Princeton study: Amazon deforestation could mean droughts for western US

Understanding our interconnected and interdependent world: In research meant to highlight how the destruction of the Amazon rainforest could affect climate elsewhere, Princeton University-led researchers report the total deforestation of the Amazon may significantly reduce rain and snowfall in the western United States, resulting in water and food shortages, and a greater risk of forest fires. The researchers report in the Journal of Climate that an Amazon stripped bare could mean 20 percent less rain for the coastal Northwest and…

Carbon storage recovers faster than plant biodiversity in re-growing tropical forests

A new study of re-growing tropical forests has concluded that plant biodiversity takes longer to recover than carbon storage following major disturbances such as clearance for farming. The findings, published in the scientific journal Proceedings of the Royal Society B, have important implications for conservation since there are now many re-growing forests in South and Central America. The new study is the first large-scale analysis of the recovery of both plant biodiversity and carbon pools in re-growing forests. Over half…

Turfgrass tested in shallow green roof substrates

Many of us get absolutely excited about the idea of a green roof. It’s not so easy as our vision might like it to be, however. First of all, there are structural issues that have to be considered in order to support the added weight of so much dirt. Second, there is the issue of water — whatever is planted up high will require some form of irrigation. Third, there is the daunting challenge of planting something that will survive,…

What are Building-Integrated Photovoltaics (BIPV)?

Our thanks to Mathias Maehlum from Energy Informative for providing GBE readers with a series of informative articles on solar energy technologies like BIPV. His next two articles, “Zero-Down Solar Leasing for New Homes,” and “NREL Sets New World Record with Two-Junction Solar Cell,” will be published this week. Some homeowners are turned off by how solar panels affect the appearances of their homes. Building-integrated photovoltaics – basically solar panels incorporated into the construction of new buildings – can eliminate the negative visual impact…

Case Study: Eagleyew – A High Efficiency Natural Building on Vancouver Island, B.C., Canada

The Story of Eagleyew: A High Efficiency Natural Building on Vancouver Island, B.C., Canada I’m pleased to say that I have been building Natural Buildings for a number of years now. My work has taken me up and down the West coast of North America, with a focus in the Pacific Northwest. I’ve been calling Vancouver Island home for the last three years, and have had the pleasure of working on some amazing Natural Homes in the area. From cob…
