Water resources in Europe Water resources in Europe
On the continental scale, Europe appears to have abundant water resources. However, these resources are unevenly distributed, both between and within countries. Once population density is taken into account, the disequity in the distribution of water resources per inhabitant is striking.

Trends in groundwater nitrate concentrations Trends in groundwater nitrate concentrations
The graph shows the development of Nitrate concentration in groundwater from 1980 to 1995 in France, Britain and Denmark combined. Nitrate is a naturally occurring compound and is normal in small amounts, but excess amounts can pollute supplies of groundwater. Nitrate travels through soil contaminated by fertilizers, livestock waste and septic systems, carried by rain or irrigation water into groundwater supplies.

Mercury pollution - transport and cycle Mercury pollution - transport and cycle
Mines use toxic chemicals including cyanide, mercury, and sulphuric acid, to separate metal from ore. The chemicals used in the processing are generally recycled, however residues may remain in the tailings, which in developing countries are often dumped directly into lakes or rivers with devastating consequences. The accidental spillage of processing chemicals can also have a serious impact on the environment. For example, at the Baia Mare mine ...

Access to safe drinking water Access to safe drinking water
There are currently more than 1000 million people in the world that lacks access to an easily accessible and safe water source, such as a connection to water mains or a protected well. Instead, water access is limited or available through unprotected sources. The target, under the Millennium Development Goals, is to halve, by 2015, the proportion of people without sustainable access to safe drinking water and sanitation.

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.

Central Asia in peril Central Asia in peril
Communities face appalling health problems. In Karakalpakstan, Uzbekistan, drinking water is saline and polluted, with a high content of metals that causes a range of diseases. Over the past 15 years there has been a thirty-fold increase in chronic bronchitis and in kidney and liver diseases, especially cancer and arthritic diseases have increased sixty-fold. The infant mortality rate is one of the world's highest.

Proportion of population with improved drinking water supply in 2002 Proportion of population with improved drinking water supply in 2002
Access to improved drinking water is estimated by the percentage of the population using the following drinking water sources: household connection, public standpipe, borehole, protected dug well, protected spring, or rainwater collection.

Climate change impacts that could affect attainment of the Millennium Development Goals Climate change impacts that could affect attainment of the Millennium Development Goals
Sustainability in the Latin American and Caribbean countries may be affected by climate change impacts. Costs associated with climate change can intensify budget constraints as countries attempt to reduce poverty and work towards meeting the Millennium Development Goals. Food security will be affected because of a decline in the productivity of staple grains, natural disasters and drought may reduce the time available for children’s education. It...

Inequity in access to clean water and sanitation Inequity in access to clean water and sanitation
The supply of safe drinking water and the provision of sanitation are management issues that raise concerns about inequitable service provision, particularly in developing countries. Although several successful initiatives have been launched to supply safe drinking water to urban populations, efforts still fall short of the required targets for sustainable development. In developing countries water delivery systems are plagued by leakages, illega...

The disappearance of the Aral Sea The disappearance of the Aral Sea
The demise of the Aral Sea in central Asia was caused primarily by the diversion of the inflowing Amu Dar’ya and Syr Dar’ya rivers to provide irrigation water for local croplands. These diversions dramatically reduced the river inflows, causing the Aral Sea to shrink by more than 50%, to lose two-thirds of its volume, and to greatly increase its salinity. At the current rate of decline, the Aral Sea has the potential to disappear completely by 20...

The Mekong River - survival for millions Following the course of the Mekong River helps to understand the human/river hydrological interdependence. From its source on the Tibetan Plateau it drops 5,000 metres and flows across six countries before reaching its delta. More than a third of the population of Cambodia, Lao PDR, Thailand and Vietnam - some 60 million people - live in the Lower Mekong Basin, using the river for drinking water, food, ir...

Freshwater resources: volume by continent Freshwater resources: volume by continent
Glaciers and ice caps cover about 10% of the world’s landmass. These are concentrated in Greenland and Antarctica and contain 70% of the world’s freshwater. Unfortunately, most of these resources are located far from human habitation and are not readily accessible for human use. According to the United States Geological Survey (USGS), 96% of the world’s frozen freshwater is at the South and North Poles, with the remaining 4% spread over 550,000 k...

When the city harms its own water resources When the city harms its own water resources
In areas where surface water is not readily available (located far from areas of need), groundwater is the primary water source. Groundwater aquifers supply an estimated 20% of the global population living in arid and semi-arid regions. Despite their widespread presence, groundwater aquifers in arid areas receive only limited or seasonal recharge, making such aquifers susceptible to rapid depletion. The Northern Sahara Basin Aquifer, for example,...

Total population: access to an improved water source Total population: access to an improved water source
The 2004 global image sadly shows that the lack of access to clean water remains a burden for the poorest countries, preventing them accelerating their development. Essentially handicapping most sub-Saharan African countries, the map shows some curious trends, such as Romania, which remains far behind all other European countries.
