Famine, World Starving Can be Avoided by Doubling Food Output: Experts

Leading scientists have said that global food production needs to be increased by between 50 and 100 per cent if widespread famine and world starving is to be avoided in the coming decades as the human population expands rapidly.

According to a report in The Independent, the experts, drawn from the Royal Society, Britain's national academy of scientists, said that a second "green revolution" is needed in agriculture to feed the extra 3 billion people who will be added to the existing population of 6 billion by 2050.

World Will Need 70 Percent More Food in 2050: FAO
World food production must increase by 70 percent by 2050, to nourish a human population then likely to be 9.

They 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 in human numbers.

They cite the original green revolution of the 1960s when new crop varieties, greater use of agro-chemicals, and a change in farming practices led to a dramatic increase in food production: it leapt from 1.84 billion tonnes in 1961 to 4.38 billion tonnes in 2007.

But, scientists accept that this increase came at great environmental cost, and the Royal Society report warns that a second green revolution has to be based on a sustainable increase in global food production without a significant expansion in the area of land turned over to farming.

Artificial Chromosome Could Help Boost Food Production
An artificial chromosome for corn plants has been developed by Chicago researchers. This may speed efforts to produce fuels and medicines from plants as well as boosting crop nutrition and yield.

"There is insufficient water to support an increase in the cultivated areas, and the environmental consequences of increasing cultivated areas are undesirable. Additional production will have to take place without further damage to the environment," the Royal Society report said.

The area of land available to sustain each human being is "dangerously declining" because of soil degradation, according to the report.

The World Faces a New Crisis: The Food Crisis
A new predicament seems to be threatening the world. Strategists have said that a global food catastrophe will be more crippling than anything the world has ever seen.

According to Professor Sir David Baulcombe of Cambridge University, who led the study, the Government must be prepared to pay 2 billion pounds over a period of 10 years to fund research into ways of boosting food production around the world.

"We need to take action now to stave off food shortages. If we wait even five to 10 years, it may be too late," he said.

Climate Change Threatening Rice Production, Claims Scientists
In a new research, scientists have determined that climate change is threatening rice production.

"There's a very clear need for policy action and publicly-funded science to make sure this happens," he added.

The Royal Society report says that a range of measures, from new ways of managing crops - such as changes to the way they are irrigated - to the introduction of GM varieties that are drought-resistant or salt-tolerant, will all have to be called upon to boost food production.
