Que sait-on aujourd'hui des impacts, positifs et négatifs, de l’agriculture sur la biodiversité ? Quels services la biodiversité peut-elle apporter à l’agriculture, et à quelle hauteur de performance ? Comment favoriser au champ les synergies entre agriculture et biodiversité ? Quels instruments de politiques publics, économiques et juridiques, faut-il mettre en place pour promouvoir ces interactions ? Ces questions ont mobilisé un groupe pluridisciplinaire d’experts (écologues, agronomes, microbiologistes, spécialistes de santé végétale, économistes, juristes, sociologues), de différentes institutions (Inra, CNRS, IRD, Universités, Ecoles supérieures agronomiques) en France et à l’étranger

Ecosystem services in a general equilibrium setting: the case of insect pollination Inra
Gallai, N.; Figuieres, C.; Salles, J.M.; AERE, Association of Environmental and Resource Economists (USA); EAERE, European Association of Environmental and Resource Economists (ITA).
Insect pollination is widely used for agricultural production and contributes significantly to the global value of crops. In this study, the impact of insect pollinators on the social welfare is assessed within a general equilibrium. What would be the general consequences of a production loss due to pollinators decline? How are changes in profits distributed between producers of pollinated goods and other producers? These questions are studied within two alternative distribution of property rights over the firms: the case when agents possess and equal share of the firms (egalitarian ownership structure) and the case where each agent possesses one firm (polarized ownership structure). For each case, we consider the case when agent and firms are homogeneous,...
