During the last 40 years, despite a large development in the use of crop protection practices, which rely heavily on synthetic chemicals, crop losses have not significantly decreased. Because of human population growth and growing threat on ecosystems health, new strategies are urgently needed for both an economically and ecologically sound crop production. The propensity of certain soils to limit plant disease incidence due to particular biological or physical properties is known as soil suppressiveness. In this project, we aim at assessing in what extent the suppressiveness concept may be relevant to landscape structure and composition, and thus applied against aerial pests. Landscaphid aims at (i) addressing whether landscape suppressiveness hypothesis is valid, by identifying the landscape factors favoring or limiting pest risk and biological control; and (ii) understanding the functioning of this suppressiveness, by researching the ecological processes involved at all ecological levels (from genes to community). By integrating all this information, we will finally (iii) propose landscape management tools to support the agricultural landscape suppressiveness.
