Welcome to the PARADeS project

The PARADeS project aims to contribute towards enhancing Ghana’s national flood disaster risk reduction and management strategy by investigating key mechanisms (drivers, pressure, state, impacts, response), existing flood risk and disaster management, governance-policy, human-water interaction, development of scenarios, action plans and feasible and sustainable measures. This will be carried out using innovative socio-technical and participatory approaches and tools. Read more below.

Upcoming Event:

On the 23rd of November 2023 from 13:00 – 17:00 CET we will have our final PARADeS conference (online). The conference is on “Managing Flood Disaster Risk in Ghana- Findings, Products, and Recommendations”. Please follow this link for further information.

About the PARADeS project

Ghana is one of the countries in West Africa that is most challanged with flood disaster on annual basis leading to devastating impacts on humans, infrastructure, and the economy. In 2017, the country's northern and southern parts experienced devastating floods, which affected over 1 million people. Besides the annual floods, Ghana experienced several flood-related cascading disasters, which destroyed critical infrastructures such as roads, drainage systems, houses, and bridges. To build resilience to flood disaster risk, the PARADeS project aims at strenghtening Ghana's flood disaster risk management (FDRM) through an inclusive participatory approach.

The overall objective of the PARADeS project is to contribute to Ghana’s national flood disaster risk management (FDRM) strategy, thus increasing the country’s resilience to flooding disasters. The project is composed of a combination of research, development, and institutional strengthening activities. It integrates diverse information and data sources and develops collaborative scenarios and socio-technical tools in order to support coherent decision-making processes. A key aspect will be investigating and modeling cascading risk effects regarding critical infrastructure. All processes and working steps are realized in a participatory way together with Ghanaian stakeholders. The end products are strengthening institutional and citizens’ capacity through a series of activities on societal awareness and training of specialists, decision, and policymakers. Technologically, PARADeS will produce a set of decision support tools to effectively disseminate vital information to citizens, researchers, and decisionmakers to alleviate the impact of flooding. This will be demonstrated in three case study areas identified during the definition stage:

1. Accra – urban-runoff and coastal floods
2. Kumasi – urban-runoff and river floods
3. White Volta river basin – river floods

  • Provision of hydrologic, hydrodynamic, and agentbased models to generate new information, which will provide the basis to understand flood risk
  • Assessment of scenario-based flood hazard, vulnerability and risk, and flood hazards impacts on Critical Infrastructure (CI) with cascading disasters
  • Identification of feasible prevention and adaptation measures
  • Assessment of existing institutional settings and networks and policy options for participatory flood risk governance
  • An integrated decision support system (DSS) tool named GaPS-fDSS for FDRM. The GaPS-fDSS consists of the Floodlabel for raising risk awareness and knowledge of prevention and ProMaIDes as a supporting tool for the FD-CRISys DSS to increase decision-makers’ capacity to manage, prevent, and respond to hazards and impacts caused by floods to critical infrastructure systems
  • Strengthen the research and educational capacities of partner institutions, and to further develop the capacity of stakeholders, communities, specialists and practitioners
  • Integration of developed technologies and innovative infrastructures of PARADeS into the institutional systems
  • A concept for a flood risk and disaster prevention
    center in Ghana

Sustainable development of flood disaster risk management (FDRM) needs the understanding and integration of the social, technical, and governance perspectives. Based on intensive stakeholder participation and socio-technical tools the projects’ work packages address these different perspectives and mutually exchange their findings to contribute to the development of sound FDRM measures. The work plan is composed of seven work packages (WP). All WPs are closely interlinked, with results and information passed on between them.

The University of Bonn (U-BN)

The University of Bonn (U-BN), Department of Geography’s research group Eco-hydrology and Water Resources Management of Prof. Evers is the overall coordinator of the project.

The group has experience in the development and implementation of hydrological and hydrodynamic modeling, scenario development, vulnerability assessment, flood disaster risk management (FDRM), and decision support system (DSS). And have a good track record in the engagement and participation of stakeholders on FDRM, participatory modelling and enhancing social learning. The research group is currently involved in several projects related to FRM (BMBF), climate change adaption (BMBF), Human-Water-Research (SfB/DfG) as well as flood risk and health in Accra/Ghana (NRW Fortschrittskolleg).  Click here to know more.

The University of Freiburg (U-FR)

The University of Freiburg (U-FR) professor chair of Forest and Environmental Policy is part of the Faculty of Environment and Natural Resources.

University of Applied Sciences Magdeburg (HS-M)

The research group Flood Risk Management (AG FRM) is part of the Department Water, Environment, Construction and Safety (WUBS) of the University of Applied Sciences in Magdeburg (HS-M).

The group was founded 20018 by Prof. Bachmann who is also the current group leader. Primary goal of our research work is the development of methods and tools that contribute to the improvement of flood protection and support adaptive and sustainable flood risk management. The aim is to develop holistic, interdisciplinary approaches. Hydrology, statistics, hydrodynamics, consequences for economy, critical infrastructures, ecology and people, reliability of structures and the risk analysis itself have to be integrated into approaches and tools. The free software package PROMAIDES which supports a multi-criteria, risk-based evaluation of flood mitigation measures is developed by us. Click here to know more.
