The coastal city of Guasave, Sinaloa, located on the Mexican Pacific coast, is subject to extreme precipitation events, which have caused flooding with damage to the city’s infrastructure. The factors that influence flooding are vegetation, geology, degree of soil saturation, drainage characteristics of the watershed, and the shape of the topographic relief. Of the above factors, the topographic relief, which is the subject of the study, has been partially modified in some areas by infrastructure works (from 20.2 m to 17.6 m), and the population of the urban area has grown by 51.8% in 17 years (2004–2021); therefore, the objective is to evaluate the potential flood risk due to changes in this factor and the growth of the urban area. When using this method, the potential flood risk was determined considering four extreme events, 1982, 1990, 1998, and 2019. It was found that the potential risk increases for the whole city, being more intense in sector III, which, before the modification of the topographic relief, was the area with the lowest risk of flooding. In an extreme event such as Hurricane Paul in 1982, practically the entire city would be flooded.

The analysis of the economic problems of the population in Latin America in the face of unemployment and inflation, which have become permanent in these economies, gives rise to the generation of proposals for the solution of social deficiencies, as well as sustainable factors that govern the behavior and culture of production today. The objective was to establish the importance and contribution that backyard activities can have to reach positive socioeconomic and nutritional levels in the rural area of the municipality of Guasave, Sinaloa, Mexico. An exploratory analysis was carried out, to diagnose the problem, applying interviews to describe the socioeconomic and backyard perspectives, finding that more than 70% of those consulted carry out this activity in relation to livestock and/or agricultural dynamics. Two variables with positive economic effects stand out: self-consumption and commercialization, which are relevant socioeconomic aspects in the relationship between production and family economy, as well as the promotion of self-employment and preservation of family traditions in rural communities.

Arid and semi-arid zones frequently present salinity problems in soils. The agriculture of the municipality of Ahome, Sinaloa has an agricultural region where its soils are characterized by problems of salinity and sodicity – conditions that reduce production. Salinity can be detected by implementing remote sensing techniques; there are ways to enhance the detection of satellite salinity through the use of diverse quantitative models, using the spectral signature of each of the components of the study area through algorithms named indices. For this study we used the normalized differential salinity index (NDSI) from a Landsat OLI image for the southern area of the city, which is related to the electrical conductivity (EC) of the soils (R = 0.90). At the same time, it is related to some anions and cations. As a result, it is possible to determine since the NDSI, the anion Cl– and Cations Na+, Ca++, and Mg++. We found a relationship between EC - Cl– (R = 0.94), EC - Na+ (R = 0.84), EC - Ca++ (R = 0.85), and EC-Mg++ (R = 0.86). The electrical conductivity in the field and laboratory, anions, cations, and NDSI index were filtered with the Kalman filter obtaining better fitter, eliminating dispersivity in the variable relations.

Isolation due to the COVID-19 pandemic has heightened daily tension, leading to stress and other illnesses. This research examined the impact of backyard activities on social and personal well-being, focusing on agricultural (gardens, vegetables, medicinal plants) and livestock activities (chickens, goats, sheep, cows). An exploratory study was conducted using a Likert-scale survey of 387 people, with 22 items covering economic growth, social well-being, and human development. The results showed that 50% of the respondents experienced pleasant emotions through sensory engagement with home gardens, leading to well-being, reduced anxiety and stress, better concentration, and improved family harmony. McDonald’s Omega (ω) value for item consistency was 0.964. Strong correlations were found between economic growth, social well-being, and human development with social and personal well-being, at 0.719, 0.819, and 0.812, respectively. These results are validated by an exploratory principal component factor analysis, which shows the correlation of the classes that integrate backyard activities on a principal axis. Backyard livestock activities had a lesser impact on personal and social well-being compared to agricultural activities, which were valued more for their economic and nutritional contributions. Thus, backyard activities, especially those involving home gardens, significantly enhance social and personal well-being alongside their economic and food benefits.

Aquaculture is one of the fastest growing productive sectors in recent years, so much so that it has surpassed traditional fishing. The aim is to make its production processes sustainable, mainly economically and environmentally, through continuous innovation. Hence, the objective is to determine the relevance of sustainable innovation management in the shrimp sector in the municipality of Guasave, state of Sinaloa, Mexico, as a determining factor in the search for social and environmental well-being in this region of the Mexican Pacific. With this in mind, the present research was designed as an exploratory–explanatory study, under a qualitative approach with a multiple case study strategy using the Likert scale. To this purpose, 24 surveys were applied to the owners and managers of six farms specializing in shrimp production, with a continuous production of 10 years and a minimum of 100 hectares cultivated in recent years. Each survey consisted of seven themes and a total of 37 items to analyze eight indicators which influence the sustainable innovative management of the shrimp sector. The survey results indicate that the perception of entrepreneurs toward the relevance of sustainable innovation management is favorable, with 96% agreeing to encourage innovation, 83% agreeing to invest in new equipment and methods, and 83% in favor of their participation in markets. Moreover, the correlation between the indicators to determine the influence of sustainable innovation management is significant at 0.69 and 0.86.

The COVID-19 pandemic impacts, worldwide, the daily activities of the population, in view of this, various preventive measures have been adopted to reduce the risks of contagion. In the educational field in Mexico, face-to-face classes have been suspended, adopting the use of electronic platforms; this, to avoid the risks of contagion. Measures like the aforementioned, the use of face masks, gels, healthy distance, face shields, among others, are already part of the daily routine. However, the level of perception, responsibility and behavior in the face of these measures by the various sectors of the population is unknown. In this study, the perception of high school and university students from Guasave, Sinaloa, Mexico is analyzed. To know the aforementioned aspects, a descriptive cross-sectional study was carried out using the convenience sampling technique, applying a survey made up of 18 items of Likert-type, designed on the Google Forms platform, to a sample of 940 students of both sexes, in 10 public and private schools. The results show that, more than 50% of the students of both educational levels, have a perception that deviates from reality, they do not measure the importance of the preventive measures that the health sector recommends to reduce the contagion and lethality rate. Despite recognizing that the viral disease is contagious, they do not perceive the importance of measures such as washing hands with soap, using gels, masks, face masks, maintaining a healthy distance, among other sanitary measures. They assume the measure of confinement as necessary, although it generates stress and a decrease in their academic performance, reflected in low grades. The results found in the studied educational sector indicate that the educational authorities should strengthen the scientific learning of the students in relation to the epidemiological phenomenon of covid-19, in order to contribute to their conduct and implementation of health protection measures and prevention of this scourge.
