Abstract: Modern agriculture’s intensive land use quashes natural biodiversity and ecosystems. Meanwhile the population will balloon to between eight billion and 10 billion in the coming decades, requiring that more acres be cultivated. Replacing single-season crops with perennials would create large root systems capable of preserving the soil and would allow cultivation in areas currently considered marginal. The challenge is monumental, but if plant scientists succeed, the achievement would rival humanity’s original domestication of food crops over the past 10 millennia—and be just as revolutionary.
