Last Wednesday (December 11, 2013), the final installation of a 3-volume set studying climate change impacts on agriculture was released during ASARECA’s Second General Assembly held in Bujumbura, Burundi. The book, published by IFPRI, was edited by Michael Waithaka, Timothy S. Thomas, Miriam Kyotalimye, and Gerald Nelson.
The purpose of the book is to help African policymakers, researchers, NGOs, and donors to better plan and prepare for climate change impacts, national-level studies were recently undertaken that provide spatially-refined analysis of impacts of climate on key crops, along with additional analysis that consider global trends and other factors that are changing with the climate, including GDP, population, and agricultural technology development and use. Judging by the enthusiastic reception (200 copies of the book were handed out in 90 minutes), it is one that meets a great need and addresses a serious gap in knowledge.
In the book, the authors used two approaches to study the impact of climate change on agriculture. The first was to apply the DSSAT crop modeling software to climate model data, to see how crop yields of major crops would be impacted by climate change, not accounting for technological change or adaptation. The second was to use a large global partial equilibrium model focusing on food and agriculture, IMPACT, to take into account population and GDP growth on demand, as well as to consider the supply response, as impacted by climate change and also technological change.
Readers interested in downloading one of the chapters or the entire book can find it on the IFPRI website.
