D. Block of South 24 Parganas District, West Bengal Authors: Paul, Rajat Kumar; Baidya, Arup; Alam, Asraful; Satpati, Lakshminarayan Abstract: The Sundarban is a region of complex diversities both in terms of its physical and cultural environments. Three very important issues in the Sundarban are poverty, embankment and transport-communication. All of these issues are related to natural calamities. Cyclonic hazards are very common in the Bay of Bengal, as it severely damages lives and properties in the region. The principal objective of this study is to assess cyclone induced vulnerability and change in land utilization pattern in a coastal location of the humid tropics, for which G-Plot of the Indian Sundarban has been selected as the case study area. Both primary and secondary data have been used to analyse the same using quantitative as well as qualitative methods. Field survey was conducted by administering semi-structured questionnaires among 10 households from each mouzas of G-Plot, thus totalling 90 households for the entire area were randomly surveyed. With the adverse effects of mostly the cyclones, the nature of land use and land cover has changed significantly in the area. Out of 5 land cover features, the amount of area under mangrove and non-mangrove land (area covered by all the natural vegetation except mangrove trees) has decreased, while fallow land, water body and sandbar have increased. Settlement is one of the most important land uses, and it is found to be decreasing in the southern part of G-plot, but it has been increasing in the northern part, which can be a testimony of cyclonic effects. Based on vulnerability indices, this study indicates that the mouzas located in the southern portion of G-plot are highly vulnerable to cyclonic hazards compared to its northern counterpart. 2021-04-01T00:00:00Z https://ir.vidyasagar.ac.in/jspui/handle/123456789/5951 Title: Livelihood and Environmental Sustainability Analysis Using Aquaculture-based Indicators: A Study on Selected CD Blocks of Purba Medinipur District, West Bengal Authors: Mallick, Suraj Kumar; Rudra, Somnath Abstract: Aquaculture-based sustainability can be defined as a continuous and harmonic interaction with the aquaculture ecosystems to the local communities. The present study was based on empirical analysis of some environmental and socio-economic databases to accentuate the sustainability of aquaculture activity and quality of standard of living. Therefore, water samples from fresh and salt water were tested to analyse the physicochemical characteristics like pH, SO4, F-, AS, DO, BOD and soil samples were analysed for the measurement of soil quality through pH, NH4+, HPO4 2-, K+ as environmental parameters and 40 questionnaire survey hadbeen conducted for the analysis of livelihood scenario. All these environmental parameters were tested and socio-economic indicators were equated at the standard scale to describethe aquaculture sustainability and its significant effect on environment and local people. The results showed that the degree of aquaculture from fresh water and salt water had influenced on the local economical sustainability but environmentally salt water aquaculture had some risks. Therefore, it has urgently needed some governance on the water quality with proper management. Finally, the result recommends that this area have potential for aquaculture activity in an organic way and this will be really helpful for maintaining the aquaculture management system and social well-beings in study area at the upcoming days. 2021-04-01T00:00:00Z https://ir.vidyasagar.ac.in/jspui/handle/123456789/5950 Title: Assessing and Quantif ying the Factors Associated with Livelihood Diversification in Tourism Sites: An Insight from Coastal West Bengal, India Authors: Saha, Jayanta; Paul, Suman Abstract: Coastal tourism has been reported as an emerging arena of tourism growth worldwide due to availability of 3S (i.e. Sun, Sea and Sand). This study try to evaluate the impact of coastal tourism on the rural livelihoods of Mandarmani and Tajpur area of West Bengal, India thorough face-to-face survey on 23 villages located within the vicinity of tourism sites. Tourism generally makes a positive impact on the local economy though this tourism area experienced disparity in economic sustenance based on its site and situation. Total of 412 questionnaires have been administered to 23 villages at random to household heads. The result shows the more involvement of beach facing villages minimise the poverty with high to very high livelihood diversification. For the assessment of controlling factors to livelihood diversity, multi-linear regression analysis has also been adopted and education, asset index, access and availability of credit has been found as major controlling factors for livelihood diversification in the study area. Such baseline information will be vital for the policy planning to the stakeholders in future. 2021-04-01T00:00:00Z https://ir.vidyasagar.ac.in/jspui/handle/123456789/5949 Title: Assessment of Trends and Variability of Post-Monsoon Rainfall for Some Selected Districts of Gangetic West Bengal, India Authors: Goswami, Asutosh; Sarkar Sen, Tuli; Kamila, Amrit; Parvin, Jasmin; Sultana, Farhin; Bal, Abhinanda; Paul, Ashis Kr. Abstract: Trends of Indian rainfall have been extensively studied by many researchers but the subject still remains complicated due to its high spatio-temporal variability. The post-monsoon season is a period of transition between the south-west monsoon (June-September) and the dry cool winter season (December-February). It broadly coincides with two months namely October and November. Harvesting of kharif crops entirely depends on the nature and characteristics of post monsoon weather. In the present study, an attempt has been made to identify the trend and variability of postmonsoon rainfall by analyzing monthly rainfall data of these two months (October and November) from 1961 to 2010 of some selected districts of Gangetic West Bengal where rainfall is the prime factor for the successful growth of agriculture. 2021-04-01T00:00:00Z
