WPD Nepal has been working on the control arms campaign to educate and create awareness about the illegal possession and trade of small arms and other portable lethal weapons, as well as the impacts of proliferation and misuse of small arms and light weapons on women and girls. WPD Nepal has been working to create awareness about illicit use and trade of small arms and weapons at the local, national and international level. Various national and international programs are conducted yearly for this approach. WPD Nepal lobbied with Parliament members, policy makers, social leaders, the Ministry of Foreign Affairs, the Ministry of Defense, and security sectors within the government in order to ratify the Arms Trade Treaty (ATT) and to prevent the illicit trade of arms.

WPD Nepal has worked closely with IANSA and the Control Arms Coalition in facilitating this campaign.
