What is regenerative agriculture? Is it the answer to stubble burning?

With no respite from the extremely toxic air, significant areas of Delhi are struggling to breathe. The National Capital Region (NCR) and the surrounding states of Punjab, Haryana, Uttar Pradesh, and Rajasthan must put an end to stubble burning to solve this problem. In light of this, businessman Anand Mahindra has emphasised the significance of “regenerative agriculture.” “To heal Delhi’s pollution, Regenerative Agriculture MUST be given a chance. It provides a remunerative alternative to stubble burning while simultaneously increasing soil productivity. Vikash Abraham of Naandi Foundation stands ready to help. Let’s do it!” he urged on X (formerly Twitter).

Founded in 1998 as a public charitable trust, the Naandi Foundation manages thousands of centres for girls’ education and skill development as well as job opportunities. Mahindra chairs the board of the Foundation. What is regenerative agriculture? The World Economic Forum (WEF) explains regenerative agriculture or regenerative farming focuses on “the health of the soil, which has been degraded by the use of heavy machinery, fertilisers, and pesticides in intensive farming.” It is primarily an outcome-based approach designed to improve soil health, mitigate agriculture’s negative effects on the environment, water resources, and biodiversity, and increase farm production and profitability. Its methods include limiting land ploughing, which maintains carbon dioxide levels in the soil, enhancing its water-absorbing capacity, and preserving the integrity of the earth’s essential fungal ecosystems. Utilising compost and animal dung helps replenish the soil’s nutrients, and rotating crops enhances biodiversity by allowing for a diversity of crop plantings, according to Hindustan Times. It is practised in Asia, Latin America, the US, Canada, Africa, Europe, Australia, and New Zealand. To grow commercial commodities like cardamom alongside maize, beans, and bananas, farmers in Tanzania and East Africa also employ regenerative farming. Global leaders and multinational companies are also eager to implement this sustainable agriculture technique in order to strengthen the food chain and lessen the effects on the already failing ecology, as the challenges posed by climate change are drawing near.

Paddy crop residues are removed from fields by farmers in the agrarian regions of Punjab, Haryana, Rajasthan, and Uttar Pradesh in order to plant the following crop between mid-September and November. In addition to vehicle emissions, this technique known as stubble burning is a major factor in the declining AQI in the National Capital. According to a Moneycontrol report, the farmers have mostly adopted this practise because of the limited window of time between harvesting rice and sowing wheat. But this extremely unsustainable approach degrades soil fertility and pollutes the air. On the other hand, farmers practising regenerative agriculture continue to rotate between cash and cover crops by planting a new crop right away after harvest. Rotating crops at regular intervals preserves soil moisture content and aids in the management of pest infestations, the report explains. Additionally, it offers a varied diet to support the beneficial microorganisms in the soil. Crop rotation between nitrogen-fixing and nitrogen-hungry crops also helps farmers use less fertilisers, which is another important farming input that pollutes the soil and water. Relay planting is another key method in regenerative farming, whereby the seeds of the subsequent crop are sown while the current harvest is still in the reproductive stage. Here, farmers can decrease the likelihood of stubble burning by using relay planting to mitigate the risk of missing crop sowing deadlines. What are its other benefits? Regenerative agriculture can help to tackle the looming food crisis in many developing or underdeveloped countries has been the major repercussion of the climate change. The sustainable practice can also help multinational companies to achieve their net-zero goals. Global giants – Apple, Unilever, PepsiCo, Microsoft among others are focusing on developing a sustainable value chain system and organically growing their operations. How is soil health linked to pollution? The United Nations (UN) estimates that agriculture accounts for one-third of greenhouse gas emissions globally, with degraded soil contributing to the environment’s vulnerability.

Reuters[/caption] According to Livemint, environments can become more susceptible to extreme weather events like flooding due to damaged soil and eroded terrain. The natural storage of carbon dioxide in the soil is disturbed by intensive farming practises, the use of pesticides, fertilisers, and heavy machinery to increase food production, which also degrades the soil. A healthy soil, on the other hand, enhances biodiversity, or the range of species, generates more food and nutrition, and stores more carbon. The outlet quoted farming charity Regeneration International as warning that there might not be enough soil left to produce enough food to feed everyone in the next 50 years. According to a WEF 2022 article, “more than half of the world’s agricultural land is degraded. This leads to productivity losses of $400 billion a year and is a risk to food security in the future. Regenerative farming can restore agricultural land and reduce the industry’s environmental impact, including lowering greenhouse gas emissions.” How bad is Delhi’s pollution? Following a little improvement to the “very poor” category, the national capital’s air quality index (AQI) returned to “severe” category on Thursday morning. At 8 am, the AQI reported in Anand Vihar was 429, 445 in IGI Airport, 433 in Jahangirpuri, 431 in Ashok Vihar, 462 in Dwarka Sector 8, 443 in ITO, according to the Central Pollution Control Board (CPCB).
