Optimization of eco-system services of urban forests in compliance with the resilience of critical infrastructures in regard to convective events and adaptation to climate change

The project aim is to generate precise cluster recommendations for the development of an urban forest / city tree population, under consideration of vulnerability of critical infrastructure in context to the city tree management, in order to increase resilience to the highest riskless level of relevant ecosystem services.

With “ELA”-summer storm in June 2014 the City of Essen suffered the most severe storm event since the beginning of records. At least since this major catastrophic event it has become clear that the vulnerability of urban tree population is able to disrupt the complete city infrastructure with substantial risks for urban citizens with dimensions of a civil catastrophic event. Adding up to the short- and medium-term Impacts on critical infrastructure and transport safety, large parts of the urban tree population were damaged in urban forests (1.750 ha) as well as in the city tree population (230.000 trees). Within the context of the already occurring climatic change, accumulation and repetition of comparable intensity with less or even greater spatial extent can be anticipated. The impact of climate change is expected to lead to significant changes in ecosystem services.

The planned project is thus of considerable relevance to urban-, landscape- and forestry planning as well as for the preventive disaster protection of the city administration of Essen. The project thus plays an essential part in the climate adaptation strategy of the city of Essen. The project results are expected to provide important recommendations for a substantial optimisation of the forest and city tree population with regard to its risk reduction in regard to critical infrastructure and traffic safety as well as its resilience and sustainable optimization of its ecosystem services.
