ISLAMABAD, Pakistan (Thomson Reuters Foundation) – Zulekhan Mumtaz has seen her livelihood as a seller of camel milk turn sour because of a brutal heat wave that left Pakistan sweltering for three weeks in May with temperatures up to 51 degrees Celsius.

“My customers say they can no longer buy spoilt milk and squander their money,” the 31-year-old said, looking at the clotted yellow liquid.

“How can I buy fodder for the camel and food for my two children if the heat wave damages my milk?” she asked, resting with her animal in the shade of a tree in an upscale residential neighbourhood of Islamabad.

Pakistan in recent weeks has suffered its most severe heat wave in decades, with temperatures reaching as high as 51 degrees Celsius (124 Farenheit) on May 19 in Larkana, a city of two million people in southern Sindh province. This was the highest temperature for that month recorded there since 1998, when the mercury had peaked at almost 53 Celsius (127 Fahrenheit).

Lahore, Punjab province’s capital of about 15 million population, was the hottest city in the country on May 24 at 47.4 Celsius (117 Fahrenheit), hotter than any May since 1954.

Such extreme temperatures – which are becoming more common as a result of climate change – are an enormous health threat. They also make almost every function of daily life a nearly intolerable struggle – including, for millions, trying to earn a daily living.

The camel milk vendor Mumtaz, who lives in a shanty village on the outskirts of Pakistan’s capital, walks about four miles (6.5 km) daily to set up her roadside stall. Most of her customers are diabetes patients, among whom camel milk is very popular because it is a good source of insulin to help deal with the illness.

But “the heat wave has eroded my livelihood and made my camel sick because of frequent dehydration,” Mumtaz said, adding that the animal’s milk capacity had dropped by 70 percent. She sees her only remaining option as leaving the capital to return to her ancestral village.

Other livestock owners in Chak Shahzad, an area on the edge of the city popular with cattle farmers, report similar problems.

FEARS OF HUMAN, LIVESTOCK DEATHS

In the final week of May, Jamal Khan sold all 19 of his buffalos to a slaughterhouse in the city for about 2.1 million Pakistani rupees ($21,000), because his herd’s daily milk production had declined by 60 percent.

“I had no choice but to sell them, for fear of suffering heavy losses if they die of hyperthermia or repeated bouts of dehydration,” Khan said.

Deaths have not been limited to animals. Although officially confirmed figures of heat-related deaths are not available, local newspapers in Pakistan reported over a hundred deaths since early May.

Residents in most cities, towns and villages have been forced to stay indoors, leaving typically bustling shopping areas and business centres closed, and roads and highways deserted between 10 a.m. and 6 p.m.

Left with limited options to cope with the heat, people have increased their consumption of cold beverages and fresh juices to try beat the sizzling heat and avoid dehydration and heat stroke.

Government hospitals across the country remained on emergency alert throughout much of the last month because of the heat wave.

“We have been advising the visiting patients (to increase) consumption of fresh water, juices, fruits and vegetables”, said Altaf Hussain, executive director of the Pakistan Institute of Medical Sciences Hospital in Islamabad.

On May 27, rainfall finally brought a significant drop in temperatures to below 38 Celsius (100 Fahrenheit) in the Pakistani provinces of Khyber-Pakhtunkhuwa, Gilgit-Baltistan, Punjab and Balochistan.

But the Pakistan Meteorological Department (PMD) predicted dry and very hot weather across the plains of Sindh province, in the south of the country, for the first week of June. Temperatures in Islamabad have rebounded by 10 degrees to 40 Celsius  (104 Fahrenheit) since the end of the month.

According to a meteorological department advisory, the heat wave is unlikely to completely loosen its grip until the beginning of the first monsoon rains, expected in the first week of July.

Qamar-uz-Zaman, vice president for the Asia region at the World Meteorological Department, said that extreme summer temperatures, which have become common during the last few years in Pakistan, can largely be attributed to climatic warming.

CROP LOSSES

Data gleaned last year from 56 meteorological stations throughout Pakistan show a marked increase over recent years in the frequency of heat waves and rising temperatures particularly in the southern plains and coastal areas, according to Ghulam Rasul, a senior weather scientist at the meteorological department.

