Greening Cities: Forms and Functions

This book offers an overview of recent scientific and professional literature on urban greening and urban ecology, focusing on diverse disciplines such as landscape architecture, geography, urban ecology, urban climatology, biodiversity conservation, urban governance, architecture and urban hydrology. It includes contributions in which academics, public policy experts and practitioners share their considerable knowledge on the multi-faceted aspects of greening cities. The greening of cities has witnessed a global resurgence over the past two decades and has made a significant contribution to urban liveability and sustainability, as well as increasing resilience. As urban greening efforts continue to expand, it is useful to promote recent advances in our understanding of various aspects of planning, design and management of urban greenery, but at the same time, it is also important to realize that there are important gaps in our knowledge and that further research is needed. The book is organized in three main parts: concepts, functions and forms of urban greening. The first part examines the historical roots of greening cities and how the burgeoning field of urban ecology can contribute useful principles and strategies to guide the planning, design and management of urban greening. The second part shifts the focus to the diverse range of services – the functions – provided by urban greening, such as those related to urban climate, urban biodiversity, human health, and community building. The final part explores conventional, often neglected, but important forms of urban greenery such as urban woodlands and urban farms, as well as relatively recent forms of urban greenery like those integrated with buildings and waterways. It offers a ready reference resource for researchers, practitioners and policy-makers to grasp the critical issues and trigger further studies and applications in the quest for high-performance green cities.

Professor Jim Chi Yung obtained his PhD in agricultural soil science from the University of Reading, UK. He then studied at the US Geological Survey in Golden (Colorado School of Mines) for a Certificate in Hydrology. He is the Chair Professor in Geography at the University of Hong Kong since 2000, and served in the past as Head of Department of Geography and Dean of Faculty of Arts. His research revolves around the core theme of nature-in-city, which encompasses urban ecology, urban forestry, urban greening, urban soil science, green roof, green wall (vertical greening), and urban nature conservation. Adopting an interdisciplinary approach with an emphasis on compact and south cities, he focuses geographically on Hong Kong and other Chinese cities. He has extended his research findings to promoting good policies and practices on urban greening in Hong Kong, including tree planting, green roof, green wall, and nature conservation under the shadow of urbanization.
