/ Key causes of tropical deforestation are investigated using cross-sectional data for 90 developing countries for the period 1981-1990. Regression results reveal that deforestation is associated with both development and scarcity. Deforestation accelerates with expanding infrastructure, trade, debt, investment in the human capital base, and resource-based economic expansion. On the other hand, absolute and relative scarcities-manifested by growing population pressures, food and land shortages, fuelwood dependency, and inequalities in access to land-are also key factors explaining forest loss. Thus, results point to a fundamental environmental conundrum: Development is required if countries are to alleviate scarcity-driven forms of forest exploitation but is itself a major cause of deforestation. Can countries balance development goals with forest protection? Setting aside the issue of its practical realization, the paper concludes that forest sustainable development cannot be achieved by implementing simple technical improvements in land-use practices alone. Securing the foundations for the sustainability of the forest base will require that countries address the underlying social processes driving tropical forest loss as well.KEY WORDS: Tropical deforestation; Developing countries; Rural land-use practices; Development; Scarcity.
利用1981 - 1990年期间90个发展中国家的横截面数据,对热带森林砍伐的主要原因进行了调查。回归结果显示,森林砍伐与发展和资源稀缺都有关联。随着基础设施、贸易、债务、人力资本基础投资以及资源型经济扩张的不断扩大,森林砍伐速度加快。另一方面,由人口压力不断增大、粮食和土地短缺、对薪柴的依赖以及土地获取方面的不平等所体现的绝对和相对稀缺,也是解释森林损失的关键因素。因此,研究结果指出了一个基本的环境难题:如果各国要缓解因资源稀缺导致的森林开发形式,就需要发展,但发展本身却是森林砍伐的一个主要原因。各国能否在发展目标与森林保护之间取得平衡?暂且不谈其实际实现的问题,本文的结论是,仅通过在土地利用实践中实施简单的技术改进,无法实现森林可持续发展。要确保森林资源可持续性的基础,各国还需要解决导致热带森林损失的潜在社会进程。关键词:热带森林砍伐;发展中国家;农村土地利用实践;发展;稀缺。
