Pobreza Rural e Degradação Ambiental: uma Refutação da Hipótese do Círculo Vicioso

This study analyses the relationships between rural poverty and environmental degradation in Machadinho and Maximiliano de Almeida, in the state of Rio Grande do Sul, Brazil. A database was formed based on 48 interviews with small farmers, including several environmental and socioeconomic indicators. Non-linear regression (Probit) models were estimated, with dummy variables as dependents, expressing environmental degradation, and the socioeconomic indicators as independent variables, expressing the rural poverty situations. The main results point towards a refutation of the hypothesis that rural poverty and environmental degradation are directly correlated, forming a vicious circle.

本研究针对巴西南里奥格兰德州（Rio Grande do Sul）的马查迪纽（Machadinho）与马克西米利亚诺·德阿尔梅达（Maximiliano de Almeida）两地的农村贫困与环境退化之间的关联展开剖析。研究团队依托对48名小农户的访谈构建数据库，纳入多项环境与社会经济指标。随后以表征环境退化的虚拟变量作为因变量，以表征农村贫困状况的社会经济指标作为自变量，构建并估算了非线性回归（Probit）模型。核心研究结果驳斥了"农村贫困与环境退化呈直接相关并形成恶性循环"的假说。
