A follow-up to the Rio Earth Summit of 1992, it aims to map
out a concrete set of action plans to reduce global poverty and
the North/South income gap in a sustainable way without
inflicting irreparable damage to the environment.Its guide is the Millennium Development Goals (MDG) laid out
in the U.N.'s 2000 Millennium Declaration. It resolved to halve,
by 2015 the proportion of people who are unable to reach, or to
afford, safe drinking water.
Following are some facts and figures on the state of the
world's water supplies and the U.N.'s goals regarding water.
ACCESS TO WATER
According to the United Nations' 1998 Human Development
Report, three-fifths of the 4.4 billion people in the developing
world lack access to basic sanitation and almost a third have no
access to clean water.
By some estimates, preventable water-related diseases kill
10,000 to 20,000 children every day in the developing world.
COSTS
The World Bank says that to meet the MDG's development
goals, around 300,000 people per day will have to be connected
to water systems over the next 10 years. The estimated price tag
is $25 billion a year.
CONSUMPTION
According to the United Nations, the world's population
tripled in the 20th century, leading to a six-fold increase in
the use of water resources.
The three largest water users in global terms are:
1. Agriculture: 67 percent
2. Industry: 19 percent
3. Municipal/residential: 9 percent.
SUPPLY
Freshwater ecosystems cover less than one percent of the
Earth's surface.
Ice -- mostly in the form of glaciers -- comprises 69
percent of the world's freshwater supplies and groundwater is 30
percent. Wetlands, which include marshes and swamps, comprise
0.3 percent, lakes 0.3 percent, and rivers 0.06 percent.
However, many experts argue that the wells are not about to
run dry. They say that on a global level we have enough water
but must use it more wisely and attempt to address uneven
distribution around the globe which is related partly to
different rainfall patterns.
PROBLEMS/ISSUES
The problems affecting the world's freshwater supplies are
many, including pollution from industry, agriculture and
untreated sewage.
Poor infrastructure is another major issue. According to the
World Wide Fund for Nature (WWF), 30 to 50 percent of water
diverted for irrigation purposes is lost through leaking pipes
and channels.
The World Bank says inefficiencies in infrastructure mean
that water that does not reach customers is not only wasted but
ultimately not paid for. This can lead to infrastructure decay
because of a lack of funding for maintenance and improvements.
Tariffs are often kept low by politicians seeking to woo
voters, leading many to advocate the privatisation of water
services - 95 percent of municipal water services are publicly
run - but this is controversial because of concerns that the
very poor could be denied access as a result.
The advocates of privatisation argue that services will
improve at lower costs as a result because the contracted
operators will have an incentive to improve their product.
DAMS
Dams have brought huge benefits to more than 140 countries
but the social and environmental costs have often been high.
Perhaps 40 to 80 million people have been displaced globally
by dam projects. Dams have damaged aquatic habitats and blocked
migration routes for spawning fish species such as salmon.
According to a 2000 report by the World Commission on Dams,
China and India have half of the world's 45,000 dams. Dams
account for 19 percent of electricity generated worldwide, and
24 countries generate more than 90 percent of their power from
dams.
SPECIES AT RISK
According to the WWF, of the 10,000 species of freshwater
fish that have been described, 20 percent are threatened or
endangered because of pollution, habitat destruction, damming,
over-fishing and the introduction or invasion of alien species.
