摘要

土地退化,特别是土壤侵蚀是埃塞俄比亚最严重的环境问题之一。实现摆脱土地退化问题和贫困的可持续途径需要人们积极参与土壤保护实践,并了解农民如何重视土壤保护。本研究的目的是调查埃塞俄比亚奥罗米亚地区州北绍阿库尤沃雷达的农民为改善公共土地上的土壤保持措施付费的意愿。采用条件估值法的双界二分类格式来引出被调查者的WTP。从184个家庭收集的数据用于分析。Probit和Bivariate Probit模型都进行了估计。研究结果表明,大多数受访者已经意识到土壤侵蚀问题,并愿意为保护措施付费。性别、受教育程度、牲畜、收入、土地坡度、认知和延伸访问频率等因素对WTP用于土壤保持的概率有显著的正向影响。研究还表明,从双界二分类选择格式估计的平均WTP为每年85.36个工作日。从双边界CVM计算,本研究土壤保持的总价值为每年10,909,349人日(196,368,282 ETB)。研究表明,农民已经意识到水土流失问题,并愿意为改善水土保持措施付出劳动贡献。因此,建议的政策含义是,任何旨在解决土壤侵蚀问题的政策干预都需要考虑到这些特征。

Farmers' Willingness to Pay for Improved Soil Conservation Practices in Kuyu Woreda, North Shoa Zone of Oromia, Ethiopia : Application of Contingent Valuation Method
Land degradation particularly soil erosion is one of the most severe environmental problems in Ethiopia. Achieving sustainable pathways out of land degradation problem and poverty require active participation of people in conservation practices and understand how farmers value the soil conservation. The objective of this study is to investigate the farmers’ willingness to pay for improved soil conservation practices on communal land in Kuyu woreda, North Shoa, Oromia Regional State of Ethiopia. Double-bounded dichotomous format of contingent valuation method is used to elicit respondents’ WTP. Data collected from 184 households were used for analysis. Both the Probit and Bivariate Probit models were estimated. The result of the study indicated that most of the respondents have perceived soil erosion problem and are willing to pay for conservation practices. Factors like sex, education, livestock, income, slope of land, perception, and the frequency of extension visit have a positive and significant influence on the probability of WTP for soil conservation. The study also shows that the mean WTP estimated from the Double Bounded Dichotomous Choice formats was 85.36 Labor days per annual. The total aggregate value of soil conservation in the study is 10,909,349 person days per annum (196,368,282 ETB) from double bound CVM. The study concluded that farmers have perceived soil erosion problem and they are willing to pay in terms of labor contribution for improved soil conservation practice. Therefore, policy implication suggested was any policy intervention designed to address soil erosion problems have needed to take in to account these characteristics.
