Although there is a breadth of literature and research on gender and armed conflict, its scope in the field of conflict resolution seems to be smaller than in other disciplines. Thus, the purpose of this research is to contribute to the existing literature on gender and armed conflict in the field of conflict resolution. My research looks at the changes that have occurred in United Nations peacekeeping since the adoption of Security Council Resolution 1325 in 2000, using secondary data to gain insight into seven selected peacekeeping missions. The focus is on women?s involvement in peacekeeping missions in uniformed components (military and police) and in the implementation of gender mainstreaming strategies and activities. Data were retrieved from publicly available secondary documents, including disaggregated data on uniformed peacekeeping personnel, and progress reports on gender mainstreaming in different missions. The findings showed that some improvements in gender inclusion and gender mainstreaming have occurred since the implementation of SCR 1325, however, these changes have been minimal. My findings not only reflect a number of the concerns raised in the existing literature, but they also seem to imply that change may not occur until there are changes in the social and cultural attitudes towards gender equality, both in missions? host countries as well as within the UN peacekeeping system.
