A influência climática no processo de desertificação/arenização em Gilbués-Piauí

Abstract

The concern with the environment, with a focus on methods of environmental degradation is a matter of indisputable relevance. The processes of desertification and arenization are still object of controversy among researchers due to the complexity of the dynamics of geoenvironmental and analysis parameters. The survey was developed based on the literature search, weather data and field research. The purpose and focus of the paper is to analyze the influence of climate in line with the geoenvironmental aspects in the process of desertification/arenization in Gilbués-Piauí. To achieve the results of the research were prepared graphs of annual precipitation (2011) and monthly (October) that were fundamental to elucidate the vicissitudes, concentration and uneven distribution of rainfall. Through analysis of geoenvironmental was possible to understand that the study area encompasses fragile ecosystems, especially climate variability, geological formations, and features of soils are extremely vulnerable to erosion. Thus, the region has favorable natural conditions to the occurrence and spread of desertification/arenization process.
