CC-LandStraD: Climate Change - Land Use Strategies Germany; Subproject: Economic valuation of various forestry land use options with regard to their carbon storage under different environmental conditions
Due to expected climate changes, forestry will have to adapt to changing growth conditions, but forestry itself also provides possibilities to impact the greenhouse gas emissions balance positively by carbon sequestration in forests. Changing environmental conditions will impact all ecosystem goods and services provided by forests and consequentially competition for the usage of various forest goods will change.
The primary goal of the forestry subproject is to analyse und assess in monetary terms climate adapted forestry and its effects on the provision and the regional distribution of forest goods and services. Within this subproject these questions will be dealt with from two different perspectives, one forest economic and one environmental economic part. The environmental economic part of the subproject will deal with the effects of carbon mitigation and climate adaptation strategies on the provision of nonmarket ecosystem goods and services (no exclusivity, no rivalry) of forests and their economic valuation.
For the monetary valuation of cultural ecosystem services of forests a random sample of the population will be interviewed nationwide. Therefore, a separate questionnaire will be developed, using stated preferences methods, i.e. choice experiments.
Economic valuation is conducted by means of a choice experiment. In a choice experiment respondents are successively presented several different alternatives with different attributes. They are then asked to choose the one that is most preferred. Using statistical methods trade-offs between single attributes of the alternatives are determined. This is also done with the price attribute, which indicates the economic value of changes of accompanying attributes.
Results of the monetary valuation show that positive willingness to pay values exist for increasing the Share of forest, and negative willingness to pay values (i.e., compensation requests) are found for decreasing the Share of forest.
Changes in forest characteristics leading to an increase in Biodiversity and Age of forests are valued positively. All other changes are valued negatively. This includes reductions in the amount of Understorey in forests and substantial reductions in the amount of Unused forests. Regarding the choice of tree species negative willingness to pay values are found for changes in the amount of Exotic tree species as well as high levels of Coniferous trees.
Measures changing the Field size (in any direction) are valued negatively.
Results depend to some extent on current situations in respondents' surroundings.
