Experts in Sri Lanka fear that despite the increased frequency of extreme dry seasons, the country still lacks measures to ease the impact on vital sectors like agriculture, energy and water resources. Ranjith Punyawardena, chief climatologist at the Department of Agriculture, said that this year’s main paddy rice harvest was likely to shrink by 7-10 percent due to the shortage of rainfall. – http://www.trust.org/item/20140214194424-vmupo/?source=hptop

[KATHMANDU] With weather becoming more erratic every year as a result of climate change, Nepali farmers are progressively shifting their approach, turning vast areas of rice paddies into small-scale vegetablefarming. Vegetables are more resilient as they can be hand watered in case of drought. Farmers say that with rains that used to come in April now shifting as late as mid-June, vegetables that can be sown at the time the rains finally fall are now a better investment.
But large parts of their fields now remain uncultivated due to lack of water.
The situation raises concern among experts, who warn that a shift from rice to vegetable cultivation may harm food security. They also say that without adequate support from the government farmers’ livelihood could be at risk. According to researchers, there is now a need for insurance schemes, public subsidies and improved early-warning systems to forecast extreme weather.

Pakistan’s mountain farmers struggle with erratic weather
Farmers in north Pakistan valley welcome warmer climate, experts fret

KARIMABAD, Pakistan (Thomson Reuters Foundation) – In the mountains of northern Pakistan, some farmers say rising temperatures are giving them bumper harvests, even as climate and agricultural experts worry about the consequences of warming for the glaciers that are vital for the country’s irrigation.
“Many years back, the weather used to remain cold and cloudy most of the year. But now we have (more) warm months that are helping our staple, cash and fruit crops to grow faster and longer, and post higher yields,” said Sultan Khan, a farmer in Karimabad, a village in the picturesque Hunza valley of Gilgit-Baltistan province.
Farmers in Hunza say maize never used to grow taller than 3 feet (1 metre) during its five-month season (June to October). But a longer growing period and warmer days are helping the stalks reach up to 7 feet (2 metres). The maize yield has increased by an estimated 20-25 percent, they add, and harvests of other crops are also bigger.
Nonetheless, farmers in this remote area also complain that a lack of government guidance has left them uncertain as to whether to adjust their planting schedules to take advantage of the earlier onset of summer, since they do not know if the changes in weather patterns are permanent.
The Hunza valley perches on the north side of the Hunza River in the Upper Indus Basin, some 675 km (420 miles) from Islamabad, Pakistan’s capital. The valley lies at an elevation of around 2,500 metres (8,200 feet) and is surrounded by much higher mountain peaks and glaciers.
Ali Madad, a 76-year-old farmer in Barashal village, said that because of warmer temperatures, glaciers are melting more consistently, which makes his livelihood easier. “Now the streams, which are a major source of irrigation for mountain agriculture, flow even in winter,” he said.
Whereas snow used to begin falling in the valley around mid-October and continue for six months, it now begins in late December and ends a couple of months later, he added.
Temperatures that would fall as low as minus 16 degrees Celsius a dozen years back now rarely drop below minus 2 degrees. Summer, previously a three-month season, has become correspondingly longer, Madad said.
In Karimabad, Sultan Khan observed that winter snowfall is now less than 5 inches, in sharp contrast with the 13 inches or more typical a decade ago.
Local agriculture expert Fida Karim said only the mountain peaks now get covered with snow in winter, while the middle and lower latitudes hardly receive any snowfall. Rakaposhi, a spectacular peak in the Karakoram mountain range and the twelfth highest in Pakistan, has not been completely covered in snow since 2008, he added.
According to Karim, over the last five years, the winter snowfall in the valley has melted in just a few weeks in March. It used to remain until at least the end of April.
The changes experienced by farmers in the Hunza valley are different from those happening elsewhere in Gilgit-Baltistan. In other parts of the province, the winter season both begins and ends later than it used to, delaying the snow melt needed for irrigation and stunting the growth of crops.
But even in the Hunza valley, the changes in the onset of the seasons are a problem for vegetable and fruit farmers like Shehla Hayat.
“Every year in October, the shift from summer to winter used to be gradual. But for the last four years each October, hotter summer days (have) become cooler abruptly,” the 35-year-old farmer said, while harvesting fodder outside her house in Barashal village.
The sudden plunges in temperature, together with unexpected rainfall, have badly affected local crops of apples, apricots, pears and potatoes when they were nearly ripe, causing losses for farmers, Hayat said.
GLACIER MELT FEARS
Climate and agricultural experts warn, meanwhile, that the long-term consequences of the rising temperatures and glacial melt could be dire.
Inayat Karim, a mountain farming conservationist at the Baltit Rural Support Organisation in Hunza valley, said the Ultar glacier, which looms over Karimabad to a height of 7,400 metres (24,300 feet), has been shrinking since 1999, and a previously snow-covered peak is now bare.
Shahana Khan of the Aga Khan Rural Support Programme said the valley now receives rain as well as snow in the winter months.
“This points to a scary scenario for sustainable flows of the Hunza River,” Khan said, pointing out that declining snowfall will eventually reduce levels in the Hunza River, which accounts for 25-30 percent of the water that flows into the Indus River – in turn vital to much of the nation’s agricultural economy.
There are short-term problems for the Hunza River too. Farmers say it has become increasingly turbulent in recent years due to increased glacial melt in the summer months, which sometimes causes it to breach its banks.
The director general of the Pakistan Meteorological Department, Arif Mahmood, is concerned by the retreating snowline in the high mountains.
“In the past, mountains in the valleys like Gilgit, Hunza, Skardu and Shigar in the Upper Indus Basin (UIB) used to receive huge snow in their lower altitude areas, between 2,000 and 3,000 metres. But this is no more the case,” he said.
“There has been a surge in heat wave incidences in UIB areas,” Mahmood continued. “The temperature now goes up beyond 40 degrees Celsius in summer as compared to (an earlier) maximum of 28 degree Celsius some 10 years ago.”
There has also been an unusual shift in monsoon patterns, which are becoming heavier and moving to higher altitudes, he added.
Mahmood warned of increasing flash floods and landslides in the UIB region if temperature increases continue.
The senior weather official called for urgent action to make public infrastructure more climate-resilient, such as strengthening river banks and bridges, and to introduce new crop varieties. Otherwise, local communities will be increasingly threatened by torrential rains, floods and wildfires, he warned.
Pakistan’s mountain farmers ‘helpless’ in face of erratic weather

