Green Infrastructure is an interconnected network of green spaces and other environmental assets that conserves the functions of the natural ecosystem and provides associated benefits to people (Benedict and McMahon 2002). In West Michigan, green infrastructure includes, but is not limited to, the following:

What are Ecosystem Services?

Ecosystem Services are the direct and indirect benefits that people obtain from ecological systems (Millennium Ecosystem Assessment 2003). Benefits may vary between different systems and many are essential to human existence: e.g., food, water supply and disease regulation help maintain our physical health, and non-material ecosystem services help maintain our psychological well-being.

What is Economic Valuation?

Economic Valuation is the assignment of direct and indirect costs and benefits from a human point of view (Tietenberg 2006).

Green Infrastructure, Ecosystem Services and Economic Valuation are interconnected. This diagram looks at these linkages for one West Michigan land use.
