Climate related changes in pollen loads

Many climate change related effects have been discussed that may contribute to new allergen sensitization and more severe allergic respiratory diseases. Especially in cities, there are a high number of people suffering from pollen allergies. Adjuvant factors such as air pollutants have an impact on pollen leading to a higher burden for allergic people in urban areas. In order to adapt to climate change, detailed knowledge about the spatial variability of phenology, pollen season and pollen intensity is required. Investigations along urbanisation gradients (space-for-time approach) can be used to assess the influence of temperature on pollen production. As temperature is expected to increase due to climate change, this approach is used to conclude on future conditions. 

Volumetric pollen traps are used to assess airborne pollen concentration.

The project focusses on the allergenic potential of urban parks.


In consideration of the citizen science approach, we evaluate climate-induced variations of pollen production. Moreover, we investigate pollen exposure, diurnal emission patterns of allergenic plants as well as individual symptoms. We evaluate the appropriateness of urban green spaces / city districts to reduce pollen exposure.The results of the allergernicity of urban green spaces serves to affect the new planting or new design of green spaces.
