ABSTRACT

The study was conducted during the years of 2019-2021 in Bagerhat (Fakirhat and Rampal upazilas) district of Bangladesh. In the studied upazilas two unions/two agricultural blocks were selected to carry out the study. The research was conducted in the study area and data was collected by two trained enumerators together with the researcher himself from 200 respondents via an interview schedule. Collected data from the respondents were analyzed in accordance with the objectives of the study. The coded data were put into the computer for statistical analyses. The SPSS computer program was used for analyzing the data. Statistical measurements such as number, percentage, range, average, standard deviation and ranking were used to describe the variables where ever applicable. The study critically securitized climate change hazards and revealed that “cyclone” ranked in the 1st position received the attention from 85% respondents, where as “salinity” in 2nd position, “fresh water shortage” in 3rd position and sedimentation in the last (12th) position. The major hazards occurred in coastal Bagerhat district mainly concentrated in four months of the year i.e. February to May. In a whole the agricultural damages were expressed in twenty different lines. Amongst the twenty identified and distinguished damages, “yield loss of rice” was the prime or major damage (supported by cent percent respondents). “Yield loss of vegetables” and “obliterate of fisheries” selected as the 2nd and 3rd top most damages in the coastal Bagerhat district of Bangladesh. Agricultural development is not possible without overcoming these selected issues, through which agricultural activities is under challenging in the coastal zones of Bangladesh. Due to adverse impacts of climate change the coastal agriculture is not in right line, continuously it is being changed. So it is needed to consider the negative changes while adjusting interventions in coastal agriculture.

Key words: Climate change, vulnerability, cropping pattern, coastal Bagerhat district.   

Introduction

 The coast of Bangladesh are highly resistant to climate change due to very low elevations, some terrain on the sea level, the topography of the deltaic region, the Bay of Bengal, socioeconomic profile and infrastructure renders the capacity to tackle the effects of climate related disasters (Agrawala et al., 2003). This area is more affected than any other regions of Bangladesh. They experience a variety of natural and man-made disaster events (Sea level rising-SLR, cyclones, storm surges, floods, droughts, saltwater intrusions, riverbank erosion, and landslides). The coastal areas of southwestern Bangladesh are already affected by rising temperatures, slow climatic stresses such as saltwater intrusions into agricultural soils, ground water, sudden storm surges and increased intensity such as floods, riverbank erosion impacting from cyclones, storm surges and climate change (Huq et al., 2015). The agricultural sector is also affected by rising temperatures and unpredictable rainfall in Bangladesh (Hossain et al., 2020; Wright et al., 2019). A temperature rise of 40° C has a serious impact on the production of edible grains, especially in wheat production. Though, carbon dioxide fertilization promotes the production of edible grains. As temperatures rise, rice and wheat production declines significantly by 28% and 68%, respectively (DAE, 2007). In this way the agricultural sector of Bangladesh is being badly affected due to climate change. Hence the main focus of the study was to find out the major agricultural impacts from climate changes to minimize the crop losses in coastal Bagerhat district of Bangladesh.
