India’s agricultural sector is highly vulnerable to the effects of climate change and extreme weather events. Since the mid-1950s, India has experienced a rise in average temperatures, a decrease in monsoon precipitation, increased frequencies of extreme temperature, rainfall and drought events, an increase in the intensity of severe cyclones, and other changes in the monsoon system (Ministry of Earth Sciences, 2020[6]).
Environmental sustainability and resilience measures in agriculture – and climate-change adaptation measures in particular – have been gaining prominence, notably through programmes called “missions”. India’s 2008 National Action Plan on Climate Change (NAPCC) included four missions focused on adaptation efforts: (1) sustainable habitats; (2) optimising water-use efficiency; (3) creating ecologically-sustainable climate-resilient agricultural production systems; and (4) safeguarding the Himalayan glaciers and mountain ecosystems. These missions include initiatives related to water usage, disaster management, biodiversity conservation, and ecosystem protection. In addition, India implements specific schemes that promote organic farming, efficient irrigation systems, watershed management, and improved soil health and climate-resilient agro-ecological systems.
The National Mission for Sustainable Agriculture (NMSA) within the NAPCC became operational in 2014‑15, promoting soil and moisture conservation measures; comprehensive soil health management; efficient water management practices, and mainstreaming rain-fed technologies. “Farm Water Management” was implemented as one of the components of NMSA with the objective of enhancing water use efficiency by promoting technological interventions such as drip and sprinkler technologies, efficient water application and distribution systems, and secondary storage. Thereafter, these activities have been subsumed under the “Per Drop More Crop (PDMC)” component of the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) scheme in 2015-16. This scheme prioritises water conservation and its management in agriculture with the objective to extend the area under irrigation while preserving water resources.
Also under the NMSA, “Rainfed Area Development” focuses on Integrated Farming Systems to enhance productivity and minimise risks associated with climatic variability. Under this system, crops and cropping systems are integrated with other activities such as horticulture, livestock, fisheries, agro-forestry, and beekeeping to support farmers by providing additional income opportunities and mitigate the impacts of droughts, floods, or other extreme weather events. The Mission for Integrated Development of Horticulture (MIDH) includes a sub-component focused on “Creation of water resources”, while the National Food Security Mission (NFSM) includes components such as “Water Carrying Pipes” and “Mobile Rain Gun” focused on hydrological infrastructure and water-use efficiency.
“Soil Health Management” is another component under the NMSA. It promotes integrated nutrient management through targeted use of mineral fertilisers, including secondary and micro-nutrients, in conjunction with organic manures and bio-fertilisers to improve soil health and productivity. It also improves soil and fertiliser testing facilities, providing soil test-based recommendations to farmers for improving fertility. The Soil Health Card implemented in 2015 provides information to farmers about the nutrient status of their soil and recommends the appropriate dosage of nutrients to improve its health and fertility.
India is implementing specific schemes to promote organic farming, including the Organic Value Chain Development for North-East Region and the MIDH component “Adoption of Organic Farming” (in addition to the above-noted Paramparagat Krishi Vikas Yojana Mission). Missions such as the National Mission on Agricultural Extension and Technology aim to improve soil health and climate-resilient agro-ecological systems through technical assistance.
The GoI has been covering part of the premium for crop insurance through crop insurance schemes since 2000. These include the National Agricultural Insurance Scheme, the Modified National Agricultural Insurance Scheme, the Weather Based Crop Insurance Scheme, the Coconut Palm Insurance Scheme, the National Crop Insurance Program, the Restructured Weather Based Crop Insurance Scheme, and most recently, the Pradhan Mantri Fasal Bima Yojna (PMFBY) scheme. PMFBY, introduced in 2016, provides insurance to farmers for crop losses due to monsoon fluctuations or other extreme weather events.
Public-sector research focuses on developing new crop varieties and management practices to improve yields and tackle pests/diseases for various agro-climatic conditions. The Indian Council of Agricultural Research (ICAR) launched the National Innovations in Climate Resilient Agriculture (NICRA) project in 2011 to enhance the resilience of Indian agriculture to climatic variability and climate change through strategic research and technology demonstration in crops, livestock, and fisheries. The project focuses on selected commodities, such as wheat, rice, maize, pigeon pea, groundnut, tomato, mango, banana, cattle, buffalo, and small ruminants. Major research themes include assessing the vulnerability of major production zones; assessing the impacts of and developing varieties tolerant to climatic stresses (e.g. drought, heat, flooding) in grain and horticulture crops; evolving adaptation and mitigation strategies through enhanced water- and nutrient-use efficiency and conservation agriculture; studying changes in pest dynamics, pest- and pathogen-crop relationships, and emergence of new pests and pathogens under climate change. The emphasis on new varieties and new technologies translates into programmes such as Crop Science, Horticulture Science, and Plant Science. The MIDH also includes the “Promotion of Integrated Pest Management” programme. The Livestock Health and Disease Control Programme focuses on disease control in the livestock sector and was launched in 2021.
Ongoing agro-climatic research includes the development of drought- and heat-tolerant genotypes in chickpea, pigeon pea, and mung bean and the development of drought-tolerant onions and other horticultural crops. India’s research institutions have also developed flood- and drought-tolerant rice varieties and early-maturing wheat varieties for late-sowing areas to avoid terminal heat stress at the time of maturity. The National Agricultural Research System (NARS) is developing location-specific wheat varieties with traits addressing crop duration, varied soil conditions, and improved grain qualities while increasing grain yield levels through traditional breeding.
ICAR and various state agricultural universities (SAU) are targeting research to develop response mechanisms through early planting and short-duration varieties to mitigate potential climate-change risks. The NFSM includes components focused on capacity building, namely “Cropping-system-based training” and “Demonstrations on improved package for rice”, while the MIDH includes “Technology dissemination through demonstration” and “Good Agriculture Practices”. Several programmes focus on improving production practices, such as the “National Innovations in Climate Resilient Agriculture” (NICRA), “Drought and heat tolerant genotypes”, or “Agronomic management - Early planting”.
The GoI introduced new extension services for rice farmers in May 2022. These focus on disseminating agricultural production practices that help producers use less water and chemical fertilisers. In July 2022, the GoI also introduced extension and advisory services for farmers about mitigating extreme weather conditions and adverse impacts on agricultural production, using climate-resilient seed varieties, including rice and maize. This includes providing local weather information, including alerts and related agro-meteorological advisories using e-services launched by the Ministry of Earth Sciences. India first set up its National Monsoon Mission to improve weather forecasts for farmers in 2012.
India’s 2022 updated NDC focuses on adapting to climate change by enhancing investments in development programmes for sectors vulnerable to climate change, particularly agriculture, water resources, the Himalayan region, coastal regions, and health and disaster management.