DANYORE, Pakistan (Thomson Reuters Foundation) – One night was all it took for Bibi Baskiya’s fortunes to be reversed. In June the young farmer had sown maize on half an acre of land in Danyore, a scenic mountain village in northern Pakistan’s Gilgit-Baltistan province.
On Sept. 12 it was sunny and the skies were so clear that Baskiya watered her crop from a nearby spring, certain there would be no rain. But that night, her hopes of a good harvest were destroyed.
“A sudden rainstorm and heavy winds flattened 80 percent of the standing crop,” she said. The maize is now only good to be used as fodder for her cattle, and she will not recover the cost of cultivating it.
Baskiya is one of many farmers in this remote region whose livelihoods are threatened by the effects of erratic weather and climate change. Experts say measures are desperately needed to help them adapt to unreliable rainfall, but few – if any – are available so far.
“We farmers are really helpless before the inconsistent weather,” said Baskiya. “We are thinking to abandon growing maize and wheat, and cultivate cash crops like tomato and potato instead that are short-duration and less water-intensive.”
Maize is the most important summer crop after wheat in northern Pakistan’s Upper Indus Basin (UIB). The grain is harvested to eat, while the stover (dried stalks and leaves) is used to feed livestock during the winter.
“Owing to erratic weather patterns, the area under the staple crops in most of Gilgit-Baltistan province in UIB has shrunk alarmingly, and vegetables are now being grown as cash crops,” said Asmat Ali, director of the province’s agriculture department.
An estimated 70 percent of the wheat consumed locally must now be imported from Punjab province in eastern Pakistan and Sindh in the south, Ali added.
Cash crop farmers are also suffering the consequences of extreme weather.
Ali Da’ad, 50, a vegetable farmer in Danyore, said his potato and tomato crops have been struck by lightning several times.
“There has been a significant escalation in lightning activity and thunderstorms over the last 10 years, particularly during summer months,” Da’ad said.
The lightning has triggered fires, damaging crops and endangering populated areas. At the same time, rainfall is increasingly unpredictable, causing crops to fail.
“In Gilgit district, rains are no longer even and fall patchily during the summer months,” Da’ad explained. “Sometimes it is intense and sometimes not.”
Muhammad Iqbal, chairman of Local Support Organisation Danyore (LSO-D), a nongovernmental group working for rural development, said rains are unequal even within Danyore village. “When it rains in the eastern part of the village, the west remains without it,” he said.
DELAYED SNOW MELT
Gilgit-Baltistan is home to the world’s largest frozen water reservoir, which feeds the Indus river system – a lifeline for Pakistan’s agro-based economy.
Farmers in the province depend on melting snow from April onwards to replenish streams, enabling them to sow seasonal vegetables and maize from late May. But Da’ad said prolonged winter weather is causing the snows to melt later, making it difficult to plant crops in time.
Nek Parveen of LSO-D said this year streams filled 50 days later than expected.
“Women wheat farmers in Sultanabad village (adjacent to Danyore) suffered substantial financial losses early this April, as they had to prematurely harvest after farmers sensed (the crop’s) growth had halted,” Parveen said.
According to Ghulam Rasul, a scientist at the state-owned Pakistan Meteorology Department in Islamabad, rainfall in the province has become less frequent but more intense over the past 50 years.
The decrease in winter precipitation and snowfall due to rising temperatures in the area is affecting Pakistan’s hydrological cycle and hampering the country’s agricultural growth, Rasul said.
“Investing in farmers’ climate adaptation capacity building and knowledge development can help them cope with impacts of climatic variability on their crops,” said LSO-D’s Iqbal.
HARD TO REACH
Iqbal sees a need for the construction of small or medium-sized reservoirs in the foothills and plains, so that water from streams can be harvested for use during the dry season and the winter, both for farming and domestic purposes.
But there has been little progress in the province so far, where development agencies are hampered by the inaccessibility of much of the terrain, political inertia, and a volatile security situation due to conflict between Shi’ite and Sunni Muslim sects.
Jamil Uddin, who manages programmes in the Gilgit region for the Aga Khan Rural Support Programme (AKRSP), said his organisation plans to introduce climate mitigation and adaptation measures for the province’s farmers.
“Our experiences show that information-sharing programmes for mountain farmers and communities about better, proven adaptation and mitigation measures can enable (them) to cope with the aftermath of rapidly occurring climatic variability,” he said.
The AKRSP hopes to bring climate-resilient crop varieties and water conservation technologies to farmers.
According to LSO-D’s Iqbal, transmitting weather forecasts via FM radio and free SMS texts on mobile phones would help farmers, who now rely on indigenous techniques that are increasingly inaccurate as weather patterns become harder to predict.
Iqbal emphasised that helping mountain farmers adapt to the impacts of climate change is vital to support the livelihoods of rural people and maintain an acceptable level of food security.

