Water plays a critical role in the agricultural sector, particularly rice cultivation, making reliable water a necessity for Cambodian farmers. The need for water is very much obvious for those whose rice paddy fields are too remote to access water from its source, especially during the dry spell. While most of Cambodian rural farmers rely heavily on rain-fed rice cultivation, climate change has influenced considerable changes in rain distribution. Building and rehabilitating resilient irrigation schemes to adapt to the changing climate is of critical importance, as it will revitalize agricultural productivity, thereby improving livelihoods.
