A Socio-Environmental Dynamic Model for Assessing Urban Heat Island Influence on Particulate Matter Concentrations
Urban growth and climate change intensify urban heat islands (UHIs), altering atmospheric stability and promoting the accumulation of particulate matter ≤ 10 μm (PM10) and particulate matter ≤ 2.5 μm (PM2.5), particularly in high-altitude megacities. However, there remains a scarcity of integrated dynamic models capable of representing these interactions at the intra-urban scale. This study develops a socio-environmental dynamic model to evaluate…
Dynamic Simulation Model for Urban Street Sweeping
Urban street sweeping infrastructure plays a critical role in municipal solid waste management by mitigating particulate matter resuspension and preventing contaminant mobilization into water bodies, thereby supporting public health and environmental sustainability. The primary objective of this study is to develop a dynamic evaluation model for urban street sweeping services in four localities of Bogotá, Colombia. Operating system variables are …
Systematic Review of Dimensions and Indicators in Sustainable and Smart Cities
Accelerated urbanization challenges cities globally. Ensuring good quality of life and environmental protection requires innovative, data-driven solutions. Sustainable and smart cities (SSCs) offer a promising response, but effective implementation depends on selecting and using appropriate dimensions and indicators. The main objective of this article is to present a systematic review within the framework of SSCs to study trends in the use of dim…
Tendencias metodológicas para la inclusión social de tecnologías apropiadas en zonas rurales
Este artículo tiene por objetivo estudiar las tendencias metodológicas a nivel mundialde tecnologías apropiadas (TA) desarrolladas en zonas rurales con inclusión social. Se realiza una revisión sistemática en bases de datos científicas. Se identifican las principales metodologías (cualitativas, cuantitativas y mixtas), herramientas y enfoques en procesos rurales con TA. Se detectan también los principales factores (social, técnico, económico, amb…
Percepciones sobre fenómenos volcánicos
La teoría cultural del riesgo establece que cada sociedad construye, a partir de diferentes referentes históricos y simbólicos, una percepción diferencial sobre los riesgos que eventualmente los pueden afectar. De esta manera se genera todo un edificio simbólico alrededor de las amenazas circundantes, las propias vulnerabilidades y la generación de espacios denominados "de seguridad relativa", aspectos de importancia que se relacionan con posible…
