First published in 1981. Urban modelling techniques are an established tool in assessing the possible repercussions of major changes in land use. This book is an introductory guide to the various models that have been developed and to how they can be applied in planning practice, particularly with relation to land use activities such as residential, industrial and retail development, and changes in the transport network. The author has provided a coherent and reliable introductory text which will be welcomed by students and teachers in search of a guide to current methods in the field of urban modelling.

Britain's great cloak of natural forest disappeared mostly in prehistoric times. Over the passage of time and by the industrial revolution, Britain's economy had become almost entirely dependent on timber imports from abroad. Shipping blockades in the First World War meant a frantic search for woodlands that could be cut down to make vital pit props and sawn wood for wartime construction. After the war, Britain's tree cover was near to an all-time low. Only since 1919 have practical measures been taken to reverse the long history of forest decline, and a hundred years of tree planting has seen the forest cover of Britain more than double. Today, tree planting in Britain is motivated more by environmental and social concerns than purely timber production. In Woods and People, David Foot reveals the story of twentieth-century forest creation, and the eureka moment in the 1980s that challenged foresters and conservationists to work together on new ideas.

The journals of Dr. Wendell Wellington Wiggins might just be the most extraordinary contribution to the study of the earth's past since the discovery of the Rosetta Stone. In the incredible pages of these thought-to-be-lost diaries, Dr. Wiggins--whom we now must consider the greatest paleozoologist of all time--has divulged the secrets of the truly ancient animal world: a world before human beings; a world before dinosaurs; a world that, until now, existed well beyond the outer reaches of human imagination. From deadly Amazonian Whispering Vines (Vitus Sussurus) to curious creatures called Brittle Bones (Futilis Ossis) to a mysterious pet named Gibear (Chiroptera Vicugna Pacosis), the discoveries of Dr. Wiggins will forever change the way we think about the world before us.

In his examination of the bishopric of Orvieto from 1100 to 1250, David Foote reveals how three defining developments of the High Middle Ages-the feudal revolution, ecclesiastical reform, and state building-played out in a typical medieval Italian commune. He challenges scholarship that overemphasizes the secular nature of Italian city-states by showing the extent to which developments in ecclesiastical institutions provided a model for the formation of civic institutions and defined a commune's political and religious culture. Following the collapse of Carolingian authority in the tenth century, Italy experienced a period of political chaos. Rural lords, unrestrained by central authority, fought to dominate the countryside. Bishoprics, by virtue of their temporal and spiritual authority over dioceses, emerged in the midst of this disorder as the most effective institutions for rebuilding political authority at the local level. The Orvietan bishopric formed the center of an urban coalition attempting to conquer and pacify their contado, or surrounding countryside. Orvieto's bishopric assisted the early city-state in administering its territory by developing innovative methods of written administration and record keeping. As the center of a wide range of religious interests, the bishopric was often caught between competing political and religious actors who leveraged their interests through ecclesiastical institutions and resources. This interaction had a profound effect on the city's political and religious culture. As Orvietans struggled to define the norms that would govern their society, they had to adapt their quest for political power and autonomy to their religious values. David Foote's deeply researched new book illuminates the process of state building in its early stages and the formation of political and religious culture in Europe during the High Middle Ages.
