You can’t boil it down too much — it’s worth a whole book — but here are a few critical factors:

Farming:  In the corporate world, they’d call it “rebranding.” We need to see farming as the creative, important, healthy, soul-affirming, community-rich work it is (or can be), and start paying better for it — instead of dismissing it, as many urban people do, as boring, hard, risky, and ill-paid. We need to make farming sexy enough to attract good minds.

Soil: We need to start thinking about it as a rich natural resource to be conserved, not as something to mine.

Water: It’s essential, limited, easy to waste, and easy to ruin with pollution. We’re going to run short of it — we already are in a lot of places — but there’s plenty if we use it wisely.

Fertilizer: Gotta throw some dollars here. We’re using fertilizers developed 50 years ago, and they’re not what we need now. Let’s support research to develop next-generation fertilizers that are cheaper to produce and less polluting.

Markets: We need to find more direct ways to link farmers with consumers, eliminating the high costs of middlemen.

These are just a few bullet points. There’s much more to think about — what have I missed?
