Globally around 2 billion people (⁓ 61% of the total world population) are engaged in informal sector, whereas the percentage rises to more than 80% in India (ILO, 2018). Since 25th March 2020, the COVID-19 outbreak and lockdown in India due the COVID-19 pandemic has created an atmosphere of extreme uncertainty and raised several questions. Global analysts have already suggested that, for many developing countries, the economic consequences could be more crippling and devastating than the disease itself. Livelihoods are vital means of making a living. The terminology Livelihood is not synonymous to mere income generation. It encompasses people’s capabilities, assets and activities required to secure the necessities of life. Undoubtedly, globally COVID-19 has become an unprecedented shock; however, any kind of shock tends to reinforce the existing socio-economic-political and environmental stresses, problems and inequalities. Therefore, there is a need to understand how and to what extent this pandemic has affected and going to affect the lives and livelihoods of a coastal rural community entirely dependent on rain-fed agriculture, small-scale fisheries (inland and marine) and other riverine as well as forest resources for their subsistence. This paper attempts to explore the impact of COVID-19 outbreak and lockdown the livelihood choices and daily lives in the coastal rural stretches of Indian Sundarbans delta region. This study incorporates a telephonic rapid assessment survey method to understand the impact of COVID-19; for assessing the minute detailing and pathways of livelihoods, this paper refers to findings from a questionnaire-based household survey of the concerned area carried out by the author herself. The findings support the argument that the shock of COVID-19 will further aggravate the preexisting socioeconomic issues. The long withstanding local problems as well as backwardness and COVID-19 are mutually reinforcing in nature; the social cost and economic cost of this pandemic is immense. Asset loss, changes in dietary pattern and consumption, increased indebtedness, increased dependence on natural resources are some of the major findings.
