Assessing the economic and environmental impacts of conservation technologies: a farm-level bioeconomic modelling approach uri icon


  • This chapter illustrates how a multiperiod bioeconomic household-level model, in which changes in resource quality have feedback effects on future land productivity, can be used to explore the economic and environmental impacts of natural resource management technologies and policies. This model is used to test the influence of land scarcity and asset poverty on incentives to undertake sustainability investments in Andit Tid, in the central highlands of Ethiopia. The results show how land scarcity could drive conservation investments, while poverty in vital assets such as oxen and labour could deter investments in land and water management. The welfare and environmental impacts are very modest but are highest when the conservation technology does not reduce short-term crop yields. Otherwise, the level of adoption of these technologies and their effects on poverty and soil degradation are significantly reduced even when family labour is not limiting
