The coming water scarcity in Africa
In a few years from now, almost all sub-Saharan countries will be below the level at which water supply is enough for all. Even worse, most of them will be in a state of water-stress or scarcity.

Biological oxygen demand - BOD: 1976-2008
The availability of oxygen is one of the most important indicators of the condition of a water body, because dissolved oxygen, or DO, (the amount of oxygen dissolved in water) is necessary for most aquatic organisms, inc...

Trends in capture fisheries and aquaculture
The levelling off of the global fisheries catch reflects a growing decline in most major fishing areas. Today, these fishing areas are producing lower yields than in the past, and it is unlikely that substantial increase...

Suspended sediment discharge
Asia exhibits the largest runoff volumes and, therefore, the highest levels of sediment discharge. Due to their high precipitation, the Oceanic Islands have disproportionately high-suspended sediment loads (Gleick, 1993)...

Renewable surface water produced internally
It is difficult to determine the amount of renewable water produced internally from the total renewable water resources (external and internal). However the FAO gives a rather precise definition of this indicator. Intern...

Trends in global water use by sector
The greyband represents in the difference between the amount of water extracted and that actually consumed. Water may be extracted, used, recycled (or returned to rivers or aquifers) and reused several times over. Consum...

Main world’s river basins
Reservoirs are artificial lakes, produced by constructing physical barriers across flowing rivers, which allow the water to pool and be used for various purposes. The volume of water stored in reservoirs worldwide is est...

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 hum...

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 se...

The WWF living planet index for freshwater
'The over-exploitation and mismanagement of fisheries, particularly when combined with other man-made stresses, can lead to the collapse of regional fish faunas. In many countries, aquaculture is rapidly increasing in re...

Damming the world
The construction of large dams - defined as those with walls at least 15 metres high - has increased significantly over the past 50 years. The average height of new dams, estimated at 30-34 m from 1940-1990, increased to...
