STOCKHOLM, Oct. 30(Greenpost) –Australian Xuemei Bai has won 2018 Volvo Environment Prize, announced Volvo Environment Prize Foundation on Tuesday in Stockholm.

“Sustainability will be won or lost in cities”

Professor Xuemei Bai, a leading expert and thought leader on urbanization and sustainability, receives the Volvo Environment Prize 2018. More than half of the world’s population lives in cities, and the trend keeps growing at an unprecedented rate. In future we will need drastically different ways of planning, building and governing cities, says Xuemei Bai.

Cities have been the cradles and powerhouses of new ideas and movements from time immemorial. They still are – from the industrial revolution in Birmingham in the 18th century to the breakneck speed of economic growth in Bangalore, India, today.

The lure of a better life attracts millions of people to the cities of the world. For the first time in history more people are living in cities than in rural areas. And this way of living is set to continue: by 2050 more than two thirds of the world population will live in urban areas.

– Urbanization is arguably one of the biggest social transformations of our time says Xuemei Bai, professor in Urban Environment and Human Ecology at the Fenner School of Environment and Society at the Australian National University in Canberra.

Born and raised in China, living in Japan for many years and now an Australian citizen, she is a leading expert on how to make rapidly growing cities more liveable, sustainable and resilient. Her focus is on Asia and the global South. For while cities in the North try – and sometimes succeed – in becoming smart, green and carbon-neutral, cities such as Lagos, Nigeria, have grown 100-fold and are environmental nightmares. In just two generations, Lagos went from a population of 200,000 to nearly 20 million. It is wealthy in parts, but largely chaotic and with many residents living in slums not connected to water or sanitation systems, and with momentous traffic congestion and air full of fumes. Projections show that if Nigeria’s population continues to grow, Lagos could become the world’s largest metropolis, home to perhaps 85 million people, with drastic environmental consequences.

But other megacities are growing at an even faster rate, such as Guangzhou and Beijing in China and Kinshasa in Democratic Republic of the Congo. In fact all of the top 10 fastest growing megacities are in Asia or Africa. Says Xuemei Bai:

– It is sometimes said that sustainability will be won or lost in cities. I would go one step further and say that sustainability will be won or lost in cities in the Global South.

Nowhere in the world has the scale and speed of urbanization been more overwhelming than in China, with possibly the fastest and largest migration of a human population in history. In just 30 years, nearly 500 million people have moved from rural areas into China’s major cities. This is how China grew its economy at a stunning pace, but it has also resulted in polluted air and contaminated rivers and soil. The Chinese authorities are trying to rectify some of the mistakes but the task will probably take generations.

At the core of Xuemei Bai’s research is how to do the right things when new urban areas are built. Cities have a huge impact, with about 75 % of CO2-emissions from energy use traceable back to cities. Making cities sustainable will mean aiming for processes similar to those in natural ecosystems, reducing input and output and making material and energy use more circular.

– We need to approach cities as a human-dominant complex ecosystem and manage them as such. If we do that I believe there is a bright future for humans and their cities.

 Cities play a critical role in both causing and potentially solving many of today’s sustainability challenges. Professor Xuemei Bai is one of the most active global thought leaders in urban sustainability research, working across scales and tackling both theoretical and applied challenges with a focus on urban development in East Asia. Her pioneering inter- and trans-disciplinary research focuses on understanding the complexity of the social, ecological and economic drivers and impacts of urbanization, and the science and policy of urban sustainability transitions. She and co-authors introduced the concept of urban sustainability experiments – novel practices with significant potential to change the status quo. Most of Professor Bai’s research has clear policy implications, spanning from identifying and testing local solutions to addressing broader national and global policy challenges. Direct impacts of her research include the proliferation of solar energy use in Rizhao City, as well as the development of sustainable urbanization strategies in the western region of China and the regeneration of forests using native tree species at mining sites in Japan. She has contributed to regional and international science initiatives including the Millennium Ecosystem Assessment, IPCC and Future Earth, in particular leading the development of the Urban-Knowledge Action Network.

Professor Bai’s work is an outstanding example of the application of research to policy and practice. She is a most deserving recipient of the Volvo Environment Prize in 2018.
