The Royal Society says that by the middle of the century the global population may reach 9 billion. And feeding those extra mouths is a major challenge for the planet, compounded by the spectre of global warming.

Professor David Baulcombe of Cambridge University, who led the research, says a billion people are already malnourished. Professor Baulcombe says the money the government should plough into crop science is needed immediately. If we wait ten years, he says, it may be too late. The genetic manipulation he refers to could produce crop strains resistant to disease, drought and salinity.

But the issue of genetically modified crops is still something of a hot potato, despite the technology being already used by millions of farmers. Environmental groups say the usefulness of GM crops has not been proven, and the threat they pose by letting altered genes spread into other plants is significant.
