“…Moreover, the plants are intercropped with various food crops in diversified agroecosystems, increasing the presence of beneficial flora and fauna (including pollinators), which in turn helps to reduce the incidence of pests, conserve ecosystem services and protect water resources (Lucio, 2018; Torres, 2018; Zizumbo Villarreal et al, 2009). Agroecological forestry management maintains and fosters a diversity of species and varieties of agave, not only for productive purposes but also for their ecosystem functions in controlling erosion, maintaining humidity, promoting associated fauna, sequestering CO 2 and favouring edaphic biodiversity (Nobel, 2011; Reyes‐Jaramillio, Chimal‐Sánchez, Salmerón‐Castro, Vázquez‐Pérez, & Varela‐Fregoso, 2019).…”

This article seeks to challenge the notion that the concept of agro‐extractivism be restricted to crops destined for export with little or no processing. Based on a study of agave and tequila production in Mexico, it argues that the domestic processing of biomass does not change nor necessarily compensate for the negative social and environmental impacts of upstream agricultural activities; it can in fact add to them. We seek to demonstrate this to be the case for industrialized agave–tequila production by adopting an approach that traces the flows of materials, pollutants and money, taking into consideration the degree to which transnational companies control the agave–tequila value chain, the portion of tequila that is exported, technologies, company–farmer and company–worker relations, relevant public policy, and environmental and social impacts. We analyse the polluting consequences of industrialized tequila production and show how the expansion and intensification of agave production since the mid‐1990s has been characterized by increasing volumes of biomass extraction, the emergence or exacerbation of different forms of environmental degradation, the marginalization of small‐scale agave farmers, and deteriorating working conditions for agave‐field workers. In addition, we briefly discuss traditional mezcal production as a socially and ecologically sustainable alternative model.

Checklist of the arbuscular mycorrhizal fungi of Oaxaca, an important hotspot of biodiversity in Mexico

et al. 2023

Background: Oaxaca, a southern State in Mexico, belongs to the Mesoamerican hotspot of biodiversity. The taxonomic and diversity knowledge of arbuscular mycorrhizal fungi (AMF) in Oaxaca State is scattered and accessibility to it is difficult. Questions: Which AMF species have been identified in Oaxaca and which is their distribution? Studied species: Arbuscular mycorrhizal fungi. Study site: State of Oaxaca, Mexico. Methods: It was prepared an updated and annotated checklist of the AMF species with frequency of occurrence and the sampling sites where the species had been registered. All studies carried out previously (to date, 2022) were considered. Information on AMF taxa was available in scattered form in different publications in physical and electronic media, theses, projects, technical reports, and scientific papers. Results: The checklist includes 78 species, distributed among 23 genera, 10 families, and four orders. The most diverse families were Glomeraceae (26 species), followed by Gigasporaceae (20) and Acaulosporaceae (15), whereas the most diverse genera were Acaulospora and Glomus (15 and eight species, respectively). The most frequent species were Funneliformis geosporus, Acaulospora scrobiculata, and A. spinosa. The highest species diversity has been reported under the rhizosphere of Agave angustifolia, A. karwinskii, and Zea mays (39, 36, and 34 species, respectively). A new AMF species was recently isolated from the rhizosphere of a microendemic agave. Conclusions: The recorded AMF species of Oaxaca State confirms its position as one of the states with the highest AMF species diversity of Mexico.
