How do the United Arab Emirates and neighboring Saudi Arabia try to become self-sufficient with a shortage of fresh water and a lack of fertile agricultural land? Mega greenhouses, dairies and poultry factories are located in the middle of the desert, where water is scarce. Saudi Arabia not only wants to be self-sufficient, but also to become the largest exporter of agricultural products in the region. Water-saving solutions, such as closed greenhouse systems and innovative irrigation, make it possible to produce more and more food locally. These latest techniques, professionals and knowledge are purchased abroad. Much of this knowledge comes from the Netherlands.
