Urban land is an environmental key topic considering the increasing urbani sation of our world. The amounting pressure on resources especially in the urban environment demand awareness across technical and political sectors and solid concepts for workable solutions. This book will address those people, who are key in coping with the challenges of sustainable urban land use management: Professionals in the growing field of urban land recycling and graduate students from different disciplines including urban planning, environmental sciences and geotechnics. Processes that lead to urban land degradation include the extraction of resources, their transformation into goods, the production of waste and conflicts in the allocation of land. Industrial soil pollution, soil sealing and urban sprawl pose serious challenges to resource management in urban environments. The possible implications are not necessarily restricted to the urban area but do have feedback into the countryside. The reduction of arable land in urban peripheries often causes enhanced pressure on back-country natural ecosystems such as forests, grass- and wetlands. Urban land recycling especially in the developing world is to be seen in the context of poverty alleviation and sustainable development. Ifwe don't get a proper sustainable use of urban land, as well as of water and other natural resources that relate to them, sustainable development will not be reached.

This book provides a comprehensive overview of remediation and rehabilitation techniques and strategies for contaminated and anthropogenically disturbed land. Rehabilitation approaches in the urban environment, such as brownfield redevelopment and urban mining, are discussed. In relation to contaminated land, techniques for soil containment and decontamination of soil, soil vapour and groundwater are comprehensively and systematically presented. Complicated treatment techniques are schematically depicted and can be readily understood. Agricultural, silvicultural and environmentally sustainable rehabilitation strategies for reclaiming disturbed land/terrain in former mining or natural-resource extraction areas, such as open-cast mines, quarries, harvested peatlands, and subsided mining terrain (sinkholes), are introduced. This book will be a useful tool for students, researchers, private consultants and public authorities engaged in the treatment of contaminated or disturbed land.

The birds, animals, insects, trees and plants encountered by the majority of the world’s people are those that survive in, adapt to, or are introduced to, urban areas. Some of these organisms give great pleasure; others invade, colonise and occupy neglected and hidden areas such as derelict land and sewers. Urban areas have a high biodiversity and nature within cities provides many ecosystem services including cooling the urban area, reducing urban flood risk, filtering pollutants, supplying food, and providing accessible recreation. Yet, protecting urban nature faces competition from other urban land uses. The Handbook of Urban Ecology analyses this biodiversity and complexity and provides the science to guide policy and management to make cities more attractive, more enjoyable, and better for our own health and that of the planet. This Handbook contains 50 interdisciplinary contributions from leading academics and practitioners from across the world to provide an in-depth coverage of the main elements of practical urban ecology. It is divided into six parts, dealing with the philosophies, concepts and history of urban ecology; followed by consideration of the biophysical character of the urban environment and the diverse habitats found within it. It then examines human relationships with urban nature, the health, economic and environmental benefits of urban ecology before discussing the methods used in urban ecology and ways of putting the science into practice. The Handbook offers a state-of the art guide to the science, practice and value of urban ecology. The engaging contributions provide students and practitioners with the wealth of interdisciplinary information needed to manage the biota and green landscapes in urban areas.

With more than 50% of the world’s population already living in towns and cities, migration from rural areas continuing at an alarming rate in developing countries and suburbanisation using more and more land in developed countries, the urban environment has become supremely important with regard to human health and wellbeing. For centuries, urbanisation has caused relatively low level soil conta- nation mainly by various wastes. However, from the time of the Industrial Revolution onwards, both the scale of urban development and the degree of soil contamination rapidly increased and involved an ever widening spectrum of c- taminants. With constraints on the supply of land for new urban development in many countries, it is becoming increasingly necessary to re-use previously dev- oped (brownfield) sites and to deal with their accompanying suites of contaminants. It is therefore essential to fully understand the diversity and properties of urban soils, to assess the possible risks from the contaminants they contain and devise ways of cleaning up sites and/or minimizing hazards. The author, Helmut Meuser, is Professor of Soil Protection and Soil Clean-up at the University of Applied Sciences, Osnabrück and is one of Europe’s foremost experts on contamination from technogenic materials in urban soils. He has many years’ experience of research in Berlin, Essen, Osnabrück, other regions of Germany, and several other countries.

Every engineering structure, whether it's a building, bridge or road, is affected by the ground on which it is built. Geology is of fundamental importance when deciding on the location and design of all engineering works, and it is essential that engineers have a basic knowledge of the subject. Engineering Geology introduces the fundamentals of the discipline and ensures that engineers have a clear understanding of the processes at work, and how they will impact on what is to be built. Core areas such as stratigraphy, rock types, structures and geological processes are explained, and put in context. The basics of soil mechanics and the links between groundwater conditions and underlying geology are introduced. As well as the theoretical knowledge necessary, Professor Bell introduces the techniques that engineers will need to learn about and understand the geological conditions in which they intend to build. Site investigation techniques are detailed, and the risks and risk avoidance methods for dealing with different conditions are explained. * Accessible introduction to geology for engineers * Key points illustrated with diagrams and photographs * Teaches the impact of geology on the planning and design of structures
