KARACHI: A leading rights group in Pakistan has said that seawater intrusion is triggering the collapse of villages and farmlands in the country’s shrinking Indus delta, urging the federal and Sindh provincial governments to launch environmental restoration projects in the region.

The downstream flow of water into the delta has decreased by 80 percent since the 1950s as a result of irrigation canals, hydropower dams and the impacts of climate change on glacial and snow melt, according to a 2018 study by the US-Pakistan Center for Advanced Studies in Water.

That has led to devastating seawater intrusion. The salinity of the water has risen by around 70 percent since 1990, making it impossible to grow crops and severely affecting the shrimp and crab populations and forcing communities to abandon their parched island.

The Sindh Human Rights Defenders Network (SHRDN), which recently organized a visit of members of the civil society to the delta, described the delta situation as a “slow-motion disaster” and called for urgent national and international action to save its environment and inhabitants.

“Release of 25–27 MAF (million acre-feet) water annually into the Indus Delta to push back seawater intrusion and encroachment,” the rights group stated in a set of recommendations for authorities to address the issue.

“Expansion of mangrove plantations and environmental restoration projects, with independent audits to ensure benefits reach local communities.”

More than 1.2 million people have been displaced from the overall Indus delta region in the last two decades, according to a study published in March by the Jinnah Institute, a think tank led by a former Pakistani climate change minister Sherry Rehman.

To combat the degradation of the Indus River Basin, the government and the United Nations launched the ‘Living Indus Initiative’ in 2021. The Sindh government is currently running its own mangrove restoration project, aiming to revive forests that serve as a natural barrier against saltwater intrusion.

Chacha Ghani Katyar, a resident of Dandho Tar where the Indus meets the Arabian Sea, said the sea had swallowed “vast tracts of land” after upstream dams choked off the delta’s lifeline: the annual release of 25 MAF of freshwater promised under the 1991 Water Accord among Punjab, Sindh, Khyber Pakhtunkhwa and Balochistan provinces.

Katyar called freshwater flows from recent floods “a guest that will soon leave.”

The SHRDN demanded federal and Sindh governments address the water flow issue to protect the delta’s ecology and livelihoods.

TEHRAN: Militants killed one policeman in Iran’s restive southeastern province of Sistan-Baluchistan, Iranian media reported Sunday, adding that three assailants also died.

“A policeman from Saravan was killed while terrorists were trying to enter the police station” in that area of Sistan-Baluchistan, the Tasnim news agency said.

The agency said the attackers were members of Jaish Al-Adl (Arabic for ‘Army of Justice’) Baloch militant group, which operates from the borderlands between Iran, Pakistan and Afghanistan, mainly the Sistan-Baluchestan triangle, but active inside Iran.

“Three terrorists were killed and two were arrested,” Tasnim said.

Sistan-Baluchistan, which shares a long border with Pakistan and Afghanistan, has been the site of frequent clashes between security forces and insurgents or smugglers.

The province hosts a significant population from the Baloch ethnic minority, which practices Sunni Islam in Shiite-majority Iran.

On July 26, gunmen stormed a courthouse in the province’s capital Zahedan, killing at least six people, in an attack that was later claimed by Jaish Al-Adl.

In one of the deadliest attacks in the province, 10 police officers were killed in October.
