Impacto histórico de la deforestación y la modificación de los ríos en la morfología de la costa del sur del Golfo de México

Abstract

The Mezcalapa-Grijalva-Usumacinta watershed systems have experienced continuous human-made alterations since the 17th century. The alteration of the hydro-sediment balance has affected the morphodynamics of the delta with conspicuous impacts on the evolution of the shoreline. Historical maps and narratives are helpful to assess these changes at different spatial and temporal scales. The results emphasize the role of historical archives, maps, and aerial photographs as valuable tools for understanding altered ecological processes in large watersheds.
