“DO YOU DO magic tricks?”
It is the villagers. They watch us pass under the blinding white sun of the Thar Desert. We are walking across India with a cargo donkey. Local people mistake us for vagabond performers, travelling quacks, circus nomads. The answer to their question, of course, is: yes. We carry magic. But so does everyone.
It lies in water.
Human beings are mobile wells of mildly salty water. As every schoolchild knows, our bodies contain the same fraction of water—71 percent—as the portion of the Earth’s surface that is covered by oceans. This is no mystery. We are water animals born into a water planet. Water is everywhere and nowhere. It is a restless compound—transitional, unstill, always on the move. It shape-shifts constantly from gas to liquid to solid and back again. (Even frozen at the South Pole into a mile-and-a-half deep cap of ice that is one million years old, it still flows, albeit slowly.) The oceans hold 97.25 percent of all the water on the globe. The poles and glaciers trap 2 percent. The absurdly small, drinkable droplet that remains— the precious 0.75 percent of liquid fresh water that Homo sapiens relies on for survival—we squander like madmen raving in a desert.
In India, a country of 1.3 billion people, fully half the population lives in a water crisis. More than 20 cities—Delhi, Bangalore, and Hyderabad among them—will gulp their entire aquifers dry within the next two years. This translates into a hundred million people living with zero groundwater. Farmers in the Punjab, one of India’s core breadbaskets, complain that their water tables have dropped by 12, 18, or 30 metres in a single generation. A water inheritance amassed since the last Ice Age, across thousands of years, is being pumped out tirelessly by industrial agriculture, by the Green Revolution. The government’s response? Build more large dams (India has 5,000 already) and re-channel the course of rivers to quench the thirst of parched regions. Meanwhile, the vital monsoon rains grow more erratic with changing climate. And demand for fresh water swells by 16 million new human beings a year.
“Conservation? Nobody talks about it”, says my walking partner Arati Kumar-Rao, a nature photographer who has lived among the dry-land farmers of the Thar.

The rain harvesting technology of India’s desert dwellers is ancient and complex. They look carefully at the broad roll of the land, noting gentle depressions called aagor—sky catchments. They channel the scarce rains down these barely perceptible slopes to ephemeral ponds called khadeen. These rain-fed reservoirs they have farmed for centuries, perhaps millennia, without irrigation, growing drought-resistant crops like millet.
Kumar-Rao and I pause at desert well. The sun is toxic. It is 113 degrees Fahrenheit. We are thirsty. I drop a tin bucket through a trapdoor. I hear a splash. I yank up delicious weight on a rope.
“Hah!” a man shouts. “What are you doing?”
He has appeared from a hut. He is a shepherd. This is his rainwater, collected radially, from many sun-cracked acres around, into this hand-dug hole. You can drink what you wish he tells us—this is every traveller’s right—but you cannot wash.

One oxygen atom. Two atoms of hydrogen.
Water molecules are bent like an arrow tip, like an elbow. This gives them a certain polarity, an infinitesimal charge, that collectively shapes the world. They are the magical solvent, binding and dissolving brain cells, mountains, the steam of morning coffee, tectonic plates.
I walk the edge of the Thar Desert.
I pass through villages where changing water use is silently poisoning people. In the past, surface rainwater alone was enough to meet the demands of humanity. Now, modern agriculture and population growth have pocked the land with thousands of bore wells: machine-drilled capillaries whose pumps tap deeply into groundwater. But not all of this once inaccessible supply is healthy. It contains minerals. Fluoride. Arsenic. It varies from place to place. This is half of the crisis—not quantity, but quality.
“Do you know your fluoride level is above safe standards?” my new walking partner, the environmentalist Siddharth Agarwal, asks gathered villagers.

Agarwal, who has trekked thousands of miles along rivers in India, often stops to test the water of village faucets along our route. He uses a device attached to his smartphone that measures fluoride levels. A few drops of water go into a canister. He snaps a photo. The colour of the water, analysed by an app, reveals its mineral content. Excess fluoride causes teeth and bone disfigurement.
The villagers nod somberly. They often know about fluoride. But what can they do? The authorities have promised a filter. While they wait—some have waited years—they buy water delivered by tanker truck. Or they drink the slow poison. Our bodies are living wells. One cannot go without water.
“The most important surface isn’t the one we’re walking on”, Agarwal tells me. “It’s the water layer below our feet”.
He views landscape through this X-ray prism. The trees change, the crops change, human life changes, all depending on the wet topography below. A vanishing liquid underworld.
Weeks later, crossing the brackish Sambhar Lake basin near the city of Jaipur, I watch women at work. They earn three dollars a day. They walk blindly backwards for hour after hour, raking up salt across a vast plain of scorching white. Heat-bent light swallows their legs, delivers them back. An infernal vision. Some sorcerer’s bitter abracadabra. But it isn’t. It is us.
