The Chalan Beel is situated between 24.35° to 24.70°N and between 89.10° to 89.35°E. Historically, the Beel was spread over the 18 Upazila (sub-districts) of six districts, including Rajshahi (Paba, Bagmara, and Mohonpur), Pabna (Chatmohor, Vangura, and Faridpur), Sirajgonj (Tarash, Ullapara, Raigonj, and Shahjadpur), Natore (Sadar, Singra, Gurdaspur, and Baraigram), Naogaon (Manda, Raninagar and Atrai), and Bogra (Nandigram). It presently spreads over only 10 Upazilas including Singra, Gurdaspur, Boraigram, Chatmohar, Bhangura, Faridpur, Shahjadpur, Ullapara, Tarash, and Raigonj of three districts of Natore, Pabna, and Sirajgonj.At the onset of the research, the total numbers of households within 500 meters from the boundary of the Beel were determined by a rapid survey. Households were then selected randomly from each settlement so that 20% of households formed samples for the interview. In total, 206 households were surveyed in nine small villages in three unions of Tarash Upazila of Sirajganj district. The nine selected villages were Nado syedpur, South Sampur, Ambaria, Hamkuria, Dobila, Ghor gram of Magura Binod Union and Kamarson, Makorson, and Kondoil villages of Soguna Union. Usually, household heads were interviewed but, in their absence, any member willing to participate was interviewed. A quantitative oriented qualitative method has been applied to understand the status and pattern of livelihood of community people at Chalan Beel area and their dependency on Beel resources. The primary data were collected using various data collecting methods such as in-depth interviews, key informant interviews, Focus Group Discussions (FGDs), and direct observation. The interview was carried out in June 2015 using a structured interview schedule. The survey team consisted of the researcher and a field assistant. Before the survey, a pilot survey was conducted by the assistant to test the completeness of the questionnaire. After such a study, researchers modified some questions to improve clarity and minimize biases. In-depth interviewing is a qualitative research technique that involves conducting intensive individual interviews with a small number of respondents to explore their perspectives on a particular idea, program, or situation (Hossain & Szabo, 2017). In the present research, in-depth interviews were conducted to understand the perspectives of agricultural farmers and landless people on the livelihood challenges they face in the study area. Additional information on the livelihood status of the community people was obtained by administering key informant interviews. Researchers interviewed chairman, members, and female members of union parishad as Key informants. Seven key informant interviews were conducted in the selected site of the study. Focus groups allow interviewers to study people in more natural settings. To understand the livelihood pattern of the community people, 12 FGDs were conducted in the study area. A transect walk was also carried out around the Beel area to observe the livelihood pattern of the community people and the changes in the dependency on the Beel resources. Secondary data were obtained from published documents, journals, articles, websites, thesis, maps, pictures, records from local institutions, etc. For this, libraries of relevant institutions and organizations were visited. "A livelihood comprises the capabilities, assets (stores, resources, claims, and access) and activities required for a means of living: a livelihood is sustainable which can cope with and recover from stress and shocks, maintain or enhance its capabilities and assets, and provide sustainable livelihood opportunities for the next generation; and which contributes net benefits to other livelihoods at the local and global levels and in the short and long term” (Chambers and Conway, 1991). Department of International Development (2005) developed the Sustainable Livelihood Approach (SLA). To assess community livelihood, SLA was widely applied. According to SLA, five asset categories form the main components of people's livelihood-natural, physical, human, financial, and social assets. Considering the situation of the study area, we took three asset categories -Human asset, financial asset, and Physical asset. Under these three categories, we selected some indicators based on the reality of the study area and research limitations.
