover, the alternative water resource for ISZs is necessary.

1.2.2 Alternative water resource There are four primary water resources in Honiara. Include piped water, boreholes, river and rain tank (JICA 2006). Extreme rainfall in Honiara during November to March has a huge potential resource for water reuse (Nicholas et al. 2016). Harvesting and retaining stormwater on the riparian for public water reuse. Collect the surface runoff water for household water reuse. Make great use of rainwater as an alternative resource.

1.2.3 Conservation crisis - riparian Security of water sources is essential to protect water sources from people contaminating the water sources in Honiara as well as in the water supply to their residences. Being a major river system in Honiara, the Mataniko River contributes significantly to river-derived ecosystem services in Honiara. The river plays a key role in the provision of aquatic food and domestic water use. Site along the Mataniko river has been polluted from excessive disposal and solid waste by residents. Use GIS weight overlay function between population density and stream density to speculate the waste density along the Mataniko river area. The main reason causes the waste problem is the lack of sanitation infrastructure and waste collection.

1.2.4 Conservation crisis - coastal In addition to the conservation crisis of water resources caused by human-made reasons, natural disasters will also pose a threat to water resources and ecological environment. Hurricanes will destroy vulnerable informal settlement zones. Therefore, the early warning system is needed to enable people to take refuge early. Sea level rise and coastal flood will also aggravate groundwater pollution. It is essential to reduce seawater intrusion and protect groundwater. The sea level rises to a certain level will submerge some buildings. During the long term evacuation process, some artificial or natural barriers are needed to block the seawater, and protect and provide ecological habitats which will be affected in the future.

1.3.2 How to improve quality of life for ISZs? The arc of the landing analysis indicates the disconnection of the marginalized community and urban centre. This disconnection not only depleted the nature resource but also of human well-being and quality of life. To achieve sustainable planning and reactivated the ISZs, it is necessary to understand the whole bioregional system and thinking. Local, regional, cultural, political, ecological and economic are woven into together and interconnected.

Connection DESIGN ACTIVISM: These designers and planners use design as a tool of social action and transformation. And is a method that promotes a vigilance that is required to transform participation of the voiceless and faceless (Dean, Andrea Oppenheimer, 2001) 31
Along with Design Activism, there is a need to understand a key concept in the field of Community Planning and Development, and that is Asset- Based Community Development, also known as ABCD. (Kretzman & McKnight, 1993)
ASSET-BASED COMMUNITY DEVELOPMENT is to exchange the typical focus on needs and deficits of a community, and replace it with a list of all the assets present in the community and vital to its development. The outcome of this more positive approach is that the community then becomes aware of its capacities, skills, strengths and empowerment. (Kretzman and McKnight. 1993)

People’s SENSE OF PLACE along with its correlation to an improved sense of well being, to a sense of mental and physical restoration, to enhanced quality of life, and an improved sense of stewardship—are all part of understanding of sense of place. These ideas are all part of the multi-dimensional meanings of sense of place. (Steele, 1981)
SENSE OF PLACE can be defined in relationship to a built environment considering the greater natural environment of place. (Stedman, 2003) 32

CHAPTER STATEMENT In this chapter, Asset-based Design approach will be used to analysis of the space. The bioregional thinking is essential called to address the missed opportunities of the land and reactivate non- integrated community of obvious and concealed character. The history of land reveals the cultural heritage, skills for problem solving and women networks of mutual support. Indigenous knowledge to forecast the climate to let community prepare for the disaster. Land-use change from colonial directly impacts the vegetation degraded, especially coastal vegetation. This area is an opportunity for environment builder to reinforce economic landscape.

The modern women’s groupings in the Solomon Islands can be traced back to the first settlers on the island shores. In several areas, women organized themselves into groups for work, recreation, and ritual activity long before traders, missionaries, and colonizers arrived (Pollard, A.A. 2003). As neglected potential social assets, women’s grouping can provide important vehicles for social organization and action. They contributed to the education of their children. They know more about soil and forest their garden increase home income. They also know the knowledge related to health and about indigenous methods in local treatments for disease.

