Smart Green Resilient (SGR) is a new planning approach developed by Arup and is based on over a decade of observations and multi-faceted participation in East Asia’s urban growth. The three-in-one thinking provides an overarching conceptual framework to enhance the urban planning process and concurrently respond to today’s environmental, economic and social challenges. More importantly it provides a cognitive prism to reveal how the myriad tangible and intangible elements that drive the growth of urban settlements, can be negotiated to generate holistic outcomes. The book details how the SGR concept has evolved against the background of growing environmental awareness and the different ways cities and planners have responded to these escalating challenges over the recent years. Through a number of high profile projects across Asia, from the Ninh Thuan Integrated Planning Strategy in Vietnam to planning studies for Hong Kong’s Lok Ma Chau Loop and Taiwan’s Taoyuan Aerotropolis, the book outlines some of the main elements that characterise the SGR approach, implementation in projects and sources of inspiration from global geographies. The approach has been adopted by the Hong Kong government’s Planning Department as the city’s ‘new planning vision’.
