“…1). Morris and Garrity (1993) indicated that the water use of monocropped and intercropped plants is almost similar in arid environments due to the high soil evaporation under monocropped situations. The results contrasting with the present study may be caused by the different environmental condition (humid region) in which this experiment was conducted.…”

“…Other studies revealed more depressed yield of pearl millet near trees/shrubs than in more distant positions; they ascribed this depression to competition for limited soil water (Wezel, 2000;Bayala et al, 2002). The performance of companion crops in intercropping is determined by competitive use of the limited resources (Ofori and Stern, 1987;Morris and Garrity, 1993). For example, Nelson and Robichaux (1997) indicated that cowpea cultivars with a spreading habit have a higher suppressive effect on pearl millet yield than bush-type cultivars.…”

“…In China, water use efficiency in a potato-bean intercropping system was 13.5% greater than in monoculture (10.15 kg/m 3 ) [30]. Morris and Garritty [51] found that water-utilization efficiency by intercrops greatly exceeds that of crops grown in monocultures. They do so by promoting the full use of soil water by plant roots, increase the water storage in root zone, reduce the interrow evaporation, but also by controlling excessive transpiration, and by creating a special microclimate advantageous to plant growth and development.…”

Modern agroecosystems require systemic change, but new redesigned farming systems will not emerge from simply implementing a set of practices (rotations, composting, cover cropping, etc.) but rather from the application of already well defined agroecological principles. These principles can be applied using various practices and strategies, each having different effects on productivity, stability and resiliency of the target farming system. By breaking the monoculture nature of farming systems, agroecological diversification aims at mimicking ecological processes leading to optimal nutrient cycling and organic matter turnover, soil biological activation, closed energy flows, water and soil conservation and balanced pest-natural enemy populations. All these processes are key for maintaining the agroecosystem's health, productivity and its self-sustaining capacity. By enhancing functional biodiversity, a major goal of the conversion process is achieved: strengthening the weak ecological functions in the agroecosystem, allowing farmers to gradually eliminate inputs altogether by relying instead on ecological processes and interactions.
