Integration of the mitigation sequence (avoiding, reducing and offsetting impacts on biodiversity) into land planning policies
InSERCAT is an interdisciplinary research project, combining ecology and social sciences (sociology and law). The project is coordinated by the CESCO (MNHN) and counts three partner laboratories. It aims at analyzing the modality of integration of the mitigation sequence (avoiding, reducing and offsetting impacts on biodiversity) into land planning policies, assuming that this integration is necessary for its efficacy on the long term. The project will be based on document analysis, case studies (linear infrastructures in two French regions: Occitanie and Hauts-de-France), and on a sociological survey (including semi-structured interviews with stakeholders and observations in negotiating arenas).
The project follows on a previous research project on biodiversity offsetting (Compilsa 2014-2017), which showcased that the last step of biodiversity offset is actually dominant in the way the sequence is implemented, with a detrimental effect on activities aiming at avoiding and reducing impacts. It is also demonstrated that biodiversity offset generates an inflation of organizational costs linked to its application since 2007 in France, and finally a risk of concurrence with other biodiversity conservation policies.
The project InSERCAT therefore proposes to study the issue of balance between the three steps of the sequence in order to enhance its efficacy in the long term. For that, the project will explore internal issues: could it be expected that the development of tools would rebalance the mitigation sequence toward a better application of avoiding and reducing steps? The project will also explore external issues: would tools for implementation allow a better articulation between the sequence and other preexisting policies for biodiversity conservation, such as protected areas?
InSERCAT will run during 24 months and will contribute to the production of knowledge targeting both researchers and operational actors, in order to promote an integrated and robust implementation of the mitigation sequence.
