This document summarizes the key findings of a project studying climate change impacts in coastal areas of the Rio de la Plata River. The project used a participatory approach, training local stakeholders to identify vulnerable areas and understand risk perception. Modeling found housing damage costs could increase by 20-33% due to climate change. The study also identified institutional barriers to adaptation, including a lack of integration between climate and development planning, limited technical capacity, and tensions between scientific and local information needs. However, opportunities exist to address these barriers through community involvement, improved urban planning, and raising awareness among decision-makers.
