Sustainable Agricultural Chemistry and Food Security in Andhra Pradesh and India

Effects of climate change on food security and nutrition in India: A systematic review

Agriculture plays a pivotal role in the Indian economy. Although its contribution to gross domestic product (GDP) is now around one-sixth, it provides employment to 56 % of the Indian workforce. Thus agriculture not only contributes to overall growth of the economy but also reduces poverty by providing livelihoods and food security to the majority of the population in the country and thus it is the most inclusive growth sector of the Indian economy. The global experience of growth and poverty reduction shows that GDP growth originating in agriculture is at least twice as effective in reducing poverty as GDP growth originating outside agriculture (WDR 2008). The 12th Five-Year Plan’s (2012–2017) approach paper also indicates that agricultural development is an important component of a faster, more inclusive sustainable growth approach. This chapter examines the performance, issues and challenges in agriculture and food security in India. It is organised as follows. Section 2 presents the performance in agriculture, while Sect. 3 looks at performance in food security. Section 4 examines issues and future challenges for achieving higher growth in agriculture and enhanced food security in India.

This study was conducted to assess the temporal changes in the status of food security in India. The food security was assessed in terms of its basic pillars—availability access and absorption. Findings reveal that though there has been a remarkable improvement in the status of food security in India, the presence of food insecurity on a large scale erodes the large chunk of sheen from the glory of economic development in India. Several initiatives have been taken to tackle the challenge of food security, and the public distribution system (PDS) has been the most important instrument of ensuring food security in India. It has been observed that its contribution to poverty reduction and food security improvement has been increasing over time.

The Public Distribution System (PDS) of India plays a crucial role in reducing food insecurity by acting as a safety net by distributing essentials at a subsidised rate. While the PDS forms a cornerstone of government food and nutrition policy, India continues to be home to a large population of hungry and malnourished people. This review seeks to explore the functioning and efficiency of the PDS in achieving food and nutritional security in India. A comprehensive and systematic search using the key terms “food insecurity” OR “food security” AND “Public Distribution System” OR “PDS” OR “TPDS” AND “India” identified 23 articles which met the inclusion criteria. This review draws attention to the lack of published literature in areas of PDS and food security in India. The findings of the review emphasise the role of PDS in tackling hunger and malnutrition while highlighting its limited role in improving food security and childhood mortality due to operational inefficiencies. The PDS has the potential to act as a solution to food insecurity in India if the operational inefficiencies and environmental footprints are addressed by adequate policy reforms.

Climate change, famine, and low-income communities challenge Sustainable Development Goals

The present study assesses the effect of climatic and non-climatic factors on sustainable food security in India. It estimates food security index using composite Z-index technique with panel data of 13 states of India. It reveals that all components of food security have positive and significant association to each other. There exists high food inequality across Indian states. Poverty is the most detrimental factor to sustain food security; it is significantly associated with food insecurity. Therefore, Indian policy makers are desired to implement effective development scheme for poverty eradication. Estimates also imply that per capita food-grain availability negatively impacted due to changing climatic factors and diversity in socio-economic variables. Hence, there is essential to increase food production through cropping intensity, appropriate irrigation facilities, application of modern technology and high yielding varieties of seeds in cultivation; infrastructural development and more public spending in agricultural R&D to achieve sustainable food security in India.

This research paper analyzes the impact of climate change on agricultural productivity in quantity terms, value of production in monetary terms and food security in India. The study undertook state wise analysis based on secondary data for the duration of 1980 to 2009. Climate variation affects food grain and non-food grain productivity and both these factors along with other socioeconomic and government policy variables affect food security. Food security and poverty are interlinked with each other as cause and effect and vice versa, particularly, for a largely agrarian economy of India. Regression results for models proposed in this study show that for most of the food grain crops, non-food grain crops in quantity produced per unit of land and in terms of value of production climate variation cause negative impact. The adverse impact of climate change on the value of agricultural production and food grains indicates food security threat to small and marginal farming households. The state wise food security index was also generated in this study; and econometric model estimation reveals that the food security index itself also gets adversely affected due to climatic fluctuations.

