Deadly floods sever Nepal-China trade, exposing the cost of climate-vulnerable infrastructure

Floods that damaged hydropower dams in Nepal and destroyed the main bridge connecting the country to China show the vulnerability of infrastructure and the need for smart rebuilding in a region bearing the brunt of a warming planet, experts say. The flooding of the Bhotekoshi River on July 8 also killed nine people and damaged an inland container depot that was being built to support increasing trade between the two countries. The 10 damaged hydropower facilities, including three under construction, have a combined capacity that could power 600,000 South Asian homes. Another smaller flood in the area on July 30 damaged roads and structures, but caused less overall destruction. Nepal's location in the Himalayan mountains makes it especially vulnerable to heavy rains, floods and landslides because the area is warming up faster than the rest of the world due to human-caused climate change. Climate experts say the increasing frequency of extreme weather has changed the playbook for assessing infrastructure risks while also increasing the need for smart rebuilding plans. 'The statistics of the past no longer apply for the future,' said John Pomeroy, a hydrologist at the University of Saskatchewan in Canada. 'The risk that goes into building a bridge or other infrastructure is generally based on historical observations of past risk, but this is no longer useful because future risk is different and often much higher.' While damage estimates from the July floods in the Rasuwa region are still being calculated, past construction costs give a sense of the financial toll. The Sino-Nepal Friendship Bridge alone, for example, took US$68 million to rebuild after it was destroyed by a 2015 earthquake that ravaged Nepal.

American Mathematical Society fellow Li Hanfeng joins China's Chongqing University

There are four top-tier journals in mathematics academia: Annals of Mathematics, Inventiones Mathematicae, Journal of the American Mathematical Society and Acta Mathematica. These journals put out only about 100 articles each year, and publishing even one is a mark of a leading mathematician. It is very rare to publish in all four. Li Hanfeng published 10 in total across all four between 2005 and 2019. The leading China-born mathematician has now returned from the United States. Chongqing University announced his appointment as a professor last month, and his name is listed on the university's website. Li earned his bachelor's degree in mathematics from Peking University in 1997 and his PhD from the University of California, Berkeley in 2002.