The Blue Water tree loses its leaves before dry season begins (Plotz et al. 2013).
Restore coastal ecosystem provide habitat for marine plants and animals
Turtles lay eggs amongst trees before cyclone season (Chambers et al. 2013).
If the Anakwae is flying and return to the sea that tells us that the sea is fine and that it will be a fine nice day for sea travel and fishing (NDMO,2017).
If the sea birds called Anakwae is stand at the sea shore, that tell us the outside of the sea is not good and conditions are not favourable to do fishing (NDMO,2017).

2.1 Social capital Indigenous knowledge from Malaita settlers passed orally from generation to generation. They are sing behaviours of plants and animals to predict the weather. This knowledge remains useful for the disaster preparedness for today.
when a group of Frigate birds are flying onto the sky it means there is a storm coming after 2 - 3 days or after 1 week (Fanega 2018).
There is a tree called the Rara tree, during the months of April to May, the tree flowers and when its flowers fall completely to the ground, rain and wind will come two weeks after. The Rara tree is remind us that rainy season is near (NDMO,2017). Vines (betel nut) If the leaf dies , from all the sun it indicates rain will come soon (Fanega 2018).
Blue water tree and Rara tree can be plant along the river to let people know when the dry and rain season are coming. And provide habitat for Frigate birds. Education board

2.2.1 Ecosystem link - Forest life and deforestation Solomon Islands are one of the most biologically rich archipelagos on earth. Larges number of animals and plants found there are endemic, meaning they are found nowhere else on earth. These species are close link to the cultural, livelihood and people well-being. However, the deforestation caused by human activity, logging and land-use change harm the environment. We should provide valuating ecosystem service in the coastal area, urban green space and river to input value for economical purpose.

2.2.2 Economic link - Tourism assets Unique natural view and diverse flora and fauna attract many foreign visitors to Honiara to enjoy the natural beach beauty and go diving. Expect that, there are lots of opportunities to peek at Solomon Island’s cultural heritage. Melanesian cultural festival and Spear Dancing Festival displays variously experienced throughout the year. As well as local experience life, vendor market at the park can provide local tourism food and opportunity to communicate with local people. Sustainable economic activity can provide employment and income in both urban and rural areas. The strategy is focus on a limited number of areas that have high tourism potential and existing tourism products.

CHAPTER STATEMENT This chapter shows the iteration of the design techniques to achieve three goals. Firstly, Harvesting and reusing rainwater, greywater and wastewater through rain gardens, phytoremediation, roof tank and permeable alleys. Secondly, rebuild resilient public parks at the riverside abandon area and coastal zone to mitigate the impact of natural disasters. The function of the resilient parks has rainwater collector and infiltration, create new habitat areas, provide sanitation area, education area and play area. Finally, the social link for the neighborhood help and warning climate disaster. Center speaking area as the place for the NGOs to hold voluntary meeting. Planting program help restore coastal ecosystem and boost local economic.

3.1 Reuse Water harvesting + Water purification What the source of water can be collect and reuse? 1.Stormwater, precipitation and run-off. Honiara rainfall is driven mostly by the West Pacific Monsoon during the wet season from November to April. The monthly average rainfall is about 250mm in the monsoon. 2. Treatment of greywater – typically combined with wastewater, but this can sometimes be separated and reused.
What is low, medium and high investment? In acknowledging the agency of residents forming their environments of habitation as well as the existing living systems, residents are provided with options for levels of investment within the pooled water and reuse process.
Where to carry out water collect and reuse process? From two different scale, low investment means the household scale which needs the family member as an actor and labour for recycling and reuses water process. The medium investment represents the community scale.

3.1.1 Low investment Technique for water harvesting Collect and reuse of rainwater on-site by passive and active approaches. Active approaches include the capture and retention of runoff generated by roofs and tank. Residents can store water and used to supplement water supply during drier periods. Passive approaches include prepare of organic soil that collects precipitation and runoff in planting bed. These water can be collected, bio-filtered and absorbed by plant root cleansing off residue and other toxic. These gardens retain and infiltrate rainwater during wet periods, but dry out after the monsoon ended.

