Third IGBP Congress

Banff, Canada, 19-24 June 2003


The Third IGBP Congress will be held in Banff, Canada, and include Working Group discussions that will form a very important part of the Congress. They will be carried out in parallel on integrative topics and on issues of between projects. A Working Group “Global and regional vulnerability to changing fire regimes” (C1) will be co-chaired by:

Co-Chairs: Diogenes Alves, Departmento de Processamento de Imagens, Instituto Nacional de Pesquisas Espaciais, São José dos Campos, SP, Brazil

Sandra Lavorel, Laboratoire d’Ecologie Alpine, CNRS, Université Joseph Fourier, Grenoble, France

C1 Summary of intent :

The objective of this session is to produce an implementation strategy for integrated fire research in IGBP II. Fires are an intrinsic part of the dynamics of the Earth System. Fire regimes result from the interaction between biophysical factors and human land use, with varying weights across biomes and through time. Therefore exposure and susceptibility to fire can evolve as climate and land use change. Fire impacts range across all scales from local to global, can be highly nonlinear, potentially affect all compartments of the Earth System, and can have critical feedbacks to ecosystem goods and services and to human systems. Fire research therefore requires an integrated approach across different IGBP projects, which brings together human scientists, terrestrial ecologists, paleoecologists, and atmospheric scientists to tackle the complexity of interactions that are involved. Critical questions regard: (1) the drivers and patterns of regional and global fire regimes, (2) fire-atmosphere-climate feedbacks, and (3) fire-ecosystem services-human systems feedbacks. To address these a first step is to assemble global and regional data for fire-model development and testing. In parallel with this effort, quantitative knowledge gained across IGBP projects and related research worldwide needs to be synthesised on impacts of changes in fire regimes on a range of ecosystem services. These elements should ultimately help us to quantify the vulnerability of different systems and regions, and of the Earth System, to global change scenarios.
