Using Agent-Based Modelling to Assess Scenarios for Enhanced Soil and Water Conservation in the Boset District, Ethiopia

Abstract

Thesustainabilityof theongoingCampaign-BasedWatershedManagement (CBWM)programinEthiopia is questionable due to poor planning and implementation of the Soil andWater Conservation (SWC) structures. This study uses an empirically based, agent-based model to explore the e ect of six scenarios on both area of land covered by, as well as the quality of SWC structures in three Kebeles (villages) of Boset District. The analysis revealed that integratingmultiple interventions enhanced SWCmost in all Kebeles. Furthermore, increasing the commitment of local government through capacity building generated most e ect and yet required the lowest investment. Motivating farmers, introducing alternative livelihood opportunities and establishing and strengtheningmicro-watershed associations had limited, but di erential influence on the outcomes across the Kebeles. However, all alternative scenarios had someadded value compared todoingbusiness as usual. Hence, in order to enhance the outcomes and sustainability of the ongoing CBWMprogram in the study area and other similar localities, it is crucial to pay much more attention to increasing the commitment of local government actors throughcapacity building. This empowers local government actors to (1) planandmoree iciently implement the program in consultation with other local actors, and (2) integrate locally sensitive need-based adaptation of the program.
