According to the “Wise Use of Mires and Peatlands” by Donal Clarke and Hans Joosten (2002), the following functions of mires and peatlands can be identified:
Instrumental values
Instrumental values are means to an end, i.e. are the beneficial effect of one entity on another entity.
Instrumental values are commonly subdivided into material and non-material life support functions with various subdivisions.
Material life-support values
Material life-support function include regulation, carrier and production function.
Regulation functions:
- regulation of global climate
- regulation of regional and local climates
- regulation of catchment hydrology
- regulation of catchment hydrochemistry
- regulation of soil conditions
Carrier functions – providing space for:
- water reservoirs for hydro-electricity, irrigation, drinking and cooling water, and recreation
- fish ponds
- urban, industrial, and infrastructure development
- waste deposits / landfill
- military exercises and defence
- prisons
- transport and herding
Production functions:
- Peat extracted and used ex situ as/for:
- humus and organic fertiliser in agriculture
- substrate in horticulture
- energy generation
- raw material for chemistry
- bedding material
- filter and absorbent material
- peat textiles
- building and insulation material
- balneology, therapy, medicine, and body care
- flavour enhancer
- Provision of drinking water
- Wild plants growing on mires and peatlands as/for:
- food
- raw material for industrial products
- medicine
- Wild animals for food, fur and medicine
- peat substrate in situ for
- agriculture and horticulture
- forestry
Non-material life-support values
Non-material life-support values include informational and transformation & option functions:
Informational functions:
- social-amenity and history functions
- recreation and aestetic functions
- symbolisation, spirituality and existence functions
- signalisation and cognition functions
Transformation and option functions:
- possibility of modifying preferences, e.g. development of new tastes, improvement of social skills, growing awareness
- creating reassurance that their biological and regulation functions will be there for future generations
Intrinsic values:
Furthermore, peatlands haveĀ intrinsic moral values, the value an entity has in itself, irrespective of its importance to others.
