Efforts to control small arms and light weapons (SALW) in the periods following violent conflict can have positive or negative impacts on peacebuilding efforts. Similarly, peacebuilding activities can both support or endanger efforts to place SALW under greater control. Despite the regular occurrence of SALW control and peacebuilding activities in the same time and space in post violent conflict contexts, there is insignificant analysis of how the two sets of activities interrelate, and how these interelationships can be strengthened to improve the contribution that SALW control efforts make to peacebuilding, and vice-versa. The effects of interrelationships over time (contingency); in the same geographic space (complementarity) and the effects of public perceptions and social construction are particularly important and provide a framework for establishing these interrelationships through analysing a wide universe of cases of SALW control attempted in countries emerging from violent conflict, five mini-cases studies and a major analysis of interrelationships in Kosovo.
