System dynamics

4. System dynamics applications
• System Dynamics (SD) has been used a lot in
coastal area, e.g.
– for improving value of ecosystem services in
Shinduri coastal area in South Korea (You et al.,
2018)
– for managing sustainable tourism using a decision
support system in Cijin, Kaohsiung, Taiwan (Tan et
al., 2018)

– for predicting the sustainablity of tuna ranching
industry in Mexico (Robadue & del Moral
Simanek, 2007)
– for simulating forward scenario of sustainability
landscape in Cimandiri Estuary, West Java,
Indonesia (Supriatna et al., 2016)
– for assessing of the impacts of storm damage on
coastal communities in Chabahar Bay, Iran
(Moradi et al., 2020)

– for observing appropriate technology application
in Aboriginal New South Wales coastal
community, Australia (Jokhu & Kutay, 2020)
– for analysing the eco-aquaculture system of integra-
ted aquaculture park in Malaysia (Isa et al., 2020)
– for conceptualizing social-ecological system dyna-
mics in the Bangladesh delta (Hossain et al., 2020)
– for simulating of a port–city green cooperative
development, Shanghai Port, China (Li et al., 2019)

Model

9. Model
• There five main nodes
– Green Technology
– Population
– Interstate Infrastructure / Industry
– Port-driven GDP
– Urban GDP
• The last two are the central nodes, while the
first three supporting nodes

23. Summaries (cont.)
• It shows that implementation of Green Tech-
nology policy give some benefits than the con-
ventional one, such as higher GDP for port and
the city nearby but with relatively the same
population
• These results show a promising future of the
development of a green port for Patimbang