3.1.1 Low investment Indigenous methods water purification For Indigenous peoples, especially women, respond to protect and nurture water. Water is not only for drinking but also has traditionally been used in agriculture, to grow medicines, and for cleansing. The result of colonization has led to a disconnect in the intergenerational transfer of knowledge surrounding water (Kate C. Shianne M., 2016). Improving drinking water quality at the household level is essential to draw attention to water issued faced in a marginalized community. Moreover, exposing the inequities in the involvement of women in water governance. Many technologies have been developed to treat wastewater. High-cost maintenance makes it unable to implement in developing countries in the short term. However, nature has an astonishing way to rejuvenating itself. Indigenous knowledge indicates that several plant species can be used as a coagulant and disinfectant for water treatment (Megersa et al. 2014).

REFLECTION THE GAP IN RESEARCH The age range of interviewees is limited. Therefore, we cannot hear the attitudes and voices of all ages on social injustice. Transformational Honiara: looking through the lens of water takes landscape architecture as a leading potential to explore how landscape design can integrate with the complex socioecological condition with a new transforming design framework. The project framework is based on the sense of place, focusing on the value of asset-based design and the experiment of design activism. However, in the construction process, the project relies mostly on the cooperation of local sponsor groups and the government. Therefore, Transformational Honiara: looking through the lens of water lacks a level of specificity necessary to claim that the proposal would succeed confidently. The assumption has been made in the degree of public participation for better articulate the ambition. For the cooperation and coordination of city stakeholders and NGO, more specific strategies and follow-up cooperation are needed. For example, the investment in water recycling in ISZs and whether the residents are willing to participate in it will determine the success of the project. In this regard, there is also a lack of project introduction to the local people. In the preliminary analysis, according to the previous JICA data, the residents’ enthusiasm for water reuse and optimization projects is very high. At the same time, the measures are taken by the Environmental Health Department also need to be followed up in the later stage, such as building water-friendly toilets and optimizing the garbage collection system. In the implementation phase, other disciplines
cooperate to re-examine the possibility of reusing local materials. Thus, Transformational Honiara: looking through the lens of water for landscape architecture as leadership potential, as a research framework for water resources issues and ecological health in marginal communities. SCOPE AND LEARNING Through the Transformational Honiara: looking through the lens of water, my opinion towards Landscape Architecture has shifted. During my project A, I think the advantage of Landscape Architecture is to bring a series of intellectual approach. There is no doubt that functional and engineer design can solve a real-life problem. Over the past years, I have become genuinely convinced that there an urgent need for the creators of built environments to act responsively and justly. Landscape architecture inherently responds to human conditions and ecological systems. In the process of exploration, projects for the most disenfranchised communities need to value the knowledge of cultural and social. Water and sanitation pose the greatest obstacle to a sense of ownership by the communities and sustainable interventions. Lack of prior knowledge about indigenous peoples’ beliefs and values related to water, sanitation, health and hygiene helps explain a large part of the failures of many interventions. Through this project, it informs me as a future practitioner, instead of solve and fixes the problems, Landscape architecture, at is core, always needs to respond to nature within ecological and social parameters.

5.4 Acknowledgment
Throughout the completion of project, I have received a lot of help and assistance that allowed me to arrive at this outcome. I’d firstly like to thank my family and all my friends for their unrelenting support that help me grounded even in the most stressful years. I’d also like to thank Ata Tara for his support and share the valuable information, which helps me start my project by familiar Honiara as the site. And I would like to thank Kyle Bush for giving me clear and specific advice after project A, that help me re-established the theory and transform the research direction for this project. Finally, I’d like to thank my supervisors Alban Mannisi always give me constructive advice, and for pushing me to think differently about my work and shaping the way I approach design, helping my project to take shape throughout the semester.
