Abstract Agricultural diversification of intensified farming systems is being proposed as a solution for achieving both food security and agricultural sustainability, but so far there has been little implementation of such policy at a larger scale. In China, major policies promote the “High-standard farmland consolidation” (HSFC) strategy to improve productivity and reduce environmental degradation in the world’s largest food production areas by simplifying instead of diversifying landscapes on large instead of small fields. As China’s Central government is asking for scientific innovations to improve its sustainable development strategy, we argue that China can become a role model to integrate agricultural diversification in its major policies, if HSFC builds on five decades of diversification research to achieve the national food security and sustainable development goals. We use text mining to analyze the past 17 years of China’s most important agricultural policy, the No. 1 Central Documents (1CD) policy and show that agricultural diversification at the field and supply chain level has received limited attention. Based on global synthesis studies covering five decades of research, we provide practical recommendations of how to integrate agricultural diversification in the China’s major policies from the national (the National 5-Year Plan and 1CD) to the provincial level. We use the major agricultural commodities rice, tea, wheat, and rapeseed in Zhejiang province as a case study to discuss how diversification can help to reach China’s sustainable agriculture targets. Diversification of China’s major food production areas on small fields could be an important example globally of how scientific progress informs policy and facilitates the food system transition.

The Republic

One of the most important components of national security is food security. The country's food security is mainly ensured through the development of agriculture, food production and food import systems. The main problems of the development of the agri-food system of the republic were the increase of the level of provision of the population with food, the increase of the level of economic protection of the country, which, first of all, requires an increase of agricultural production to provide the population with locally produced food products, raw materials to the processing industry as much as possible, as well as to increase export volumes. The main goal of the research is to develop and outline the ways of further development of the RA food self-sufficiency based on the development of agricultural production. Based on the analysis of the current situation in the agricultural market, to propose a set of economic development measures, which will contribute to the increase of the food security level, the development of the agri-food system, the reduction of the poverty level of the rural communities. The research substantiated the preconditions for further growth of agricultural production, as a result of comprehensive studies and analyzes, the main directions of improving food production and increasing efficiency were outlined, which conditioned the scientific novelty.

Food system transformation has been a widely discussed topic in international society over time. For the last few decades, China has made remarkable achievements in food production and has contributed greatly to the reduction in global hunger and poverty. Examining experiences and lessons from China’s food security practices over the years is helpful to promote a national food system transformation for China, as well as other developing countries. This study systematically reviews the literature on Chinese food security studies, with the aim of assessing China’s food security achievements and examining the remaining and emerging issues in the pursuit of food system transformation. The results show that China has continuously promoted food system transformation in land consolidation, agri-food production technologies, management and organization modes, food reserves, trade governance, and food consumption. These transformations ensure not only food availability, timeliness, and nutrition, but also in terms of the ecological, social, and economic sustainability, feasibility, and justice of food security. However, China is also confronting new challenges in food security, for example, malnutrition, environmental unsustainability, and reductions in diversified agri-food. In the future, China is expected to be committed to promoting healthy diets, sustainable agricultural production, climate change mitigation, and the reduction of food waste and loss to enhance its agri-food system’s resilience.

Quantified components of the global food system are used to assess long-term global food security under a series of socio-economic, epidemic normalization and climate change scenarios. Here, we evaluate the global food security including the global farming system as well as the global food trade, reserve and loss systems from 1961 to 2019, and analyze their temporal and spatial characteristics by using the global food vulnerability (GFV) model. The spatio–temporal patterns of the vulnerability of the global food system were consistent with the GFSI. As food production and consumption vary greatly in different countries which have continued for a long time, food exports from many developed agricultural countries have compensated for food shortages in most countries (about 120 net grain-importing countries). As a result, many countries have relied heavily on food imports to maintain their domestic food supplies, ultimately causing the global food trade stability to have an increasing impact on the food security of most countries. The impact of global food trade on global food security increased from 9% to 17% during 1961–2019, which has increased the vulnerability of the global food system. The food damage in the United States, Russia, China, and India has varied significantly, and global cereal stocks have fluctuated even more since 2000. From 1961 to 2019, the food system security of some Nordic countries significantly improved, while the food system security of most African countries significantly deteriorated. Most countries with high food insecurity are located in Africa and South Asia. In order to cope with extreme events, these countries need to strengthen and improve their own food production and storage systems, which will help the World Food and Agriculture Organization to formulate relevant food policies and maintain sustainable development.

