Under the influence of nature: The contribution of natural capital to tourism spend.

Tourism and outdoor leisure is an important economic sector for many countries, and has a substantial reliance on natural capital.

Typically, when valuing tourism and outdoor leisure, all expenditure associated with the activity is assigned to the ecosystem it occurs in.
