Trans-Boundary Water Assessment Programme (TWAP)

TWAP works with the water systems of the world – aquifers, lakes, rivers, large marine ecosystems and open oceans - to support the socioeconomic development and wellbeing of the world’s population. It does so by improving the knowledge of ground water aquifers to provide a broad characterization of these aquifer systems. Many of these water systems are shared by two or more nations, resulting in a complex web of environmental, political, economic and security interdependencies.

Under these circumstances, TWAP became the first global-scale assessment that improves knowledge for informed decision-making, raising awareness and fostering cooperation among all stakeholders. From 2014-2015, a series of workshops and trainings for countries from the Southern Africa Development Community (SADC) and the Intercontinental Government Authority on Development (IGAD) took place in Nairobi, Kenya; as well as regional workshop for the sub-regions of the Economic Community of West African States (ECOWAS) and Economic Community of Central African States (ECCAS) in Dakar, Senegal. These TWAP initiative has contributed to creating dialogues among involved Member States and experts, to provide a certain characterization of the trans-boundary aquifers. UNESCO is working with experts among its Member States to better characterize the different aquifers and to propose a mechanism for its peaceful and sustainable management.
