Ecosystem services are vital benefits humanity receives from the environment, which are currently diminishing due to factors like deforestation and loss of plant diversity. The global economic value of these services is estimated between $125-145 trillion per year, highlighting their importance for human well-being. Efforts are underway to implement biodiversity strategies and restore damaged ecosystems to counteract the decline in services.

2. Overview
 What are ecosystem services?
 Economic value and current trends of
ecosystem services
 Importance of plants
 Conservation effort and ways forward

3. Ecosystem services
 The suite of benefits that people receive
from the environment (Millenium Ecosystem Assessment, 2005)
 Include:
• Primary production
• Flood control
• Climate regulation
• Waste treatment
• Water purification, etc...

4. Ecosystem services
Provisioning
 Food
 Wood
 Fibre
 Fuel
Regulation
 Climate regulation
 Flood regulation
 Disease regulation
 Water purification
Cultural
 Aesthetic
 Spiritual
 Educational
 Recreational
Supporting
 Nutrient cycling
 Soil formation
 Primary
production
Security
 Personal safety
 Secure resource access
 Security from disasters
Basic material for
good life
 Adequate livelihood
 Sufficient nutrients
 Shelter
Health
 Strength
 Feeling well
 Clean water
Social relations
 Social cohesion
 Mutual respect
 Ability to help others
Freedom of
choice and
action
Opportunity to be
able to achieve
what an individual
values doing and
being

5. Economic value of global
ecosystem services
 Global value estimated between US$125-145
trillion per year.
 Terrestrial ecosystems ~US$75.1 trillion
• Forests ~US$16.2 trillion
• Wetlands ~US$26.4 trillion
• Grasslands ~US$18.4 billion

6. Current state of ecosystem
services
• Capacity of ecosystems to provide services
is decreasing.
• Pressure from deforestation, habitat
modification, fragmentation, intensification
of land use, invasive species, pollution

9. Removal of plant biomass
 Reduced capacity for:
• Flood regulation
• Water purification
• Carbon uptake
• Waste treatment
 Potential for decrease in production of:
• Wood
• Food

10. Reduction in plant diversity
 Over 10,000 threatened plant species.
 Ecosystem productivity decreases with decreased
biodiversity.
 Loss of biodiversity reduces the stability of an
ecosystem.
 Carbon sequestration increases with diversity.

11. Conservation effort to date
 More than 10% of land is now protected in more than half of
the world's ecoregions.
 Many areas of particular importance are protected.
 Reduction in rate of deforestation in tropical forest in many
countries.
 Europe and Asia had an increase in forest cover from 2000-
2010.
 Over 170 countries have biodiversity strategies and action
plans. Global Biodiversity Outlook 3, 2010

14. Ways forward
 Implementation of biodiversity strategies
and action plans.
 First, look after what we still have;
 Second, repair what has been damaged.
 Integration of biodiversity strategies into
broader policies.

15. Summary
 Ecosystem services are the benefits humanity receives
from the environment.
 Capacity of ecosystem services is currently decreasing.
 A loss of plant diversity and biomass plays a role in the
efficiency of ecosystem services.
 Implementation of biodiversity strategies and integration
into broader policies is needed to reverse the current
trend of ecosystem service loss.
