Africa's 600 million hectares of uncultivated land -- more than half the global total -- adds up to a recipe for a better food future. Agricultural innovation, education, and the resulting empowerment of women and girls promises to make the coming population boom a turning point toward truly sustainable development.

A new scientific report concludes that climate change is already costing the world $1.2 trillion a year. It's also killing at least 400,000 people every year.
