ABSTRACT
In the Maghreb region, productivity of rainfed and irrigated crops has been threatened due to social and technological constraints, water scarcity, low and variable rainfall, reduced soil fertility and quality, and improper agricultural management. This chapter aims to collate and synthetize the available information on research in relation to improvements in achieving sustainability and mitigating anthropogenic climate change—through adoption of no-till (NT) systems over existing conventional agriculture systems (e.g. crop productivity, soil quality, erosion control, and carbon emissions and sequestration). It builds upon some previous review articles which have already deliberated the differential effects of NT versus conventional tillage on soils, crops, environment and the farmer's economy; it also includes the expertise of different researchers through their publications and projects. Conversion to NT systems for management and control of soil erosion can also reduce losses of SOC in water- or wind-transported sediments and contribute to reducing emissions and sequestration of carbon.
