The role of conservation agriculture in sustainable crop production: A review
Melkamu Dugassa Erena
The objective of this review paper is to organize relevant literature on roles of conservation agriculture in sustainable crop production using the results of researches undertaken in different parts of the world at different times. Relevant materials including journal articles reviews and short communications were used to organize the review. The world population is expected to increase from 7.7 billion in 2019 to 9.7 billion in 2050 which need additional food on the current demand. 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 helps to preserve the potential of soil biological features while also ensuring long-term production. Conservation agriculture is a crop production system aimed at reducing the effort and cost of farming in a way that protects and improves agricultural soils 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. Several studies conducted on conservation agriculture had shown that CA has increased crop yields under the implementation of the integrated practices of conservation Agriculture than each practice separately. Conservation agriculture could be adopted for improved yield with sustainability and environmental safety in different parts of the world if appropriately implemented.