The aim of this study was to evaluate the impact of the COVID-19 lockdown on agricultural production, livelihoods, food security, and dietary diversity in India. Phone interview surveys were conducted by trained enumerators across 12 states and 200 districts in India from 3 to 15 May 2020. A total of 1437 farmers completed the survey (94% male; 28% 30–39 years old; 38% with secondary schooling). About one in ten farmers (11%) did not harvest in the past month with primary reasons cited being unfavorable weather (37%) and lockdown-related reasons (24%). A total of 63% of farmers harvested in the past month (primarily wheat and vegetables), but only 44% had sold their crop; 12% were still trying to sell their crop, and 39% had stored their crop, with more than half (55%) reporting lockdown-related issues as the reason for storing. Seventy-nine percent of households with wage-workers witnessed a decline in wages in the past month and 49% of households with incomes from livestock witnessed a decline. Landless farmers were about 10 times more likely to skip a meal as compared to large farmers (18% versus 2%), but a majority reported receiving extra food rations from the government. Nearly all farmers reported consuming staple grains daily in the past week (97%), 63% consumed dairy daily, 40% vegetables daily, 26% pulses daily, and 7% fruit daily. These values are much lower than reported previously for farmers in India around this time of year before COVID-19: 94–95% dairy daily, 57–58% pulses daily, 64–65% vegetables daily, and 42–43% fruit daily. In conclusion, we found that the COVID-19 lockdown in India has primarily impacted farmers’ ability to sell their crops and livestock products and decreased daily wages and dietary diversity.

Controversy exists over whether to target public- and private-sector programs to female-headed households in developing countries in the attempt to combat poverty and social disadvantage. The issues related to the definition and measurement of female headship and the importance of the concept for development policy are discussed. A systematic review is then presented of the empirical evidence on the relation between female headship and poverty. If female-headed households tend to be poorer on average than other households headship should seriously be considered as a potentially useful criterion for targeting antipoverty interventions especially in developing countries where means testing is not feasible. The authors examine the potential costs and benefits of targeting female headship and review the experience of Chile one of the few countries which has targeted female headship through government intervention and the only one which has evaluation data available. The analysis of the project experience is used along with a review of the empirical evidence to answer the question of the desirability and efficiency of targeting female headship in order to reduce poverty in developing countries.

