As experts gather in The Hague this week for a Global Conference on Agriculture, Food Security and Climate Change, a major issue concerning Africa is the importance of the continent’s soil.

Experts differ on the best ways to turn often parched and depleted land into fertile ground. But there is general agreement that it is an issue that needs to be addressed.

The director of the Tropical Agriculture and Rural Environment program at Columbia University, Pedro Sanchez,
