As World Water Day is approaching, UNESCO
released the "World Water Resources Development Report" on the 13th,
pointing out that global water consumption increased six times in the 20th
century, and its growth rate was twice the population growth rate. The report
points out: "Our ability to meet the continuously growing global water
demand will depend on people's effective management of existing
resources." The report raised nine issues worthy of attention.
1. Water resources management, system
construction, and infrastructure construction are all insufficient: Although
the earth’s freshwater resources are unevenly distributed, they are still
sufficient. However, poor management, lack of resources, environmental changes
and insufficient investment in infrastructure mean that about one-fifth of the
world's people do not have access to safe drinking water, and 40% of people
lack basic sanitation facilities. With the current situation and the speed of
improvement, it will be difficult to achieve the United Nations Millennium
Development Goal of halving the number of people without safe drinking water by
2015.
2. Poor water quality leads to poverty and
poor sanitation: In 2002, about 3.1 million people died of diarrhea and malaria
around the world, of which nearly 90% were children under the age of 5.
Approximately 1.6 million lives each year could be saved by providing safe
drinking water and sanitation.
3. Water quality is declining in most
areas: There is evidence that the diversity of freshwater species and
ecosystems is declining rapidly, often faster than terrestrial and marine
ecosystems. The report points out that the water cycle on which life depends
requires a healthy development and operating environment.
4. 90% of natural disasters are related to
water: Many natural disasters are the consequences of improper land use. The
increasingly severe drought in East Africa is a painful example. Local people
have cut down forests to produce charcoal and fuel, causing soil erosion and
lake disappearance. Due to overdevelopment around it, Lake Chad has shrunk by
nearly 90%. The report points out that shrinking water resources will trigger
various adverse natural reactions.
5. The contradiction between agricultural
water supply and demand has become more tense: By 2030, global food demand will
increase by 55%. This means more irrigation water is needed, which already
accounts for nearly 70% of global human freshwater consumption.
6. Urban water shortage: By 2007, half of
the world's population will live in cities. By 2030, the proportion of urban
population will increase to nearly two-thirds, resulting in a surge in urban
water demand. The report estimates that 2 billion people will live in
shantytowns and slums. Lack of clean water and sanitation hits these urban poor
hardest.
7. Insufficient development of water
resources: More than 2 billion people in developing countries do not have
access to reliable energy, and water is an important resource for creating
energy. Europe develops and utilizes 75% of its hydropower resources. However,
in Africa, 60% of people still do not have access to electricity, and the
development rate of hydropower resources is very low.
8. Serious waste of water resources: In
many parts of the world, as much as 30% to 40% or more of water is wasted due
to leaks and illegal connections in pipes and ditches.
9. Financial investment in water resources
lags behind: The report points out that official development assistance for the
water sector has averaged approximately US$3 billion per year in recent years,
and financial institutions such as the World Bank will also provide US$1.5
billion in non-concessional loans. However, Only 12% of funds are spent on
those most in need, and only 10% of aid funds are used to develop water
resources policies, plans and programmes. Additionally, private water sector
investment is on a downward trend, making it more difficult to improve water
efficiency.
