ANDERsON SERA NCAAM ANDERSON SERANGOON JUNIOR COLLEGE H1 GEOGRAPHY THEME 2 -URBAN CHANGE TOPIK 2.1 SusTAINABLE URBAN DEVELOPMENT I Os MANAGEMENT OF TRAFFIC CONGESTION Key Question: How does the demand placed on natural environments by urban areas influence progress towards sustainable development? 1. Introduction m Te previous lecture, we discussed urban population trends and how the high urbanisation rates and rapid urban growth pose serious challenges to sustainable urban development. Specifically, high urbanisation rates and urban growth is a key driver of resource consumption and Waste generation, which then leads to environmental issues that become a challenge to sustainable urban development: City-based production currently accounts for the majority of resource consumption and waste generation worldwide. Cities consume more than two-thirds of global energy and produce over 70 percent of carbon emissions (World Bank, 2010). Cities alsO present a number of environmental problems associated with the demands they place on ecosystems, resources and sinks of the surrounding region. In this lecture, we explore how the demands placed on natural environments by urban areas influence progress towards sustainable development. 1.1 Urban Metabolism and Sustainable Urban Development as: The concept of urban metabolism stems from the idea that cities are similar to organisms, as they both consume resources from their surroundings and excrete waste
