Estrategia de articulación de instrumentos de gestión del ordenamiento territorial, mecanismos de financiación e intervenciones integrales del territorio(Universidad EAFIT, 2017) Salazar Ramírez, Esteban; García Bocanegra, Juan CarlosÍtem Concentración de la propiedad de la tierra y producto agrícola en Antioquia. 1995-2004(Universidad EAFIT, 25/04/2008) Mora, Tatiana Maritza; Muñoz, Juan Carlos; Universidad de Antioquia; Universidad de los AndesÍtem Constitucion i ordenanzas de la provincia de Tundama, espedidas por la lejislatura en sus sesiones ordinarias i extraordinarias de 1854 i 1855(Bogotá : Imprenta Echeverría Hermanos, 1855, 1855) Lejislatura Provincial de TundamaÍtem Derechos de propiedad y externalidades en las llanuras de inundación de la Cuenca Alta del rio Aburrá (2000-2015): un caso sobre detonantes de tensiones y conflictos socio ambientales(Universidad EAFIT, 2015) Soto Ángel, Francisco Javier; Peláez Arango, Juan RafaelLa vulneración de instituciones formales como las Normas de usos del suelo, las cuales delimitan los derechos de propiedad, y los instrumentos de planificación como el plan BIO2030, POMCA y PBOT municipales, ha sido fuente de generación de externalidades negativas que desatan a su vez tensiones y conflictos socio ambientales entre actores públicos, privados y comunitarios asentados en la cuenca -- Con la ocupación irregular de las áreas de retiro y llanuras de inundación –ARLLIRA- en la cuenca alta del río Aburrá, para fines industriales, comerciales y vivienda desapareció la función de regulación natural de la cantidad y velocidad del caudal del río; entendida esta, como un servicio público “puro” de carácter ambiental del que ninguna persona o colectivo puede ser excluido o rivalizar por esteÍtem Development of structural debris flow fragility curves (debris flow buildings resistance) using momentum flux rate as a hazard parameter(Elsevier B.V., 2018-05-18) Prieto, Jorge Alonso; Journeay, Murray; Acevedo A.B.; Arbelaez, Juan; Ulmi, Malaika; Prieto, Jorge Alonso; Journeay, Murray; Acevedo A.B.; Arbelaez, Juan; Ulmi, Malaika; Universidad EAFIT. Departamento de Ingeniería de Producción; Materiales de IngenieríaSocietal risks associated with debris flow hazards are significant and likely to escalate due to global population growth trends and the compounding effects of climate change. Quantitative risk assessment methods (QRA) provide a means of anticipating the likely impacts and consequences of settlement in areas susceptible to landslide activity and are increasingly being used to inform land use decisions that seek to increase disaster resilience through mitigation and/or adaptation. Current QRA methods for debris flow hazards are based primarily on empirical vulnerability functions that relate hazard intensity (depth, velocity, etc.) to expected levels of loss for a given asset of concern, i.e. most of current methods are dedicated to loss-intensity relations. Though grounded in observed cause-effect relationships, empirical vulnerability functions are not designed to predict the capacity of a building to withstand the physical impacts of a debris flow event, or the related uncertainties associated with modelling building performance as a function of variable debris flow parameters. This paper describes a methodology for developing functions that relate hazard intensity to probability of structural damage, i.e., fragility functions, rather than vulnerability functions, based on the combined hydrodynamic forces of a debris flow event (hazard level) and the inherent structural resistance of building typologies that are common in rural mountainous settings (building performance). Hazard level includes a hydrodynamic force variable (FDF), which accounts for the combined effects of debris flow depth and velocity, i.e. momentum flux (hv2), material density (?) and related flow characteristics including drag (Cd) and impact coefficient (Kd). Building performance is measured in terms of yield strength (Ay), ultimate lateral capacity (AU) and weight to breadth ratios (W/B) defined for a portfolio building types that are common in mountain settlements. Collectively, these model parameters are combined using probabilistic methods to produce building-specific fragility functions that describe the probability of reaching or exceeding successive thresholds of structural damage over a range of hazard intensity values, expressed in terms of momentum flux. Validation of the proposed fragility model is based on a comparison between model outputs and observed cause-effect relationships for recent debris flow events in South Korea and in Colombia. Debris flow impact momentum fluxes, capable of resulting in complete damage to unreinforced masonry buildings (URM) in those regions are estimated to be on the order of 24 m3/s2, consistent with field-based observations. Results of our study offer additional capabilities for assessing risks associated with urban growth and development in areas exposed to debris flow hazards. © 2018 Elsevier B.V.Ítem Development of structural debris flow fragility curves (debris flow buildings resistance) using momentum flux rate as a hazard parameter(Elsevier B.V., 2018-05-18) Prieto, Jorge Alonso; Journeay, Murray; Acevedo A.B.; Arbelaez, Juan; Ulmi, Malaika; Mecánica AplicadaSocietal risks associated with debris flow hazards are significant and likely to escalate due to global population growth trends and the compounding effects of climate change.

