本文探讨了发展中国家农村地区人口变化过程与环境之间可能存在的关系。审查了以森林砍伐（高地森林和低地森林）形式加剧退化的证据。土壤侵蚀和土壤干燥。该概念框架考虑了人口增长以及土地压力增加引起的人口统计和经济行为的变化，但这里的重点是土地扩张（通常涉及内部移民）和土地集约化形式的经济变化。尽管数据有问题。观察到了预期的关系：农村人口增长较高的国家往往可耕地面积和相关森林砍伐的增幅较大，但集约化效应似乎更强。该论文的结论是对政策和进一步研究的影响。
This paper examines possible relationships between demographic processes and the environment in rural areas in developing countries. Evidence is reviewed on increasing degradation in the forms of deforestation (of highland forests as well as lowland forests). soil erosion and soil desiccation. The conceptual framework considers changes in demographics as well as economic behaviour being induced by population growth and increasing pressures upon the land, but the focus here is on economic changes in the form of land extensification-often involving internal migration-and land intensification. Despite data problems. thc expected relationships are observed: countries with higher rural population growth tend to have larger increases in the arable land area and associated deforestation, but the intensification effects appear stronger. Thc paper concludes with implications for policy and further research.
