Abstract

Problem statement: Climate change is increasingly one of the most serious national security threats which will have significant impacts on natural and coastal resources, ecosystem, human health and settlements, thereby affecting human wellbeing. At the same time, it is likely to influence of large scale human migration, economic and social depression over scarce natural resources and political systems necessary involve an even higher degree of uncertainty. Crucial for action is addressing climate change threats to small island states and states that are least developed, as environmental destabilization may lead to a major economic, environmental and political crisis that may not just affect these states but the world as a whole. Approach: Literatures were identified for review through a comprehensive search by using electronic and non-electronic databases. Related published literature and documents were searched in a systematic way using a range of key words relating to climate change impacts and national security. Results: The literature review indicates that climate change undermine national security dimensions by increasing environmental degradation, resources scarcity, large scale human migration as well as damage of infrastructure. The review also indicate that climate change undermine environmental dimensions by increasing sea level rise, extreme weather events, freshwater scarcity, land degradation and pollution; undermine economic dimensions by reducing access to and the quality of natural resources and human health, in addition to undermine of political dimensions with the possibility of increased environmental refugees, severe storms and failed economics. Conclusion: Reducing climate-induced threats that contributes to national security, there will need to develop an integrated approach in local and national levels and implement sustainable adaptive strategies as well as climate security.
