About this project


The project aims to enhance bi-national efforts of Peru and Ecuador for Integrated Transboundary Water Resources Management (ITWRM) in the three main aquifers and watersheds shared by the two countries in the Pacific Ocean drainage basin - Puyango-Tumbes, Catamayo-Chira and Zarumilla. It will give special attention to integrating groundwater concerns and opportunities and extreme manifestations of climate variability and change in the area, including the cyclicality of El Nino-Southern Oscillation (ENSO).The aquifers and linked river basins Zarumilla, Puyango-Tumbes and Catamayo-Chira contain an important, but often highly variable, water supply that is essential to the region socio-economic development and to the integrity of its ecosystems. These resources are threatened by overexploitation, pollution and inefficient management, as well as by climate variability and change.


Strengthening institutional, policy, legal and scientific-technical capacities to implement Integrated Transboundary Water Resources Management in Puyango-Tumbes, Catamayo- Chira and Zarumilla River Basins and Aquifers, integrating climate variability concerns.
