Cities around the world are facing severe environmental challenges; many have high levels of air and soil pollution, overcrowding, poor sanitation and growing waste disposal problems. This book takes a positive attitude; cities can be made to work sustainably, and many are already doing so. Their high population density works in the environment's favour if they achieve efficient use of resources such as energy and water supplies, and improve transport and infrastructure. The best cities today are clean, resource efficient, green and pleasant, and act as cultural and entertainment centres as well as being efficient generators of economic activity.Making Cities Work looks at the vital role which local authorities can and are playing in safeguarding and developing our towns and cities. Their role is crucial, and the aim of this book is to make governments, international bodies, local authority associations and interested readers aware of how potential environmental and social problems can be overcome, and what can be achieved particularly through cooperation between local governments around the world. The second part of the book comprises 18 case studies from around the world which demonstrates how cities can learn from each other's best practice in urban sustainable development. Written by urban development experts, based on material supplied by the world's leading city associations and commissioned and commissioned by UNCHS for the Habitat II Conference, this is a crucial contribution to the urban debate. Clearly written, accessible and illustrated throughout with photographs, figures and graphs, it is ideal for students, fascinating reading for the general public, and essential for those involved in local authorities, planning and development.

For too long, cities have been thought of as environmental blackspots, with high levels of air and soil pollution, overcrowding, poor sanitation and growing waste disposal problems. This book takes a more positive attitude: cities can be made to work sustainably. Their high population density can work in the environment's favour if they can achieve efficient use of resources such as energy and water supplies, and improve transport and infrastructure. The best cities today are clean, resource efficient, green and pleasant, and not only act as cultural and entertainment centres, but also harbour great varieties of wildlife. Making Cities Work looks at the vital role which local authorities can - and must - play in safeguarding and developing our towns and cities. Their role is crucial, and the aim of the book is to make governments, international bodies and local authority associations aware of how potential environmental and social problems can be overcome, and what can be achieved. This book is being written by urban development experts, based on material supplied by the world's leading city associations. It is being edited by one of the world's most highly regarded cultural ecologists, and has been commissioned by UNHCS for the Habitat II conference. Clearly written, accessible, and fully illustrated throughout with photographs, figures and graphs, it is ideal for students, fascinating reading for the general public, and essential for those involved in local authorities, planning and development.
