Scaling Nature-Based Water Management to Prevent Flood and Drought Financial Losses

environmentPilotedTRL 6

Imagine the ground acting like a giant sponge that soaks up heavy rain and lets it out slowly during dry spells. Instead of letting water rush away and cause floods, this project redesigns landscapes to hold onto water naturally. It's like upgrading a city's drainage from a simple pipe to a smart, living system that protects the land.

The business problem

What needed solving

European regions face massive financial losses from river flooding and droughts. Current water management is too slow to adapt, leaving landscapes unable to retain water effectively.

The solution

What was built

The project creates practical sponge measures, long-term landscape strategies, action plans, and roadmaps for water retention.

Business applications

Who can put this to work

Civil Engineering
SME
Target: Urban drainage and landscaping firm

If you are a landscaping firm dealing with urban flooding—this project developed practical sponge measures that improve water retention. By applying these nature-based solutions, you can offer clients a way to reduce the risk of river flooding damages which cost €7.6 billion annually.

Agriculture
enterprise
Target: Large-scale farm management company

If you are a farm manager dealing with drought-induced crop losses—this project developed strategies for enhancing groundwater and soil water systems. This helps maintain soil moisture and protects against the €9 billion in annual drought-induced losses.

Insurance
mid-size
Target: Environmental risk assessment firm

If you are a risk assessor dealing with climate-related property damage—this project developed socio-economic appraisals and roadmaps for sponge landscapes. This allows you to better predict and mitigate the financial impact of extreme water events in river basins.

Frequently asked

Quick answers

What is the cost of implementing these measures?

Based on available project data, the project focuses on demonstrating 'economically feasible' approaches, but specific unit costs for implementation are not provided.

Can this be scaled to an industrial level?

Yes, the project specifically aims to 'upscale' sponge measures and demonstrates them in three large river basins (Pinios, Lèze, and Vecht) to create regional scale strategies.

How is the IP or licensing handled?

Based on available project data, there is no mention of specific patents or licensing agreements; the focus is on the dissemination of best practices and roadmaps.

What is the timeline for seeing results?

The project runs from 2024-09-01 to 2028-08-31, suggesting a four-year window for demonstration and validation of the strategies.

How does this integrate with existing water management?

It integrates by evaluating existing sponge measures and implementing new ones within interconnected groundwater, soil, and surface water systems.

Consortium

Who built it

The consortium is highly diverse with 28 partners across 6 countries. While it is research-heavy (9 university and research entities), it includes 3 industry partners and 4 SMEs, indicating a strong push toward practical application. The presence of 16 'Other' partners suggests significant involvement from regional authorities and land managers, which is critical for the regional-scale deployment of water management solutions.
