A number of studies and research findings have shown that abrupt climate change is capable of inducing negative impacts in socio-economic development in the global economy especially in developing countries like Nigeria. With estimated 400 million people living in the sub tropical over-populated regions today (IPCC), climate change and its effects pose severe risk to political, economic and social stability of Nations within the region. Scientific predictions for Nigeria indicate possible loss of settlements, agricultural lands and infrastructure installations due to extreme weather events such as drought and desertification in the northern zone, floods in the coastal and reverie zone, as well as erosion in eastern zone and other parts of the country. Violence and disruption stemming from stresses created by extreme weather events may pose different types of challenges to national security, the most outstanding being food shortages, decreases in availability and quality of fresh water and disruption of access to strategic mineral locations.
