KARACHI: The number of migratory birds arriving in the wetlands of Pakistan's Sindh province has declined by nearly 15% compared to last year, according to the Sindh Wildlife Department on Saturday, raising alarm among conservationists about the impact of water scarcity and climate change on critical habitats.
A recently completed 'Annual Waterfowl Survey' for the 2024–25 season recorded 545,258 migratory waterbirds at 30 major wetland sites across the province. The data show a 14.68% drop from the previous year's count of 639,122 birds, with both surveys covering around 40% of Sindh's total wetland area.
'The apparent reason for the decline in migratory bird numbers is the decrease in water bodies, as these migratory waterfowl are associated with wetlands and the availability of natural food therein,' Javed Ahmed Mehar, Conservator at the Sindh Wildlife Department, told Arab News.
'We plan to conduct a detailed study with relevant stakeholders to determine the causes of this decline [with greater certainty],' he added.
Wildlife photographer Shahbaz Alam, who has documented Sindh's lakes and marshlands extensively, also attributed the drop to drying wetlands.
'These birds spend their day in the water, searching for food, and then move toward greener areas,' he said. 'With Sindh facing severe water shortages and the drying of wetlands due to climate change, the habitat is simply vanishing.'
Describing the situation as 'very alarming,' Alam said he had also noticed the decline over the years.
'Where we once saw thousands [of birds], we now see only hundreds,' he told Arab News.
Pakistan has 19 wetlands designated as Ramsar sites under the Ramsar Convention on Wetlands, an international treaty named after the Iranian city where it was adopted in 1971. The convention aims to conserve globally important wetlands and promote their sustainable use.
Together, these Pakistani sites span 1.34 million hectares. More than half are located in Sindh, including Keenjhar Lake, Haleji Lake, the Indus Delta, Jubho Lagoon and the Rann of Kutch. These wetlands have long served as critical stopovers for migratory birds traveling along the Indus Flyway, an avian route from Siberia and Central Asia.
Among the worst-hit areas this season was the Rann of Kutch Wildlife Sanctuary, which witnessed drought-like conditions, while Nareri Lagoon in Badin hosted the largest number— 155,068 birds.
According to Rasheed Ahmed Khan, who led the survey, the decline is directly related to the decrease in rainfall and the reduction of water bodies and wetlands.
'Due to a severe lack of rainfall last year, almost all dams in Tharparkar remained dry. If reduced rainfall continues due to climate change, there could be a significant decrease in the future,' he warned.
The survey team, comprising experts from the Sindh Wildlife Department and Zoological Survey of Pakistan, recorded over 57 species of migratory waterfowl. These included prominent sightings of Common Teal, Northern Shoveler, Indian Spot-Billed Duck, Cotton Pygmy Goose and Lesser Flamingo.
Endangered species like the Great White Pelican were also documented, highlighting the region's ecological significance.
