• 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

Green City
Trujillo, Veronica – Green growth in urban coastal zones
Land Uses
• Urban design must contemplate the coast as
prime real estate (aesthetic and functional value)
• Compatible Mixed Uses
– Housing, Commerce
– Densification + Economies of Scale
• Sea Level Rise → Shoreline Modification
– Preservation of environmental values
• Establishment of urban protection areas (e.g.
mangroves)
Transportation
Linear Park of Cartagena de Indias
• Coastal Zones for people, not cars
→High scenic value
– Priority of non-motorized forms of
transport
– Construction of adequate
infrastructure: linear parks and
boardwalks
• Connectivity of littoral areas with
other parts of the city
– Public Transport
– Areas determined for Parking
– Tramways
• Aquatic Transport for commuting
Boardwalk of San Andrés Island
Water resources
managment
• Efficient stormwater management systems– Resilience to natural disasters
– Informal Settlements in High Risk Areas
– Coastal area pollution is a transboundary issue, requiring
concerted efforts by all coastal cities.
• Appropriate urban infrastructure – potable water
networks and sewage systems (from the source to
its final destination)
– Wastewater for reutilization-reduce pollution, energy
source
– Increase of human well being (reduction of
Morbimortality), favors the environment

Conclusions
• Coastal cities must learn to implement both green growth and
integrated coastal zone management (ICZM) strategies, thus
environmental, social, economic and governance aspects can be
incorporated to a resilient city.
• ICZM + Green growth require strong community participation
from plan conception to implementation. 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!
