| Abstract | Peri-urbanization has been considered to be the driving force of change in land use and the loss of ecosystems and their biodiversity. In view of this premise, the research provides for the follow up, from a double perspective, historical and predictive, on changes in the area of the wetlands and progressive deforestation in Villahermosa, the most important city in the Grijalva River basin, in the State of Tabasco (Mexico). Different methods have been used: the bibliographic analysis for the period since the founding of the city until the last third of the twentieth century, the verification of aerial photographs between 1984 and 2008, and the modelling of future scenarios between 2020 and 2040. Since the Colonial period until the mid-nineteenth century, floods and unhealthy conditions limited the growth of the city despite the transformation of the surface water drainage to basin scale, which was started through the construction of levees in the seventeenth century. Subsequently, high rates of wetland loss and deforestation (-0.50 and -4.63%) increased due to the urbanization and the impact of agricultural production and petroleum programs. In the last 40 years, the fringe development has resulted in the loss of 4,008 ha of timberline vegetation and 289 ha of wetlands, with perhaps an additional 1,449 and 356 ha disappearing by 2040. These results highlight the need to redesign a metropolitan, transdisciplinary and sustainable program that respect and update the land reserves to regulate the urban sprawl. |
