Here is my take on the Zambian grain. The Zambian government doesn’t have the infrastructure to distribute food to its neediest communities, but the WFP does have a distribution method. So the Zambian government buys up a bunch of grain from local farmers, which is good for the local farmers. The Zambian government then donates the grain it just bough to a non-governmental organization, (WFP) that distributes the goods to the communities in Zambia that need it.
