Sustainability of biophysical soil and water conservation measures undertaken on communal land remains a challenge. This research was conducted in the two watersheds of Legambo district, Ethiopia, using a conservation project implemented as disaster risk reduction and adaptation to climate change. The study examined relevance and appropriateness of conservation measures and identified factors affecting sustainability. Findings show that population growth is high and crop production is the major source of income for all households. Crop income levels varied significantly (P<<0.01) with wealth status of households. Droughts, floods, crop diseases and frost are hazards that frequently occur in the area. Some conservation measures implemented were considered by communities as inappropriate. Low community participation, poor planning and unclear objectives and use rights, weak enforcement of by-laws and lack of maintenance of structures are the major challenges. Integrating family planning, enhancing participation of women, clarifying responsibilities and benefit sharing arrangements, enforcement of rules and building capacity are suggested to improve effectiveness and sustainability of conservation measures / Environmental Sciences / M.
