Threats
There are
various threats and problems to
the water resources and their management
in this region. Some of them can
be enumerated as follows:
- Demand:
According to government estimates,
the population of Pakistan is expected
to grow by 2.1 % over the next 25
years. The population of the Northern
Areas is set to grow even faster,
that is, by 2.5% per annum. This
means that the water availability
for agriculture needs to grow by
at least 30% in the next ten years
just to maintain the present level
of usage per capita. Within the
domestic sector increase in demand
will be higher, that is, almost
50% over the next decade, because
of accelerated urbanization and
increased domestic water usage in
rural communities (GoP & IUCN,
2003). The town of Gilgit itself
is expected to reach almost 200,000
by the year 2020 (Raza, 2002).
Therefore if proper
management of water and development
of additional water resources is
not adequately carried out, there
could be a perceptible shortage
of this resource with serious implications
for the economy of the region.
- Pollution:
Increasing pollution is threatening
the water supply of the region.
This increase is coming from the
pressure of population increase.
As mentioned before, water in the
towns and villages is generally
not potable except where well water
is used or where interventions have
reduced contamination. For example,
two of the major water channels
that are the source of drinking
water to the town of Gilgit have
become open sewers from the effluent
and other human-generated waste
running into it. Here many houses
situated along the water channels
dump their garbage right into the
channels due to lack of proper disposal
facilities.
In rural areas also,
the pollution of water channels
is a problem. Raza (1997) has catalogued
the fecal content of tranditional
water channels in area villages
and this has been discussed earlier
in this report.
Water pollution is
also increasing from increased chemical
fertilizer use in the region. For
example, in the Gilgit district
almost 93% of the farmers now use
chemical fertilizers.
- Less
water for nature: Growth
in water demand not only poses a
challenge to people, but also has
repercussions for the natural ecosystems.
Water abstraction for human use
is already six times greater than
it was 50 years ago. Natural aquatic
systems like rivers, streams and
wetlands could come under stress.
Although there is no data or research
to show how much water is needed
for the health of these systems,
yet there is evidence that the threshold
for sustainable water diversion
may already have been exceeded in
certain areas (GoP & IUCN, 2003).
This, if not checked, could result
in negative impacts on the ecology
of the Northern Areas.
