Climate change has emerged as one of the most pressing challenges to human existence, exerting profound effects not only on ecosystems and natural processes but also on the social, economic, and political fabric of societies. The concept of human security, developed in contrast to state-centric notions of security, emphasizes the protection of individuals and communities from threats to their survival, livelihood, and dignity. The United Nations Development Programme (UNDP) identifies seven dimensions of human security: economic, food, health, environmental, personal, community, and political security. Each of these is being reshaped by the complex and intensifying effects of climate change, with developing countries facing the most severe consequences due to limited adaptive capacity, high levels of poverty, and socio-political vulnerabilities. Examining the impacts of climate change on these seven dimensions provides a holistic understanding of the human implications of global warming. Economic security is increasingly jeopardized by climate change. Developing countries, many of which rely heavily on climate-sensitive sectors such as agriculture, fisheries, and tourism, are particularly vulnerable. Rising temperatures, changing precipitation patterns, and increasing frequency of droughts and floods undermine agricultural productivity, leading to reduced income for millions of farmers. For instance, in sub-Saharan Africa and South Asia, smallholder farmers often lack irrigation infrastructure, insurance mechanisms, or access to financial resources, leaving them exposed to crop failure. Coastal economies in Southeast Asia that depend on fisheries are threatened by ocean warming and acidification, which reduce fish stocks and disrupt livelihoods. Tourism-dependent nations such as the Maldives face risks from coral bleaching and sea-level rise, threatening both employment and national revenue. Climate-induced disasters also destroy infrastructure, disrupt supply chains, and burden governments with reconstruction costs. As economies contract and job opportunities decline, vulnerable populations experience deeper poverty, widening inequality, and social unrest. Food security is directly linked to climate change as it affects food availability, accessibility, utilization, and stability. Erratic rainfall and prolonged droughts reduce crop yields, while floods and storms damage stored grains and agricultural lands. For example, South Asia has witnessed repeated climate-induced flooding events that devastate rice __________ _________ ________ _________ ___ __________ ______.
