Cities can be carbon sinks too: study › News in Science ABC Science   Leave a comment

The concept that greenspace and urban_forests can act as a carbon sink in cities is helpful to consider . Any promotion of greenspace and additional tree plantings in cities should be encouraged.

“Urban sinks are not by themselves a solution to the billions of tonnes of carbon emitted globally, but can help mitigate their impact, especially if gardeners grow trees, which absorb far more CO2 than grass and shrubs, she says.In the case of Leicester, most of the publicly-owned or -managed land in the city comprises lawns. But if just 10 per cent of this land were planted with trees, the citys carbon storage would leap by 12 per cent.”If more trees are planted in urban areas for their carbon storage value, they must be the right kind of tree planted in the right place so that they have a long, productive lifespan, and when trees die they should be replaced,” says Davies.”

Green Space in Cities: What’s a Tree Really Worth? | This Big City   Leave a comment

Trees can provide aesthetic value but what other tangible value ? Cabon sequestation, energy savings through shade cooling, pollution reduction and more. The values add up significantly. Read in full…

 

“Beyond their aesthetic value, trees provide vital ecosystem services: cleaning the air, managing rainfall, storing carbon, reducing noise pollution and stabilising temperatures. Take out a tree, and you lose a free service. But until now, little assessment of the financial burden caused by the damage or destruction of local trees has been undertaken in the UK.

Torbay Council’s Arboricultural Services team is using i-Tree Eco software to measure the environmental services and corresponding financial values of local trees. The project, a collaboration involving Forest Research and Natural England, collects data on the way trees:

• save energy: their shade cools buildings in summer, and offers some shelter from winter winds

• store and sequester carbon (and at what rate)

• reduce pollution through filtration.

It will also assess the ‘structural value’ of the trees, including the cost of replacement. The findings will be used to establish a UK-wide benchmark for valuing trees.”
