According to experts, due to climate change, these threats are increasingly affecting the cities of Germany.



The authors of the study, who conducted the research as part of the Water Management and Environment Initiative in collaboration with the construction materials lobby group, said cities should assess how equipped they are against climate change and extreme weather conditions.



Study author Thomas Schmidt said climate risk analysis is important for cities and municipalities to better assess specific threats. For example, due to drought there may be shortage of drinking water in some places.



Schmidt said the heatwave could also put the elderly and patients with pre-existing health problems at risk.



He said the floods that devastated the Ahr valley in western Germany in 2002 may also occur more frequently in some places.



To address such concerns, Germany's Federal Ministry of Research and Education is funding research projects aimed at strengthening the resilience of cities to the impacts of climate change.
