    Territories historically lacking planning have been forced to implement contingency measures in various aspects of their ordering and development. Management plans are formulated focused more on the implementation of palliative and corrective measures, forgetting the efficiency of long-term, forward-looking exercises that properly address the territory. Seeking to respond to the transformation and loss of ecosystems, we must choose strategies that, together, result in qualified urban spaces as a response to the restructuring of green spaces. Several elements have an impact on the progressive deterioration of quality-of-life indexes and gradually degrade the socio-environmental conditions of spaces that become less and less inhabitable every day. This is when the absence of effective and disruptive interventions in the territory becomes evident, frequently resulting in phenomena associated with the deterioration of public health, the appearance of diseases usually linked to unhealthy lifestyles, the worsening of atmospheric conditions and the fast growth of settlements in an area with low support capacity. Besides, ground waterproofing, the emissions from mobile and industrial sources and the indiscriminate covering of natural water sources contribute to the generation of heat islands and the consequent negative effect on termic comfort. Based on a perceptive, experimental, deductive, contextual and normative analysis, this research project is developed based on a propositional diagnostic exercise with qualitative and quantitative aspects at the territorial level. This project identifies urban and environmental problems, with an emphasis on the significant lack of public spaces for recreation and human interactions at the municipal level, especially at the neighborhood scale. It is at this scale that the absence of green infrastructure becomes evident, one that actually contributes to ecosystem services and is properly articulated as the ecological backbone of the city, starting from the local level and reaching a more general scope. In this line, suitable tools are conceived for the construction of elements that favor good urban practices that are supported and welcomed by those who will make use of them. The evaluation of planning instruments resulted in an exercise that proposes the construction of a management model that makes it possible to develop a practical and effective tool for the transformation of streets currently devoted exclusively to vehicles into effective public spaces for recreation and encounters, with green infrastructure, soil recovery and tree cover that complement ecological connectivity. The goal is also to propose a replicable pilot for other cities with similar characteristics, contributing to the construction of the indicator of public space deficit and the adoption of effective green public space as the element of consolidation and assessment of the environmental and urban conditions of the territory.

    Proceso de ASC - CONTABILIDAD SOCIAL Y AMBIENTAL. FUNDAMENTACION TEORICA PARA EL CONTEXTO LOCAL
    (Universidad EAFIT, 2019) Ocampo-Salazar, Carmen; Garcia, Danny; Cardona-Hernández, Juan David; Universidad EAFIT
    The project's aim is to formulate the theoretical structure of a social and environmental accounting framework. This research is an alternative proposal to traditional accounting, which has its foundations and technological developments in a financial perspective, and is therefore reductionist and unable to inform and reflect other complex dynamics of organizations with social and environmental structures. The framework proposes to take social and environmental categories as central in the local context and framed within the Sustainable Development Goals (SDGs), considering research focused on human needs from the perspectives of Professors Max-Neef, Elizalde, and Hopenhayn (2010). Here, interdisciplinary work is necessary. The methodology involves strategies such as documentary research and discussion groups.
