Japan and the Food and Agriculture Organization (FAO) are set to fund the rehabilitation of traditional minor irrigation tanks in Vavuniya and Trincomalee, under a new USD 1.33 million initiative announced by Sri Lanka’s Ministry of Agriculture, Livestock, Land and Irrigation.
The 12-month project, running from March 2026 to February 2027, will focus on restoring interconnected tank cascade systems that underpin agriculture across the dry and intermediate zones of the North-East.
Longstanding structural challenges, including sediment accumulation near sluice gates, the spread of invasive aquatic vegetation, and the deterioration of canals and embankments, are set to be addressed through targeted rehabilitation. Planned interventions include desilting, repairs to irrigation infrastructure, and restoring water flow between village reservoirs.
Alongside physical restoration, the project introduces climate-adaptive measures such as sensor-based water monitoring and data-driven irrigation systems. Climate-Smart Good Agricultural Practices, including Alternate Wetting and Drying methods, are expected to improve water efficiency while sustaining or enhancing crop yields.
Approximately 400 smallholder farmers are expected to benefit directly, with broader impacts anticipated on household income stability and local food security. The programme also seeks to strengthen farmer organisations responsible for water management, reinforcing community-led maintenance and distribution systems.
