Landscapes for People, Food and Nature: a new Blog from Bioversity, FAO, UNEP et al

Landscapes for People, Food and Nature: a new Blog from Bioversity, FAO, UNEP et al | forest gardening | Scoop.it

A new blog on Landscapes for People, Food and Nature is launched today. Fortunately, its just in time for a new University of Leicester undergraduate module Biodiversity and Sustainability. The blog is asking "How can we manage our farms and farming landscapes not just to supply food for 9 billion people over the next few decades, but do so in ways that also secure our water needs, conserve biodiversity, manage climate change, and sustain rural livelihoods?"

The blog goes on to say "many of the most important habitats for wild biodiversity, watersheds, forest products, bio-energy, and stores of carbon were located in agricultural lands—not just those “marginal lands” but in the world’s main breadbaskets and rice bowls." which happens to be one of the points I was preparing to include in my first lecture, although one before this that I would have found hard to reference.

The High Cost of Losing Urban Trees

The High Cost of Losing Urban Trees | forest gardening | Scoop.it
Tennessee reaps a $638 million yearly benefit from its urban trees – and an $80 billion loss if they disappeared.

Through energy savings, air and water filtering and carbon storage, the urban trees of Tennessee account for more than $638 million in benefits, according to a report [PDF] conducted by the Forest Service of the U.S. Department of Agriculture and released earlier this year.

The biggest savings are attributed to carbon storage, which the authors of the report value at an estimated $350 million. Collectively, the state's urban trees store about 16.9 million tons, with each ton stored worth about $20.70 to the state every year. Air and water filtration is also one of the functional benefits of urban trees, and the report estimates the value of this work at $204 million per year. The trees are credited with removing 27,100 tons of pollutants each year, including ozone, particulate matter, and sulfur dioxide. And because of the shading they provide, these urban trees are credited with saving about $66 million in energy costs annually.
