Résumé
This report proposes a method for assessing economic impacts of water and soil conservation policies at farm level, in Tunisia. It is composed of five phases. 1) Takeover of the study site, 2) characterization of agricultural soil and water uses, 3) Identification and modelling of impacts of soil and water conservation measures at farm level, 4) Accompanying measures, and 5) Synthesis. At each step the proposed methodological elements are illustrated with examples from Tunisia or similar pedo-climatic and socio-economic contexts.
