Global food production ‘must increase’

Global food production needs to be increased by between 50 and 100% if widespread famine is to be avoided in the coming decades, leading scientists said.
A second "green revolution" is needed in agriculture to feed the extra 3 billion people who will be added to the population by 2050.
The experts, drawn from Britain's national academy of scientists, believe that a variety of short-term and longer-term measures will have to be adopted urgently if agricultural production is to meet the demands made by the growth.
They cite the original green revolution of the 1960s when new crop varieties and a change in farming practices led to an increase in food production.
