Radiation from Chernobyl
What do the Chernobyl disaster, the Three Gorges dam in China and the spread of the Sahel have in common? In each case natural and manmade influences have forced thousands, sometimes millions of people, to leave their land or country of origin.

Barents Sea ecoregion conservation priority areas
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.

Development of organic matter, phosphorus and nitrate in EU 15 rivers
The graphic shows the development of organic matter, phosphorus and nitrate in EU 15 rivers. Water resources in Europe have been profoundly influenced over the past century by human activities, including the construction of dams and canals, large irrigation and drainage systems, changes of land cover in most watersheds, high inputs of chemicals from industry and agriculture into surface and groundwater, and depletion of aquifers. Some of the most...

Biodiveristy in Central Asia
Caspian and Balkhash endemic species are under threat of extinction. It is estimated that ten percent of total area needs to be protected in order to sustain development and the countries of the region are seriously behind that benchmark.

Threat of bad bugs
Locust invasions are a major threat to the agriculture, pasture, food security and social stability of rural populations occupying a very large area from Western Africa to Northern India. Large amounts of chemicals are being used to check this plague, at considerable risk to the environment and public health. As a hazard locusts depend on the wind and rain to travel.

Changes in biodiversity and ecosystems based on human impact 1990-2050
Modelling, using the GLOBIO1 model, over the Arctic, assessing the impacts on the environment based on infrastructure development between 1990 and 2050 in three different scenarios. The development of roads, pipelines and powerlines fragments the natural habitats and reduces the wilderness qualities.

Human impact, year 2032 (sustainability first scenario)
The GLOBIO-2 model is based on settlements and modern infrastructure such as roads, powerlines and pipelines. This map presents the possible situation in 2032, using the GEO-3 security first scenario. This scenario suggests a new environment and development paradigm emerging in response to the challenge of sustainability, supported by new, more equitable values and institutions.

Climate change: processes, characteristics and threats
Most people have heard about climate change, they might even express a real concern about it, but how many would actually consider it a threat? Because the changes can be slow and sometimes difficult to identify within the normal variation of climatic conditions, many of us think they will not affect our lives. However, some parts of the world are already being severely affected by climatic change – both the people and the environment. And unfort...

Deforestation in West Africa: Case Cote-d'Ivoire
The average annual rate of change in total forest area from 1990 to 2000 for the whole of Africa was estimated to be -0.74 %, equivalent to losing more than 5 million ha of forest a year, an area roughly the size of Togo, and the highest rate of any region. (UNEP: GEO [Global Environment Outlook] 3). This graphic shows how deforestation has occurred in Cote d'Ivoire (the Ivory Coast) by comparing the area's forests in 1955 and in 1988. It shows a...

Use of renewables and combustible waste for energy production in 2001; Latin America and the Caribbean
Approximately 12 % of the world’s energy supply comes from renewable energy sources (biomass, waste and other renewables, excluding hydropower).
The average renewable share in Latin America is higher than the world average,. But even if the energy supply from renewables will increase in Latin America, the percentage share of renewables of total energy supply is projected to decrease in the years to come. (World Energy Outlook 2004).

South Eastern Europe to Central Asia: political transition and environmental risks
The graphic maps out the areas that are at risk, or already contaminated from nuclear industry after the break-up of the former Soviet Union. Nuclear power has unresolved problems of waste disposal. Waste remains dangerous for thousands of human generations and can be converted to plutonium, a component of nuclear weapons. The mining of nuclear fuel, containing U-235 and U-238, can pollute groundwater with both heavy metals and traces of radioact...

Biodiversity and protected areas in Macedonia
A map of Macedonia showing all the protected areas, national parks natural reserves. The industry sector is the main polluter in Macedonia. The primary reasons for industrial pollution are the old, inefficient
technologies, inadequate control of waste, and insufficient equipment for environment protection. The most serious problems in the country are the quality of
air in Veles, Bitola, and Skopje; the pollution of surface waters (as a result o...

Ratio of protected areas in the Balkans
The Balkans boast an exceptional wealth of biodiversity of flora and fauna. The main threat to species is increasing anthropogenic pressures such as hunting, farming and the collection of medicinal plants. Natural habitats are threatened by unsustainable economic activities in agriculture, illegal logging of forestry, illegal building and serious pollution. This poses several environmental problems such as erosion, a concern for most of the count...
