Using the several site parameters from the LTER ‘Plaine & Val de Sèvre’ dataset, this important gap will be covered, using an expanded bioeconomic modelling approach in order to integrate the complexity of the ecological interactions, farmers’ behaviour characteristics and economic drivers. It will be addressed important questions, such as how different cropping systems or management strategy could be adapted in order reduce anthropogenic inputs and so preserve higher biodiversity while maintain agricultural activity viable and profitable. This is a vital challenge to ensure the sustainability of both: agriculture and ecosystem services. The ultimate goal is therefore to develop tools that could provide a sustainable ecosystem services without disregarding farmer objectives.
Designing cropping systems that maintain or increase yields while reducing the reliance on agro-chemical inputs is the main challenge that agriculture is facing today. Herbicides represent the majority of pesticides used in annual crops in many countries, making weed management one of the main obstacles to meeting this challenge. It is imperative, therefore, that the consequences of agricultural management on weed diversity/abundance and crop production are investigated in contrasting situations. However, despite an extensive literature, weed species assembly in agroecosystems remains to be fully understood. Weed community assembly results from interactions between various ecological processes across a range of spatial and temporal scales and management through disturbances regimes and resources (e.g. nitrogen and water) levels at the field scale. DISCO-WEED aims to provide a conceptual framework based on ecology and agronomy to quantify both the relative contribution of agricultural and ecological processes in weed species assembly and their impact on weed-crop interactions. Our consortium partners combine expertise in agronomy, ecology, and spatial statistics. DISCO-WEED will use a large number of databases, spanning several countries and weed species pools, gathering data on weed flora, agricultural practices and for some crop yield, collected at all spatial scales from 1m² to the national scale over nearly 4,000 agricultural fields these last 15 years.
A multi-species / mult-scales project aiming at quantifying the potential effects of infrastructures (highways, wind farms, buildings) on the breeding biology and habitat selection of 3 patrimonial species (Stone Curlew, Little Bustard, Montagu's Harrier)
