Climate change has emerged as one of the most pressing global challenges of the twenty-first century, influencing not only environmental conditions but also the very foundations of human security. Human security, as a multidimensional framework, extends beyond the absence of conflict to include economic, food, health, environmental, personal, community, and political dimensions. The impacts of climate change on these seven dimensions are profound, particularly in developing countries, where vulnerability is exacerbated by socioeconomic inequality, weak infrastructure, and limited adaptive capacity. Economic security, which ensures stable and sufficient income and resources to maintain a basic standard of living, is directly threatened by climate change. Developing countries, often dependent on agriculture, fisheries, and natural resources for livelihoods, face substantial economic disruptions due to shifting weather patterns, droughts, floods, and cyclones. For instance, prolonged droughts in sub-Saharan Africa have decimated crop yields, reduced income for farmers, and increased dependency on external aid. Similarly, in South and Southeast Asia, floods and cyclones destroy infrastructure, homes, and marketplaces, disrupting local economies and reducing employment opportunities. These climate-induced economic shocks hinder poverty alleviation efforts, exacerbate inequalities, and often push vulnerable populations further into destitution. Food security, which involves access to sufficient, safe, and nutritious food, is heavily compromised by climate change. Agricultural productivity is highly sensitive to temperature fluctuations, precipitation patterns, and the frequency of extreme weather events. In countries like India, Bangladesh, and parts of Africa, erratic monsoons and rising temperatures have led to reduced crop yields, increased incidence of pests and plant diseases, and loss of arable land due to soil degradation and salinization. These changes heighten the risk of malnutrition, undernourishment, and food price volatility, disproportionately affecting the poor who spend a larger share of their
