The world human population is expected to increase from 7.7 billion in 2019 to 9.7 billion in 2050. To meet the world`s food demand, agricultural systems around the world are required to change from the current scenario to produce more food sustainably. In this regard Conservation Agriculture has been advocated as an agricultural system capable of attaining the sustainable intensification required to meet world food demand. Conservation agriculture helps to preserve the potential of soil biological features while also ensuring long-term productive capability. Conservation agriculture is a crop production system aimed at reducing the effort and cost of farming in a way that protects and improves agricultural soil productivity. In spite of its widespread promotion activities as a strategy to sustainably intensify agriculture in Sub-Saharan Africa, the adoption of conservation agriculture is still limited. Sustainable crop production techniques, including conservation agriculture, meet human food and fiber needs and improve the environment and natural resource quality. When its practices integrated together, several studies conducted on conservation agriculture have shown that CA has increased crop yields.In summary, conservation agriculture can be adopted for improved yield with sustainability and environmental safety in different parts of the world by appropriately implementing the basic principles.
