Abstract: Traditionally, security is equated with national security, which has been seen as a matter of the military defense of states’ geographical borders and a process of ensuring unity and integrity of a country. Security is no longer narrowly defined as military security. In the era of globalization, the contemporary society is not confronted with a single tangible threat, but a variety of challenges, which are more intangible and complex. Environmental problems, particularly climate change emerged as an important source of non-military threat along with others. Among various regions, Africa is considered as the most vulnerable region in the world in terms of climate change, because of its physical and socio-economic characteristics and its extreme climatic conditions. Though the climate change has various security implications, this paper analyzes few important aspects related to food security, desertification and migration and explains the link between the concept of security governance and the climate change in non-military perspective in African context.
