rainwater accumulations in natural underground reservoirs

Colombia
deforestation; soil and water quality damage from overuse
of pesticides; air pollution, especially in Bogota, from vehicle
emissions

Comoros
soil degradation and erosion results from crop cultivation
on slopes without proper terracing; deforestation

Congo, Democratic Republic of the
poaching threatens wildlife
populations; water pollution; deforestation; refugees responsible
for significant deforestation, soil erosion, and wildlife poaching;
mining of minerals (coltan - a mineral used in creating capacitors,
diamonds, and gold) causing environmental damage

Congo, Republic of the
air pollution from vehicle emissions; water
pollution from the dumping of raw sewage; tap water is not potable;
deforestation

Cook Islands
NA

Coral Sea Islands
no permanent fresh water resources

Costa Rica
deforestation and land use change, largely a result of
the clearing of land for cattle ranching and agriculture; soil
erosion; coastal marine pollution; fisheries protection; solid waste
management; air pollution

Cote d'Ivoire
deforestation (most of the country's forests - once
the largest in West Africa - have been heavily logged); water
pollution from sewage and industrial and agricultural effluents

Croatia
air pollution (from metallurgical plants) and resulting acid
rain is damaging the forests; coastal pollution from industrial and
domestic waste; landmine removal and reconstruction of
infrastructure consequent to 1992-95 civil strife

Cuba
air and water pollution; biodiversity loss; deforestation

Cyprus
water resource problems (no natural reservoir catchments,
seasonal disparity in rainfall, sea water intrusion to island's
largest aquifer, increased salination in the north); water pollution
from sewage and industrial wastes; coastal degradation; loss of
wildlife habitats from urbanization

Czech Republic
air and water pollution in areas of northwest Bohemia
and in northern Moravia around Ostrava present health risks; acid
rain damaging forests; efforts to bring industry up to EU code
should improve domestic pollution

Denmark
air pollution, principally from vehicle and power plant
emissions; nitrogen and phosphorus pollution of the North Sea;
drinking and surface water becoming polluted from animal wastes and
pesticides
