It took the world less time than expected to make the journey from adapting to climate change to dealing with a climate emergency. The only way to fight it, experts agree, is to work together. This is especially true in densely populated regions like South Asia, home to about one in four people in the world.

Pakistan and India are the only two nuclear-armed nations in the Hindukush region that have fought four wars, but are in immediate need of climate solutions with 2022 being a tipping point for the neighbouring countries.

While Pakistan experienced the worst flooding in its recorded history affecting more than 33 million people, India faced successive droughts and heat waves pushing it to the bottom tier of the Global Hunger Index (GHI).

“These concerns are overlaid by changing demographics in India and Pakistan, increased urbanisation, and rising demands on the agricultural and industrial sectors,” says Medha Bisht, senior assistant professor at the Department of International Relations at South Asian University, New Delhi. “This has contributed to making both countries, particularly Pakistan, among the most water-stressed in the world.”

While world leaders made pledges at the 2022 UN Climate Change Conference in Egypt, experts in the two nations said there are implementable solutions closer home.

Indus Water Treaty post-2016

Before the British left the subcontinent, the large contiguous land mass that is now Pakistan and India were served by the Indus river and its tributaries. In the wake of the Partition and subsequent mass migration — the largest in the world — the leaders of these countries negotiated a treaty under the World Bank’s supervision.

The Indus Water Treaty gives India control over the waters of the three “eastern rivers” – the Beas, Ravi and Sutlej, while Pakistan controls the three “western rivers” — the Indus, Chenab and Jhelum.

The treaty has survived wars, skirmishes and international conflicts between the two countries over the disputed region of Kashmir, from where the rivers originate. But, climate emergencies threaten to break what wars could not.

2021 parliamentary report by New Delhi worries climate change is largely ignored by the treaty, which was agreed upon based on the knowledge and” ‘technological imperatives” available at the time it was negotiated, the 1950s.

Climate observers in India say ineffective water usage and climate emergencies have made the region a tinderbox. A smallest spark is all that is required.

In 2016, an Indian Army brigade headquarters in Uri town of disputed Kashmir was attacked, killing 19 soldiers. India blamed Pakistan, a charge Pakistan denied. Islamabad believes any disruptive activity in disputed Kashmir is indigenous.

An unintended casualty of the attacks was water sharing between the two countries. Prime Minister Narendra Modi of India declared “blood and water” cannot flow together.

While the treaty was not breached, India revived hydel power projects on the eastern rivers that lay dormant until then. Projects such as the 800MW Bursar hydroelectric project on the Marusudar river, one of the tributaries of the Chenab, in the Kishtwar district of disputed Kashmir and the Shahpur-Kandi project in the Gurdaspur district of Punjab were re-started.

Azeem Ali Shah, a Lahore-based researcher with the International Water Management Institute (IWMI), told “A unilateral withdrawal from the treaty will bring World Bank into the dispute. It will also incite further anxiety among Pakistani people and might lead to violence.”

Pakistan’s Indus Water Commissioner Syed Mehar Ali Shah said the country expects better information flow between the two countries. For instance, early warning signals on floods would help the country combat such emergencies, he said.

Water-intensive agriculture

When Pakistan and India have bilateral disputes over water, they have tended to revolve around hydro-power projects and rationing water. Concerns around water quality or effective use remain largely ignored. As a result, the treaty has become about quantitative water sharing as opposed to qualitative and effective use of water.

2021 collaborative study between researchers from Pakistan and India found the countries have slightly different priorities. Pakistan prioritised information on floods, water quality, minimum environmental flows and exploitation of groundwater with the absence of a regulatory mechanism. Indian priorities also included reflection on cropping patterns, shifting water tables and shifting river course and water quality.

While the Indus Water Treaty looks at the macro perspective on water governance between the two countries, there are micro-narratives on water diplomacy.

“These are livelihood narratives,” said Bisht. These are about local communities effectively using water for their lives and livelihoods. “It is time to capture such narratives,” she said.

One of the main challenges for water usage across South Asia, and especially in Pakistan and India, is the water-intense form of agriculture,” writes Omair Ahmad, managing editor for South Asia at The Third Pole.

“In both these countries most of the water, around 80 percent, is devoted to growing crops. More importantly, much of this water is simply wasted. Both of these countries use a form of rice cultivation in which the crop is grown in standing water, and much of this water simply evaporates. More problematically, large amounts of water are transported through leaky canal structures over long distances, evaporating on the way, and ending up diverting far more water than is actually needed to grow the crops,” he notes.

The way forward — indigenous methods of water use

Experts say indigenous water management techniques used across the region may help capture and preserve more water.

Among these is the centuries-old Rajaki in Hunza Valley, which is a community-based piping network designed for high-altitude terrains that can be found in Pakistan’s north and northwest. In Hunza, the locals build pipes that are designed to supply villages with water from high-altitude glaciers. Locals deem it a communal technique since it unites the entire community in ensuring that not only does every village nearby and their households get their share of water, but also that water wastage is minimised to further ascertain better supply and usage.

Another centuries-old water management method, common in Balochistan, is Karez. The well-like vertical shafts are interconnected through tunnels, which transport subterranean water to the surface. The vertical tunnelling system has long ensured that water reaches the surface without any manual or mechanical pumping. The Karez system not only significantly reduces the energy being expended on transporting water, but it also reduces water losses via evaporation, making the technique especially useful in hot and dry climates.

Karez too, like Rajaki, has historically required collective community maintenance allowing water management to be used as a means of societal adherence, which helps address conflicts in volatile regions like Balochistan — something that both Islamabad and New Delhi can learn from.

In the upper reaches of Jammu and Kashmir valley, locals use a method to collect water from melting glaciers. They call it Zing. These are small man-made tanks that collect water melted from the glaciers during the summer months. They use it in other seasons.

In 2019, the government of Indian Punjab submitted a rainwater harvesting plan. 70 percent of the population depends on groundwater for drinking and irrigation purposes, so they needed to revert to traditional methods to ensure there was enough groundwater for a rapidly-growing population.

Observers like Bisht say only more dialogue between the civil societies of the two countries will bring about lasting positive changes. “This is the reason why water sharing alone cannot become the focus of the relationship,” she said. “Water management should be the way forward,” she added.
