Book excerpt: Regions of the world with greatest biodiversity are shown to exhibit greatest linguistic diversity, strongly suggesting that the relationship between language and ecology is both symbiotic and spatially and temporally determined. This volume examines the expressions of, and threats and challenges to, this relationship in southern and eastern Arabia. Exploring the ways in which indigenous languages reflect the close relationship between people and their natural environment, this book presents an overview of the key threats and challenges, and introduces the methodologies used to investigate them. Across the chapters, case studies are presented dealing with language, gesture and ecology, the significance of naming, the role of narratives in the language–ecology relationship, and conservation and revitalisation of bio-cultural diversity in Arabia. Taking a multidisciplinary view, this book argues for the central role that language plays in facing the challenges and threats to bio-cultural diversity, and presents methods for the study of the language–nature relationship that can be applied globally.
