    Environmental protection zones priorization for the decision making support
    (Corporación Universitaria Lasallista, 2013-10-26) Builes Jaramillo, Luis Alejandro; Lotero Vélez, Laura; Arroyave Rojas, Joan Amir
    Introduction. Air quality assessment deal with emission, concentration levels and definition of polluted areas, the results are often related with command and control regulations or restriction to transportation and industrial activities. This kind of approaches gives to environmental and territorial planners areas for special management and use. Objectives. Facilitate the priorization of those polluted areas in terms of future interventions to decision makers, integrating public health and demographic indicators to a previous planning exercise through, an Analytic Hierarchy Process (AHP) approach. Materials and methods. With an AHP developed via surveys for territorial and environmental planning experts, it was possible to define the importance weight and relevance of new indicators in the decision making exercise of prioritization of polluted areas in Medellin. The indicators were chosen from public databases of demographic and public health information and one of them (demographic) with a prospective time frame. Results. Experts in territorial planning tends to give more importance to health indicators for the prioritization of intervention in polluted areas, while the inclusion of a prospective indicator was useful in the definition of which of the areas should be the first or the most critical for intervention. The results also show that experts seem to have problems in structuring their decisions presenting some inconsistencies in their answers. Conclusion. We present clear cut results showing that the inclusion of new variables, especially those dealing with prospective information in previous air quality planning exercise is useful for the strategic decision making process.

    La gestión socio-ambiental y el recurso hídrico
    (Corporación Universitaria Lasallista, 2012-08-30) Arroyave Rojas, Joan Amir; Builes Jaramillo, Luis Alejandro; Rodríguez Gaviria, Edna Margarita
    This paper is a reflection about the way human beings have established their relationship with the environment and how it has brought difficulties in the environmental management. It emphasizes on the planning and the management of water resources, making a general review of the advances in the regulation associated to water that has impacted the management. Finally, it proposes a discussion about a change of the paradigm and of the social and the environmental cultures favoring a better social/environmental management of water resources, procuring its sustainability at all of the different scales.

    Modelo para la estimación de emisiones vehiculares como herramienta para la gestión ambiental institucional
    (Corporación Universitaria Lasallista, 2015-08-03) Valencia Arroyave, Daniela; Muñoz Duque, Michelle Andrea; Ramírez Muñoz, Alejandra; Builes Jaramillo, Luis Alejandro; Hoyos Restrepo, Carlos Arturo
    Introduction. This article introduces a model to estimate emissions produced by work and study commuting at an institutional level, along with an application case at Institución Universitaria Colegio Mayor de Antioquia. Objective. Develop a methodology based on the simplified emissions estimation model (SEEM), which uses the emission factors developed in Bogotá and that are available on the international model of the International Vehicle Emissions (IVE) database. The primary information was collected by the use of surveys developed by the institutional community. Those surveys included questions about the characteristics of the vehicles used by students, professors and administration staff for their commuting from and to the institution. Results. With the results obtained thanks to the implementation of the methodology developed, it was concluded that the institution contributes with less than 0,025 % of the total emissions in the Aburrá Valley. Several scenarios are proposed to control the atmosphere pollution produced by commuting from and to the institution, by means of rationalizing the use of private cars, thus obtaining up to 29 % in reductions of the criteria pollutants: MP, CO, VOC, SO2 and NOx. Conclusions.The methodology is easy to apply and it is also easy to transfer it to other institutions or companies with different sizes and traffic flows.
