Trends in regional average surface temperature in the Ferghana Valley area Trends in regional average surface temperature in the Ferghana Valley area
An important factor when looking at the region in terms of environment and security is the impact of climate change in Central Asia in general, and Ferghana Valley in particular. By modifying people’s livelihood, climate change may have an important security dimension in conjunction with other aggravating factors. In the Ferghana valley it is likely that climate change will primarily affect sector related to water and agriculture. Central Asia is...

Industrial pollution and waste hotspots in the Ferghana Valley Industrial pollution and waste hotspots in the Ferghana Valley
Mercury mining, uranium mining, chemical and textile industries, oil facilities and processing plants which contribute to the contamination of the soil with highly toxic heavy metals are recognized as environmental challenges in the region. Even though past spills and contaminations have caused tensions between the different countries of the region, officials do not consistently regard environmental pollution by existing facilities as a security ...

Arctic map, political Arctic map, political
The Arctic is extremely diverse in terms of landscapes, varying from pack and drift ice to rugged shores, flat coastal plains, rolling hills and mountains surpassing 6000 metres above sea level (Denali, 6,194 m asl, in sub-arctic and boreal Alaska). The region has rivers and lakes, tundra and the largest forests in the world (the Russian Taiga). This is a simple grayscale political map.

Re-infestation by 'Aedes aegypti' Re-infestation by 'Aedes aegypti'
Climate change affect the health of the population, not only through heat waves and waterborne diseases, but also as a result of the expansion of geographical areas conducive to the transmission of vector-borne diseases such as yellow fever, dengue and malaria. Species of mosquitoes, such as the group ‘Anopheles gambiae’, ‘A. funestus’, ‘A. darlingi’, ‘Culex quinquefasciatus’ and ‘Aedes aegypti’, are responsible for propagation of the majority of...

Water, irrigated cropland percentage by region Water, irrigated cropland percentage by region
Irrigated land currently produces 40% of the world’s food on 17% of the world’s land. A broadening of irrigation and more effective rain fed agriculture will be necessary to meet the need for increasing agricultural outputs – for domestic use and exports.

Number of people in the mining sector in selected countries in Sub-Saharan Africa Number of people in the mining sector in selected countries in Sub-Saharan Africa
There is 1.5 million small-scale miners estimated to work within whole SADC region. Main countries for small-scale mining activities are Tanzania miners and Zimbabwe, where more people are involved in the small-scale, rather than in the large- and medium-scale mining industry.

Barents Sea ecoregion conservation priority areas and oil and gas infrastructure Barents Sea ecoregion conservation priority areas and oil and gas infrastructure
The Barents Sea ecoregion - the part of the World Ocean north of the Nordic countries and Northwest Russia, has a unique environment with major sea bird colonies, rich benthic and plankton fauna and many major sea mammal species. To identify priority areas for conservation, thirty experts delineated sea areas based on ecological criteria in a WWF study. One of the main threats to the region is the development associated with the expansion of foss...

Protected areas in the Arctic Protected areas in the Arctic
The Arctic is a unique region in the world, with very little human activity and vast expanses of tundra and taiga that presents ecological values. This graphics presents the areas that currently are protected for conservation, as recognized by the IUCN in the World Protected Areas Database at UNEP-WCMC, 2005. Some areas, like the Dehcho territory in Canada have been placed under interim protection. The data for Russia has been updated from nation...

Trends in spring snow cover duration for the Northern Hemisphere, 1970-2004 Trends in spring snow cover duration for the Northern Hemisphere, 1970-2004
Examination of regional trends in spring snow-cover duration from 1969–2003 using NOAA snow-cover data shows the western United States to be among the regions with the strongest decreases. This supports results from studies based on measurements on the ground. Springtime snow cover shows a decline particularly in the Pacific Northwest region of the western United States, where snow water equivalent, a common snow cover measurement equivalent to t...

Water towers of Asia - glaciers, water and population in the greater Himalayas-Hindu Kush-Tien Shan-Tibet region Water towers of Asia - glaciers, water and population in the greater Himalayas-Hindu Kush-Tien Shan-Tibet region
The Himalayas–Hindu Kush, Kunlun Shan, Pamir and Tien Shan mountain ranges function as water towers, providing water to people through much of Asia. The glacier-fed rivers originating from the Himalaya mountain ranges surrounding the Tibetan Plateau comprise the largest river run-off from any single location in the world. While the mountains are homes to some 170 million people, the rivers that drain these mountains influence the lives of about 4...

Projected winter temperature changes in the Arctic Projected winter temperature changes in the Arctic
The changes in cold-season mean temperatures over Arctic land regions are broken into three latitudinal bands for each region, as shown on the small map (which has an outer rim of 50° N). Error bars represent standard deviation from the mean. Where greater warming is projected at higher latitudes than at lower latitudes, temperature gradients will be reduced along large north-flowing rivers and this will likely reduce break-up severity. The rever...

Major mineral fuel resources in Europe, Caucasus and Central Asia Major mineral fuel resources in Europe, Caucasus and Central Asia
Mineral fuels for electricity and heat generation take primarily two forms: fossil fuels in the form of oil, natural gas and coal, and uranimum ore for nuclear power. Oil and gas are distributed in different belts, primarily in the North Sea, Caucasus and Northern Russia. Coal in different forms is still an important fuel resource and resources are distributed over the region. Uranium resources are primarily in Ukraine and Central Asia.

The Western part of the Eurasian continent, has some of the most populated and fertile parts of the World. Central Europe is densely populated, with few remaining fragments of undisturbed habitat, except for the mountain ranges. In the north - Scandinavia and Northern Russia, there is the taiga belt, with vast expanses of confierous forest, and further north, there is tundra and glaciers. Central Asia and Caucasus is a diverse region, with desert...

Renewable energy production in Europe and Central Asia 2004 (heat production and electricity generation) Renewable energy production in Europe and Central Asia 2004 (heat production and electricity generation)
Hydropower, generation of electricity from dams in rivers, represents the majority of the energy produced, so far, with waste incineration - both from municipal and industrial sources, as a distant second. Other energy sources, such as biomass, windpower and solar power represents a very little share of the renewable energy produced so far. Energy consumption has been increasing in the region, since the 1990s, and with it the emissions of greenho...

The “Hole”: a result of special weather conditions over the pole repeated every spring The “Hole”: a result of special weather conditions over the pole repeated every spring
The Antarctic continent is circled by a strong wind in the stratosphere which flows around Antarctica and isolates air over Antarctica from air in the midlatitudes. The region poleward of this jet stream is called the Antarctic polar vortex. The air inside the Antarctic polar vortex is much colder than midlatitude air.” “When temperatures drop below -78°C, thin clouds form of ice, nitric acid, and sulphuric acid mixtures. Chemical reactions on th...

During a 20 year period between 1981 to 2000 the amount of agricultural research by developing nations has outgrown those of higher income countries. The increase has been steady throughout the entire period as it is in the Asia Pacific region.

Pig farming in the Caucasus ecoregion Pig farming in the Caucasus ecoregion
Over the recent number of years, as the economy came to a standstill, individual farms have replaced collective farming and subsistence agriculture and livestock breeding (cattle, sheep and goat) have became common. Along with the increase in farming, more and more land has been used as pasture land. Despite their low productivity, high Mountain areas are increasingly used as pasture grounds for sheep - leading to soil erosion and evoking avalanc...
