The goal of the Global Water Partnership South Asia (GWP SAS) is to work towards meeting water challenges through partnerships and promote Integrated Water Resource Management (IWRM) in South Asia.

The Global Water Partnership South Asia (GWP SAS) is a constituent of the GWP network. GWP SAS represents in Bangladesh, Bhutan, India, Nepal, Pakistan and Sri Lanka linked to the global network through the respective Country Water Partnerships (CWPs), which brought together with the common objective of promoting Integrated Water Resources Management (IWRM) in the region. In addition, it now remains for GWP SAS to meet the challenge of implementing the Sustainable Development Goals in South Asia region and guarantee that effective solutions to water security challenges will be implemented.

The Global Water Partnership (GWP) was founded in 1996 by the World Bank, the United Nations Development Programme (UNDP) and the Swedish International Development Cooperation Agency (SIDA) to foster IWRM.

IWRM is a process which promotes the coordinated development and management of water, land and related resources in order to maximise economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems.
