Some Recent Scientific Accomplishments in Observing
and Understanding Changes in Land Cover and in Terrestrial and Marine
- Long term experiments at specific locations suggest that soil carbon
losses from intensive farming systems can be reversed through changes in
farming technology, such as reduced tillage systems and the use of cover crops
and manure amendments to increase soil carbon levels and enhance soil
- New analyses using satellite data from the Amazon rain forest suggest that
as much as 30% of the deforested land is in some stage of secondary
succession. These regrowing systems are potentially important sinks for
atmospheric carbon dioxide.
- Satellite observations of fires in the southern African savannas are
providing new information on the rate and spatial distribution of biomass
burning in this region. This research suggests that earlier biomass burning
estimates are too high.
