Effects of Climate Change on Food Security and its Relationship to Malnutrition and Vitamin Deficiencies in Vulnerable Human Populations

Abstract

Climate change is another international concern with significant implications for food security, particularly for vulnerable groups. Weather changes, increasingly frequent extreme events, and variation in agricultural productivity disrupt food availability, access, and stability, and place people at risk of malnutrition and micronutrient deficiencies. The paper discusses the relationship between climate change, food security, and the prevalence of malnutrition and vitamin deficiencies, with greater emphasis on the most vulnerable populations in the developing world and low-income communities. Besides posing health risks to humans, climate change also endangers animals, with livestock and wildlife populations most affected and susceptible to the same environmental stressors. The objectives include examining the impacts of climate change on food systems, nutrition, and health, with particular reference to vitamin A, D, and iron deficiency. These may be achieved through the review of existing literature, case studies, and statistical analysis of climate, agricultural, and health data. The results of the research have shown that climate change is one of the contributing factors to food insecurity in food distribution and crop production, with the impact of lowering the availability of nutrient-rich foods. Consequently, malnutrition and vitamin deficiencies are becoming more common among vulnerable populations. Some of the measures that would be prescribed by the study to improve food security would include the enhancement of the resilience of agriculture, diversification of food, and the augmentation of the public health interventions, which entail the use of micronutrient supplementation.
