Approche géographique des approvisionnements en plaquettes forestières des chaufferies du secteur collectif/tertiaire : application au pays Loue-Lison et à la communauté d'agglomération du grand Besançon

Abstract : In a context of strong increase of fuelwood demand in the collective sector, the supply issue becomes central to all stakeholders, raising many issues relating to land and forestry planning, local development, environment ... Meanwhile, questions emerge: how much energy can be mobilized sustainably? Does the spatial and structural configuration of forests influence the supply process? Do we seek to minimize transport distances? Can we observe spatial competition between the boilers ? To understand the current organization of supplies, we analyzed two sets of data traceability of wood chips. Then, we have developed a model of local supply basins, considering constraints of renewability of the resource, and conflicts of use, by combining various information sources: vegetation index derived from satellite imagery, forest mapping and production tables. The objective of this approach was dual : to determine the quantity of forest chips workable on a territory, and to highlight the spatial competition between the different basins supply, and the contribution of different tree species. This has enabled to show the importance of the energy potential of isolated trees, to our knowledge not previously evaluated in a sub-regional scale.
