Recycling of Rice Straw Helps Control C02 Emissions in North Western India

The biomass management project of Confederation of Indian Industry (CII) implemented in North Western states helped recycle 25000 tonnes of rice straw back into soil and prevented the release of 115 tons of fine particulate matter (PM2.5) into the air. The usual practice is to burn the rice straw and that causes the release of smoke and dust in the atmosphere. 
The report of CII’s Crop Residue Management project of 2017-18 under ‘Cleaner Air, Better Life’ for biomass management in North Western states was released recently.
As per the report, the project led to avoidance of environmental impacts on local, regional and global scales and also led to nutrient savings worth more than INR 1 crore. It improved the farmer’s resilience to adverse impacts of climate change due to water conservation, improved farm biodiversity, and resilience of crops to extreme climatic events.
About 30 kilo tonne CO2e of GHG and 13 tonne BC which would have otherwise been released into the atmosphere are estimated to be fed back into the soil, a portion of which will be sequestered into the soil for hundreds of years. Also, the project led to avoidance of estimated, 140 tonne volatile organic compounds, 82 tonne ammonia, 39 tonne oxides of nitrogen and 6 tonne oxides of sulphur, which could have impacted the ambient air quality across Indo-Gangetic Plains.
Agricultural burning in North Western States (Punjab, Haryana and Delhi) costs the Indian economy a whopping USD 30 million every year due to health impact. It exacerbates climate change as emitted Black Carbon (BC) is considered the second most potent global warming agent after CO2. Burning also adversely impacts farm level biodiversity and leads to over consumption of irrigation water and diesel for farm operations. 
CII worked with the Ministry of Environment Forest & Climate Change to design a plan of action for biomass management (CII-NITI, 2018) in North Western States. A subsidy scheme was launched by the Central Government to support North Western States in their efforts to curb crop residue burning. CII galvanised the industry action on Crop Residue Management (CRM) in 2018 which led to adoption 19 villages in Punjab.
CII Foundation, along with local partners in Punjab, engaged with farmer community to demonstrate solutions in a highly participatory manner. These villages were made free of burning in 2018 by using behaviour change communication and farmers were provided technical handholding for adopting sustainable agricultural practices. This impact report on CRM project is prepared by CII’s Centre of Excellence for Sustainable Development (CESD) under its ‘Cleaner Air Better Life’ strategy for diverse stakeholders to design strategies for improving air quality in India.
Going forward, there is a need to communicate the true cost of burning to farmers, strengthen farmers capacity for planning and undertaking sustainable agricultural practices, and address local factors which hinder in-field management of rice straw. Also, the biomass management ecosystem needs to be strengthened with workable models of ex-situ solutions. CII’s project for ‘Cleaner Air Better Life’ continues to work on this issue.
