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.

Since its early rudimentary forms, phosphate fertilizer has developed in step with our understanding of successful food production systems. Recognized as essential to life, the responsible use P in agriculture remains key to food security.

<span>Subsistence-based and natural resource-dependent societies are especially vulnerable to climate change. In such contexts, food security needs to be strengthened by investing in the adaptability of food systems. This paper looks into the role of agrobiodiversity conservation for food security in the face of climate change. It identifies agrobiodiversity as a key public good that delivers necessary services for human wellbeing. We argue that the public values provided by agrobiodiversity conservation need to be demonstrated and captured. We offer an economic perspective of this challenge and highlight ways of capturing at least a subset of the public values of agrobiodiversity to help adapt to and reduce the vulnerability of subsistence based economies to climate change.</span>

The contribution of seafood to global food security is being increasingly highlighted in policy. However, the extent to which such claims are supported in the current food security literature is unclear. This review assesses the extent to which seafood is represented in the recent food security literature, both individually and from a food systems perspective, in combination with terrestrially-based production systems. The results demonstrate that seafood remains under-researched compared to the role of terrestrial animal and plant production in food security. Furthermore, seafood and terrestrial production remain siloed, with very few papers addressing the combined contribution or relations between terrestrial and aquatic systems. We conclude that far more attention is needed to the specific and relative role of seafood in global food security and call for the integration of seafood in a wider interdisciplinary approach to global food system research.

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.

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.

The COVID-19 pandemic and locust swarm outbreaks pose a significant threat to global food systems, causing severe disruptions in both local and international food supplies from farm to fork. The main objective of this study is to understand and identify the disruptions during the crises and create a map of how resilience can be established to recover and sustain the food supply chain (FSC) functions as well as food security. The detrimental impacts of the compound crises on the FSC are explored and the effects of the affected areas are estimated under optimistic and pessimistic scenarios. As a response to the disruption caused by the crisis in FSCs, reactive and proactive solutions are proposed to develop resilience at the food sector level. In the short term, the reactive solutions, consisting of smoothing the food demand, supply and delivery, and food production and processing, can be borrowed. In the long term, the proactive solutions can be conducted by developing multi-level short intertwined FSCs. Our comprehensive investigation of the resilience elements in diverse operations and potential strategies should contribute to the improvement of FSC resilience in the face of ongoing and growing threats.

Climate change poses unprecedented and complex challenges to global food systems. Critical vulnerabilities, continuing inequalities, and unsustainability have demonstrated that food systems need significant intervention in order to deliver safe, just, and healthy food for all, against the backdrop of a changing climate. Innovative interventions and effective financing are needed across the food system to achieve these grand ambitions. While there is recognition of a systems approach in the face of complex issues such as climate change, interventions and financing mechanisms have historically focused narrowly on production or specific sectors within food and related systems. Given the diverse array of stresses and shocks, this approach will not achieve the desired paradigm shifts necessary to secure global food systems and meet the Paris Agreement climate targets. Through a comprehensive review of projects funded through the Green Climate Fund (GCF), this paper shows that paradigm shifting interventions can benefit from a food systems perspective by moving beyond specific sectors and activities and delivering outcomes across the socio-economic and environmental spheres. Climate change and food system challenges are complex and necessitate system approaches, and financing instruments need to be designed and structured with systemic complexity in mind.
