The Multifunctionality of Rural Backyards: Producing Healthy Food Through Sustainable Practices in Households—A Study in Guasave, Sinaloa, Mexico

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.
