Climate modelling and vulnerability assessment technology was developed to determine the threat of climate variability and climate change to Uruguay’s coastal zones and their exposure and sensitivity to it by analyzing and evaluating climatic effects on the dynamics of beaches, dunes, coastal erosion and flood risks, and the consequences for the local population, ecosystems, infrastructure and tourism. Uruguay contributes to NDC implementation by formulating, adopting, and starting the implementation of a NAP for coastal areas, and mapping the coastal vulnerability of the Rio de la Plata and the Atlantic Ocean to climate change and climate variability.
