Colloquium: Water Crisis: Need "Imagineering" Not Just Engineering to Solve Water Security Challenges
Dr. Murugesu Sivapalan  
Geography & GIS, Civil & Environmental Engineering

Many parts of the world, including parts of the United States and even suburbs of Chicago, are facing severe water crises. Historically engineers and domain experts are tasked with the design and implementation of technological solutions to water problems, such as the building of dams, pipelines and desalination plants. These work well in the short term, but the non-involvement of the beneficiaries of the water works, the people themselves, in the conceptualization and execution of otherwise well-intentioned and well-designed solutions often leads to unintended, often adverse, consequences due to issues not considered in the design of the solutions and due to their non-acceptance by society.

Seminar Series: Time Series Remote Sensing in Monitoring the Riparian Vegetation Dynamics
Dr. Chunyuan Diao   Department of Geography and GIS

Invasive species threaten the functioning of natural ecosystems and cause substantial economic losses at the global scale. Over the past century, non-native saltcedar (Tamarix spp.) has expanded into most of riparian zones in the southwestern United States and posed significant threats to the native biotic communities. In today’s big data era, large volumes of remotely sensed information (e.g., time series of satellite imagery) open up new paradigms for evaluating the ecological disturbance of the riparian ecosystems. In this seminar, I will first present an overview of the integrated time series remote sensing framework I have developed to monitor the spatio-temporal dynamics of riparian vegetation species. I will then discuss how time series remote sensing can be leveraged to investigate the influence of environmental gradients on riparian vegetation distributions. My goal is to improve our understanding of earth system dynamics with the time series remote sensing in this big data era.

Prof. Shaowen Wang gave a keynote speech at the inaugural United Nations World Geospatial Information Congress (UNWGIC) held in Deqing, Zhejiang Province, China from 19 - 21 November 2018. He also promoted GGIS academic and research programs at the booth of Zhejiang University that is the partner of our 3+2 program.

Prof. Mei-Po Kwan delivered an NCGIA Distinguished Lecture at the University of Buffalo (SUNY) on November 9. In addition, she delivered a keynote address as the central event of the Vanderbilt GIS Days at Vanderbilt University on November 16.
