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.

(1) Background: COVID-19 has exacerbated global food security risks, and the global food supply chain, especially in developing countries, has become more vulnerable. (2) Methods: In this paper, we discussed the current security of global food, response measures, and potential impacts, and analyzed the characteristics and evolution of food security policies in four representative countries: China, Italy, Malawi, Argentina. (3) Results: The results showed that most countries give priority to ensuring food access. Most underdeveloped countries adopt humanitarian intervention measures such as food distribution and transfer payments, while developed countries tend to implement development intervention policies such as supporting small- and medium-sized enterprises and guaranteeing employment. (4) Conclusions: Despite the ample global supply, developing countries still face long-term food security risks, highlighting the importance of strengthening global food security governance and risk management. Finally, a food security risk response policy framework was built to provide suggestions for effectively handling COVID-19 and similar public health emergencies in the future.

The signals of global warming are now being observed throughout the world. Data of hydrometeorological centres show a significant increase of temperature in many regions accompanied by intense frequency of dry periods. Some substantial and direct effects of climate change may be already noticed at present time. Over the next several decades they will be observed in agriculture. Increase of temperature and reduction of precipitation volumes will probably lead to decrease the level of yield. These changes can significantly affect the global food security. Ukraine is known for its fertile soil and agricultural products, so it has a huge agricultural potential, contributing, in fact, to the global food security. However, the observed weather changes, increase of average temperature and uneven distribution of rainfalls can result in sharp transformation of most of agricultural and climatic zones of Ukraine. According to international processes there is an urgent need for improvement of adaptation to climate change of some branches of national economy of Ukraine, including of agriculture. Expanding the range of types of millet used in agricultural production is an economically feasible process that should be implemented in view of significant climate changes resulting in global warming which is widely discussed in scientific literature. Rapid introduction in crop shifts of the millet that is able to withstand recurring periodic droughts, especially in the southern regions, is one of the ways allowing to overcome the consequences of such extreme conditions. Conditions of the southern regions are favourable for millet crop. Millet is one of the most drought-resistant and heat-resistant crops that can sustain heat injuries and seizures and this is very important for arid areas during dry years, when other crops significantly reduce the level of yield. We studied changes of agro-climatic resources and agro-climatic conditions for formation of millet productivity for various periods of time. The analysis of climate change trend was performed through comparing of data as per climatic scenarios A2 and A1B and of average long-term characteristics of climatic and agro-climatic indicators. The comparative description of millet productivity under the conditions of climate change as per average long-term data (1986-2005) and as per scenarios A2 and A1B of climate change (2011-2030 and 2031-2050) was also performed.

Abstract Food security is the main path to develop the socioeconomic status in any country in the world to defeat malnutrition. The present scenario in an under developed countries are still facing this problem. Hence the human nutrition deficiencies focus on the importance of animal protein in their regular diet. To overcome this problem, fisheries contribute a significant amount of animal protein to the diets of people worldwide. The aquatic animals are the highly nutritious and cheapest protein sources, which serves as a valuable supplement in diets by providing essential vitamins, proteins, micronutrients, and minerals, for the poor people. Aquaculture is playing a vital role in the developing countries in national economic development, and global food supply. Food and agricultural organization (FAO) declared that this aquaculture has the continuous potentiality to create a developmental goals for the country economy and better human welfare.
