Should we turn deserts into carbon-sucking tree plantations?


Grist

To fight climate change, some scientists think we should vegetate the hell out of deserts. The latest such idea calls for large plantations of a hardy species of Central American tree to be planted in near-coastal desert areas and irrigated with desalinated water.

While forests soak up carbon dioxide, deserts do comparatively little to help with climate change. So should these seas of sand be planted and watered out of existence in a bid to reduce CO2 levels?

Some say yes. The approach would be like geoengineering, but rooted in a more natural system. Scientists call it bioengineering or carbon farming.

The idea of replacing deserts with forests to help the climate is not brand new. A few years ago, for example, scientists proposed planting eucalyptus trees through the Saharan and Australian deserts to help absorb carbon dioxide.
