Abstract

Deforestation and poverty are challenging problems in Ethiopia. The deforestation-poverty nexus is complicated by the institutional failures related to management of natural resources. This study was conducted to analyse the determinants of deforestation in Ethiopia, Western Oromia, the case of Komto Forest in East Wollega Zone, employing primary cross-sectional data on sampled households. Multistage sampling technique was used in selecting 150 household head respondents. Volume of woody biomass consumed and sold in cubic meter (M3) was used to measure deforestation. The Heckman maximum likelihood model estimates showed that large landholding size explain lower level of deforestation. It was also found that forest product sale, and corruption behaviour of households and staff of institution aggravates deforestation. Probability of forest product use is negatively related to kerosene use and positively to road access, purpose of use, and corruption perception. The study showed that poverty and institutional failure related to the forest management are key factors determining deforestation and forest degradation in the study area. Thus solving poverty and institutional failures would help solve deforestation problem of the study area.    Key words: Deforestation, poverty, institutional failure, Heckman selection model.
埃塞俄比亚西奥罗米亚地区森林砍伐的决定因素:以Komto森林为例
森林砍伐和贫困是埃塞俄比亚面临的严峻问题。与自然资源管理有关的体制失败使毁林与贫穷的关系复杂化。本研究旨在分析埃塞俄比亚西奥罗米亚州森林砍伐的决定因素,以东沃勒加地区的Komto森林为例,采用抽样家庭的主要横截面数据。采用多阶段抽样方法,选取150名户主受访者。以立方米(M3)为单位的木质生物质消耗量和销售量被用来衡量森林砍伐。赫克曼最大似然模型估计表明,大的土地持有规模解释了低水平的森林砍伐。研究还发现,林产品销售、家庭和机构工作人员的腐败行为加剧了森林砍伐。使用林产品的可能性与煤油的使用呈负相关,与道路通道、使用目的和腐败认知呈正相关。研究表明,贫困和与森林管理有关的制度失灵是决定研究区森林砍伐和森林退化的关键因素。因此,解决贫困和制度失灵将有助于解决研究地区的森林砍伐问题。关键词:森林砍伐、贫困、制度失灵、Heckman选择模型
