As 2050 drawers nearer, global food production faces growing demand for food, challenges from climate change and globalization. As ensuring food security for a growing global population will require innovative and sustainable solutions, research in this field endeavors to understand the landscape of food security in the coming decades. As such, global food security and computable general equilibrium modelling have partnered to help assess how these challenges will affect our ability to produce food. However, knowledge and research gaps remain. Thus, this paper innovatively highlights that food security analysis using computable general equilibrium modelling can be enhanced by filling one part of the mineral resource gap by including the critical element phosphorus. This paper provides a detailed literature review on current approaches in phosphorus modeling and their contributions to economic modeling and how current knowledge gaps can be bridged by including phosphorus into food security analyses using computable general equilibrium modeling.
