5 facts for one-day exams
SSC, railway, police and teaching exams ask direct questions like these.
- Climate change may cut rainfed rice and wheat yields by up to 20% by 2050.
- Scientists recommend soil restoration agriculture, rainwater harvesting, and groundwater recharge.
- IIT Kanpur hosted a summit on soil and ecological restoration-based agriculture.
- The initiatives have reached over 8,000 farmers across 5,000 acres.
- About 1.3 crore litres of groundwater has been saved through these initiatives.
Why in the news?
Scientists have warned that climate change could reduce rainfed rice and wheat yields by up to 20% by 2050. They recommend soil and ecological restoration-based farming, rainwater harvesting, groundwater recharge, and sustainable agricultural practices to mitigate the impact. A report based on their research will be submitted to the government.
Summary
- Climate change projected to cut rainfed rice and wheat yields by 20% by 2050.
- Recommended solutions include soil and ecological restoration-based agriculture, water conservation, and sustainable farming practices.
- IIT Kanpur hosted a summit on 'Soil and Ecological Restoration-based Agriculture, Water and Energy for Mitigating Climate Change Impacts'.
Highlights
Crop Yield Threat
Climate change may reduce rainfed rice and wheat yields by up to 20% by 2050.
Soil Restoration Focus
Scientists advocate for soil and ecological restoration-based farming as a key solution.
Water Conservation Push
Rainwater harvesting and groundwater recharge are recommended to combat climate impacts.
Background
Rainfed agriculture, which relies on monsoon rainfall, is highly vulnerable to climate change. India has a large area under rainfed farming, and rice and wheat are major staple crops. A 20% yield reduction by 2050 would threaten food security and farmer livelihoods, especially in states such as Bihar, Uttar Pradesh and Madhya Pradesh.
Key Analysis and Impact
The warning comes from scientists including those from IIT Kanpur. They emphasize that soil and ecological restoration-based agriculture can improve soil quality and water retention. Their initiatives have already reached over 8,000 farmers across 5,000 acres, saving about 1.3 crore litres of groundwater. This shows practical, scalable solutions exist but need policy backing.
Way Forward
A comprehensive report based on scientific research and innovations will be submitted to the government. Experts call for coordinated efforts integrating science, technology, and policy, and for implementing special plans to bring scientific knowledge to farms. Prioritizing regenerative agriculture, sustainable water management, and clean energy in rural areas is essential.
Background GK
Textbook concepts you need to understand this news
- Rainfed Agriculture
- Farming that depends entirely on rainfall for water, without irrigation. It is common in regions with adequate monsoon rainfall and supports crops like rice, millets, and pulses.
- Soil and Ecological Restoration
- Practices that rebuild soil health and ecosystem functions, such as using organic matter, cover crops, and reduced tillage, to enhance water retention and carbon storage.
- Groundwater Recharge
- The process of replenishing underground aquifers through natural or artificial means like rainwater harvesting, percolation tanks, and check dams.

How exams will ask this
- Data: Up to 20% yield reduction in rainfed rice and wheat by 2050
- Nodal Body: Ministry of Environment, Forest and Climate Change / Ministry of Agriculture and Farmers Welfare
Don't make this mistake!
The 20% reduction applies specifically to rainfed rice and wheat, not all rice and wheat. Also, it is a projection by 2050, not an immediate or current decline. Do not confuse with total agricultural GDP or irrigated crop yields.

Stuck? Get it in one tap
Scientists from IIT Kanpur and other institutions have warned that climate change could reduce the amount of rice and wheat grown without irrigation by up to 20% by the year 2050. To prevent this, they suggest improving soil health, collecting rainwater, and using farming methods that protect the environment. These practices have already helped save a large amount of groundwater and benefited thousands of farmers.

Practice questions
Pick an answer, then read the explanation.
- Q1Easy
Which type of agriculture is most vulnerable to the climate change impacts mentioned in the news?
Explanation: The news specifically warns about yield reductions in rainfed rice and wheat, meaning crops that depend entirely on rainfall. Irrigated agriculture is less vulnerable to rainfall variability. Organic and hydroponic agriculture are not the focus of this warning.
- Q2Hard
Consider the following statements:
- 1.Climate change may reduce rainfed rice and wheat yields by up to 20% by 2050.
- 2.The scientists recommended increasing the use of chemical fertilizers to boost yields.
- 3.A report based on scientific research will be submitted to the government.
Which of the statements given above is/are correct?
Explanation: Statement 1 is correct as per the news. Statement 2 is incorrect because the scientists recommended soil restoration, rainwater harvesting, and sustainable practices, not chemical fertilizers. Statement 3 is correct as the report will be submitted to the government. Hence option C is correct.
- Q3Medium
By which year could rainfed rice and wheat yields decline by up to 20%?
Explanation: The scientists warned that yields could decline by 2050. 2060 is later and not part of the projection.
- Q4Medium
What is the primary objective of the soil and ecological restoration-based agriculture recommended in the news?
Explanation: Soil quality improvement is necessary and that restoration-based practices, along with water conservation, can help mitigate climate impacts. GM seeds, mechanization, and reducing rainfed area are not the focus of the recommendation.
Frequently asked questions
1. How much could rainfed rice and wheat yields decline by 2050 due to climate change?

2. What solutions are recommended to address this yield decline?
Recommended solutions include soil and ecological restoration-based farming, rainwater harvesting, groundwater recharge, and sustainable agricultural practices.
3. Which institute hosted the summit where these warnings were discussed?
IIT Kanpur hosted the Regional Rural-India Summit on the theme of soil and ecological restoration-based agriculture, water and energy.
