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.

Backyard activities (BAs) constitute a traditional rural food production strategy, although their sustainability-related outcomes remain underexplored in rural contexts. Our objective is to analyze how BAs in rural communities in the municipality of Guasave, Sinaloa, Mexico, represent a local strategy for producing healthy food through sustainable practices, focusing on the relationship between production processes and indicators associated with waste management, water use, and environmental impact. A stratified sampling approach was employed, and a structured survey was administered to 387 households practicing BAs in the region. Instrument consistency was verified using the Kuder–Richardson coefficient. Results show that BAs are relevant in the region: 89.15% of respondents have a family garden and 67.96% raise animals for domestic consumption, supporting an additional income. Chi-square tests revealed statistically significant correlations (p < 0.05) among the study variables, ranging from moderate to strong, with backyard animal husbandry practices standing out in relation to nutritional and health management in animal production, reaffirming that these are not isolated events but complementary activities. These findings indicate that BAs involve interconnected systems rather than isolated activities, reflecting an integrated household-level system with potential implications for resource management and environmental sustainability in rural contexts.

The cultivation of yellow plum (Spondias purpurea) represents a traditional resource with potential for utilization in rural communities of the municipality of Guasave, Sinaloa, Mexico. The objective of this study was to analyze the food relevance and utilization potential of yellow plum cultivation in rural households by characterizing the socioeconomic profile of families, estimating domestic production levels, and identifying the uses and final destination of the fruit. The research was conducted using a mixed, descriptive, and cross-sectional approach, based on the application of 167 surveys to rural households. The results reveal a high presence of fruit trees in backyard systems, with significant production of yellow plum primarily intended for self-consumption. However, the findings also indicate the existence of production surpluses, low levels of processing, considerable fruit waste, and limited participation in commercialization activities, despite a favorable willingness among households to market the product. It is concluded that yellow plum production in rural backyard systems plays an important role in food security and exhibits an underutilized economic potential. Its full utilization requires strengthening productive capacities, improving access to processing technologies, and developing appropriate marketing channels, as well as the implementation of public policies aimed at supporting backyard production systems.

En los espacios de la vida rural, donde la tierra se convierte en sustento y tradición, el traspatio emerge como un sistema productivo lleno de significado. Más allá de su aparente sencillez, representa una estrategia clave para la seguridad alimentaria, la diversificación de ingresos y la preservación de conocimientos que se trasmiten de generación a generación. “Diversidad productiva de traspatio y bienestar social en comunidades rurales” ofrece una mirada integral a estas prácticas, articulando fundamentos teóricos, evidencia empírica y propuestas de capacitación orientadas al desarrollo sostenible. A través de un enfoque multidisciplinario, se exploran las dinámicas sociales, económicas y ambientales que configuran el traspatio como un eje de resiliencia comunitaria. Este libro está dirigido a personas de comunidades comprometidas con el desarrollo rural, a académicos, a estudiantes y a aquellos interesadas en comprender y fortalecer las capacidades locales. En sus páginas, el lector encontrará no solo análisis rigurosos, sino también herramientas prácticas que contribuyen a impulsar modelos de producción más justos, inclusivos y sostenibles. Porque en cada traspatio hay más que producción: hay identidad, conocimiento y futuro.

Marine turtles are key species for the stability of coastal and oceanic ecosystems; however, their conservation faces increasing pressures derived from climate change and anthropogenic activities. This study analyzes the perception of the academic and scientific community in biology, environmental sciences, and marine sciences regarding marine turtle conservation along the coast of Sinaloa, Mexico. A quantitative cross-sectional survey-based study with an exploratory approach was employed, using a Likert-scale questionnaire administered to 358 participants. The instrument demonstrated adequate internal consistency (α = 0.836; ω = 0.827). An exploratory factor analysis (EFA) using principal component extraction identified four components explaining 55.51% of the total variance, corresponding to four dimensions: (1) commitment to conservation, (2) environmental and climatic impacts on reproductive processes, (3) key factors and threats in the reproductive cycle, and (4) conservation practices and knowledge. Results suggest a general tendency toward agreement on the ecological importance of marine turtles and the threats affecting their reproductive success, particularly climate-related and habitat degradation factors. However, greater variability was observed in perceptions related to applied practices and technical knowledge, indicating differences in perceptions related to the implementation of conservation strategies. These findings suggest the potential relevance of strengthening applied training, interdisciplinary collaboration, and knowledge transfer mechanisms to enhance the effectiveness of conservation initiatives in priority nesting areas of Sinaloa.
