Humankind benefits in a multitude of ways from all kinds of ecosystems: agroecosystemss, forest ecosystems, grassland ecosystems, aquatic ecosystems, natural ecosystems, urban ecosystems, etc. Collectively, these benefits are becoming known as ecosystem services. Ecosystem services are regularly involved in the provisioning of clean drinking water and the decomposition of wastes. While scientists and environmentalists have discussed ecosystem services implicitly for decades, the Millennium Ecosystem Assessment (MA) in the early 2000s popularized the concept.[1] There, ecosystem services are grouped into four broad categories: provisioning, such as the production of food and water; regulating, such as the control of climate and disease; supporting, such as nutrient cycles and crop pollination; and cultural, such as spiritual and recreational benefits. To help inform decision-makers, many ecosystem services are being assigned economic values.
This is a classic (largely non-technical) guide: https://escholarship.org/uc/item/2mw607q7
Also check out various pubs from economist Richard Carson: https://scholar.google.com/citations?user=xNFx7VIAAAAJ&hl=en&oi=sra
