Mediterranean silvoarable systems in France

Description of system

The high seasonal variability of rainfall in the Mediterranean areas of southern France limits arable yields. There are periods of high rainfall in the autumn, and periods of water shortage in the spring and summer. In this situation, in areas where there are deep soils, that are able to retain water, silvoarable agroforestry (tree lines within the field) can improve water infiltration, limit soil evaporation, and limit crop water requirements.

Initial stakeholder meeting

The first meeting of the stakeholder group was help on 2 October 2014, and included visits to INRA Mauguio experimental station and the silvoarable systems at Restinclières. The research at Mauguio includes varietal selection of cereals. The systems at Restinclières include combinations of cereals with walnut, cereals with poplar and vineyard systems. The farmers who attended perceived that the key positive aspects of silvoarable agroforestry were income diversity, crop production, enhancement of biodiversity and wildlife habitats, and soil conservation. Key negative issues related to the business opportunity, cash flow, and crop losses from slugs, and wild deer and boars. A potential area for research is the selection of durum wheat varieties suited to agroforestry conditions.

An initial report was produced in October 2014.

Download the initial research and development protocol

This stakeholder group has produced two protocols: the first is focused on the selection of durum wheat varieties for agroforestry and the second is focused on weed management in silvoarable systems.

Two system description reports providing an update on the selection of durum wheat varieties and weed management were produced in January 2016.
