Introduction
Global change has now affected all ecosystems on Earth through processes of land-use change,
climate change and resource acquisition. Ecosystems are vital for human well-being and
development through the goods and services they provide. The interactions between ecosystem
services, human needs and human effects on ecosystems are a core issue in global change and
require much improved scientific understanding if they are to be managed in ways beneficial to
human societies and ecosystem sustainability. This requires the ability to link expert knowledge
with community understanding and other knowledge systems. The theory of ecosystem services
therefore is closely linked to human endeavours and the social sciences; in fact several authors
define ecosystem services principally by their service component relevant to human societies.
Obstacles to the implementation of such an integrated understanding include:
- Only if ecosystem services can be assigned a value, can their preservation be compared with the
opportunity cost of development, land use change or resource utilisation, which may then serve to
guide policy and legislation. The values of ecosystem services are too complex to simply be
monetarised and other measures must be developed to guide decision making.
- Ecosystem services cannot be commoditised; they are tied to locale, to specific landscapes and
environments and the loss in one region cannot normally be compensated by conservation or
gains in other regions. A focus on carbon balances in public debate has obscured this relationship.
- Often those who benefit from and those who affect ecosystem services are not identical. For
instance provisioning services used by traditional populations, that depend on biodiversity, may
be eliminated by land-use change which generates economic benefits for different social actors. A
lack of a direct consequences from deteriorating ecosystem services to managers of such services
implies that the management needed to sustain services lacks self-regulation. The use of and
dependence on ecosystem services by cities is a particularly difficult - and therefore interesting -
