One of the major problems faced by our environment is crop residue burning, also known as stubble burning. Due to wide availability of modern tools and technologies for harvesting, a vast amount of residue is generated in the fields. The common practice to get the fields free from such residue is stubble burning. Such practices pose a wide variety of environmental problems. Residue burning emits carbon sinks in air causing pollution which is harmful for human-beings as well as flora and fauna. This study brings the problem of agriculture waste burning was 35 million tonnes in forefront. So, there is an immediate need to monitor such stubble burns so that effective measures could be taken to protect our environment from such a global menace. Burning of paddy straw results in nutrient losses, 385 million tonnes of organic carbon, 59000 tonnes of nitrogen, 20000 tonnes of phosphorous, 34000 tonnes of potassium. It also influences the nutrient condition of soil. The paddy stubble burn also has adverse effect on health also, so crop stubble management is necessary. Manual detection is not enough to monitor such widely spread problem. The efficient approach to detect stubble burned areas in various parts of Punjab using remotely sensed images and present government schemes is presented which could be utilized to prevent the large scale environmental degradation.
