This article discusses on the sustainability of daily mobility from the analysis of inhabitant’s practices of two popular peripheral areas of the city of Lima. It provides an analysis of experiences with the use of «sustainable» modes (walking, cycling and public transport) and «unsustainable» modes. A number of obstacles related to distance, slope or insecurity are highlighted, as well as their influence on mobility strategies and the choice of modes. The characteristics of the environment and the mobility needs in the popular peripheries do not facilitate the use of so-called «sustainable» modes, compared to «unsustainable» modes such as mototaxis, taxis or colectivos, even combis, which greatly ease the mobility of people despite constraints in terms of security and cost.

El trabajo analiza la vulnerabilidad de la población expuesta al riesgo de lahares del volcán Cotopaxi en el Valle de los Chillos (Quito, Ecuador). Propone una cuantificación, caracterización y análisis del nivel de exposición de la población, apoyándose sobre herramientas cartográficas, al mismo tiempo que busca responder a las necesidades locales a fin de aplicar una lectura geográfica del riesgo. Busca de esta manera identificar los criterios pertinentes, los mecanismos de organización y las particularidades a analizar con el fin de suministrar elementos pertinentes y útiles a la gestión del riesgo. Propone entender el proceso de construcción del riesgo, y como este genera la vulnerabilidad. Pone en evidencia los aspectos de negociación del riesgo, así como las diferentes vulnerabilidades de la población residente, así que de la población “de día”, que se encue...
