. No incidences of landslides and flash floods in the community
have been reported. However, the city was struck by two
strong typhoons, Sendong and Pablo, on December 16, 2011 and
December 3 2012, respectively. Additionally, approximately 77%
of the interviewed fishers associate the difficulty in catching tuna
with high temperatures because tuna feed deeper during warm
days. An increase in temperature will cause a stronger thermocline
that limits water mixing between cold deeper waters and warm
shallower waters, which in turn causes a decline in primary productivity
(Gribbin, 1988; Papua New Guinea and Pacific Islands Country
Unit and the World Bank, 2000).
