Security can be measured at four different levels individual security, national security, regional security and global security, according to relevance of the situation and the subject. Global leaders are concerned about global security and in the same way regional leaders are concerned about regional security. National leaders are concerned about national security. Consequently most of the time individual security is compromised. Although all four levels of security are important, individual security is fundamental for ensuring the other three types of security.

This paper asserts that security is directly linked to climate change. Climate change will impact security at all levels, individual, national, regional and global security. In the context of Pakistan and for the purposes of this paper, two potential threat areas- water and agriculture-were examined.

Water availability variability and water related disasters would increase manifold as IPCC predicted and water availability will be impacted by variability in climate. In the short run glaciers will melt with more speed, which can lead to floods. In addition to that erratic rainfalls can also increase the incidence of floods in the near future. The flood in 2010 in Pakistan is quoted as a major example of floods caused by erratic rainfalls. The Glacial Lake Outburst Flood (GLOF) can also create severe problems, as Atta Abad Lake is another prominent example. Furthermore, the paper states that both floods and droughts will impact the productivity of agriculture and livestock. Productivity and production of the sector will decrease.

In the past, the security dimension was missing from all the assessments made by the government of Pakistan. Loss of livelihood opportunities, houses, basic services, food and so on inevitably lead to social unrest and even violence and can ignite riots and conflicts in the short term. This can eventually lead to severe controversy, especially due to migration and limited resources and subsequently can threaten national peace and security.

Concluding, the author recommends that the government should develop civil institutes to minimize the impact of disasters, create institutes to ensure food security despite the unpredictability of climate change, plan according for the future and take innovative steps to tackle climate change.
