Arktis – några utmärkande drag Mycket och relativt
ostörd natur Relativt få invånare –
urspurngsbefolkning delar regionen med nybyggare
Alla landområden regleras genom de arktiska ländernas nationella lagar
Arktis resurser tilldrar sig stort intresse från många delar av världen
Olja, gas och mineraler blir mer och mer intressant
Globala föroreningar och klimatförändring har redan påverkat Arktis
Is enough being done??? Yes... no... maybe...... Yes, because wildlife is abundant and there are
very many protected areas throughout the Arctic, No, because traditional conservation approaches
do not tackle today’s environmental problems, such as POPs and other pollutants, climate change etc.
Maybe, because there is still room for much improvement
Biodiversity in the Arctic High Arctic and desert
ecosystems have much in common. Species are true fighters for survival. Many species demonstrate relatively high resilience against disturbances.
Fjällglim (Silene acaulis)
Silvertärna (Sterna Paradisaea)
Adventdalen, Svalbard
The Arctic is characterized by a harsh climate with extreme variation in light and temperature, short summers, extensive snow and ice cover in winter and large areas of permafrost. The plants and animals of the Arctic have adapted to these conditions, but these adaptations have in some cases rendered them more sensitive to human activities. Human activities both inside and outside the Arctic influence the physical, chemical and biological nature of Arctic ecosystems.

Växternas ekologiska anpassningar Fjällvallmons blomma bildar en kapsel som koncentrerar solens strålar till blommans mitt, där fröna bildas.
Blommorna följer solens gång över himlen för att ytterligare skynda på fröbildningen.
Fjällvallmo (Papaver radicatum)
Ekologiska opportunister på Svalbard
Eftersom det nästan inte finns några smågnagare på Svalbard kan inte rovfåglar överleva. Den stora vittruten har därför tagit över rollen som rovfågel och är luftens store härskare på Svalbard.
Avsaknaden av smågnagare på Svalbard har gjort att fjällräven förlitar sig på andra födokällor, som t.ex. sjöfågel eller döda renar. Fjällrävar har även setts “adoptera” isbjörnar, och följer då med ut på havsisen där räven livnär sig på resterna från isbjörnens säljakt. Fjällräv (Alopex Lagopus)
En av världens sista stora vildmarker Jämfört med de flesta andra områden på
jorden, så finns det mesta av naturen i Arktis kvar i sitt naturliga tillstånd
En del miljöproblem föranleder oro, på grund av en kombination av olika förhållanden, för befolkningen i Arktis och för vissa ekosystem
Dessa förhållanden förekommer ibland på en lokal nivå, men kan även vara både regionala eller cirkumpolär i omfattning
Klimatförändring
1990
2003
"Climate change in the Polar Regions is expected to be among the largest and most rapid of any region on the Earth, and will cause major physical, ecological, sociological, and economic impacts, especially in the Arctic".
Detta är den sammanfattande slutsatsen i den senaste rapporten från IPCC (Intergovernmental Panel on Climate Change).
Vikande permafrost ökar växthuseffekten Widespread loss of discontinuous permafrost will trigger erosion of ice-rich landscapes, change hydrologic processes, and release CO2 and methane to the atmosphere. Changes in the cryosphere will reduce slope stability and increase incidence of natural hazards for people, structures, and communication links. Buildings, roads, pipelines, and communication links will be threatened.
The Gulf Currents possible future Two major engines drive the Gulf Current. Winds bring
warm surface water from Africa to the Gulf of Mexico and then across the Atlantic Ocean towards Europé. Cold and salt surface water in the North Atlantic sinks to the bottom, and is replaced by the Gulf Stream’s warm surface water. The result is a favourable climate in Europé.
Diminishing deep water formation could slow down the Gulf current’s flow, which may lead to a colder climate in Northern Europé and northwest Russia.
What will happen if the Gulf Current cease to flow? With average temperatures 2-5 degrees C lower
than today, Northern Europe may experience a climate and natural conditions similar to Churchill in Canada, i.e. tundra and barren land.
Not to mention possible dramatic changes in all life on land and in the seas. And changes may come fast…
Ecological consequences of climate change Climate change may diminish
distribution and abundance of high Arctic species. Alien species may invade (e.g. pests)
Timberline may be pushed further north.
Overfishing may have consequenses for seabirds and land living animals
New transport routes will lead to increased risk of accidents
The Northern Sea Route Massive oil spills along northern Russian waters can be
trapped in the ice and destroy marine ecosystems over wide areas. Ultimately, oil can be carried with ocean currents to areas far away. There are few, if any, techniques that allow for proper handling of such scenarios.
The social, economic and environmental impacts of futre NSR operations and associated gas, oil and mineral exploration, plus subsequent shipwrecks and spills, represent significant concerns and challenges for the future.

Trenden går att vända Bly
Implementation of the 1979 Geneva Convention on Long Range Transboundary Air Pollution (Box 2) and the Stockholm Convention on Persistent Organic Pollutants is important for reducing the burden of contamination on the Arctic and its inhabitants
Polar bears in a changing environment Polar bears were
effectively protected against hunting all over the Arctic in 1973.
But what now, with retreating sea ice, pollution etc ...?
POPs in Svalbard’s polar bears may affect reproduction and survival
Polar bear blood plasma samples collected in Svalbard in 1967 were analyzed for POPs and compared with values from 1993-94.
Differences ranged from a decrease for a limited number of compounds to a ten times increase in others. The increase suggests selective metabolism and accumulation of organochlorines in polar bears.
Biomagnification Biomagnification occurs when contaminant
levels are increased with each step in the food web.
Predators consume the contaminants stored in their food (prey), and in turn include the contaminats in the food of these prey, etc.
Svalbard’s polar bears are also effected by climate change Retreating sea ice prevetns pregnant females to reach the
shores of their traditional denning areas in late autumn. Less ice also means fewer seals to hunt, and increased
difficulties for female bears to cater for her offspring Juvenile bears lack the hunting experience of older bears
and may starve when seals become less abundant Fewer dens means fewer births. Less foos means
increased motalities. The net result: Less recruitment to the population
Exploatering största hotet mot miljön i Arktis
The Arctic is a major supplier of oil, gas and other minerals The Arctic contains huge deposits of oil, gas and
minerals, and may become one of the world’s major gas and oil suppliers in the future.
Vast pipeline projects are under preparation for export to China, Japan, Korea and other Pacific countires.

