Article
CONTEXT Although cereal–legume intercropping is a recognized approach to improve crop production sustainability, its uptake on European commercial farms remains slow, due to numerous questions raised by the introduction of intercrops in a cropping system. Co-design workshops allow multiple scenarios to be explored without risks. They favor identifi...
Chapter
IPM promotes the design of resilient systems that reduce both pest attacks and damage to cultivated plants. It is based on practices that foster plant tolerance and the control of pests by their natural enemies. The challenge is to combine those practices in a coherent system that should associate the benefits or even develop synergies among their...
Book
Full-text available
In this chapter, we first describe and illustrate various agronomic IPM practices (Section 2) and plant diversity-based practices (Section 3) with detailed examples from fruit production, mainly on pome and stone fruit. We then provide some insights on the design of cropping systems that combine the above-mentioned IPM practices at field, farm and...
Article
CONTEXT High pesticide use causes environmental and human health hazards. Yet, the change to alternative crop protection practices faces a web of interacting barriers that results in a sociotechnical lock-in. Designing “coupled innovation” has been proposed by agricultural scientists to overcome the barriers that prevent change in practices. Couple...
Article
Cereal-legume intercropping is known to improve the sustainability of crop production. However, it remains uncommon on commercial farms in Europe due to a number of socio-technical lock-ins and the many practical issues raised when integrating intercrops in cropping systems (e.g. which species, cultivars, sowing densities). Crop modelling is an opt...
Article
Western agricultural practices for crop protection are still heavily dependent on pesticides, even though they cause major human health and environmental hazards. In France, public incentives for pesticide reduction have failed to achieve their goal, and agroecological practices are still seldom implemented. In this study, we hypothesized that a sy...

Article
French and EU policies have been only partially successful in promoting the restoration of groundwater quality. The currently proposed measures are scientifically valid but ineffective in encouraging farmers to change their practices over the longer term. Participatory approaches have been developed for co-designing scenarios at cropping system or...
Presentation
Sheltered vegetable cropping systems in South-East France are locked-in around short crop rotation and radical soil disinfection techniques. We worked on a methodology to codesign with stakeholders the solutions to overcome this lock-in. We present here the first results.
Conference Paper
Full-text available
The development of intercropping in European arable farms progresses slowly. A practical challenge to a larger spread of intercropping is the design of optimized and locally-adapted management practices. In the field, there is a diversity of farmer constraints and objectives, and hence of possible combinations between species and cultivars, sowing...
Article
Sustainable cropping systems that balance agricultural productivity and ecological integrity are urgently needed. Overreliance on soil tillage and herbicides to manage weeds has resulted in a number of major environmental problems including soil erosion and degradation, biodiversity loss, and water quality impairment. Combining organic farming and...
