Mixing Integrated Coastal Zone Management and Green Growth in Colombia: A recipe to resilient coastal cities? Verónica Trujillo-Gedeon Former visiting Research Fellow, Global Development Partnership Center, Korea Research Institute for Human Settlements, Colombia Javier Mouthon-Bello Associate Professor, Universidad de Cartagena (Colombia) June 1st, 2013 Coastal cities in Colombia Caribbean Sea Pacific Ocean 1937 km of coast line Three major coastal cities* 1576 km of coast line Two major coastal cities* • Cartagena • Santa Marta • Riohacha • • 979 000 inhabitants 470 000 inhabitants 241 000 inhabitants Buenaventura 384 000 inhabitants Tumaco 191 000 inhabitants * 2013 Estimated population by DANE (Colombia) Coastal cities in Colombia Jaime Correa –2009 Cartagena de Indias - World Heritage City 979.000 inhabitants Climate change impacts Cartagena de Indias, Flooding event 2010 Sea level rise – storm surges Drought Coastal erosion Ecosystem loss Invemar y Alcaldía de Cartagena Climate change impacts se are usually surrounded by mangrove areas.

Jaime Correa –2011 Learning from the past looking to the future Main ingredients ICZM Dynamic process that promote sustainable development in coastal zones Green City Preserve and enhance environmental qualities Resilient Coastal City Jaime Correa –2009 Integrated Coastal Zone Management (ICZM) C Invemar, 2009 • Dynamic, continuous and interactive process designed to promote sustainable development in coastal areas through policies, strategies and sectorial plans in space and time, taking into account the marine and terrestrial components of the littoral (Barrangán, et al., 2008) Stages for an ICZM plan 1 • Problem identification and evaluation 2 • Characterization and assessment 3 • Plan formulation and adoption 4 5 • Plan implementation • Evaluation and review INVEMAR, 2003 Problem identification and Evaluation 1.

Stakeholders should share their experiences and responsibilities with local and national government. • ICZM experiences improves national policies, and results in a better understanding of the capacities and needs of local level. Together we build a resilient city Happy Bday Cartagena! Alcaldía de Cartagena, 2011
