Ecology of Cities: Managing Human-Nature Relationships in the City

Date: 17th September, Friday
Time: 4.00pm – 5.30pm SGT (GMT +8) 


Greenery pervades Singapore’s urban landscape today. As we move towards becoming a “City in Nature”, we will further integrate nature into our city to strengthen Singapore’s distinctiveness as a highly liveable city, while mitigating the impacts of urbanization and climate change.

In this last of three webinars on “City in Nature”, we will discuss how our urban society is increasingly interacting with the natural environment. This includes planning for greenery upstream in long-term city planning, learning to manage human-animal interactions, and exploring how nature can improve our well-being.

Harvey’s research focuses on critical urban studies, citizen urban science and policy-making as well as nature-society interactions. Previously an Associate Professor of Geography at the National University of Singapore, he has won multiple teaching and research excellence awards and taught courses on urban development, resource geography, environmental politics and nature/society issues. Harvey is an Associate Editor, Regional Studies, Regional Science (published by the Regional Studies Association and Taylor & Francis) and Member of the International Editorial Advisory Board, Geographies of Justice and Social Transformation Book Series (published by University of Georgia Press).

Amongst other things, he is interested in how a citizen-centric urban science can be practised, and sustained in tandem with “big data”, and in so doing, how it can influence urban policies positively. The future of such citizen urban science will be studied across several Southeast Asian cities, including Phnom Penh, Jakarta and Manila. Harvey is also developing a research programme on “urban sustainability” at the LKYCIC, focusing on the issues of water, food and energy.
