The document discusses sustainable intensification approaches to transform key African farming systems. It notes that over 1 billion people are hungry in Africa where most agriculture is rainfed with poor soils. The Green Revolution improved yields but failed to address social and environmental issues. The Africa RISING program is researching options for smallholders in three regions that meet multiple needs through approaches like push-pull pest management using desmodium and napier grass, evergreen agriculture with nitrogen-fixing trees, and doubled-up maize-legume systems. These sustainable intensification methods can increase yields and reduce risk while protecting soils and water.
