Drone Flights Give Scientists Better Data on Vegetation in the Arctic Tundra
Scientists use various satellite and airborne systems to study how vegetation changes in response to climate change. However, these systems have low resolution that makes it hard to identify detailed patterns. This is especially true in the Arctic due to the region’s highly mixed vegetation. Now, scientists have adopted unoccupied aerial systems—also known as drones—for high-resolution vegetation monitoring.

Study led by NUS researchers reveals climate change increases fluvial sediment in the high mountains of Asia
To examine the impact of a warmer and wetter climate in High Mountain Asia, Professor Lu Xixi and Dr Dongfeng Li from the Department of Geography at the National University of Singapore (NUS) Faculty of Arts and Social Sciences led an international team of researchers to conduct a new analysis of observations of headwater rivers in the area. The study revealed that fluvial sediment loads have been increasing substantially, even much faster than river water discharge. This has important implications for water quality, hydropower development and maintenance, and for the riverine carbon cycle.
