Aprovechamiento sustentable de áridos dunarios en el Sudeste de la Provincia de Buenos Aires
Resumen
The coastal dunes are part of the coast that is made up of the beach and the dune itself. lt is an ecological system in constant natural change and evolving on a human time scale. In the municipalities of Lobería and Necochea there are human settlements, extraction of aggregates, tourism and other anthropic activities that modify the natural mobility of the dunes, affecting the urban areas of Arenas Verdes and Costa Bonita towns, generating the loss of a significant number of public and private lots, with the consequent economic damages. This document offers mechanisms that will provide the necessary aggregates to support the construction industry in southeast Buenos Aires and, at the same time, reduce the geomorphological risk caused by migrant dunes in vulnerable urban areas and minimize the prejudices related to the extractive mining activity. The proposal is backed by an environmental sustainability exploitation scheme, with a resource renewal rate generated by transportation and mobility of the dune field over an urbanized area, allowing a reasonable extraction of aggregates from the front of the transversal dunes, with minimal damage to both, coastal ecosystems and the beach environment.
