For the 2017 group of International Climate Protection fellows, the mid-term study tour is ongoing. This year, the fellows get some rather deep glimpses into renewable energy technologies during a two-day workshop at the Renewables Academy (RENAC) in Berlin.
At the same time, five CIPSEM alumni meet during the selection conference for the next cohort of ICP fellows.
Who is recognizing them? Best wishes to all of you!
While the Short Course on Ecosystem Management is going on, we could also welcome the International Climate Protection Fellows in Dresden. To supplement their research stay in Germany, we organize a 2-week study tour (Learn more about the program and the partners involved).
At the beginning of the tour, we have been welcomed in the Dresden town hall by Deputy Mayor Ms. Eva Jähnigen, in charge of environment and communal services, and Ms. Ina Helzig, Head of the municipal climate protection office. We got to discuss the role of municipalities when it comes to mitigating climate change and to adapt to a changed climate.
Ms. Jähnigen and Ms. Helzig have introduced us to the climate protection activities in the city of Dresden.
Measures taken by the city are soft, based on incentives and awareness raising.
Germany is not on track regarding its greenhouse gas emission reduction goals. What cities can do to mitigate climate change, and also to adapt, has been discussed intensively.
Dresden is in the comfortable situation to own its power plant as well as an extensive district heating network.
There are plans to include solarthermal energy in the district heating network. This would help to reduce greenhouse gas emissions.
The city and several partners including active citizens promotes the use of climate friendly transportation, for example through advertisement campaigns and in the European Mobility week.
The links between air quality and climate change have also been discussed.

We have also paid a visit to the Leibniz Institute for Ecological Urban and Regional Development, IOER. There we have been introduced to an extensive study on climate change in the region of Dresden. We have learned how the climate is likely to develop, and which measures the scientific community recommends to reduce negative impacts and use opportunities. It has been helpful to learn from the project coordinators how different scientific groups and stakeholders have been involved so that meaningful products could be developed. We also have been offered some glimpses into the current understanding of transformation science and different types of involvements of science in real-life issues.
The day after, everybody took on an out-of-the-ordinary role while enacting a conflict on the utilisation of water resources and infrastructure development in the context of the Bolivian Andes.
The group also got to explore the forest botanical garden and has learned from the staff of the Saxon state forest service how the uncertainty of climate change is being approached in forest management.
The day ended with an immersion into German and European culture. After a stroll through the Dresden Zwinger we have attended the amazing ballet Manon in Semper Opera.
On Saturday, many have participated in a guided tour, along with the fellows of the UNEP/UNESCO/BMUB short course on ecosystem management.
We are enjoying summer while it lasts. Today we had a barbecue with both the participants of the Ecosystem Management short course and participants and facilitators of the INOWAS summer school on managed aquifer recharge. It has been good to recharge the batteries after a long day of excursion and classes and a nice opportunity to get to know each other (better) … and also to witness so many barbecue styles.
During the past two weeks, CIPSEM alumna Olujumoke Adesola Ogunrayi has been living again in one of the CIPSEM apartments. She returned to Dresden to attend the International Synthesis Summerschool on Network functional dynamics – Technological, Human & Ecological Dimensions. We were happy to see her as enthusiastic as ever… and to learn that her 2014 final paper has evolved into a sound publication. Congratulations and keep up the good work at the Ondo State Ministry of Environment in Nigeria.

Two years later, a publication based on her final paper project has come out.
“Stadt der Moderne” (City of Modernity) is the title that Saxony’s third largest city uses to describe itself. In terms of its energy concept, this rings true to us. In 2015, the municipality has received the European Energy Award in Gold. During our excursion today we got to meet some main actors contributing to this sucess: employees of the city administration as well as Dr. Schwenk of FASA AG. The company earns most of its money with noise cancelling infrastructure, but is also passionate about offering affordable buildings equipped with solarthermal heating.
Please see the image captions for details.
Mr. Braumann works on energy management for the city of Chemnitz. He has introduced us to a municipal, energy efficient kindergarten building which is heated by cloud computing servers.
After Mr. Zichner from Chemnitz’s environment office has introduced us to the energy-related activities of the city, Dr. Schenk of FASA AG outlines the solar-thermal building concept employed by the company.
We get to see refurbished houses dating back to 1904.

Not far away, a complete solarthermal district is being established.
We get to see various stages of construction an can ask tons of questions to the endlessly patient Dr. Schwenk.
During our excursion to the Altenberg Area of the Ore Mountains, the interlinkages of environmental issues becomes – once again – very clear. We have learned about the high concentrations of air pollutants such as Sulfur Dioxide in the area during the end of the 20th century to a large extend brought about by the burning of lignite rich in sulfur in the power plants of the German Democratic Republic as well as the CSSR and facilitated by the topographic conditions. Transboundary impacts of such unmitigated air pollution have been noticed to such an extend in many terrestrial and aquatic ecosystems throughout Europe that led to the UN-ECE Convention on Long Range Transboundary Air Pollution in 1979. With that went the establishment of an international monitoring programme for the impacts of air pollution on forests. The long-term monitoring site close to Altenberg operated by the Saxon State Public Enterprise Sachsenforst is part of this network.
Our group is being welcomed by Dr. Henning Andreae of the Saxon State Forest Enterprise. You will guess from the picture that mornings in the Ore Mountains are more chilly than in Dresden 😉
Dr. Andreae and the local sampling expert explain the motivation and framework for the forest condition monitoring scheme, and also shed light on the sampling procedure and results.
Sampling soil solution from different depths – how does this work?
We also get to see the nearby meteorological measurement site and location for measuring concentrations of various atmospheric pollutants as they would impact the top of the forest canopy.
This is how tiny the passive samplers are!
In the end, we have a short hike to Kahleberg (‘the bare mountain’). Where there had been serious forest die-back during the 1980s and early 1990, young trees look quite healthy.
The high atmospheric inputs of sulfur still have an impact on soil chemistry and the chemical composition of the run-off from this area. Thanks to abatement of sulfur emissions during the 1990s, forests are recovering as we could see during a short hike to Mount Kahleberg. This shows that positive changes are possible. This confidence and determination is needed as issues such as NOx-emissions, Ozone concentrations, persistent organic pollutants, interdependencies with climate change mitigation and other challenges still require a lot of attention, as has been outlined in the latest air quality assessment report of the UN-ECE.
Thanks to Dr. Henning Andreae of Sachsenforst for sharing some of his insights with us.
During an excursion to the soil treatment facility of the Bauer Resources GmbH we learned what can be done if prevention has failed and in-situ treatment of polluted soil is not an option – and at which cost.
See the image captions for details.
We meet with Dr. Uwe Schlenker of Bauer Resources GmbH and Dr. Axel Fischer (TU Dresden).
Dr. Schlenker, a CIPSEM alumnus, explains how a former pig farm has been transformed into a soil treatment facility.
He answers a long series of questions about how different kinds of soil pollutions can be treated in-situ and ex-situ, in this treatment facility.
After optimising our outfits towards maximising visibility and lowering the risk for spreading pollutants, we set out for a tour of the premises.
This is one of the halls in which soil bacteria are provided good conditions (through regulation of aeration and temperature as well as addition of nutrients) for multiplying and breaking down pollutants.
Activated carbon, mainly from coconut shells, is for example used to treat emissions from the ventilation system of the facility.
The soil is partially being processed by machines and techniques used in composting plants.
Some of the processing is also done outdoors, on a sealed surface. All the run-off from this area is being collected and treated.
Dr. Schlenker activates the installation which cleans the wheels of lorries leaving the treatment facility.
The treated soil can be used for construction, not for food production.
