The Timeless Legacy of the Indus River in Sindh

The Indus River — one of the world’s great rivers, flowing some 3,000 kilometres from the Tibetan plateau to the Arabian Sea — has been the lifeline of Sindh for thousands of years. Everything the region has ever been flows from it: its first cities, its wealth, its poetry and its food. Its historical importance is deeply connected to ancient civilisations, trade routes and the rich culture of the region, and the story of the river around Sukkur and Rohri is a microcosm of that entire history.

Ancient Civilizations: Birthplace of Urban Innovation

The Indus Valley Civilisation, one of the earliest urban cultures on earth, flourished along the river around 2500 BCE. Cities like Mohenjo-Daro in present-day Sindh — barely a hundred kilometres downstream of Sukkur — were architectural wonders with advanced drainage systems, granaries and far-flung trade networks. The river was crucial for agriculture and served as a major route for transport and communication, enabling trade with Mesopotamia and the Gulf. Our article on the Indus Valley civilisation timeline in Rohri and beyond sets out how this landscape fits the wider story, while the Stone Age workshops of the Rohri Hills show that the region’s industry is older still.

Trade and Commerce: The Lifeline of Prosperity

Throughout history the Indus has been Sindh’s great highway. In the medieval period it connected the interior of Sindh with Central Asia, the Middle East and the sea, and its strategic importance attracted empire after empire — the Mauryas, the Kushans, the Arabs, and later the Mughals all sought control of its banks to dominate the lucrative trade routes. The river ports were the prizes: Aror, the ancient capital, rose on the river’s eastern bank, and when the water shifted away from it, medieval Rohri inherited its trade, growing rich enough to be called one of the great commercial cities of the Islamic world. Fortresses on islands in the stream — above all Bukkur (Bakhar) between Sukkur and Rohri — guarded the traffic and taxed it.

Cultural Heritage: A Source of Inspiration

The Indus has inspired countless poets, artists and musicians. Celebrated throughout Sindhi folklore and literature — most famously in the verses of Shah Abdul Latif Bhittai, whose singers still perform at his shrine — the river symbolises life, fertility and continuity. Its gifts shape daily culture too: the palla fish of Rohri, which runs up the river each season, is both an economy and a beloved emblem of Sindhi identity. Festivals and rituals centred on the river, from boat races to shrine fairs beside its banks, highlight its key role in the spiritual and cultural life of the people.

The Modern Era: Barrage, Bridges and Irrigation

In the modern era the river was tamed and put to work. The Sukkur Barrage, completed in 1932, raised the Indus at the city and fed seven canals that irrigate roughly ten million acres — the foundation of agriculture in Sukkur and Sindh as it exists today. Across the same water stand the Lansdowne and Ayub bridges, engineering landmarks in their own right. The river around Sukkur is thus one of the most engineered stretches of the Indus — a living museum of waterworks, seen at its best from the city’s riverfront, as described in the Sukkur city guide.

Challenges: Floods, Pollution and Climate Change

For all its benefits, the river remains a force that cannot be fully controlled. The super-floods of 2022 drowned a third of Pakistan and pressed hard against the barrage; the November 2024 floods in Sukkur and Rohri showed how urban drainage failures compound the danger even away from the main channel. Alongside flooding, the Indus faces pollution from untreated urban and industrial waste, over-extraction of water for irrigation, siltation and the shifting course that destroyed ancient Aror a thousand years ago. Climate change, by making both droughts and extreme rain events more frequent, raises the stakes every decade.

Conservation for Future Generations

Efforts to preserve the Indus are under way at several levels: provincial and federal water-management reforms, wetland and barrage upgrading, campaigns against industrial dumping, and community-level river clean-ups. Protecting the river is inseparable from protecting its heritage — the archaeological sites on its banks, the crafts of its boatbuilders and fishermen, and the memory of the civilisations it carried. The timeless legacy of the Indus is not a relic; it is a working system of water, farms, cities and culture that will define Sindh’s future as surely as it defined its past.
