Food security is a rising concern around the world, especially in developing countries within arid and semi-arid regions. Ecosystem provides different services to support living and human survival, which includes some major food sources around the world like agriculture, fisheries, and livestock. With advancing times, humans improved these services and produced enough food to support the rising population. However, with increasing greenhouse gases, a new problem came into existence, commonly known as climate change (CC), which accelerated issues like food security and safety. Under such issues, people don't have access to basic facilities and food supply to survive, and with future population growth estimates, it is becoming even more difficult. Some major food sources together with alternate sources are discussed in this chapter. Upcoming CC impacts are discussed in detail in relation to major food sources and supported by world maps to provide a better picture. Major actions, government initiatives, and some suggestions are also provided to overcome this global crisis.

Although global food production has consistently kept pace with population growth, the gap between food production and demand in certain parts of the world is likely to remain. More than 800 million people in developing countries lack access to a minimally adequate diet. Continued productivity gains are essential on the supply side, because global population will increase by 73 million people a year over the next two decades. In this article we assess the current global food situation, look at the prospects through to the year 2020, and outline the policies needed to achieve food security for all. Emphasis is on the role that agricultural biotechnology might play in reaching this goal.

Climate prediction models suggest that agricultural productivity will be significantly affected in the future. The expected rise in average global temperature due to the higher release of greenhouse gases (GHGs) into the atmosphere and increased depletion of water resources with enhanced climate variability will be a serious threat to world food security. Moreover, there is an increase in the frequency and severity of long-lasting drought events over 1/3rd of the global landmass and five times increase in water demand deficits during the 21st century. The top three cereals, wheat (Triticum aestivum), maize (Zea mays), and rice (Oryza sativa), are the major and staple food crops of most people across the world. To meet the food demand of the ever-increasing population, which is expected to increase by over 9 billion by 2050, there is a dire need to increase cereal production by approximately 70%. However, we have observed a dramatic decrease in area of fertile and arable land to grow these crops. This trend is likely to increase in the future. Therefore, this review article provides an extensive review on recent and future projected area and production, the growth requirements and greenhouse gas emissions and global warming potential of the top three cereal crops, the effects of climate change on their yields, and the morphological, physiological, biochemical, and hormonal responses of plants to drought. We also discuss the potential strategies to tackle the effects of climate change and increase yields. These strategies include integrated conventional and modern molecular techniques and genomic approach, the implementation of agronomic best management (ABM) practices, and growing climate resilient cereal crops, such as millets. Millets are less resource-intensive crops and release a lower amount of greenhouse gases compared to other cereals. Therefore, millets can be the potential next-generation crops for research to explore the climate-resilient traits and use the information for the improvement of major cereals.

Global food insecurity is becoming more severe under the threat of rising global carbon dioxide concentrations, increasing population, and shrinking farmlands and their degeneration. We acquired the ISI Web of Science platform for over 31 years (1988–2018) to review the research on how climate change impacts global food security, and then performed cluster analysis and research hotspot analysis with VosViewer software. We found there were two drawbacks that exist in the current research. Firstly, current field research data were defective because they were collected from various facilities and were hard to integrate. The other drawback is the representativeness of field research site selection as most studies were carried out in developed countries and very few in developing countries. Therefore, more attention should be paid to developing countries, especially some African and Asian countries. At the same time, new modified mathematical models should be utilized to process and integrate the data from various facilities and regions. Finally, we suggested that governments and organizations across the world should be united to wrestle with the impact of climate change on food security.

С 1988 года начался новый период экономических и политических отношений России с развивающимися странами Азии, Африки и Латинской Америки. Особо тесные торговые и финансовые отношения России сложились и поддерживаются с Венесуэлой, Бразилией, Индией, Эфиопией, Ливией, Ганой, Алжиром, Нигерией, Сирией, Ираком и другими развивающимися странами. Но с 2019 года это взаимодействие усложнилось в связи с мировым кризисом вследствие пандемии Covid-19. Все страны мира были вынуждены вносить коррективы в свои внешнеэкономические связи. Since 1988, a new period of economic and political relations between Russia and the developing countries of Asia, Africa and Latin America began. Particularly close trade and financial relations of Russia have developed and are maintained with Venezuela, Brazil, India, Ethiopia, Libya, Ghana, Algeria, Nigeria, Syria, Iraq and other developing countries. But since 2019, this interaction has become more complex due to the global crisis due to the Covid-19 pandemic. All countries of the world were forced to make adjustments to their foreign economic relations

Abstract. While the Emissions Database for Global Atmospheric Research (EDGAR) focuses on global estimates for the full set of anthropogenic activities, the Land Use, Land-Use Change and Forestry (LULUCF) sector might be the most diverse and most challenging to cover consistently for all countries of the world. Parties to United Nations Framework Convention on Climate Change (UNFCCC) are required to provide periodic estimates of greenhouse gas (GHG) emissions, following the latest approved methodological guidance by the International Panel on Climate Change (IPCC). The current study aims to consistently estimate the carbon (C) stock changes from living forest biomass for all countries of the world, in order to complete the LULUCF sector in EDGAR. In order to derive comparable estimates for developing and developed countries, it is crucial to use a single methodology with global applicability. Data for developing countries are generally poor, such that only the Tier 1 methods from either the IPCC Good Practice Guide for Land Use, Land-Use Change and Forestry (GPG-LULUCF) 2003 or the IPCC 2006 Guidelines can be applied to these countries. For this purpose, we applied the IPCC Tier 1 method at global level following both IPCC GPG-LULUCF 2003 and IPCC 2006, using spatially coarse activity data (i.e. area, obtained combining two different global forest maps: the Global Land Cover map and the eco-zones subdivision of the Global Ecological Zone (GEZ) map) in combination with the IPCC default C stocks and C stock change factors. Results for the C stock changes were calculated separately for gains, harvest, fires (Global Fire Emissions Database version 3, GFEDv.3) and net deforestation for the years 1990, 2000, 2005 and 2010. At the global level, results obtained with the two sets of IPCC guidance differed by about 40 %, due to different assumptions and default factors. The IPCC Tier 1 method unavoidably introduced high uncertainties due to the "globalization" of parameters. When the results using IPCC 2006 for Annex I Parties are compared to other international datasets such as (UNFCCC, Food and Agriculture Organization of the United Nations (FAO)) or scientific publications, a significant overestimation of the sink emerges. For developing countries, we conclude that C stock change in forest remaining forest can hardly be estimated with the Tier 1 method especially for calculating the C losses, mainly because wood removal data are not separately available on harvesting or deforestation. Overall, confronting the IPCC GPG-LULUCF 2003 and IPCC 2006 methodologies, we conclude that IPCC 2006 suits best the needs of EDGAR and provide a consistent global picture of C stock changes from living forest biomass independent of country estimates.
