Climate change is affecting the availability and distribution of raw water in the coastal region of South Flores, East Nusa Tenggara, which depends on seasonal rainfall and shallow coastal aquifers. The increase in the dry season and seawater intrusion reduces the quantity and quality of raw water. This study aims to analyze the model of community adaptation to changes in raw water distribution patterns due to climate change. The study used a mixed methods approach in four coastal villages with a survey of 120 households, rainfall data from 2013–2023, as well as groundwater surface and salinity measurements. The results showed a decrease in the availability of raw water in the dry season by 28.9% and an increase in salinity of up to 1,430 mg/L. Adaptation strategies in the form of rainwater harvesting and management of communal water distribution were able to reduce water shortage days by 24.6% (p < 0.05). This study concludes that community-based adaptation is effective in increasing the resilience of raw water distribution in the coastal areas of South Flores and needs to be integrated in the management of water resources that are adaptive to climate change.
