在孟加拉国东部高地仍然普遍存在的轮作耕作，严重地造成了森林的损失，也是土地退化的主要原因。本文介绍了轮作耕作的原因和后果及其潜在的土地利用替代方案。提出的分析主要是定性分析，并通过逻辑回归对森林损失的原因进行补充定量分析。研究结果表明，由于贫穷和缺乏技术知识而加剧的传统土地做法是持续不可持续的轮作耕作的主要原因。人口压力、耕地不足、受教育程度低、政策规划和执行缺乏当地参与，都是影响农民继续转种决策的因素。通过农林业进行集约化土地管理是一种有希望的替代办法，可以可持续地管理剩余的森林资源。如果采用这种制度，可能会带来良好的经济回报，并可能显著减少农村贫困。
Shifting cultivation, which is still prevalent in the uplands of eastern Bangladesh, contributes significantly to forest loss and is the main cause of land degradation. This paper presents the causes and consequences of shifting cultivation and its potential land use alternatives. The analysis presented is primarily qualitative with a supplementary quantitative analysis of the causes of forest loss by logistic regression. The results of the study show that traditional land practices, exacerbated by poverty and associated with a lack of technical knowledge is the main cause for the continuation of unsustainable shifting cultivation. Population pressure, inadequate land for cultivation, low education levels, policy planning and implementation without local participation are all factors that influence farmers’ decision to continue shifting cultivation. Intensive land management through agroforestry is a promising alternative that can sustainably manage the remaining forest resources. If adopted, such systems potentially provide good economic returns, and may significantly reduce rural poverty.
