Environmental challenges require diverse legal approaches. In this comprehensive handbook, global scholars examine the nexus of Islam and environmental law as a significant yet understudied framework for contemporary governance. Spanning fourteen centuries of legal development, Islamic environmental jurisprudence offers sophisticated approaches to stewardship, resource management, and climate policy. Chapters include detailed case studies of Pakistan's constitutional courts and Malaysia's environmental legislation, Gulf economic transitions, and water-governance innovations, all demonstrating how Islamic legal principles inform real-world environmental solutions. Each contribution provides a nuanced analysis of how traditional concepts adapt to contemporary contexts across diverse Muslim-majority nations. Timely and innovative, this handbook is an ideal resource for environmental law scholars, comparative legal researchers, policy analysts, and development practitioners working in multicultural contexts.
