The study looked at how technology and policies can improve soil health, income, and nutrition in a highland area of Ethiopia. By using new farming methods and land management practices, cash incomes could increase by 50% and soil erosion could decrease by 28% over twelve years. This could also help meet daily calorie needs from on-farm production and improve nutrient balances in the soil. However, these gains could be affected by a faster population growth rate. To make these improvements sustainable, better land tenure policies, access to credit for farmers, and a shift in livestock management practices are needed.
