Organic farming has a key role to play (#journal)

Organic agriculture in the twenty-first century

The authors examine the performance of organic farming in light of four key sustainability metrics: productivity, environmental impact, economic viability and social wellbeing. Organic farming systems produce lower yields but are more profitable and environmentally friendly, and deliver equally nutritious foods that contain less (or no) pesticide residues. Moreover, organic agricultural systems deliver greater ecosystem services and social benefits. No single approach will safely feed the planet; a blend of organic and other innovative farming systems is needed. Significant barriers exist to adopting these systems, however, and policy instruments will be required to facilitate their development.
