Conservation agriculture helps to maintain and improve the environment. Tractor use is substantially reduced when cultivation is eliminated, thus reducing emissions of greenhouse gases and other pollutants. Moreover, under zero tillage, soil moisture conservation and wind and water erosion are reduced because the soil surface is not plowed and residues, crowns, and roots from previous crops and pastures protect the soil. There are even cost benefits: it reduces the need for tractors and thereby lowers fuel and labor costs. Helping communities to adjust to the predicted changes and maintain agricultural production, which is extending a combination of technologies and innovative practices to the region’s farmers. Practising conservation agriculture helps in reducing plowing farmlands and leaving crop residue in the field for improved soil fertility and water conservation. The practice holds significant potential for the world’s dry areas, including the arid and semi-arid parts of the world. 

Conservation agriculture helps to reduce carbon foot-print for growing crops and this contribute eventually to mitigating climate change.
