Yale’s Chad Oliver Honored For Contributions to Forest Science (By Kevin Dennehy)

Yale Professor Chadwick Dearing “Chad” Oliver will be awarded the prestigious Host Country Scientific Achievement Award from the International Union of Forest Research Organization (IUFRO), the largest global network of forest researchers, during its World Congress in Salt Lake City in October.

He is one of three recipients of the award, which recognizes outstanding career achievements by scientists from the nation hosting the event. The last World Congress hosted by the U.S. was held in 1971.

Oliver, the Pinchot Professor of Forestry and Environmental Studies and Director of the Global Institute of Sustainable Forestry at the Yale School of Forestry & Environmental Studies (F&ES), is being honored for contributions to silviculture, forest ecology, and sustainable resource management.

According to U.S. Forest Service, which is hosting the World Congress, Oliver’s work has deepened the scientific understanding of basic biophysical processes of forest dynamics and the interactions of human societies and forests at multiple scales.

“There are so many excellent forest scientists that I am extremely honored to have been chosen for this award,” said Oliver. “I thank the people who nominated me and my family, friends, and teachers — from the Camden [South Carolina] public schools, The University of the South, Yale University, and The Harvard Forest.

“I have also been fortunate to work with a lot of stimulating forestry professionals, scientists, and students. We would identify a practical problem and set about solving it — changing scientific theory and/or forestry practices as necessary. We would ignore physical hardships, political boundaries, and scientific fads and simply focus on the problem and its solution.”

Oliver, whose early work focused on the basic understanding of how forest stands develop and can be managed silviculturally, has expanded his research to explore how this understanding can help resolve scientific, technical, environmental, and management issues at the landscape and global levels.

His Landscape Management System — a downloadable, computer-based tool for managing timber resources, wildlife habitat, carbon sequestration, and fire protection — has been used widely to analyze and visualize the effects of disturbances and management on landscapes.

“This richly deserved honor recognizes Chad Oliver as one of the preeminent forestry scientists of his generation,” said Peter Crane, Dean of F&ES. “During his career, he has helped us better understand how forests develop, at multiple scales and in all parts of the world, and how they can be more sustainably managed.”

Other recipients of the Host Country Scientific Achievement Award this year are Harold Burkhart of Virginia Polytechnic Institute and Stephen Hubbell of the University of California at Los Angeles.

During the World Congress, Yale F&ES Professor Benjamin Cashore will receive IUFRO’s Scientific Achievement Award for his work related to the governance of forest resources worldwide.

The World Congress is held every four to five years in different countries worldwide. Forest scientists from throughout the world will present scientific and technical issues related to priority areas of forest research, policy, and management. This year’s event, which is being held from Oct. 5 to 11, is expected to draw 2,500 forest scientists from 100 nations.

IUFRO is a non-profit, non-governmental international network of 700 research organizations with over 15,000 forest scientists. Founded in 1892, it is the largest global network promoting global cooperation in forest-related research to deepen the understanding of the ecological, economic and social aspects of forests and trees and how they benefit societies.

Using more wood for construction can slash global reliance on fossil fuels

Using more wood for construction can slash global reliance on fossil fuels (Yale News by  Kevin Dennehy)

A Yale University-led study has found that using more wood and less steel and concrete in building and bridge construction would substantially reduce global carbon dioxide emissions and fossil fuel consumption.

Despite an established forest conservation theory holding that tree harvesting should be strictly minimized to prevent the loss of biodiversity and to maintain carbon storage capacity, the new study shows that sustainable management of wood resources can achieve both goals while also reducing fossil fuel burning. The results were published March 28 in the Journal of Sustainable Forestry.

In the comprehensive study, scientists from the Yale School of Forestry & Environmental Studies (F&ES) and the University of Washington’s College of the Environment evaluated a range of scenarios, including leaving forests untouched, burning wood for energy, and using various solid wood products for construction.

