Resumo: Designing agricultural systems targeting an increase of natural regulations and a decrease of pest populations should be based on the optimization of various ecological services and biodiversity by modifying deeply the composition, structure and organization of agroecosystems. An agroforestry system combining fruit trees, vegetables and wild trees and shrubs is one possible option. Key challenges are to find out (i) a compromise between economic/technical constraints and ecological processes stimulating natural regulations and (ii) to test spatial combinations of vegetation. We explored the basic ecological principles necessary for the functioning of such cropping systems and elaborated an approach enabling the design and monitoring of complex horticultural agroforestry systems, at the level of a production unit. We present a co-design research project for a 4 ha pilot farm unit in the periurban area of Avignon, France (La Durette). We elaborated over two years different possible spatial arrangements and prototypes through participative discussions involving scientists, advisors and farmers. We progressively evaluated different combinations and ratios of fruit and vegetable production through calculation of expected yield, operational costs and income over ten years and through an expert evaluation of the labour time requirements. We also studied different possible spatial arrangements by modelling the impact of canopies on the available light for annual crops . This led to proposals for a sustainable and viable crop production system managed by 2 farmers. The different calculation tools could be further used to elaborate whole farm planning guides for horticultural agroforestry farms under temperate climate.
