Subject: MAGNITUDE/DIMENSIONS OF DROUGHT IN BALOCHISTAN
1. BACKGROUND:
In most basins the springs and tubewell waters are acceptable for drinking and irrigation. The average temperature and precipitation values attribute that climatically Balochistan falls in Mediterranean and monsoonal arid zone. The altitude determines the cool-temperate to tropical temperate regimes. Surface water resources are limited, the groundwater being the only dependable source. Springs, Karezes, dug and persian wells are the traditional means of groundwater utilization. The mechanized system of tubewell installation was initiated in 1960 particularly for serving cultivable and including orchards increasing demand of water. The geology of Balochistan is dominated by five depositional basis, (I) Chagai-Raskoh Volcanic Arc, (ii) Makran-Kharan Basin, (iii) Fold Belt, (iv) Pishin Sub-basin and (v) Sibi Sub-basin. The surface drainage divided these depositional basins into 12 hydrologic/river basins.
The estimated total groundwater
potential of 12 basins for future utilization as calculated by WAPDA during
1983
was 936 Mm3 per year which
decreased to 619Mm3 per year during 1993. The yearly decrease in groundwater
potential in different river
basins vary from 0.18 to 5.3 percent, being maximum in Gaj, Moola and Zhob
river basins
and very limited amount
of groundwater is available for future utilization. The groundwater monitoring
results of
selected basins of Balochistan
show the depletion of groundwater estimates, such that the same for Pishin
river basin
for the period 1989-96 indicates
a continuous decline of water table from 0.2 to 3.5 meters per year.
The Irrigation Department
has worked out the reduction of discharge of some of the perennial irrigation
schemes in
Sibi Division which also
gives a very alarming figure showing reduction of discharge from 1/3rd
to about half. In this
connection Naari Headworks,
Saazo Irrigation Schemes, Sheerani Irrigation Scheme and Qasid Viala Irrigation
Scheme, Gurmi Harnai may
be quoted. Similarly, Kawas Irrigation Scheme and Khan Irrigation Scheme
may be
quoted in Ziarat District
and Chimari Irrigation Scheme and Pazza Irrigation Scheme in Dera Bugti
and Kohlu
Districts respectively where
the water table has gone down substantially.
All these figures present
a very alarming situation of drying down of groundwater reserves and developed
perennial
sources of water in Sibi
Division. In other parts the position is not different. Any way it can
be said that even in the
areas where perennial sources
of water were developed at huge costs with reduction in discharge of half
to less than
one third, the capacity
of the sources to sustain plant animal and human population has reduced
proportionately.
This situation indicates
that even if there is a rain fall in June or July, 2000, the trend is hardly
going to be reversed
and the capacity of the
groundwater reserves and perennial sources of supply to sustain the population
will be
alarmingly low. This sends
signals to work out medium and long term plans for finding out sources
of water supplies
for the animal and plant
population. The sooner a long term plan is drawn for sustenance of the
population the better
so as to a void more serious
catastrophe in future. (Mm3 signifies Million cubic metres and mm, millimeters).
II CONSEQUENCES OF DROUGHT:
- About 8% of the livestock population totally starved to death as the range land spread over 21 million hectares which used to cater for 70% feeding needs for livestock population in this province dried upto the extent of 60%.
- An equal number of livestock turned weak and diseased which needed medical treatment. In all about 10 million livestock population (mostly sheep and goats) forming main stay and source of income for the livestock farmers is required to be provided with concentrates and wheat straw as fodder after drying down of the ………
- The livestock farmers all over the affected areas totaling to two hundred fifty thousand turned destitute as the values of their stock eroded pulling them much below the poverty line with total run down of their purchasing power and now, depend entirely upon relief assistance for their survival.
- The areas severely affected due to drought conditions included the districts of Chagai, Lasbela, Kharan, Khuzdar, Kalat, Killa Saifullah, Loralai and Pishin. The other district like Zhob, Musa Khel, Kohlu and Mastung have been affected moderately while the districts of Killa Abdullah, Jhal Magsi, Bolan, Sibi, Dera Bugti, Kech, Panjgur, Barkhan, Ziarat and Awaran have been slightly less affected. In the district of Quetta, the Tehsils of Panjpai and Kuchlak only have been affected from drought spell. Thus barring the Pat Feeder Canal fed district of Nasirabad and Jaffarabad and the coastal district of Gwadar all the 23 districts of the province have been affected by drought conditions in varying degrees.
- The water table has gone down and discharges from ground-water based under supply system has declined from half to less than one-third.
Owing to variations in geographical,
demographic and topographical situation coupled with groundwater resources
and sources of water supply
in different regions, the actual damages done by drought will vary from
place to place in
the vast landscape of the
province. Studies are required to be conducted on regional basis for proper
analyses of the
situation. However, study
conducted by United Nations Food Assessment Mission in respect of Aranji
Sub-Tehsil
focuses on the trends in
this regard. This study was conducted by the Mission in the last week of
March, 2000. The
findings provide a glance
in the situation which may be summarized as follows:
Due to extended drought conditions
for a continuous period of three years, the drought situation in Balochistan
has
aggravated affecting approximately
a population of 1.5 million spread all over Balochistan who are in need
of relief
assistance on emergent basis.
Livestock being the main
stay of such population, the drying down of grazing land has multiplied
the problems of
feeding the animal population
owned by the affected population. The affected livestock population will
be around 10
million which has been directly
hit by the drought.
The relief assistance will thus be required for the following purposes:-
