Situated learning through local stories: positioning socio-ecological concerns, knowledge and practices in school

Rosa Guadalupe Mendoza Zuany Juan Carlos A. Sandoval Rivera Paula Martínez Bautista (2023, [Artículo, Artículo])

The article analyzes the importance of the local stories, which contain concerns, knowledge and practices to look after the socio-ecological environment, to trigger situated and pertinent teaching and learning processes in primary education in rural and indigenous contexts in Veracruz, Mexico. In particular, it focuses on the stories about care in the framework of a deep socio-ecological crisis in two Nahua communities of the Huasteca region. Interview-conversations were carried out with community actors in the two communities in which 32 stories emerged. The analysis allowed the identification of socio-ecological concerns of the community, characteristics of the stories that show their potential in the learning processes, as well as types of knowledge and practices that are rarely considered in the classroom, which are capable of being linked to curricular content, in order to contribute to reflection and action on the socio-ecological crisis of the communities.

Influence of novel coconut oil and beeswax edible coating and MAP on postharvest shelf life and quality attributes of lemon at low temperature

Mohammad Mainuddin Molla Ashfak Ahmed Sabuz Md Abdul Matin (2023, [Artículo])

Weight loss, turning of peel colour from green to yellow and microbial infections are the major postharvest problems of lemon. Lipid-based edible coatings and modified atmospheric packaging (MAP) are effective techniques in maintaining postharvest quality of fruits for long-term storage. With this view, an investigation was conducted for the preservation of green lemon using coconut oil and beeswax edible coating and MAP during storage at low temperature. Physiologically matured lemons were collected and washed with potable water; fruit surface water was removed and then coated with coconut oil-beeswax (90:10) or only coconut oil. After coating, lemons were packaged in MAP or kept in open crates and stored at 12±1 °C and 85±5% relative humidity (RH) for 8 weeks and a week interval, the sampling was conducted. The results revealed that coconut oil-beeswax coating had immense effect on retaining shiny green colour, reducing respiration, weight loss, shrivelling and preserving firmness and ascorbic acid of lemon throughout the storage. On the other hand, MAP mainly helped to retain moisture & firmness and reduce shrivelling. Uncoated lemons kept open lost the highest amount of ascorbic acid and retained only 13.7 mg/100 g that is significantly (p < 0.05) less than the lemons of all other treatments at 8th week of storage period. While lemons coated with coconut oil-beeswax and packaged in MAP was preserved the highest amount (24.2 mg/100 g) of ascorbic acid and there was no significant difference (p < 0.05) with the amount of ascorbic acid content of lemons coated with only coconut oil and packaged in MAP at the last week (8th week) of storage. Hue angle value was 93.4 in uncoated lemons packaged in MAP while it was 113.67 in coconut oil-beeswax coated lemon kept open and 112.64 in lemon coated with coconut oil-beeswax and packaged in MAP at 8th week of storage. Based on all sensory, physical and chemical parameters uncoated lemons kept open was acceptable up to 1 week, coconut oil-beeswax coated lemon kept open was 6 weeks and coconut oil-beeswax coated lemon packaged in MAP was 8 weeks with good quality and shiny green colour.

Illustrative power and epistemic roles of the image in multi-disciplinary researches on poverty contemporary Habitat

Peter Krieger (2023, [Artículo, Artículo])

This study analyses the epistemic functions of images in the geographic and sociological discourses on poverty habitat in the megacities of the global south by focusing on Mexico city. Based on a conceptual and methodological review of art history from Bildwissenschaft perspective (visual studies), this paper aims to examine the poverty habitat by describing its typologies, patterns, encodings and possible effects of its visual constructions. This contribution outlines the utility of this type of research, the function of inter and transdisciplinary studies in this field and its fundamental ethic dimension.

Surviving “la lucha” in Ciudad Juárez. An Anthropological reflection on the cuban community in Ciudad Juárez, México

Stephanie Morales Victor Vazquez (2021, [Artículo, Artículo])

The following article presents a brief anthropological and historical reflection based on the Cuban community in Ciudad Juárez, Chihuahua, México. Additionally, we discuss important historical aspects that have contributed to the development of the Cuban community in El Paso, TX-Ciudad Juárez, CH border, such as the migrant caravans that occurred between 2017-2019 and the migratory policies that have been put into effect. Furthermore, we present an ethnographic analysis on the migration experience of certain participants, placing an emphasis on created networks, and expanding on the concept of community through spatial solidarity and survival in Ciudad Juárez.

Sustainability evaluation of contrasting milpa systems in the Yucatán Peninsula, Mexico

Santiago Lopez-Ridaura Tania Carolina Camacho Villa (2023, [Artículo])

The milpa agroecosystem is an intercropping of maize, beans, squash and other crops, developed in Mesoamerica, and its adoption is widely variable across climates and regions. An example of particular interest is the Yucatan Peninsula in Mexico, which holds highly diverse milpas, drawing on ancestral Mayan knowledge. Traditional milpas have been described as sustainable resource management models, based on long rotations within a slash-and-burn cycle in forest areas. Nevertheless, due to modernization and intensification processes, new variants of the approach have appeared. The objective of this study was to evaluate the sustainability of three milpa systems (traditional, continuous, and mechanized) in four case studies across the Peninsula, with emphasis on food self-sufficiency, social inclusion and adoption of innovations promoted by a development project. The Framework for the Evaluation of Agroecosystems using Indicators (MESMIS, for its Spanish acronym) was used for its flexible, participatory approach. A common group of indicators was developed despite regional differences between study cases, with a high level of farmer participation throughout the iterative process. The results show lower crop yields in traditional systems, but with lower inputs costs and pesticide use. In contrast, continuous milpas had higher value in terms of crop diversity, food security, social inclusion, and innovation adoption. Mechanized milpas had lower weed control costs. Profitability of cash crops and the proportion of forest were high in all systems. Highly adopted innovations across milpa types and study cases included spatial crop arrangement and the use of residues as mulches. However, most innovations are not adapted to local conditions, and do not address climate change. Further, women and youth participation is low, especially in traditional systems.

Victor Vazquez Ashley McAfee (2021, [Artículo, Artículo])

The following article presents an anthropological and historical reflection on the Puerto Rican inner-city neighborhood better known as “Los Sures” in South Williamsburg, Brooklyn, New York City (nyc). The analysis will explore the contemporary academic discussion regarding the following concepts: poverty, the welfare State, the discourse surrounding welfare recipient’s culture, inner-city living conditions, and the current context of gentrification. Methodologically, the article presents an ethnographic reflection based on fieldwork experiences and interviews conducted on residents of the previous “Los Sures” and still living in nyc. Finally, we present&nbsp;a critical reflection on the poverty, welfare State policy, and shed light on the difficulties faced by Puerto Rican migrants and their struggle to preserve the Puerto Rican legacy in the now nyc and gentrified “Los Sures”.
