Climatic elements such as precipitation and temperature are essential in agriculture, especially in semi-arid, where is specifically the city of Poço Verde/Se, besides other factors such as economic, social, political and technological. Edaphic constraints represented by pedological composition, comprising the Inceptisols, and Entisols Planosols are conducive to farming, though, need to be corrected, using fertilizer. There, in the city, due to inappropriate areas of outcropping rocks as a result of erosion, resulting from human activities and natural processes. The climate is conceived as dynamic qualitative analysis based on reading Monteiro, and Mendonça Pinto and Oliveira. The dynamic environment is scored on the association between nature and society. In this sense, this paper aims to analyze the relationship between climate conditions and anthropogenic lead in the semiarid area of Poço Verde/ SE, proposing understand the behavior climatic variations of precipitation and extreme events likely, specifically drought, not only a natural phenomenon, but its aspects, political and economic, that affect quality of life. This research method is based on the GTP-geosystem, Planning and Landscape, qualitative and quantitative in nature, the idea of having a holistic view of the paid up space. The methodological procedures outlined that this work were: bibliographic and documentary; fieldwork through secondary and primary data through semi-structured interviews and questionnaires with social actors in thematic mapping system Georeferenced Information Processing in ArcGIS version 9.3. Construction of the water balance method of Thornthwaite & Mather (1955). Quantification and data tabulation, analysis, interpretation and description. It is thus understandable that the precipitation variability is striking and irregular, spatially; presents water deficit. ENOS events play a significant role in the dynamics of rain, the genetic character of climatic anomalies producer, overlapping to human actions, wide effect on the local scale. The occupation of agricultural land dominates the local economy, with the agrarian structure of small farms with maize and beans as main crops, directly linked to rainfall distribution and adapted to the small thermal variation of the Poço Verde tropicality itself. The vegetation consists of the savanna biome and amended its origin. The urban population has more than rural, composed of 21,968 inhabitants. The welfare state develops actions, building wells freshwater and brackish water, dams and water distribution pipes for cars. Drought is one of climatic hazards in the city, classified as seasonal and contingent, which interferes with the local farming and has impact on urban life. There are reports of hail. Thus sertanejos poçoverdenses suffer in the dry season and drought, reflected both in the field and in the city, and there are real correlation between the physical, productive, economic, labor relations and social and public policies.
