Lecture outline

• defines intangible values
• describes some of the ways in which intangible

3
Intangible values what are they?
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.
Only regarded as aesthetically attractive by
vegetable gardeners
The archetypal beautiful view

Temporal and spatial variation in aesthetic
preference related to intergenerational
differentiation, culture and class

How do we integrate environmental values into
decisions

• when they are
• intangible
• often conflicting
• time-consuming to obtain
• difficult to separate out.
• Often left out or insufficiently recognised in
  decisions that alter or exploit space, place and
  nature.

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.

agricultural land and narrow forested
belts. Tyrvainen, L., Makinen, K. Schipperijn,

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.

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.

and the Environment, Island Press, Washington. p.

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.
