Over the past three decades, China’s unprecedented pace of urbanization has allowed more than 260 million migrants to move from agriculture to more productive activities. This has helped 500 million people escape poverty and for China to grow at an average 10 percent a year for three consecutive decades. At the same time, between 2000 and 2014, weather-related disasters caused more than RMB 4.645 trillion ($749 billion) in damages.
There is strong evidence that climate change is altering the profile of hazards. The observed frequency and severity of extremely heavy rain storms since the 1950s in China have significantly increased and future climate scenarios suggest that interannual variability in rainfall may increase further, aggravating the risk of flooding and as well as severe lack of water.
Over the past two decades, the city of Lishui in Zhejiang Province of China suffered from devastating floods, landslides, as well as heat waves. Today, the over 2 million people of Lishui have a lot to be proud of. Their city is recognized as China’s “top ecological, picturesque paradise for healthy life and home of longevity”. This is the result of close attention from city and provincial officials in understanding the root causes of the problems caused by the changing climate. This has been followed by inclusive planning, design and implementation of technically sound projects that are in harmony with the rivers flowing through the city in concert with the surrounding hilly terrain’s natural and city-wide storm water drainage systems.
