Long-range mercury transport Long-range mercury transport
Coal burning for electric power generation and for industrial purposes continues to increase, especially in Asia (UNEP, 2013). Assessing the global spread and fate of mercury is a challenging task, as there are few studies available about net deposition of different forms of mercury in air, water and land. For example, when mercury moves from air to water and land it is generally in an oxidized gaseous or particle form, whereas when it is remitte...

Emissions to air Emissions to air
Emissions of mercury from ASGM reported for 2010 are more than twice those reported for 2005. While the higher price of gold and increased rural poverty may indeed have caused more activity in this sector, the increased emissions estimates are thought to explained mainly by better data (UNEP, 2013).

Regional mercury emissions in 2010 Regional mercury emissions in 2010
Global emissions of mercury to the air in 2010 from human activities were estimated at 1,960 tonnes. Although it is difficult to compare emissions estimates for individual years, total anthropogenic emissions of mercury to the atmosphere appear to have been relatively stable from 1990 to 2010 (UNEP, 2013). There has been a large shift in regional patterns, however. Economic growth has driven an increase in anthropogenic emissions in Southern and ...

Illustration in a set of graphics prepared for a pilot assessment report on the Black Sea drainage basin, for the UNEP Global Impact on Waters Assessment (GIWA). All data and information were prepared in close collaboration with the GIWA Black Sea team and the GIWA secretariat. The graphics were not used in this form in the final report on the Black Sea, published in 2005.

Selected impacts of climate change in the Caspian Sea region Selected impacts of climate change in the Caspian Sea region
As the concentration of greenhouse gases in the atmosphere increases, the temperature in the European part of the Caspian Sea region will continue to rise, at least at first. Some researchers have recently expressed fears that the warm Gulf Stream current in the Atlantic Ocean may slow down due to the changes in the Artic environment and oceanic circulation.

Human Impact - North America Human Impact - North America
Most areas of North America that have any economic significance - for agriculture, habitation or siliviculture has been converted and modifiedf for human use. Areas with lower degrees of disturbance and fragmentation are found in the vast Arctic areas of Canada and Alaska, as well as in the mountain ranges.

Current and future threats from illegal logging and mining in national parks in Indonesia Current and future threats from illegal logging and mining in national parks in Indonesia
The management and enforcement of the protection regime in Indonesia is insufficient, and illegal activities - such as logging and mining, is rampant. The RAPPAM methodology, developed by WWF, has been used to assess the relative pressures and threats using questionnaires and workshops. Borneo and Sumatra are home to the Orangutan, and the protected areas represent vital habitat for the survival of the species.

Human actions leading to coastal degradation Human actions leading to coastal degradation
Physical alteration and the destruction of habitats are now considered one of the most significant threats to coastal areas. Half of the world’s wetlands, and even more of its mangrove forests, have been lost over the past century to physical alterations, the major causes being accelerating social and economic development and poor-planning (UNEP, 2002). There are currently about one billion people living in coastal urban areas. It is estimated t...
