This document outlines the activities and execution arrangements for a project to improve governance of the transboundary Stampriet-Kalahari/Karoo Aquifer. The project has two main components: 1) building recognition of the shared nature of the resource through a science-based assessment, and 2) reaching consensus on transboundary governance mechanisms. Key activities include an indicator-based assessment of the aquifer, development of an information management system, establishment of a multi-country consultative body, and training to enhance awareness of international law on transboundary aquifers. Execution will be led by a steering committee and project team from the three countries sharing the aquifer.
