I think we need to consider a build up of an emergency employment capacity in the world. The idea is to make use of both money and the working capacity of the refugees. For a large refugee camp you probably need a distribution of companies, shops, services and factories. In short you need a lot of employment possibilities. Even if some companies won’t generate a profit. Any income generated under these circumstances is better than nothing. So the idea is to help companies that can turn a working capacity into money for the refugees.
Another idea inspired by Africa and Turkey is to take advantage of drought resistant potatoes that possibly can be grown in bags. I thought maybe these could generate a little income for refugees in those large camps.
