摘要

开展这项研究是为了确定埃塞俄比亚Humbo地区当地社区为固碳而保护的森林的经济价值。采用条件价值法(CVM),采用双有界二元概率计量方法对森林可持续经营WTP进行估算。从三个森林开发合作社中随机抽取218名受访者进行住户调查。采用双变量probit模型估算平均WTP,并确定农户保护森林WTP的决定因素。因此,预估初始投标和后续投标金额的平均WTP分别为每年104.38埃塞尔比亚比尔(ETB)和55.73埃塞尔比亚比尔。调查结果还表明,受教育程度、婚姻状况、合作社成员年数、二次投标金额、居住地与目标森林的距离以及家庭净收入与森林保护WTP显著相关。研究表明,即使是贫困家庭也愿意在非政府组织撤出后以现金捐助的方式支付平均价值来维持森林管理责任。综上所述,虽然CVM可以用于确定森林保护的WTP,但当地居民认识并给予森林的环境服务价值,并愿意维持这些利益。该研究还指出了通过以社区为基础的方法进行可持续森林管理的潜力。

Economic Valuation of Forest Conserved by Local Community for Carbon Sequestration: The Case of Humbo Community Assisted Natural Regeneration Afforestation/Reforestation (A/R) Carbon Sequestration Project; SNNPRS, Ethiopia
The study was carried out to determine the economic value of forest conserved by local community for carbon sequestration in the Humbo District, Ethiopia. The contingent valuation method (CVM) using the double bounded bivariate probit econometric method was employed to estimate WTP for sustainable forest management. Household survey was randomly conducted in 218 respondents purposively selected from three forest development cooperatives. The bivariate probit model was run to estimate mean WTP and to identify the determinant factors for farmers’ WTP for forest conservation. Thus, the mean WTP with covariates was estimated to be 104.38 Ethiopian Birr (ETB) and 55.73 ETB1 per year for the initial bid and for the follow-up bid amount, respectively. The result also indicated that respondents’ level of education, marital status, years of membership in the cooperatives, second bid amount, distance of residence from forest of interest, and net family income were significantly related to WTP for forest conservation. The study showed that even the poor households were willing to pay the average values in terms of cash contribution to maintain the forest management responsibility following the withdrawal of the NGO. In conclusion, whereas CVM can be applied to determine WTP for forest conservation, local people recognize and give value to the environmental services of the forest and are willing to maintain those benefits. The study also indicates the potential for sustainable forest management through community-based approach.
