The Small Arms Survey is an independent research project located at the Graduate Institute of International and Development Studies in Geneva, Switzerland. It serves as the principal source of public information on all aspects of small arms and armed violence and as a resource centre for governments, policy-makers, researchers, and activists. The Small Arms Survey 2009 contains two thematic sections. The first highlights the challenges of ensuring security after the formal end of war and comprises an overview chapter and three case studies (Aceh, Afghanistan, and Southern Lebanon). The second thematic section explores various aspects of small arms transfers, including the value of the authorized trade, national controls, and weapons tracing. Additional chapters focus on small arms measures and impacts.
