World one poor harvest away from chaos

What is needed now is a worldwide effort to raise water productivity, similar to the one launched by the international community a half century ago to raise cropland productivity. This earlier effort tripled the world grain yield per acre between 1950 and 2010.

On the climate front, the goal of cutting carbon emissions 80 percent by 2050—the widely accepted goal by governments—is not sufficient. The challenge now is to cut carbon emissions 80 percent by 2020 with a World War II-type mobilization to raise energy efficiency and to shift from fossil fuels to wind, solar, and geothermal energy.

On the demand side, we need to accelerate the shift to smaller families. There are 215 million women in the world who want to plan their families, but who lack access to family planning services. They and their families represent over a billion of the world’s poorest people. While filling the family planning gap, we need to simultaneously launch an all-out effort to eradicate poverty. Once under way, these two trends reinforce each other.

And in an increasingly hungry world, converting grain into fuel for cars is not the way to go. It is time to remove subsidies for converting grain and other crops into automotive fuel. If President Sarkozy can get the G-20 to focus on the causes of rising food prices, and not just the symptoms, then food prices can be stabilized at a more comfortable level.
