The "Warming Stripes" show the possible temperature development in Dresden from 1961 to 2100. Each coloured line stands for the average temperature of one year. The darker the red, the higher the annual mean temperature calculated on the basis of climate models. The trend is clearly visible: It is getting warmer! (Calculation/Graphic: V. Maleska/IOER)

Research on Climate Change

The "Warming Stripes" for Dresden show it clearly: Climate change is also in full swing on our doorstep. The IOER is engaged in the field of climate change - permanently with its research and on various occasions with special actions and formats of knowledge transfer. - Here we provide information on our contributions.

Mobile exhibition shows good examples of heat adaptation in cities

The extreme summers of 2018 and 2019 have shown: Heat can already become a problem in German cities. In addition, extreme heat events will occur even more frequently in the future. In many places, however, there are also interesting ideas for adapting to summer heat in densely built-up urban districts. The team of research project HeatResilientCity has compiled some good examples into the exhibition "A city cools down - Together for a better quality of life in summer".

Looking at climate change and its consequences

IOER researches on heat, heavy rain and other environmental risks

Progressive climate change is characterised by increasingly frequent weather extremes. These include heavy rainfall events as well as long heat waves and drought in summer. How do we meet these challenges? How can we prevent and minimise damage? What can we learn from others?

These research projects are looking for answers:

HUeBro - Elevated housing in areas prone to flooding using the Elbe village of Brockwitz as an example
Lifting houses instead of building a dyke? Could that be a new type of flood protection? A feasibility study in in the Saxon village of Brockwitz on the Elbe river was convincing There, house lifting is now being implemented as a model. Other locations may also benefit from this.

RAINMAN - Integrated Heavy Rain Risk Management
The RAINMAN project developed innovative methods and new tools to support municipalities and regions to cope with the hazards of heavy rain and to mitigate heavy rain risks as far as possible. These management tools and methods were put together in the RAINMAN-Toolbox, an information platform for municipalities and further local and regional stakeholders.

STRIMA II - Saxon-Czech Flood Risk Management II
Floods do not stop at national borders. This makes cross-border cooperation all the more important – during the event of a crisis, but also in risk prevention. The project promotes cooperation in flood risk management between Saxony and the Czech Republic.

GewässerKlima - Development of the ecological quality of surface waters in the face of climate change
In future, extreme events such as floods, heavy rainfall or long dry periods with high temperatures will affect the sensitive ecological balance of streams, rivers and lakes. This has consequences for flora and fauna, but also for drinking water. Are we well enough prepared? Or do we need to adapt instruments for water management?

HeatResilientCity – Heat resilient development of cities and urban districts
Prolonged heatwaves are becoming a challenge for urban development. Redesigning open spaces, adapting the structures of residential buildings, and combining different measures can make it possible to maintain the quality of life in densely populated urban neighbourhoods. The HeatResilientCity project is also addressing the population’s experience of heat.

IOER investigates positive effects of urban greenery

Especially in densely built-up cities, it is becoming increasingly important to ensure that there is sufficient green space. It helps to mitigate the impacts of climate change. Green spaces provide space for water retention during heavy rainfall and flooding. They regulate urban climate in the heat of summer, and people get the opportunity to recover. The following projects investigate how green spaces in cities can be better protected and developed.

SALUTE4CE - Integrated environmental management of SmAL Green Spots in FUncTional Urban ArEas
The project examines how cities can integrate small green spaces into their environmental management and thus achieve much for the urban climate and biodiversity. It is based on the concept of urban environmental acupuncture.

UrbanNBS - Urban Green Structures for Biodiversity – Integrated Strategies and Measures towards the Protection and Fostering of Biodiversity in Cities
The aim of the UrbanNBS project is to preserve and strengthen the diversity of habitats, plants and animals in the interior of cities as well. Green spaces, which are permanently secured by municipalities, are also important for regulating the urban climate.

The IOER considers economic aspects of climate change

Efforts to protect the climate have an economic dimension, too. What are the adjustment screws? This is another question that the IOER and its research partners are exploring. The results are published as policy papers, statements or guest articles in the media. Here are two examples (both only available in German):

The IOER offers interactive information services

When the climate changes, urban greenery becomes more and more important. The IOER has developed various information services. They help to better find and access green spaces in a city like Dresden - even the small and hidden ones. They also inform about the manifold services that urban nature provides in the context of climate change. (Both services are only available in German.)
