since countries in middle east got money enough to build skyscrapers, they should build some greenhouses for farming food too

according to media, building a skyscraper costs on average 550 million dollars 

building a greenhouse costs 25 dollars per square foot 

a lot of oil producing countries in the middle east builds a lot of skyscrapers in their cities, but not so many greenhouses, 

which is odd, since middle eastern countries would benefit from producing more of their food and importing less of their food 

growing wheat, potatoes, rice, vegetable and fruit in steppe and desert areas is likely difficult, but could become very efficient with the use of greenhouses 

greenhouses protect from wind, dust, insects, too much sun, heat and loss of water and green houses can be built large enough that tractors and similar farming equipment can be driven inside them 

farms in greenhouses can get fresh water from desalination plants by the sea powered by solar panels 

vertical farms can still be built in the cities, producing vegetables and berries 

there are already large enough markets so that products such as greenhouses, vertical farms, solar panels and desalination plants are produced by different companies in differen countries
