Location of studied villages in Barpeta and Paka-Betbari blocks of Barpeta district of Assam
by
beels
(ARSAC
1990
) and some important of
them are Ghandhi, Baramara, Hahsara, Sigmara,
Morachaulkhowa, Chichajan, Baira, Boha,
Paghda, Korila, Raumari, Uri, Chagalsari,
Halaldai, Golibandha, Finga and Bara.
Twelve villages have been selected for the
present study, viz., Chagalsari, Niz Barala,
Galibandha, Nagaon, Baragdia, Barsimla,
Nasatra, Aratari, Kaljhar, Fularguri, Kathalartari
and Bamunbari (Fig.
19.1
). Household is the
main unit of observation and stratifi ed random
sampling is used to extract the representative
nature of the population. Structured question-
naires are framed to collect the fi eld data. Besides,
secondary data were collected from all the line
departments. Physical, chemical and biological
aspects of the wetlands were assessed to know
their impacts on fi sh population. For the purpose,
Ghandhi, Sigmara, Bara, Korila, Halaldai,
Raumari, Baira, Boha, Paghda and Finga wet-
lands are considered.
Results and Discussions
Impact of Flood
The water is the vital ingredients for the survival of
human being, but sometimes it may cause woe to
the human life not due to insuffi cient water but due
to abundant water which in turn causes the natural
disaster like fl oods (Bhowmick
1999
). The district
of Barpeta is situated at the foothills of the
Himalaya. Every year the district experiences a
huge amount of losses due to devastating fl ood
caused by the river Beki and Manas and its tributar-
ies along with the river Brahmaputra. The problem
of fl ood is perennial in the area, and the solution is
diffi cult due to complex and devastating nature of
the rivers during monsoon period. In this part of the
study, socioeconomic impact of fl ood is taken into
consideration in the two studied blocks and tried to
fi nd out the adaptability of the local people.
