Impact of Heat in Cities: Household Surveys in Bonn

Just in time for the summer temperatures, the University of the United Nations is conducting a study on urban heat. Since May 10, 2018, scientists have questioned households in the city center and Bad Godesberg.

Heavy rains, storms or heat waves – for some years now there has been a growing debate about such extreme events in the context of climate change. Although the climate in Germany is relatively cool, the heat waves increase. These often have a negative impact in particular on the urban population. According to information from the Federal Ministry of the Environment, Nature Conservation and Nuclear Safety, for example, the heatwave in 2003 caused around 7,000 deaths. In addition, there have been numerous illnesses caused by the heat, such as dehydration, heat stroke or cardiovascular disease.

Since heat waves can become a problem, especially in densely populated urban areas, cities have to find ways to adapt and protect their inhabitants. An interdisciplinary research team has now taken on this topic and launched the research project ZURES. While project partners carry out analyzes and forecasts on the heat load, the experts of the United Nations University devote themselves to the population.

Bonn is a pilot city for their project. The goal is to understand how the urban population in Bonn perceives summer heat, how it can be prepared and what measures can be taken to minimize the exposure to heat. The project takes place in cooperation with the city administration of Bonn.

Since May 10, a team headed by the Institute for Environment and Human Security of the UN University in Bonn is on the way; equipped with tablets to ask as many residents as possible in two regions of Bonn (Inner City / Old Town and Bad Godesberg) about these topics.

ZURES is a research project funded by the Federal Ministry of Education and Research (BMBF), which aims to reduce the impact of heat stress. Within the framework of ZURES, methods and instruments are to be developed in close cooperation with the cities of Bonn and Ludwigsburg, which will allow a better adaptation to heat waves now and in the future. The ZURES consortium headed by the Institute for Spatial Planning and Development Planning at the University of Stuttgart (IREUS) consists of seven partners, including three research institutes, two planning offices and the two partner cities.