Reports of severe damage to cotton crops and paddy rice nurseries have come from around the country.

Ibrahim Mughal, chair of Agri Forum Pakistan, said in a phone interview that the heat wave had struck when cotton and rice sowing were at their peak.

“Farmers will have to quickly re-sow their cotton and paddy crops to avoid further harvest losses,” Mughal said.

Pervaiz Amir, an agro-economist and member of the government’s Task Force on Climate Change, said that the heat wave increased the evaporation rate by 20 to 25 percent compared to normal summers. He advised farmers to irrigate their crops more frequently, at least once or twice a week, and to adjust the timing of irrigation to early mornings and late evenings.

He also urged planting of shade and fruit trees along water channels, to cut evaporation of water.

Pakistan’s Environment Protection Agency warned that people in urban areas are at greater health risk from heat waves than those in rural parts of the country, in part because urban areas often absorb more heat.

Early warning technology protects Nepali villagers from sudden floods

JHIRPU PHULPINGKATTI, Nepal (Thomson Reuters Foundation) – For years, Deepa Newar and her neighbours lived with the fear that their livelihoods – and even their lives – might be swept away without warning.

Newar and her fellow residents of Jhirpu Phulpingkatti, a village some 112 km (70 miles) northeast of Kathmandu, Nepal’s capital, live perched on the bank of the Bhote Koshi River. The river is prone to sudden, devastating floods that can swamp fields, carry away livestock and even kill those who do not manage to flee to higher ground.

The 2.5 acres (1 hectare) of land on which Newar cultivates paddy rice and maize have suffered severe flooding four times in the last 32 years, most recently in 2011.

Looking at the swirling grey waters of the river that flows into Nepal across the border with China’s Tibet Autonomous Region, 10 km (6 miles) upstream, the 39-year-old recalls those disasters.

“(The river) left behind a trail of death and destruction whenever it has turned into a monster,” she says.

But Newar now enjoys a sense of safety for herself and her family, thanks to an early warning system for floods installed by the Bhote Koshi Power Company (BKPC) at its hydropower plant on the river.

GLACIAL LAKE THREAT

Flash floods can be caused by severe storms or the failure of levees, but the Bhote Khosi River is also susceptible to glacial lake outburst floods. These result from the catastrophic failure of a natural dam high in the mountains that contains glacial meltwater. Such failures are becoming a greater risk as warming temperatures linked to climate change lead to faster glacial melt and greater volumes of water in the lakes.

The Bhote Khosi river basin covers an area of about 3,400 square km (1,300 square miles) and has an estimated 150 glaciers. Of its 139 glacial lakes, whose area totals some 16 square km (6 square miles), 59 are highly vulnerable to outbursts, according to a study conducted by the International Centre for Integrated Mountain Development (ICIMOD), an intergovernmental body of eight countries in the Hindu Kush-Himalaya region, including Nepal and China.

In 1981, a glacial lake outburst flood in the river basin washed away several bridges, including the China-Nepal Friendship Bridge along the Araniko Highway, said Pradeep K. Mool, a glaciologist at ICIMOD in Kathmandu.

Until 2010, floods could strike the villages with no warning. Residents had virtually no time to move to higher ground and were forced to leave behind their livestock and crops, suffering financial losses as well as emotional distress.

“Before the advent of the warning system … we were at risk of being washed away,” said Newar.

Janak Raj Pant, maintenance manager at the Bhote Koshi power plant, said that the river is subject to erratic flows, particularly during the monsoon. For this reason, the power company arranged for the early warning system to be installed in 2010 to benefit the downstream communities in Sindhupalchowk district.

5 TO 8 MINUTES WARNING

The early warning system gives villagers 5-8 minutes’ notice of a flood – just enough time to save themselves.

Five flood sensors are positioned near the Nepal-China Friendship Bridge, about 6 km upstream from the power station.

If the water in the river reaches a dangerous level, the sensors activate sirens placed at four locations, including one at the power plant. The sirens warn the communities to flee to higher ground. Residents use their mobile phones to warn other villages further downstream.

According to Pant, a glacial lake outburst flood takes about five minutes to travel from the Nepal-China Friendship Bridge to the plant. He says lives can be saved if people respond to the alarm immediately.