Agriculture production is directly dependent on climate change and weather. Possible changes in temperature, precipitation and CO2 concentration are expected to significantly impact crop growth and ultimately we lose our crop productivity and indirectly affect the sustainable food availability issue. The overall impact of climate change on worldwide food production is considered to be low to moderate with successful adaptation and adequate irrigation. Climate change has a serious impact on the availability of various resources on the earth especially water, which sustains life on this planet. The global food security situation and outlook remains delicately imbalanced amid surplus food production and the prevalence of hunger, due to the complex interplay of social, economic, and ecological factors that mediate food security outcomes at various human and institutional scales. Weather aberration poses complex challenges in terms of increased variability and risk for food producers and the energy and water sectors. Changes in the biosphere, biodiversity and natural resources are adversely affecting human health and quality of life. Throughout the 21st century, India is projected to experience warming above global level. India will also begin to experience more seasonal variation in temperature with more warming in the winters than summers. Longevity of heat waves across India has extended in recent years with warmer night temperatures and hotter days, and this trend is expected to continue. Strategic research priorities are outlined for a range of sectors that underpin global food security, including: agriculture, ecosystem services from agriculture, climate change, international trade, water management solutions, the water-energy-food security nexus, service delivery to smallholders and women farmers, and better governance models and regional priority setting. There is a need to look beyond agriculture and invest in affordable and suitable farm technologies if the problem of food insecurity is to be addressed in a sustainable manner. Introduction Globally, agriculture is one of the most vulnerable sectors to climate change. This vulnerability is relatively higher in India in view of the large population depending on agriculture and poor coping capabilities of small and marginal farmers. Impacts of climate change pose a serious threat to food security. “Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life” (World Food Summit, 1996). This definition gives rise to four dimensions of food security: availability of food, accessibility (economically and physically), utilization (the way it is used and assimilated by the human body) and stability of these three dimensions. According to the United Nations, in 2015, there are still 836 million people in the world living in extreme poverty (less than USD1.25/day) (UN, 2015). And according to the International Fund for Agricultural Development (IFAD), at least 70 percent of the very poor live in rural areas, most of them depending partly (or completely) on agriculture for their livelihoods. It is estimated that 500 million smallholder farms in the developing world are supporting almost 2 billion people, and in Asia and sub-Saharan Africa these small farms produce about 80 percent of the food consumed. Climate change threatens to reverse the progress made so far in the fight against hunger and malnutrition. As highlighted by the assessment report of the Intergovernmental Panel on Climate change (IPCC), climate change augments and intensifies risks to food security for the most vulnerable countries and populations. Few of the major risks induced by climate change, as identified by IPCC have direct consequences for food security (IPCC, 2007). These are mainly to loss of rural livelihoods and income, loss of marine and coastal ecosystems, livelihoods loss of terrestrial and inland water ecosystems and food insecurity (breakdown of food systems). Rural farmers, whose livelihood depends on the use of natural resources, are likely to bear the brunt of adverse impacts. Most of the crop simulation model runs and experiments under elevated temperature and carbon dioxide indicate that by 2030, a 3-7% decline in the yield of principal cereal crops like rice and wheat is likely in India by adoption of current production technologies. Global warming impacts growth, reproduction and yields of food and horticulture crops, increases crop water requirement, causes more soil erosion, increases thermal stress on animals leading to decreased milk yields and change the distribution and breeding season of fisheries. Fast changing climatic conditions, shrinking land, water and other natural resources with rapid growing population around the globe has put many challenges before us (Mukherjee, 2014). Food is going to be second most challenging issue for mankind in time to come. India will also begin to experience more seasonal variation in temperature with more warming in the winters than summers (Christensen et al., 2007). Climate change is posing a great threat to agriculture and food security in India and it's subcontinent. Water is the most critical agricultural input in India, as 55% of the total cultivated areas do not have irrigation facilities. Currently we are able to secure food supplies under these varying conditions. Under the threat of climate variability, our food grain production system becomes quite comfortable and easily accessible for local people. India's food grain production is estimated to rise 2 per cent in 2020-21 crop years to an all-time high of 303.34 million tonnes on better output of rice, wheat, pulse and coarse cereals amid good monsoon rains last year. In the 2019-20 crop year, the country's food grain output (comprising wheat, rice, pulses and coarse cereals) stood at a record 297.5 million tonnes (MT). Releasing the second advance estimates for 2020-21 crop year, the agriculture ministry said foodgrain production is projected at a record 303.34 MT. As per the data, rice production is pegged at record 120.32 MT as against 118.87 MT in the previous year. Wheat production is estimated to rise to a record 109.24 MT in 2020-21 from 107.86 MT in the previous year, while output of coarse cereals is likely to increase to 49.36 MT from 47.75 MT. Pulses output is seen at 24.42 MT, up from 23.03 MT in 2019-20 crop year. In the non-foodgrain category, the production of oilseeds is estimated at 37.31 MT in 2020-21 as against 33.22 MT in the previous year. Sugarcane production is pegged at 397.66 MT from 370.50 MT in the previous year, while cotton output is expected to be higher at 36.54 million bales (170 kg each) from 36.07. This production figure seem to be sufficient for current population, but we need to improve more and more with vertical farming and advance agronomic and crop improvement tools for future burgeoning population figure under the milieu of climate change issue. Our rural mass and tribal people have very limited resources and they sometime complete depend on forest microhabitat. To order to ensure food and nutritional security for growing population, a new strategy needs to be initiated for growing of crops in changing climatic condition. The country has a large pool of underutilized or underexploited fruit or cereals crops which have enormous potential for contributing to food security, nutrition, health, ecosystem sustainability under the changing climatic conditions, since they require little input, as they have inherent capabilities to withstand biotic and abiotic stress. Apart from the impacts on agronomic conditions of crop productions, climate change also affects the economy, food systems and wellbeing of the consumers (Abbade, 2017). Crop nutritional quality become very challenging, as we noticed that, zinc and iron deficiency is a serious global health problem in humans depending on cereal-diet and is largely prevalent in low-income countries like Sub-Saharan Africa, and South and South-east Asia. We report inefficiency of modern-bred cultivars of rice and wheat to sequester those essential nutrients in grains as the reason for such deficiency and prevalence (Debnath et al., 2021). Keeping in mind the crop yield and nutritional quality become very daunting task to our food security issue and this can overcome with the proper and time bound research in cognizance with the environment. Threat and challenges In recent years, climate change has become a debatable issue worldwide. South Asia will be one of the most adversely affected regions in terms of impacts of climate change on agricultural yield, economic activity and trading policies. Addressing climate change is central for global future food security and poverty alleviation. The approach would need to implement strategies linked with developmental plans to enhance its adaptive capacity in terms of climate resilience and mitigation. Over time, there has been a visible shift in the global climate change initiative towards adaptation. Adaptation can complement mitigation as a cost-effective strategy to reduce climate change risks. The impact of climate change is projected to have different effects across societies and countries. Mitigation and adaptation actions can, if appropriately designed, advance sustainable development and equity both within and across countries and between generations. One approach to balancing the attention on adaptation and mitigation strategies is to compare the costs and benefits of both the strategies. The most imminent change is the increase in the atmospheric temperatures due to increase levels of GHGs (Green House Gases) i.e. carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and chlorofluorocarbons (CFCs) etc into the atmosphere.

