UNICEF Indonesia, the Water Resilience Coalition and the CEO Water Mandate, working with Indonesia's Ministry of National Development Planning and subnational government, announced on 24 August 2026 the launch of BERSAMA, an initiative aimed at strengthening water resilience and expanding access to climate-resilient water, sanitation and hygiene services in the Citarum watershed, West Java.

The report said the first phase, covering 2026 to 2028, would focus on two climate-vulnerable districts and 30 villages, supported by an initial US$1 million contribution from Gap Inc. and Haleon. Stated aims include providing 200,000 people with access to climate-resilient WASH services, raising awareness among 300,000 people, and replenishing more than 12,000 cubic metres of water annually through rainwater harvesting, watershed conservation and groundwater recharge in the initial three-year phase.

The release cited more than 4,700 disasters in Indonesia in 2025, almost half linked to floods, and World Bank figures that Java holds 57 per cent of the population but around 6 per cent of water resources. It described the initiative as aligned with national water and climate priorities and Sustainable Development Goal 6.