Ladakh Invites New Scarcities
LADAKH, India, Sep 24 2013 (IPS) – The Ladakh of today is a different world from the one Skarma Namgiyal remembers as a child. Back then, he had taken for granted the breathtaking beauty of its landscape, the purity of the cold mountain air, and the sweet taste of water in its streams.
Today, at 47 years of age, this resident of Tukcha village in Leh district in the north of Kashmir cannot believe they are digging borewells for water, using water to flush toilets in their homes in place of the dry toilets they had been accustomed to, and having to cope with sewage flowing right up to their houses.
Climate change, booming tourism and modern practices are wreaking havoc in this high altitude cold desert in India’s Jammu and Kashmir state. The average elevation in Ladakh is 11,000 ft above sea level and temperatures swing between minus 35 degrees Celsius in winters to 35 degrees in summer. Annual rainfall in the region is less than four inches.
Earlier, water from the melting glaciers would be enough to cater to the needs of the locals, Namgiyal tells IPS. But with less snowfall and warmer summers, some of the glaciers have vanished altogether while others too are fast melting.
“Look at Khardongla,” says Namgiyal’s neighbour Tsering Kushu. “It used to be a huge glacier. It is not there anymore.”

Early warning technology protects Nepali villagers from sudden floods
Thomson Reuters Foundation – Wed, 22 May 2013 10:45 AM
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.
