This book offers a profound examination of how mountain ethnic groups and local communities, particularly those in the Tibetan regions of the Eastern Himalayas, utilize traditional knowledge to confront the growing challenges of climate change. It presents a comprehensive analysis of the ways in which local wisdom--passed down through generations--has informed climate adaptation strategies, ranging from agriculture to disaster management. By systematically categorizing traditional knowledge related to climate patterns, biodiversity, water management, and resource conservation, the book highlights its vital role in enhancing resilience to environmental stresses. Drawing from field research, the volume addresses the intersection of modern climate science and traditional knowledge, advocating for an integrative approach to climate adaptation. The author demonstrates that traditional knowledge systems, far from being relics of the past, are dynamic and continually evolving to meet new environmental realities. This work provides a valuable theoretical framework and methodological tools for future research, calling for greater recognition of the potential contributions of traditional knowledge in global climate policy and local-level interventions. By illustrating the enduring relevance of traditional knowledge, this book not only contributes to the academic discourse on climate change but also advocates for the preservation and application of ecological wisdom in creating sustainable climate solutions for the future.
