APPROACH AND METHODOLOGY
Tonga Community Development Trust is an indigenous non-government organization working with communities in Tonga since 1978. The Trust has a long history of engaging communities in a participatory manner.
Tonga Community Development Trust's mandate is to assist vulnerable families and communities to ensure they have access to good quality drinking water by building their resilience and capacity to adapt to the impacts of climate change.
A baseline survey will be conducted to collect information on the current situation of rainwater harvesting systems among the Amatakiloa members, paying particular attention to how many households have damaged water tanks and how repair costs. The data collected will be used to develop a priority list for the project and will be based on vulnerability and income levels. The baseline information will be instrumental in monitoring the impact of the project has made on the Amatakiloa Women's Group.
A sustainable rainwater harvesting workshop will be held to engage Amatakiloa group members in learning and sharing lessons about the importance of using rainwater wisely and ways to protect drinking water from contamination. The workshop will train participants on simple technique of using H2S water testing to identify the quality of water and appropriate follow-up actions.
Repair and maintenance of water tank: Tonga Trust will cover the cost of repairing the systems and purchasing materials, such as cement bags. Participants will provide labor and food while carrying out the repairs.
Tonga Trust will conduct ongoing monitoring to ensure that the project is carried out accordingly to plan. An evaluation will be conducted halfway through implementation to provide lessons learned for further improvement and to monitor achievement of project goals.
Tonga Trust will continue to seek further funding to support the continuity of the project into the next phase, especially providing support for low-income members without water tanks.

Being one of the independent, small island developing states in the vast South Pacific Ocean, Tonga is vulnerable to the impacts of climate change due to its relatively small size, island features, geographical location and limited natural resources. There are only two sources of water resources in Tonga - groundwater and rainwater. The impacts of climate change have led to more contamination of groundwater by seawater, as well as increasing uncertainty in the weather and rainfall patterns. In addition, increased population growth is putting pressure on existing supplies. A recent survey on the rainwater catchment system in the outer island has shown that many household systems are not adequate to meet household demand in the event of a major natural disaster, such as a drought or tsunami. One of the primary problems is the maintenance of damaged cement tanks due to cracking from earth movements and earthquakes. In addition, many households do not own a water tank and have to fetch water from neighbors or communal institutions, such as schools, churches or village halls.
