Title: Global Biodiversity Outlook 3


1
  • The information behind GBO-3
  • 110 National Reports
  • Biodiversity Indicators Partnership
  • Biodiversity Futures Study
  • 500 scientific papers
  • Open review process

2
GBO-3 is an output of the processes under the
Convention. Parties to the Convention, other
Governments, and observer organizations have
shaped the Outlook GBO-3 has been prepared by
the Secretariat of the Convention on Biological
Diversity, in close collaboration UNEP-WCMC. The
production of GBO-3 was enabled by financial
contributions from Canada, the European Union,
Germany, Japan, Spain and the United Kingdom, as
well as UNEP.

Structure
  • Biodiversity in 2010
  • Biodiversity Futures for the 21st Century
  • Towards a Strategy for Reducing Biodiversity
    Loss

4
2010 Biodiversity Target
to achieve by 2010 a significant reduction of
the current rate of biodiversity loss at the
global, regional and national level as a
contribution to poverty alleviation and to the
benefit of all life on Earth
5
The 2010 Biodiversity Target has not been met
  • No sub-target completely achieved
  • Most indicators negative
  • No government claims success
  • Direct pressures constant or increasing

6
  • The global Living Planet Index (LPI), has
    declined by more than 30 since 1970,
  • The Tropical LPI has declined by almost 60.
  • The Temperate LPI showed an increase of 15,
    reflecting the recovery of some species
    populations in temperate regions

  • The Red List Index (RLI) for all these species
    groups is decreasing.
  • Coral species are moving most rapidly towards
    greater extinction risk
  • Amphibians are, on average, the group most
    threatened.

Trends in habitats are varied but show declines
over all
  • Wetlands, salt marshes, coral reefs, seagrass
    beds and sea ice continue to decline
  • Extensive fragmentation of forests and rivers
  • Mangrove decline slowing (except in Asia)
  • The condition of many terrestrial habitats is
    deteriorating (degrading)

Trends shown by agreed indicators of progress

15
Key Findings
  • Projections show continuing and accelerating
    extinctions, habitat loss, changes in
    distribution and abundance of biodiversity
  • High risk of dramatic biodiversity loss and
    degradation of services from tipping points
  • Loss preventable and even reversible with strong,
    urgent action

16
What is a tipping point?
Threshold
Time lag
Self-perpetuating
Long lasting/hard to reverse
17
Tipping Point Amazon dieback
Alternative Path
Current Path
  • Widespread shift from forest to savanna resulting
    from the Interaction of deforestation, climate
    change and fires
  • Becomes more likely at 20-30 deforestation
  • Self-perpetuating
  • Regional rainfall and global climate impacts,
    massive biodiversity loss
  • Keep deforestation below 20-30 of original
    forest area
  • Minimize use of fire for clearing
  • Keep global climate warming below 2-3 degrees

18
Tipping Points Freshwater eutrophication
Current Path
Alternative Path
  • Reduce nutrient inputs from sewage, detergents
    and agriculture
  • Reforestation of watersheds
  • Restoration of wetlands
  • Economic incentives to close nutrient cycle on
    farms
  • The buildup of nutrients from fertilizers and
    sewage shifts freshwater bodies into a eutrophic
    state causing
  • Low oxygen levels and widespread kills of plants,
    fish, invertebrates
  • Loss of nutrition from fisheries, toxic blooms
    make water unfit for drinking or recreation

19
Tipping Points Coral reef collapse
Current Path
Alternative Path
  • Bleaching severe with temperature rise great than
    ca. 2oC
  • Ocean acidification prevents corals forming
    skeletons
  • Reefs become degraded and algae-dominated
  • Livelihood threat to hundreds of millions through
    loss of fisheries and tourism
  • Reduce local stressors including
  • Destructive fishing practices
  • Coastal pollution
  • Over-exploitation of herbivores such as sea
    urchins and fish
  • Strict climate mitigation to keep CO2 levels
    below 450 ppm and 2oC.

Broadening action on biodiversity
21
There is a greater range of options than
previously recognized

22
Scenarios for land use
Business as usual
Carbon tax including land use
Carbon tax on fossil fuels and industry only
Source Wise etal 2009
23
Address climate change and biodiversity loss in
close co-ordination, and with equal priority, if
the most severe impacts of each are to be avoided.
24
Key strategy elements
  • Greater efficiency in use of land, energy and
    fresh water to meet growing demand
  • Use of market incentives and avoidance of
    perverse subsidies
  • Strategic planning
  • Restoration of ecosystems
  • Equitable sharing of benefits from use of and
    access to genetic resources and associated
    traditional knowledge
  • Support and facilitate local action
  • Communication, education and awareness-raising

25
The action taken over the next decade or two will
determine whether the relatively stable
environmental conditions on which human
civilization has depended for the past 10,000
years will continue beyond this century. If we
fail to use this opportunity, many ecosystems on
the planet will move into new, unprecedented
states in which the capacity to provide for the
needs of present and future generations is highly
uncertain.
