      Agriculture is not only a key driver for inclusive growth of the economy in Asian countries but also has become means to elevate poverty, employment generation, and food security to the millions of growers, consumers, and other stakeholders in the continent. In addition, the forward and backward linkage effects of agriculture growth have also scaled up the incomes in the nonagriculture enterprises. Within the agricultural sector, smallholder farmers remain central to agricultural development and continue to play important roles for promoting an ecologically rational and socially available food system.

      The primary aim of this book on “Sustainable Agriculture Systems and Technologies” is to advance the scientific understanding and application of technologies addressing a variety of areas related to food security within the context of sustainable productivity, system diversification, irrigation practices, precision agriculture, climate change, crop modeling, big data analytics, farmer's livelihood, and agricultural policy framework in the twenty‐first century. This book will serve as a hand book encompassing several scopes of interests on sustainable agricultural technologies toward improved livelihoods, income generation and addressing sustainable development goals through agriculture, livestock, and fishery resources. A variety of scholars will also be benefited to explore risks and potential solutions in different agricultural systems under changing climate scenario, which can further be transmitted to the producers, policy makers, and other stakeholders. Further, this book will extend knowledge support for academics, researchers, and environmental consultant working within the framework of agricultural sciences.

      I compliment the contributors and the editors for this worthy publication.

1.1 Introduction

India is a young nation with the advantage of demographic dividend. Demographic dividend is accompanied with economic growth, provided, good health, education, and employment opportunities exist (Bloom and Williamson 1998; Ross 2004). At present conditions, India will sustain demographic dividend for 37 more years and thus, the health of children is an important aspect as it tells about the past and also the future of the workforce (UNICEF 1998). In 2020, India ranked 94 out of 107 countries in Global Hunger Index, third economy out of 181 in GDP (PPP) and 131 out of 189 countries in Human Development Index. The level of hunger in India is categorized as serious (Global Hunger Index 2020). The child wasting rate is 17.3%, child stunting rate is 34.7%, and under‐five mortality rate is 3.7%; there is a 14% prevalence of undernourished children and a decreasing trend in the global hunger index score since 2000. Although, India ranked 71 out of 113 countries in food security index, and it is noteworthy that it was ranked 37 in food availability, 76 in affordability, 74 in quality and safety, and 98 in natural resources and resilience (Global Food Security Index 2020). Being a leading producer of food grains make it obvious to score well in availability of food but this merely is not enough as quality and safety are also important. Food security is composed of four dimensions, i.e. availability, access, utilization, and stability of the three dimensions over time (FAO 2008). Equitable distribution of food ensures that the good quality, available food reaches the table of every household in the nation. Failing to do so leads to hunger which means distress related to lack of sufficient calories (Global Hunger Index 2019). This leads up to another complex dimension that is malnutrition. Malnutrition refers to deficiencies, excesses, or imbalances in a person's intake of energy and/or nutrients (WHO 2021). The term malnutrition covers two broad groups of conditions one is “undernutrition” and other is overweight, obesity, and diet‐related noncommunicable diseases (WHO 2021). Undernutrition is defined as the outcome of insufficient food intake and repeated infectious diseases, it includes being underweight for one's age, too short for one's age (stunted), dangerously thin for one's height (wasted), and deficient in vitamins and minerals (micronutrient malnutrition) (UNICEF). Stunting is an indicator of chronic undernutrition, the result of prolonged food deprivation and/or disease or illness; wasting is an indicator of acute undernutrition, the result of more recent food deprivation or illness; underweight is used as a composite indicator to reflect both acute and chronic under nutrition, although it cannot distinguish between them (WHO 1995). Undernutrition has been a cause of health issues in developing countries (Rice et al. 2000; Schofield and Ashworth 1996; WHO 2002). This is a matter of concern because; stunting affects the mental development of the child and reduces their productive efficiency (Mendez and Adair 1999). Thus, posing a risk on the future of nations and emerging as a public health challenge. Not only this, the economic losses caused by malnutrition are 11% of GDP every year in Africa and Asia, whereas the rate of return on investment in prevention is $16 for each dollar invested (Global Nutrition Report 2016). Thus, preventing malnutrition is an economically viable option.

India is opting for a multipronged approach to tackle the burden of malnutrition through nutritional programmes like Mid‐day meals, Integrated Child Development Programme, Public Distribution System (PDS), National Nutrition Mission, Bio‐fortification, etc. Bio‐fortification is the process of using conventional plant breeding techniques to enrich staple food crops with higher level of vitamin A, zinc, and iron. PDS in India covers a large amount of beneficiaries who are unable to afford a minimum dietary requirement. Distribution of bio‐fortified wheat though PDS can help
