Bloomberg's Jennifer Zabasajja speaks to UN Deputy Secretary-General Amina J. Mohammed on the growing strain on Africa's food systems and the impact on food security. Plus, we head to South Africa’s Karoo, where a harsh desert landscape is being transformed into a potential pistachio hub. (Source: Bloomberg)
