We need to "Perennialize" agriculture. Perennial agriculture, including perennial grains, oil seeds and legumes as well as forages and trees can take sustainable intensification to the next level and achieve productivity goals as well as social and ecosystem service benefits. It has been only in the past few years that the benefits of developing perennial grain-based cropping systems and the need to do so have become widely acknowledged. This has drawn the attention of major scientific societies, leading journals and governmental agencies. Much of that attention has been focused on the ecological benefits that perennial plants can confer on landscapes: erosion prevention, efficient capture and use of water and nutrients, protection of water resources, carbon sequestration and maintenance of thriving soil ecosystems. © FAO: http://www.fao.org
