Businesses are transforming rooftops, courtyards, parking lots, and unused land into working farms, growing their own food to reduce reliance on suppliers and serve fresher meals.

At the JW Marriott Grande Lakes in Orlando, guests are often eating produce grown just steps from where they’re staying.

Farmer-in-residence Leslie Wilber oversees the hotel’s on-site farm, where a wide variety of crops are grown throughout the year.

The sun, the sand, the sea breeze–these are homegrown in Turks and Caicos. But the ubiquitous resort buffets? Much of the food is imported, often resulting in lackluster quality.

Not so at Seven Stars Resort & Spa, where the name of a new restaurant, The Farm, says it all. Wanting fresh produce, but faced with the challenge that most of the island’s foundation is limestone with little to no soil, Executive Chef Edwin Gallardo established a hydroponic container farm—the first on the island.

The resulting bounty of fresh vegetables—an estimated six tons of produce per year—not only guides the menu, but also the hotel’s ambitious sustainability initiatives. An underground cistern captures nearly 7 million gallons of rainwater annually, reducing water usage, and Seven Stars is also phasing out plastic cups, bottles, and straws, and implemented water stations with glass and metal refillable bottles.
