Vegetation conservation to reduce hidrometeorological risks on a border metropoli

Land cover change affects landscape dynamics, especially in big cities, which leads to increased risks when extreme meteorological events occurs and reduces resilience capacity. The Tijuana-Tecate-Rosarito metropolitan area, characterized by a rough topography, lack of green space, high biodiversity...

description Land cover change affects landscape dynamics, especially in big cities, which leads to increased risks when extreme meteorological events occurs and reduces resilience capacity. The Tijuana-Tecate-Rosarito metropolitan area, characterized by a rough topography, lack of green space, high biodiversity and endemism, is prone to landslide and floods risks. To solve these problems, this study proposes a green infrastructure plan (interconnected green spaces). Based on the construction of a land use-cover map using satellite images, the plan includes the conservation of risk areas of steep slopes, water courses and unique biodiversity areas and analyzes different scenarios and their legal feasibility. Results show that by enforcing legislation and not constructing on risk areas, a great part of the natural vegetation with good connectedness can be conserved. If special ecological areas are introduced, conservation areas and their connectedness increase. That said, existing regulations are insufficient, dispersed or not enforced.

El cambio de uso del suelo afecta la dinámica del paisaje especialmente en las ciudades, lo que incrementa el riesgo ante eventos meteorológicos extremos y reduce la capacidad de resiliencia. La Zona Metropolitana de Tijuana-Tecate-Rosarito, con topografía accidentada, pocas áreas verdes, alta biodiversidad y endemismos, presenta riesgos de deslaves e inundaciones. Se propone crear infraestructura verde (red de áreas verdes) sobre pendientes pronunciadas, cursos de agua y áreas con biodiversidad especial. Con estas variables e imágenes de satélite se construyeron mapas de usos del suelo y vegetación y escenarios de conservación, se analizó su conectividad y su factibilidad legal. Gran parte de la vegetación con alta conectividad se conserva solo cumpliendo la legislación de no construir en áreas de riesgo. Al sumar las áreas con biodiversidad especial, aumenta la superficie a conservar y su conectividad. Sin embargo, la legislación existente no es suficiente, está dispersa o no se aplica.
