At the invitation of Researcher Ma Xuanlong from the School of Resources and Environment, Lanzhou University, Professor Alfredo Huete from the University of Technology Sydney, Australia, gave an online academic report to our school on July 5, 2023.

Title:Ecological resilience of dryland ecosystems from space: progress & issues

Reporter:DistinguishedProfessor Alfredo Huete(University of Technology Sydney, Australia,)

Moderator：Researcher Ma Xuanlong

Time:July 5th, 2023(Wednesday), 14:30-16:00

Tencent Meeting ID: 487-397-337

Report summary:

Ecological resilience, also known as ecosystem resilience, refers to the ability of an ecosystem to recover its normal state and function after being disturbed by environmental events such as extreme weather. In the context of increasing frequency and intensity of extreme weather events such as drought and high temperatures caused by climate change and human activities, research on ecosystem resilience based on satellite remote sensing can provide scientific basis for defining the scope of vulnerable ecosystems at the macro scale and formulating corresponding protection policies. This report focuses on the application of satellite remote sensing in ecosystem resilience, and based on the work of the research group of the reporter in recent years, sorts out the latest progress and existing opportunities and challenges in this field.

Reporter profile:

Dr. Alfredo Huete, Distinguished Professor at the University of Technology Sydney, Australia, former professor at the University of Arizona, internationally renowned environmental remote sensing expert, member of the satellite expert group of NASA’s EOS/MODIS, EO-1/Hyperion, etc., senior consultant of ESA’s Sentinel program for near-Earth satellite systems, Japan’s GCOM-SGLI and Himawari satellite program, developer of vegetation indices such as SAVI/EVI, editorial board member of top international remote sensing journal Remote Sensing of Environment, associate editor of well-known remote sensing journals such as Journal of Remote Sensing and Remote Sensing. Professor Huete has long been committed to research in the fields of vegetation-climate interaction and development of scientific products for Earth observation satellites. He has published more than 300 academic papers in the fields of vegetation remote sensing and global ecology, with a total citation of more than 60,000 times and an H-index of 92. His two most classic first-author papers on satellite remote sensing vegetation indices have been cited more than 8,000 times each, establishing his academic position in the field of vegetation remote sensing. The MODIS vegetation index product developed under the leadership of Dr. Huete is one of the most widely used global-scale satellite remote sensing products in the world to date.
