Abstract – The evolution of natural ecosystems is controled by a high level of biodiversity, In sharp contrast, intensive agricultural systems
involve monocultures associated with high input of chemical fertilisers and pesticides. Intensive agricultural systems have clearly negative
impacts on soil and water quality and on biodiversity conservation. Alternatively, cropping systems based on carefully designed species mixtures
reveal many potential advantages under various conditions, both in temperate and tropical agriculture. This article reviews those potential
