On 17 June 2025, the third AMAREX stakeholder workshop took place in Berlin. It marked the final local stakeholder event in Berlin as the AMAREX project approached its conclusion. The workshop brought together a diverse group of planners, city officials, researchers, and practitioners to test and discuss the project’s latest tool developments for urban rainwater management in the context of climate extremes.

Presenting the AMAREX Web Tool Prototype

During the workshop, participants explored the final prototype of the AMAREX web tool, developed for Berlin and Cologne. The tool is designed to help municipalities prepare for extreme weather events by assessing how decentralized rainwater management measures affect the urban water balance. In doing so, it supports climate-informed planning and integrates water-sensitive strategies into the early stages of urban development.

Testing Practical Tools for Drought and Heavy Rain

Participants also engaged in a hands-on session to test two Excel-based tools developed within AMAREX – one focusing on heavy rainfall events and the other on drought resilience. These tools are intended to support municipal planners and water managers in evaluating site-specific risks and opportunities for decentralized rainwater management measures. Constructive feedback from the session fed into final improvements.

AMAREX: Adaptation of Rainwater Management to Extreme Events

The workshop was part of the AMAREX project, funded by the German Federal Ministry of Education and Research (BMBF). The project promoted practical approaches to address flooding and water scarcity in cities by developing climate-resilient urban planning through digital tools and blue-green infrastructure.

Accessing the Tools

All workshop materials and tools are available online:

• AMAREX Web Tool (with Excel downloads on heavy rainfall and drought)
