Johnny and I went down a rabbit hole to understand Saudi Arabia’s massive farms. Just south of the Saudi Arabian town of Tubarjal, there’s an expanse of farmland that stretches to the horizon and beyond. It’s a baffling 3,000 square kilometers of lush green fields, densely packed into a grid-like pattern. And it’s right in the middle of one of the biggest deserts in the world. Johnny found this place on Google Earth while preparing for a field shoot in Saudi Arabia, and called me with a question: What are these fields doing in the middle of the desert? And how did this country manage to grow so many crops in such an inhospitable environment? Finding the answer took us on a journey through 40 years of drastic change in the desert kingdom.
