Forest Forest ecosystem ecosystem services services
- Forests provide services to people and
societies such as
– maintenance of good air quality and climate – protection of hydrological functions, soils and biological diversity – provision of timber, non-timber forests products and genetic resources – other social, cultural, spiritual, aesthetic, recreational and educational benefits.
- Forest ecosystems do not yield goods
and services of the same quality or quantity at all locations.

A major A major paradigm paradigm change change
- Payments for environmental
services (PES) is a mechanism whereby those who benefit may financially compensate those who provide the services.
- With these payments, the focus
shifts from the control of forest management activities, to the value of environmental services to people.
- PES systems are concrete instruments that incorporate
the value of services into forest management for enhancing sustainable forestry.

PES PES – – an approach based on an approach based on market mechanisms market mechanisms
- This approach incorporates the
economic value of environmental services into the financial decision making process of producers and consumers.
- It relies on the creation of markets for
environmental services, in which providers and beneficiaries of those services interact in pursuit of their respective interests.

Payments provide incentives Payments provide incentives for sustainable management for sustainable management
- Payments aim at influencing the
decisions of the landowners towards practices that maintain or enhance the flow of environmental services, and away from unsustainable activities that diminish the flow of these services.
- Shortcomings in direct regulation approaches to forest
management, and declining government budgets for forest management activities emphasize the need for market-based instruments like PES schemes.
- If markets are to produce welfare improvements, they
need to be designed to provide the correct incentives.

Forests Forests
- protecting
protecting biodiversity biodiversity
- The recreational values related to
forests are large. - In Denmark for example corresponding to more than 150 Euro/hectare and year
- At the same time the world’s forests
provide habitats to about two-thirds
- f all species on earth
- Research tells us that the value that
the preservation of biodiversity has may outweigh the recreational values
- In preservation and restoration
projects, this value may exceed the recreational value by a factor 2 or even much more

The bog is desiccated because of
- water abstraction in the surroundings
- change of tree species from beech to spruce
- ditching of the forest.
Conclusions Conclusions
Forests are very important for recreation and rural development Forests are very important for biodiversity Forests sequester lots of carbon Water from forests is generally of good quality Forests are relatively thirsty and may reduce water in nature and for human use Trees do not grow into the heavens Forest management significantly influences the services And conflicts between the services and between different interest groups are unavoidable But optimization is possible
– if you know how
Overall conclusions/statements Overall conclusions/statements
Never before have so many people demanded so many different and often conflicting goods and services from the forests This calls for improved:
- forest policies,
- forest management, and
- forest research
And it calls for a better co-operation between forest politicians, managers and researchers We are on our way:
- On the Global level: UNFF, FAO, IUFRO, etc.
- On the European level: EU Forest Action Plan, Forest
