Intangible values = attitudes and preferences that are not immediately obvious, e.g. Aesthetic value lies in the brain of the beholder, partly hard-wired by evolutionary processes and partly induced by experience and socialisation. It includes sight, sound, smell, taste, touch and intuition. Intangible values: what are they? The archetypal beautiful view Only regarded as aesthetically attractive by vegetable gardeners

What are the social values of urban woodlands? March, 2003: postal survey sent to 1000 residents aged between 15-75 years randomly sampled. Mapped social values of green areas. Qualitative + quantitative approach. Tyrvainen, L., Makinen, K. & Schipperijn, J. (2007, p. 7). Tools for mapping social values of urban woodlands and other green areas. Landscape and Urban Planning, 79, 5-19.

Study site: East Helsinki, Finland, 10 km from city centre. Mainly young forests, former agricultural land and narrow forested belts. Tyrvainen, L., Makinen, K. & Schipperijn, J. (2007, p. 7). Tools for mapping social values of urban woodlands and other green areas. Landscape and Urban Planning, 79, 5-19.

What are the social values of urban woodlands? How much and what kinds of green areas should be provided for residents in urban areas? Do suburban green areas provide high- quality benefits for residents? Where do residents find attractive and meaningful green areas and what are the characteristics of these areas?

Typology of environmental values
18
Economic valuation methods
19
Travel cost method A revealed preference method Uses actual behaviour and travel costs to reveal underlying preferences of individuals Infers willingness to pay for environmental quality from decisions made about where to travel for recreation. Keohane, N.O. & S.M. Olmstead (2007). Markets and the Environment, Island Press, Washington. p. 33-43
20
Hedonic Pricing A revealed preference method. Uses observed market prices to infer value of environmental amenity that is “bundled” with private goods. Often uses housing market data. Infers from market real estate prices willingness to pay for environmental quality. Keohane, N.O. & S.M. Olmstead (2007). Markets and the Environment, Island Press, Washington. p. 33-43
21
Contingent Valuation Contingent valuation is a stated preference method. People are asked in surveys about their willingness to pay for an environmental amenity, e.g. better air quality. Keohane, N.O. & S.M. Olmstead (2007). Markets and the Environment, Island Press, Washington. p. 33-43
