Population using improved water sources in Tanzania Population using improved water sources in Tanzania
The proportion of people in urban areas who use drinking water from improved sources has increased to 83 per cent in 2008, from 68 per cent in 1990 (Government of Tanzania 2008). While more than 80 per cent of people living in urban areas in Tanzania have access to clean drinking water, the figure drops to just over one-third in the rural areas, thus bringing down the national average to about half of the population with access to safe drinking ...

Population using improved water sources in Namibia Population using improved water sources in Namibia
Access by urban households to safe drinking water is slightly less than 100 per cent, but decreasing. Access of rural households to safe drinking water was 88 per cent in 2008, up from 67 per cent in 2000. The government has improved water supply to rural communities through the provision of new boreholes and the rehabilitation of existing boreholes, as well as the development of pipelines. Namibia recycles water, especially in urban areas. This...

Access to clean water and improved sanitation in Mozambique Access to clean water and improved sanitation in Mozambique
The proportion of the population with access to safe drinking water has increased significantly to 56 per cent in 2009, from 37.3 per cent in 1997. The national target for 2015 is 70 per cent. The proportion of the population with access to improved sanitation has increased from 40 per cent in 2003 to 45 per cent in 2009, with a target of 50 per cent for 2015. Thus, Mozambique is likely to meet the 2015 targets for access to water and sanitation...

Households with sustainable access to improved water source in Malawi Households with sustainable access to improved water source in Malawi
According to the Malawi Development Goals Report 2009, the country has already surpassed the MDGs targets for access to clean water and improved sanitation, and is well on its way to achieving 100 per cent for the latter.

Access to safe drinking water in Angola Access to safe drinking water in Angola
Large numbers of people were displaced during the war and moved to urban areas, living in overcrowded slums, where the infrastructure did not exist or could not cope with their influx. The sharp increase in access to safe drinking water by 2004 reflects the emergency assistance and humanitarian resources that flowed in following the peace agreement, but in some cases was not sustainable. Angola has witnessed improved access to sanitation in ...

Renewable water resources in Europe Renewable water resources in Europe
Water resources are a major political issure with most European countries a large portion of their fresh water supply orginating from other countries. Hungary has over 90 percent of its fresh water coming from river flows of other coutries.

Freshwater stress Freshwater stress
Today, the great pressure on water resources is rising human populations, particularly growing concentrations in urban areas. This diagram shows the impact of expected population growth on water usage by 2025, based on the UN mid-range population projection. It uses the current rate of water use per person without taking into account possible increases in water use due to economic growth or improvements in water use efficiency. The regions most v...

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 ...

Freshwater stress and scarcity in africa by 2025 Freshwater stress and scarcity in africa by 2025
According to Population Action International, based upon the UN medium population projections of 1998, more than 2.8 billion people in 48 countries will face water stress or water scarcity conditions by 2025. An area is experiencing water stress when annual water supplies drop below 1700 m3 per person. Water scarcity means that the annual water supply is below 1000 m3 per person. This graphic shows which African nations are expected to be experie...

Renewable freshwater supplies, per river basin Renewable freshwater supplies, per river basin
Freshwater represents a crucial sort for human development, for nature and for ecosystem services. This graphic compares freshwater supplies in cubic metres per capita, per river basin in 1995 with a projection of freshwater supplies for the same areas in 2025. The graphic shows which areas were experiencing water stress, which were experiencing water scarcity and which had sufficient quantities of freshwater in 1995, and shows projections for th...

Urban water supply and wastewater on a shallow aquifer Urban water supply and wastewater on a shallow aquifer
This graphic shows the changes in water supply and wastewater disposal that occur through four stages of growth of a settlement: early settlement; the town becomes a city; the city expands and the city expands further. The changes include increased groundwater pollution and changes in pluvial drainage, the water table and wellfields.

Water towers of Asia - glaciers, water and population in the greater Himalayas-Hindu Kush-Tien Shan-Tibet region Water towers of Asia - glaciers, water and population in the greater Himalayas-Hindu Kush-Tien Shan-Tibet region
The Himalayas–Hindu Kush, Kunlun Shan, Pamir and Tien Shan mountain ranges function as water towers, providing water to people through much of Asia. The glacier-fed rivers originating from the Himalaya mountain ranges surrounding the Tibetan Plateau comprise the largest river run-off from any single location in the world. While the mountains are homes to some 170 million people, the rivers that drain these mountains influence the lives of about 4...

Women quantify lack of control over work resources Women quantify lack of control over work resources
Poor rural infrastructure such as the lack of clean water supply, electricity or fuel increases women’s work load and limits their availability for professional training, childcare and income generation. The lack of access to storage facilities and roads contributes to high food costs and low selling prices.

Wastewater, Health and Human well being - Investing in water supply and sanitation Wastewater, Health and Human well being - Investing in water supply and sanitation
Investment to improve basic access to a safe water source and sanitation (WHO scenario A) can have a significant return with the largest impact on health in particular averting diarrhoea cases and time saved (increasing productivity). Urbanized areas provide a large proportion of GDP, therefore the future development of developing countries is dependent on the productivity of growing urban areas.

Marginal abatement cost curve for Central America in 2030 Marginal abatement cost curve for Central America in 2030
Estimates of the marginal costs of emissions reduction for Central America show that decarbonization options should be directed towards energy efficiency in the residential and services sectors, mainly arising from savings due to reduced energy consumption. Similarly, the mitigation strategy should be focused towards reducing deforestation and degradation, with additional benefits for biodiversity and water supply. Sectors like transportation and...
