MuT KliWa - Mobility and tourism in times of climate change in the city of Nuremberg and in Tegernsee valley | Umweltbundesamt

Identification of affected regionss through Status Quo Analysis:
Existing studies have already shown that there are overlaps and synergies in the area of climate change in the areas of transport and tourism, but here the areas were treated separately. Both industries expect risks due to a further increase in the average annual temperature, the increase of heat days or the intensification of extreme weather events. Examples include health problems for tourists, drivers and passengers on hot days (such as cardiovascular problems), with the consequence that public transport and leisure activities are avoided in hot periods. At the same time, however, both sectors see economic opportunities due to the growing environmental awareness of the population or the development of new (climate) adapted offers and business models. This initial situation forms a promising basis for the joint development of measures that will improve the future viability of the two sectors in Nuremberg and the Tegernsee valley and their resilience to the consequences of climate change.

City of Nuremberg:
Based on the results of the DANUBIA simulation tool, the average summer temperature (May to October) in Nuremberg will increase from an average of 14 ° C in the reference period 1971 to 2000 to 17 ° C by 2060. The climatic changes are even more evident in the average number of heat days per year. It will double in Nuremberg to 30 days until 2060 to 25. Looking at the winter months, the frost days are the equivalent of the heat days. In Nuremberg in the comparative period from 1971 to 2000 there were on average 90 to 100 frost days per year. By the year 2060, the number of frost days will fall to 60 to 70 days. The mean snow cover duration will change as well. In Nuremberg, it will shorten to 21 to 30 days. Finally, the total precipitation is expected to drop slightly by up to 50 mm - there are seasonal shifts, i. E. drier summers, but wetter winters.

Tegernsee Valley:
Application of the climate scenario REMO regional:
For Tegernsee valley, the simulation tool DANUBIA indicates a temperature increase for the summer. Thus, by the year 2060, the average summer temperature (May to October) will increase from 12 ° C to 14 ° C. This climatic change becomes even clearer with the average number of heat days per year. In the Tegernsee valley there were only up to two heat days annually in the past. By 2060, eight to ten heat days are expected. Looking at the winter months, the number of frost days in the comparative period from 1971 to 2000 averaged 200 to 250 days. By the year 2060, there will only be 90 to 100 frost days per year. The mean snow cover duration will be shortened. In the past comparative period, for example, there were 101 to 120 days with snow cover closed. By the year 2060 average snow cover duration of 41 to 50 days is expected. Looking at the annual rainfall totals, the Tegernsee Valley is expected to show a mean decline of 200 to 150 mm, with a greater decline in the summer than the increase in winter.

Opportunities and risks of climate change in regions of the city of Nuremberg and the Tegernsee valley are presented for both urban and rural areas.

Based on the identified risks and opportunities, a checklist for the assessment and a selection of adaptation measures were created and evaluated, so-called "lighthouse ideas". On this basis, an economic-ecological assessment was then carried out.

A selection of measures:

• Getting around with the velotaxi, e-bike, green oases of peace for deceleration
• Solar kiosk (combination of solar charging station, tourist info point, the sale of refreshments and a shady space under solar panels for refueling for body, smartphone and e-bike)
• Flexible combined offers of transport and tourism providers: "Mobility Plus"

Lighthouse Ideas for adaptation:

Tegernsee Valley:

I. Offer Feed "Always a suitable idea"

• Information platform for daily up-to-date tourist and commercial offer on a digital basis
• Alternatives to weather changes are displayed
• Display according to weather, age and interest

II. Driving M.i.T. (Mobile in the valley)

• Infer gaps in a mobility chain to the destination through feeder systems
• Offer of mix in mobility choices regardless of weather conditions

City of Nuremberg:

I. Mountain Road 2030

• Road serves as a cool path through the old town
