Part of a series of four entitled Urban Patterns for a Green Economy, this guide argues that strategic investment in physical infrastructure with the diversification of economies allows cities to play a specialized role in polycentric urban development.

Furthermore, it suggests that green economic development can be achieved through the development of green clusters and green jobs. Finally, this guide argues that a number of green economy outcomes may be reached through efficiencies and shared infrastructure, rather than duplication.

Part of a series of four entitled Urban Patterns for a Green Economy, this guide (Working with Nature) focuses on the effect of unplanned, rapid growth of cities on the functioning of a city-region's natural systems. It outlines how guided development can maximise the ability of ecosystems to support sustainable human and natural processes.

It offers a perspective on how to work with nature and the ecological processes in regions, and looks at the need to work across scales; to understand regional systems; and develop principles and measures that can be applied at the regional, city and local scales.

Part of a series of four entitled Urban Patterns for a Green Economy, this guide explores the compact city and its benefits within the developed and developing world's contexts. The guide illustrates how the compact city concept and planned (versus unplanned) urban extension can support sustainable urban patterns that benefit the functioning of developed as well as developing world cities.

Properly managed, compaction can positively enhance the life of the city dweller and support related strategies aimed at promoting a green economy and sustainable urban settlements.

Part of a series of four entitled Urban Patterns for a Green Economy, this guide proposes that cities can act as agents for change that allow their large populations to live less wastefully.

It considers how infrastructure systems can be viewed as an opportunity to shift cities onto a more sustainable path by paying close attention to the resources that pass through them, and the manner in which they support the activities of the city. Each city context differs, based on stage of development, pace of growth and available resources.
