Valoriser les services écosystémiques de la biodiversité pour une agriculture plus durable, questions et enjeux liés à la variété des pratiques des agriculteurs à l’échelle des paysages : une étude de cas dans les coteaux de Gascogne

Abstract : Front to biodiversity loss of agricultural landscapes, conservation policies are developed to modify agricultural land-use practices. However, farmers' practices are influenced by many factors. Our study aims to explore the relationships that may exist between their land management practices and their representations of landscape operation, in order to help to coin courses of action for landscape management favorable to biodiversity. Our approach is based on two separate analyzes based on two surveys of a sample of thirty farmers in the French Coteaux de Gascogne. We assessed the diversity in their individual land-management practice (for cropland and semi-natural landscape components) from typologies built using multivariate statistical analyses. We then compared the farmers’ landscape representations according to their type of land-management practices, using a statistical and a qualitative analysis of their mental models of the landscape. Differences in the contents and complexity of these models, and results of their statistical comparison, revealed that farmers’ representations of landscape varied according to their types of land management practices. These results suggest that there is actually a connection between what farmers think about landscape function and what they do in their land management.
