Ferramentas de avaliação da sustentabilidade para produtores de alevinos no Estado de Mato Grosso do Sul

Abstract

The objective of this study was to present a set of tools for assessing the sustainability of rural productive activity using a sample of producers of fingerlings in the state of Mato Grosso do Sul (MS), Brazil. At first, an investigation using the EVAD method by collecting and tabulating data relating to the economic, social, environmental and institutional allowed the preparation of the sample sustainability ranking searched through the Index Development Sustainable Aquaculture (IDSA). Subsequently used the Data Envelopment Analysis (DEA) methodology for constant returns to scale, with input orientation to assess the level of environmental efficiency with regard to the use of production resources. The variables considered were exploration area in hectares, number of employees and wages paid per employee (input) and the IDSA (output). The results showed that 20% of producers employed rationally inputs, serving as a reference for the other units and that 80% of producers operate inefficiently scale, due mainly to the presence of increasing returns, reflecting the inefficiency in the allocation of resources. The next step was to develop the Rural SASP software (Software Evaluation of Rural Productive Sustainability) that aims to measure the sustainability of a sample of farmers from the definition of dimensions and variables that is the sustainability of the production system investigated. Through evaluation criteria, normalization and weighting the software generates information compiled and presented through indicators and composite indices that allows the definition of customized action plans and setting priorities to improve the sustainability of agricultural activities indicators.
