Yet, none of the countries in South Asia have signed any major convention or treaty at the international level in regard to refugees; nor have they any national legislation or regional framework to deal with these issues. A comprehensive study focusing on the various dimensions of displacement in South Asia including refugees, migrants, stateless persons and Internally Displaced Persons (IDPs) was felt imperative by the Institute of Peace and Conflict Studies. Acknowledging non-traditional sources of insecurity as being the cornerstone of human insecurity, the IPCS had commenced to focus on a range of non-military threats to security including Drug Trafficking, Terrorism, Refugees, Organized Crime, Governance and Environmental Issues. The current volume with specific focus on migration and displacement is a small step in that direction.
