(Dawn) The Pakistan Meteorological
Department (PMD) has again warned the government to prepare for extreme drought
conditions in the southern parts of Pakistan, particularly Sindh and
Balochistan.
The most recent warning
came in March this year and was updated in May about less than normal summer
monsoon rains that could also reduce crop yields.
“We are likely to have 30
to 60 per cent less monsoon rains. Pakistan has experienced 11 such episodes in
the past,”
said Azmat Hayat Khan, the director of the PMD, explaining how a
deficient monsoon could significantly impact agriculture and life pattern,
particularly in Sindh.
The weather expert
explained that such drought conditions occurred in the region when the
temperatures in the Pacific Ocean increased, a phenomenon known as the El-Nino
effect.
According to the PMD, some
of the worst drought events occurred in 1969 when rainfalls decreased more than
90 per cent and in 1987 and in 1991 by over 75 per cent.
In 2002, there were 90 per
cent less monsoon showers causing some of the severe droughts in the country.
These predictions were also
confirmed by the South Asian Climate Outlook Forum which in its report forecast
a weak June to September monsoon for large swathes of Pakistan, India and
Bangladesh this year.
The forum, a sub- regional
climate outlook body of the World Meteorological Organisation (WMO) dedicated
to specific monsoon predictions and outlook needs of countries, also warned
that the deficient summer monsoon could affect agriculture-based economies in
South Asia.
The director general PMD,
Arif Mahmood, had initially rejected the weather prognosis as wrong but then in
May his office updated information on its website and issued an alert of severe
drought that could hit southern Punjab, Sindh and Balochistan.
Former member of the prime
minister’s task force on climate change, Pervaiz Amir, believed that if the
forecasts were correct the country was in for difficult times.
“If the southern
half of the country, which is a major sowing area for vegetables as well as
cotton, rice and sugarcane, get below normal rains the productivity of the
cereal crops in both rain-fed and irrigated areas will receive a severe blow,”
he said.
Mr Pervaiz, who studied
agronomy at the Michigan University in the US, added that it could also render
Pakistan unable to achieve production targets for summer crops.
According to the expert,
high temperatures and dry conditions in May and June meant that evaporation of
water in the country’s irrigation network and farmlands was very high,
especially in the southern parts of the country.
“The monsoon rain plays a
crucial role in reducing the evaporation and meeting the water requirement of
crops in the rain-fed areas, particularly in the northern parts of the
country,” the expert explained.
The rainfalls for the
northern parts of the country are no better either with just normal rains,
according to the PMD.
Azmat Hayat explained how
the northern parts, including Islamabad, would have a few good episodes of rain
and that isolated heavy rains can cause flash flooding risks.
