Vinasse is a toxic pollutant if it is poured into the ecosystem indiscriminately; despite this, it integrates components that make it valuable in nutrients and water. However, its use has been questioned due to the costs involved in its purification. This systematic review focuses on the valorization of vinasse from the studies performed for its post-industrial use. Trends in vinasse management and bioproduct development were analyzed. The PRISMA statement was used as a formal guide for collecting and analyzing 131 studies from 2018 to 2022. We determined that biological processes are the most used to obtain the benefits of vinasse, obtaining up to three post-industrial bioproducts. While it is true that there is a predominant trend of studies focused on the generation of biofuels, it must be noted that the beginning of the sucro-alcohol chain was the agricultural field. In this sense, we determine that 14% of the studies treat vinasse for agricultural reuse purposes, so, under Circular Economy principles, the reincorporation of vinasse into the agricultural field to take advantage of its goodness in nutrients and minerals as a sustainable and eco-efficient alternative should be a research trend that accelerates the consumption of vinasse generated in alcohol distilleries.

Conventional aquaculture (ACUA-C) in Mexico is an activity that maintains an annual growth rate of 6%. Tilapia (Oreochromis niloticus) aquaculture is the predominant aquaculture in the country with 4623 farms, most of which operate with semi-intensive (SIS) and extensive (ES) production systems, discharging untreated wastewater that negatively impacts the environment. To address this problem, new ecotechnologies such as biofloc (BFT), recirculation systems for aquaculture (RAS), constructed wetlands (CWs) for water treatment, and aquaponics (AS) have emerged to mitigate the environmental impacts of untreated wastewater. The objective of this work is to evaluate the feasibility of tilapia farming with BFT, RAS, CW, and AS ecotechnologies through an economic and financial feasibility analysis, considering their environmental and social implications in a Mexican aquaculture farm located in the state of Veracruz. Open interviews, direct observation, and diagnosis of the semi-intensive tilapia system was carried out between 15 May 2019 and 15 February 2020 in order to calculate, design, and theoretically evaluate the four ecotechnological alternatives (TBF, RAS, CW, and AS). Economic (13), environmental (10), and social (5) variables were applied, making use of the same facilities. The results reveal that the four ecotechnologies implemented in an SIS are economically viable and environmentally acceptable, especially in water management, in addition to being socially feasible. It is concluded that BFT offers an alternative to the producer by having a lower additional cost to improve problems, despite the possible complexity of operation and energy requirements to manage wastewater treatment. The technological transition to BFT is recommended to solve the problem of sustainable water management.

Diversas notas de portales electrónicos, documentales y en menor grado artículos de corte científico, han reportado el interés por mejorar el rendimiento de producción de miel por colmena. Entre estos trabajos pueden encontrarse reportados, en su forma dimensional, factores climáticos, sociales y tecnológicos, en donde expertos y especialistas reconocen que contribuyen a mejorar la producción de miel. Apoyado de expertos apícolas, del método Delphi y el análisis estructural MICMAC, en este artículo se reporta la influencia y dependencia de 22 variables y su relación directa e indirecta con la producción de miel en la región intermunicipal de Misantla del distrito apícola núm. 52. Las variables con base en MICMAC se clasifican en clave, reguladoras, palanca y autónomas. En el plano estratégico, la ‘ubicación del apiario’ relacionado con la ‘diversidad de floración melífera’ y el ‘tiempo que transcurre entre la colocación del apiario y la cosecha de miel’, representan las variables clave con mayor valor estratégico de 75/79, 61/79 y 63/79, respectivamente. Si bien, la ‘floración de especies melíferas’ es una variable clave para producción de miel, el resultado también indica que esta variable no es una determinante para que el apicultor decida la ‘ubicación de apiarios’. Estos resultados aportan conocimiento en cuatro categorías de variables influyentes en la producción de miel para que el apicultor reflexione sobre sus practica apícolas y pueda diseñar estrategias y tomar decisiones, para mejorar el rendimiento de producción miel.

The central-northern region of Veracruz has experienced significant changes in traditional coffee cultivation and cattle raising due to the increased demand for fresh and industrialized citrus products. However, there is a lack of understanding regarding the use of agrochemicals in citrus production, driven by the belief that “more is better” and a limited awareness of responsible agricultural practices. This research examines citrus crop management in rural communities, focusing on farming practices aimed at improving production by controlling pests and diseases. Data for this study were collected from 51 producers through in-person surveys, using a 48-item questionnaire and the snowball sampling method. The findings reveal that despite 20 years of development, citrus production is still not fully established, and the excessive use of agrochemicals remains widespread. The expansion of citrus groves in the study region has altered the agricultural landscape and the socioeconomic structures of rural communities. Furthermore, environmental concerns about chemical residues in the fruit limit their commercialization and harm the environment through runoff into groundwater and water bodies. To address these issues, it is crucial to raise awareness and guide farmers toward the responsible use of chemicals in citrus cultivation, ensuring sustainable production and mitigating negative environmental impacts in all communities where citrus is grown.
