Considering tradeoffs in "local" food policies: examples from school feeding programmes.

City, national, and multinational governments are increasingly leveraging nutrition programme spending, specifically pursuing policies that require or incentive "local" procurement, to meet a myriad of goals.

This perspective article provides some examples of those tradeoffs from the peer-reviewed literature, which, we argue, are useful to consider in setting school feeding programme policies to achieve sustainability goals.
