Impact of Crop Residue Burning:on Environment and Human Health

摘要

According to the study conducted by the National Physical Laboratory, New Delhi in 1994, Madhya Pradesh stood third in the list of the crop residue producing states of India with a production of 18.84 million tonnes of rice and wheat residues. As anyworthwhile use of such a high quantity of crop residue is not introduced to farmer, lack of user-friendly recycling tools, expensive labour and moreover farmers in a hurry to sow the next crop; the practice which is widely accepted is the burning of thiscrop residue in the open field. Wheat and rice crops are major contributors to burning of crop residues in open field with small contributions from sugarcane, cotton, jute, millets, maize, rapeseed and mustard crops. The GHG emission due to crop residueburning was around 5 Mt CO, eq in 1995-96 and within a decade it increased to more than 7 Mt C07 eq in 2006-07.
