dc.description.abstractLa deforestación resulta en cambios en la provisión de servicios ecosistémicos a escala global, regional y local. Servicios como la captura y el almacenamiento de carbono, la regulación climática y la atenuación de riesgos naturales como inundaciones son solo algunos de ellos. En Colombia la relación entre deforestación y la ocurrencia de eventos de emergencia de origen hidroclimático no ha sido estudiada a escala nacional y se propone que el porcentaje de deforestación tiene incidencia en la ocurrencia de eventos de emergencia relacionados con inundaciones, deslizamientos y sequías. Usando información de deforestación a nivel departamental y datos de eventos de emergencia de inundación, deslizamiento y sequía, se realizó un análisis espacial mediante un sistema de información geográfico y análisis de correlación entre el porcentaje de deforestación y la frecuencia de eventos de emergencia en tres periodos en el tiempo 2000-2005, 2005-2010 y 2010-2012. Los departamentos con mayor porcentaje de deforestación presentan alta frecuencia de eventos de origen hidroclimatológico, principalmente aquellos ubicados en la zona Andina y Caribe. Las variables de inundación y sequía presentaron una correlación positiva y significativa para el periodo de tiempo 2000 -2005 y de manera similar, para el periodo de tiempo 2005 -2010 las variables inundación, deslizamiento y sequía obtuvieron correlación positiva y significativa. En el caso contrario, para el periodo de tiempo 2010-2012 no se encontró ninguna correlación. En conclusión la pérdida de los bosques en el país puede estar reduciendo la prestación de importantes servicios ecosistémicos asociados a la regulación de inundaciones y sequías.spa

dc.description.abstractenglishThe impacts associated with deforestation include changes in ecosystem services at the global, regional and local levels. Capture and storage of carbon, climate regulation and mitigation of natural hazards, such as floods, are just some of the services that have been affected by deforestation.In Colombia the correlation between deforestation and the occurrence of emergency events originated by hydroclimatic conditions has not been studied at national level and therefore, this study address the relationship between the rate of deforestation and the occurrence of emergency events related to floods, landslides and droughts. Using information of deforestation at the departmental level and emergency event data, regarding floods, landslide, drought, a spatial analysis was executed by making use of a geographic information system. On the other hand, statistical analysis was performed in order to find a correlation between the percentage of deforestation and occurrence events frequency for three periods of time 2000-2005, 2005-2010 and 2010-2012. The results show that departments with the highest rate of deforestation have high frequency of hydroclimatological events, mainly those located in the Andean and Caribbean regions. On the other hand, the variables: flooding and drought had a significant positive correlation for the period 2000 -2005. Similarly, for the period 2005 -2010 variables: flooding, landslides and drought had positive and significant correlation. On the contrary, for the period 2010-2012 no correlation was found.eng
