New Study Suggests Disturbances Limit High-Resolution Predictions of Vegetation Dynamics and Carbon Flux
On April 19, 2016, Dr. George Hurtt, along with co-authors Quinn Thomas (Virginia Tech), Justin Fisk (Applied Geosolutions), Ralph Dubayah and Sage Sheldon, published a new paper entitled, "The Impact of Fine-Scale Disturbances on the Predictability of Vegetation Dynamics and Carbon Flux," in the international journal PLOS-ONE.
On May 4, 2016, Drs. Matt Hansen and George Hurtt - along with Nancy Harris from World Resources Institute and Dr. David Skole from Michigan State University – will be panelists for a session (Carbon Monitoring and Modeling in the Land Use Sector) at the University of Maryland Climate Action 2016 Forum. The Forum, which will run from 9:00 am - 4:30 pm in the Stamp Student Union, is open to the public and offers an opportunity for discussion among academia and stakeholders with an interest in advancing the climate implementation agenda.
On March 8, 2016, Scientific American published an article entitled, "Satellite Laser Will Map Forests in 3-D." The article discusses lidar technology and the goal of GEDI (Global Ecosystem Dynamics Investigation), which is to map Earth's forest from canopy to trunk in 3-D. The mechanism will be mounted on the international space station and report the data collected for at least two years, beginning in 2018. In this article, GEDI team members, GEOG Professor Matt Hansen and NASA Postdoc Fellow Laura Duncanson, were interviewed.
The first G-20 GEOGLAM Early Warning Crop Monitor (EWCM) bulletin was released on Friday, highlighting the severe drought conditions in southern Africa. The EWCM brings together the international, regional and national organizations monitoring crop conditions within countries at risk of food insecurity. The initiative is coordinated by Dr. Inbal Becker-Reshef and the focus is on developing timely consensus assessments of crop conditions, recognizing that reaching a consensus will help to strengthen confidence in decision making.
Drs. Krishna Vadrevu and Chris Justice organized a regional meeting on Land Use in Yangon, Myanmar (January 12-18, 2016) with support from the NASA Land Cover Land Use Change (LCLUC) Program, the global change SysTem for Analysis, Research and Training (START), the international Global Observation for Forest and Land Cover Dynamics (GOFC-GOLD) Program. 150 participants from 12 different countries attended the meeting including Department members, Matt Hansen, Tatiana Loboda, Chengquan Huang, Evan Ellicott, Demian Rybock and Sumalika Biswas to strengthen their research collaborations within the region.
In Light of Paris COP21 Conference This Week, 'Carbon All Around Us' Video Receives in Excess of 150,000 Views
The UN Climate Change Conference, COP21 (Conference of Parties-21), will take place over the next two weeks in Paris, France, despite the recent attacks. As a prelude, NASA's Goddard Space Flight Center released a Youtube video on November 19th entitled, "Carbon All Around Us." In the video, Dr.
The College of Behavioral and Social Sciences (BSOS) and the Department of Geographical Sciences (GEOG) join the University of Maryland (UMD) community in honoring the life of Brian Ross Melchior, who passed away on Saturday, October 24, 2015, after a yearlong battle with gastric cancer. Brian received both his B.S. in Environmental Science and Policy (2002) and his M.A. in Geography (2004) from UMD College Park. His Masters research, which was advised by Dr. Scott Goetz, focused on using land use and land cover metrics to predict stream and watershed health.
PhD candidate, Pui-Yu Ling, along with Drs. Giovanni Baiocchi and Chengquan Huang, developed a model framework that combines remote sensing data on forest disturbance, and forest inventory data on timber production, to produce improved estimates of carbon stored in forests and to broaden the reach of carbon accounting to include carbon stored in timber products.
On October 5, 2015, Dr. Joseph Sexton - along with co-authors Praveen Noojipady, Xiao-Peng Song, Min Feng, Dan-Xia Song, Do-Hyung Kim, Anupam Anand, Chengquan Huang, Saurabh Channan, Stuart Pimm and John Townshend - was published in the journal Nature. The paper, entitled, "Conservation policy and the measurement of forests," compared eight global, satellite-based maps to determine the planet's total forest area, and the information gaps this team uncovered were surprising!