“At present, the warning system can make the sirens blare five minutes before any flood can strike any of the 79 downstream villages of Sindhupalchowk district,” said Pant, standing beneath the red siren mounted on a side wall of the company’s building.

According to Pant, it is not currently possible to give more warning because information on flooding is not available from the Chinese side of the border.

About 40 percent of the Bhote Koshi river basin is in Nepal, with the remaining 60 percent in China.

Other residents of Jhirpu Phulpingkatti agree that the system has given them a sense of security, but they would like the lead time given by the alarm to be extended.

More sensors need to be placed further upstream within Nepal, especially at glacier snouts and where glacial lakes have formed or are forming, commented Joydeep Gupta, a New Delhi-based journalist and expert on South Asia river basins and flood warning systems.

NEED FOR CHINESE HELP

The ICIMOD study shows that Nepal has experienced at least 24 glacial lake outburst floods. Of these, 14 are believed to have occurred in Nepal itself, and 10 were the result of flood surge overspills from the Chinese side of the border. According to data from the Nepal Meteorological Department, such floods occur on average once every three years in Nepal.

The glaciers in the Hindu Kush-Himalayas are retreating, which scientists believe is the result of climate warming. As glaciers melt, the water released into lakes can build pressure on the natural dams and increase the risk of an outburst flood.

“We have already sought proposals from interested firms to expand the warning system to other vulnerable districts (near) the Bhote Koshi River,” said Pant. “It is hoped that in coming months we should be able to install alarm systems in as many districts as possible.”

“(The) Nepali government should also replicate and establish such early warning systems at all streams to (avoid) or reduce loss of lives or damage,” said Gupta.

But priority should be given to the streams emanating from the unstable glacier lakes identified by ICIMOD in its recent study, he emphasised. According to Gupta, China, as the upstream country, should collaborate with Nepal to share information about flash floods or glacial lake outburst floods hours before they reach the Nepali border, to allow maximum time for warnings to vulnerable downstream communities.

“Any viable information-sharing system by which Chinese officials can pre-inform their Nepali counterparts of any risk of flash flood or (glacial lake outburst flood) would be very helpful. A similar system between China and India already saved many lives in a flash flood in the Sutlej river area a few years ago,” he said.

Seas may rise 10 yards during centuries ahead

Sea-level rise is currently measured in millimeters per year, but longer-term effects of global warming are going to force our descendants to measure sea-level rise in meters or yards.

Each Celsius degree of global warming is expected to raise sea levels during the centuries ahead by 2.3 meters, or 2.5 yards, according to a study published Monday in Proceedings of the National Academy of Sciences.

The world is currently trying (and failing) to reach an agreement that would limit global warming to 2 degrees Celsius. Business-as-usual practices could yet raise temperatures by 4 (or even more) degrees Celsius.

Multiply 2.5 yards by 4 and you are left with the specter of tides that lap 10 yards higher in the future than today. That’s 30 feet, the height of a three-story building. For comparison, the seas rose less than a foot last century.

The suspended particles present in air on motorway form atmospheric nuclei which by combination with water lead to fog formation.

Vehicular pollution is responsible for fog formation on the motorway in Pakistan.Scientist in Peshawar say that particles coming from vehicular pollution form nuclie which in turn on combination with water present in the air for fog.This fog is a big hurdle for traffic on the motorway in Pakistan.This fog is also responsible for throat irritation,drop in visibility and results in accidents and closure of the motorway.

Principal Scientific Officer Shahid Faruq informed in his radio interview that the chemicals present in the fog in the presence of light rays react and lead to photochemical reactions and their products are skin sensitive. These vehicular pollutants and their products also contribute to green house effects and climatic changes.

GHG and cfc are the main causes of global warming.In Pakistan vehicular pollution has increased along with other forms of pollution.

Principal Scientific Officer pointed out that the gas emission from vehicles and cfc are the main causes of global warming and climatic change.Industrial pollution is adding to air,water and soil pollution and all these lead to climatic change.The gases form a shield around the globe and contain heat energy weather, albedop ,emitted or reflected from any other source and so the temperature increase which is changing the routine rains ,melting the ice and also polluting the surface and ground water.If these are not controlled and the energy sector is not made environment friendly we must wait for deadly out come.
