General bases for the development of hydroclimatic risk reduction studies in cities: lessons learned from the Emerging and Sustainable Cities initiative in the face of the challenge of climate change in Latin America and the Caribbean

Urban agglomerations constitute centers of concentration of risks and opportunities for more than 80% of the population of Latin America and the Caribbean (LAC), and represent ideal work units to carry out studies of risks of natural origin. This document presents guidelines for carrying out quantitative and probabilistic analyzes of risks associated with hydroclimatic phenomena and linked to climate change in cities. Coastal, river and extreme rain flooding, hurricanes, winds, beach erosion and urban drought. Much of the methodology presented has been applied in the Emerging and Sustainable Cities Initiative (ICES) of the Inter-American Development Bank, a pioneering program that has been developed from 2011 to 2018. The document presents numerous practical examples taken from the work of said initiative.
