No more farmers?

There is every chance we will run out of farmers before we know whether we can feed the people of the world.

It’s a frightening proposition but just look at the evidence.

In 1968, Paul Ehrlich in his book ‘Population Bomb’ made the prediction the world faced massive starvation due to overpopulation. He wrote:

The battle to feed all of humanity is over. In the 1970s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now. At this late date nothing can prevent a substantial increase in the world death rate.

Then along came Dr Norman Borlaug, ‘the father of the Green Revolution’, and his team of plant breeders and the world was saved from starvation. In 1970, Borlaug became a Nobel Laureate.

The ‘Green Revolution saved India from certain disaster.

Between 1950 and 2004 world wheat yields rose from an average of 750kg/ha to 2750kg/ha (FAO), due to the worldwide adoption of high yielding, high input short straw wheat varieties, developed by Borlaug and his teams. Similar improvements were achieved in the yields of maize and rice.

This revolution in plant breeding, combined with new chemicals to control pests and diseases averted the global starvation tragedy predicted by Ehrlich.

In the last forty years the population of the world has doubled and, by and large they have all been fed.

The millions, who have died of starvation over that period, didn’t die because there wasn’t any food for them; they died because we spent our money fighting wars rather than getting food to those who needed it. Continue reading “No more farmers?”
