Abstract

The present work raises the importance of land use planning for the global climate change adaptation in coastal municipalities, in particular against the effects caused by natural hazards associated with climate change. The first part presents the current situation of the main land use planning instruments in the coastal municipalities of Mexico, in the second part the current environmental situation in said municipalities is presented, identifying the degree of their transformation, the alteration of the ecosystems in the context of watersheds, the impact on the drainage network and mangrove losses. Under these circumstances, and taking into account that the future climate scenarios indicate an increase in the intensity and frequency of tropical cyclones, most of the coastal municipalities are in a situation of very high to medium vulnerability. The third part of the text presents the concrete action that coastal municipalities can take to be more resilient in the face of the challenges posed by global climate change. These actions can be grouped into four major thematic groups: Implementation of an early warning system based on a municipal information system, conserving the first defense barrier (dunes, mangroves and coastal lagoons) against cyclones and storm tides, decrease the vulnerability of infrastructure, productive systems and population, and restoration and conservation of ecosystems with a productive approach to lessen the impact of extreme events.
