Groundwater: aquifers, wells and circulation Groundwater: aquifers, wells and circulation
This graphic illustrates groundwater flow, two types of aquifers (confined and unconfined) and three types of wells (artesian; flowing artesian and a water table well in an unconfined aquifer). It shows how groundwater is circulated through the aquifers and how it is recharged. Groundwater represents one of the most important resources for drinking water for human consumption.

Transboundary Movement of Hazardous Wastes and Other Wastes Among all Reporting Parties in 1997 Transboundary Movement of Hazardous Wastes and Other Wastes Among all Reporting Parties in 1997
This graphic shows the total transboundary movement in 1997 of hazardous wastes and other wastes among all reporting parties to the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal. The graphic shows the total amounts of hazardous wastes and other wastes transferred, in millions of metric tonnes, based on export data, and based on import data. The amounts are shown according to Y categories, which ...

Trends in wind energy generating capacity Trends in wind energy generating capacity
Net annual addition to global wind energy generating capacity, general trend 1980-1995, in megawatts. Wind power represents a possible energy source to replace fossil fuels, like oil and coal, as well as non-renewable energy sources, such as nuclear power.

IPCC and UNFCCC - Institutional framework IPCC and UNFCCC - Institutional framework
In 1988, UNEP and WMO jointly established the Intergovernmental Panel on Climate Change (IPCC) as concern over changes in the climate became a political issue. The purpose of the IPCC was to assess the state of knowledge on the various aspects of climate change including science, environmental and socio-economic impacts and response strategies. The IPCC is recognized as the most authoritative scientific and technical voice on these issues, and it...

Africa: Stockholm convention on persistent organic pollutants (POPs) Africa: Stockholm convention on persistent organic pollutants (POPs)
The process initiated by UNEP in 1995, materialised as the Stockholm convention in May 2001. The convention bans chemicals such as chlordane, DDT and PCB and other organic pesticides and industrial chemicals, as well as establishing precautionary approaches for the future. Most African countries are using agents, such as DDT, for control of disease vectors and pests under exemptions.

Recycling Rates for Organisation for Economic Co-operation and Development (OECD) countries Recycling Rates for Organisation for Economic Co-operation and Development (OECD) countries
Reusing and recycling are natural survival strategies for many people in the developing world. In rich countries we abandoned the habit and are now relearning how to reuse and recycle. Public rubbish collection and a well established recycling industry do a big part of the job for us.

Share of food in total household expenses (Azerbaijan, Kazakhstan, Turkmenistan) Share of food in total household expenses (Azerbaijan, Kazakhstan, Turkmenistan)
In all the areas bordering on the Caspian, priority must be given to diversifying activities and investment. Particular attention should be given to sectors such as tourism, agriculture and food production as well as services.

Mean sea surface temperature on the Caspian Sea Mean sea surface temperature on the Caspian Sea
Recent research by the Caspian Environment Programme estimates the number of living seals to be as low as 150,000. A further reduction in ice cover due to a warming climate could well be one of the major threats facing the Caspian seal in the future.

Comb-jelly (Mnemiopsis leidyi) spreading through the Caspian Sea (invasive species) Comb-jelly (Mnemiopsis leidyi) spreading through the Caspian Sea (invasive species)
The comb jelly (Mnemiopsis leidyi) 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 jelly is an invasive species, brought from North America by ships.

Illegal trade of caviar, 2000-2005 Illegal trade of caviar, 2000-2005
It is not clear to what extent the temporary ban on caviar exports has boosted well established illegal domestic and international trafficking, obviously not accounted for in the official figures. The illegal trade in caviar threatens the sturgeon populations around the Caspian Sea.

Potential environmental hazards in the Caspian Sea Region Potential environmental hazards in the Caspian Sea Region
Oil slicks glittering on the surface of the sea and thousands of hectares of soil penetrated by oil leaking from abandoned wells are just part of the pollution that people living around the Caspian Sea must endure. In addition there are various industries, particularly chemicals and mining, large-scale irrigated farming and untreated household waste. Combined with the effects of the oil, all these forms of pollution have a serious impact on the w...

Total trade in sturgeon caviar, 1999-2003 Total trade in sturgeon caviar, 1999-2003
The caviar trade reportedly fell by about 70% between 1999 and 2003 but there is still every reason to monitor development of the sturgeon population and keep it on the list of endangered species. However it is not clear to what extent the temporary ban on caviar exports has boosted well established illegal domestic and international trafficking, obviously not accounted for in the official figures.

Current and past radiative forcing, from human and natural causes Current and past radiative forcing, from human and natural causes
The radiative forcing from the increase in anthropogenic greenhouse gases since the pre-industrial era is positive (warming) with a small uncertainty range; that from the direct effects of aerosols is negative (cooling) and smaller; whereas the negative forcing from the indirect effects of aerosols (on clouds and the hydrologic cycle) might be large but is not well quantified. Key anthropogenic and natural factors causing a change in radiative fo...

Africa is home to some of the greatest wilderness areas in the world, as well as some of the greatest biodiversity hotspots. The GLOBIO analysis shows that the great deserts and the Central African rain forests have huge remaining tracts that show low human impact and development.
