College Park, Md.—New research led by the University of Maryland (UMD) Department of Geographical Sciences employs satellite image time series to better understand the dynamics of forest cover loss in the Brazilian Amazon. While rates of deforestation in the country have slowed significantly over the last decade, Brazil remains the single largest contributor to natural forest loss among tropical countries.
Researchers Katharina Brinck, Rico Fischer, Jürgen Groeneveld, Sebastian Lehmann, Mateus Dantas De Paula, Sandro Pütz, Joseph O. Sexton, Danxia Song & Andreas Huth recently published their article titled "High resolution analysis of tropical forest fragmentation and its impact on the global carbon cycle" in the esteemed Nature Communications. This recent publication describes how deforestation in the tropics is not only responsible for direct carbon emissions but also extends the forest edge wherein trees suffer increased mortality.
The framing of a new research agenda initiated by Dept. Chair, Chris Justice has been published by the Pardee Center for the Study of the Longer-Range Future as part of their report series. According to the UN’s Food and Agricultural Organization (Statistics Division 2016), a relatively small area of the world, 23 percent of total cropland, accounts for a large proportion of total global cereal production, with most of the area devoted to three major cereal crops: maize (70.3 percent), wheat (69.3 percent), and rice (84.5 percent).
COLLEGE PARK, Md.—For more than a decade, scientists have debated what’s known as the “green up” phenomenon in the Amazon rainforest—when vegetation appears to thrive and grow fuller during the dry season with little or no rainfall. While some researchers have supported hypotheses that drought-induced growth does occur in the Amazon, others have argued it is more likely an optical illusion created by shadows cast from satellite positioning.
Geographers Hubacek and Feng contributed to a new position paper by an international team of distinguished scientists, including five members of the National Academies, which argues that there are critical two-way feedbacks missing from current climate models that are used to inform environmental, climate, and economic policies. The most important inadequately-modeled variables are inequality, consumption, and population.
UMD researchers measure global loss of intact forest landscapes COLLEGE PARK, Md.—Researchers from the University of Maryland utilize satellite imagery to demonstrate that forest wildlands—forests least affected by human activity—are steadily shrinking and pinpoint ways to help preserve these landscapes that are critically important to the health of the planet.
In August 2016, Dr.Tatiana Loboda and PhD student Dong Chen in collaboration with Liza Jenkins of the Michigan Technological Research Institute spent sixteen days in the remote wilderness of Alaskan tundra collecting field observations of wildfire impact on this sensitive ecosystem. The researchers navigated over 100 miles of the Noatak River and bushwhacked nearly 35 miles of wilderness to collect their data. This project is funded by NASA as part of the Arctic Boreal Vulnerability Experiment (ABoVE) field campaign that aims to link field, airborne, and satell
Drs. Loboda, Stewart, and Silva (Geographical Sciences) have been awarded a NASA Land Cover Land Use Change Grant for their project, Understanding the role of land cover / land use nexus in malaria transmission under changing socio-economic climate in Myanmar.
