Currently, the global agricultural system is focused on a limited number of crop species, thereby presenting a threat to food security and supply, especially with predicted global climate change conditions. The importance of ‘underutilized’ crop species in meeting the world’s demand for food has been duly recognized by research communities, governments and policy makers worldwide. The development of underutilized crops, with their vast genetic resources and beneficial traits, may be a useful step towards solving food security challenges by offering a multifaceted agricultural system that includes additional important food resources. Bambara groundnut is among the beneficial underutilized crop species that may have a positive impact on global food security through organized and well-coordinated multidimensional breeding programs. The excessive degrees of allelic difference in Bambara groundnut germplasm could be exploited in breeding activities to develop new varieties. It is important to match recognized breeding objectives with documented diversity in order to significantly improve breeding. This review assesses the genetic diversity of Bambara groundnut, as well as important factors involved in realizing and harnessing the potential of this crop.

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.

Climate change poses significant threats to global food security and water resources. In a present study, a Global Climate Model HAD GEM2-ES under RCPs 4.5 and 8.5 was used for climate prediction study. The study spanned 46 years of baseline (1970-2015) as well as two future periods’ mid-century (MC) (2020-2050) and end century EC (2060-2090). The results showed that the temperature would increase by 1.56°C and rainfall would decrease by 98 mm in MC (2020-2050); and 3.11°C and 90 mm in EC (2060-2090), respectively under RCP 4.5. In RCP 8.5 the increase in temperature and rainfall was 2.75°C and 153 mm, respectively in MC and the corresponding values in EC was 5.46°C and 251 mm, respectively.

Genetic resources form the basis of the new era of global food security. The food crises in many developing countries, reflected by food riots correlated with food prices, have been termed the Silent Tsunami. Plant genetic resources are clearly essential to food security for the future. Fortunately, genetic resources are generally considered a public good and shared internationally. Wild relatives of crop species and their derivatives represent the reservoir of genetic diversity that will help to meet the food demands of nine billion people by 2050. New technologies from genomics bolster conventional plant breeding for enhancing traits to meet these food demands. Genetic diversity is the lifeblood of traditional and modern plant breeding. The dramatic increase in the number of biotech crops reveals the value of new genetic resources. Genetic resources will provide a gateway to a new era of global food security. Although 7.4 million plant accessions are stored in 1750 germplasm banks around the world, only a small portion of the accessions has been used so far to produce commercial varieties. Our challenge is to find better ways to make more efficient use of gene bank materials for meeting food demands in the future.

Mutation breeding for crop improvement is a technique used for over 70 years. It is a fast way to increase the rate of spontaneous genetic variation in plants contributing to global food security.  The genetic variability, created through mutagenesis i.e. physical or chemical, is an important breeding material for developing improved varieties and many studies in the field of functional genomics. The randomly generated heritable genetic changes are expressed in the mutant plants, which are selected for new and useful traits, such as high yielding, disease resistance, tolerance to abiotic stresses and improved nutritional quality. The technique helps to improve the tolerance of crop species to adverse climatic conditions, such as extremes of temperatures, drought, occurrence of pests and diseases. Through support provided by the Joint FAO/IAEA Division, significant agronomic and economic impact has been generated in many countries. The FAO/IAEA Mutant Variety Database (MVD) (http://mvd.iaea.org) demonstrates the significance of mutation induction as an efficient tool in crop improvement. The extensive use of induced mutant germplasms in crop improvement programmes resulted in releasing of more than 3,332 mutant varieties from around 228 crop species (20 July 2020).

Bovine meat and milk play a major role in the diet of humans and they have positive impact on global food security. The aim of this review work was to investigate the impact of bovine sources of meat and milk on food security in the low, medium and high income countries. Bovine source meat and milk could have impact on the nutritional, health, work, income, educational and recreational needs of humans. However, the feeding needs of bovine are mainly met with forage materials which do not compete with human foods. The beef and dairy cattle are raised mainly under the extensive system of production in the low and medium income countries, while the intensive system of production is that which is adopted majorly in the high income developed nations. The production of healthy beef and milk products may be observed to go a long way in preventing disease occurrence in both the cattle and the human consumers. The raising of fewer numbers of more genetically productive breeds of cattle under the intensive, semi-intensive and extensive systems of production could also have positive impact on global food security, sustainability and the mitigation of green house gas (GHG) emissions.
