| Sumario: | In the coming decades, resource constraints over water, soil quality, biodiversity, livestock feed, and feed quality will increasingly negatively affect agricultural systems. Sustainable agroecosystems are those that tend to have a positive impact on natural, social and human capital. Sustainable intensification (SI) is defined as a system where agricultural performance is increased without adverse environmental impact and without the conversion of additional nonagricultural land into production. In much of Africa, any currently non-agricultural lands are likely to be marginal (Van Ittersum Martin, 2016), implying that their conversion to cropped lands would be associated with severe land degradation and unsustainable trade-offs. Unfortunately, for mixed farming systems, the synergies and trade-offs have not been adequately documented.
