Climate change is a global issue, which impacts the different geographical zones in different levels. It is also linked to numerous human health issues, which are a concern to human health. The impact of climate change on traditional methods of food preservation in Nigeria and the consequences for food security and health are examined in this research. Information from the Nigerian Meteorological Agency (NIMET) and the National Emergency Management Agency (NEMA) show that average temperatures are increasing and rainfall is decreasing, which are effects of climate change that affect agriculture, water resources, and traditional food preservation methods that are detrimental to public health.Traditional food preservation methods are critical for understanding the link between climate change and food security.This paper uses a case study of Nigeria to examine the effects of climate change on traditional food preservation practices and public health. The research focuses on the shifts in the conventional preservation techniques, the impact of these shifts on nutrition, and policy interventions for enhancing sustainable preservation of food. Climate change indicators such as temperature and rainfall were used as surrogates for climate change, food insecurity such as undernourishment rates were used for food security and nutritional health outcomes such as child stunting and micronutrient malnutrition. The study shows that climate change has a negative effect on food security since it reduces crop yields and enhances post-harvest losses. Sun-drying and smoking are the common preservation techniques that are now less efficient because of high humidity and unpredictable weather. As such, people are experiencing increased incidences of food wastage, nutritional imbalance, and food borne diseases especially with those people in rural regions. Furthermore, the study confirms the relationship between climate change and food insecurity, which has a negative impact on the health of pregnant women and children, especially under five years, and high under-five mortality despite a decrease in child mortality in the last decade.The results provide important regional information relevant to the entire Sub-Saharan Africa and useful to the international community in matters of climate change, food security and health. This study calls for the use of innovation that combines the conventional and contemporary methods of food preservation in order to mitigate the impacts of climate change on food security systems. Furthermore, it underlines the need for the policy interventions that may prevent food borne illness and other diseases. These insights are in line with the United Nations Sustainable Development Goals (UN-SDGs) 2, 3, and 13, namely; Zero Hunger, Good Health and Well-being, and Climate Action, respectively.This research addresses a significant gap in the literature by linking climate change effects with food preservation practices and offering recommendations for improving food system vulnerability to climate change. It provides a clear picture of the prospects and constraints of mitigating climate change impacts on food insecurity and enhancing food security and health in the world.
