Sri Lanka faces another episode of flooding and landslides, as the southwest monsoons continue to trigger extreme weather in parts of the country. IWMI together with the Disaster Management Centre of Sri Lanka (DMC-SL) have activated their disaster charter with Sentinel Asia (as of May 26). Within this framework, the Institute has been providing satellite-based high-resolution maps of the affected regions to the DMC and military to assist with rescue missions and further assessments. IWMI’s participation forms part of the CGIAR Research Program on Water, Land and Ecosystems (WLE), supported by the CGIAR Fund.
The DMC has appointed IWMI as the key institute to facilitate coordination with space agencies for satellite data acquisition and to share the value-added products with stakeholders in Sri Lanka. The first satellite image obtained on May 28, via the German Aerospace Centre (DLR), showed vast areas of standing floodwaters along the Southern and Western Provinces. Initial estimates from satellite images indicate that Matara (with 49.3 square kilometers of flooded area) and Kalutara (with 31.6 square kilometers) are the worst affected districts, followed by Galle (20.2), Rathnapura (14.9), Colombo (5.6) and Gampaha (4.5). Detailed statistics on the affected regions have been shared with local authorities.
So far, thousands of people have been reported missing and hundreds killed. Over 100,000 have been recorded as displaced and 500,000 directly affected across many districts, according to initial estimates from the DMC. More rainfall is expected in the coming days.

Population pressure and increasing water competition in a changing climate require us to take stock of the availability and use of water across scales. Water availability not only influences farmers’ commercial prospects but also irrigation-related enterprises and agri-businesses. Greater water scarcity could jeopardize irrigation and agricultural markets while excessive water use can lead to declining ecosystems, water quality and soil health. IWMI advises development partners and the public and private sectors on all aspects of water resource availability and use through a variety of advanced modeling and remote-sensing products and tools, including 
The ability of farmers to engage in or expand irrigation depends on the prevailing socioeconomic, ecological and political contexts, which are often complex, non-linear and changeable. Overcoming systemic barriers to farmer-led irrigation development while taking advantage of existing opportunities 
A lack of affordable credit, particularly for women and resource-poor farmers, is one of the main barriers to expanding farmer-led irrigation in low- and middle-income countries. But 
Scaling farmer-led irrigation requires strengthening human capacity and knowledge exchange among all actors and stakeholders involved. IWMI takes an action research approach, working with national and international research institutions, governments, extension agents and public and private organizations to co-develop the scaling ecosystem and strengthen capacity to drive scaling networks and collective action.
