Despite that waterfront tourism tends to be more favorable for
the economic development and environmental protection of the
region, it does not outperform marine transportation on every
select dimension of assessment in the study. In other words,
tradeoffs may still merit some co-existence of both sectors. With
regard to SO
emission and freshwater consumption, waterfront
tourism incurs even greater environmental footprints for every
unit of gross output contributed to the region. Besides, the
discharges of COD and TP induced by waterfront tourism at the
unit level are comparable to those induced by marine transportation
(less than 10% of difference). Thus, the recommendation of
waterfront tourism as principal functional use does not mean to
