Pastoralists’ willingness-to-pay for rangeland improvement: A case of Yabello District, Southern Ethiopia
Keywords:
Binary logistic, bivariate probit, contingent valuation, degradation, pastoralists, willingness to payAbstract
Rangeland degradation remains a major concern for pastoralists’ livelihoods in Ethiopia and need to be properly managed and utilized to optimize the benefits to the country at large. Several studies about rangeland resource management in Ethiopia had hitherto focused on the biophysical aspects without considering the societal and cultural needs of the people. Pastoralists’ demand for the improvement using acceptable environmental valuation techniques remained a research gap. This study aimed to estimate pastoralists’ willingness to pay (WTP) for the rangeland improvement in Yabello District, southern Ethiopia. A total of 172 households from the two Kebeles were randomly selected. Bivariate probit and binary logistic models were used to estimate mean willingness to pay (MWTP) and factors influencing pastoralists’ WTP respectively. The estimated MWTP for the improvement was 11.86 man-days/month, which is equivalent to 830.2 ETB/month ($17.934225). The aggregate WTP for the improvement was 38,426 man-days/year, which is 2,689,820 ETB/year ($58,117.837). Sex, age, family size, major livelihood activities, livestock holding and initial bid value have significant influence on pastoralists’ willingness to pay. These factors need to be considered in policy-making regarding rangeland rehabilitation projects involving pastoral communities. Furthermore, we derived entry points for future research in rehabilitation of degraded rangelands in Ethiopia.
