Review of water scarcity assessments: Highlights of Mexico's water situation

Abstract

AbstractThis article examines the situation of water scarcity and security in Mexico, with a focus on the drinking water supply issue in rural communities and the challenges posed by assessment methodologies. We conducted a comprehensive literature review to update the available information on the water crisis in Mexico and its impact on rural communities in the country, as well as the methodologies employed to assess water security and the methodological challenges associated with them. Among the most noteworthy findings is the persistent challenge in evaluating water scarcity and its implications for communities, due to the lack of consensus on the most precise methodology. Nevertheless, current methodological approaches suggest the integration of physical models with pertinent social, economic, and political data. The literature broadly agrees on the severity of the water scarcity crisis and the clear link between rural poverty and inadequate access to drinking water. Water scarcity is both a contributing factor to and a consequence of poverty, stemming from a complex interplay of socioeconomic pressures, inadequate institutional responses, and deficient water management. The paper concludes that water scarcity involves intricate interactions among various factors, encompassing physical water scarcity, pollution, and the impacts of climate change on the water cycle, and most critically, the complexities inherent in water management and regulatory frameworks. Therefore, the integration of well‐informed policies, effective management practices, and collaborative efforts is crucial for ensuring a prosperous and sustainable future. Effective water management can effectively mitigate the challenges of water scarcity and alleviate poverty.This article is categorized under: Engineering Water > Water, Health, and Sanitation Human Water > Rights to Water Science of Water > Water and Environmental Change
