One of the climate problems that causes the most environmental impact worldwide is the trend of increasing occurrence of events of maximum extreme temperature, signaled by indicators such as hot extremes (HE) and maximum maximorum (highest maximum) temperature (MmT). These events can cause conditions ranging from severe droughts to heat stroke, which can cause death in any population. Indicators of maximum extreme temperature in one of the most important agricultural areas in northwestern Mexico were calculated based on significant trends (ST) and adjusted return periods. To calculate the trends of the maximum extreme temperature, frequency (FR), annual average duration (AAD), annual daily duration (ADD), intensity (IN) of HE, and MmT, the Mann-Kendall and Sen’s slope tests were applied to data obtained for 19 weather stations from the CLImate COMputing database for the period 1982–2014. Adjusted return periods (ARP) were calculated for each indicator of maximum extreme temperature by fitting a probability distribution function. For the study area, the ST and maximum extreme temperature shows a prevailing cooling trend. This can be deduced by observing the proportion of negative ST compared with positive ST. The highest positive magnitudes of ST were recorded at stations CUL (FR = 3.44 HE dec-1), GUT (AAD = 6.15 day HE-1 dec-1 and IN = 13.62 °C dec-1), IXP (ADD = 35.00 day dec-1) and POT (MmT = 2.50 °C day-1 dec-1). For ARP, the estimate of the average occurrence frequency of extreme events per100 years are FR = 6.11 HE dec-1 (1 time), AAD = 6.64 day HE-1 dec-1 (4 times), ADD = 38.68 day dec-1 (1 time), IN = 39.09 °C dec-1 (6 times) and MmT = 41.95 °C day-1 dec-1 (1 time). These findings are of key importance for the economic sectors related to agricultural production in the state known, at least to date, as “the breadbasket of Mexico” (Sinaloa). The results will help to develop adaptation/prevention measures before the coming socioeconomic and hydrological disasters.

“…The main factors that contribute to establishing these enterprises include the technological level and the current form of organization within companies [50]. These characteristics allow them to increase their production, which are mainly exportoriented crops [51]. However, strong pollution problems and environmental costs have been accentuated due to the application of fertilizers and pesticides as well as inputs contained in the technological packages [52].…”

The Productive Orientation of Rural Extensionists in the Regions of Mexico: A Key Element for Agroecological Transition

Considering the agroclimatic and social diversity of Mexico, this paper starts by recognizing the potential of rural extensionists within a policy framework of agroecological transition in the country. This paper identifies the types of productive positioning (agroecological vs. conventional) of rural extensionists located across the diverse states and socioeconomic regions of Mexico. This data is intended to outline particular features for the differentiation and targeting of regional strategies to train extensionists according to their regional context. We analyzed 1448 questionnaires gathered in 2019 via the online platform SurveyMonkey from rural extensionists enrolled in the Mexican Rural Extension System (SERMexicano). The results revealed that extensionists mainly identified themselves with the agroecological model. However, a significant proportion across states and regions still associated themselves with the conventional model. Three types of trends were recognized in relation to the positioning of extensionists, namely agroecological, towards neutrality, and contrasting. According to the socioeconomic regions where extensionists are located, diverse inter- and intraregional nuances among these positionings were also identified. Finally, we conclude by emphasizing the need for this heterogeneity to be considered in order to design and implement programs aimed at transitioning and expanding agroecology in Mexico.

“…The production of fruit and vegetable crops has grown substantially in Mexico. Crops such as avocado, papaya, pepper, brassicas and berries have been produced for 10 years under a wide variety of climatic and soil conditions (Macías-Macías, 2010;Valencia-Sandoval, Duana, and Hernández, 2017;Fiscal, Restrepo, and Rodríguez, 2017;González-Razo et al, 2019). The management of nutrients applied through fertigation is an important aspect to consider in maximizing yield and quality of fruits and vegetables (Maboko and Du Plooy, 2017).…”

Crop fertilization greatly impacts food production. However, insufficient applications can lead to poor yields. On the other hand, an excessive application leads to soil and aquifers pollution. In this paper, field studies were carried out to determine the ranges of mineral concentration and the interaction of the ions in the soil solution (SS) and the petiole cellular extract (PCE) in several cultures established in the states of Guanajuato, Colima and Jalisco, Mexico. The hypothesis states that there is a causal relationship between the mineral composition of the soil solution (SS) and the minerals and total soluble solids (TSS) in petiole cellular extract (PCE). The following cultures were studied in this research: avocado, blueberry, broccoli, cauliflower, raspberry, strawberry, lettuce, cantaloupe, papaya, and pepper. For each culture, PCE samples and SS samples using a press to break tissue and ceramic tip lysimeters were obtained. The results were processed to obtain ranges of variation within 50% of the closest values to the median. Correlations between the several ion concentrations were analyzed using analysis of variance. The results showed values (mg L-1) of NO3- (40-620), PO43- (17-66), K+ (3-377), Ca2+ (27-582), Na+ (15.3-500), Mg2+ (10-53), Fe3+ (0.6‑1.8), and Zn2+ (2.8-7.4) in soil solution, which allowed obtaining values of NO3- (27-9225), K+ (820-9375), Ca2+ (1.0-650), Na+ (25-620) and TSS (2-13 °Brix) in petiole cellular extract of petiole. Statistically significant correlations were observed between the concentrations of the SS ions regarding the concentrations in PCE in crops suggesting a relationship between the plant nutritive assimilation and cations or anions present in soil solution. The conclusion derived from this study is that ionic concentration ranges registered in the SS and in the PCE provide an approximation to the ranges of nutritional sufficiency for the horticultural crops established in the summer-winter in western Mexico.
