“…We recognize limitations to this proposal, mostly related to enabling conditions, including the availability of suitable habitat (water), as Mexico deals with severe problems in water availability and pollution, as well as increased drought and flooding. The most overexploited aquifers are situated near the biggest cities, or at the north, where most arid areas occur (Ortiz-Partida et al, 2020) (Otazo-Sánchez andNavarro-Frómeta 2020), and this condition is expected to worsen due to climate change, which will increase the pressure on the already highly threatened freshwater ecosystems in Mexican arid lands (Contreras-MacBeath et al, 2014). Another limitation that relates to the reintroduction component of this proposal, is the availability of suitable species founder stocks, with adequate genetic lineages, to avoid hybridization, or other detrimental genetic consequences.…”

Freshwater ecosystems are considered amongst the most imperiled on earth, since rivers, lakes, wetlands, and other surface waters receive most of the impacts from unsustainable human activities. This has had measurable impacts on freshwater species, and more specifically on freshwater fishes, as data from the Red List show that 23.5% of the 11,937 freshwater fish species evaluated so far, are classified as threatened. Mexico is not exempt from this situation, as a recent report demonstrates that 39.9% of Mexican freshwater fishes are threatened, and there are 21 lost species (extinct + extinct in the wild), the highest number for any country or region of the world. Here we develop a Theory of Change (ToC) to guide management interventions when seeking to prevent further freshwater fish extinctions in Mexico and reversing the current extinction crisis. We describe four thematic areas of intervention: (1) restoration and reintroduction aimed at eight extinct in the wild and four regionally extinct species, (2) conservation management prioritizing 39 critically endangered species, distinguishing between those inhabiting protected areas, water parks, and those with no management nor protection, (3) explorations to find eight possibly extinct species, and (4) communication and outreach to gain support for conservation interventions. The framework has been developed as a tool for conservation advocates and policymakers to implement and monitor change that prevents extinctions, but also to seek and attract funding. It is also meant to guide different levels of government in setting priorities for conservation interventions.

“…First, enhanced access to supplemental irrigation could help close chronic gaps in maize yield, which are largely driven by crop water deficits [50,53]. In turn, enhanced productivity could reduce food insecurity, generate economic development, and reduce poverty in the region [51,65,66]. The potential benefits of southern irrigation expansion have come into greater focus due to two factors.…”

Sustainable water management is a core sustainable development goal (SDG) that also contributes to other SDGs, including food and water security, ecosystem health, and climate adaptation. To achieve these synergies, policies must target efforts to regions that best correspond with development objectives. This study designs a targeting strategy for irrigation expansion in southern Mexico—a region long considered to have strong potential for sustainable irrigation development. We use an integrated farm typology and decision tree approach to identify priority municipalities for irrigation expansion. We use multivariate statistics to examine the relationships among farm characteristics in 933 municipalities, classifying each according to four farm types: lowland, midland, midland-irrigated, and highland. We then partition municipalities into 11 farm-type subgroups, each ranked by priority level for receiving irrigation interventions following Mexico’s National Water Program guidelines. Results identify a ‘highest-priority’ subgroup of 73 municipalities comprised mostly of midland and highland farm types. These types are characterized by low irrigation use, small farmland areas, high vulnerability to climate, high marginalization (poverty), strong representation from indigenous communities, low maize yield, and high rates of subsistence production. Findings provide a crucial first approximation of where irrigation expansion would best address water policy priorities and sustainable development objectives in southern Mexico. This study also provides a useful framework for scaling organizations tasked with targeting development efforts across large spatial scales.
