2BIODIVERSITY AND IUCN
- IUCN believes that conserving biodiversity
involves addressing (i) species and their
sub-populations (ii) genetic diversity
and (iii) ecosystems. Hundreds of projects are
underway around the world aimed at saving species
and ecosystems and providing the knowledge needed
for successful conservation action. IUCN's
biodiversity conservation work is carried out by
its various programmes including Water, Forests,
Marine, Species, Ecosystem Management and
Protected Areas. The following IUCNs global
programme cater for biodiversity concernsIUCN

3CLIMATE CHANGE AND IUCN
- IUCN believes that conserving nature can help
reduce greenhouse gas emissions (mitigation) and
help us adapt to the impacts of climate change - IUCNs work puts nature at the centre of climate
change solutions in hundred of programmes and
projects across the world - IUCNs Climate Change Network coordinates and
facilitates climate change work across the
Unions programmes, commissions and member
organizations. IUCNs UN Observer Status offers a
unique position at key international
decision-making fora, including the United
Nations Framework Convention on Climate Change
(UNFCCC) - http//www.iucn.org/what/tpas/climate/
4IUCN AND CLIMATE CHANGE ADAPTATION
- The Climate Change Adaptation (CCA) Thematic
Group of IUCNs Commission on Ecosystem
Management (CEM), promotes the science and
practice of Ecosystem-based Adaptation. - Ecosystem-based adaptation (EbA) is the use of
biodiversity and ecosystem services as part of an
overall adaptation strategy to help people to
adapt to the adverse effects of climate change. - EbA aims to maintain and increase the resilience
and reduce the vulnerability of ecosystems and
people in the face of the adverse effects of
climate change.
5IUCN- PEOPLE AND LIVELIHOODS
- IUCN introduced Community-based Risk Screening
Tool - Adaptation and Livelihoods - (CRISTAL)
- CRISTAL can reduce impacts of climate change on
community livelihoods - First tested in IUCN project in Mali
- (Inner Delta of the Niger River)
- Made available by IUCN for wider global use
- (Aliou.Faye_at_iucn.org)
6IUCNS GUIDELINES FOR PRECAUTIONARY PRINCIPLES
- IUCN developed Guidelines for Applying the
Precautionary Principle to Biodiversity
Conservation and Natural Resource Management - Responding to uncertainty (also relevant to
climate change) - www.pprinciple.net
7CC AS DRIVER OF BIODIVERSITY LOSS
- A comprehensive assessment of the links between
ecosystem health and human well-being, climate
change is likely to become the dominant direct
driver of biodiversity loss by the end of the
century - (Millennium Ecosystem Assessment, 2007)
- Projected changes in climate, combined with land
use change and the spread of exotic or alien
species, are likely to limit the capability of
some species to migrate and therefore will
accelerate species loss - (CBD, 2009)
- The impacts of climate change on biodiversity
are of major concern to the UN Convention on
Biological Diversity (CBD). The Convention also
recognizes that there are significant
opportunities for mitigating climate change and
adapting to it, while enhancing the conservation
of biodiversity - Source Millennium Ecosystem Assessment
(2001) - .
8BIODIVERSITY AND CC NEXUS
- The links between biodiversity and climate
change run both ways biodiversity is threatened
by climate change, but proper management of
biodiversity can reduce the impacts of climate
change - Biodiversity and Ecosystem (including forests,
wetlands and oceans) play a role in climate
regulation and impacts regional and global
climate changes) - The changing climate has become a major driver
of biodiversity loss and threatens its role as a
source of essential goods and services
9BIODIVERSITY AND CC NEXUS
- adaptation for biodiversity Adaptation
measures are - needed to protect biodiversity, to enable the
widest range of biodiversity to survive and
adapt, and to meet legal duties for biodiversity
protection. - biodiversity for adaptation Biodiversity can
also play - an integral part in adaptation measures for
other sectors, such as coastal protection by salt
marshes. -

EXAMPLES
IMPACTS
12CC THREATS TO BIODIVERSITY
- Impacts on production of ecosystems
- Shrinking habitats (forests and wetlands)
- Desertification
- Damage to aquatic ecosystems (coral reefs,
fisheries) - Shifts in the natural world (climate change
impacts at least 420 physical and biological
processes), - - Upward migration of plant and animal species,
- - Disappearance of some plant and animal species
in certain areas, - - Impact on breeding behavior,
- - Change in growing season of plants and
agriculture crops, - - Species extinction (some 25 of mammals and
12 of birds are threatened).
13GLOBAL EXAMPLES
Frogs rely on water to breed, any reduction or
change in rainfall could reduce frog
reproduction. Moreover, rising temperatures are
closely linked to outbreaks of a fungal disease
that contributes to the decline of amphibian
populations The projected rise in sea
levels could cause the disappearance of the
tigers habitat, threatening the survival of the
species in coastal forests of Asia
14GLOBAL EXAMPLES
- In Africa, pressures from longer dry periods and
shrinking living spaces are making elephants
highly vulnerable to climate change -
- Australias Great Barrier Reef could lose up to
95 of its living coral by 2050 due to changes in
ocean temperature and chemistry
15CLIMATE CHANGE FACTS- PAKISTAN
- 1. 12th most vulnerable country (Maplecroft 2010)
- 2. Losing at least 19 of GDP each year (Yale
University 2005) - 3. Emission share 0.8 of worlds total- 135th
ranking (in 2008) -
- Total emissions 309 million tones CO2 eqv.
- - comprising of 54 CO2,
- - 36 Methane,
- - 9 Nitrous Oxide
- - 1 other gases
-
- The biggest contributor is the energy sector
with 50 share, followed by the agriculture
sector (39 share), industrial processes (6
share) and other activities (5 share).

20CC AND BIODIVERSITY IN PAKISTAN
- IMPACTS ON FOREST RESOURCES
- Forest lands in northern mountain areas of
Pakistan would shift from one biome to another
(north-ward) which would decrease in the
productivity of this precious resource - Change in specie distribution has been recorded,
some plant species have gained elevation - Lower productivity from forest ecosystems is
predicted due to change in temperature and water
regimes - Spread of pathogens and diseases become frequent
and wider - Incidences of fire (sub-tropical) have become
common due to drought - Mangrove depletetion due to sea intrusion
21CC AND BIODIVERSITY IN PAKISTAN (contd)
- IMPACTS ON FAUNA
- Shrinkage of habitat is intense
- Some species of freshwater mollusks and
amphibians have been found threatened - Higher elevation gained by insects (moths and
butterflies) - Habitat of brown bear has warmed up, distribution
has changed - Long-tailed Marmots are recorded to appear early
from hibernation - Drastic decline in population of migratory birds,
due to depletetion of water bodies and feeding
habitat - Many more we dont know..!!
22CC- AS AN OPPORTUNITY
- Population of large mammals (Markhor and Ibex)
have reportedly been increased due to expansion
of feeding grounds. Since they have gained
elevation and hence are protected from human
influence (conservation value of Markhor US
80000) - Some project interventions have successfully
introduced fish breeding (cold water) and hence
helped in conservation of local fish population
in natural water bodies - Agriculture practices (particularly wheat
cultivation) in northern areas is reportedly
increasing due to higher temperatures. This is
transforming agriculture thus promoting
livelihoods - Increased water flows (glacial melt) is
encouraging for hydro-power generation. IN some
areas, community based micro hydel system has
been adopted
23Transforming agriculture in High altitude areas
