Avaliação da sustentabilidade agrícola em agroecossistemas de base familiar: uma aplicação do mesmis em assentamento rural no município de Areia-PB.

Abstract

Among the most discussed topics today, the emergence of agricultural sustainability has gained more and more ground in the face of socioeconomic and environmental problems resulting from the adoption of the principles of the Green Revolution by family agriculture, which, increasingly, threatens the survival of the humanbeing and other animal species. Hence, the aim of this study was to evaluate the comparative and cross way the sustainability of agroecosystems six family members (three referenced and three alternates) in rural community located in Areia - PB through the Framework for the Evaluation of Systems Resource Management natural Incorporating Sustainability Indicators (MESMIS). In terms of methodology, the study was conducted by applying the operational structure of MESMIS, which involved collection of secondary, primary data and applying the technique of non-participant observation. This data was analyzed using quantitative and qualitative techniques. In this sense, were pre - defined a set of 19 indicators, which assesses the conditions of the systems not desirable (1.0), regular (2.0) and desirable (3.0 ) allowed visualization aspects that need improvement to achieve sustainability by systems evaluated. Although most of these conditions have undesirable variations between not desirable and regular, two of them, one regular and one alternate that showed a varying condition from regulate to desirable. The alternative system achieved the highest benchmarks. We have seen that alternative systems have higher demand on improving the economic aspects while references have urgent need for improving the environmental aspects. However, given the necessary quest for equity in achieving sustainability, it is considered that all the systems analyzed, regardless of the condition they are in, can and should seek concurrent and regular improvement of all aspects that involve search for a better quality of life for families forming part of them.
