This set of ten papers brings together lessons and experience on women's leadership and participation from Oxfam GB and its partners. The right to participate in decision-making at the local, national, and international level is one which women are often denied, whether as active citizens or as leaders. In particular, women living in poverty often have very little opportunity to influence decisions and policies that will have a direct influence on their lives and livelihoods, and on the welfare of themselves and their communities. Engaging more women to participate in decision-making will ensure that their perspectives and needs are more likely to be reflected, as these case studies illustrate. The case studies illustrate methodological approaches and learning points. They cover a range of issues, from women's participation in national elections to female decision-making in community livelihood initiatives. Authors highlight three main approaches to strengthening women's leadership and participation: Overcoming structural barriers to women's leadership and participation Supporting women to take up leadership positions Encouraging and supporting women (and men) to carry out leadership roles effectively and for progressive purposes.
