Your Comments
from last week.
Lorne,
Be careful
with broad statements like:
water sources
are rapidly being polluted, depleted, diverted and exploited by
corporate interests ranging from industrial agriculture and manufacturing
to electricity production and mining.
There are
many places where there are just too many people living in places
that will not support them. Also, much of the depletion of resources
is possible because of government policy. Many units of government
are more concerned with generating tax base than environmental
impact. I am not on anyone's side, I believe in balance. No one
seems to promote balance. All interests, both public and private,
will need to recognize this in order to sustain resources for
future generations.

1. A Banff
Alberta park employee was backpacking over the Saskatchewan Glacier,
part of the Columbia Icefield. Wading across a speedy meltwater
river that flow along polished channels down the glacier, he slipped
and was swept downstream. The water carried him down a crevasse,
right into the glacier. It was black inside with no light plus
hardly any clearance between the icewater stream he was bashing
down and the jagged ceiling above him. As he was swept further
into the glacier, he was battered about by sharp ice. The ceiling
of ice gradually began to close up around him. Sharp rocks and
ice cut into him as he was carried deeper and deeper inside the
glacier. Somehow, miraculously, he managed to avoid being struck
as he whipped past theses deadly obstacles. After a terrifying
roller coaster ride in total darkness of some 400 yards, he emerged
into daylight on the east side of the Saskatchewan River. He was
cut and bruised and hypothermic, but not seriously injured. He
now works with the United Nations to improve Canadian’s
awareness of the importance of fresh water, including that locked
in glacial ice.

2. WATER IN
THE CITY CONFERENCE
SEPTEMBER 17-20, 2006
VICTORIA, BRITISH COLUMBIA
A Unique Conference...
Water in the
City is a unique conference that will bring together the people
who make decisions about water. Not just engineers and water managers,
but also municipal politicians and staff, senior governments,
the development industry, consultants, the environmental community,
interested citizens, youth, and commercial and institutional water
users from all over North America. We are bringing people together
to take a broad, visionary look at water issues facing our communities
and to explore innovative approaches and practical policy alternatives
necessary to solving these issues. http://www.waterinthecityvictoria.ca/
3. India:
looking ahead to one and a half billion people

If India faces
an acute problem anywhere arising from population growth, it is
likely to be with water. Availability of fresh water does not
change much, although climate change will add some incertainties.19
By the middle of the next century, it will be down to some 1400
m3 per person (simply as a result of population growth), well
below the 1700 m3 per person commonly accepted as the threshold
of water scarcity.20 But current water problems have much to do
with policy and practice.
Agriculture
takes 80% or more of the nation’s fresh water. As water
is largely under priced there is no economic incentive for conservation.
Irrigation water is charged for, but at rates which do not allow
the major irrigation schemes to pay for essential maintenance.
So canal systems are leaky, and a lot of water is simply lost.
Some farmers use too much water and end up with waterlogged land;
some do not get enough. Where water is scarce, such as in parts
of western India, matters have been made much worse by several
things. Most of the water used for irrigation comes from tube
wells. But until recently development of tube wells was virtually
unregulated; those who could afford it dug deeper wells, often
emptying their neighbors’ shallower ones as water tables
dropped. Power and fuel prices have been kept low so that pumping
is too cheap, and water is often over pumped. Crops such as sugar,
which might not even be grown if water was properly priced, bring
farmers high returns. Overall the results have been socially inequitable
and environmentally dangerous.2122 India’s rivers are also
highly polluted by agricultural chemicals and dumping of human
and industrial wastes.23
Urban water
presents a similar picture. A commonly used standard of need is
100 litres per person per day. But better off consumers already
use over 250 litres a day, while the poor make do with 10 litres
or less. Many water users, including the better off with piped
household supplies, pay nothing for their water whereas poor people
often pay for drinking water supplied by tanker.24 As India’s
population grows and becomes more urban, these issues will become
more prominent. Pollution with industrial and human waste is rife.
Coliform bacteria in the river Jumna have been measure at 75 000/l
as it enters Delhi and 3 000 000/l as it leaves.25 Obviously the
availability and quality of water supplies will have an important
effect on health.
Clearly with
better management and pricing policies, India could have done
a lot better and could still solve many of its future problems.
As much as 30% of irrigation water has been estimated to be wasted,
so great potential exists for more efficient use. New plant varieties
requiring less water, shifts to less water intensive crops, and
low cost irrigation techniques would help a great deal. Many low
cost measures for reducing water pollution are available already,
and many more will undoubtedly be developed. Population growth
will add to water needs; whether those needs will be met depends
on technology and on water management all over the country. http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1116811