India’s transition from a food-deficit to a food-surplus nation represents one of the most significant achievements in its developmental history. However, this success is undermined by the persistent gap between rising foodgrain production and inadequate storage capacity, which continues to limit the effectiveness of food security measures. While production has surpassed 350 million tonnes in recent years, government-supported storage infrastructure accounts for barely one-third of this output, leading to post-harvest losses, quality deterioration, and inefficiencies in the Public Distribution System (PDS). These challenges highlight the importance of viewing storage as a critical component of the food security chain, alongside production and distribution. This paper critically examines the role of foodgrain storage schemes in bridging the production–consumption gap. Using secondary data from government sources, research reports, and policy documents (2015–2025), the study analyzes trends in production, storage capacity, procurement, and post-harvest losses. It reviews key initiatives such as the Private Entrepreneur Guarantee (PEG) Scheme, modernization of steel silos, the Agriculture Infrastructure Fund (AIF), and the Decentralized Procurement Scheme (DCP), while also evaluating their impact on supply chain efficiency and food security outcomes. The analysis reveals that although substantial progress has been made in expanding storage infrastructure and introducing scientific practices, significant gaps remain due to uneven regional coverage, inadequate rural-level storage, and slow adoption of modern technologies. The paper argues that sustainable food security in India cannot be achieved through production growth alone, but requires integrated storage solutions that are scientific, inclusive, and climate-resilient. Policy recommendations include accelerating silo-based modernization, scaling up decentralized and farmer-level storage, integrating digital technologies into stock monitoring, and fostering stronger public–private partnerships. By aligning production gains with robust storage systems, India can minimize post-harvest losses, stabilize supply chains, and ensure equitable food access to its population.

While the world is grappling with adversities caused by climate change, the agricultural sector has been the hardest hit, posing a new set of challenges for food security. As the developing world is still struggling with rampant poverty and malnutrition, an alternative framework that could promote climate-resilient and water-saving agriculture emerges as an exigency. In this context, climate-resilient crops like millets acquire the greatest significance as they are not only sustainable and low on climate-critical resources like water but also add to the diversity of the nutritional basket of farmers in rain-fed regions. In this light, the adoption of the India-sponsored resolution declaring 2023 as the International Year of Millets by the United Nations General Assembly is extremely crucial and needs to be analysed with reference to its potentiality to ensure sustainable food security in India in sync with UN Sustainable Development Goals on Poverty and Food Security. Given the potential of millets, this article aims to analyse innovative and sustainable pathways to agriculture from Indian Independence to Amrit Kaal, in alignment with goals of productivity enhancement, energy transition and climate action of the Government of India. It examines the policies and programmes of the government implemented to achieve the goal of Viksit Bharat (Developed India) during the Amrit Kaal.

Nanotechnology for enhancing food security in India

One of the prime concerns of India’s policies has been the food and nutritional security to its population. The three important components of food security are: availability, access, and absorption (nutrition). These three are interrelated. The major aim of this paper is to examine the performance in food security in India in respect of these three components. In respect of availability, The average annual growth rates in Yields of Food grain Production and in Area under cultivation for Food grain Production have been computed for five time periods; pre green revolution 1950-51 to 66-67), early green revolution (1967-68 to 1979-80), mature green revolution (1980-81 to 1989-90), early economic reforms (1990-91 to 1999-00), and economic reforms (2000-01 to 2011-12). The food grains production has deteriorated when India entered in the era of globalization. The free market play has adversely affected the production of food grains and the rate of growth of food grains production declined after the introduction of New Economic Policy (NEP) in India. So far as the accessibility aspect of food security is concerned, long term trend in consumption pattern at household level shows that per capita direct consumption of food grains has been declining. Further India’s performance in food security on nutritional outcomes has not been very satisfactory. The Global Food Security Index 2012 released in New Delhi in September, 2012, placed India in a moderate category. It ranked India 66th among 105 nations and cited affordability rather than availability as a key food security threat for Indians. India scored highest in food availability (51.3) but lowest (38.4) in terms of food access. It also points to its poor ability to move food efficiently because of infrastructure problems. Similarly, in food security index 2013, India slipped to 70 position. We live in paradoxical times, and it is not the shortage of food but the lack of a proper food distribution network that is to blame.

This chapter highlights the threat that climate change poses for India’s food security and the nutritional challenges faced by large sections of India’s population. Strains on the cultivation of key crops and rapid population growth render India extremely vulnerable to the impacts of climate change. The present chapter discusses the impacts of climate change on four aspects of food security in India – food availability, access, utilization, and stability. The chapter argues that India needs to comprehensively address the challenges that climate change poses to its food security.
