The study analyzes the 'El Morro' catchment in Argentina, where the conversion of native forests to agriculture has led to rising water tables and the emergence of new streams. The authors identify five mechanisms of competition: plants taking water from streams via unsaturated uptake (mechanism 1), focalized saturated uptake in wetlands (mechanism 2), and distributed saturated uptake in forests (mechanism 3); and streams taking water from plants through streambed deepening (mechanism 4) and sediment deposition (mechanism 5). Findings indicate that while unsaturated uptake previously suppressed streamflow, current high water tables have made saturated uptake by forests and wetlands significant, though deepening streams are now actively reclaiming water by lowering local water tables.

The project achieved a 'Satisfactory-Highly Satisfactory' rating for its objectives, successfully strengthening national policies and engaging nine local communities in mangrove restoration and conservation. Key achievements include the update of national regulations in Panama and Ecuador, the development of a National Mangrove Plan in Ecuador (February 2019), and the creation of fisheries management plans in El Morro, Ecuador. While regional coordination through the CPPS was effective, the final regional strategy awaited official endorsement. Sustainability is rated as 'moderately likely' due to risks regarding long-term funding for on-the-ground activities.
