Determinants of the reduction of herbicide use through Agricultural Environmental Schemes

subject

description

EAGESTAD INRA; Several public policies have been set up at the regional, national and European levels to reduce the negative impacts of intensive agriculture. Here, we wonder what are the determinants – social, economic, etc. - of the reduction of herbicide use? We focus the determinants of farmers' adoption of agri-environmental schemes (AES). Many factors influence farmers’ adoption. First, the importance of farm incomes in total incomes have been shown to be negatively correlated to AES adoption. The same conclusion was observed with the total family time spent at work. A determinant which is important for the probability to contract is the total farm labour supply per year (family and non-family labour): the more workforce farmers already have, the more they contract. However, although several studies have investigated the determinant of AES adoption, others determinants such as the level of debts remain to be investigated. Moreover, determinants have generally been investigated independently without looking at social, economic and environmental motivations altogether. After conducting a literature review, we will therefore carry out an econometric analysis to evaluate the influence of a wide range of determinants based on survey questionnaire sent to farmers. In this presentation, we will present first results.
