Definition:
āAn ecosystem is a dynamic functional unit
consisting of all plants and animals (biodiversity)
in an area, together with the nonliving, physical
components of the environment (water, soil and
air) with which they interact.ā
5. www.hampshirebiodiversity.org.uk
Services provided by ecosystems
Provisioning - timber, food, clean air
Regulating - climate, flooding
Cultural - health, recreation and tourism
Supporting - soil formation, water cycling
Social and economic prosperity

Nature and health - benefits
There is compelling evidence that contact with nature
can:
ā¢ alleviate stress and mental health problems
ā¢ improve physical health
ā¢ help recovery from illness
ā¢ improve quality of life for older people
ā¢ enhance social interaction and improve community
cohesion
ā¢ reduce aggression, violence and crime
ā¢ improve childrenās well-being into adulthood

Natureās role in adaptation to climate
change
ā¢ Urban environments (water
retention, shade, cooling, pollution
control)
ā¢ Flood alleviation
ā¢ Renewable energy (woodfuel)

Some statistics
ā¢ The cost of global biodiversity decline under a
business-as-usual scenario is estimated at
Ā£14trillion by 2050 (7% of global GDP)
ā¢ Pollinating insects contribute up to Ā£440m to the UK
economy every year
ā¢ The creation of a network of Marine Conservation
Zones around the UK will provide ecosystem
services worth up to Ā£1.6bn / year
ā¢ The NHS could save over Ā£2bn through increased
access to greenspace

Economics and ecosystems
ā¢ The natural environment has been degraded,
and its services to society compromised,
because it is not easy to put a cash value on
nature. The full value of the natural
environment is not taken into account in cost
benefit analysis.
ā¢ Wider understanding of the services provided
by nature and innovation in economic valuation
and accounting is starting to address this.

Understanding of ecosystem services is
āchallenging the misconception that we
must choose between the natural
environment and economic growthā ā
Natural Environment White Paper
(Consultation, Sept. 2010)

Benefits of the ecosystem services
approach
Understanding the full value of the natural
environment enables:
ļ¼ decisions on the natural environment that do
not compromise benefits to society, business
and the economy
ļ¼ improved delivery of services through better
use of the natural environment
ļ¼ reduced business risk and increased business
opportunity
