African agriculture is at a turning point, and a long-awaited “green revolution” may be within reach. Many of the continent’s governments are adopting market-friendly policies and committing more resources to the sector. Traditional big-donor countries are increasing their expenditures on agriculture, while China and Brazil are also beginning to contribute to the effort. African’s agriculture’s private-sector investment is rising rapidly (see sidebar “Sizing Africa’s agricultural opportunity”). High, volatile food prices underline the importance of such development efforts and create not only pressure but also political space for policy makers to act.
