Semillero de investigación: Análisis de vulnerabilidad ambiental de la ciudad de Tunja una herramienta para la gestión del riesgo

Abstract

The present work establishes the degree of vulnerability of the city of Tunja through the evaluation of 13 environmental indicators distributed in environmental exposure, environmental sensitivity and environmental adaptive capacity as fundamental axes of analysis of environmental vulnerability. The analysis of environmental vulnerability was developed based on a constructive-deterministic methodological combination through geographic processing and the application of surveys of environmental sensitivity and adaptive capacity to a population sample of 390 inhabitants of the city of Tunja and 20 officials of the local environmental and land-use institutions, respectively. The indicators were processed to obtain as products, vulnerability assessment matrices before the mentioned axes of analysis and the corresponding cartographic product. The development of the methodology gave as a result that three of the ten urban areas of the city present a HIGH value of environmental vulnerability, specifically, neighborhoods such as Mirador Escandinavo, Sierra and Ciudad Jardín are the most vulnerable, this due to a HIGH environmental exposure in indicators such as flooding and forest fires, a LOW environmental sensitivity in terms of the indicator corresponding to environmental knowledge and a LOW environmental adaptive capacity in indicators such as normative coverage and environmental education.
