More than 30,000 hectares of land are covered in plastic, a geometric labyrinth five times the size of Manhattan, where 3.5m tons of vegetables are produced every year from tomatoes to cucumbers, peppers to courgettes, aubergines to melons, enough to feed half a billion people and generate a turnover of more than 3bn euros.
We have deployed several types of cooling systems here, each one used depending on climatic conditions. The system, created millennia ago but updated for the 21st century, works by cooling water underground in the naturally low temperatures at night. To cool water more quickly, some is also sent to the roof via solar-powered pumps and sprayed out of nozzles in a thin layer through a method known as a falling film, before draining back down underground.
Where multi-story apartment buildings are now being constructed once stood the Butcher family orchard. The farm had been in the family since 1881, when Rolla and Emma Butcher bought 160 acres of land. After Rolla's early death, Emma ran the farm by herself, planting fruit trees while raising her young children.
Every morning I join a group of friends for coffee and conversation at a cafe in my neighborhood. We call ourselves the "coffee klatch." This time of year, one of the key klatchers, Michael Soriano, often comes bearing a bag of Meyer lemons, picked from his tree. Last year he even did a drive-by in front of my apartment, delivering a bag of those fragrant golden orbs just for me. Such luxury! And free. It felt like a heist.
