A thriving beaver population is threatening the stability of the Netherlands' sea defences. The Mammal Society has brought together other wildlife groups to work out how to protect these important water-blocking dykes from the small but potentially destructive semi-aquatic rodents. Beavers play an important ecological role in the Netherlands and were initially brought in to increase biodiversity. The beaver-breeding program began in 1988, and since then the beaver population has grown exponentially. There are now an estimated 700 beavers residing in the country's streams and canals. Triumphant mating habits combined with the beavers' ability to breed so successfully in the Dutch countryside mean they have been moving beyond the southern province of Limburg and entering towns and cities that may not be prepared for the influx. With the Dutch beaver population expected to hit around 7,000 by 2032, the need to take pre-emptive action is now a very important theme.

The University Campus in Berlin-Adlershof is well known for the many research institutions present in its area. One of those is the HZB Helmholtz - Zentrum Berlin, where a prototype of a linear accelerator with energy recovery is placed. In this building, electrons are accelerated to almost the speed of light using a great deal of energy. After passing through a high-speed path, the electrons are to be recaptured in bERLinPro and their energy recovered. Therefore the hall is protected by a reinforced soil structure made with the wrap-around system. In the last times, some foxes started to dig and excavate tunnels inside the embankment, creating some instability problems.

The busy Inntal motorway from Arlberg towards Innsbruck is a very important west-east connection. For the construction of a new gallery below steep rock faces, ASFINAG has planned 3000 kJ rockfall protection nets. These barriers will protect the construction site and the motorway during construction.
