Bushmeat trade in Tshuapa-Lomami-Lualaba Region Bushmeat trade in Tshuapa-Lomami-Lualaba Region
Hunting inside protected areas to supply bush- meat is extensive in many regions, and much is transported by bicycle to i.e. larger towns like Kindu. The great apes, sometimes smoked, constitute up to several percent of the total bushmeat, but with devastating impacts on the great ape populations with their slow reproductive rates and complex social structure.

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...

Cheleken Peninsula pollution sources Cheleken Peninsula pollution sources
Khazar (formerly Cheleken) is a town of 10 000 people (once 16 000), located on the Cheleken peninsula on the Caspian shore. Iron bromide (FeBr2) production started at the Cheleken plant in 1940, followed by iodine production in 1976. The production capacity of the plant is about 250 tonnes of iodine a year. The natural water (brine) found here contains radioactive elements. During iodine processing, with the coal-absorption method, radio...

Urban development in Baku Urban development in Baku
The Azerbaijan capital Baku is the largest and fastest growing city with a population of over 2 million. The population has doubled in the last decade and may reach approximately 3.3 million by the year 2030 (UNPD 2005).

Ethnolinguistic groups in the Caspian basin Ethnolinguistic groups in the Caspian basin
The Caspian region has plenty to choose from when exploring past and present civilizations and cultures, historical monuments and the beauty of its natural resources. With unspoilt beaches in the east and west, lush mountain forests in the south, and the majestic Volga in the north, coupled with a mosaic of ethnic origins and cultures, it has the potential to attract thousands of visitors. Yet, the travel trade faces major challenges in th...

Sea level rise in Anzali Lagoon, Iran Sea level rise in Anzali Lagoon, Iran
Fluctuating water levels will affect the population of the coastline and can cause substantial economic damage if appropriate measurements are not taken. A rise in sea level of 1.2 metres would flood Anzali, an Iranian city on the low-lying coastal plain in the southwest corner of the Caspian, and turn it into an island, according to forecasts. This would cost the city billions of dollars and cause massive population displacement. The sce...

Human population growth rates, 1990–2000, and per capita Gross Domestic Product (GDP) and biological productivity in 2000 in ecological systems Human population growth rates, 1990–2000, and per capita Gross Domestic Product (GDP) and biological productivity in 2000 in ecological systems
Millennium Assessment systems with the lowest net primary productivity and lowest GDP tended to have the highest population growth rates between 1990 and 2000. Urban, inland water, and marine systems are not included due to the somewhat arbitrary nature of determining net primary productivity of the system (urban) or population growth and GDP (freshwater and marine) for them.

Net national savings in 2001 adjusted for investments in human capital, natural resource depletion, and damage caused by pollution compared with standard net national savings measurements Net national savings in 2001 adjusted for investments in human capital, natural resource depletion, and damage caused by pollution compared with standard net national savings measurements
Positive values for national savings (expressed as a percent of gross national income) reflect a gain in wealth for a nation. Standard measures do not incorporate investments in human capital (in standard national accounting, these expenditures are treated as consumption), depletion of a variety of natural resources, or pollution damages.

Locations reported by various studies as undergoing high rates of land cover change in the past few decades Locations reported by various studies as undergoing high rates of land cover change in the past few decades
In the case of forest cover change, the studies refer to the period 1980–2000 and are based on national statistics, remote sensing, and to a limited degree expert opinion. In the case of land cover change resulting from degradation in drylands (desertification), the period is unspecified but inferred to be within the last half-century, and the major study was entirely based on expert opinion, with associated low certainty.

Contrast between contemporary and pre-disturbance transports of total nitrogen through inland aquatic systems resulting from anthropogenic acceleration of this nutrient cycle Contrast between contemporary and pre-disturbance transports of total nitrogen through inland aquatic systems resulting from anthropogenic acceleration of this nutrient cycle
While the peculiarities of individual pollutants, rivers, and governance define the specific character of water pollution, the general patterns observed for nitrogen are representative of anthropogenic changes to the transport of waterborne constituents. Elevated contemporary loadings to one part of the system (such as croplands) often reverberate to other parts of the system (to coastal zones, for example), exceeding the capacity of natural syst...

Biodiversity in the Caspian Sea Biodiversity in the Caspian Sea
With the opening of the Volga-Don canal in 1952 navigation between the oceans and the Caspian became possible. Contact between the previously secluded Caspian marine ecosystem and the outside world was consequently inevitable. The connection led to the introduction of various alien species (plants and animals not native to the habitat). The most threatening event for the Caspian ecosystem was the arrival of the North American comb jelly (Mnem...

Total sturgeon catch in the Caspian Total sturgeon catch in the Caspian
The Caspian area is the world’s main producer of wild caviar (83% in 2003) and supplies the four largest markets, the European Union, United States, Switzerland and Japan. The construction of several hydroelectric power plants and dams along the Volga river significantly altered the flow of water into the delta and destroyed about 90 per cent of the sturgeon’s spawning grounds, which can be as far as several hundreds of kilometres upstrea...

Historical decline of the Caspian seal (Pusa caspica) Historical decline of the Caspian seal (Pusa caspica)
The Caspian seal (Pusa caspica) population has declined by more than 90 per cent since the start of the 20th century, falling from more than 1 million individuals in 1900 to around 100 000 today (CEP, 2007). However, at present there are only around 7 to 15 thousand breeding females, meaning the population has very low reproductive capacity. The principle cause of the decline was unsustainable levels of hunting for seal oil and fur throug...

Collapse of Tulka in the Caspian Collapse of Tulka in the Caspian
The comb jelly is well adapted to the habitat (salinity, temperature, and food range) and reproduces faster than endemic species. As it eats the same food as them, it has had a drastic effect on their numbers, upsetting the entire food chain. The commercial fishing industry is afraid of losing the kilka/tulka (g. Clupeonella) and other valuable catches, with consequent effects on human livelihoods and food sources for the Caspian seal and...
