Biomass burning ia a major contributor to the atmospheric carbon budget and increases the concentration of many trace gases apart from the adverse effects on soil properties. However, in manyy parts of India, crop residue burning is a recurrent and widespread practice for disposal of the residues after harvest of the previous crop to facilitate sowing of the succeeding crop. The residue burning on a larger scale also leads to severe atmospheric pollution.

Order of the National Green Tribunal in the matter of Vikrant Kumar Tongad Vs. Environment Pollution Authority & Ors. dated 25/09/2014 regarding controlling and preventing the pollution arising from crop burning. The Tribunal has asked the Additional Secretary, Ministry of Agriculture, Additional Secretary, MoEF and the Chairman, Central Pollution Control Board to finalise a national policy and place the copy thereof before the Tribunal.

Recent studies show that current trends in yield improvement will not be sufficient to meet projected global food demand in 2050, and suggest that a further expansion of agricultural area will be required. However, agriculture is the main driver of losses of biodiversity and a major contributor to climate change and pollution, and so further expansion is undesirable. The usual proposed alternative—intensification with increased resource use—also has negative effects.

5921–5941One seventh of the world's population lives in the Indo-Gangetic Plain (IGP) and the fertile region sustains agricultural food crop production for much of South Asia, yet it remains one the most under-studied regions of the world in terms of atmospheric composition and chemistry. In particular, the emissions and chemistry of volatile organic compounds (VOCs) that form surface ozone and secondary organic aerosol through photochemical reactions involving nitrogen oxides are not well understood.

Thousands of volatile organic compounds (VOCs) in the Earth's atmosphere exist which play an important role in various photochemical processes. However, the global model simulations of tropospheric chemistry deal with limited data of speciated VOCs. In the present study, we have used the Global Fire Emissions Database inventory of VOCs emitted from biomass burning in India during the period from 1997 to 2009.

Order of the National Green Tribunal (Principal Bench, New Delhi) in the matter of Vikrant Kumar Tongad Vs. Environment Pollution Authority & Ors. dated 21/03/2014 regarding for preventing, controlling and infact totally prohibiting burning of agricultural residue in the State of Uttar Pradesh and Punjab.

NGT has directed the Ministry of Agriculture to hold a meeting of all the States including State of Punjab and Haryana, CPCB and the National Academy of Agricultural Sciences, New Delhi and prepare composite and complete guidelines for preventing and controlling the pollution resulting from burning agricultural remnants in the open fields.

With limited land resources, inadequate energy supply, and growing water stress, South Asia faces the challenge of providing enough water and energy to grow enough food for the burgeoning population. Using secondary data from diverse sources, this paper explores the food, water, and energy nexus from a regional dimension, emphasizing the role of Hindu Kush Himalayan (HKH) ecosystem services in sustaining food, water, and energy security downstream.

This report is unique in presenting a high-resolution dataset of biomass use, production, feed efficiencies, and greenhouse gas emissions by global livestock. This information will allow the global-change research community in enhancing our understanding of the sustainability of livestock systems and their role in food security, livelihoods and environmental sustainability.
