Explanation:
Removal of more than 50 percent of crop residue can have negative consequences for soil structure, reduce soil organic carbon sequestration, increase water erosion, and reduce nutrient cycling and crop production, particularly in erodible and sloping soils, according to the study published in the March-April issue of ..
The majority of the Indian population is dependent on agriculture for livelihood. While agricultural activities are a source of income for around 70% of the Indian population and cater to the food and nutritional needs of the vast nation, the practice of burning residue of crops has devastating impacts on the environment. Burning the biomass residue is the easiest and most time-efficient mode of ensuring that the field is ready for the next cropping season in time. Needless to say that this practice is not environmentally sustainable. The emission of greenhouse gases like carbon dioxide, methane and nitrous oxide is one such consequence which has resulted in multiple environmentally degrading phenomena such as air pollution, global warming, smog and climate change. In order to cater to the food requirements of the 1.2 billion Indians and continue the dependence of the majority of them on agriculture, a balance needs to be struck so that the activity is sustainable and does not cause irreparable harm to the planet. A few such solutions are using the crop biomass as fodder for livestock, utilising the residue for power generation and converting the waste material to natural fuels. Not only will this reduce the plight of the already fragile and sensitive environment, but it would also lead to an increase in the income of the farmers. This would also be an effective waste management solution.