The researchers calculated that the amount of wood harvested globally each year (3.4 billion cubic meters) is equivalent to only about 20 percent of annual wood growth (17 billion cubic meters), and much of that harvest is burned inefficiently for cooking. They found that increasing the wood harvest to the equivalent of 34% or more of annual wood growth would have profound and positive effects:

•    Between 14% and 31%  of global CO2 emissions could be avoided by preventing emissions related to steel and concrete; by storing CO2 in the cellulose and lignin of wood products; and other factors.

•    About 12% to 19% of annual global fossil fuel consumption would be saved including savings achieved because scrap wood and unsellable materials could be burned for energy, replacing fossil fuel consumption.

Wood-based construction consumes much less energy than concrete or steel construction. Through efficient harvesting and product use, more CO2 is saved through the avoided emissions, materials, and wood energy than is lost from the harvested forest.

“This study shows still another reason to appreciate forests — and another reason to not let them be permanently cleared for agriculture,” said Chadwick Oliver, the Pinchot Professor of Forestry and Environmental Studies, director of the Global Institute of Sustainable Forestry at F&ES and lead author of the new study. “Forest harvest creates a temporary opening that is needed by forest species such as butterflies and some birds and deer before it regrows to large trees. But conversion to agriculture is a permanent loss of all forest biodiversity.”

The manufacture of steel, concrete, and brick accounts for about 16 percent of global fossil fuel consumption. When the transport and assembly of steel, concrete, and brick products is considered, its share of fossil fuel burning is closer to 20% to 30%, Oliver said.

Reductions in fossil fuel consumption and carbon emissions from construction will become increasingly critical as demand for new buildings, bridges and other infrastructure is expected to surge worldwide in the coming decades with economic development in Asia, Africa, and South America, according to a previous F&ES study. And innovative construction techniques are now making wood even more effective in bridges and mid-rise apartment buildings.

According to Oliver, carefully managed harvesting also reduces the likelihood of catastrophic wildfires. 

And maintaining a mix of forest habitats and densities in non-reserved forests — in addition to keeping some global forests in reserves — would help preserve biodiversity in ecosystems worldwide, Oliver said. About 12.5% of the world’s forests are currently located in reserves.

“Forests historically have had a diversity of habitats that different species need,” Oliver said. “This diversity can be maintained by harvesting some of the forest growth. And the harvested wood will save fossil fuel and CO2 and provide jobs — giving local people more reason to keep the forests.”

The article, “Carbon, Fossil Fuel, and Biodiversity Mitigation with Woods and Forests,” was co-authored by Nedal T. Nassar of the Yale School of Forestry & Environmental Studies and Bruce R. Lippke and James B. McCarter of the University of Washington.

Yale Researchers Receive Google Earth Engine Award for Land Studies

Yale Researchers Receive Google Earth Engine Award for Land Studies.

Using satellite imagery embedded with data on reflectance, the UHPSI team will work on developing statistical tools that rapidly scan a large area to locate plants or land-cover of particular interest. In northeastern Wyoming, the team will be using the tools to locate leafy spurge (Euphorbia esula; displayed within the inset image above), an invasive species that displaces native rangeland vegetation.

In support of their ongoing land stewardship studies in Wyoming, a team of Yale researchers has received a “Google Earth Engine Research Award.” The award will help the Ucross High Plains Stewardship Initiative make advanced methods for rapid land-cover detection and assessment available to the public through the use of freely available satellite data.

Specifically, they will work to integrate various statistical methods into Google’s new Earth Engine platform as preset tools that will allow users to evaluate vegetation or land-cover types of interest for any area of the globe.

These preset tools will be available to anyone in the world with an Internet connection and a Google account.

The Ucross High Plains Stewardship Initiative is a partnership between the Yale School of Forestry & Environmental Studies (F&ES) and the Ucross Foundation, and is directed by F&ES professor Chadwick Oliver.
Their research will incorporate contemporary methods for remote sensing, coding, and multivariate statistical analysis. The team expects to release its work at the end of 2014.
The Ucross Foundation is located on a 20,000-acre working cattle ranch in Clearmont, Wyoming.
