This pan-European database functions as a portal to sponge projects and measures from existing water retention databases (see logo’s with information below) and new data that will be collected within the SpongeBoost consortium (www.spongeboost.eu). As a navigation guide it brings European data from different databases together and provides a geographical overview of existing sponge projects and measures. These projects and measures have in common that they aim to restore or enhance landscapes’ natural water retention (or sponge) capacity.

In this guide an overal distinction is made between large-scale projects (e.g. the restoration of large nature reserves) and more local measures (e.g. the creation of small wetlands or pools in between agricultural fields). In case of large-scale projects, generally a pallet of different restoration measures is implemented. In case of local-scale measures, on the other hand, it yields a single type of measure which is often implemented at various localities distributed across a larger area.
