L'Arctique suscite aujourd'hui une attention particulière. Avec le réchauffement climatique, ses ressources fossiles deviennent plus accessibles, ce qui attise la convoitise de toutes les grandes puissances. Or du fait d'une géographie physique variée, et de la présence de quatre millions d'habitants qui sont les premiers concernés, l'Arctique est un espace complexe. Dans ce livre, Klaus Dodds et Jamie Woodward examinent successivement l'environnement physique, les écosystèmes, la présence humaine, l'exploitation des ressources et la gouvernance de ce vaste territoire. Ils décrivent les causes, les moteurs et les effets des changements culturels, environnementaux, géopolitiques et économiques, et finalement s'interrogent sur le devenir de l'Arctique… et ses possibles conséquences à l'échelle de notre planète.

This volume explores the climates, landscapes, ecosystems and hazards that comprise the Mediterranean world. It traces the development of the Mediterranean landscape over very long timescales and examines modern processes and key environmental issues in a wide range of settings. The Mediterranean is the only region on Earth where three continents meet and this interaction has produced a very distinctive Physical Geography. This book examines the landscapes and processes at the margins of these continents and the distinctive marine environment between them. Catastrophic earthquakes, explosive volcanic eruptions and devastating storms and floods are intimately bound up within the history and mythology of the Mediterranean world. This is a key region for the study of natural hazards because it offers unrivalled access to long records of hazard occurrence and impact through documentary, archaeological and geological archives. The Mediterranean is also a biodiversity hotspot; it has been a meeting place for plants, animals and humans from three continents throughout much of its history. The Quaternary records of these interactions are more varied and better preserved than in any other part of the world. These records have provided important new insights into the tempo of climate, landscape and ecosystem change in the Mediterranean region and beyond. The region is unique because of the very early and widespread impact of humans in landscape and ecosystem change - and the richness of the archaeological and geological archives that chronicle this impact. This book examines this history and these interactions and places current environmental issues in long term context.
