Barragem subterrânea como tecnologia de convivência com o semiárido - o caso do Território da Cidadania do Alto Oeste Potiguar.

Abstract

The climate of the brazilian semi-arid northeast has generally water shortages. In most municipalities in the region, the precipitation is in a range that goes from 200 mm to 800 mm annually. With high evaporation rates and relatively high temperatures, the most populated semi-arid region of the world, this semiaridez condition. This scenario has contributed to the formulation of public policies for family farming. In the Territory of the Higt West Potiguar, family farming is an important economic sector. In recent years has seen an expansion of public policies for the coexistence of the family farmer with the semi-arid region. Underground dams, while coexistence technology has become - is important for the development of small farmers. In this context, the study aimed to evaluate the effects of the deployment of underground dams on small farms in the Territory of the High Citizenship Potiguar West as a way to promote coexistence with semiaridez condition. The study area consists of the Higt West Potiguar which is a brazilian region of Rio Grande do Norte State (RN), and the study was designed by the methods: qualitative and quantitative. With regard to the purposes of research can be considered as evaluation of results, case study and explanatory. In relation to the media, the study is characterized as a survey and documentary research. The study universe was assisted by family farmers of underground dams programs in the Territory of the High Citizenship Potiguar West, with a total of thirty-five and sampling took place accessibility being obtained sample of twenty farmers benefit from the programs of underground dams. Was done using content analysis to the qualitative method and the quantitative method was used descriptive statistics, where data were presented through some measures of dispersion and central tendencies, followed by graphics. From the data analysis, it was shown that 100% of farmers belong to any social movement, these farmers have a positive perception of the dams programs. From the results of the chemical analysis of soil, soil classification of internal areas of the dams was studied according CEes, PST, and pH, classifying them, and 45% as no salt problems, 5% as sodium salt and sodic soil as 55%.
