Risk desertification in Cabrobó / PE : climatic conditions and human activities | Risco climático para a ocorrência da ferrugem do cafeeiro

Abstract

The region of Desertification Core Cabrobó / PE has low annual rainfall and spatial distribution of heterogeneous precipitation. In the southern city of Cabrobó, where is the island of the Assumption, the combination of local climate characteristics, associated with atmospheric dynamics, and especially with the presence of human activities, allows the occurrence of a sharp process of land degradation. The objective of this study is to evaluate the risk of desertification in Cabrobó / PE, considering the climatic conditions and anthropogenic activities in the region. The climatic conditions were analyzed by the spatial distribution of precipitation, air temperature and aridity index, interpolating data from 58 stations located in the study area and its surroundings. In order to evaluate the anthropogenic activities in the region, a field visit was carried out in places that are in the process of degradation. The results indicated that the climatic conditions favor the process of desertification, but developed human activities such as irrigated agriculture by flooding, extensive cattle ranching and deforestation, contribute greatly to the advanced state of disrepair that some parts of the region meet.
