Toward Development of Japan’s Green Infrastructure

Ecosystem-based Solution for Disaster Risk Reduction, Infrastructure Development, and National Land Management

2015/02/20

In recent years, attention has been paid in countries outside Japan to a new concept, green infrastructure, within various fields of government administration for tasks such as environmental protection, disaster prevention and mitigation, enhancement of urban functions, and promotion of rural development. Green infrastructure policy is thought to involve infrastructure development, disaster prevention and mitigation, and national land management intended to take advantage of the power and mechanisms of the natural environment. Europe and the United States have been using the concept of green infrastructure in government documents and have been increasingly implementing policies and programs that add new value to existing infrastructure. By contrast, in Japan, the role of green infrastructure is not currently defined in government documents. However, the concept could potentially be an effective approach to solving various social issues in Japan, including increased disaster risk, a population that is both aging and declining in number, stagnant regional economies, and deterioration of the natural environment. With regard to the form of green infrastructure for Japan, it will be necessary to take advantage of the multi-functionality and regional uniqueness of green infrastructure, which are its most important characteristics, while ensuring consistency with international views and giving consideration to social situations and the natural environment in Japan. We hope that based on these ideas, the Japanese government will implement policies and programs related to green infrastructure in cooperation with companies, universities, and civic groups as a step toward solving social issues in Japan.
