The European Union has been involved in combating gender-based violence in the Democratic Republic of Congo (DRC) for some years. This violence represents a major issue in this country which has been destroyed by conflict. The social context of the DRC assigns a different role to men and women, a role characterized by a persistent inequality and iniquity in the perception, position and access to opportunities. After the assessment of combating gender-based violence (GBV) in DRC in 2011, followed by the formulation of an EU initiative in preparation of the launch of a pilot project on the same issue in 2012, AETS has again been given the opportunity to implement this initiative. The assignment consists of a quantitative and qualitative study on socio-economic and cultural factors, the situation of women and the relationships between men and women in three provinces of intervention (Kinshasa, Bandundu and Maniema). The main objective of this assignment is to update the preliminary logical framework with a baseline of indicators, which will be used to measure the progress and impact of the programme. To reach this objective, AETS will contract a local research centre: Ecole de Santé Publique (ESP) of Kinshasa. It will collect the quantitative and qualitative data by carrying out household surveys in the three provinces of intervention. These data will enable the establishment of the logframe indicators and the adaptation and finalisation of the VBG prevention programme strategies. The assignment will also identify the social norms linked to gender and evaluate the level of women’s autonomy in their choices with regard to the quality and security of their lives. Further to this, it will analyse the offer and demand for services of protection and justice. The efficiency and the coordination of the VBG prevention programmes and interventions at a local, provincial and national level will also be assessed alongside the project.
