How preprocessing methods affect the conversion efficiency of biomass energy production
URBANA, Ill. – Research on energy production from biomass usually focuses on the amount of energy generated. But it is also important to consider how much energy goes into the process, a component that is often neglected, says Tony Grift, professor of Agricultural and Biological Engineering in the College of Agricultural, Consumer and Environmental Sciences and the Grainger College of Engineering at the University of Illinois.
Land management practices to reduce nitrogen load may be affected by future climate changes
URBANA, Ill. – Nitrogen from agricultural production is a major cause of pollution in the Mississippi River Basin and contributes to large dead zones in the Gulf of Mexico.
Illinois and other Midwestern states have set goals to reduce nitrogen load through strategies that include different land management practices. A new study from University of Illinois researchers, published in Journal of Environmental Management, uses computer modeling to estimate how those practices may be affected by potential changes in the climate, such as increased rainfall.
Chicago water pollution may be keeping invasive silver carp out of Great Lakes, study says
URBANA, Ill. – Invasive silver carp have been moving north toward the Great Lakes since their accidental release in the 1970s. The large filter-feeding fish, which are known to jump from the water and wallop anglers, threaten aquatic food webs as well as the $7 billion Great Lakes fishery. But, for the past decade, the invading front hasn’t moved past Kankakee. A new study, led by scientists at the University of Illinois, suggests that Chicago’s water pollution may be a contributing to this lack of upstream movement.
Illinois scientists receive USDA NIFA grant to develop soil erosion evaluation tool
URBANA, Ill. – Two University of Illinois scientists received a $500,000 grant from the USDA National Institute of Food and Agriculture (NIFA) to develop a computational tool that stakeholders can use for estimating and predicting soil erosion.
“Quantifying soil erosion is a very complex problem because of the variability in time and space,” says Maria Chu, assistant professor of Agricultural and Biological Engineering (ABE) in the College of Agricultural, Consumer and Environmental Sciences. Chu is principal investigator on the grant.
ACES graduate receives Fulbright grant to study bioenergy systems in Finland
URBANA, Ill. – Jordan Blake Banks recently arrived in Finland, where she’ll begin a two-year Master’s program in bioenergy systems at the Lappeenranta-Lahti University of Technology (LUT). She is one of two 2019 graduates from the College of Agricultural, Consumer and Environmental Sciences to receive a Fulbright scholarship for continued studies.
Banks spent her first weeks abroad participating in a Finnish language and culture course. Now she’s ready to start at LUT, which offers an international Master’s program with classes taught in English.
Wind turbine design and placement can mitigate negative effect on birds
URBANA, Ill. – Wind energy is increasingly seen as a sustainable alternative to fossil fuels, as it contributes to a reduction in greenhouse gas emissions. It is estimated that by 2050, wind turbines will contribute more than 20% of the global electricity supply. However, the rapid expansion of wind farms has raised concerns about the impact of wind turbines on wildlife.
Research in that area has been limited and has yielded conflicting results. A new study, published in Energy Science, provides comprehensive data on how turbines affect bird populations.
Tornadoes, windstorms pave way for lasting plant invasions
URBANA, Ill. – When tornadoes touch down, we brace for news of property damage, injuries, and loss of life, but the high-speed wind storms wreak environmental havoc, too. They can cut through massive swaths of forest, destroying trees and wildlife habitat, and opening up opportunities for invasive species to gain ground.
Human waste an asset to economy, environment, study finds
CHAMPAIGN, Ill. — Human waste might be an unpleasant public health burden, but scientists at the University of Illinois see sanitation as a valuable facet of global ecosystems and an overlooked source of nutrients, organic material and water. Their research is reported in the journal Nature Sustainability.
Rethink environmental regulations in Africa, study urges
URBANA, Ill. – Conflict over resource extraction is rampant in sub-Saharan Africa, with small-scale miners violently pitted against multinational mining corporations – and the state security forces that protect them – for access. Attempts to solve the problem by imposing Western environmental systems and regulations aren’t working. But it’s not for the reasons most experts might suspect, according to a new Illinois study.
A warming Midwest increases likelihood that farmers will need to irrigate
CHAMPAIGN, Ill. — If current climate and crop-improvement trends continue into the future, Midwestern corn growers who today rely on rainfall to water their crops will need to irrigate their fields, a new study finds. This could draw down aquifers, disrupt streams and rivers, and set up conflicts between agricultural and other human and ecological needs for water, scientists say.
