“…Similarly, the authors of [25] found that for this month, 20.5% of the time series were statistically significantly negative; however, their investigation did not report any magnitude. In the area of influence of Aguascalientes and Presa El Niagara weather stations, in April, a negative trend of precipitation could increase the aridity index when combined with the evaporation increase [34]. This can increase the natural vegetation dormancy and aggravate the problem of low forest productivity [50].…”

“…According to Ruiz-Alvarez et al [33], this state already faces increases of the monthly minimum temperature of between 0.09 and 1.19 • C decade −1 , and of the monthly maximum temperature of between 0.18 and 1.59 • C decade −1 . Additionally, reports exist that this state shows statistically significant increases on monthly evaporation up to 26.90 mm/month/year in March [34]. For this reason, studies that focus on the understanding of precipitation patterns would generate results of great value, mainly in this region where there are overexploited aquifers.…”

The objective of this research was to analyze the temporal patterns of monthly and annual precipitation at 36 weather stations of Aguascalientes, Mexico. The precipitation trend was determined by the Mann–Kendall method and the rate of change with the Theil–Sen estimator. In total, 468 time series were analyzed, 432 out of them were monthly, and 36 were annual. Out of the total monthly precipitation time series, 42 series showed a statistically significant trend (p ≤ 0.05), from which 8/34 showed a statistically significant negative/positive trend. The statistically significant negative trends of monthly precipitation occurred in January, April, October, and December. These trends denoted more significant irrigation water use, higher water extractions from the aquifers in autumn–winter, more significant drought occurrence, low forest productivity, higher wildfire risk, and greater frost risk. The statistically significant positive trends occurred in May, June, July, August, and September; to a certain extent, these would contribute to the hydrology, agriculture, and ecosystem but also could provoke problems due to water excess. In some months, the annual precipitation variability and El Niño-Southern Oscillation (ENSO) were statistically correlated, so it could be established that in Aguascalientes, this phenomenon is one of the causes of the yearly precipitation variation. Out of the total annual precipitation time series, only nine series were statistically significant positive; eight out of them originated by the augments of monthly precipitation. Thirteen weather stations showed statistically significant trends in the total precipitation of the growing season (May, June, July, August, and September); these stations are located in regions of irrigated agriculture. The precipitation decrease in dry months can be mitigated using shorter cycle varieties with lower water consumption, irrigation methods with high efficiency, and repairing irrigation infrastructure. The precipitation increase in humid months can be used to store water and use it during the dry season, and its adverse effects can be palliated with the use of varieties resistant to root diseases and lodging. The results of this work will be beneficial in the management of agriculture, hydrology, and water resources of Aguascalientes and in neighboring arid regions affected by climate change.

“…In Iran, a significant decreasing pan evaporation trend from 1995 to 2015 was found (Shimi et al., 2020), while a 16 mm/a/a increasing trend occurred from 1982 to 2003 (Talaee et al., 2014). Mexico has also demonstrated a recovery trend since 1990, and certain regions have even shown an upward trend (Brena‐Naranjo et al., 2017; Ruiz‐Alvarez et al., 2019). Additionally, a similar upward trend has been detected in Australia, parts of the U.S., Uruguay, and other regions (Abtew et al., 2011; Stephens et al., 2018; Vicente‐Serrano et al., 2018).…”

“…This situation is expected to be more pronounced in developing countries [1,3] in particular, those located in tropical, arid, and semi-arid regions, where agricultural activities are the main source of employment and income and where high temperatures are experienced already [4]. In these regions, the increased temperatures will raise water loss via evapotranspiration and intensify plant water stress, leading to poor harvests [2,5]. In addition to extreme temperatures, low and erratic precipitation, limited water availability, available agricultural practices in arid and semiarid agroecosystems are also limited [6].…”

Aims: Cactus pear cultivation for fruit production is under rainfed conditions, mainly. Hence, irrigation uses for this purpose is expensive in arid and semi-arid agricultural lands. The objective of this study was to derive agro-economic indicators associated with supplemental irrigation to improve fruit yield of commercial cactus pear cultivars grown in a semiarid agroecosystem of Mexico. Study Design: The irrigation treatments tested were fully irrigated (FI) and supplemental irrigation (SI), with non-irrigated as a control (NI). Place and Duration of Study: The experiment was set up at the Campo Experimental Zacatecas, Calera, Zacatecas, Mexico from 2011 to 2013. Methodology: Five-year-old cactus pear plants of ‘Cristalina’ (O. albicarpa Scheinvar; white-pulped fruit) and ‘Roja Lisa’ [O. ficus-indica (L.) Mill.; red-pulped fruit] were included. The experiment was conducted in a split-block design. There were three blocks; each included both cultivars, randomly allocated to each irrigation treatment. The response variables were: fruit yield (FY), cultivation costs (CC), gross return (GR), net return (NR), benefit-cost ratio (BC), irrigation use efficiency (IUE), gross water productivity (GWP), net water productivity (NWP), labor productivity (LP), break-even-point (BEP), and credit vulnerability (CV). Results: In all years but 2013, FI ‘Cristalina’ plants had the highest CC, reflected in their greater GR and NR; however, BC values were similar between SI and FI plants or greater in SI plants for 2013. Therefore, SI plants had the highest IUE, GWP, NWP, LP, EP, and equal or greater credit vulnerability than FI plants. The NI plants produced positive values for BEP and CV. The economic indices for ‘Roja Lisa’ were similar to those of ‘Cristalina’. Conclusion: The SI treatment produced the best agricultural economic indices and it is also a feasible water-saving irrigation strategy for cactus pear cultivation in semiarid agroecosystems worldwide.
