Relationship between boreal forest fires and drought conditions

A study on relationship between boreal forest fires and drought conditions in the last half century has been just published online in Environmental Research Letters ( Published 27 November 2007 Online at

Our lab was just awarded by DOE with a project, entitled Analysis Of Global Economic And Environmental Impacts of A Substantial Increase In Bio-energy Production?


The goal of this research is to develop realistic assessments of the economic and environmental impacts of regional and global policies designed to stimulate bioenergy production and use. We will build on the unique strengths of GTAP to analyze economic impacts of alternative bioenergy policies at regional and global levels. We will use the TEM model to help develop the land supply curves and to validate environmental consequences of these policies and check their feasibility from the environmental and land use perspectives.

The EBDL is funded by the NSF Carbon and Water in the Earth System Program for the project, entitled "Collaborative Research: Impact of Permafrost Degradation on Carbon and Water in Boreal Ecosystems".

Purdue University is the lead institution in this collaborative project; three other institutions are the United States Geological Surveys, University of Alaska Fairbanks, and Alaska Ecological Surveys. During five-year project period, this project will generate a new approach to modeling boreal forest systems by using research tasks designed to

  1. assess interactive effects of climate change and fire on permafrost stability;
  2. quantify how the varying modes of permafrost degradation initiate various thaw regimes on the landscape by affecting the microtopography, drainage, and soil thermal regimes of boreal systems;
  3. determine how various thaw regimes such as drained or ponded systems affect carbon loss or accumulation in biomass and soils, and
  4. characterize the export of dissolved organic carbon from watersheds in an effort to fingerprint the various thaw regimes induced by permafrost degradation.

The Energy Center, Discovery Park, Purdue University selected the EBDL to study the global biomass and bio-energy supply and its environmental and socioeconomic consequences.


The funded project of "Global Biomass and Bioenergy Supply in a Coupled Natural and Human System" is a part of a new bioenergy initiative at Purdue. Our lab is collaborating with the researchers at the Department of Agricultural Economics in executing the project. Our first objective for the project is to develop an integrated framework of ecosystem and energy and economic models. The existing terrestrial ecosystem models and the models of Global Trading Analysis Project (GTAP) will be the basis for the framework, which will be used to comprehensively assess the prospects for future sustainable global biomass and bioenergy.
