Political economy of water resources
(March 15 2004): It
appears that the next fisticuffs would be fought
over water, especially in South Asia. The conflict
of Kashmir is actually the dispute of water. Both,
India and Pakistan are assaying to get the control
of the two rivers Jhehlum and Chenab.
No doubt, water is important for both the
countries because these being agrarian societies.
Water is the lifeblood of agriculture, whether in
the form of rain and snow, or running rivers, or
amassed in the earth's belly.
Pakistan is blessed with water wealth. Prudent
management is needed to turn this wealth into
gold. In the country's total area of 803,940 sq
km, water is on 25,220 sq km. Pakistan has three
main river basins: the Indus, the Kharan and the
Mekran.
The Indus Basin forms the largest river basin with
fertile plain lands in Punjab and Sindh provinces,
while the Kharan and the Mekran water
Balochistan's plains. The Indus and Mekran basins
drain off in the Arabian Sea. The Kharan Basin is
known as a closed basin because the entire basin's
catchment water is used in agriculture and in
domestic requirements.
In spite of abundant water resources, we are
failing to manage these resources. The two related
issues are power production and agricultural
development. If these problems are resolved, we
shall be able to set up a launching pad for
economic development. We shall have to manage
these resources for their efficient use.
Pakistan produces only 28.2 per cent of the total
electricity by water resources and the remaining
71.8 per cent is generated through expensive
resources (68.8 per cent by fossil fuel and 3 per
cent by nuclear resources). Hydro electricity is
the cheapest of all other resources, why do we
fail to capitalize on water resources by proper
management? Agriculture contributes only 24 per
cent share of our total GDP, whereas 72 per cent
people are affiliated with agriculture.
Pakistan depends on irrigation and water resources
for 90 per cent of its food and crop production.
The vast irrigation system comprised of three
major storage reservoirs, 19 barrages or head
works, 43 main canals with a conveyance length of
57,000km, and 89,000 watercourses with a running
length of more than 1.65 million km.
This vast irrigation system feeds more than 40
million acres of irrigated land in Pakistan, a
country with the highest irrigated and rain-fed
land ratio in the world (4:1). In spite of the
world's largest irrigation system, the cultivable
land is not used to its full potential because
most of the areas in Balochistan, Sindh and
Southern Punjab are still joggled by water
shortage. Even in areas where well-defined
irrigation system is accessible, the agricultural
lands are bereft of optimum quantity of water.
A few days ago the officials of the Irsa announced
that the discharge of water from river Indus has
decreased by 30,000 cusec, forcing the authorities
to cut Punjab's share by 15.8 per cent and for
Sindh by 9.4 per cent. It would never have
happened, if we had launched proper water
conservation and management policies.
The only solution to all these problems is proper
water resource management and efficient use of
water resources by constructing new dams, silt
drainage of existing dams and canals, cleaning of
water channels, stopping of water seepage,
controlled water discharge etc.
The first step here is new dams; all other
management practices rise after the construction
of new dams. New dams are our need. It is
surprising that some political leaders are flying
the flag of political interests rather than the
national interests. The three dams Kalabagh,
Bhasha and Skardu would resuscitate barren lands
by water. The government should not dally with
these projects.
The feasibility report on Kalabagh dam is ready
and if the government starts work on this project
immediately, it will be completed till 2010. Water
will be stored in 90 miles long gorge in front of
this dam, unique in construction.
The most part of the silt and mud will
automatically be drained by water flow. For
drainage water level will be kept up to 825 feet
from start of June to July 21. If this reservoir
is filled up to its full storage capacity, it can
generate 36,000 MW of electric power. Even in June
when the level of water will be kept minimum for
drainage purposes, it may produce 463 MW of
electric power.
During the drainage period of Kalabagh dam,
Terbela dam will be filled up to its full storage
capacity, so alternate drainage practices will be
carried out in both dams to maintain constant
supply of power and water. Annually, 11,413
million units of electric power will be generated
by Kalabagh Dam and due to alternate drainage
periods, the capacity of Terbela dam to generate
electricity will be increased by 336 million units
annually.
The feasibility report of Bhasha dam is being
completed. It will take some months and after
completion it will be put before experts in July
2004 for detailed debate. If the government starts
work on Bhasha dam in 2006, it will be completed
in 2013.
A dam in Skardu (Katzara) is the third option. In
the south of Skardu, there is a natural gorge
which is perfect for dam construction. This place
is pretty useful to store water from the three
rivers Indus, Shewak and Shaegar. With the
construction of this dam, almost 35 MAF water can
be stored and 15,000 MW of electric power can be
produced by the flow of stored water.
The construction of new reservoirs is of utmost
need because the silting storage capacity of both
Mangla and Terbela dams is decreasing day by day.
It will be decreased by 5.94 MAF till 2010.
Problems concerned with these reservoirs can be
resolved by consensus. Water logging may be a
problem in some areas of the NWFP because of
Kalabagh. Sindh fears decrease in water quantity
in the Indus river due to water storage in
reservoir.
Sindh thinks that due to the lack of water in
Indus river, the aquatic creatures may disappear
and there is also a threat to natural vegetations
(e.g., mangroves) near the coastal areas.
The people of Sindh also feel that the stored
water in reservoir will mostly be used by Punjab.
All these problems are just assumptions, nothing
else. Adequate compensatory measures can be
applied to erode the fear of unfair water
distribution, depletion of aquatic creatures and
natural vegetations.
Compensatory measures may be adopted by holding
seminars on community level, participatory
decision-making, alternatives to the affected
persons, etc. Problems related to the Skardu dam
is its height of area (7,000 m from sea level),
which is so difficult to have easy access,
installation of electric power lines, power
losses, effects on air base, effects on
agriculture and trade and the alternative
residence of the community.
These problems can be solved by appropriate
planning framework that needs devoted efforts and
spirit of sacrifice and services by both
government and community.
