Feeding Africa: Australian knowledge helps meet a continent’s climate change challenges

Increasing population and climate change will make it even harder for the world to feed itself. Gates Foundation

The world’s population has just hit seven billion and nearly one billion people do not get enough to eat. Agricultural land is being degraded at the rate of 12 million hectares a year and the world faces a huge challenge in feeding this growing population - a challenge that will only be exacerbated by climate change.

The world will need to produce 60-80% more food by 2050 to adequately feed nine billion people, many of whom will require a higher-calorie, higher-protein diet than can be provided today. This challenge is akin to almost doubling food production and reducing the environmental foot print by using less water and other scarce resources.

Why isn’t the green revolution rolling on?

History has shown that innovation in agricultural production can meet big challenges. Between 1961 and 2008, the world’s population increased by a total of 117% and crop production rose by 179%.
