A dynamic bio-economic model is used to show that, without technological and policy intervention, soil nutrient balances, income and nutrition could not be substantially or sustainably improved in a highland area of Ethiopia. Although cash incomes could rise from a very low base by more than 50%...

A dynamic bio-economic model is used to examine natural resource use, the resulting nutrient balances and economic outcomes in a poor country under a range of technological and policy intervention scenarios.
