smart, green and carbon-neutral<\/strong>, cities such as Lagos, Nigeria, have grown 100-fold and are environmental nightmares.<\/p>\nhttps:\/\/www.youtube.com\/watch?time_continue=85&v=jV3PxohRi28&feature=emb_logo<\/p>\n
A focus on the global South<\/h3>\n 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\u2019s population continues to grow, Lagos could become the world\u2019s largest metropolis, home to perhaps 85 million people, with drastic environmental consequences.<\/p>\n
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.<\/p>\n
Xuemei Bai. Sustainability in cities will be won or lost<\/h3>\n Says Xuemei Bai:\u00a0\u201cIt is sometimes said that sustainability will be won or lost in cities<\/strong>. I would go one step further and say that sustainability will be won or lost in cities in the Global South\u201d.\u00a0Nowhere 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\u2019s major cities.\u00a0This 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.<\/p>\n75% of CO2 emissions come from the cities<\/h3>\n At the core of Xuemei Bai\u2019s 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<\/strong>. Making cities sustainable will mean aiming for processes similar to those in natural ecosystems<\/strong>, reducing input and output and making material and energy use more circular<\/strong>.\u00a0\u201cWe 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\u201d.<\/p>\nThe motivation for the prize to Xuemei Bai<\/h2>\n The motivation of the jury of the Volvo Environment Prize Foundation:\u00a0\u201cProfessor 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 work is an outstanding example of the application of research to policy and practice.\u201d\u00a0This is echoed by the Vice Chancellor of the Australian National University, Professor Brian Schmidt, a Nobel Prize laureate in Physics:\u00a0\u201cXuemei Bai is an excellent researcher, well in front of the times. Her work here in Asia is absolutely poignant to the problems of the day. Study of urbanization and making that sustainable is something that is very real today and it is almost certainly going to be established as a broader discipline around the world\u201d.\u00a0The Volvo Environment Prize<\/b> was founded in 1988 and is awarded annually to people who have made outstanding scientific discoveries within the area of the environment and sustainable development. The prize consists of a diploma, a glass sculpture and a cash sum of SEK 1.5 million.<\/p>\n","protected":false},"excerpt":{"rendered":"
Xuemei Bai, a leading expert and thought leader on urbanization and sustainability, receives the Volvo Environment Prize 2018. More than half of the world\u2019s population lives in cities, and the trend keeps growing at an unprecedented rate.
