The objective of the study was to evaluate the social and environmental sustainability of the production system with Nunkini creole cattle in Campeche, Mexico. Ten production units (PU) were evaluated, in which sustainability was determined through a general mathematical model that quantifies principles and objectives of sustainable socioenvironmental development. The results of the model are expressed in a range of values from 0 to 10 and are classified as: Unsustainable, May be sustainable, Evolving, Evolving sustainable, and Highly sustainable. Of the ten PU, one (10%) is at the evolving level, seven (70%) are evolving sustainable, and two (20%) are highly sustainable. In conclusion, the local livestock production system tends towards socioenvironmental sustainability; however, it could be more efficient if social action and participation among producers is promoted.

Watersheds integrate a series of processes and environmental characteristics that are expressed in the morphometry of drainage networks. Morphometric analysis is key to understanding the functioning of the hydrological system of a basin. Its use is practical in areas with limited climatological information and a lack of knowledge about the functioning of the hydrological system. The main objective of this work is to characterize the geomorphology of the Grijalva and Usumacinta sub-basins in southeastern Mexico using geographic information systems (GIS) and a series of morphometric parameters associated with general characteristics, relief, drainage network, and the form of these sub-basins to analyze and understand hydromorphological behavior. The results obtained show some contrast between both basins around the parameter of the number of runoffs, which has implications in terms of energy and the capacity and magnitude of water collection of the sub-basin and the river network of both sub-basins. In this context, it is expected to contribute to local knowledge and the strengthening of decision-making in the areas of territorial planning, civil protection, infrastructure, and public policies.

In the complex system of urban social housing (VSU), eco-techniques are not used regularly, and the use of polluting energy systems is favored. By analyzing how to improve the efficient use of natural resources in the VSU, the cultural code was identified by implementing sustainable actions and eco-techniques to improve its habitability. This research was done with a mixed, exploratory, non-experimental, correlational, micro-ethnographic observation method, with a convenience and concurrence sample of 43 subjects who live in single-family homes. The results determined a significant correlation between environmental and economic efficiency in the use of eco-techniques and the meaning of their home. The cultural sense of the habitat promotes the incorporation of sustainable habits and technology, a vital point for its appropriation when valuing the use of natural resources, and it contributes to the social, environmental, and economic justice of the families under study.

Rice is a staple food in Mexico, predominantly grown in Nayarit, Campeche, and Michoacan. The coarse and long grain grown in Morelos has a designation of origin as Arroz del Estado de Morelos (Rice from the State of Morelos); however, there is less and less state agricultural area cultivated with this cereal. The objective was to analyze the actions taken by producers, millers, and marketers of Arroz del Estado de Morelos to position the grain in the market and to put forward proposals for improvement. The research was carried out in Jojutla, Morelos, obtaining information through semi-structured interviews, documentary research, and estimating profitability. The actions have involved the arts such as dance, literature, music, and photography, which complement the territorial identity of the cereal. Synergy between the three levels of government is necessary to strengthen the designation of origin and to position the grain in the market by highlighting its characteristic of being a seasonal agricultural product.

In Mexico, municipal governments are responsible for managing municipal solid waste (MSW). For these municipalities there is not an established scheme of parameters that is useful for estimating environmental governance in waste management. The state of Oaxaca is a federal entity with a significant lag in education and standard of living; it has 570 municipalities organized in eight regions. The objective was to generate a mapping that evaluates the status of MSW management in the municipalities of this entity, through a base of indicators. The results of the evaluation were low for 82% of the municipalities, while the only region with a passing evaluation was the Isthmus (28 points). In addition, a baseline of parameters that estimates environmental governance in waste management and is useful in other similar studies was proposed.

Covid-19 pandemic modified the working conditions of teachers who had to transfer their instruction to teleworking. This increased their mental workload (CMT) due to the demands of their activity and the resources to deal with this new condition. The objective of this research was to compare, according to the educational level taught, the CMT of Mexican teachers who worked in a telework modality during the covid-19 pandemic. A total of 112 teachers answered a socio-labor data questionnaire and the CMT-53 Godínez-Preciado scale. Results reported high levels of mental overload, demand for the activity, labor competence, and inadequate resolution of planned problems. In addition, in this last dimension, a significant difference was determined (F 2, 111 = 5.492, p = 0.005) between teachers in undergraduate programs compared to those teachers in secondary school.

One of the biggest current problems is climate change due to the concentration of greenhouse gases in the atmosphere produced by human activities. The objective of this research was to design strategies against climate change from a sustainability approach in order to contribute to decision-making in schools from Jalcocotán, aiming to reduce CO2 emissions associated with food consumption, transportation, and electricity consumption. To this end, CO2 emissions from food consumption, transportation, and electricity consumption were analyzed, the activity with the greatest impact was identified, and strategies were designed. Results show that the transfer to schools contributes with 73% of total CO2 emissions, food consumption with 24%, and electricity consumption with 3%. Finally, a reforestation and ecological mobility plan was implemented.

The objective of this research was to propose indicators and strategies to develop resilience to the new coronavirus (covid-19) in the independent restaurant sector in Mexico. To comply with this, the research method involved a descriptive analysis phase on the status of covid-19 and the measures and programs used to mitigate its impact on restaurants in Mexico City; additionally, a correlational analysis of the two-dimensional models of Prayag and Whitman was carried out. It is concluded that planning capacity and adaptability are positively and significantly correlated with resilience. Given this situation, the restaurants that will prosper during covid-19 in a new normal will be those that show interest in customers and employees; strategize recovery priorities and external resource skills and capabilities; and improve silo thinking, leadership, management and governance structures, as well as innovation and creativity.

Allogalumna (Acrogalumna) longipluma (Berlese, 1904) is a species with a wide distribution, reported for the first time in Mexican territory. The specimens were collected from soil samples from oak-pine forest and orchard planted with avocado (Persea americana) in the municipality of Uruapan, Michoacán. This work aims to provide more information on the biology, behavior, and morphology of all stages of development under laboratory conditions. The life cycle from oviposition to adult death was 217 ± 69.9 days, the egg stage had the longest duration of 10.1 ± 1.8 days, followed by tritonymph 9.4 ± 2.6; the adult life was the one with the greatest variability. Changes in size, morphology, sclerotization, ototoxic system and chaetotaxy of the body of juveniles and adults are described and illustrated.

An illustrated identification key to the North American termite families and genera based mainly on the soldier caste is proposed. A checklist of termites (Insecta: Blattodea: Isoptera) of Canada, continental USA and Mexico is presented, listing 89 species (and two subspecies) grouped in 26 genera and four families. Five species are added to the Mexican termite fauna, these records are for the states of Campeche: Cryptotermes cavifrons; Quintana Roo: Cryptotermes cavifrons, Neotermes holmgreni, Neotermes phragmosus, Neotermes mona; Sonora: Incisitermes banksi; and Yucatan: Neotermes phragmosus. Other 32 new state records are made for the states of Aguascalientes, Baja California Sur, Campeche, Chiapas, Jalisco, Nuevo Leon, Oaxaca, Quintana Roo, Sonora, and Yucatan. The species Coptotermes crassus, Coptotermes havilandi, Incisitermes perparvus, Microcerotermes strunckii, Nasutitermes costalis, Incisitermes nigritus and Termes melindae are eliminated from the termite fauna of this region.
