Choconta is the municipality in Colombia with the greatest prevalence of potato planting, representing 70.90% of the total territory. However, this crop has been affected by the presence of pests, diseases, and chemical contaminants from pesticides and chemical fertilizers that deteriorate the soil and, therefore, the quality of the final product. Compost (organic waste with specific characteristics and made from waste generated in Choconta) was studied as a sustainable production strategy to increase soil quality and thereby the quality of the local potato crop. For this purpose, a 3 × 2 experiment design was implemented with three treatments (0%, 25%, and 50% compost) and two variables (young potato and mature potato) in duplicate for 4 months. In this experiment, the use of compost led to an improved final product, which went from a floury texture to a dense and creamy texture. The use of compost also reduced the levels of heavy metals, such as lead, with a higher removal in treatment 3 (50% composting). The estimated direct cost of the composting process was USD 280.85, slightly lower than that of the application of fertilizers at USD 294.48. The use of fertilizers has a higher environmental impact due to the use of chemical products that have environmental and health implications. Using compost did not influence tuber harvest time but had a positive impact on tuber texture quality and on soil resources through the reduction in heavy metals, especially lead (16.40–18.03 ppm for treatment 1, 17.96–18.49 ppm for treatment 2, and 15.67–17.88 ppm for treatment 3). Using compost could be environmentally and economically beneficial for local farmers, and it promotes the circular economy and sustainable communities.

A business solution is proposed for the accumulation of waste in the Municipality of Choco without prior treatment through the establishment of a center for the reception, classification, recovery and use of solid plastic waste in the Municipality of Quibdo, which would optimize and expand the management of plastic waste. In this study, the basic diagnosis of the practices that are currently carried out in Quibdo is evaluated with the appropriation of the knowledge of the population, the technical structuring of the conditions of production of plastic wood is carried out from the management of plastic waste, recognition of the market for waste generated as an alternative for development and sustainable growth and the financial feasibility of the project and the profitability of each of the investment plans for its implementation. The results of the investigation include the identification of weaknesses and opportunities in waste management practices and the proposal of two investment plans for the establishment of the center. It is concluded that investment plan 2 would require 46,590.50 USD less than investment plan 1, equivalent to a 2.21% return compared to investment plan 1.

Historically, agriculture has been a key driver of rural development. Therefore, outlining strategies that enhance agricultural production for economic sustenance, quality of life, and the durability of natural resources puts us on the right path to ensure sustainability. This is the focus of the green business model proposal, which aims to provide farmers with tools to strengthen their daily activities while preserving the ecosystem, ensuring that future generations can enjoy its benefits. Opening a marketing channel under green business guidelines for iceberg lettuce as a biofortified food crop in the municipality of Chocontá in Cundinamarca, Colombia, is an innovative approach to addressing food security issues. Currently, 24.8% of households in 23 cities consume two meals a day or fewer. This proposal also seeks to influence crop rotation in the municipality, helping to mitigate soil degradation in the area.

Lack of food security is a major threat at the local and global levels. This research focused on the design and implementation of a school garden at Carlos Albán Holguín school as a strategy to ensure food for vulnerable communities and promote environmental education. This project was structured in six stages including diagnosis, characterization, formulation, and pilot validation. Data were collected through surveys and checklists, which evaluated the garden’s conditions and students’ understanding of environmental practices. Key findings revealed significant improvements in students’ knowledge of sustainable agriculture upon implementing the garden, with 75% demonstrating outstanding comprehension and 80% effectively applying organic farming principles. Promoting and implementing urban agriculture benefits surrounding communities, reduces environmental impact, promotes social awareness of current food security challenges, and promotes economic growth in cities. The main conclusion of this research is that integrating environmental education within the school curriculum can significantly enhance food security and foster environmental stewardship. This research underscores the importance of sustainable urban gardens in addressing nutritional deficiencies and promoting sustainable agriculture practices in urban settings.

La obra que el lector tiene en las manos conjuga el esfuerzo de un grupo de investigadores en México y Colombia, un intento por establecer un trabajo que subraye la importancia de promover campos concretos de análisis y respuestas a los problemas que acompañan los espacios desiguales y se tornen en oportunidad de conocimiento. El manuscrito espera ofrecer una mirada multidisciplinaria sobre la sostenibilidad y los procesos de desarrollo sostenible, más allá de los discursos, y facilitar coyunturas específicas para su entendimiento.

En el presente trabajo, se parte de destacar cómo en los espacios de vulnerabilidad que se tienen en el estado deGuanajuato, particularmente en la Sierra Gorda de Guanajuato, donde los impactos provocados por el cambio climático, han permeado en las comunidades y se han gestado grandes problemas socioambientales. Ante ello, se presenta el trabajo realizado a través de la cartografía participativa como una herramienta que permita establecer estrategias de solución colaborativa en escala local, particularizando en las prácticas y conocimientos compartidos.
