Among the predictions about climate change increasing warming and increasing temperature in the Midwest, a new study led by researchers at the University of Maryland found that growing a single perennial grass can cut the Midwest temperature by 1 degree Celsius.
Miscanthus x giganteus, also known as giant miscanthus, grows up to 10 feet tall with shrubs such as broad reeds and green leaves, creating a canopy that lowers the earth’s temperature. summer with increasing humidity, rainfall and overall productivity, according to published research. inside GCB Bioenergy.
The study was led by scientists Xin-Zhong Liang and Yufeng He. It provides new insights into environmental mitigation initiatives for global warming, environmental conservation, food and bioenergy production, and sustainable agriculture.
“Growing perennial grasses in marginal lands cannot reduce soil compaction, restore carbon deposits, and provide nutrients for biofuels and bioproducts,” Liang said. , “but it could be an effective mitigation strategy to achieve climate change, protecting U.S. agricultural land.. from the kind of warmth and drought currently expected.”
Miscanthus x giganteus is water-good, noninvasive and requires little to no plants. It can grow on small land, or land that has no agricultural or industrial resources due to poor soil or other conditions. The heartland of America, with marginal land that is not used or eaten in large quantities, provides ideal conditions for miscanthus.
The researchers combined a growth model with a landscaping model to show that miscanthus worked before resting on the ground – significantly increasing summer rainfall. In Midwest comparisons, summer rainfall increases between 14% and 15%; in the south, it increased by between 14% and 16%.
Unlike temperature changes, which are more common in areas with large amounts of miscanthus, rainfall can change hundreds of miles before the air flows.
“Global warming will continue to rise as a result of climate change, even if we can prevent global warming and develop new technologies to remove greenhouse gases. carbon, ”said Laura Lautz, project manager in NSF’s Division of Earth Science. “This research joins our workforce of initiatives to reduce the effects of future warming, improve food security, and improve the sustainability of agricultural systems.”
The company is conducting research behind bioenergy plants in the marginal US. Scientists have found that reed, a genetically modified form of sugarcane, is better in the Southern states than miscanthus in the North.
