ependence on large-scale desalination facilities

Romania
soil erosion and degradation; water pollution; air pollution
in south from industrial effluents; contamination of Danube delta
wetlands

Russia
air pollution from heavy industry, emissions of coal-fired
electric plants, and transportation in major cities; industrial,
municipal, and agricultural pollution of inland waterways and
seacoasts; deforestation; soil erosion; soil contamination from
improper application of agricultural chemicals; scattered areas of
sometimes intense radioactive contamination; groundwater
contamination from toxic waste; urban solid waste management;
abandoned stocks of obsolete pesticides

Rwanda
deforestation results from uncontrolled cutting of trees for
fuel; overgrazing; soil exhaustion; soil erosion; widespread poaching

Saint Barthelemy
with no natural rivers or streams, fresh water is
in short supply, especially in summer, and provided by
desalinization of sea water, collection of rain water, or imported
via water tanker

Saint Helena
NA

Saint Kitts and Nevis
NA

Saint Lucia
deforestation; soil erosion, particularly in the
northern region

Saint Martin
fresh water supply is dependent on desalinization of
sea water

Saint Pierre and Miquelon
recent test drilling for oil in waters
around Saint Pierre and Miquelon may bring future development that
would impact the environment

Saint Vincent and the Grenadines
pollution of coastal waters and
shorelines from discharges by pleasure yachts and other effluents;
in some areas, pollution is severe enough to make swimming
prohibitive

Samoa
soil erosion, deforestation, invasive species, overfishing

San Marino
NA

Sao Tome and Principe
deforestation; soil erosion and exhaustion

Saudi Arabia
desertification; depletion of underground water
resources; the lack of perennial rivers or permanent water bodies
has prompted the development of extensive seawater desalination
facilities; coastal pollution from oil spills

Senegal
wildlife populations threatened by poaching; deforestation;
overgrazing; soil erosion; desertification; overfishing

Serbia
air pollution around Belgrade and other industrial cities;
water pollution from industrial wastes dumped into the Sava which
flows into the Danube

Seychelles
water supply depends on catchments to collect rainwater

Sierra Leone
