The Potash Trilemma: Geopolitics, Market Dynamics, and Global Food Security

ABSTRACT Potash is essential for plant growth and global food production. However, its distribution and access are uneven, creating significant economic and geopolitical challenges. We here explore the complexities of the global potash market, focusing on the impacts of mine location, ownership, and the oligopolistic structure of the market on food security. Through historical analysis and the development of potash vulnerability indexes, the research highlights the risks associated with concentrated production and the implications for countries with varying levels of economic power. The findings underscore the potential for market manipulation and the exacerbation of food insecurity, particularly in lower‐income nations. As potash resources become scarcer, strategic management by producers may lead to higher prices, further widening global inequalities. This study suggests a reevaluation of the current situation to address these emerging threats to global food security.
