Why Are Rice Fields Flooded? (Not for the Reason You'd Think)

That sheet of water covering the rice fields every spring hides a small secret — and gives northern Italy one of its most poetic sights.

There's an image that returns, right on schedule, every spring in northern Italy. Flat fields stretching all the way to the horizon, covered by a thin veil of water that, at dawn, catches the pink of the sky and gives it back untouched. It's like seeing the world twice. These are the rice paddies — and almost everyone, standing before that mirror, thinks the same thing: that rice, in order to grow, needs to live underwater.

And here's the surprise: it doesn't.

Rice isn't an aquatic plant. It would grow perfectly well in dry soil, exactly like wheat or corn. So why flood the fields? Because that water, in the end, isn't there for the plant — it's there for the people who grow it. It's one of the most ingenious gestures in all of agriculture.

The main reason is weed control. Rice tolerates standing water far better than the weeds that grow alongside it: flood the field, and the weeds "drown" while the rice carries on undisturbed. A natural herbicide made of nothing but water — which is why, for centuries, flooding was the heart of this crop, long before any chemical existed. And there's more: that thin layer of water also works as a thermal blanket. It soaks up the heat of the day and releases it slowly at night, shielding the plant from temperature swings and late frosts.

But it's when you step away from the explanation that the paddies reveal their true nature. Nowhere is the sight more breathtaking than in the Po Valley. Few people know it, but Italy is Europe's leading producer of rice — on its own, it accounts for nearly half of all the rice grown on the continent — and its heart beats between Vercelli, Novara, and Pavia, where the fields vanish into the distance. When they're flooded in late spring, they become the famous mare a quadretti, the "checkerboard sea": a mosaic of still mirrors that at dawn look like a single sheet of glass, and that shift color all day long with the sky — silver in the morning, gold in the evening, and on the horizon, always, the rose-tinted snows of Monte Rosa.

And that water has already lived a long story before it ever arrives. It's born high up, from Alpine snow melting slowly, and makes its way down through a network of canals that monks, in some cases, dug centuries ago — a hydraulic choreography drawn by hand, patient, perfected over hundreds of years. Every spring, that same water returns to fill the same fields, like a ritual handed down through generations.

And it's from this land made of water and light that the rice in our Pasta Gustosa is born. It's the rice that gives it that tender bite and its unmistakably Italian character — without a single grain of wheat. Because some things, even when they're "free-from," stay deeply, unmistakably Italian.
