Public agro-environmental policies and individual choices in the reduction of plant-protection products’ usage
Irstea and Bordeaux Sciences Agro have an opening for a post-doctoral position within the framework of the PhytoCOTE Project whose overall objectives are to evaluate plant protection products use in agricultural systems, their potential transfers on ecosystems and the effect of changes in plant protection practices. Concerning the social and human sciences part (economics), the aim is to evaluate to what extent economic, structural and behavioural factors can impact changes in the use of pesticides in viticulture.
The objective of the post-doctoral work is to highlight the relations between wine-growers’ individual choices and public environmental policies such as the Grenelle Environment Forum and the Ecophyto Plan, in relation with another 2 years post-doc focused on the analysis of several different wine production systems and on the analysis of practices at field scale .
– Carrying out a state of the art on alternative production systems to be evaluated.
– Analyzing the individual case of producers at studied site as regards their approach to reduced use of phytosanitary products. The VINEPA model will be used for this site.
– Initial conclusions will help to design and analyze a certain number of theoretical scenarios for change at the studies sites. The respective costs and advantages of those strategies aiming to reduce pesticide use and their pressure on the environment (choice of less harmful active substances, spraying technologies or others such as the adoption of organic viticulture) will be evaluated within the framework of a cost-effectiveness analysis. The environmental effectiveness of these strategies will first be evaluated according to the EIQ environmental indicator and more particularly the EIQ-Field.
The catchment area of application is called the Bassin Versant Expérimental (BVE) at Marcillac, dominated by the growing of wines of the Blaye and Côtes de Bordeaux appellations. All the producers possessing a plot in the catchment area have been the object of preliminary studies enabling technical and economic data of the farms to be collected along with information on their phytosanitary practices.
