This 3-part Masterclass includes a rapid review of what’s known about urban heat islands, and provide insights into considerations for choosing interventions to manage them.
Participants learned about the Urban Heat Island effect Tool tip The UHI effect is caused by cities replacing the heat buffering ecosystem services afforded by soil and vegetative evapotranspiration with heat-absorbing materials, wind-blocking & radiation trapping structures, and waste-heat from air conditioning, automobiles, and other sources. In some cases, this effect can drive temperature differentials of 10 degrees Celsius – from the urban core to the exurban periphery, but also within urban areas from neighbourhood to neighbourhood. – what causes it, how we map and model it, and what we can do about it.
This masterclass series is complementary to the NASA ARSET Training: Satellite Remote Sensing for Urban Heat Islands, which ran in November 2020, and for which course materials are available online.
Target Audiences: Interested experts may include urban planners, designers, architects, sustainability/resilience officers, city government officials, urban climate scientists and other researchers.

I’m Director of Commercial and Expansion at Edge, leading our work to grow our service offering in the Asia Pacific region. I was a co-founder of Seed Consulting Services which merged with Edge in 2019 and I am also a Director of agricultural and NRM data acquisition and analytics firm AirborneLogic. I have a Bachelor’s Degree in Science with Honours and a PhD in Environmental Science from the University of Adelaide. I have held various roles on non-profit Boards and Committees and I’m a graduate of the Australian Rural Leadership Foundation’s Murray-Darling Basin Leadership Program. My interest in sustainability took off at a young age, influenced by reading David Suzuki’s various books, growing up on a small farm in the Adelaide Hills and spending time camping on the River Murray. My specialties are in climate change risk assessment and planning, liveable cities, strategic planning and stakeholder engagement. I have experience from a broad range of sectors including state and local government, agriculture, health, energy and My favourite projects are the ones that bring together technical, planning and engagement work to address complex sustainability challenges like tackling climate change and creating cool cities. I enjoy being part of having the “hard discussions” that often need to occur to drive sustainability forward in both the corporate and community spheres. In previous roles I worked as the Operations Manager for a water trading firm and also held several roles at the Murray-Darling Basin Authority related to environmental water management and delivery. When I’m not working I enjoy spending time with my wife and three children, which tends to involve running around at various weekend sporting events. If I’m lucky I might even get in a run, spot of fishing or catch a game of AFL!Read More

Dr. Vivek Shandas specializes in developing strategies for addressing the implications of climate change on cities. His teaching and research examine the intersection of exposure to climate-induced events, governance processes, and planning mechanisms. As an interdisciplinary scholar, Dr. Shandas studies the emergent characteristics that generate vulnerability among communities and infrastructure. Theoretically, he views cities as grand experiments that are socially constructed, and can vary in their capacities to adapt to changing social and ecological conditions. Empirically, Dr. Shandas examines the human and planetary forces that facilitate (or inhibit) collective response. As such the broad aims of his teaching and research are to identify threats to planetary habitation, and shape landscapes to improve urban environmental quality.Read More
