Impact of crop residue burning on environment and human health

Abstract

The increase in agricultural production in India has contributed significantly to increase in GHG concentration in the atmosphere due to excessive tillage, use of fertilizer and improper crop residue management practices. The mechanization of Indian agriculture has also resulted in development and adoption of combine harvester, which leaves residue of harvested crop in the field. This crop residue is normally burnt in the open field leading to rapid GHG emissions and disturbing soil’s natural properties that contribute adversely to the fertility of the soil. It also affects human health in a number of ways. There is a need to discourage burning through Government incentives and technology transfer. Efficient machinery developed should be popularised and researcher’s farmers interactive sessions should be held for discussion of pros and cons of burning practice.
