    Les méthodes couramment utilisées pour l'évaluation des politiques publiques rencontrent deux principaux écueils. Le premier est d'analyser les relations de cause à effet uniquement à partir des opinions et avis des parties prenantes (stakeolders). Quand ces schémas de causalité mobilisent les théories en sciences sociales (theory driven evaluation), le second écueil est qu'ils sont rarement confrontés aux faits. Pour pallier cette défaillance de validité empirique, les approches evidence-based proposent de mobiliser des connaissances scientifiques testées empiriquement. Toutefois, même si ces approches sont répandues dans les domaines de l'éducation ou de la santé dans les pays anglo-saxons, elles s'avèrent encore très rarement utilisées dans les deux domaines d'application étudiés dans ce papier, le conseil en agriculture et l'agri-environnement. - The methods for the evaluation of public policies face two major limits. The first one happens when the schemes of causal relations involved in a given public policy are analysed only though the opinions and the knowledge of some stakeholders. When the description of these schemes is rather driven by some social sciences theories, a second limit may occur: the lack of confrontation with field observations. Both methods raise the question of their level of validity. In that respect, the EBP approaches proposes to ground the evaluation of public policies on scientific knowledge that rely on the best available empirical evidences. These approaches and the debates about them are well spread in the cases of health or education policies evaluation in Anglo-Saxon countries. However, they are much less implemented in the two cases studied in this paper: agri-environement and agricultural extension.
