The FIE combines different modes of operation. He intervenes mainly by calls for projects. Other mechanisms are possible:
- compensation of local communities
In the case of damage caused by wild animals in particular, the FIE is the structure responsible for examining the requests for compensation. The thematic committee "Forest and Wildlife" is responsible for examining these requests.
- The financing of emergency actions (environmental remediation)
In the event of a natural or industrial disaster, within the framework of the thematic fund "Reactions to natural and industrial disasters".
- A mechanism for investigating requests received on a case by case basis
It is a suitable mechanism for complex requests from large players, for example green investments in the productive sectors. This mechanism also makes it possible to respond to the limitations of the demand-driven approach because the FIE must be able to finance (i) certain large-scale actions that exceed the implementation capacities of local actors or that will not be requested by anyone, (ii) ) pilot projects that lead the way in new areas.
- The matching of existing funds or financial mechanisms
The FIE can delegate the management of part of its financing, with precise specifications. This is an opportunity to study for collaboration with the Permanent Fund for the Development of Territorial Communities (FPDCT) or the National Fund for Research and Innovation for Development (FONRID) for example.
- Financial incentives in the form of an interest rate subsidy or bank guarantee
- Competitions of best practices, aiming to give priority to the actors who have developed innovative or effective practices of sustainable development in their functioning, which encourages and also allows to communicate on these practices and facilitate their diffusion.
The choice and the exact combination of these different modes of intervention are decided according to the objectives set by the FIE, the domains and actors targeted, and the sources of funding.
