Tokyo Waterworks has installed around 3,800 birdhouses in water conservation forests. This aims to encourage nestbuilding by wild birds, which eat harmful insects, thereby decreasing damage from those insects to the trees that make up the water conservation forests. In other words, the activity endeavors to resolve problems by utilizing the power of nature, since insect control using pesticides is unsuitable in water conservation forests that serve as the source of people’s drinking water. This can be called a nature-based solutions (NbS).
Ogouchi Dam is a reservoir for water flowing from water conservation forests and can be considered gray infrastructure, while water conservation forests that function to maintain a low sedimentation rate for the dam can be called green infrastructure. The combination of the two is likely to receive more and more attention going forward as a method of global environmental conservation.
This means that water conservation forests not only secure tap water and preserve biodiversity, but also help to combat climate change by absorbing CO2 through the trees that grow in them, and thus they are related to multiple SDGs.
CASIO Forest promotes greater understanding of the importance of these issues thanks to the hard work of participating employee volunteers. To contribute to the resolution of global environmental issues, Casio will continue promoting these activities to create opportunities for employees to think about what the company can do for biodiversity in its business activities.
