What would it take for you to stop worrying about rot and simply accept it without trying to "work against" it? Basically, what would it take to remove your desire to micro-manage?

I'm not actually asking you to make D'Hara a net exporter, that would make things quite boring. But as long as we require a resource, it's rather normal that we'll do everything we can to minimize waste. Food costs gold, after all, and rotting food is wasted gold.
