  • DFG - Research Training Group "NatRiskChange"

Welcome to the RTG NatRiskChange

In the wake of changing hydro-climatological, geo-physical and socio-economic conditions the magnitude, frequency and impact of certain types of natural hazards are likely bound to change as well. This is highly of utmost importance for many regions in the world where risks due to natural hazards have to be managed and mitigated and this is where the research training group “Natural hazards and risks in a changing world (NatRiskChange)” aims to foster the scientific knowledge basis. This research training group started on October 1st 2015 and is funded by the Deutsche Forschungsgemeinschaft DFG. The central goal of NatRiskChange is to pursue the development of methods to improve hazard and risk analysis and quantification based on the transient, non-stationary nature of hazards and risks in response to changing natural and anthropogenically altered components of the Earth system. Key scientific aims are the development, testing, and pilot application of studies on identification, quantification (mechanisms) and prediction of transient natural hazards and associated risks.

Defenses of doctoral theses

Irene Crisologo will defend her doctoral thesis on 19 November 2019 at 9:00 a.m. at Campus Golm, Building 14, Room 0.45. The title of her thesis is: "Enhancing the effectiveness of flood early warnings in the Philippines". Everyone interested is invited to witness the defense.

Successful evaluation!

We are happy to announce that our renewal proposal was positively evaluated by DFG! The research training group “Natural hazards and risks in a changing world (NatRiskChange)" will be funded for another 4.5 years as suggested after the on-site evaluation! On 1 April 2020, the new funding period will start with Prof. Annegret Thieken as the new speaker of the RTG and Prof. Axel Bronstert as the co-speaker. We are happy to intensify our external collaborations with the German Weather Service (DWD), the Deutsche Rückversicherung and the Vrije Universiteit Amsterdam. In April 2020, new external partners will join our graduate school: we are looking forward to work with partners from the University of Bern (Switzerland), the University of Grenoble (France), and the University of Natural Resources and Life Science (BOKU) (Vienna, Austria). In October 2021, another 12 new PhD students will enter the graduate school.




Bringing some light into the dark

The former NatRiskChange PhD student Tobias Sieg (project Q4) developed a method for hydro-meteorological hazard damage estimation at seamless spatial scales. This method enables probabilistic object-based damage estimation under the consideration of the associated uncertainties, consistently at all spatial scales. So far, the method was applied and positively validated to a flood event in Germany. The next step is the application of the method to meteorological hazards and possibly compound events. Tobias Sieg wrote a Blog Post about his research he conducted together with scientists from IIASA in Laxenburg.
