This groundbreaking and accessible book engages vexed and vexing questions about the future of the Women, Peace and Security agenda, balancing analysis of emerging trends with reflections from those at the forefront of policy and practice. What does gender equality mean for peace, justice, and security? At the turn of the 21st century, feminist advocates persuaded the United Nations Security Council to adopt a resolution that drew attention to this question at the highest levels of international policy deliberations. Today the Women, Peace and Security agenda is a complex field, relevant to every conceivable dimension of war and peace. This groundbreaking book engages vexed and vexing questions about the future of the agenda, from the legacies of coloniality to the prospects of international law, and from the implications of the global arms trade to the impact of climate change. It balances analysis of emerging trends with specially commissioned reflections from those at the forefront of policy and practice.
