EU call for proposals
  • European ecosystems linked to global change
  • Impact on distribution and transmission of
    pathogens
  • Models to predict dispersal and transmission
  • Surveillance and modeling for early warning

EDEN integrated project
WP8 Training, Dissemination, Management
Coordination
For each indicator disease, field studies are
conducted to understand patterns and
processes WP1 Landscapes/biotopes WP2

Correlations between socio-economic factors and
increases in TBE incidence across CEE countries
  • Shift from correlations in time to correlations
    in space
  • - substantiates causality

Climate change and emerging tick-borne infections
  • Evidence for the impact of the following on
    tick-borne diseases
  • Human-induced abiotic environmental changes
  • Human-induced biotic environmental changes
  • Changes in human behaviour induced by
    socio-economic factors
  • By chance, acted synergistically on living
    conditions of all partners
  • Virus, ticks, wildlife, humans
  • Enhanced - zoonotic risk of infection
  • - exposure of humans to risk
  • Unforeseen consequences of end of Soviet
    rule

end of the cold war
political global warming
Human activities, driven by a wide variety of
factors, are crucially important in the emergence
of ZOONotic diseases
17
Landscape and disease transmission
Hantavirus and Lyme borreliosis infections in
Belgium
  • remote forest areas
  • low incomes
  • Outdoor work
  • wealthy areas
  • forested periurban zones
  • Recreational activities

Mythology vs. science
(the) totalitarian ambition of the savage mind
is quite different from the procedures of
scientific thinking It is a way of thinking
which must imply that if you don't understand
everything, you don't explain anything.
