Peter Alexander

Peter's work focuses on the social, economic and ecological interactions within the global food and land use systems, typically applying data and computationally intensive techniques. The work considers interactions between climate change adaptation and mitigation, as well as how the globalisation of the food system creates teleconnections between actions in one location having consequences in others. The role of international trade in reducing or exacerbating vulnerabilities to shocks, including geopolitical shocks, is a particular interest. How land use and food system changes interact with dietary choices and human health, e.g. patterns of food consumption influencing environmental outcomes and environmental changes impacting nutrition and health, are also considered in his research. To better understand these interconnections, in collaboration with others, he led the development of the international Land System Modular Model (http://www.landsymm.earth) collaboration. He is a Lead Author for the 2022 IPCC (WGII) report assessing the Impacts, Adaptation and Vulnerability to climate change, and is a Coordinating Lead Author on UNEP’s 7th Global Environmental Outlook (GEO-7).
