The case study will focus on the port of Hamburg and the port of Mannheim, and actors using the ports.

Case 3

Status report, October 2021

 

Case content Introduction

The case study focuses on the Rhine port of Mannheim and the surrounding metropolitan region, and actors using the port. The port of Mannheim is one of the most important and largest inland ports in Europe, and is home to numerous large companies in sectors such as energy, chemicals and pharmaceuticals.

By the end of 2020, the Mannheim part of the study has reached a first milestone. Two impact chain workshops have been conducted as participative online events. One workshop investigated the risk of extended periods of heat on the population of Mannheim and vulnerable groups. Stakeholders have been the professional firefighters of Mannheim and several offices of the City of Mannheim municipality. The second impact chain workshop was a multi-threat, multi-stakeholder workshop. The participants investigated the risk of more frequent and longer summer periods of drought and low water of the river Rhine on the infrastructure of Mannheim. The Mannheim port authority, the Mannheim large fossile power plant, a logistics company, a company producing products based on pulp, and the City of Mannheim contributed to creating a qualitative impact chain. In both cases, the starting point was the German national set of general impact chains as published in 2016. For the Mannheim cases, the relevant parts have been selected and then refined.  The on-going next step of the case study is performing further quantitative analyses. For this purpose, one stakeholder has provided data for jointly selected indicators for risk elements of the aforementioned impact chains. This data is currently employed for creating a risk matrix for assessing the impact on low waters of the Rhine on the freight rates. The risk matrix can be used to explore scenarios of more frequent and longer periods of low waters in the near future and their impact on transport costs (inland waterway transport relation Rotterdam - Mannheim). 

Case content

Investigating environmental and economic effects of repeated long periods of heat, drought and of low water of the river Rhine, Europes most important inland waterway. Assessing the risk, the potential damages, the potential cost of damages and the potential cost of adaptation measures to infrastructure and industry in a heavily industrialised metropolitan area at the Rhine (power generation, inland water transport, supply chains, etc.). Further developing IC methods for creating a basis for assessing potential cascading effects. The case has transborder aspects.

Research Innovations

Improved methods for analysing cascading impacts of climate-related hazards based on regional risk and dependencies Improved assessment of economic consequences based on resilience assessment of companies Methodological basis for assessing potential cascading effects Connecting national, regional, and stakeholder specific risk assessment.

Study areas

Environmental and economic effects of repeated long periods of drought and of low water of the river Rhine. Assessing the risk, the potential damages, the potential cost of damages and the potential cost of adaptation measures to infrastructure and industry in a heavily industrialised metropolitan area at the Rhine (power generation, inland water transport, supply chains, etc.).

Stakeholders involved

Industrial and public stakeholders in a heavily industrialised area at the river Rhine (Mannheim metropolitan area, Rhine-Neckar harbour, city of Mannheim, energy supplier, logistics company, maker of paper-based products).

Summary data collection

Mix of existing data, freely available data (climate, forecasts, economic data), local data of stakeholders (partially private).

Expected results

1) Added value for stakeholders:
a) better understanding of the risk of extended periods of low water of a major European / German inland waterway on the supply chains based on the inland harbours on the Rhine and ARA seaports and on the regional infrastructure and industry
b) better understanding of the risk of extended periods of drought, heat, and low waters of the Rhine to the population and community facilities of a metropolitan region along the Rhine River

2) Methodological improvements: improved consequence analysis, improved cascading effects analysis, connecting Impact Chains with more general risk analysis methods

3) Good practices in stakeholder training, co-production of knowledge, and presentation of results
