Utilization of green infrastructure adapted to climate change

The use of green infrastructure is the concept of utilizing the diverse functions of the natural environment to solve various social issues.
"Green" not only means "green / plants", but also refers to the concept of promoting the development of social capital and land use in harmony with the environment in general, such as farmland, rivers, forest areas, rice fields, parks, and other natural environments, as well as the environment.

We have created a video explaining the use of green infrastructure, which we are working on to adapt to climate change. Please refer to the following link.

In order to eliminate inundation damage caused by urbanization, Yokohama's sewerage business has been working on hardware such as rainwater trunk lines and rainwater regulating ponds and software measures such as hazard maps to support the self support community support.

However, in recent years, as the risk of flooding due to the increase and intensification of natural disasters, which are considered to be the impact of climate change, we are promoting initiatives that utilize green infrastructure as an adaptation measure to minimize and avoid damage in addition to existing measures.

Adaptation measures are to minimize and avoid damage to the effects of climate change.
As one of these measures, it is very effective to utilize the various functions of green infrastructure, such as rainwater recharge and good water circulation, in response to flood damage caused by local torrential rainfalls and other areas.

The park is a green infrastructure with a wide range of functions, including the creation of rest and peace, biodiversity, and heat island measures.
In order to further enhance the park's function as a green infrastructure, we will seize opportunities for new construction and renewal of facilities, improve the water retention and penetration functions by improving the plazas and garden paths to permeable pavement and replacing them with storage penetration crushed stone layers. I am trying to.

Approximately 3,000ha of farmland spreads in the city, and agriculture is actively carried out in places close to citizens.
In green infrastructure initiatives that utilize farmland, we are conducting trial trials to improve water retention and penetration functions and productivity by improving the slope of farmland flat and cultivating the soil in the field deeply.
In this initiative, in cooperation with farmers and universities, we are also verifying the effects of rainwater penetration and growing vegetables.

Yokohama City promotes the installation of rainwater infiltration and rainwater storage tanks in the house to pass on a good water environment to the next generation by recharging groundwater and preserving the waterside and greenery as a green infrastructure that can be used at home. I am. For more information, please refer to the following link.
