With the Climate change effects becoming more and more undoubted in the world populations, the reality of food production trends taking a negative curve is clear. This bring up the questions of whether the farmers will be able to produce food for the sustenance of the world population or not? The rate of developing food shortage coping mechanisms in this regard is slower that the ravaging negative climate change effects of drought and floods on farm performance. This commentary has the aim of requesting a fresh discussion around the fundamentals of what is food, what is a food security and what is nutritional security? It is possible that the humanity has a perception that needs refocusing. This is a perception that some people may choose out of non-food safety issues not to eat certain foods while other however healthily eat such food. It therefore becomes hard to technically accept that food is in short supply for those the opt not to eat that which is edible.

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.

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.

Global food security is one if the major issues that needs utmost attention of the scientific community in near future. The growing food demand of the society is putting enormous pressure on the resources over which the food supply of the civilization depends. The two major components affecting the global food security are population and global climate change. The rate at which the population of the World is increasing, the food production needs to be doubled to meet the growing requirements. Consequences of global climate change not only reduce the productivity of major staple crops, but also cause destruction of the arable land that can be used for agricultural purposes. The present chapter discusses the effects of population increase and climate change upon food production, which will play a significant role in food security around the globe in near future.
