What is green infrastructure?

Green infrastructure refers to natural and semi-natural systems that provide various ecosystem services, such as stormwater management, air and water purification, climate regulation, and habitat for wildlife. It includes features such as green roofs, rain gardens, permeable pavement, and urban forests that mimic natural processes to help manage water, reduce pollution, and enhance the overall quality of the environment in urban areas. Green infrastructure is often used as a sustainable and cost-effective alternative to traditional "gray" infrastructure, such as pipes and concrete channels, for managing water and improving the resilience of cities to climate change.

Green infrastructure is a strategically planned network of natural and semi-natural areas that provides multiple benefits to human populations and the environment. These benefits include the provision of ecosystem services such as water filtration, air purification, and climate regulation. Green infrastructure can also help to improve air quality, reduce flooding, and provide recreational opportunities.

Some examples of green infrastructure include:
- Parks
- Green roofs
- Rain gardens
- Urban forests
- Wetlands

Green infrastructure is an important part of sustainable city planning and can help to create healthier, more livable communities.
