Most countries do not know much about the outcomes or impact of activities related to gender based violence. Gender based violence undermines both social and economic development and the individual’s capacity for realising her or his rights and potentials under already strained conditions. Statistical data in the Seychelles points to the growing phenomenon of gender based violence. It is therefore very important for a country to know the numbers reached by activities, the geographic coverage, impact and actual costs related to the activities for gender based violence, through the development of a plan of action. An action plan defines goals, activities, expected outcomes, responsible institutions, planned and required resources per year and the period for achievement of each goal. The action plan is therefore the foundation for defining the costing analysis. [...] In 2008, the Seychelles developed a National Strategy for Domestic Violence. For 2008 and 2009, GBV activities continued to be implemented albeit in the absence of a National Costed Action Plan. It became apparent that more conscious implementation of the strategy was only feasible if the country developed a costed action plan, which would be used as a tool for the implementation of the National Strategy. In early 2010 February and March, with the support of UNIFEM Southern Africa, Seychelles worked on the development of both a Two Year Action Plan and a Costed Two year Action Plan. This costed Two Year Indicative Plan is the outcome of work towards costing what it would cost the Seychelles to implement the activities in GBV over a period of two years (2010 and 2011).
