Cartagena de Indias in Colombia CRITICAL AREA NCAP: Colombia 2005-2008
Caribbean colombian and SLR 55% population Cartagena Barranquilla Santa Marta Barranquilla Santa Marta 4.752.137 inhabitants * 11% nacional total 85% urban area 15% rural area Growth rate 4.1% ** Cartagena Area 26.898 km2 (2.4% total national)* 81 munipalities 64.35% people with NBI (unsatisfied basic needs Index) ++ * 26 inhabitants/km 2 ** 2 % National Poblational Growth Rate ++ exceeds the national average by a factor of 1.7
Objective To design of a dynamic visualization tool that enables easy identification of the most vulnerable areas of the city, using biophysical and socioeconomic factors, projecting the results of the analysis for future climate scenarios 2019 and 2040.

Conclusions and future work This tool may enable local authorities to identify high-risk areas in order to design and implement studies and investments needed to reduce potential risks and impacts of SLR in climate risk management and associated planning tools. Use of these outcomes and local results as lessons learned in land use planning instruments and policies, such as Territorial Climate Change Adaptation Plan and National Development Plan and National Climate Change Adaptation Plan.
Conclusions and future work Implementation of GIS and visualization and mapping tools to support the risk management and territorial planning, allows decision makers (public and private sector), to understand the use of these techniques to analyze and model coastal vulnerability to climate change scenarios and for inclusion in planning economic, social and environmental adaptation measures. If used as web tools (such as Geovisor and CLIMARES webpage services), it may facilitate consultation by different stakeholders and directly support decision-making process in sectors affected by climate change effects. Next step: Decision Support System provides the necessary elements for selecting among several possible alternatives to execute an action and serves the management, operations, and planning levels of an organization and help to make decisions.
