Among the many signals that Trump sent in his speech to the United Nations, one was especially clear: former chief strategist Steve Bannon’s White House departure has not muted the president’s “America First” foreign policy instincts.
Current efforts to increase food production in the developing world—especially in Africa, largely bypassed by the green revolution—may only accelerate the pace at which livestock breeds and crop species disappear in the years to come. In pockets of Africa where high-yield seeds and breeds have been introduced, the results have been mixed at best. Countries like Zimbabwe, Zambia, and Malawi ended up sacrificing much of their crop diversity to the monocropping of imported, high-yield varieties subsidized by government programs and provided by aid organizations. Small farmers and pastoralists have gone deep into debt to pay for the "inputs"—the fertilizers, pesticides, high-protein feeds, and medication—required to grow these new plants and livestock in different climate conditions. They are like addicts, hooked on a habit they can ill afford in either economic and ecological terms.
Until 2017, worldwide deaths from famine had been falling dramatically. The world Peace Foundation reported that from the 1870s to the 1970s, great famines killed an average of 928,000 people a year.  Since 1980, annual deaths had dropped to an average of 75,000, less than 10% of what they had been until the 1970s. That reduction was achieved despite the approximately 150,000 lives lost in the 2011 Somalia famine . Yet in 2017, the UN officially declared famine had returned to Africa, with about 20 million people at risk at death from starvation in Nigeria, in South Sudan , in Yemen , and in Somalia .
