Exploring what wetlands do, what we are losing, and what recovery can look like in Punjab
Wetlands are the places where land and water negotiate. They slow floods, clean water, store carbon and feed birds that travel thousands of kilometres. Across the world and across Punjab, they are disappearing quietly.
The widening gap
The Global Wetland Outlook 2025 reports that 411 million hectares of wetlands, about 22 percent of the global total, have disappeared since 1970. The decline continues at 0.52 percent a year. One in four remaining wetlands is already in poor ecological condition.
Chapter 1 · What we are losing
Drainage for farms, urban growth, pollution and dams do most of the damage. Rivers diverted or drawn down for irrigation leave their floodplains dry. Climate change adds heat and irregular rain. The Outlook estimates that losing a fifth of the remaining wetlands by 2050 could put up to 39 trillion US dollars in benefits at risk.
These pressures rarely act alone. A drained marsh is easier to farm, a farmed floodplain is easier to build on, and each step makes the next harder to reverse.
What a living wetland does
A wetland is any place where water shapes the soil and the life above it: marshes, lakes, floodplains, river margins and peatlands. Together they cover about 6 percent of the Earth’s surface, a small share of the planet that does an outsized share of its work. In the monsoon a wetland behaves like a sponge. In the dry months it behaves like a reservoir.
Each type has its own plants, animals and seasons, which is why no single recipe fits all of them.
Reeds and roots filter sediment and pollutants before water moves downstream. Shallow water and wet soil store carbon that would otherwise reach the air. Fish nurseries, grazing land, reed harvests and migratory birds all depend on the same slow, wet ground. Global assessments value the services wetlands provide at more than 7.5 percent of world GDP.
In a province of more than a hundred million people, water that stays in the landscape for a few extra weeks is water that farms, towns and wildlife can all use.

Chapter 2 · Punjab in 3D
Punjab means five waters, named for the Jhelum, Chenab, Ravi, Beas and Sutlej. The Indus runs along its western side. This is the province as a blank model. Keep scrolling and it will fill in layer by layer, or drag it sideways to turn it.
Snow and rain in the Himalayan foothills and the northern uplands feed the Jhelum, Chenab and Ravi, while the Indus and Sutlej arrive from further off. Punjab itself is mostly flat, which is why its rivers spread so wide when they flood.
Most of Punjab’s rain comes with the summer monsoon, roughly July to September, and falls heavily in the north-east and lightly in the south-west. When it comes in a rush, the plain has little room to hold it. The 2022 floods affected about 33 million people across Pakistan.
Pakistan has 19 Ramsar sites covering about 1.34 million hectares, and three of them lie in Punjab: Chashma Barrage, Taunsa Barrage and the Uchhali Complex, all designated on 22 March 1996. Together they cover 42,098 hectares, roughly 0.2 percent of the province. Wetlands and floodplains give moving water space to spread and slow down.
Along the rivers and canals, irrigated fields and riverside woodland form a green ribbon through dry land. Away from them lie scrub and desert. Keep scrolling and watch the green front spread out from the water.
Mountains, rain, rivers, wetlands and plants work as one. Use the buttons to switch layers, or zoom to each wetland.
Province boundary, rivers and elevation are real data. Vegetation and rain are illustrative: they follow Punjab’s known pattern but are not measured. Relief is exaggerated, wetland areas are drawn larger than life so they can be seen, and site positions are approximate.
Chapter 3 · Three wetlands, three jobs
The three Ramsar sites in Punjab are small beside the province, 42,098 hectares in all, but each does a different job. Scroll through them, and select an ecosystem to highlight it on the model.
The largest of the three. A barrage reservoir on the Indus in western Punjab, whose open water and margins serve migratory waterfowl travelling along the Indus flyway. It shows how a working piece of irrigation infrastructure can also hold a wetland.
A stretch of the Indus in south-western Punjab. This reach of the river is one of the last strongholds of the Indus river dolphin, an endangered freshwater species found nowhere else in the world. Flow and water quality decide whether the dolphins stay.
The smallest of the three. A cluster of saline lakes in the Soon Valley of the Salt Range, set in dry hills. Small sites like this matter because waterbirds find few other open lakes in the surrounding landscape.
The models are illustrations of each wetland’s character, not scale maps.
Chapter 4 · Recovery
Chashma, Taunsa and Uchhali sit in different corners of Punjab, yet each recovers in the same way. White arrows show how water flows through them. Scroll to watch all three come back to life, one chapter at a time.
Chashma · Indus
Chashma’s reservoir shows why flow comes first. A wetland that never fills cannot recover, whatever is planted around it. In a canal-fed province, that is a decision about allocation as much as engineering.
Taunsa · Indus
Below Taunsa Barrage, native reeds and trees rebuild the banks and filter runoff, and the Indus dolphin has water to live in. Planting works best when it follows the water, not the other way round.
Uchhali · Soon Valley
Around the salt lakes of Uchhali, farmers, graziers and local councils are the wetland’s best guardians. A buffer of natural vegetation keeps fertiliser and waste out, and local bird counts show whether recovery holds.
Punjab’s three Ramsar sites are a starting point rather than a limit. A wetland is not wasted land waiting for a use. It is infrastructure that already works, protecting water security as much as nature.
None of this needs new inventions. It needs the wetlands already on the map to be counted, funded and kept wet. Three practical steps would build on what the province has.
