“…In a study conducted by Peng and Sutton (1996) in UK ground arthropods increased in the alleys of alley cropping compared to arable control plot which was attributed to the improved microclimate due to the presence of trees. Increased arthropod diversity was also reported from alley cropping with alfalfa or smooth bromegrass (Bromus inermis L.) intercropped with black walnut in North America by Stamps et al (2002).…”

In temperate Europe alley cropping systems which integrate strips of short rotation coppices into conventional agricultural fields (ACS) are receiving increasing attention. These systems can be used for crops and woody biomass production at the same time, enabling farmers to diversify the provision of market goods. Adding trees into the agricultural land creates various additional benefits for the farmer and society, also known as ecosystem services. However, tree-crop interactions in the temperate region have not been adequately substantiated which is identified as a drawback to the practical implementation of such systems. In order to bridge this gap, the current paper aims to present a comprehensive overview of selected ecosystem services provided by agroforestry with focus on ACS in the temperate region. The literature indicates that compared with conventional agriculture ACS have the potential to increase carbon sequestration, improve soil fertility and generally optimize the utilization of resources. Furthermore, due to their structural flexibility, ACS may help to regulate water quality, enhance biodiversity, and increase the overall productivity. ACS are shown as suitable land use systems especially for marginal sites. Based on the available data collected, we conclude that ACS are advantageous compared to conventional agriculture in many aspects, and therefore suggest that they should be implemented at a larger scale in temperate regions.

“…The study site at Leeds University, UK, has been described in detail elsewhere (Peng et al 1993). Briefly, the agroforestry experiment consisted of four replicate blocks, each of 10,000 m 2 with four species of furniture timber trees (ash, cherry, sycamore and walnut) interspersed with hazel bushes and planted in rows (production hedge) 14 m apart.…”

“…The production hedge trees, which were planted in 1987, were 2.5-3 m high at the time of this study in 1990. The control areas had similar exposure to prevailing winds and similar soil type to agroforestry experimental areas, but were 20-30 m away from them (Peng et al 1993). The arable alleys between the production hedges and the arable control areas were sown with a pea crop (Pisum sativum L. cv.…”

“…Furthermore, agroforestry areas should provide habitats in which natural enemies of crop pests can shelter and overwinter especially after the crops have been harvested. The analysis of aerial samples from yellow water-pan traps in 1990 has supported this hypothesis (Peng et al 1993). This work examines (1) whether an agroforestry area can increase the activity of ground arthropods and (2) whether an agroforestry area can enhance the diversity of ground arthropods.…”

Comparison of the activity and diversity of ground arthropods in an agroforestry system in northern England was made using pitfall traps. The system consisted of production hedges of timber trees (ash, cherry, sycamore and walnut) interspersed with hazel bushes, arable alleys between the hedges and control areas. The most common taxa were more active during their abundant periods in the arable alley than in the adjoining control area containing the same arable pea crop. The diversity of ground arthropods was generally higher in the arable alley than in the control area. The production hedges could play a very important part in maintaining and enriching populations of polyphagous predators close to an adjacent arable crop.

“…En ce qui a trait à la biodiversité, diverses études ont montré que la diversité et l'abondance des populations aériennes d'arthropodes étaient plus élevées dans les SCI que dans les monocultures agricoles (Peng et al 1993, Stamps et al 2002, Akbulut et al 2003, Thevathasan et Gordon 2004. L'augmentation des populations de prédateurs des ravageurs des cultures pourrait favoriser la lutte contre ces ravageurs et limiter par le fait même le besoin de recourir à des pesticides (Stamps et Linit 1998).…”

RÉSUMÉLa plantation de feuillus représente une bonne opportunité pour intensifier la production de bois de qualité. En l'absence de revenus à court terme, ses bénéfices paraissent toutefois incertains pour les propriétaires privés. Les systèmes de cultures intercalaires (SCI), qui suscitent un intérêt croissant dans plusieurs pays tempérés, constituent une avenue à explorer pour dynamiser la plantation de feuillus et maximiser sa rentabilité, notamment dans l'écozone des plaines à forêts mixtes du Québec. Les résultats d'études récentes démontrent que les cultures intercalaires ne nuisent généralement pas à la croissance des arbres et peuvent même dans certains cas l'améliorer. En plus de présenter de multiples atouts environnementaux, notamment en ce qui concerne la fertilité des sols, la biodiversité et le paysage, les SCI s'avèrent souvent plus rentables que les systèmes conventionnels de plantation forestière. En revanche, les arbres peuvent entrer en concurrence avec les cultures pour la lumière, l'eau et les éléments minéraux, diminuant la productivité agricole. L'itinéraire technique propre aux SCI permet toutefois de maîtriser en partie cette compétition. Les perspectives de développement des SCI sont discutées dans le contexte biophysique et socio-économique propre à l'écozone des plaines à forêts mixtes du Québec.Mots clés : bénéfices environnementaux, bois de qualité, compétition pour les ressources, croissance des arbres, écozone des plaines à forêts mixtes, itinéraire technique, plantation de feuillus, productivité des cultures, rentabilité, systèmes de cultures intercalaires ABSTRACTHardwood plantations constitute a good opportunity to intensify the production of high-quality timber. However, in the absence of short-term investment returns, their economic benefits seem uncertain for landowners. Intercropping systems, which are stimulating interest in many temperate countries, could constitute an innovative way to increase the use of hardwood plantations and maximize their profitability, in particular in the mixedwood plain ecozone in Quebec. Results from recent studies show that intercrops do not usually affect tree growth and could even stimulate it in some cases. Furthermore, in addition to their various environmental benefits related to soil fertility, biodiversity and landscape, intercropping systems are quite often more profitable than conventional forest plantations. Finally, even though trees can compete with crops for light, water and nutriments, decreasing crop productivity, the technical itinerary specific to intercropping systems allows for the control of at least part of this competition. The development perspectives of intercropping systems are discussed, taking into account the biophysical and socio-economic context specific to the mixedwood plain ecozone in Quebec.