Challenges Will we be able to maintain Arctic ecosystems
and wildlife under threats from pollution and climate change?
Do we have institutions and legislation that allow us to manage the Arctic’s nature and wildlife sustainably?

Avfallshantering
Avfallshantering Minimize waste
production Remove all waste
from Antarctica Prohibited items
- PCB, pesticides - polystyrene chips/beds - non-sterile soil
Packaging, handling and labelling
Separation and recycling Metal Glass mixed solid sewage, food liquid kitchen
Kemikaliehantering
Fuel management Proper handling during transport, storage and
transfer Use absorbent materials during refuelling
operations as far as possible Stop the flow, contain the spill and initiate clean-
up action if you observe fuel spills or leaks Report spills larger than 200 litres to expedition
leader immediately
Oil spill
Initial assessment - Type 1 < 200 litres - Type 2 > 200 litres - Type, Location, Risk
Health and safety - Ensure safe working conditions
Resources at risk - Ice-free ground - Ice-covered ground - Snow-covered ground
Spill response - Be familiar with OSCP - Spill equipment
General procedure for oil spill Try to stop or minimise any further spillage. Deploy absorbents to contain the oil. If possible, use pumps to remove the fuel from
the ground straight into 200 litre drums. Absorbent pads should be spread on any
remaining oil that cannot be manually removed. Oil soaked absorbents must be picked up and
placed in plastic bags or empty 200 litre drums.
Environmental incidents Report all incidents to Expedition Leader
according to procedures for Emergency response and preparedness
Events or incidents leading to environmental hazard are reported to COMNAP and the ”Environmental Incident Reporting System”
Fuel spills are the most common incidents – spill prevention cautions are the most important
Generella riktlinjer och principer
Code of Conduct Vegetation is scarce and sensitive
- Avoid trampling and harmful interference - Aware of risk of introducing non-native species
Birds and mammals are more stressed than they appear - Keep your distance, be calm and quiet - Do not harmfully interfere - Be aware of risk of introducing diseases
Code of Conduct Waste and Pollutants
- Zero emissions the goal Protected areas
- Do not enter without a permit Site management
- A site should always be left in its natural condition - No “souveniring”
Before you go……….. Get the facts! When packaging, remember to Only bring what you will need Get rid of unnecessary packaging material Use packaging material that can be re-used Do not bring PCB, pesticides, non-sterile soil Avoid products made by PVC
När du packar, tänk på att Ta med så lite packning
som möjligt Minimera förpackningar Använd inte skumplast
av någon form Undvik plastpåsar
TACK FÖR UPPMÄRKSAMHETEN
FRÅGOR?
Old and new approaches to indigenous people’s rights and roles in conservation and sustainable use
Before it was: Now it is: * Preserve * Protect * Prohibit * Participate * Punish * Profit
Infant mortality in selected regions of the Arctic
Challenges ahead - oil in the sea-ice Oil is trapped in open leads and under ice where
production is high and where fish, seals and birds feed.
It takes long time to break down – and is very difficult to clean up in ice covered waters.
Oil can be transported with the drifting ice over very long distances, to seas and shores very far away.
Differences between the Arctic and Antarctica International cooperation in the Arctic is often
hampered by the bordering states domestic and political agendas. Adoption of an Antarctic style treaty is unlikely for the Arctic.
Neverthells, there is room for improvments
The Arctic – a remote hinterland? Challenges, problems and concerns are correlated with
distance in space and time. Europe’s main concernms and and immediate interests lie beyond the Arctic region.
We tend to concentrate upon today’s challenges, and leave concerns about the far-away Arctic to future generations.
Communication with politicians and decision-makers Politicians and decision-makers rarely have time
and capacity to read extensive reports and to absorb their messages.
TV, magazines and newspaper articles are the media. Plus brainstorming and briefings whenever possible.
The Arcitc has very many, large protected areas, but…….. Several of them do not recognise animal’s
homerange and seasonal distributions Some of them allow mineral extraction and
associated infrastructure development Most of them do not allow for harvests of plants
and animlas e.g. for subsistence by traditional users (indigenous people)
Protection of Svalbards barnacle geeese – a success story
In the 1940’s Svalbards population of barnacle geese had beeen reduced to only 300 birds, mainly becausse of hunting in Svalbard and along its migratory routes.
The geese are now protected in winter ranges in the UK. Hunting is prohibited in Svalbard and sanctuaries are established along Spitsbergen’s west coast.
Through effective protection throughout the year, the Svalbard population is now estimated at 23 000 geese.
Pollution in the Arctic Pollution carried from Europé to the Arctic by air
and ocean and river currents, has had a major impact on the Arctic environment.
Industry in and around the Arctic aslo contributes significantly to contamination, with sources including copper-nickel smeltees on the Kola Peninsula and at Norilsk in Siberia.
