Bill GatesExerpt:
Africa will be able to feed itself. Today, the continent has to rely on imports and food aid to feed its people, even though
seven out of 10 people in sub-Saharan Africa are farmers. Part of the problem is that African farmers get just a fraction of the yields that American farmers get.
In the next 15 years, however, innovations in farming will erase these brutal ironies. With better fertilizer and hardier crops, African farmers will be able to grow a greater variety of food and sell their surpluses to supplement their family's diet with vegetables, eggs, milk, and meat.
Even as climate change makes farmers' job more difficult, we can get them enough innovation and information to increase productivity by 50% for the continent overall. Countries like Ghana are also building better roads and adopting policies that make it easier to move food to the places where it's most needed. In 15 years, Africa will still import food when it makes sense to do so, but it will also export much more, eventually achieving a net positive trade balance.
