Sujet de thèse : Introduction of sunflower in crop rotations: What economic criteria for public and private Strategic Action?

La thèse en deux mots : « The objective is to examining the public or private initiatives for the adoption of sunflower in the rotations systems, while taking into consideration the environmental indicators and more specifically the pollination activity.»

Résumé du papier : Recent years have witnessed a substantial decline of pollinators in Europe. This phenomenon has been partly associated with changing farm practices and in particular with the increase of pesticides use. These practices have particularly affected the insect pollinators and more specifically the bee populations. The bee’s pollination plays a crucial role in the crop production and especially in the hybrid sunflower (Helianthus Annuus) seed production, which is an economically important industry that supports other agricultural sectors. In this paper, we developed an ecological-economic model of a single farm output, assuming that both pest control and pollination are essential inputs, for two farm-types in South-Western France. According to different agronomic contexts, different levels of subsidies or penalties can be efficiently targeted to the implementation of new farming practices. The results depend on farm characteristics, agri-environmental indicators, labor allocation capacities and also farmers’ perceptions of yield risks.
