One thing that is not utilized very much in Canada--this ties into some of what I brought up earlier, about existing programs that might support agricultural production--is the direct provision of food aid. That is not universally popular because of concerns that it might carry stigma for recipients. However, if you're thinking of interventions on a community-wide basis, where there might be a role or an ability for a government or a third party to purchase food items to be provided to remote communities, that could be done in a way that would also promote the producers' interests and perhaps could replace other programs that currently work by affecting food prices. That might be a win-win situation.
Again, on a community level, perhaps it would not involve the same sort of stigma carried by the idea of buying government cheese, or by the idea of food stamps in other countries.
