Transboundary Water Management

Regional cooperation on transboundary waters is a public good that benefits all parties and can open new opportunities for riparian states to sustainably develop water resources.



SIWI advances equitable and cooperative development in Transboundary Water Management (TWM), both in individual basins and globally, by:

  • Developing, disseminating and promoting research and tools
  • Facilitating platforms for sharing experiences, knowledge and perspectives on equitable, cooperative transboundary water development
  • Promoting the formation of management frameworks for transboundary waters
  • Building capacity in partner organisations for them to better deliver on their mandates in TWM

Our services

SIWI’s experts provide support to transboundary water management in four main areas:

Applied research and tools
SIWI critically analyses new trends and approaches to TWM in regions. Based on its research and through practical experience in basins, SIWI develops tools and methods to unpack the development opportunities in a transboundary water setting. Our work is always are grounded in detailed context-specific political economy analysis. By outlining the incentives and benefits of deepening cooperation between parties sharing transboundary waters, we promote the formation of regional management frameworks for them.

Third party facilitation and support
SIWI provide platforms for states to meet and discuss ways forward in a neutral setting and can serve as a trusted third party facilitator to support regional development agendas. We help parties engage in transboundary processes with a long-term perspective of promoting both security and development, and encourage a holistic approach to TWM that includes other sectors which both affect and are affected by it.

Regional hydro-economic modeling
Hydroeconomic modelling is used to represent hydrologic, engineering, environmental and economic aspects of water resources at local, regional and transboundary scales. SIWI performs modelling that enables decision makers to gain common understanding of the potential benefits, risks, and opportunities for each party that are presented by alternate strategies and policies to develop water resources.

Capacity building
SIWI develops tailored capacity-building programmes, built around innovative knowledge and tools, to better equip managers and institutions of transboundary waters to work effectively, thereby also supporting improved cooperation in these basins.
