Intérêt d'aménagements paysagers pour la biodiversité : exemple d'ingénierie agroécologique sur le domaine expérimental d'Epoisses (Inra Dijon)

subject

description

The biodiversity conservation is one of the major agricultural issues of the XXIst century. The intensification of agriculture and the redesign of the agricultural landscape (grouping of fields, …) lead to huge decreases or damages of semi-naturals habitats, known to promote biodiversity at the farm and the landscape scale, and now recognised as “topographic surface equivalence” in France.In the experimental site of Epoisses (INRA of Dijon), a study to design the landscape elements in favour of the biodiversity has been initiated. Improving the management of existing habitats (woods, hedges, ditches, sown grass margin strips), establishing hedges, flower strips, redesigning the field organization, etc… are studied options. These habitats, preserving biodiversity, have to maximise ecosystem services: for instance, the regulation of pests via the establishment of favourable habitats for auxiliaries. These habitats could lead to reduce pesticides’ uses in fields without decreasing the crop productions, by providing more natural regulation.
