Observing past human activities and their influences on the
coastal region is an important part of the research on climate
change and human adaptation. The traditional coastal management
practices also provide an enlightenment for modern coastal management.
In the future coastal management and adaptation, there is
a need to avoid monopoly in coastal development, and avoid
aggravating of stakeholders’ conflicts; the policies should be update
and adjusted in real time, to cope with the coastal change and
social-economic conditions. It is important to maintain the dynamic
balance between the coastal social-economic activities and
the natural environment changes. In general, although the monopoly
management policies were beneficial to the sea salt industry
over the deltaic region during the 16e19th centuries, they
became unsustainable under the condition of rapid population
growth. Timely adjustment according to local conditions would be
a positive approach to improve the land use efficiency, and to cope
with the new humaneland relationships.
