Sustainable Agriculture
Farming practices maintaining productivity while preserving soil health, biodiversity, and water quality for long-term food security.
Real World
The Rodale Institute's 30-year trial in Pennsylvania showed that organic, rotation-based farming matched conventional yields while reducing nitrogen runoff by up to 50%, demonstrating sustainable productivity.
Exam Focus
Define sustainability clearly at the start — environmental, economic, and social dimensions — as mark schemes often award this explicit definition.
