Abstract: Prosopis juliflora, which is an alien tree species in Ethiopia, has invaded over 360,500 ha of land in the Afar region of the country and is threatening pastoral livelihoods. We conducted a contingent valuation study to assess rural households’ willingness to contribute in cash and labor to mitigate P. juliflora invasion in three districts of Afar. Results show that about 84% of the respondents prefer an intervention involving complete eradication of P. juliflora. The lower and upper bound median willingness to contribute to this intervention were 9.97 and 13.42 USD/household/year in cash and 30 and 43 days/household/year in labor. Off-farm income and P. juliflora invasion levels on pasturelands are among the factors affecting willingness to contribute to the mitigation of P. juliflora invasion. Incentives to local people and having a proper institutional setup that involves local culture and institutions are important for mobilizing people on a voluntary basis for mitigation of P. juliflora invasion.
