La hidroclimatología e impactos ambientales: degradacion ambiental y desertificación

Abstract

At the moment it is assumed that the process of the desertification is the result of the combination of a considerable number of climatic, geographical, topographical, hydrological factors, edaphics, biotics that interact with the human activities negatively on the environment to different scales. This process constitutes an environmental problem of first magnitude that is accentuated and it is increased in the semi-arid areas. The floor is a very important element of the ecosystems that completes a series of environmental and socio-economic basic functions that is in turn influenced by the environmental factors. Indeed, in the same way that certain climatic changes influenced by the human activity cause the process of the desertification, the changes in the properties of the soil caused by the human interve bear mechanisms of the loss of their basic ecological functions, being a clear symptom of their degradation, of the loss of the environmental quality and of the desertification in extensive areas of the Planet. Presently work is sustained the idea that the studies dedicated to the evaluation of the degradation and the quality of the soil starting from its indicators, it is a valid methodology to characterize susceptible degraded areas to the process of the desertification, as well as to promote actions that you can help to combat it.
