Implications of agricultural policies on the environmental services provided by livestock farms: an economic and extended accounting approach

The project aims to identify and assess the environmental performance of livestock farms, in relation to their economic performance. This project follows a partnership research with Cerfrance Bretagne, which allows the use of private accounting data from dairy cattle farms in the region. The challenge of these initial works was to provide farmers and dairy market operators with tangible elements of environmental service production and the production costs associated with these services. Following these works, and for the thesis, we plan to use empirical approaches (treatment effect methods, panel models) and theoretical models (total factor productivity models) to identify the specific effects of environmental performance on economic performance indicators. Depending on the available data, we consider research on different types of services: greenhouse gas emissions, water quality (nitrogen, phytosanitary products), biodiversity. Our hypothesis is that measuring economic and environmental performance to "prove" environmental action can help both in the transparency of commercial relations within agricultural sectors and in the design of public action, particularly agricultural policies, in the long term. For this, a part of the thesis will be devoted to the prospects of integrating the remuneration of environmental services, in a results-based approach, in the development of long-term public policies.
