| Abstract: | Folk people of Tripura, a small state of Northeast India, rely on their own traditional knowledge
of phenological indicators for predicting the weather, to help plan their
agroforestry activities and for disaster prevention. One such prediction
relates to the phenology of Nyctanthes
arbor-tristis L., night-flowering jasmine, which helps them to forecast the
onset of heavy rainfall. During 2007-2009, a comprehensive study was initiated to
document the predictive accuracy of this indicator, through conversations and
interviews with village members, observation and reviewing the older
literature. The researchers found that the flowering of Nyctanthes arbor-tristis is a good indicator of weather lore for
the prediction of both short- and long-range precipitation. The information about the prediction of rainfall
by observing the flowering phenology was recorded through the interview with
village elders. The researchers use interview schedule while interacting with
elders. Several small groups of knowledge holders including elder men and women
(as focus group) were selected randomly from a wider population of study areas
and sampled. A questionnaire was also prepared for knowledge gathering through
open conversation and discussion. Prior Informed Consent (PIC) was taken from the knowledge providers time to
time. |
