Advanced tools are needed which provide critical timelag and feedback information for making environmental policy decisions, as Minnesota prepares to launch the Groundwater Protection Rule and nutrient reduction strategies.
Pesticides, pharmaceuticals, and agricultural nutrients serve important functions in crop production and the treatment of disease. However, these chemicals become pollutants when discharged into surface waters through wastewater, storm water, and agricultural runoff. There are natural processes, though, that help break down and remove these pollutants from water. One such process is the role that sunlight interacting with dissolved organic matter naturally present in surface water from decaying plant materials and algae has in transforming these contaminants.
Sustainable energy production is a major challenge facing our society. Solar energy is renewable and is a viable and attractive option. However, there are obstacles to widespread use. Current technology is expensive, making it difficult for businesses and homeowners to implement, and solar cells are commonly made using toxic and rare elements or using processes that require large amounts of energy. To become commonplace, solar cells must be inexpensive and robust, and they must be made of abundant, cheap, nontoxic materials.
Native trout require clean, cold water that usually originates from springs, but the springs feeding the 173 designated trout streams in southeastern Minnesota are under increasing pressure from current and expected changes in land use. This joint effort by the University of Minnesota and the Minnesota Department of Natural Resources is working to identify and map the springs and the areas that feed water to these springs and to learn how these waters might be affected by development and water use.
Our primary objective is to understand how to harvest timber in the boreal forest in a way that enables species with limited movements to thrive in a changing landscape.
Producing new materials from regional plant byproducts for renewable solar energy. This project engages many students in environmental research; this homegrown technology will ultimately provide affordable energy to Minnesota families.
We will develop technologies that utilize indigenous microbes to convert waste plastics into useful chemical compounds and fuels, lowering the likelihood that these materials end up in our environment.
Production agriculture’s dependence on fossil fuel energy carries significant economic and ecological risks. The energy consumed within livestock facilities alone is the equivalent consumption of several large cities, and agriculture currently contributes approximately 14% of the total greenhouse gas emissions in the state. As consumers increasingly demand low carbon footprint products, adoption of clean energy systems in crop and livestock production would position Minnesota’s agricultural sector with a competitive advantage.
A class of insecticides known as systemic neonicotinyl insecticides has been identified as a potential factor in recently observed declines in pollinators, including the phenomenon amongst honeybees known as Colony Collapse Disorder. Previous research examining the effects of neonicotinyl insecticides on lab colonies of bumblebees found that exposure to these insecticides at various levels increased queen bee mortality and detrimentally altered bee behavior and production.
A 2017 workshop determined we don’t know enough about brainworm transmission to moose and what mitigation strategies are optimal. We’ve assembled a multidisciplinary team to tackle the highest research priorities.
Pharmaceuticals, hormones, and other contaminants of emerging concern (CECs) are found in surface waters in Minnesota and nationally. CECs can cause adverse ecological and human health impacts, and occur as complex mixtures in the environment. One of the greatest barriers to addressing the problem of CECs is a lack of understanding of where these compounds come from and which sources dominate in different locations and at different times.
Land and water conservation efforts require accurate information about land cover and land use. Minnesota’s land cover and land use data has not been updated since 2000 and so does not reflect changes since that time resulting from growth and development, agricultural production, or landscape cover. Researchers at the University of Minnesota are using this appropriation to conduct a statewide update and enhancement of land cover and land use data and make it freely available online for use by government and non-government organizations involved in land and water conservation.
Provide industrial, source reduction technical assistance to reduce nutrient discharge to wastewater treatment facilities through industrial process optimization. Document impact of nutrient reduction on wastewater operations and discharge quality.
