Landscape Functions

Traditionally, the concept of landscape functions has been considered in the landscape planning system of Germany and German-speaking countries. According to that concept, landscape has the following functions:

(1) Production (economic) functions (biomass production, water supply, suitability of nonrenewable resources);

(2) Regulatory (ecological) functions (regulation of material and energy fluxes, hydrological and meteorological functions, regulation and regeneration of populations and bio(geo)coenoses, habitat (genetical) function); (3) Social functions (psychological (esthetic and ethical) functions, information functions, human-ecological, and recreational functions).

This approach is very similar to the concept of ecosystem services and natural capital, which has recently gained extensive popularity. According to this concept, the typology of landscape functions includes four categories: (1) provisioning functions; (2) regulation functions; (3) habitat functions; and (4) cultural and amenity functions (see Table 1).

1. Provisioning functions comprise functions that supply 'physical services' in terms of resources or space. This category has been divided into two classes: production and carrier functions. Production functions reflect resources produced by natural ecosystems, for example, the harvesting of fish from the ocean, pharmaceutical products from wild plants and animals, or wood from natural forests. Carrier functions reflect the goods and services that are provided through human manipulation of natural productivity (e.g., fish from aquaculture or timber from plantations). In these cases, the function offered by nature is the provision of a suitable substrate or space for human activities, including agriculture, mining, transportation, etc.

2. Regulation functions result from the capacity of ecosystems and landscapes to influence ('regulate') climate, hydrological and biochemical cycles, Earth surface processes, and a variety of biological processes. These services often have an important spatial (connectivity) aspect; for example, the flood control function of an upper watershed forest is only relevant in the flood zone downstream of the forest.

3. Habitat functions comprise the importance of ecosystems and landscapes in maintaining natural processes and biodiversity, including the refugium and nursery functions. The refugium function reflects the value of landscape units in providing habitats to (threatened) fauna and flora, and the nursery function indicates that some landscape units provide a particularly suitable location for reproduction and thereby have a regulating impact on the maintenance of populations elsewhere.

4. Cultural and amenity functions relate to the benefits people obtain from landscapes through recreation, cognitive development, relaxation, and spiritual reflection. This may involve actual visits to the area, indirectly enjoying the area (e.g., through nature movies), or gaining satisfaction from the knowledge that a landscape contains important biodiversity or cultural monuments. The latter may occur without having the intention of ever visiting the area. These services have also been referred to as 'information functions'.

The evaluation of landscapes for planning and management purposes, as well as landscape synthesis and decision making, is based on landscape functions.
