Global food security is one of the most unrelenting issues for humanity, and agricultural production is not sufficient in accomplishing this. However, earlier analyses of agricultural food production barely ever bring out the contrasts associated with economic development and different climatic zones. The world population is increasing day by day and climate change will be causing more extreme weather, higher temperatures and changed precipitation. The crop contributes about 20 % of the total dietary calories and proteins globally. There is 1% annual growth in food demand in the developing regions. The developing regions (including China and Central Asia) account for roughly 53 % of the total harvested area and 50 % of the production. Although, unmatched productivity growth from the Green Revolution since the 1960s dramatically transformed world food production, benefitting both producers and consumers through low production costs and low food prices. One of the key challenges today is to replace today’s food system with new ones for better sustainability. While the Green Revolution freed essential ecosystems from conversion to agriculture, it also created its own ecological problems. Moreover productivity increase is now slow or stagnant. Attaining the productivity gains needed to ensure food security will therefore require more than a repeat performance of the Green Revolution of the past. Future demand will need to be achieved through sustainable intensification that combines better crop resistance plants, adaptation to warmer climates, and less use of water, fuel, fertilizer, and labor. Meeting these challenges will require concerted efforts in research and innovation to develop and set up feasible solutions. Necessary investment will be required to realize sustainable productivity growth through better technologies and policy and institutional innovations that facilitate farmer adoption and adaptation. The persistent lessons from the Green Revolution and the recent efforts for sustainable escalation of food systems in South Asia and other developing nations will definitely providing useful insights for the future.

Long Run

There is an ongoing debate about how best to feed the growing world population in the long run and associated implications for research and development. Some call for a new Green Revolution to secure the supply of staple foods, whereas others emphasize the importance of diversifying and improving people's diets. We aim to contribute to this debate by reviewing the case of wheat and maize value chains and their contribution to food security in Africa and Asia. We first identify drivers transforming food systems. We then apply these to the cereal value chains and disentangle their effects on food security. We thereby add to the three strands in the literature around production, consumption, and food system transformation and point to different research needs and recommendations for the future. The review highlights: (1) Wheat and maize production will be increasingly impaired by ecological drivers such as land degradation, water scarcity and climate change. (2) There are promising innovations to increase and maintain productivity, but constraints in adopting these innovations have to be overcome (i.e., access to seeds, finance, and education/training). (3) The drivers affect all four dimensions of food security, but first and foremost they determine the availability and stability of maize and wheat. This indirectly also influences the economic and physical access of people to maize and wheat. (4) Research tends to focus on improving the productivity and sustainability of wheat and maize farming which is largely interlinked with the availability dimension of food security. (5) The stability and utilization dimension of food security merits continued yet increased support. First, to address climate change and implications for biotic and abiotic stresses. Second, to promote healthier diets and enable the equitable transformation of food systems.

Abstract Background  World population is projected to reach 9–11 billion by 2050, raising concerns about food system security and sustainability. Modeling food systems are often a way to understand current and future dynamics. The most common model, first articulated by Malthus (Malthusian), shows population growth as an exponential function and food production as a linear function, concluding that human carrying capacity will be reached leading to mass starvation. Another prominent model was introduced by Boserup (Boserupian), which explains increases in food production as a function of population growth. Methodology  Here, we explore which food systems dynamics exist at equilibrium and after perturbation. The model introduced explores food availability in an isolated village and then in a line of villages. The isolated village model includes three key parameters: maximum calorie production (a), food production resilience (b), and minimum calorie requirement per person (c). The multiple village model adds an additional parameter for trade. Results  Isolated village populations are more resilient to famine than Malthusian theory predicts, suggesting that Malthus’ premise may be inaccurate. Predictably, across multiple villages increasing access and production reduce famine. However, under certain conditions large amounts of transport can lead to antagonist relationships leading to rapid changes in population. Conclusion  Food systems under both production and access scenarios proved to be resilient to small perturbations, requiring a large catastrophe to induce mortality; this appeared to discount the Malthusian model. This model can create dynamics where different modes of famine relief apply, but here we see that a balanced approach of both access and production appears to be the most resilient to famine.

