Cleaning out the old bookmarks folder so I wanted to do a quick update post on Africa’s great green wall. Green infrastructure so big, it becomes green geoengineering.
Two weeks ago Senegal put shovels in the ground, kilometer 1 of a 7,775 km long journey east. The green belt will be 15 km wide, hopefully slowing the powerful Sahara. No idea how long this will take to complete, but China is trying something about two thirds as long to fight back the Gobi desert and that should be done by 2050. Quite stunningly the Chinese government estimates it could take 300 years to reclaim the lost land!
