ABSTRACT

Conservation agriculture is practiced globally on an estimated 155 million hectares in all continents and agricultural ecologies. The effects of climate change also need to be considered along with other evolving factors that affect agricultural production, such as changes in farming practices and technology. Humans have been influencing the climate since the start of the Industrial Revolution. Aerosols are less well-known than greenhouse gases. Some aerosols have a cooling effect on the climate, others have a warming effect. Climate change mitigation generally involves reduction in anthropogenic emissions of greenhouse gases. Carbon dioxide is the primary greenhouse gas that is contributing to recent climate change. Methane is produced through both natural and human activities. Nitrous oxide is produced through natural and human activities, mainly through agricultural activities and natural biological processes. Permanent crop cover with recycling of crop residues is a pre-requisite and integral part of conservation agriculture.
