ABSTRACT
Central America can be defined as a region of international river basins: nearly 3941 km of borders separate Guatemala, Belize, El Salvador, Honduras, Nicaragua, Costa Rica and Panama. In a small territory of 524,000 km2, or 0.1 percent of the Earth's surface, there are 23 transboundary watersheds, representing 137,216.1 km2, close to 40 percent of the region's land surface. 1 This is an area larger than any single country in the region, which, as we discuss below, urgently requires more robust transboundary water governance regimes.
