GOJAL VALLEY, Pakistan, March 29 (Thomson Reuters Foundation) — Shovel in hand, Naila Shah regularly walks two miles from her home to a newly planted apple orchard, high in the mountains of Khyber village in northern Pakistan.

Only two years ago, it would have been practically impossible to grow apples in this part of Pakistan, 2,500 meters (8,200 feet) up in Gilgit-Baltistan region's Gojal Valley.

Although the Khunjerab River provides plenty of water to those living in the valleys below, local farmers used to have no efficient way to get it up the mountainsides.

But the installation of a hydraulic ram (hydro-ram) pump has changed that. It harnesses the pressure of fast-flowing water, such as a river, to drive a share of that water uphill without needing any other power source.

Because the pumps work without electricity or fuel, they are cheap to run and produce no climate-heating carbon emissions.

"Previously, we used to survive on rainwater," said Shah, a teacher and secretary of a local women's development group.

"The land used to be barren, as water couldn't be lifted from the river flowing right next to the area," she said, digging out weeds from around the bases of young trees.

Low-cost, sustainable irrigation systems like hydro-ram pumps could be key to helping Pakistan's mountain communities adapt as climate change drives more severe droughts and floods across the country, environmental experts said.

"The government cannot afford larger irrigation systems," said Haider Raza of green group WWF-Pakistan, which installed the pump in Khyber village two years ago under a project led by the International Centre for Integrated Mountain Development (ICIMOD).

"But these high-efficiency irrigation systems, which aren't an expensive technology, can be used to improve the livelihoods of local communities," he told the Thomson Reuters Foundation.

Encouraged by the results, the United Nations Development Programme gave WWF-Pakistan additional funding to install 20 more hydro-ram pumps in 12 villages.

Each pump is connected to a drip irrigation system that delivers a steady, gentle flow of water to mountain-top crops, using less water than many traditional irrigation methods.

The pumps have helped revive about 60 acres (24 hectares) of previously barren land, benefiting nearly 300 households, Raza said.

Their simple design — consisting mainly of pipes and two valves — means few moving parts to maintain or repair.

Upkeep of the pumps, which cost up to 70,000 Pakistani rupees ($430) to build and install, is easy and affordable for communities, who have welcomed the new systems, Raza added.

Moving Monsoon

Seeing the potential for low-cost irrigation to help mountain communities, Pakistan's government last year approved funding for the Gilgit-Baltistan water management department to install 50 hydro-ram pumps, along with 150 solar-powered pumps.

Those systems should help irrigate 1,050 acres of orchards in nearly a dozen districts, according to Mudassar Maqsood, associate programme coordinator at ICIMOD.

The government's efforts to bring water to high-altitude communities may also get a boost from nature itself.

Climate experts predict shifting rainfall patterns in Pakistan could in future move the wet season away from its southern and central plains to northern mountain regions.

Muhammad Irfan Tariq, who recently retired from his post as director general of Pakistan's climate change ministry, said the plains might eventually get less monsoon rain than they do now.

That could lead to a drop of up to 15% in the country's wheat harvest, he noted, without specifying a time frame.

"Climate change is affecting the agriculture sector now and will continue to do so in future," he said.

'Golden Opportunity'

If the rains keep moving north, that could increase pressure on mountain farmers to grow more grains like wheat and rice, said Ali Tauqeer Sheikh, former CEO of Leadership for Environment and Development-Pakistan, an independent thinktank.

But that would be a mistake, he warned.

Trying to replicate the conditions of areas like Punjab in the mountains would put too much strain on the higher terrain and could lead to more flooding in the plains below, he said.

"The Hindu Kush Himalayan region of Pakistan is a highly fragile ecosystem and if it gets destabilised due to unsustainable practices, the frequency and intensity of downstream disasters will increase," he said.

Pervaiz Amir, director of the non-profit Pakistan Water Partnership, said mountain farmers should instead focus on crops that are suited to elevated altitudes.

"Higher rainfall in this mountainous region offers a golden opportunity to grow high-value crops such as cherries and apples that can lead to greater profits," he said.

For Shah and the other women farmers in her community, that golden opportunity may have already arrived with a simple pump system that enables water to flow uphill.

To bring in some money as they wait for their apple trees to mature and bear fruit, they have planted potatoes and peas in the spaces between the trees, Shah said.

"In the beginning, the work was difficult, as the land was barren and there was no water," she said. "(Now) the land has turned green."
