Farming Without Soil in the Tropics: How It Really Works

This Video is from the Youtube channel: “Agrotonomy”. 

We visited Jamaica Tower Farms, where over 100 aeroponic towers are growing basil and lettuce in the heart of Kingston. This vertical farm is addressing one of the Caribbean’s most pressing issues: dependence on imported food.

In a country where droughts are becoming more frequent and farmland is limited, these towers offer a highly efficient solution. They use 95% less water and 90% less space than traditional farming methods, without requiring any soil. This makes them particularly well-suited for tropical climates like Jamaica's.

Jamaica imports over 60% of its food. Droughts, hurricanes, and soil degradation make traditional agriculture unpredictable and increasingly unsustainable. Aeroponic systems offer a reliable alternative. They eliminate soil erosion, drastically reduce water usage, and provide year-round crop production.

This farm primarily grows basil and Batavia lettuce, along with other leafy greens and herbs. Every crop harvested locally reduces the island’s reliance on international imports, lowers the carbon footprint, and ensures fresher, more affordable food is available to communities that need it most.

Despite its lush appearance, Jamaica loses an estimated 400 million tons of topsoil each year due to erosion. This vertical farming approach avoids that entirely and enables food production without degrading the land.

This farm is a clear example of how climate-smart agriculture can work in the Caribbean. As extreme weather events increase and urban areas expand, solutions like this will play a critical role in achieving regional food security.
