Dak Nong is one of the provinces with a large pepper growing area of the Central Highlands of Viet Nam where the pepper is considered as a major crop. The sources of water for irrigation are mainly from groundwater extraction and partly from surface water in the ponds, lakes, rivers and streams. However, these water sources are exposure to potential unsustainable factors due to water scarcity, water pollution, and inefficient operation of irrigation schemes. This paper introduces research results on safe water supply for pepper producing communities in the context of climate change in Dak Nong province considering gender role in water supply in order to make recommendations to relevant agencies to ensure safe water supply in Dak Nong in particular and the Central Highlands in general, contributing to the achievement of the sustainable development goals in Vietnam.
