Riesgo, vulnerabilidad y cambio climático en suelo de conservación ecológica de la Ciudad de México. El caso de los humedales de Tláhuac

Abstract

global climate change has been recognized as an important treat for species survival and natural and social systems health. In genera research had focused in analyzing the resulting ecological and hydrological GCC impacts. Particularly, wetlands are vulnerable to quantitative and qualitative water supplies changes, and because of local, regional and global hydrological regimes variations is expect that CC will have considerable effects on these ecosystems. This article analyzes, the relevance of the Protected Natural Areas PNA in Mexico City as climate change buffering. Since PNA particularly the wetlands confer resilience to the urban system, their protection might be decreasing the risk and vulnerability of the City. Wetlands have an important function as a regulator water storage that prevents overfloods due to torrential storms, also act as a germplasm and biodiversity reservoir. Here, we described two principal aspects that explain how a city may became resilient. In the first one, we proposed from the adaptative complex system theory, that a Metropole as Mexico City, should be understood as a socio-ecological system with the potentiality to resist and to be resilient to the expected effects of CC. However, its resilience will depend on the present sociopolitical decisions making, as well as the socio-economical developmental model we want to follow. With the aim to explain how the PNAs and specially Tláhuac wetlands helps to increase the urban resilience against the expected CC impacts, we present the ecological and social diagnostic analysis of this socio-ecosystem. Resilience still a poor studied element, not yet included as an approach in public politics. Actually, regard resilience as fundamental approach is considering the indivisibility o the human-nature binomial.
