Book excerpt: In a world where gender-based violence remains an alarming global issue, with statistics revealing high rates of physical and sexual violence against women, the need for effective intervention is paramount. Grounded in the multifaceted approach advocated by international expert groups, Comprehensive Sexuality Education for Gender-Based Violence Prevention strives to illuminate the vital relationship between comprehensive sexuality education and the prevention of gender-based violence among young people. This book delves into the critical aspects outlined in the Sustainable Development Goals (SDGs) by addressing the urgent call for expansive, multi-sectoral interventions. Drawing from a wealth of scientific literature, it emphasizes the importance of moving beyond the biological aspects of sexuality education to encompass emotional, social, and cultural elements. Through a multidisciplinary lens, this book explores how comprehensive sexuality education can serve as a powerful tool to combat gender-based violence, offering young people an understanding of sexuality, gender dynamics, and healthy relationships. The chapters examine the integration of inclusive curricula in schools, the pivotal role of families in sexuality education, and collaborative efforts between activists, schools, and education stakeholders. This comprehensive resource caters to a diverse audience, making it an indispensable tool for researchers seeking knowledge and inspiration for further inquiry, teachers enriching their educational programs, and health professionals to understand the intersection of education, sexuality, and violence.
