Workshop W2. Annual crops based systems
Chair
: Laure Hossard, INRA

Co-chair: Eric Scopel, CIRAD

This On-Farm Workshop was organized by the joint Research Unit on Innovation and development in the agriculture and the agrifood sector (INNOVATION - L. Hossard, J.C. Mouret, J.M. Barbier and S. Delmotte) affiliated to CIRAD, INRA and Montpellier SupAgro and the research unit Agroecology and sustainable intensification of annual crops (AIDA - K. Naudin and E. Scopel) affiliated to CIRAD.

It gathered around 35 participants, including organizers.

The visit took place in the Camargue area (50 km East Montpellier), where water management plays a crucial role in sustaining agriculture. This flat region, close to sea level, covers an area of 167 000 ha, with 60 000 ha for agricultural production and the remainder of protected natural areas. Flooded rice cultivation (up to 20 000 ha) consumes large amount of fresh water and has a significant impact as it dilutes soil salt concentrations. This water plays also an important role in the maintenance of the wetlands providing habitat to a great diversity of bird species. Rice is included in various cropping systems ranging from a few successive years of rice (in rotation with rainfed crops) to rice mono-cropping. However, continuous rice production uses significant quantities of agro-chemicals such as herbicides and fertilizers. These agro-chemicals disperse throughout the system and, given the high biodiversity value of the area, ecologists and citizens have long called for a reduction in the use of these inputs. Organic farming continuously develops since 10 years, with about 10% of organic rice.

The morning session was dedicated to the visit of the ‘Domain of Méjanes’, commented by the manager of the Domain M. Guillot. After a brief introduction of the history of the farm, owned by the Ricard family since 1939. M. Guillot presented the numerous activities of the farm domain. This domain combines touristic and agricultural activities, including bull rearing and cereals, grown partly in conventional and in organic. More specifically, the manager exposed its rice-based cropping systems in the field, with rice being a key-crop thanks to the fresh water used for its irrigation which maintains salt in the deep layers of the soil. The manager focused on the crop sequences and yearly field management, detailing some issues faced by the cropping systems (e.g. weed management, difficulty to grow some crops, e.g. soybean, etc.). Its presentation lead to questions and discussion on the topical cropping systems in Camargue between the participants, the domain manager and the INRA organizers.

After a train tour of the domain showing typical landscapes of Camargue, the morning session ended by presentations of the research activities of the two organizing units. The team of “Innovation” presented the history of research they carried out since 30 years in Camargue. The team of "Aida" presented their researches cropping systems design for sustainable intensification, by presenting the question of transition towards conservation agriculture in Madagascar.


The afternoon indoor session, focused on annual crops based systems, was dedicated to scientific presentations. These presentations encompassed the plot, farm and landscape scales, based on researches performed both in temperate (France, Italy, Netherlands) and tropical regions (Haiti). These presentations provided results based on different methodological approaches (field experiments, farm surveys, remote sensing, regional scenarios) for diverse crops (potato, rice, barley and sweet sorghum).
