Flooding events pose an immediate threat to the population in
terms of economic loss and risk of injury of death. During the
survey, it is observed that some new houses in existing villages
have a slightly elevated foundation to protect against (pluvial)
floods (Fig. 3B). We have inquired the interviewees about the
prevalence and origins of these floods. 29% of all respondents have
indicated that they have been affected by flood (Fig. 7A), of which
11% (n 1⁄4 3) monthly, 67% annually, 22% once per decade. 37% of the
people that farm a crop have ever been affected by floods. When
asked about the origin of the floodwater, the majority of re-
spondents (67%) have answered from pluvial events, while 22%
answered from the sea through storm surges, and 11% (n 1⁄4 3)
answered that the flood originated from the river.
