Development of fossil fuel resources in the Arctic, 2005 Development of fossil fuel resources in the Arctic, 2005
Barents Sea: The 2004 lifting of an embargo on offshore hydrocarbon exploration in the Norwegian Barents has renewed activity there. Regulation of exploration is animportant political issue. Debate in 2005 focused on environmental protection and establishing areas free of oil development. In Russia five companies were selected as finalists in the joint development of the Shtokman gas field, in the Barents Sea. This field is estimated to hold twic...

Impact of human activities on reindeer habitat - Barents region Impact of human activities on reindeer habitat - Barents region
The impact of infrastructure development on reindeer potentially threatens the cultural traditions of the Barents region indigenous people and their chosen way of life. The probability of impact on wildlife, vegetation and ecosystems is related to distance to different types of infrastructure. The distance zones of impact are lowest in forest and highest in open tundra. The extent of the zones are based upon several hundred field studies from int...

Hydropower potential (theoretical possitibility for electricity generation) Hydropower potential (theoretical possitibility for electricity generation)
Hydropower, generating electricity through turbines, represents a clean and renewable energy source, but not without problems. Dams and reservoirs disrupt the natural flow, and may increase siltation and evaporation, in addition to severe impacts for wildlife, for instance migrating fish. The gross theoretical capability, presented in this map, represents a calculation based on the topography and precipitation in the countries, and is the amount ...

Species extinction rates Species extinction rates
Comparisons with the rate at which species have disappeared from the planet over a long period of Earth’s history indicate that humans have already increased extinctions levels dramatically. Projections suggest that this rate will take another big leap due to changes over the next 50 years. The bars represent the range of estimates in each case.

The economy of legal wildlife trade The economy of legal wildlife trade
The trade in wild species can contribute significantly to rural incomes, and the effect upon local economies can be substantial. The high value of wildlife products and derivatives can also provide positive economic incentives to provide an alternative to other land use options for the local people - to protect wild species and their habitats, and to maintain the resource for sustainable and profitable use in the medium and long term. Consequent...

Forest vs. Agriculture – the case of the Mabira forest reserve, Uganda Forest vs. Agriculture – the case of the Mabira forest reserve, Uganda
The Mabira forest reserve, on the shores of Lake Victoria hosts valuable wildlife, serves as a timber resource, provides ecosystem services for the water balance and the rainforests represents a tourist destination. Following a proposed plan for clearing a third of the reserve for agricultural use, the values of the forest were calculated by local researchers. This economic evaluation of the forest shows that from a short-term perspective, growin...

The bushmeat chain reaction The bushmeat chain reaction
As many of the parks and surrounding forests have lost 50–80% of their wildlife species, typically antelopes, zebras and other ungulates, the poachers are increasingly targeting primates including gorillas, bonobos and chimpanzees. A significant demand comes from bushmeat hunters to supply militias, refugee camps and mining and logging camps, where much of the work- force is forced. Thirty-four million people living in the forests of Central Afri...

Consumption of harvested meat/fish in Inuit Households (Canada) Consumption of harvested meat/fish in Inuit Households (Canada)
The harvest of natural resources is a key feature of traditional lifestyles and economies throughout the Arctic, and a continuing reliance on it as a mainstay of indigenous existence in the north is evident. Environmental change in Arctic regions is a key contributing factor to changing Inuit subsistence patterns. As examples, the Inuit speak of the thinning of the ice which makes hunting more challenging; species they once relied upon are disapp...

Location of datasets in the Arctic Species Trend Index (ASTI) Location of datasets in the Arctic Species Trend Index (ASTI)
Dramatic changes, such as sea ice loss, are projected to occur in Arctic ecosystems over the next century. Understanding how the Arctic’s living resources, including its vertebrate species, are responding to these changes is essential in order to develop effective conservation and adaptation strategies. Arctic species that are adapted to these extreme environments are expected to be displaced, in part, by the encroachment of more southerly specie...
