Genetically modified crops
Academics at Harper Adams University in Shropshire are exploring ways to improve the yield of crops during hot dry summers like the one we're currently experiencing.
They're growing wheat in drought conditions and treating some of it with a pine resin product - as a form of "water proofing".

The proposed common rule book could make trading in areas such as US agrifoods more complex, says the University of Southern California's trade expert Greg Autry.
He says: "Having to deal with whatever the current fashion is in Europe, where the Europeans have decided to be afraid of GMOs [genetically modified organism] or some new agricultural technology used in the US makes that process more complex than if we were dealing just head on head with Britain."
