This document outlines several proposals for a Transboundary Water Cooperation Programme, including: 1) Providing guidance on implementing various regional water treaties through technical papers and case studies from different river basins. 2) Developing tailored trainings on topics like the UN Water Convention through both online and regional workshops. 3) Expanding activities to support transboundary water cooperation like those under the SITWA project to other regions through partnerships. 4) Sharing best practices on transboundary water management between regions.
