| Shrnutí: | 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. |
