Scorched Earth millenium map shows 'fire scars'
Date:5/22/2008

A geographer from the University of Leicester has produced for the first time a map of the scorched Earth for every year since the turn of the Millennium.

Dr Kevin Tansey, of the Department of Geography, a leading scientist in an international team, created a visual impression of the fire scars on our planet between 2000 and 2007. The work was funded by the Joint Research Centre of the European Commission.

The map reveals that between 3.5 and 4.5 million km2 of vegetation burns on an annual basis. This is an area equivalent to the European Union (EU27) and larger than the country of India that is burnt every year.

The information is vital for scientists and agencies involved in monitoring global warming, measuring and understanding pollutants in the atmosphere, managing forests and controlling fire and even for predicting future fire occurrence.

The research has been published in the journal Geophysical Research Letters.

Dr Tansey, a Lecturer in Remote Sensing at the University of Leicester, said: We have produced, for the first time, a global data base and map of the occurrence of fire scars covering the period 2000-2007. Prior to this development, data were only available for the year 2000. With seven years of data, it is not possible to determine if there is an increasing trends in the occurrence of fire, but we have significant year-to-year differences, of the order of 20%, in the area that is burnt.

The work was undertaken with colleagues from the Joint Research Centre of the European Commission (Italy) and the Universit catholique de Louvain (Belgium).

This unique data set is in much demand by a large community of scientists interested in climate change, vegetation monitoring, atmospheric chemistry and carbon storage and flows.

We have used the VEGETATION instrument onboard the SPOT European satellite, which collects reflected solar energy from the Earths surface, providing global
