Available in PDF, EPUB and Kindle. Book excerpt: O principal objetivo desta tese e construir um indice de sustentabilidade que retrate uma situacao de desenvolvimento agricola. Para isso, parte-se da demarcacao dos limites conceituais do tema e da forma de melhor proceder a esta medicao. O indice em questao pode ser validado a partir da verificacao de sua aplicabilidade. Neste sentido, procede-se a um estudo de caso baseado em dados de produtores colonos dos projetos da CODEVASF do Vale do Submedio Sao Francisco, uma regiao tambem conhecida como Polo Economico Petrolina-Juazeiro e que tem sido apontada como uma das alternativas de desenvolvimento do Nordeste brasileiro. Agricultura sustentavel, vista dentro do escopo do desenvolvimento sustentavel, e interpretada como uma conjuncao de fatores economicos, sociais e ambientais. Cada um desses fatores encontra, em argumentos de autores diversos, uma anfase que o justifica mais ou menos importante nesta conceituacao. A medicao da sustentabilidade se da basicamente em tres niveis: na definicao de indicadores de sustentabilidade para uma regiao de estudo, na criacao de um unico indice de sustentabilidade com alguns dos indicadores sugeridos e, finalmente, na estimacao de uma relacao causal entre o indice criado e os indicadores de sustentabilidade nao utilizados na criacao do indice. Os indicadores sugeridos sao do tipo fisico e se guiam pela estrutura de tres niveis de indicadores da ONU, que sao os indicadores de fatores condicionantes da sustentabilidade, indicadores de estado da sustentabilidade e indicadores criadas. Cada um destes indicadores foi especificamente construido neste trabalho para caracterizar a regiao de interesse, que apresenta caracteristicas agroecologicas e produtivas especificas. O metodo dos componentes principais e defendido neste trabalho como forma de agregacao dos indicadores de estado da sustentabilidade para que se chegue a um indice de sustentabilidade. Para a relacao causal entre os indicadores de fatores condicionantes e de resposta e o indice de sustentabilidade estimado, utiliza-se um modelo de regressao linear. Os argumentos construidos nesta tese dao utilizados para a analise dos principais elementos de sustentabilidade da regiao e dos perimetros onde se localizam os seus estabelecimentos. Sao tambem analisados os principais determinantes da sustentabilidade em termos de fatores condicionantes e de respostas.
