“…This work provides semi‐theoretical relationships (Figure 4) to link groundwater use information at aquifer‐system scale with compaction and storage loss, potentially enabling predictions of subsidence rates and volumes for different groundwater management scenarios. While these relationships may need further tailoring at local scale, they provide a first high‐level assessment of the potential additional compaction resulting from increased pressure on groundwater resources (or also, reduced pressure induced by managed recharge; Cruz‐Ayala & Megdal, 2020). Given population growth and renewable freshwater availability drop expected in 2030 (CONAGUA, 2022b), this is key information to feed into decision making and water management strategies.…”

Aquifers host 30% of global freshwaters (Shiklomanov, 1993), and play an important role in addressing water needs worldwide, especially in countries with extensive arid regions (United Nations, 2022). In Mexico, 39.5% of the consumed water is supplied through ∼35,300 hm 3 /year groundwater, extracted from ∼300,000 wells and used for agriculture (71%), public supply (21%), industry and electric energy (excluding hydroelectric) (8%) (CONAGUA, 2022b). Although Mexico is not considered "water-poor", large discrepancies in recharge and consumption rates and patterns exist: only 20% of the total annual rainfall occurs where 76% population lives and 90% irrigated lands are maintained (Hernandez, 2003). In 2020, the National Waters Commission (CONAGUA) identified 157 overexploited aquifers near densely populated cities and large farmlands, and 48 threatened by salinization and/or marine intrusion (CONAGUA, 2022b). Land subsidence resulting from groundwater overexploitation has also been documented in major cities of Central Mexico (Cabral-Cano et al., 2008;Carreon-Freyre et al., 2011). Topographic lowering, tilting and deformation, apparent uplifting of deeply founded structures, surface cracking and faulting are very common impacts that aquifer-system compaction causes on Mexican urban landscapes (Carreón Freyre, 2010;Figueroa-Miranda et al., 2018), and in many other countries (Galloway &

“…Understanding the food system in Mexico is complex, since the bases for food production nowadays (i.e., natural resources) are every time more threatened and scarce, especially water [121,122]. Although the sixth goal of the SDG addressed the urgency to provide availability and the sustainable management of water and sanitation for all [94], and the legal management of water is specified in articles 4, 27, and 115 of the Constitution, which lay the foundations for the legislation of water [123,124], the current data shows that the water crisis is on the rise.…”

The Mexican food system has suffered deep transformations due to multiple technological advances and political and free trade agreements, transiting from a food system for self-consumption to a system based on exports and imports that has resulted in excessive agricultural activity intensification, leading to environmental deterioration. Our species’ survival will depend on our capacity to manage systems, considering all ecosystems, especially the climate and food systems. International organizations insist that sustainable food systems could be a useful strategy to address malnutrition and hunger while respecting the environment. However, the food system in Mexico needs to be connected to the environmental, social, health, and food security dimensions. Sustainability in Mexico synthesizes the contradictions of agriculture and the Mexican diet, not only in its economic and productive dimensions but also in the social and environmental ones. Public policies in all sectors of the country must be interconnected and organized to guarantee the sustainability of a system that benefits the environment and population health while respecting the related economic and social elements. This review aims to offer a comprehensive understanding of the Mexican food system’s history and current situation and analyze proposals for its sustainability.

“…Additionally, reclaimed water lacks definition in the law and how it can allocated, providing uncertainty in terms water rights to begin with. If a water agency recharges treated waste water, they lose their rights to the recharged water, providing a disincentive to recharge treated waste water (Cruz‐Ayala and Megdal 2020).…”

The Mexico City Metropolitan Area (MCMA) is a significant and important urban center in North America, covering an area of approximately 9500 km2 with a population of almost 23 million, yet the water supply remains unsustainable. The total water demand in the MCMA is 84 m3/s and is provided by groundwater (63% or 53 m3/s), imported water (27% or 23 m3/s) and recycled water (10% or 8 m3/s). The natural recharge of the MCMA aquifer is approximately 23 m3/s, indicating an overexploitation of groundwater resources of approximately 25 m3/s (800 Mm3 annually), a reasonable future goal for recharge in the MCMA. Hydrologic analysis indicates two main opportunities currently to increase water supply in the MCMA: indirect water reuse with recycled water and managed aquifer recharge (MAR) with storm water. An inventory of MAR project case studies in the MCMA summarizes methods for recharge, water sources, geographical distribution, and the main results obtained in each project for the last 80 years. The inventory consists of 21 MCMA area MAR case studies including (1) conceptual, (2) design level, and (3) pilot‐ to full‐scale facilities, only some of which have operated for relatively short periods of time, with one remaining MAR project currently operational. The review found that beyond the technical and economic issues that MAR project design normally address, the existing regulatory framework and the continuous change in water district chairs in charge of the operation and supply of water are significant barriers to increasing MAR in the MCMA.
