Wes Jackson believes that shifting from fragile annual monocultures to more hearty perennial grains grown in a mixture of plants (polycultures) is the key to a truly sustainable agriculture. Instead of a brittle industrial agriculture dependent on fossil fuels, Jackson’s research team is working to build a resilient agriculture modeled on natural ecosystems.
With the health of our soils and our own bodies at stake, Jackson says, we can’t afford to assume old approaches can cope with coming crises. Because humans like to resolve ambiguity, we reward researchers who appear to do that within existing systems — such research may be right but irrelevant, if the real problem is at the level of the whole system. Solving individual problems within a system that can’t be sustained actually creates problems.
