Creating a Biotope for Symbiosis with the Surrounding Environment and Conservation of Biodiversity

Nagoya Works (Owari Asahi Factory) is surrounded by a large number of rice paddies. A river is located to the south of the factory and a forest park to the north, making the area rich in water and green spaces. Having been constructed in an area that was originally rice paddy fields, the factory is mindful of environmental conservation.

Additionally, Aichi Prefecture, where the factory is located, has a unique program called Aichi Mitigation to avoid, minimize, and compensate for the impact on nature caused by land development. Based on this program, we created a biotope on the premises when the factory was constructed to promote symbiosis with the surrounding natural environment.

The factory’s biotope is structured so that water flows from top to bottom between two ponds. In addition, since it is adjacent to a retention pond for storing rainwater, the water flows into the retention pond when the water level in the biotope rises due to heavy rain. Connecting the biotope to the retention pond prevents the proliferation of algae and keeps the water level close to that of a natural wetland. The biotope is surrounded by a fence rather than a wall, and slopes have been created. In addition, we have planted foliage that serves as a habitat for living things on around the site and taken other measures to make it easier for creatures living in the surrounding area to enter and exit the biotope.

So far, several species that appear to have relocated from surrounding areas have been confirmed. Going forward, we will continue to maintain and improve the environment in order to attract rare species endemic to the region, such as the Nagoya Daruma pond frog.
