Are we using dripping technology, anywhere?
Rehman is among a growing number of farmers in Pakistan who are turning to water-saving drip irrigation and sprinklers, which agricultural experts say can support yields in regions where seasonal rains are no longer a reliable source of water.The method helps farmers use 60pc less water
Dripping technology can save us the coming times with extreme water shortagesYes.

Drip irrigation system getting popular due to rising water shortage

MARI: Obaidur Rehman hoped to grow water-hungry cucumbers and capsicum peppers on land he had bought in an arid area of eastern Pakistan — but the available water wasn’t sufficient for traditional irrigation.
So the 56-year-old farmer tried something new: A drip irrigation system, supported by a government initiative.
The system delivers small amounts of water only where needed, and has helped him get higher yields on his farm near Mari than on flood-irrigated land he owns elsewhere in Punjab.
The switch, besides allowing him to farm with 60 per cent less water, has cut the fertiliser he needs in half as less is washed away and wasted, Rehman said.
“Drip irrigation has come as a divine help to me in this arid area,” he said, sitting in a shed on his farm.
Rehman is among a growing number of farmers in Pakistan who are turning to water-saving drip irrigation and sprinklers, which agricultural experts say can support yields in regions where seasonal rains are no longer a reliable source of water.
Farmers flood their fields to irrigate their crops, said Pervaiz Amir, director of the Pakistan Water Partnership (PWP), a non-governmental organisation.
A nine-year government effort to cut water waste, launched in 2012-2013, has so far helped 7,000 small-scale farmers make the move to water-efficient irrigation, said Malik Muhammad Akram, head of the Punjab Agriculture Department’s water management programme.
Over the past 30 years, Pakistan has gone from a country enjoying an abundance of water to one facing increasing water stress.
Between 1990 and 2015, the amount of water available per person dropped from just over 2,170 cubic metres to about 1,300 cubic metres, according to a 2017 report by the United Nations Development Programme.
That was the result of rapid population growth, urbanisation, industrialisation and water-intensive agricultural practices, combined with growing climate impacts, the report said.
Agriculture today contributes about one-fifth of Pakistan’s GDP, according to a study published last year by the World Bank. But Muhammad Arif Goheer, an agriculture expert at the Global Change Impact Studies Centre in Islamabad, a climate change think-tank, said changing patterns of monsoon and winter rains are a big problem for rain-fed farms in arid areas.
Increasingly, farmers either do not get rain when they need it or get too much rain when their crops need dry conditions, he said.
But access to water-efficient irrigation can give farmers in arid regions a reliable water source and also allow them to grow high-value crops, such as olives and grapes, that often require more water, Goheer said.
The Punjab government’s Rs67.5 million ($407,300) project provides subsidies for small-scale farmers to install sprinklers and drip irrigation systems, some using solar power to run them.
With the motto “more crop per drop”, the Punjab Irrigated-Agriculture Productivity Improvement Project, run in partnership with the World Bank, aims to have new irrigation systems installed on 120,000 acres of farmland by next year.
Akram, of the agriculture department, said that so far 66,000 acres of land have been switched to water-efficient systems.
Nearly half of that was barren land that has been put back into use as a result of the project in three water-scarce areas, Potohar, Thal and Cholistan, he said.
Work has already started on converting another 11,000 acres of land over to new irrigation methods, he added.
On average, drip irrigation and sprinkler systems use at least 50 per cent less water than flood irrigation, Akram said.
But sprinklers and drip irrigation do not work for all farmers, noted Amir of the PWP.
After farmers lay the pipes for the irrigation systems, they must remain undisturbed for four or five years because digging them up and moving them is so expensive, he explained.
With vegetable and orchard farming, farmers can leave the pipes where they are, but for other popular crops, like rice, wheat and cotton, pipes need to be removed for ploughing and land preparation prior to each new crop, he said.
