Frequently asked questions
Sponge (Upstream-Downstream Solidarity and Partnership for Nature-based Adaptation and Governance in Cross-Border River Basins) is an international project within Interreg Meuse-Rhine, running from October 2025 to September 2028.
Within this project, partners from the Netherlands, Belgium and Germany work together on measures to address drought and flooding in the Euregio Meuse-Rhine. The project focuses on restoring the natural sponge effect of the landscape, so that rainwater is retained longer and flooding risks are reduced.
A sponge landscape is a landscape that can retain water and release it slowly, like a sponge. Forests, hedges, and grasslands help rainwater slowly soak into the soil. This reduces flooding and replenishes groundwater during dry periods. Due to deforestation, drainage, and construction, this balance has been disrupted, increasing the risk of both flooding and water scarcity.
Sponge operates in the Euregio Meuse-Rhine, in the border region around cities such as Maastricht, Liège, Aachen, and Hasselt. Partners from the Netherlands, Belgium, and Germany work together on landscape-scale solutions. Because water does not stop at borders, cooperation across the whole region is essential.

Sponge is open to any legal entity in the Euregio Meuse-Rhine. That means not only landowners, farmers, agricultural organisations and nature organisations can submit an idea, but equally municipalities, water authorities and provinces, land-managing organisations and landscape parks, as well as businesses, knowledge institutions and civil society organisations. The one firm condition is that the project is located within the Euregio Meuse-Rhine. Not sure whether your organisation or your idea qualifies? Take the pre-check or get in touch and we will look at it with you.
Sponge provides financial support for local initiatives. The voucher covers 50% of the project budget; the applicant contributes the other 50%, of which at least 20% must come from their own resources or in-kind contributions. In the Netherlands, the Province of Limburg and the water authority add a further 30%, bringing co-financing there up to 80%. Think of planting hedges and trees, creating swales, or reorganising plots so that water is retained longer and drains away more slowly. Alongside funding, Sponge offers practical guidance, access to proven solutions and the backing of a strong Euregional network.
