In introducing of new agroecological practices, it is important to have knowledge on the socio-economic impact such as crop yield, energy and economic balances in order to incorporate in the decision-making. The new issue of the newsletter is investigating how to determine the costs and benefits of several measures enhancing biodiversity. The objective is to identify whether the 5 main measures that were selected as representative of French crop production systems are economically viable for farmers, in terms of implementation costs and income benefits for the farmers. The study focused on 3 off-crop measures: hedges, flowering strips, grassy margins; and 2 in-crop measures: cultivar mixture and direct sowing.
