Water Scarcity and Conflict in Mexico’s Agricultural Export Zones

In San Andrés Tziróndaro, a Purépecha community on the shores of Lake Pátzcuaro in Michoacán, water has become a site of conflict. Water is diverted from the lake to irrigate nearby avocado plantations, while recent drought conditions have reduced lake levels to historic lows, collapsing fish populations and disrupting local livelihoods (The Guardian, 2026). At the same time, surrounding forests have been cleared for agricultural expansion, and residents attempting to defend their land and water face threats, violence, and displacement (The Guardian, 2026). What is unfolding in San Andrés Tziróndaro reflects a broader national water crisis in Mexico, driven by climate change, agricultural expansion, and unequal resource distribution. More than half of Mexico’s major reservoirs operate below 50% capacity, and 115 of 650 aquifers are overexploited, while per capita water availability has declined by nearly 30% over the past three decades, leaving over two-thirds of the population under water stress (Pacheco-Treviño & Manzano-Camarillo, 2024). These pressures are especially pronounced in rural agricultural regions, where export-driven farming and groundwater overextraction have reduced access to reliable water sources, forcing communities to rely on increasingly scarce or contaminated wells, ponds, and rainwater (Pacheco-Treviño & Manzano-Camarillo, 2024). At the same time, water governance systems often prioritize agricultural and industrial use, further exacerbating inequities in access and contributing to growing water scarcity and conflict across the country (Orozco-Ramírez, Astier, & Barrasa, 2017). These dynamics are particularly pronounced in Michoacán, one of the most important agricultural regions in Mexico and a central hub of global avocado production. Mexico produces approximately 45% of the world’s avocados, with roughly 92% originating from Michoacán alone (Rodríguez-García et al., 2026). This concentration is enabled by highly favorable environmental conditions, including optimal elevation, suitable temperature ranges, sufficient precipitation, and fertile volcanic soils, which make the region uniquely suited for large-scale agricultural production (Rodríguez-García et al., 2026). However, these same conditions have also facilitated the rapid expansion of export-oriented farming, intensifying pressure on local water systems and contributing to growing environmental stress and conflict. This paper examines how climate stress, agricultural intensification, and groundwater depletion interact to intensify water scarcity and conflict in Michoacán. By integrating climate data, land-use change, and hydrological indicators, this study analyzes how shifting rainfall patterns and export-driven agricultural expansion are reshaping water availability in one of Mexico’s most hydrologically and politically contested regions. In doing so, it seeks to identify the environmental and social conditions under which water scarcity evolves into conflict, with implications for water governance, rural livelihoods, and environmental justice.
