This short introductory essay argues that agriculture can be made far more sustainable by transitioning to perennials.Conversion of annual fields into perennial fields offers many biodiversity-friendly
benefits; reduced soil erosion, reduced chemical run-off, reduced water use and reduced fossil fuel input.The Land Institute, a United States non-profit group devoted to sustainable agriculture,
offers a 50 year farm plan that aims to convert U.S. farmlands to 70 percent perennial crops from their current state of
25 percent perennials within 50 years. The Land Institute’s plan can be adapted to any developed government with centralized
research and agriculture support.
