Natural resource - water (freshwater run-off) Natural resource - water (freshwater run-off)
Freshwater – a natural resource which has been adopted as a human right by the UN in 2002: 'the human right to water entitles everyone to sufficient; affordable; physically accessible; safe and acceptable water for personal and domestic uses'. People depend on this resource for drinking and cooking, for irrigation of farms, for hygiene and sanitation and for power generation. The map presenting this resource only focuses on one part of the geogra...

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.

Water supply and sanitation coverage in Africa Water supply and sanitation coverage in Africa
The water supply situation in Africa is already precarious, and climate change is expected to exacerbate the problem. This graphic shows the amount of water supply coverage at the national level for Africa, and the amount of sanitation coverage, as a percentage, at the national level for Africa. Statistics are shown for rural areas, for urban areas, and for all areas.

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...

Total population: access to sanitation Total population: access to sanitation
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.

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,...

Access to sanitation in urban Africa Access to sanitation in urban Africa
The number of people in Africa with access to improved sanitation, defined as “one that hygienically separates human excreta from human contact” (WHO/UNICEF 2010), has increased over the last two decades. Still, because of the rapid urbanisation, the proportion of the urban population with access to improved sanitation is on the decrease.

Access to sanitation in Yaoundè Access to sanitation in Yaoundè
Proper disposal of sewage is essential for urban water quality, and in Yaoundè the treatment of wastewater, excreta, and sewage can be classified into two categories – individual wastewater systems (septic tanks and latrines) and collective wastewater systems (sewer and treatment plants). About half of the residents of Yaoundè are connected to the sewer system, while the rest depend on either septic tanks, latrines, or a combination of the two.

Historical population trend, Grahamstown 1840-1980 Historical population trend, Grahamstown 1840-1980
While the white population were the majority in the early period of Grahamstown, South Africa, they were outnumbered around 1920. Historically, the non-white population did not pay for water and sanitation services, and this became a problem when this demographic group became the clear majority.
