Global Food Fight!

There is a real threat of food riots around the world unless research into increasing crop yields is stepped up, a leading UK scientist said.
Professor Douglas Kell, chief executive of the Biotechnology and Biological Sciences Research Council told the BBC Radio 4 Today programme: "We have seen already in Indonesia and Mexico riots because of food shortages and what is undeniable is that the amount of food we are going to need to produce to deal with the world's population increases is an extra 50 per cent by 2030 and a doubling by 2050.
"We are going to have to do it on the same amount of land, because there isn't any more land, so we are going to have to increase agricultural yields.
"We are going to have to do that without increasing the amount of oil-based fertilisers we put in because oil is a finite resource and of course produces greenhouse gases.
"And we are going to have to use no more water because water is a resource in short supply as well."
He added: "Scientific research takes a long time to turn into applied fruits that are going to be of benefit to humanity and that is why we need to start the ball rolling now."
