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.

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.

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.
