Pan European Erosion Risk Assessment
(PESERA)
Land degradation is widespread in Europe. Yet
its severity, and the areas affected, are poorly
quantified. PESEREA simulates the effects of
climate change on soil erosion risk in contrasting
areas of Europe.
The PESERA concept differs fundamentally from
empirical models such as the USLE and its
derivations; it is runoff-based and estimates
potential monthly erosion at a 1-kilometre
resolution.
Erosion and climate change
The PESERA model was run for a 2071-2080 for
climatic scenario in a northern and a southern
window. Two land uses were considered: current
and all-arable-under-maize. A Hadley Centre
climate change scenario (SRES-A2b) was used
with the original 50 km resolution of the monthly
climatic parameter grids interpolated to a 1 km
grid. Soil erodibility was assessed from the
European Soil Database (v. 1.0), scale 1:1
million.
