Grow whatever grows best in your area. Grow some of the food that doesn't grow best, but still is productive. Eat locally. Eat seasonally. Can/preserve food when you have an excess at harvest time, use cold storage liberally. Trade harvests with your neighbors to get more variety. Do that, and the issues raised in your citations are pretty much fixed.

(And while I didn't have time to read the longer article, even its abstract at top said that proper vegetable storage can resolve the issues.)

There are also more benefits to growing your own food than decreasing a carbon footprint. We put a ton of work into our family farm, to help our kids grow up to be stronger people with a better understanding of where food and other household products come from. It is hard work, and doing it purely on solar power and manual labor makes it even harder. Buying food at a grocery store would be WAY easier, but doing things the easy way isn't our goal in life.

Carbon footprints don't even make the list when we talk about the reasons why we do this.
