The purpose of this study is to investigate the preferences of people in the Bale Eco-Region (BER) for better ecosystem services and to calculate their mean Willingness to Pay (WTP) for selected attributes of conservation practices to maintain watershed's ecosystem functions, using a choice modeling approach. Results from reforestation attributes revealed that the average WTP for reforestation characteristics were 3,053 ($145.38), 2,516 ($119.83), and 1,827 ($87) Ethiopian Birr (ETB)/year for higher, medium, and low impact improvement scenarios respectively, to midland communities. Lowland respondents' mean WTP for exclosure attributes were estimated at 882 ($42), 1,558 ($74.19), and 2,383 ($113) ETB yearly for low, medium, and high impact improvement scenarios respectively. This indicates that respondents from both lowland and midland communities are willing to spend a substantial amount of resource and time (measured in terms of money) on to improve ES in the BER. The study provides valuable input to carry out a cost-benefit analysis of possible interventions conserving natural resources in the BER. Moreover, using this study was an important step for initiating the process of Payment for Ecosystem Services in the BER where local communities, in Ethiopia and beyond could contribute to rehabilitating Ecosystem Services.
本研究的目的是利用选择建模方法,调查巴勒生态区(BER)的人们对更好的生态系统服务的偏好,并计算他们为维持流域生态系统功能的选定保护措施属性的平均支付意愿(WTP)。造林属性的结果显示,对于中部地区社区,在高、中、低影响改善情景下,造林特征的平均支付意愿分别为每年3053埃塞俄比亚比尔(ETB)(145.38美元)、2516埃塞俄比亚比尔(119.83美元)和1827埃塞俄比亚比尔(87美元)。低地受访者对围栏属性的平均支付意愿估计分别为每年882埃塞俄比亚比尔(42美元)、1558埃塞俄比亚比尔(74.19美元)和2383埃塞俄比亚比尔(113美元),分别对应低、中、高影响改善情景。这表明,低地和中部地区社区的受访者都愿意花费大量资源和时间(以金钱衡量)来改善BER的生态系统服务。该研究为开展BER自然资源保护可能干预措施的成本效益分析提供了有价值的投入。此外,利用这项研究是在BER启动生态系统服务付费进程的重要一步,在埃塞俄比亚及其他地区的当地社区可以为恢复生态系统服务做出贡献。
