Thank you for demonstrating my point. Though this article, quoting the UN, talks about insect farming AS ONE OF THE OPTIONS, they want to promote this as an alternative for more people around the world who are suffering from malnutrition, the article says. Here is the how this would play out:
People that are malnourished are often so because of lack of money to purchase food. If people start eating more insects, the poor (and malnourished) will try to get the bugs themselves or farm them (they won't have the money to purchase them). The result will be a more dangerous diet.
While many will look at this article in the context of their own living situation, the common failure of the UN is understanding how this will translate in the poor around the world.
Perma-culture, since you doubt it, too, can be easily looked up. I was in Zimbabwe last summer in areas where the UN had already been working with farmers. They were all talking about the UN reps and their plan to use perma culture as a way to improve yield. Not one of them was even going to try it, nor could they, unless they wanted their family to starve in the first three years.
My point is to step outside of our worldview when proposing ways to help and understand what will really happen when we head down a road. This is not a good idea and will be shot down by people that have real practical experience and knowledge in 3rd world conditions.
