摘要

教堂森林为植物和动物提供了安全的栖息地,为本地植物提供了种子库,提供了食物和药品来源,提供了收入来源,并减少了土壤侵蚀。他们受到牲畜放牧、木材和非木材森林产品的采伐、农田改造以及重要经济树种取代当地树木的威胁。因此,本研究旨在使用双界条件估值方法,然后是开放式问题,来估计家庭为教堂森林保护付费的意愿。该研究旨在评估家庭的支付意愿决策,引出家庭在现金和劳动力方面的支付意愿,并分析影响家庭最大支付意愿的因素。使用多阶段抽样技术,按照与样本量成比例的概率,共选择了300户家庭。结果表明,受访者以现金和劳动力支付的平均意愿分别为每年178 ETB和71.51人日。另一方面,模型结果表明,年收入、社会地位、mahiber/senbete的成员资格和教堂森林附近的土地面积对家庭的支付意愿有显著的正向影响,而抚养比则有显著的负向影响。研究结果表明,政策制定者以及国家层面的政策制定者应考虑年收入、抚养比、社会地位、mahiber/senbete成员资格和教堂森林附近的土地面积变量,以设计教堂森林的保护实践。

Determinants of households’ willingness to pay for the conservation of church forests in northwestern Ethiopia: A contingent valuation study
Abstract Church forests provide secured habitat for plants and animals, seed banks for native plants, source of food and medicines, income source and reduce soil erosion. They are threatened by livestock grazing, harvesting of timber and non-timber forest products, conversion to farmlands and the replacement of indigenous trees by economically important tree species. So, this study aimed to estimate households’ willingness to pay for the conservation of church forests using double-bounded contingent valuation method followed by open-ended questions. The study specifically aimed to assess the households’ willingness to pay decision, to elicit households’ willingness to pay in terms of cash and labor and to analyze factors affecting households’ maximum willingness to pay. A total of 300 households was selected using a multistage sampling technique followed by a probability proportional to sample size. The result indicated that the mean willingness to pay of the respondents in cash and labor is 178 ETB and 71.51 man-days per year, respectively. On the other hand, the model result indicated that annual income, social position, membership to mahiber/senbete and size of the land near to church forest had a significant and positive effect on the households’ willingness to pay, whereas dependency ratio had a significant and negative effect. The findings imply that policymakers as well as policies designed at national level should consider annual income, dependency ratio, social position, membership to mahiber/senbete and land size near to church forest variables to design conservation practices for church forests.