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.

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.

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).

AbstractWith food security increasingly seen as an urban concern, urban agriculture (UA) has emerged as one strategy for improving access to healthy, affordable food within cities in the Global North. This research evaluates the contributions of three types of urban gardens in Santa Clara County, California, to food security. Survey, interview and harvest data were collected from home gardeners, community gardeners and gardeners participating in community food security (CFS) programs, which provide low-income families with the materials and training to grow their own vegetables. To assess food security we use a multi-dimensional framework that encompasses food availability, accessibility, nutritional adequacy and cultural acceptability as well as agency within the food system. Over the summer of 2015, median garden production ranged from 26 kg for participants in CFS programs to 56 kg for home gardeners. All garden types produced enough produce for at least one adult to consume the number of cups of vegetables recommended by federal nutritional guidelines. Gardening also increased some low-income gardeners’ access to healthy food, allowing them to have the diet they wanted—one high in organically grown vegetables—but could not otherwise afford to purchase. Interviews showed that gardeners do not think of cultural acceptability strictly in terms of the presence of certain types of cultural crops; they also articulated a broader set of values concerning the environmental and social conditions of food production. At all income levels, gardeners frequently described a set of food values related to knowledge, control, trust, freshness, flavor, organic production methods and sharing, which they were able to enact through gardening. Taken together, these findings demonstrate the nutritional contributions that urban gardens make but also highlight the importance that low-income gardeners place on having food that aligns with their cultural and ethical values and being able to exercise greater autonomy in making food choices. In conclusion, we suggest that more robust, holistic assessments of UA's contributions to food security will include the subjective aspects of food as well as quantitative measures related to food production.

In the backdrop of climate change, jack fruit (Artocarpus heterophyllus) plays an important role in ensuring food security. The fruit belongs to the Moraceae family and the largest edible fruit in the world. Its a large ungainly fruit grown across India especially in every part of Kerala and by 2018 Government of Kerala designated Jackfruit as the state fruit. During rainy season jackfruit is a staple food for many communities especially in hilly areas where they can use as supplement food with rice to meet nutrition security especially in tribal areas. Its far more nutritious than mangoes, oranges and other tropical fruits and having all the common starch. Its community food and commonly used by different communities in India, specially communities in hilly areas during rainy season from June –November. The four dimensions of food security, (i.e., Food Availability+ Food Access+ Food Utility + Food Stability) also cope with Environmental influence (Food Consumption +Food Production +Food Distribution). It moves beyond the concept of food supply to provide a comprehensive package for individuals to reach a state of nutritional well-being in which all physiological needs are met. Jack fruit is commercially viable for farmers as an average farmer get 50 kg from each tree and earn Rs 3000 apart from wood for fuel and leaves for domestic animals. It ensures food security in terms of (Food Availability=10,000Kg/Acre Food Access (Appropriate foods for a nutritious diet) =95 kcal Food Utility=40,000 Families/Acre i.e. 4member/Kg and Food Stability= 6 months).A community food system is a food system in which food production, processing, distribution and consumption are integrated to enhance the environmental, economic, social and nutritional health of a particular place (Garrett and Feenstra, 1999) i.e. realizing a food secure community. A food secure community is a place where all community residents obtain a safe, culturally appropriate, nutritionally sound diet through an economically, socially and environmentally sustainable food system that promotes community self-reliance and social justice (Hamm & Bellows, 2002). There are many communities whose staple food is jackfruit. The Kaani tribal community, Kanyakumari forests, of the Western Ghats, were a nomadic tribe solely dependent on Jack fruit (Artocarpus heterophyllus), and is a major staple food apart from tapioca. Despite its versatility as a tree species for general afforestation and for agroforestry programs research attention should be given on to involve jack fruit trees under system which are yet to be evolved.
