“…In a few years, the harvesting is becoming minimal, mainly because of the unlawful and intensive aggression of the farmers towards the enormous accumulation of wealth. Studies also have mentioned that the invested land cannot be reformed for any other use (Rajarshi and Santra 2011 ; Adnan 2013 ; Maiti 2019 ; Maity 2019 ; Rajakumari et al 2020 ). This study also found the same consequences.…”

“…In this district, different coastal C.D. blocks such as Deshapran, Ramnagar I, II, Contai I, II, III, are already facing various positive as well as negative livelihood issues related to shrimp farming (Dutta et al 2016 ; Maiti 2019 ; Maity et al 2019 ; Rajakumari et al 2020 ). However, these coastal blocks are tide-affected and have minimal production in agriculture.…”

The present study attempted to understand the dimensions of changing agrarian livelihoods because of haphazard adaptation of capitalistic shrimp aquaculture. Specifically, using multi-temporal Google-based geodatabase, we quantified the artificial conversion of agrarian landscape in an inland freshwater region of coastal Bengal. Further, we examined the long-term viability of transformed livelihoods by adopting a modified version of the Sustainable Livelihood Approach (SLA). The assessment of changing livelihoods was based on empirical information acquired through field surveys, focus group discussion (FGD) and key informant interviews (KII). Results from the geostatistical analysis depicted that the shrimp culture in the research area was very recent. In 2010, only 0.03 percent of the total area was occupied by shrimp ponds. However, within a decade and an expansion rate of 18 percent/annum, the conversion spread to 1/3 of the total study area. The findings also clarified that the adaptation of shrimp cultivation increased the overall profit by 6400 USD/ha/year over agricultural output, and resulted in a quick rise in the standard of living for the shrimp farmers. However, in the long run, due to decreasing productivity and salinization of the surrounding land, the conversion resulted in massive depeasantization, augmentation of wasteland, and biased wealth accumulation led to a wide rich-poor gap. Therefore, the entire ecosystem will suffer in the near future, if the local government does not strictly impose Standard Operating Procedures (SOPs).

“…However, positive growth in area and productivity could be observed during the period II which might be due to development of technology, awareness among the farmers of profitability of the venture and introduction of new species Pacific white shrimp Penaeus vannamei (Bhattacharya, 2008;Animesh et al, 2019;Pallavi et al, 2021). However, in overall period, area (1.52 per cent), production (5.94 per cent) and productivity (4.55 per cent) showed positive growth rate due to improvement in…”

Growth trends and decomposition analysis of area, production and productivity of shrimp in the state of West Bengal were carried out for a period of 16 years from 2005-2006 to 2020-21 by splitting the production data into two sub-periods i.e. period I 2005-06 to 2012-13 and period II 2013-14 to 2020-21. The growth rates were calculated using exponential function while the instability in the production was worked out using coefficient of variation (CV) and Cuddy Della Valle's Instability Index (CDVI). The change in output in terms of relative contribution of area and yield was estimated by using Minhas decomposition model. During the first sub period, the compound growth rate for the area (-6.38) of shrimp culture was found to be significantly negative (p<0.05) while production (14.55 per cent) and productivity (23.12 per cent) were positively significant. Whereas during second sub period, the growth rate of shrimp production (-57.54 per cent) was negative while area (5.54 per cent) and productivity (60.05 per cent) were insignificantly positive. However, the study revealed that the overall compound growth rate of area (1.52 per cent) and production (5.94 per cent) of shrimp in West Bengal for the entire study period from 2005-06 to 2020-21 were found positively insignificant. The maximum growth in productivity was observed during the sub period II (60.05%) followed by sub period I (23.12 per cent). The instability indices i.e. CV and CDVI were found low during all the periods in the case of area. Goodness of fit under cubic model proved as best fit among the parametric models fitted to the area, production and productivity of shrimp culture in the state of West Bengal. The area effect was found to be 100.31 per cent, whereas yield and interaction effect were 1.72 per cent and (-) 0.94 per cent respectively in the study period. Finally, the analysis emphasized that the decomposition analysis and area effect played key role in making differentiation in the shrimp production of West Bengal.

“…Access to various sources and channels of agricultural information is essential for meeting farmers' needs and uplifting the tribal economy (Yadav et al, 2011; Meena and Sharma, 2012) [13,14] . In the face of global food insecurity, driven by increasing population and stagnating food grain production, effective information dissemination through mass media is paramount (Lahiri, 2016; Maity et al, 2013) [12,15] . Considering the importance of mass media in agriculture, this study aims to assess the utilization pattern of mass media by hill farmers in Meghalaya, focusing on their preferences regarding place, time, and purpose of usage.…”

Agricultural information dissemination through mass media is crucial for the development and transfer of agricultural technologies, particularly in regions like Meghalaya, where traditional farming practices persist amidst challenges like weather variability and limited access to communication technologies. The study investigated the mass media ownership, frequency of use, preferred locations and times of use, and purposes for engagement with mass media of farmers in Meghalaya during 2023. The study was conducted in three districts of Meghalaya viz., Ri-Bhoi, West Jaintia Hills, and West Garo Hills. Two crops were chosen from each district: pineapple and ginger from Ri-Bhoi, turmeric and tomato from West Jaintia Hills, and cashew nut and areca nut from West Garo Hills. Using random sampling with proportional allocation, 60 farmers were selected from each crop in four villages, resulting in a total of 360 respondents. The respondents were chosen from 12 village clusters, totalling 24 villages. The data were collected with a pre-structured interview schedule. The study revealed that the majority of the respondents had a medium level of mass media utilization. The predominance of medium-level usage suggests balanced utilization patterns. Ownership and utilization rates vary across media types, with social media leading in ownership (63.05%) and mean utilization (1.98). Print media shows lower rates. Purpose of usage of mass media include newspapers for various types of news (28.05%), magazines for entertainment (8.89%), TV for entertainment (59.16%), and social media for entertainment (69.44%). Accessing media occurs predominantly at home and at any time, with social media being accessible at all times. Understanding these mass media utilization patterns is crucial for policymakers and agricultural stakeholders to effectively disseminate information, promote agricultural development, and address farmer problems in Meghalaya's hill regions. Leveraging mass media channels, including mobile telephony and social media, holds significant potential in bridging information gaps and empowering farmers in remote areas.