Purpose – The purpose of this paper is to investigate if religious food laws can provide answers to current issues with the food systems. Design/methodology/approach – This paper provides a discussion of the dietary and food system principles from a Judaism, Christianity and Islamic perspective for the design of a more sustainable and healthy food system. Findings – The commercialisation of the natural resources, industrial food production approach and consumerism is endangering the food security, health and environment. Current industry practices are not sustainable and do not comply with Jewish, Christian and Islamic scriptures. Kosher, Christian and halal food laws share common principles in prohibition of certain animals (like pig), prohibition of blood, role of fasting and animal welfare. As a change in the diet is the solution, there is a key role for the food industry to comply and for religious leaders to radically reduce meat consumption and food waste of its followers. Research limitations/implications – This viewpoint paper shows that religious food laws provide answers to current problems with the industrialised food production approach and consumerism. Practical implications – New food industry directives should convert meat-based to plant-based ingredients and additives; replace porcine by bovine sources; and emphasise on animal welfare to better serve the Jewish, Christian and Muslim consumer. Religious logos (kosher and halal) should incorporate nutrient profiling through a traffic light system to promote healthy food choice. Originality/value – Religious food laws are important for a big part of the world population (Jews, Christians and Muslims), which share many common principles. This study contributes to a better understanding of the commonalities and differences in these religious food laws.

Studies of livelihoods and food systems since the start of the global pandemic in 2020 have shown a consistent pattern: the primary risks to food and livelihood security are at the household level. Covid-19 is having a major impact on households’ production and access to quality, nutritious food, due to losses of income, combined with increasing food prices, and restrictions to movements of people, inputs and products. The studies included in this Research for Policy and Practice Report and supported by the Covid-19 Responses for Equity (CORE) Programme span several continents and are coordinated by leading research organisations with a detailed understanding of local food system dynamics and associated equity and livelihood issues in their regions: (1) the impact of the Covid-19 pandemic on livelihoods in sub-Saharan Africa; (2) supporting small and medium enterprises, food security, and evolving social protection mechanisms to deal with Covid-19 in Pakistan; and (3) impact of Covid-19 on family farming and food security in Latin America: evidence-based public policy responses.

Food And Nutrition

The 2007-2008 food crises and the renewed surge in food prices in 2010-2011 have exposed deep structural problems in the global food system and the need to increase food production. The World Food Summit of 1996 defined food security as existing "when all people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life". Despite Nepal has no worse food and nutrition security situation among SAARC countries, there are some districts where food is always in shortage. The explicit constitutional recognition of the right to food and other related provisions in articles 36 and 42 of the new constitution will be instrumental for implementing food security programs in the country. Food security for poor people is based on sustainable food production. Many proven technologies and improved practices have the promise to boost agricultural production and ensure food security in developing countries like Nepal. Food and Nutrition security program (FANUSEP) is one of the flagship programs of Agriculture Development Strategy 2015-2035 (ADS), which is in the first phase of its implementation. It aims at improving the food and nutrition security of the most disadvantaged groups of the population.

There is an urgent need to match food production with increasing world population through identification of sustainable land management strategies. However, the struggle to achieve food security should be carried out keeping in mind the soil where the crops are grown and the environment in which the living things survive, especially under rainfed agricultural system. Rainfed agricultural ecosystem is extremely fragile, improving soil fertility and reducing greenhouse gas emission are key factors for developing sustainable agriculture. Moreover, society increasingly expects agriculture to be more sustainable, by decreasing irrigation and mineral fertilizer inputs. Increasing food production sustainably through efficient use of resources will strongly contribute to food security, sustainable agriculture development, and increased climate change resilience. This paper addresses the effects of carbon smart technologies on greenhouse gas emission, soil quality and crop productivity in rainfed agro ecological environment. This paper hypothesized that application of carbon smart technologies could improve soil physical and chemical properties to enhance GHG mitigation and crop production. Carbon smart technologies highlighted in this paper include minimum tillage, crop residue retention, agroforestry, biofuels, integrated nutrient management and land use management systems. This paper review and discusses the work done on carbon smart technologies in different agro-ecological regions so as to understand its impact from the perspectives of the soil, the crop and the environment. The impact of conservation agriculture on greenhouse gas emissions and the underlying mechanism in different agroecological environments have been discussed. A detailed case study and tremendous advancements on the strength of integration of trees and shrub as carbon smart technologies in improving soil and crop productivity is highlighted immensely. The paper concludes with recommendations for encouraging and improving adoption by smallholder farmers to ensure more efficient and sustainable food system. This systematic review will primarily contribute to the achievement of the following Sustainable Development Goals (SDGs), particularly SDG1 (No poverty), SDG2 (Zero hunger), SDG5 (Gender equality) and SDG13 (Climate action).

