Storms, floods, droughts, and other extreme weather events can threaten urban and rural areas, from small regions to entire nations. Along with growing populations and economies, losses from natural hazards are rising in the World's most exposed areas as our climate continues to change. The Economics of Climate Adaptation (ECA) is a decision-making support framework that integrates climate vulnerability and risk assessments with economic and sustainability impact studies to determine the portfolio of optimal adaptation measures for various climate risks. This report presents an executive summary of the different stages of the process of implementation of the ECA study and the final recommendations for adaptation measures to flood events in the Municipality of San Pedro Sula. A significant source of information for the study was the Plan Maestro de Desarrollo Municipal (PMDM), which the Municipality carried out through extensive research and data collection.
