"Future strategies for sustainable food security will need to get greater productivity from available land, labour, water and other resources, producing more food, as much as possible, with reduced inputs. The System of Crop Intensification (SCI) which emerged from an agroecological production strategy developed for rice in Madagascar in the 1980s has shown promise in various countries for raising the yields of diverse crops with less reliance on purchased external inputs, using less seed and needing less water because of enhanced root growth and soil improvement. Here we review the adaptation and application of SCI principles to increasing the production and availability of Ethiopia's most important indigenous grain crop, tef."
