Current Research: Effect of agricultural biomass burning and deforestation on the global carbon cycle

Dynamic Global Vegetation Models (DGVMs) are useful tools to study the effects of climate change on the terrestrial biosphere. The consequences of land-use on the biogeochemical cycles are expected to be large and of similar order than the climate change effects alone, generating important feedbacks to the climate system. The LPJmL DGVM (LPJ managed Land) simulates the effects of land-use (e.g. crop growth and harvest) and land-use change (e.g. deforestation) on the terrestrial carbon cycle (Bondeau et al. 2007).

Fires can contribute significantly to the biogeochemical emissions, and are the major disturbing factor that features the dynamic of the natural potential vegetation. On agricultural areas, fires can be human-caused for specific purposes, e.g. to reduce the bulk of wastes. A large uncertainty remains on the fate of crop residues that can be burned, used for animals, left over the field, or ploughed into the soil. The rules for its use vary by region. The same applies to the use of woodfuel, where consumption rates vary strongly for different regions. The slash and burn practice and deforestation are of especially importance in the tropics, where large areas of forests are burned to gain agricultural land.

The aim of the study is to implement fire use related to agriculture and land-use change in the LPJmL model, to evaluate its impacts on the carbon cycle, and to quantify the effects of different land-use policies. Results of this work will potentially allow deriving important implications for policy makers (e.g. Reduced Emissions from Avoided Deforestation and Degradation, REDD).


This project (ESR III) contributes to the science objective 2 (Determine the effects of changing land-use and land cover on climate forcing) of GREENCYCLES. It has links to the projects of Ben (ER 3).
