This report focuses on selected international security areas. At the theoretical level, it discusses new approaches to security dominated by multiplicity and complexity, with a special emphasis on three emerging concepts that have been increasingly used in security studies: globalization, human security and securitization. At the empirical level, it first looks at the a number of new security challenges, namely terrorism, health pandemics, international migration, environmental security, and energy security; assesses the impact of these challenges on the broader international security system; and examines the response these challenges have been given. Second, the report considers the changes to the international security system brought about by the rise of the BRICS. Third, it explores the changing nature of war, with an emphasis on the rise in civil wars, their relation to limited statehood and the role of external actors. Overall, the report presents an overarching analysis of developments in international security that will shape the way the subject is understood and approached in coming years.
