Globally, greenhouse cultivation is increasing rapidly, according to a new study from the University of Copenhagen that maps the global extent of greenhouses. But the majority of this boom is happening outside of Europe, it is taking place in low- and middle-income countries in the Global South.

Their mapping shows that greenhouse cultivation – whether it takes place in glass houses or open fields wrapped in plastic films – covers at least 1.3 million hectares of the Earth's surface. The new figure is nearly three times more than previous estimates.
