“…In this, region rocks of the crystalline basement (granites, gneisses, schists, etc) form about 50% of the soils. It is further aggravated by the fact that the soil of the country's depression is shallow, stony and with little drainage, affecting the quantity and groundwater quality (PINHEIRO et al, 2018).…”

“…Desalination occurs because water molecules diffuse through the membrane faster than salts and other compounds with higher molecular weight (SWITZERLAND, 2007). Thus, water produced in communities that have this system has reduced salt content and microbiological contaminants harmful to human health (PINHEIRO et al, 2018).…”

The work studies biodigestors, cisterns and desalinizers as sustainable alternatives to coexist with the semi-arid region, seeking to understand how it is possible to benefit rural populations from the production and use of social technologies. The methodology consists of bibliographical surveys from case studies and field studies on the use of these technologies in the semi-arid region. Experiences of use were selected in the municipalities of Barreira, Ocara, Redenção and Ibaretama in the state of Ceará. In the biodigestor is contextualized the most used models at Brazil and the semiarid, with emphasis on the models adopted in the municipalities of Barreira, Ocara and Redenção. In addition, to address the importance of the use of biogas and biofertilizer. In the cisterns, the types that were used in the semi-arid region were verified and the experience of the tanks program in the municipality of Ibaretama was mentioned. In the case of desalinators, the relevance of desalination systems for populations living in water scarcity was discussed, identifying the current equipment panorama installed in Barreira. As results, it was observed that it appears as a solution to meet the basic needs of populations with water supply. Biogas can be used to replace cooking gas and biofertilizer as fertilizer for plants. To do so, it requires greater attention from the public power and active involvement of the population. It is concluded that these technologies are feasible, adaptable to rural property, simple and low cost, since they tend to solve social and structural problems, besides generating income and quality of life for the populations.

Este estudo tem como objetivo avaliar os efeitos do sistema de dessalinização pertencente ao Programa Água Doce em uma comunidade rural no município de Gravatá, Semiárido pernambucano. Para isso, a metodologia adotada foi o uso de técnicas de tabulação cruzada de dados em ambiente SIG a partir das informações coletadas em plataformas públicas e relatórios técnicos, onde foi realizada a caracterização espacial da região. Além disso, foi realizada uma visita de campo, contato com os órgãos públicos e a comunidade local que foi beneficiada com essa tecnologia. Dessa forma, foi avaliado que o sistema é de extrema importância para a comunidade, pois houveram benefícios no âmbito social e econômico. A quantidade de recargas d’água através dos carros-pipa diminuiu, houve melhoria da qualidade da água através dos relatos sensoriais das famílias e a diminuição de doenças relacionadas ao uso da água. Porém, verificou-se que a região carece de tecnologias de dessalinização, além disso, detectou-se um impacto ambiental relacionado à parte residual do processo de dessalinização, o descarte do sal diretamente no solo ocasionando a sua suscetibilidade através da salinização.
