摘要：Land grabbing is a global phenomenon that has radically increased since 2005. Global andnational estimates are highly uncertain due to the rapid pace of acquisition and lack oftransparency. Here we demonstrate that through the use of the Geo-Wiki crowdsourcingtool and volunteers, we can estimate areas of settlement and cultivation that are part oflarge-scale land transactions for known areas where land acquisitions have taken place aswell as for Ethiopia as a whole.
