In News
- Recently the International Crops Research Institute for The Semi-Arid Tropics (ICRISAT) has published a modelling study.
More about the news
- About the study:
- The study revealed how the right combination of fertilizer, biochar, and irrigation could potentially increase soil carbon by as much as 300 percent and help mitigate climate change.
- The modelling study found that biochar increased carbon value in the soil by 130-300 percent over 30 years with little difference in yield.
- It also found that the optimal use of fertilizers increased the carbon and output by up to 30 percent.
- The study revealed how the right combination of fertilizer, biochar, and irrigation could potentially increase soil carbon by as much as 300 percent and help mitigate climate change.
- Regions under the study:
- The modelling study was conducted in five districts of Maharashtra (Jalna, Dhule, Ahmednagar, Amravati, and Yavatmal) and eight districts of Odisha (Angul, Bolangir, Deogarh, Dhenkenal, Kalahandi, Kendujhar, Nuapada, and Sundegarh).
- They have a predominantly semi-arid climate with annual rainfall between 600 millimetres and 1,100 mm.
- The modelling study was conducted in five districts of Maharashtra (Jalna, Dhule, Ahmednagar, Amravati, and Yavatmal) and eight districts of Odisha (Angul, Bolangir, Deogarh, Dhenkenal, Kalahandi, Kendujhar, Nuapada, and Sundegarh).
- Crops under the study:
- Important crops such as cotton, sorghum, soybean, chickpea, pigeon pea and millet were studied in the region.
- Study of traditional & modern practices:
- In addition, soil sampling and analysis of long-term experiments on improved versus traditional farmer practices and tillage and residue management practices were also conducted.
- The researchers also evaluated improved management practices such as biochar, need-based fertiliser, and irrigation.
Significance
- Contribution of agriculture in the fight against climate crisis:
- Food systems account for nearly one-third of greenhouse gas (GHG) emissions.
- In 2015, food-system emissions amounted to 18 Gt CO2 equivalent per year globally, representing 34 percent of total GHG emissions.
- An agriculture modelling study can help bolster the fight against climate crisis by helping capture atmospheric carbon dioxide and storing it in soil.
- So, Agriculture is said to be one of the major factors affecting climate change. However, it can also be a part of the solution.
- Food systems account for nearly one-third of greenhouse gas (GHG) emissions.
- Contribution of sample study:
- This soil carbon sequestration over 30 years in the sample 13 districts of Maharashtra & Odisha may significantly contribute to combating global climate change.
- Income to farmers:
- Carbon sequestering can provide an additional source of income for the farmers.
- Aligned with SDGs:
- The study is aligned with Sustainable Development Goal 13 (SDG 13: Climate Action) which is on taking urgent action to combat climate change and its impacts.
- Model for the policymakers:
- The study may help policymakers, government, and civil society to implement strategies that incentivise farmers to manage their soils in ways to sequester more carbon.

Other Government efforts
- The Energy Conservation (Amendment) Bill:
- Apart from the other stated objectives, the bill aims to establish Carbon Markets in India.
- The Bill empowers the central government to specify a carbon credit trading scheme.
- The proposed amendments aims to encourage the development of a carbon market by laying the framework for issuance of carbon credits against deployment of clean technology.
- Investment in clean technology will help corporations in greening their business profiles and the attached carbon credits will provide an additional revenue stream.
- Hence, the proposed amendments seek to address a prominent gap in the climate change narrative with respect to involvement of the private sector.
- Apart from the other stated objectives, the bill aims to establish Carbon Markets in India.
- Panchamrit strategy:
- Hon. PM Narendra Modi’s Panchamrit strategy was announced at the COP 26 in Glasgow conference into enhanced climate targets.
- India will increase its non-fossil fuel energy capacity to 500 gigawatt (GW) by 2030.
- It will meet 50 percent of its energy requirements from renewable sources by 2030.
- The total projected carbon emissions will be reduced by 1 billion tonnes from now through 2030.
- The carbon intensity of its economy will be brought down to less than 45 percent.
- India will achieve its target of net zero by 2070.
- India also recently updated its Nationally Determined Contribution (NDC) on the lines of this strategy.
- Hon. PM Narendra Modi’s Panchamrit strategy was announced at the COP 26 in Glasgow conference into enhanced climate targets.
