Abstract
English abstract: The Grupo Gestor Binacional de la Cuenca del Río Goascorán (GGBCG) was created in 2007 as an original initiative managing a shared basin in the Eastern part of El Salvador-Honduras boundary. In less than twenty years, the issue of confrontation in this border area has led to a logical approach to reconciliation and cooperation through shared management of the Río Goascorán basin. This article analyzes the ways in which the actors involved understand this cooperation. The initiative that is studied is part of a regional context that is of interest for the management of transboundary river basins. Several elements relevant to the analyzed case are addressed, including the difficulty of cross-border action and shared management, the turnover of the actors involved, and the forms of institutionalization on which the management of transboundary watersheds can be based.
