The study develops a bio-economic modelling framework that permits simultaneous assessment of the effects of technology change and policy measures on household welfare and agro-ecological sustainability indicators. The bio-economic modelling framework expands traditional farm household models to incorporate direct consumption utility functions, to allow for multiple objectives and to permit a meaningful interface with biophysical process models. The resulting model combines econometrically estimated equations in a mathematical programming framework. Model outcomes are analysed using metamodelling tecyhniques.
The bio-economic modelling framework is relevant for policy analysis related to resource degradation in developing countries. The model is applied to Cercle de Koutiala in southern Mali for specified research questions. Model results indicate that the model is robust and relevant for policy dialogues.
Application of the model to assess the potential of new technology in the household setting indicates that the problem of soil mining cannot be reversed. With the present alternative technologies, there is only limited scope for policy induced improvements in sustainability indicators.
