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).
