Shared basins have no shortage of agreed priorities. What they lack is a reliable path from those priorities to committed finance.
At the 11th GEF International Waters Conference ( ) in Bali, Global Water Partnership Organisation (GWPO) co-led the session "From Investable to Bankable: Financing Transboundary Water Solutions" with The World Bank Group-hosted Global Facility for Transboundary Waters.
Decades of Transboundary Diagnostic Analyses, Strategic Action Programmes and basin plans have strengthened cooperation across shared waters.
Yet few of these priorities reach the point where a government, development bank or private investor commits money, and basin institutions too often depend on short project cycles that make long-term planning harder to sustain.
GWPO's Global Head of Transboundary Water Governance, Dimitris Faloutsos, moderated a panel on how to turn priority water resources management actions agreed by riparian countries into financed interventions.
GWPO supports project preparation, technical assistance, investment structuring and de-risking, and investment mobilisation through innovative blended public-private finance to meet these needs. GWPO intends to build these elements into the design of its transboundary projects from the outset to:
🔹 Support river basin organisations and countries put fit-for-purpose, long-term financing mechanisms in place for cooperation, including pooled funds and blended structures.
🔹 Turn basin priorities into structured, financeable investment opportunities through a staged process of screening, assessment, country endorsement, feasibility work and financing strategy.
The approach draws on GWPO's investment programming, including the Continental Africa Water Investment Programme - AIP and on the Okavango's Cubango-Okavango River Basin (CORB) Fund, where GWP Southern Africa has acted as interim fund manager.
The session's recommendations for GEF-9 include funding the preparation work financiers require before they commit, setting out a financing route beyond the grant from day one, and bringing governments, banks and private investors in early.
Blended finance that brings public and private capital together is central to closing the water investment gap, and to making cooperation over shared waters last.
