Constant production of quality food should be a norm in any community, but climate change, increasing population, and unavailability of land for farming affect food production. As a result, food scarcity is affecting some communities, especially in the developing world. Finding a stable solution to this problem is a major cause of concern for researchers. Synergistic application of molecular marker techniques with next generation sequencing (NGS) technologies can unlock the potentials hidden in most crop genomes for improving yield and food availability. Most crops such as Bambara groundnut (BGN), Winged bean, and African yam bean are underutilized. These underutilized crops can compete with the major crops such as cowpea, soybean, maize, and rice, in areas of nutrition, ability to withstand drought stress, economic importance, and food production. One of these underutilized crops, BGN [Vigna subterranea (L.), Verdc.], is an indigenous African legume and can survive in tropical climates and marginal soils. In this review, we focus on the roles of BGN and the opportunities it possesses in tackling food insecurity and its benefits to local farmers. We will discuss BGN’s potential impact on global food production and how the advances in NGS technologies can enhance its production.

Background: Nigeria is abundant in numerous agro-ecological resources, which should make it a major exporter of food items in the world. Regrettably, it has become a major food importer as a result of food scarcity. The state of food production in the country is worsened by the phenomena of climate change and global warming. These developments have deleterious effects on agricultural activities in general and food production in particular. While there are policies and agencies in the country to combat these developments, it appears they have proved ineffective in the face of increasing inconsistency in government policies, climate change and global warming. The effect of all these phenomena on human development cannot be overemphasised. A nation that cannot feed its population cannot promote development.Aim: It is against this background that this article, within the framework of dependency theory, examines the issues of climate change, food security and sustainable human development in Nigeria.Setting: This research is descriptive in nature in the sense that it provides a detailed account of policies on climate change and food production in Nigeria. It is also exploratory because over 29 research studies were consulted and analysed in order to establish the relationship between climate change, food security and sustainable human development in Nigeria.Methods: This article utilises qualitative, descriptive research methods. This article, which is theoretical in nature, drew its arguments on both primary and secondary data, which included textbooks, journal publications and internet sources.Results: This article argues that unless concrete efforts are made to mitigate the effects of climate change and ensure increased food production, the country may experience worse cases of food crisis and human underdevelopment.Conclusion: Consequently, the article recommends, among others, environmental impact assessments before, during and after industrial production activities.

Climate change is part of us and we are unlikely to avoid its impact. Impacts of climate change are severely felt within the agricultural sector, the division that strives to ensure food and nutrition security and contribute towards sustainable development in many of the developing countries. The only way farmers can survive in the face of climate change is through adaptation, a phenomenon that needs collaborative efforts. One of the critical driving factors of climate change adaptation is farmers’ perception towards tackling it, the focus of this paper. The main objective of this paper was to assess farmers’ perception towards tackling climate change. The population of the study was emerging farmers drawn from five districts of the Limpopo province, South Africa. The study used a two-stage cluster sampling technique to select a sample size of 206 emerging farmers. The dependent variable of the study was farmers’ perception about tackling climate change while the explanatory variables consisted of their socio-economic characteristics such as age, gender, farming experience and level of education. Discriminant Analysis was used to draw comparison between groups of farmers who perceived that climate change can be tackled and those who believed it cannot be. The results showed that socio-economic characteristics such as formal education, agricultural education, age group, farming experience and off-farm occupation significantly contributed towards farmers’ perception regarding tackling of climate change. Therefore, the study recommended that stakeholders should facilitate linkage of farmers with varied sources of support.

Great progress has been made in addressing global undernutrition over the past several decades, in part because of large increases in food production from agricultural expansion and intensification. Food systems, however, face continued increases in demand and growing environmental pressures. Most prominently, human-caused climate change will influence the quality and quantity of food we produce and our ability to distribute it equitably. Our capacity to ensure food security and nutritional adequacy in the face of rapidly changing biophysical conditions will be a major determinant of the next century's global burden of disease. In this article, we review the main pathways by which climate change may affect our food production systems—agriculture, fisheries, and livestock—as well as the socioeconomic forces that may influence equitable distribution.

Staple Crops

The agricultural crop system depends on a few major staple crops such as rice, maize, wheat, sorghum, soybeans, amongst others for food production, leaving certain crops underutilized. Even though these underutilized crops have the potentials of diversifying and sustaining the food and nutrition systems while presenting different resilience to climatic conditions. As the world’s population continues to increase and climate change keeps occurring, these major staple crops are being negatively affected. This study focuses on evaluating the spatial suitability of Bambara groundnut (Vigna subterranea (L.) Verdc.), an indigenous underutilized African legume under past and future climate scenarios in Nigeria, West Africa, where farmers depend mostly on rainfed agriculture. Ten bias-corrected CMIP5 Global climate models simulation downscaled by the Coordinated Regional Climate Downscaling Experiment (CORDEX) regional climate model, RCA4 under the Representative Concentration Pathway (RCP) 8.5 scenario was used to drive the crop suitability model-Ecocrop. The spatial changes in Bambara groundnut suitability were evaluated under 1 past climate period -historical (1980-2010), and 3 future climate period - near future (2010-2040), mid-century (2040-2070), and end century (2070-2099). Our result projects southern Nigeria to remain suitable and an increase in the suitable areas across other parts of the country in future climates. Projected changes were observed in the planting month for Bambara groundnut. The study is relevant and will contribute to the discussions of increasing the number of crops cultivated under climate change as an adaptation strategy towards ensuring a sustainable food system in Nigeria.

Agricultural and food production systems in Asia must undergo a significant transformation in order to meet the concurrent challenges of increasing food, water, and energy demands amid on-going climate change. This is particularly true in countries in South Asia, including Pakistan, where hunger and undernutrition persist and natural resource are increasingly strained. Sustainable intensification with a focus on nutrition is particularly crucial to provide adequate and nutritious food for all without further damages to the planet. However, a silo approach to meeting the demands of a growing, increasingly urbanised, and wealthier population is no longer acceptable. Instead, capitalising on the inter sectoral linkages between food, water, and energy can more effectively minimise trade-offs and maximise synergies across concurrent efforts to improve water, energy, food, and nutrition security sustainably.
