Western Water Battle Lines Being Drawn
Canadians should pay attention to what is happening in
Alberta. There are now limitations to water resources and competition is
being forged between industry, people and ecology.
The Oil and Gas Industry in Alberta uses 7% of all water allocations in
the province. It also uses 37% of the groundwater. Water is primarily used
in tar sand development to separate out the bitumen (tar oil). It takes 2
to 4.5 barrels of water to produce one barrel of oil. The result is
massively polluted water that cannot be returned to ecosystems, but which
must be kept in tailing ponds and effectively removed from the local
hydro-geologic cycle.
Consider this: Canadians consume more water per capita than any other
country, with the exception of the US. According to the Government of
Canada, each Canadian uses 335 L of water each day. Alberta is no
exception and ranks just below the national average in water use. Water
use in Canada has increased by over 25% per capita since the mid 1980’s.
There are other factors in this equation: geography and ecology. Alberta
is located in the rain shadow of the Rocky Mountains system. This means
that as air masses are uplifted over the Rockies precipitation falls on
the west side of the mountains leaving the east side, Alberta, relatively
arid. This is no surprise to most, but the aridity of Alberta has led to
massive wild fires this summer. So we have our third player, the boreal
forest ecosystem that requires water.
The competition continues to grow. The Tar Sands Industry plans to
increase its production threefold by 2025. They will require twice the
amount of water now annually consumed by Calgary. This will lead to a
massive diversion of water from the Athabasca and, potentially, the
Mackenzie River. Yet, in order to meet these production targets, they will
require more people, who will also consume more water. The boreal
ecosystem is the loser in this equation. But the forest ecosystem is the
only player that reduces evaporation rates, cleans the water and can
prevent erosion or other side effects. But forests without development are
not worth much money compared to the tar sands.
Are we still prepared to destroy our children’s and grandchildren’s lives?
Has our greed and desire for all the creature comforts brought us to this?
China’s Challenge to the Environment
August 30, 2006
“The Rise of China” is a phrase most have become
familiar with in recent times. In the early 1990’s China took advantage of
a sluggish world economy by increasing its manufacturing 15% each year,
becoming a world leader. In the last two decades, China’s population has
aspired to consume products at levels on par with rich capitalist
countries. Economists may view this rise with trepidation, but for
environmentalists the viewpoint is different, but no less alarming.
Instead of supposing what role Canada will play in the new world order,
the question becomes, will China dominate economically before its ecology
collapses?
In 2005, the US National Intelligence Council predicted that by 2020,
China would be vying for economic supremacy with the US. However the size
of the population alone -1.3 billion- impedes the ability of China to
reach levels of affluence that are comparable with western capitalist
countries. For instance, were every person in China to own an automobile,
the world supply of steel and aluminium would be exhausted. Much more
immediate needs, such as food production for such a large population are
quickly approaching ecological thresholds.
In 2001, it was determined that the water table under the North China
Plain was rapidly dropping due to the depletion of the aquifer in order to
meet irrigation needs. The region is responsible for producing half of
China’s wheat and a third of its corn. In addition to this potential
collapse of agricultural capacity, the Three Gorges Dam project will
displace 1.6 million and flood 30,000 hectares of prime agricultural land.
To compensate for the threatened areas, China’s forests are being rapidly
depleted to replace lost farmland.
As population pressures ecosystems, so do energy needs. 80% of China’s
energy is derived from coal-fired generation and plans are in place for
another 544 plants. The massive release of carbon dioxide will most likely
accelerate the rate of global warming, which will in turn put pressures on
agricultural production in China. In order to maximize production while
under pressure, China will presumably become increasingly dependent upon
chemical fertilizers as well as pesticides.
All factors combined point to where economists rarely tread, an ecological
crisis. In the future a more realistic question posed about China will be
not about its might, but rather about it’s ability to feed itself.
