Phosphorous runoff in certain riparian areas of Canada, North Dakota and northern Minnesota can be mitigated by greater focus on management of runoff than on soil erosion, reports David Lobb, a University of Manitoba professor in the department of soil science. This will entail engaging in better land management to keep the water where it lands.
Pond expansion in the Mississippi Delta is a major contributor to land loss in the region, per a study by scientists from Indiana University and North Carolina State University. The culprits are waves that erode pond edges.
The stretch of Michigan's Kalamazoo River from M-89 to the Otsego Township Dam will stay closed to the public this summer due to dredging work now beginning on four more "Bank Removal and Stabilization Areas" of the river restoration project. Last year, more than 100 tons of sediment containing toxic polychlorinated biphenyls released from paper mills that once lined the river were removed.
After a winter shutdown, dredging work has resumed on two parts of Illinois' Lake Decatur. The goal of the $91 million project, which is now more than half complete, is to raise the capacity of the lake to provide 52 days' worth of more water by moving tons of sediment to a 523-acre storage site.
Texas' Harris County is studying whether it can mitigate flooding with high-powered pumps to flush water into aquifers or old oil wells and away from Houston. The hope is that this solution will also provide a source of water when drought hits the city.
Several Vermont cities and other organizations are looking to showcase for the public the value of reining in and controlling stormwater runoff. Their website, Rethinkrunoff.org, educates visitors with data, educational resources and engagement opportunities for residents to take steps to help keep Lake Champlain clean.
The National Flood Insurance Program will be up for renewal this year, and professional land surveyor Wendy Lathrop argues that it should be preserved. "I see it as improving the lives of many as it adapts to changing conditions imposed by land development, sea level rise, erosion and precipitation pattern changes," she writes.
Local authorities in India will have the tools to get a better handle on their water situations and address flood and drought conditions under a $175 million loan agreement between the Indian government and the World Bank. "The project is expected to help forge an integrated approach to developing, managing and regulating both surface and groundwater resources jointly at the basin and aquifer scale," said Raj Kumar, joint secretary in India's department of economic affairs.
A treehouse that's not only in a tree but practically becomes a part of it offers a greener solution to keeping its occupants comfortable. The concept by Anthony Leung, a civil engineering lecturer at the UK's University of Dundee, uses the tree's trunk as a support column and transpiration -- how a tree regulates its metabolism -- to moderate temperatures inside using a circulation system that takes advantage of the house's green roof and climbing plants on exterior walls.
Researchers at Children's Hospital of Philadelphia have developed a device to improve the chances of extremely premature babies. The key is a focus on more fully developing the newborn's organs with a fluid-filled environment that mimics the womb.
