A bitter cup: climate change profile of global production of Arabica and Robusta coffee Christian Bunn* christian.bunn@hu-berlin.de Source: Climatic Change - An Interdisciplinary, International Journal Devoted to the Description, Causes and Implications of Climatic Change Via SpringerLink Published online: December 13, 2014 Abstract Coffee has proven to be highly sensitive to climate change. Because coffee plantations have a lifespan of about thirty years, the likely effects of future climates are already a concern. Forward-looking research on adaptation is therefore in high demand across the entire supply chain. In this paper we seek to project current and future climate suitability for coffee production ( Coffea arabica and Coffea canephora ) on a global scale. We used machine learning algorithms to derive functions of climatic suitability from a database of geo-referenced production locations. Use of several parameter combinat...
