Between 2008 and 2014, ETH Studio Basel, under the guidance of Roger Diener and Marcel Meili, has been investigating the process of urbanisation taking place outside cities. Territory - in the context of this investigation denotes both: the surroundings that a city subsumes into its own structure and the core city itself, which is the centre of this process of urbanisation, or "confiscation". Investigated were six regions on six continents: The Nile Valley with the dense corset of natural landscape surrounding a linear city; Rome-Adria, where territorial cells have formed within the territory, spawning an urban type of tremendous dynamism; Florida, presenting highly complex patterns of territorial organisation; Vietnam's Red River Delta, where recent reform exposed traditional settlement and cultivation of the delta to freer forces; Oman, where urbanisation of a territory essentially means reclaiming the desert with the immediate necessity to develop a system for water distribution; and Belo Horizonte, where natural conditions likewise play a major role in organising the territory as surface mining entails huge transformations of the natural terrain. The new book features two introductory essays on ETH Studio Basel's research approach and on terminology, concise illustrated reports on the six regions, and four concluding topical essays.

A variety of air pollutants are emitted into the atmosphere from human-caused and natural emissions sources throughout the United States and elsewhere. These contaminants impact sensitive natural resources in wilderness, including the national parks. The system of national parks in the United States is among our greatest assets. This book provides a compilation and synthesis of current scientific understanding regarding the causes and effects of these pollutants within national park lands. It describes pollutant emissions, deposition, and exposures; it identifies the critical (tipping point) loads of pollutant deposition at which adverse impacts are manifested.
