There has been much scholarly debate on the politically disruptive capabilities of Islam and the threats to global security posed by or to Muslim states and societies, but within this dialogue there has been little recognition of the role of population policies in security issues. Katrina Riddell's study focuses specifically on Islam and the securitization of population policies and sustainability. Opening with a discussion of contemporary population discourses and their historical foundations, the book examines how population growth has become an international security issue. The author takes the examples of Pakistan and Iran to provide a nuanced understanding of Muslim states' interaction with global debates on sustainability. She also explores how Muslim and non-Muslim states, societies and agents perceive issues of population growth and control. Providing an innovative approach to the pursuit of global sustainability and security, this book presents useful material to scholars whose research focuses on Islam and the future.
