Natural farming methods help the ‘climate-smart’ villages of MP brave climate impacts

“Adopting techniques like digging ponds in the fields, direct seeding of paddy, cultivation of pulses and soybeans in raised beds and composting instead of stubble burning have enabled farmers to withstand the vagaries of the weather,” Srivastava explained.

Traditional methods of farming such as use of cow dung manure and cow urine are also promoted as useful techniques. Farmers claim that these natural methods of farming not only reduce the cost but also increase the quality of soil and crop.

Farmer Devsharan Patel who does not employ chemical fertilisers said, “In just three years, the nature of soil in my farm has changed. It can now absorb more water, so the crop can be harvested even when the monsoon has been deficient.”

Sangeeta Lenka, a senior scientist at the Indian Institute of Soil Science (IISS), established under the Indian Council of Agricultural Research (ICAR), conducted tests on the soil after the commencement of the project. She backs Patel’s findings and says that the soil quality has improved in the fields of those farmers who have switched to newer methods of farming.

In July 2019, The Soil Institute of India had taken soil samples from the fields of many farmers in 20 villages of Satna. The baseline soil survey and lab results analysed by Lenka showed that the soil previously had low nitrogen and zinc. Also, phosphorus, sulphur, iron, and manganese were found to be deficient in some villages. However, after three years, the results of the soil tests have come positive.

Apart from Satna, soil testing was also done in the villages of Rajgarh and Sehore districts. After analysing the report, Lenka said, “A 34 percent increase in biological activity in the soil was observed in Rajgarh.”

The soil test revealed that the natural methods of cultivation had a positive impact on the surface layer (0-15 cm) of the soil and an increase in enzyme activities was also noticed. Levels of Dehydrogenase (14%) and alkaline phosphatase (18.2%) were found to be high as compared to earlier. Also, the basal soil respiration (24%), which is an indicator of improvement in soil quality, was also observed.

Costs versus profits in climate-smart agriculture

Patel’s family owns a 10-acre land. He decided to first practice natural farming on two acres. He says that in the natural way of farming, it costs him Rs 5,000-7,000 to prepare one acre for wheat, whereas it would cost Rs. 10,000-12,000 when he mixes chemical fertilisers and pesticides. He observes a marked improvement in the quality of crops grown in natural farming methods. “Also, the production has increased by 10 to 20 percent,” he noted.

“Our crops are good in quality. If our yield fetches a high price, then we can make a profit despite low production. But every crop fetches the same price in the market,” Patel added.

When Lenka analysed the production data, she found that there has been an increase in the yield in these districts. The farmers are also happy with an average 30 percent increase in the yield. In some places, the yield has increased by 43 percent.

However, not getting the right market for the produce still remains a problem for the farmers. Devsharan Patel said, “Though there has been an improvement in the quality of the crop, we get the same price for our produce. Currently, no one in the local market is in a position to pay us more for our organic crops.”

Carbon sequestration

Environment Planning and Coordination Organization (EPCO), a Bhopal-based government organisation, played an important role in launching the Climate-Smart Villages project in Madhya Pradesh. Lokendra Thakkar, a senior scientist and EPCO coordinator, told Mongabay-India, “Climate change impacts cities as well as villages. Agriculture plays a major role in the rural economy. The aim of this project is to make agriculture climate-friendly by reducing carbon emissions and changing farming methods.”

In Madhya Pradesh, agriculture contributes 16-17 percent of greenhouse gas emissions, according to the state government data. Through this project, farmers are being aware of this data. According to a report by the INCCA, agriculture and animal husbandry together account for 18 percent of greenhouse gas emissions in India.

Thakkar elaborated, “Under this project, a solution has also been found for stubble burning through crop residue management. Farmers are now using crop residue as manure in the field.” The project also plans to sequester carbon in the soil. Improving the quality of the soil accelerates the rate of absorption of carbon dioxide from the atmosphere.

Lenka, who studied the soil quality improvement, also found from the samples collected, that the fields where farming is being done naturally have more organic carbon in the soil. “Adoption of climate-smart farming practices has shown that there has been an increase in organic carbon and dehydrogenase activity in the soil by an average of 10.7% to 11.55%,” she said.

The test results showed that soil collected from Rajgarh showed the highest organic carbon content of up to 20 percent. A 30 percent increase in yield and a 15.7 percent increase in soil nutrients was also recorded. In Sehore district, an increase of seven percent in the amount of Soil Organic Carbon (SOC) was found in 15 cm of soil.

With estimated annual emissions of about 2.6 gigatonnes per year, after China and the US, India is the third-largest emitter of carbon dioxide in the world. The government of India is committed to reduce carbon emissions by 50% by 2050 and reach net zero by 2070.

Carbon sinks

According to the 2022 NITI Aayog report, 20 percent of India’s total carbon emissions come from agricultural activities. With 97 metric tonnes per annum (mtpa) emissions, Madhya Pradesh ranks fourth in the country in terms of carbon emissions.

By 2030, India, under the National Determined Contribution (NDC) signed under the Paris Agreement, is committed to creating an additional carbon sink equivalent to 2.5 to 3 billion tonnes of carbon through additional forest and tree cover.

Under climate-smart agriculture, the extra carbon that is stored in the soil by changing the way of farming has also become a carbon sink. According to Lenka, it’s important that carbon stays in the soil for a long time. If farmers leave natural farming midway and switch back to chemical farming, carbon will be released from the soil and reach the atmosphere,” she added.

The Climate-Smart Villages project in Madhya Pradesh concluded in 2022. But the farmers opine that the project should be reintroduced. “We had just started reaping benefits of this project when it was discontinued. It should have continued for a few more years,” farmer Devsharan Patel said.

Thakkar, however, said that ‘Climate-Smart Villages’ was a pilot project. He opined that with the learning and success gained from this, a bigger project, that covers the entire state, can be launched.
