Revolutionary Rice — The Long Now Foundation

Feeding the world (and saving nature) in this populous century, Jane Langdale began, depends entirely on agricultural efficiency — the ability to turn a given amount of land and sunlight into ever more food. And that depends on three forms of efficiency in each crop plant: 1) interception efficiency (collecting sunlight); 2) conversion efficiency (turning sunlight into sugars and starch); and 3) partitioning efficiency (maximizing the edible part).
