Long-term, sustainable impact on water security, learning, and capacities for vulnerable communities in Maldives

FP007: SUPPORTING VULNERABLE COMMUNITIES IN MALDIVES TO MANAGE CLIMATE CHANGE-INDUCED WATER SHORTAGES
Partner: United Nations Development Programme (UNDP)
GCF financing: USD 23.6m
Total financing: USD 28.2m

By constructing decentralized and integrated freshwater supply systems that use rainwater harvesting and filtration combined with reverse osmosis desalination plants, this Green Climate Fund-backed project aims to bring reliable year-round freshwater to 25 outer islands in the Maldives. This increased water security by reducing local reliance on transported water had also lowered plastic pollution by 50 per cent.

The project reduced the number of targeted islands from 49 to 25 due to overly optimistic estimates during design, upgrades in integrated water resource management technologies, increasing costs under the COVID-19 pandemic, and other implementation snags. Yet the project reached the number of beneficiaries it had originally planned, with scalable interventions and indications of paradigm shift in the sector. Some activities exceeded initial expectations (e.g. knowledge sharing, learning, capacity development). It will take time to realize the full effect of these efforts, some of which are not possible to measure during project implementation. For example, many of the groundwater recharge activities will be hard to measure until years into the future.

The project developed and initiated a strategy to transfer ownership of integrated water resource management systems to utility operators. Ten of these systems have been transferred to one of two state-owned utilities. GCF supported initial investments, but later investments in operations, maintenance, and monitoring by utilities will be necessary for lasting impact and paradigm shift in the sector.

Climate-sensitive integrated water resource management designs are now being used in communities across Maldives, and the project contributed to greater awareness and capacities among government entities, especially the Water and Sanitation Department in the Ministry of Environment, Climate Change, and Technology. Groundwater studies carried out by the project were the first of their kind and will inform future water investments and activities.
