Nature-based solutions such as Natural Water Retention Measures (NWRM) are promising options to mitigate flood risks as a complement to grey infrastructure. These types of measures not only serve to reduce risk, they also provide additional ecosystem services including increased biodiversity and recreation opportunities. However, a common characteristic of green infrastructure measures is that they often claim more land than traditional methods.

The reconciliation of flood risk management and land management is needed. Since all NWRM primarily need to be implemented on private land the consideration of multiple aspects includes: economic issues (e.g. how to compensate for or incentivize flood retention services); property rights issues (e.g. how to allow temporary flood storage on private land); issues of public participation (e.g. how to ensure the involvement of private landowners) as well as issues of public subsidies (e.g. how to integrate/mainstream flood retention in agricultural subsidies). LAND4FLOOD cost action aims to address these different aspects and to establish a common knowledge base and channels of communication among scientists, regulators, land owners and other stakeholders in field.

Within the EU COST Acton project LAND4FLOODS – Natural Flood Retention on Private Land –  publications,  workshops and other dissemination and network activities are funded.  The European project ist starting in September 2017 and runs fire four years. The COST activities are vindicated by Lenka Slavikova (J.E.P. University Usti nad Labem, CZ) and Thomas Hartmann (Utrecht University, NL). The project is organized in  various working groups. LAND4FLOODS  is in principle an open network of academics and practitioners doing research. More information on the programme and the content of this project can be found on the COST website.
