Article
CONTEXT New types of farming systems have emerged in response to societal demands to reduce environmental impacts and dependence on non-renewable resources. These agriculture models can be classified according to their relative use of anthropic inputs or biodiversity and associated ecosystem services as agricultural production factors. All these m...
Article
Given the negative environmental effects of conventional agricultural techniques, the need for biodiversity-friendly agriculture systems that rely more on ecosystem services and less on chemical inputs is becoming increasingly urgent. In this paper, we focus on crop protection strategies that are alternatives to the use of pesticides. Diversificati...

Cropping system models are widely used tools for simulating the growth and development of crops at field scale. However, it is often difficult to satisfy their detailed input and output data requirements for a proper evaluation of model. In this study, expert knowledge data were used as alternative source to fulfil these data requirements. The mode...
Article
Plusieurs formes d’agriculture ont récemment émergé pour faire face aux externalités négatives de l'agriculture. Certaines visent à réduire les impacts. D'autres comme l'agroécologie propose de fonder l’agriculture sur les services écosystémiques. De ce fait, il coexiste actuellement deux grilles d'évaluation mal articulées caractérisant, l'une les...
Article
Full-text available
The general purpose of the primary and secondary data available in this article is to support an integrated assessment of scenarios of crop-livestock integration at the territorial level i.e. of exchanges between arable and livestock farms. The data is a result of a research collaboration between the scientist from INRAE, agricultural advisers from...
Chapter
We believe that approaches to landscape modification should explicitly include farmers, given their understanding of landscape management practices, and consider climate change, so that the landscapes are designed for future environmental conditions. Climate change is an existential threat to farmers and current patterns of arable agriculture, lead...

Full-text available
CONTEXT Crop diversification is now well-recognised as a strong lever to address the environmental challenges currently faced by agriculture. Connecting and fostering local exchanges between specialised arable crop and livestock farms can support the diversification of crops and relocate animal feeding with local protein (vs. soya supplements). How...
Article
Many studies have assessed the potential of agricultural practices to sequester carbon (C). A comprehensive evaluation of impacts of agricultural practices requires not only considering C storage but also direct and indirect emissions of greenhouse gases (GHG) and their side effects (e.g. on the water cycle or agricultural production). We used a hi...

In a changing world, identifying the drivers of vulnerability, resilience and robustness (VRR) of agricultural systems has become a major issue. We developed and applied a generic analytical framework to perform a systematic review of studies that quantitatively assess VRR of agricultural systems in temperate climate zones. After a thorough selecti...
Article
The scientific literature contains many studies of trade-offs or synergies between ecosystem services (ES); however, it is challenging to qualify and compare these studies. To address this issue, we developed a structured generic methodological classification (typology) of studies that focuses on relationships between ES. The method focuses on char...

Natural, semi-natural, and temporary grasslands harbour tremendous plant diversity. In this study, we identified various functional categories of plants to better characterise their levels of forage production and ecosystem services. The categories were defined based on species' growth rates (fast or slow) and timing (growth concentrated in the spr...
Conference Paper
Full-text available
Ecosystem services (ES) provided to farmers are now well-considered as natural-capital-based production factors. Developing them is a way to reduce use of anthropic inputs and so to develop a more sustainable agriculture. However, it is still a scientific challenge to evaluate quantitatively part of ES relatively of anthropic inputs in agricultural...
