semantic and academic debates over terms, it is now widely acknowledged that environmental factors play both direct and indirect roles in both political disputes and violent conflicts. In the academic sphere environmental security is defined as the relationship between security concerns such as armed conflict and the natural environment. A small but rapidly developing field, it has become particularly relevant for those studying resource scarcity and conflict in the developing world. Prominent early researchers in the field include Felix Dodds, Norman Myers, Jessica Tuchman Mathews, Michael Renner, Richard Ullman, Arthur Westing, Michael Klare, Thomas Homer Dixon, Geoffrey Dabelko, Peter Gleick, Rita Floyd and Joseph Romm. Origins According to Jon Barnett, environmental security emerged as an important concept in security studies because of some interrelated developments which started in 1960s. The first one was the increasing level of environmental consciousness in so called developed countries. Various occurrences and events triggered the growth of the environmental movement during this period of time. Rachel Carson's well-known book Silent Spring was one of the extraordinary publications of that time and brought greater degree of environmental awareness among ordinary people by warning them of the dangers to all natural systems including animals and food chain from the misuse of chemical pesticides such as DDT. Whilst Carson undoubtedly contributed to public debate at the time she was arguably not amongst the more radical 'social revolutionaries' who were also urging greater public awareness of environmental issues. Moreover, a number of the largest well-known environmental non-governmental organizations such as the World Wildlife Fund (1961), Friends of the Earth (1969), and Greenpeace (1971) were founded during that time. Climate security is an extension of environmental security. The second notable development which brings the emergence of concept of environmental security was number of scholars started to criticize the traditional notion of security and mainstream security debates in their work from 1970s by emphasizing its inability to handle environmental problems at national and international security level. First commentators were Richard Falk who published 'This Endangered Planet' (1971), and Harold and Margaret Sprout who wrote 'Toward a Politics of Planet Earth' (1971). These two commentators asserted in their book that the notion of security can no longer be centered only on military power, rather nations should collectively take measurements against common environmental problems since they pose threat to national well-being and thus international stability.
