Abstract

[fre] Le présent travail appliqué à la Tunisie, part d'un double constat relatif, d'une part, à la gravité de l'érosion et, d'autre part, à l'importance des dépenses publiques en matière de conservation des eaux et du sol visant à atténuer ce phénomène. La contradiction de ce double constat et la divergence des résultats obtenus par l'adoption de ces aménagements de conservation constituent le déterminant principal pour la remise en cause de l'efficacité de cette intervention publique. L'évaluation quantitative de l'impact de ces aménagements sur le rendement, le système de production et par là sur la rentabilité des capitaux investis ainsi que sur l'érosion constituent, donc, l'objectif primordial de ce travail. L'approche bio-économique qui couple l'emploi d'un simulateur biophysique à un modèle d'optimisation économique est avancée comme une meilleure méthode pour juger cette efficacité. [eng] A bio-economic model for analysing the impact of soil and water conservation policies applied to a tunisian farm . The present study applied on a big farm in Tunisia, based on a double observation relative to the gravity of the erosion and, on the other hand, the importance of public expenditures for water and soil conservation aiming to lessen this phenomenon. The divergence of results obtained by the adoption of conservation techniques constitutes the principal reason for questioning of this public intervention. The quantitative evaluation of the impact of these conservation on yield, the farming system and on the profitability of capital invested as well as on the erosion constitutes, there fore, the essential objective of this study. The bio-economic approach combining the use of a biophysical simulator and an economic optimization model is proposed as method to judge this efficiency.
