Here is a link to an article that mentions a technology that we may use in urban areas.
Those benefits, including reduced energy costs and better storm-water control, have been shown to march in lockstep with the size of trees.
“We tell municipalities that trees are as much a part of their infrastructure as the gas line, the sidewalk and the light pole,” says Mr. James, who is based in Vancouver. “And as such they belong not just to the arborist, but to the roads engineer, the streets engineer and the storm-water engineer.”
DeepRoot was founded in the United States in the 1970s with one product, a root barrier system that forces roots to grow down, not out, lessening the possibility of tree roots buckling pavement and sidewalks.
Over time, working with American landscape architect James Urban, the company developed the Silva Cell, a system designed to help nurture big trees in urban environments based on research that shows larger trees provide exponentially greater benefits than smaller ones. A 2010 report for the City of Toronto, for example, found a tree that’s 75 centimetres in diameter intercepts 10 times more air pollution, stores up to 90 times more carbon and contributes up to 100 times more leaf area to the city’s canopy than a 15-centimetre tree.
