Study reveals human destruction of global floodplains

has had on floodplains," Rajib said."In 27 years, between 1992 and 2019, the world has lost a dramatic 600,000 square kilometers of floodplains due to human disturbances, which include infrastructure development, industry and business construction and expansion of agriculture."

"Mapping the world's floodplains is relatively new. While there is increasing awareness to map floodplains accurately and understand flood risks, an attempt to map human disturbances in those floodplains at a global scale never existed," said Rajib, who also is the director of the UT Arlington Hydrology and Hydroinformatics Innovation Lab.

"We wanted to look at floodplains at the neighborhood level," Zheng said."We wanted to see the impact of development on someone who lives adjacent to or near a floodplain. Some of the changes in these pictures are good, like when trees are planted or parks are built. But many of the pictures reveal disturbing outcomes. For instance, we saw a dramatic increase in the development of parking lots or the construction of buildings without adequate stormwater runoff allowances.

Why bats carry viruses that have higher fatality rates in humans than those from other mammalsA small team of biologists and evolutionists from the University of Chicago, York University, the University of California, Berkeley, and the University of Exeter reports why bats carry viruses that cause higher fatality rates when jumping to humans than those that come from any other mammal. In their study, reported on the open-access site PLOS Biology, the group used data from past research efforts to model the growth of viruses within bat populations as well as their spread to other animals.
