  Pranata mangsa is a local knowledge based on a calendrical system utilized
historically by Javanese peasant farmers in conducting their agricultural
activities in cultivating plants and vegetation. It is also used by fishermen
to guide them not only in capturing fish and other aquatic animals but also in
predicting the type of seafood they might gather. Although the Javanese possess
and maintain their own calendrical system based on a combination of solar and
lunar calendars, pranata mangsa is solely based on the solar calendar and
passed on from one generation to the next verbally. Literature has confirmed
that by combining this local knowledge and scientific data, the Javanese
community has a better resilience in adapting to extreme hydrological events
due to global warming and climate change. In this comment, we provide remarks
on ethnic groups and the four sample cities in Java where the latter were
selected for the pranata mangsa study.
