Environmental Security in Greece establishes stakeholders' perceptions of environmental security and energy security taking a Q-methodology and Digital Media Research Framework approach. In-depth individual viewpoints and opinions of policymakers, energy-industry leaders, NGOs' members and the public are described throughout. The book demonstrates the value of applying Q-methodology in the study of climate change as a security issue in a vulnerable country like Greece which represents a range of countries with many interrelated economic, societal, political and security problems. The research was conducted during the period from August 2007-2016 prior to the Paris Climate Agreement. Q-methodology systematically reveals the traditional and non-traditional security approaches and theories and compares academic and public perceptions. The methodology provides a means of investigating human subjectivity not hitherto used to investigate climate change and security issues. The author establishes a number of discourse factors shifting the discussion from traditional security and climate change scepticism to ecological security and protection.
