| Zusammenfassung |
| Landscape fires show large variability in the amount of biomass or fuel
consumed per unit area burned. Fuel consumption (FC) depends on the biomass
available to burn and the fraction of the biomass that is actually combusted,
and can be combined with estimates of area burned to assess emissions. While
burned area can be detected from space and estimates are becoming more
reliable due to improved algorithms and sensors, FC is usually modeled or
taken selectively from the literature. We compiled the peer-reviewed
literature on FC for various biomes and fuel categories to understand FC and
its variability better, and to provide a database that can be used to
constrain biogeochemical models with fire modules. We compiled in total 77
studies covering 11 biomes including savanna (15 studies, average FC of
4.6 t DM (dry matter) ha−1 with a standard deviation of 2.2), tropical
forest (n = 19, FC = 126 ± 77), temperate forest (n = 12,
FC = 58 ± 72), boreal forest (n = 16, FC = 35 ± 24),
pasture (n = 4, FC = 28 ± 9.3), shifting cultivation (n = 2,
FC = 23, with a range of 4.0–43), crop residue (n = 4,
FC = 6.5 ± 9.0), chaparral (n = 3, FC = 27 ± 19),
tropical peatland (n = 4, FC = 314 ± 196), boreal peatland
(n = 2, FC = 42 [42–43]), and tundra (n = 1, FC = 40). Within
biomes the regional variability in the number of measurements was sometimes
large, with e.g. only three measurement locations in boreal Russia and 35
sites in North America. Substantial regional differences in FC were found
within the defined biomes: for example, FC of temperate pine forests in the
USA was 37% lower than Australian forests dominated by eucalypt trees.
Besides showing the differences between biomes, FC estimates were also
grouped into different fuel classes. Our results highlight the large
variability in FC, not only between biomes but also within biomes and fuel
classes. This implies that substantial uncertainties are associated with
using biome-averaged values to represent FC for whole biomes. Comparing the
compiled FC values with co-located Global Fire Emissions Database version 3
(GFED3) FC indicates that modeling studies that aim to represent variability
in FC also within biomes, still require improvements as they have
difficulty in representing the dynamics governing FC. |