Revisión Caso Cali, Colombia, periodo 2006-2016(Universidad EAFIT, 2017) Pretel Meneses, Álvaro José; Garza Puentes, Néstor FernandoThe article analyzes the effects of mass transit systems and buildable capital gains in Latin American cities, inspiring in a comprehensive review of land use theoretical literature and agglomeration economics -- After the theoretical discussion identify its implications and possible outputs, and make´s a study case over the city of Cali and it´s Mass Transportation System -MIO, studying how to generate additional buildable areas and incomes trough value capture instruments, to finance public worksÍtem Escenarios del sector agropecuario : aplicaciones para Colombia a través de un modelo de Equilibrio General Computable (CGE)(Universidad EAFIT, 2019) Gutiérrez López, Natalia; Ceballos Meneses, José Andrés; Hurtado Rendón, Álvaro Arturo; Botero García, Jesús AlonsoÍtem Estrategia integral de Codesarrollo entre contextos formales e informales(Universidad EAFIT, 2018) Arango Castaño, Janeth; Cifuentes Cuéllar, Andrea Viviana; García Bocanegra, Juan CarlosLatin America, one of the most urbanized regions of the world, is also one of the most socially and economically inequitable; consequently, the main challenge for Latin American cities for the coming years will be to overcome urban segregation and ensure the right to the city of all its inhabitants -- A first step to achieve this is to understand the patterns of urban segregation and identify the possible territories of opportunity where there is a potential for overcoming inequality -- This thesis recognizes as territory of opportunity the periphery lands of Colombian cities where informal settlements commonly converge with delimited areas for new formal developments (partial plans) -- In these territories of intermediate scale, a change in the traditional patterns of urban segregation begins to be perceived; the distance between rich and poor is reduced and, therefore, tensions and conflicts between formal and informal contexts increase -- This phenomenon, called exclusionary socio-spatial segregation, occurs in cities such as Bogotá, Medellin and Pereira -- It is necessary to propose a change in the way of planning Colombian cities and, specifically, the periphery territories where formal and informal contexts converge -- In this sense, this research project proposes a comprehensive co-development strategy that seeks to overcome the negative preconceptions and prejudices that exist towards informal settlements, recognizing opportunities for articulation with the formal city within the framework of a new paradigm in which it is possible to generate co-benefits between formality and informality -- To design the strategy, a research methodology was developed based on the analysis of a case study: The Partial Plan Parque Temático and the informal settlement of the Banca del Ferrocarril in the city of Pereira, Colombia -- From this study it was determined that the innovation in the implementation of land planning, management and financing instruments, in partial plans located in the periphery and including informal settlements, is a possible means to overcome the exclusionary socio-spatial segregation and guarantee the right to the city of the inhabitants -- The comprehensive co-development strategy structures this innovation based on a sustainable urban planning approach according to which the formal and informal actors of the territory are jointly responsible for the construction of a common future, where they can consolidate their ways of living, staying and developing socially (social sustainability), can have an economic security according to their interests and motivations (economic sustainability), and assume together the responsibility of taking care of their physical space and their natural environment (urban environmental sustainability)Ítem Guía socio-ambiental