When the French scientist Dr. Yann Chemin during a visit to the southern Sri Lanka was trying to protect himself from “being cooked like a lobster,” with not a cloud above him, his app on the phone gave him quite a bewildering weather report.
“I was baffled as to how it could be cloudy and raining (according to the weather report) when actually it was baking-hot,” he remarked.
The idea of increasing the number of weather stations in the country, thereby enhancing the accuracy of weather reporting, was conceived as a result by Chemin, a scientist from the International Water Management Institute (IWMI), Sri Lanka. As he says, “the need is simply overwhelming.”
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.
