Since 1991, UN-Habitat has been implementing programmes addressing women’s empowerment and gender mainstreaming in its’ overall activities. This evaluation assesses what the Women and Habitat Programme (WHP) and the Gender Unit have achieved in these areas. The Evaluation also focuses on understanding the relevance of UN-Habitat partnership with organizations dealing with women and habitat issues. Information and views were gathered from UN-Habitat staff and documents, as well as key partners. In addition, selective case studies were carried out in Tanzania and Ecuador, to assess the effectiveness of WHP’s operational programmes. The evaluation report outlines the history, lessons learned, useful indicators for gender mainstreaming; and recommendations for strengthening gender mainstreaming in UN-Habitat’s future work.
