The Salween is Asia’s last free-flowing international river, home to 7,000 species of plants, 80 rare or endangered animals and fish in China, as well as about 7 million people who depend on its ecosystem for their livelihoods. Currently, a total of 15 hydropower dams are planned on the mainstream of the Salween, eight within Myanmar.
Human rights advocates have expressed concerns about the Salween development projects, which would affect populations in three countries. Known as Nu in China, Salawin in Thailand and Thanlwin in Myanmar, the river originates on the Tibetan plateau, flows through China’s Yunnan Province, and passes through Myanmar, in places forming the border with Thailand, before emptying into the Andaman Sea.
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.
