Estudo da sustentabilidade agrícola em município amazônico com análise envoltória de dados

Abstract: ResumoO conceito de sustentabilidade agrícola considera diferentes dimensões. Entretanto, tem como base a valorização dos recursos internos dos sistemas agrícolas produtivos, que se traduz pela manutenção desses sistemas de produção e, consequentemente, de sua produtividade, ao longo do tempo. Este artigo tem como objetivo medir a sustentabilidade de produtores agrícolas a partir de modelos Análise de Envoltória de Dados (Data Envelopment Analysis -DEA) com restrições aos pesos. Nesta abordagem, além de consid… Show more

“…Initially, the data envelopment analysis is applied for all groups together, under the assumption of constant returns and product orientation, to allow comparisons of efficiency scores betweem groups and to obtain the longterm efficiency. This procedure is necessary because when comparing decision making units (DMU) of different groups in the same model, joint estimated efficiency, the average efficiency has an absolute sense; however, comparing technical measures of efficiency between groups, estimated separately, it has the interpretation of homogeneity, that is, groups with higher scores are more homogeneous (Gomes et al, 2009).…”

“…It is desired that the output number of passengers transported has a greater weight than the output total fee. However, as the two variables are measured in different units, the previous statement, by itself, is meaningless (Allen et al, 1997;Gomes et al, 2009a). For it to make sense, it would be necessary to normalise the data, which would bring problems of interpreting the results of the redistribution of the total fee output.…”

“…Para tanto, elencam um conjunto de determinantes da sustentabilidade agrícola, tais como população, produção, consumo, emprego, tecnologia, produtividade, acesso e escoamento produtivo, rentabilidade, instituições e tempo. Já Rezende (1986,1988), Carvalho (1989), Dias (1989), Guasquez e Villa Verde (1990), Goldin e Rezende (1990), Ferreira Filho (1994 Gomes et al (2009) também afirmam que há diversas abordagens para avaliar a sustentabilidade agrícola, dentre as quais as que propõem a construção de índices agregados multidimensionais que avaliem o desempenho do sistema produtivo. Nesta abordagem, podem ser citados alguns trabalhos como Pannell e Glenn (2000), Rigby et al (2001), López-Ridaura et al (2002), Lopes e Almeida (2003), Pacini et al (2003), Fernandes (2004), Gomes (2004) e Parra-Lopez et al (2008.…”
