This Good Practice Guide seeks to contribute positively to the development of an effective and inclusive Irish National Action Plan (NAP) to implement UN Security Council Resolution (UNSCR) 1325 and related commitments on women, peace and security (1820, 1888 and 1889). It draws extensively on recommendations from previous research undertaken by the Joint Consortium on Gender Based Violence, set out in two key reports – Stepping Up Ireland’s Response to Women, Peace and Security (2008) and Women, Peace and Conflict: UN SCR Resolution 1325 (2009). In addition to providing background information on UNSCR 1325 and Ireland’s efforts to implement the resolution, the main purpose of the Guide is to signpost the eight essential steps to achieving an effective and inclusive National Action Plan. The final section also contains sample strategic objectives, actions, indicators and targets of the type that we can expect to find in a UNSCR 1325 National Action Plan produced to current international standards. The actual strategic objectives of the Irish National Action Plan should emerge from the kind of consultative process recommended in this Guide. The samples illustrate the form and level of specificity that Government commitments should take in a National Action Plan. As such they are points of departure for discussion in the formulation of proposed objectives rather than proposals per se.
