Book excerpt: This book takes a broad look at conceptual and practical applications of gender budgeting in Europe. It comprises three linked sections that work through conceptual definitions of gender budget analysis. These sections explore how it can be framed and constructed as a gender equality policy; investigate case studies across Europe; and examine challenges for implementation. The first book of its kind, Gender Budgeting in Europe explores conceptual and methodological variations evidence in practice in Europe and the challenges of adoption and implementation in different political and institutional contexts. It brings together historical and current conceptual developments and tensions; approaches, methodologies, and tools in practice across Europe; activism, actors and agency and the engagement of formal institutions at all levels of government with feminist policy changes and feminist analysis and activists. This text is fascinating reading for students, scholars, policy makers and activists.
