Monday is World Water Day, but I suspect relatively few will have noticed.

be sustainably supplied”
While the world is rightly moving to address the challenges presented by climate change and depleting supplies of fossil fuels, the same awareness and consensus does not exist when it comes to addressing our usage of water. Yet the harsh fact is that we will probably run out of water long before we run out of fuel. Read more

Human activities (settlements, industry, and agricultural developments) can disturb the components of the natural cycle through land use diversions and the use, reuse and discharge of wastes into the natural surface water and groundwater pathways. Read more

Did you know…? Facts and figures about water and health (part 2)
Global under-five mortality has fallen from 93 per 1,000 live births in 1990 to 72 per 1,000 in 2005 – a decline of 22.5% – but the pace of progress has been uneven across regions and countries. The decline has been slowest in sub-Saharan Africa.
Malnutrition accounts for about a third of the disease burden in low- and middle income countries.
Lack of access to adequate, safe food, partly related to water resources management, is one cause of malnutrition, but up to 50% of malnutrition is related to repeated diarrhea or intestinal nematode infections as a result of unclean water, inadequate sanitation or poor hygiene. Read more
