Climate, Pollution and Adaptation
Chapter 9: Achieving urban sustainability and implications for the urban water environment
The concept of urban sustainability has been pushed to the forefront of policy-making and politics as the world wakes up to the impacts of climate change and the effects of modern urban lifestyles. Climate change has emerged to be one of the greatest challenges faced by our planet today, threatening both built and natural systems with long-term consequences, which may be irreversible. Therefore, in order to be sustainable, there are drastic measures that need to be undertaken. Current single purpose and planning approaches that are open-looped are not sustainable. They can be too resource-intensive, consume too much energy and support the consumption of natural resources at a rate that will exhaust their supply. Consequently, it is vital that modern society, policy-makers, developers, engineers and planners become pioneers in introducing and incorporating sustainable features into urban and transport system development (Yigitcanlar, 2010a, 2010b). As discussed in the previous chapters, urban water environments along with other urban ecosystems are under constant threat due to the impacts of rapid urbanisation, excessive agricultural and industrial activities, and polluting transport systems using fossil fuels, along with the changing climate. In order to achieve a sustainable urban water environment, it is crucial to establish a sustainable urban form and transport system.
