The cultivation of crops in buildings (vertical farming) can offer many advantages. For example, by growing crops in layers above one another in empty office blocks, we can achieve sustainable, efficient and fully-controlled cultivation. Ultimately, this can mean no pesticide use, no nutrient emissions, just 2-4 litres of water per kilogram of vegetables, and a 10-20 times reduction in the amount of land required. Energy consumption is still high, but researchers are working hard to grow products using less energy than needed in a greenhouse.
Vertical farming could bring about a revolution in the production of fresh vegetables. By growing crops in layers in a controlled environment, it is possible to provide guarantees on the level and quality of production, every day of the year, and whatever the weather and climate (or climate change).
Growing vegetables in the city
In many cities, there are lots of factories and offices that are currently empty. Using these buildings for vertical farming creates a safe, healthy and sustainable pathway to providing the growing populations of these cities with locally-produced fresh food.
