The July issue of National Geographic magazine features “the biggest story in global agriculture: the unlikely quest to turn sub-Saharan Africa, historically one of the hungriest places on the planet, into a major new breadbasket for the world.” Author Joel K. Bourne Jr. documents the land rush set off by skyrocketing prices for corn, soybeans wheat and rice, with giant agribusinesses eager to lease or buy acreage in places where land is cheap and governments are willing to make deals.

The “green revolution” — the fertilizers, irrigation and high-yield seeds that doubled global grain production between 1960 and 2000 — never really took hold in Africa, Bourne writes.

But that seems to be changing dramatically. Bourne describes a Chinese corporation that is building a 50,000-acre farm in the Limpopo River delta, as well as a New York conference for agricultural investors that drew 800 financial leaders looking for places to invest nearly $3 trillion for pension funds, life insurance companies, hedge funds and so on.

The good news is that growing investment in sub-Saharan countries could provide more food — as well as jobs and infrastructure that could result a higher standard of living — for Africans.