Adequate Food

Abstract Worldwide nearly a billion people are estimated to be malnourished, including 140 million children under age 5, leading to permanent impairment of their physical and cognitive development (WHO; http://www.unscn.org/layout/modules/resources/files/rwns5.pdf). In addition, 1 in 9 humans worldwide do not have regular access to clean, healthy drinking water, and 1 in 4 use a drinking water source contaminated with feces [WHO (World Health Organization); https://www.who.int/news-room/fact-sheets/detail/drinking-water]. Providing adequate food and water will become an even bigger challenge during the remainder of this century given the projected nearly 50% increase in the world’s population [from its current 7.6 to 11.2 billion by 2100; Garland, Science 346:234–7, 2014 and World Population Prospects, UN, 2015 (the U.S. is projected to experience a similar increase in population; https://www.census.gov/data/tables/2014/demo/popproj/2014-summary-tables.html)]. These problems are why the top 2 of the United Nation’s 17 current “Sustainable Development Goals” are to “End poverty in all its forms everywhere” (Goal 1) and to “End hunger, achieve food security and improved nutrition and promote sustainable agriculture” (Goal 2). Because most arable land worldwide is already in use, and water and energy also are limiting, increased production of food will require a substantial increase in efficiency (Reynolds et al., Journal of Nutrition 145:1377–9, 2015). This talk will discuss how animal-sourced foods, when consumed in appropriate amounts as part of a balanced diet, provide essential nutrients for humans and are important to a healthy diet. In addition, we will discuss how animals are critical to continuation of the “Green Revolution,” which will be key to the sustainability of agricultural systems. In addition, addressing various potential problems associated with production of food animals, including water availability and quality, greenhouse gas emissions, animal welfare, overgrazing, food waste, and complexity of the food system(s), will require highly motivated and well-trained animal scientists.

The Impact

The first purpose of this chapter is to highlight the impact of the food system on environmental and human health. The delivery of secure affordable food is a political imperative. Unfortunately, the food system that delivers it is environmentally blind. Food prices do not effectively reflect the value of food and often seriously mislead on the costs and impacts of food production. For example, actual food production takes place in a failed market—the value of environmental services such as water and the supporting ecosystems are not taken into account. The second purpose is to summarize and expose the political economy of the different ‘market’ modes of the food system. It is shown that there are weak players such as underrewarded and undervalued farmers who support society by producing food and stewarding our unvalued environment. The inadequacies of accounting systems are also critiqued.

Systems Framework

Globally, gender inequalities constrain food security, with women often disproportionately affected. Women play a fundamental role in household food and nutrition security. The multiple roles women play in various areas of the food system are not always recognised. This oversight emerges from an overemphasis on one aspect of the food system, without considering how this area might affect or be affected by another aspect. This study aimed to draw on international commitments and treaties using content analysis to enhance the Global Panel on Agriculture and Food Security food systems framework by integrating a gender perspective. The study found that generally, there is a consensus on specific actions that can be taken to advance gender equality at specific stages of the food system. However, governance and social systems constraints that are not necessarily part of the food system, but have a significant bearing on men and women’s capacity to effectively participate in the food system, need to be addressed. While the proposed conceptual framework has some limitations, it offers a foundation on which researchers, policymakers and other stakeholders can begin conceptualising the interconnectedness of gender barriers in the food system.
