Establishment of a non‐governmental regional approach to La Plata River Basin integrated watershed management promoted throughout three international workshops supported by UN and Japanese agencies, led by ILEC

Abstract

AbstractThe La Plata River Basin is one of the largest international river basins in the world, with an area of about 3 million km2. It spreads across five countries (Argentina, Bolivia, Brazil, Paraguay and Uruguay), and its water resources are essential for their economic development. Together with reservoir development, extensive deforestation, intensive agriculture practices and large urban developments took place in the Paraná, Paraguay and Uruguay basins, affecting environmental conditions and raising important issues concerning water resources use and conservation. Therefore, the need to promote participatory and cooperative efforts among water resources stakeholders, as well as the systematic exchange of information and experiences on common regional problems among organizations and experts from throughout the basin who are devoted to water resources use and management, was reported by researchers and managers gathered at the First and Second International Workshops on Regional Approaches for Reservoir Development and Management in the La Plata River Basin (held in 1991 and 1994). As a concrete response to this need, the efforts of a number of organizations from various countries within the basin, with the support of international and national governmental organizations, resulted in the foundation of La Plata River Basin Environmental Research and Management Network (RIGA) in March 2001. This was within the framework of the Third International Workshop, which was precisely one of the short‐term activities included in the RIGA Action Plan. During the preparatory processes for the RIGA Network, the presence of Japanese cooperation supporting the La Plata River Basin Workshops through a non‐governmental international organization (ILEC) played an important role in stimulating such an organization‐based joint approach in the basin. This outcome, although not originally planned, constituted a welcomed byproduct of its main specific interest in the region, which was the establishment of international sustainable management guidelines for lake and reservoir management.
