Giving Compass' Take:
- Researchers believe that climate change will impact crop growth and yields, significantly reducing the number of food farmers can produce over the years.
- How can donors help advocate for climate policies that will consider future food security?
- Read more about the connection between climate change and world hunger.

Researchers have once again warned that climate change is likely to mean a hungrier world with less food on the table: by 2050, global crop yield could have fallen by 10 percent. And by the century’s end − and with a much larger burden of human population − farmers might be producing 25 percent less than they do now.
The calculations come just a few weeks after a separate team of scientists predicted that uncontrolled global heating driven by continued profligate use of fossil fuels might change the global climate in ways that could cut harvests by as much as a third.
Food is not separable from climate change: modern agriculture and the global appetite for animal products is both a major contributor to ever-greater greenhouse gas emissions and, in very different ways, a potential answer to some of those challenges.
Demand for food for ever-greater numbers of increasingly wealthier people has driven the destruction of forests, savannahs and wetlands that nurse life’s variety, underwrite the planet’s economy, and buffer nations against climate change.
But researchers have also found, again and again, that with a different mindset and a shift of global appetite, it might be possible to feed 10 billion people and preserve the planet’s biodiversity.
That is based on an assumption that climate change fuelled by greenhouse gas emissions doesn’t change the nature of farming. And, increasingly, researchers believe that it will.
