    This study explores the spatial and social implications of urban food systems in Quito, Ecuador, focusing on how food access inequalities reflect and reinforce broader urban disparities. The research addresses a critical problem in contemporary urbanization: the disconnection between food provisioning and spatial equity in rapidly growing cities. The objective is to assess and map disparities in food accessibility using a mixed-methods approach that includes field observation, participatory mapping, value chain analysis, and statistical modeling. Five traditional and emerging food markets were studied in diverse districts across the city. A synthetic accessibility function F(x) was constructed to model food access levels, integrating variables such as income, infrastructure, transport availability, and travel time. These variables were subjected to Principal Component Analysis (PCA) and hierarchical clustering to generate three typologies of territorial vulnerability. The results reveal that peripheral areas exhibit lower F(x) values and weaker integration with the formal food system, leading to higher consumer costs and limited fresh food options. In contrast, central districts benefit from multimodal infrastructure and greater diversity of supply. This study concludes that food systems should be treated as critical urban infrastructure. Integrating food equity into land use and mobility planning is essential to promote inclusive, sustainable, and resilient urban development.

    La arquitectura ha evolucionado significativamente a lo largo de la historia, trascendiendo el diseño de edificaciones para abarcar dimensiones urbanas, sociales, medioambientales y tecnológicas. En el marco de las crecientes demandas de sostenibilidad y digitalización, este estudio tuvo como objetivo determinar el nivel de desarrollo científico de alto impacto en la convergencia entre arquitectura y desarrollo de software, aplicada a los sistemas alimentarios urbanos. Se adoptó una metodología cuantitativa de carácter bibliométrico, basada en la base de datos Scopus, que permitió analizar un conjunto de variables clave: autores más citados, redes de colaboración, distribución geográfica de publicaciones, áreas de conocimiento, tipos de documentos y entidades financiadoras. El análisis incluyó documentos publicados entre 2015 y 2025, filtrados bajo criterios de alta relevancia e impacto científico. Los resultados evidencian un patrón de consolidación acelerada en la última década, con 70 publicaciones de alto impacto: 49% artículos científicos, 34% artículos de congreso, 15,7% revisiones bibliográficas y 1,4% cartas científicas. Se identificó un núcleo emergente de autores y países líderes, así como una marcada orientación hacia la sostenibilidad, la economía circular y la integración tecnológica. Estos hallazgos aportan una base de conocimiento interdisciplinar que conecta la arquitectura, la ingeniería, las ciencias ambientales y las ciencias sociales, con implicaciones prácticas para la planificación urbana y la gestión eficiente de los sistemas alimentarios en ciudades sostenibles.

    In the current context, urban centres in Latin America are facing fundamental challenges in their endeavour for Sustainable Development. The focus of this study is the meticulous assessment of the perception of urban sustainability within the Lurín District of Peru. It introduces a system based on urban sustainability indicators, derived from social surveys and implements this system through linear regression models to discern their interrelations. The objective of the research is to quantify and evaluate essential elements linked to the management of natural resources, air and water quality, the advancement of sustainable mobility, education and the well-being of urban residents. By delineating these mathematical and statistical correlations amongst variables pertinent to urban sustainability, this study provides a robust framework for quantitative decision-making in the urban sphere. A methodology for the development of univariable and multivariable models has been demonstrated. Amongst the most important findings, it has been discovered that the variable Environmental Education System (SEA) is perceived as the least important and even negligible within the multivariable models. However, we believe this effect occurs because the impacts of education are perceived in the long term. This article contributes significantly to the academic discourse by providing a more nuanced understanding of the social perception of urban sustainability and its influence on policy formulation and decision-making processes in Latin America.

    Heavy metals (HMs) in soil are a big threat to environmental and agricultural sustainability. This review discusses the development of the nanobioremediation paradigm (an approach combining nanotechnology and microbiological processes) for the treatment of HM toxicity. Recent advances in nanoparticle (NP)-based approaches to their ability to improve microbial detoxification methods, such as adsorption, redox transformation, and enzyme activation forms of microbial detoxification are discussed. Key findings suggest that many engineered NPs (e.g., zero-valent iron, biogenic metal oxides) can enhance HM immobilization efficiencies and contour microbial performances and functions of the soil microbiome. Still, there are areas of uncertainty regarding NP-microbe-soil interactions, long-term ecotoxicological effects, and applicability at the field level that are critical to be discussed. Future research directions are advised to focus on the eco-designed NPs, optimizing microbial consortia specific to the soil, and interdisciplinary frameworks linking the laboratory methods and materials to the real-world applications.
