Southeast Asia

Countries in Southeast Asia have abundant water resources. However, due to the uneven distribution of these resources, much of the region is water insecure. Geographic location and seasonal variations, as well as varying degrees of economic development and different political systems, greatly affect people’s access to water and land resources. The Greater Mekong subregion comprises Cambodia, Lao PDR, Myanmar, Thailand, Vietnam and the People’s Republic of China (specifically Yunnan Province and Guangxi Zhuang Autonomous Region).

Countries in the Greater Mekong are changing as a result of increasing economic growth, population and urbanization as well as rapid rural transformations. The Greater Mekong has a combined population of around 345,185. By 2050, it is expected that the subregion will be at least 50% urbanized. Governments in the region recognize the critical role that water and land resources management can play in future development.

IWMI in Southeast Asia

IWMI plays a crucial role in addressing water-related challenges in Southeast Asia. With a focus on water, food, ecosystems, climate change, growth, and inclusion, IWMI recognizes the complex dynamics of water resources in the region. Despite abundant water resources, uneven distribution and diverse socioeconomic factors impact access to water and land.

IWMI’s expertise lies in promoting effective irrigation management, facilitating community-based schemes, and enhancing agricultural resilience. Additionally, IWMI is actively involved in groundwater development, sustainable fisheries integration into irrigation systems, climate change adaptation, and optimizing hydropower benefits for water users. IWMI’s research efforts contribute significantly to improving water and land resource management in Southeast Asia, fostering resilience, and supporting sustainable development initiatives.
