At first it sounds like backwards thinking: revitalize a downtown area by adding miniature plots of farmland on city blocks.

It’s a calm, clear day on West Sacramento’s South River Road, a meandering two-lane route that runs atop a levee buffering houses and farmland from the placid Sacramento River.
