Abstract:
Bangladesh is a developing country and its economy depends largely on agriculture but the
economic sector is most vulnerable to climate change and variability. This survey study is
intended to know the nature of hazards, identify and analyze the adaptation options due to
climate change in Shyamnagar upazila of Satkhira district. Data were collected from the
farmers of selected five villages (Ramjannagar, Padmapukur, Munshiganj, Kashimari and
Koikhali) of Shyamnagar Upazila of Satkhira district during August, 2016 to December,
2016 by open questionnaire process. The sample size of the study was 100 farmers and
drawn from a population size of 650 using proportionate random sampling technique. Data
were processed and analyzed using excel-2007 and SPSS-16. The study revealed that the
intensity of salinity has increased and 91% of the respondents observed that some crops
damaged than that of past and some other hazards (flood, cyclone, rainfall etc.) are posing
new threat by changing their nature. About 86% of the respondents perceived and adapted
to climate change. In the study area there were different adaptation options viz. sorjan
method, crop rotation, saline tolerant varieties, crop diversification, mini pond, adjusting
planting time etc. introduced for agricultural activities and also enhancing agricultural
production, improve soil health. In the study area farmers faced some problems those
problems are ranked using Problem Confrontation Index (PCI), there “lack of available
water” (PCI-291) ranked 1
st
“shortage of cultivable land” (PCI-287) 2
nd
and “unpredicted
weather” (PCI-284) 3
rd
respectively. The adaptation options were measured by applying
Adaptation Strategy Index (ASI) method, there “sorjan method”(ASI-287) ranked first,
“Crop rotation”(ASI-242) 2
nd
and “saline tolerant varieties” (ASI-232) 3
which are the
attractive adaptation options in the study area. About 86% of the respondents followed
Boro rice-Vegetables-T.aman cropping pattern in Shyamnagar upazila. There are some
barriers of adaptation measures like lack of irrigation facilities (94%), lack of knowledge
(90%) and poor soils (90%) on the top. For water harvesting adaptation options farmers
benefited by digging mini-pond in crop field, water reserve in narrow canal in crop field.
DAE, CDMP, FAO and different NGOs are doing the jobs. However, due to introduction
of innovated adaptation tecniques the said threats have been mitigated to a greater extent.
And, this has become possible only for the coordinated support from the government,
development partner (NGOs, WB, FAO etc.) and local people.
