11 th International Symposium for GIS and Computer Cartography for Coastal Zones Managementmarine and coastal zones in Colombia) and other external sources (CARDIQUE, 2007; University ofCartagena-Mayor of Cartagena, 2010). The information of the study area was structured andgeographically referenced (using the MAGNA-SIRGAS official datum for Colombia) and at anoperational scale of 1:50,000. The methodology for structuring information and the further analysis,mapping generation, implementation and publication of Geovisor (http://gis.invemar.org.co/cdkn/) onCLIMARES webpage (http://cambioclimatico.invemar.org.co/), was conducted in accordance with thestandards of INVEMAR’s Information Systems Lab (LabSIS).One of the outcomes of this research is a map that shows the index of vulnerability to climate changein Cartagena de Indias and projections of future scenarios for 2019 and 2040. Figure 1 shows the‘pessimistic scenario’ – with most vulnerable areas to the impacts of climate change, given their exposureto coastal erosion, beach loss, decline in fisheries and flooding by SLR and the sensitivity given theirsocioeconomic conditions, like inadequate public services and infrastructure type. Geovisor helpsdecision makers modelling and visualizing scenarios based on different data, according to users’ interests(INVEMAR, 2012). This abstract shows a part of the project, it focuses on the importance ofvisualization techniques but not going deep in the analyses of affected areas or differences betweenscenarios displayed in Figure 1.Figure 1. Cartagena socioeconomic vulnerability to climate change scenarios with moderate sea-level rise in2019 (left) and high sea-level rise 2040 (right) (INVEMAR, 2012).The use of this tool may enable local authorities to identify high-risk areas in order to design andimplement studies and investments needed to reduce potential risks and impacts of SLR in climate riskmanagement and associated planning tools. Another benefit may be the use of these outcomes and localresults as ‘lessons learned’ in landuse planning instruments and policies, such as Territorial ClimateChange Adaptation Plan and National Development Plan and National Climate Change Adaptation Plan.Implementation of GIS and visualization and mapping tools to support the risk management andterritorial planning, allows decision makers (public and private sector), to understand the use of thesetechniques to analyze and model coastal vulnerability to climate change scenarios and for inclusion inplanning economic, social and environmental adaptation measures.