para las obras de construcción de vivienda en la ciudad de Armenia(Universidad EAFIT, 2017) Nivia Montenegro, Luz Stella; Monsalve Durango, Elkin AníbalArmenia es una ciudad con una riqueza natural y ambiental, reflejada en las 54 quebradas que conforman 18 microcuencas que recorren el territorio urbano hasta drenar a los ríos Quindío, Espejo y la Quebrada Cristales -- Estos espacios naturales incluyen fauna y flora que generan una fortaleza y riqueza ambiental en una región declarada por la Unesco en el año 2011 como paisaje cultural cafetero -- El paisaje y extenso verde de la ciudad, se ve en peligro debido al desarrollo de la construcción por la creciente demanda de vivienda en la zona -- El incremento de las actividades de construcción ha generado la expansión del territorio, la densificación edificatoria, la intensificación del uso del suelo, la demanda de recursos naturales, un impacto en los servicios públicos por las exigencias de expansión, el incremento de residuos sólidos, la contaminación del suelo, aire, agua e impacto en las microcuencas urbanas y traumatismos en la población del área de influencia -- La actividad de la construcción no sigue lineamientos claros respecto al componente ambiental y la realidad natural de la ciudad -- Algunos de estos actores, sin analizar el impacto socio – ambiental de los proyectos y sin conocer plenamente las etapas de la construcción e influencia en el entorno no desarrollan una óptima planificación de las actividades que se ejecutan antes y durante el proyecto, al igual que la implementación de un plan o programa de manejo ambiental para proceder de manera ágil y rápida en la mitigación del impacto en el medio ambiente y la población del área de influencia -- El estudio permite establecer como son las dinámicas de construcción en la ciudad de Armenia y su relación con el medio ambiente; además de proponer unas estrategias en una guía ambiental como referente en la toma de decisiones de los diferentes actores (constructores y comunidad en general)Ítem Implementación de los Sistemas de Información Geográfico, para la zonificación geotécnica como herramienta para la gestión de los georecursos, en una Pequeña Central Hidroeléctrica.

Departamento de Geología; Michel Hermelin Arbaux (hermelin@eafit.edu.co); Geología Ambiental e Ingeniería Sísmica (GIGAI)This paper intents a brief description of the evolution that characterised natural risk prevention in the area surrounding the city of Medellin, Colombia, called the Aburra Valley. Both the lithological and structural composition of the Valle and its topographic and climatic conditions contribute to the abundance of destructive natural phenomena as earthquakes, slope movements, flash floods and, in a lower proportion, to floods. The population increase, which reaches now 3.5 millions inhabitants and the frequent occupation of sites exposed to natural hazards have resulted in numerous disasters. At present two entities called SIMPAD and DAPARD work on risk prevention, on city and department scale respectively. The amount of knowledge about physical environment is considered to be insufficient, together with regulations which should direct land use in accordance to restrictions related to natural hazards. Several seminars on this topic have already been carried out and the organisers of the present one, destined to commemorate the twentieth anniversary of the Villa Tina disaster, should make the decision to meet each two years. Furthermore, the creation of a permanent commission dedicated to study past events, to foster information broadcasting and to seek a better knowledge of the Aburra Valley, should be considered.Ítem Zonificación de la aptitud geológica en el margen occidental del área rural de Itagüí (Antioquia): veredas La María, Los Olivares, Loma de los Zuleta y El Pedregal(2018) Franco Gómez, Juan Pablo; Caballero Acosta, José Humberto
