The Green Revolution spread ‘modern agriculture’ to agricultural areas of the world through the creation of new products and practices. The adoption of agricultural technology brought about great changes in land use. The growth of new cultivated varieties, expansion of existing crops and deforestation are some of the results of this process. This article evaluates the relationship between agricultural technologies (use of agricultural machinery and technical assistance) and land use in Brazil. For that, a spatial econometric model of Simultaneous Equations Systems was used. Our approach highlights the importance of the regional technological pattern (represented by spatially lagged technological variables) on land use. The results corroborate the Borlaug hypothesis that the use of agricultural technologies can enable the maintenance of agricultural areas while preserving forest areas. In addition, with the incorporation of spatially lagged technological variables, we could observe the presence of technological spillovers in agriculture.

绿色革命通过创造新产品和新做法，将“现代农业”传播到世界各地的农业地区。农业技术的采用带来了土地使用的巨大变化。新栽培品种的增长，现有作物的扩大和森林砍伐是这一过程的一些结果。本文评估了巴西的农业技术（使用农业机械和技术援助）与土地使用之间的关系。为此，使用了联立方程系统的空间计量经济学模型。我们的方法强调了区域技术模式（以空间滞后的技术变量表示）对土地利用的重要性。该结果证实了Borlaug的假说，即使用农业技术可以在维持森林面积的同时维持农业面积。此外，通过结合空间滞后的技术变量，我们可以观察到农业中存在技术溢出效应。
