Subproject 4: Ecosystem based solutions

In this sub-project, natural hazards in the study area are to be analyzed and appropriate solutions developed. This includes identifying risk locations, carrying out hazard analyses and developing nature-based solutions to reduce risk and regenerate damaged ecosystems. Various methods such as GIS analyses, field and laboratory investigations and drone data analysis are used. The results should help to identify risk areas and develop best practice guidelines for risk reduction.

Work package 1: Natural site analysis

Analysis of the main characteristics of the study area in relation to the locally relevant natural hazards. The aim is to identify representative sites for detailed investigations by considering various criteria such as biodiversity loss, mass movements, flash floods and climatic challenges. The analysis is carried out using GIS analyses, field and laboratory investigations and drone data analysis to record temporal dynamics of slopes and vegetation development.

Work package 2: Hazard analysis

All relevant natural and geological hazards are considered at the study area level, while individual hazards are analyzed in detail at the local level. This includes the creation of a hazard index map for the entire study area, whereby the most acute hazards are broken down and visualized regionally. In addition, detailed hazard analyses are carried out at selected locations based on field, laboratory and drone data. Furthermore, endangered ecosystems will be identified and designated.

Work package 3: Nature-based Solutions (NbS)

Development of ecosystem-based solutions for selected sites. The focus here is on nature-based solutions (NbS) for geohazards such as flash floods, with a focus on near-natural measures such as the creation of river ponds to mitigate acute hazards. In addition, afforestation to stabilize and regenerate damaged ecosystems through the development and implementation of appropriate afforestation concepts will be pursued.

Work package 4: Hazard identification

Based on the hazard analyses, risk areas are identified and detailed hazard scenarios are developed for the selected areas. This includes the intersection of the hazard index with settlement development in cooperation with social geography as well as the presentation of the exact hazards for the natural hazards in question in the detailed areas. Furthermore, best-practice guidelines and concepts will be created on the basis of the developed and tested nature-based solutions.
