    Assessment of livelihood vulnerability in the riparian region of the Tista River, West Bengal, India
    (Springer, 2022-04-22) Mandal, Deepak Kumar; Mitra, Rajib
    The Tista floodplain is one of the major food baskets of North Bengal and is sensitive to a multitude of issues regarding vulnerability. The riparian areas and the river island or charland of the lower Tista River basin in India, specifically from Sevoke to the Indo-Bangladesh border, generally suffer due to flood-prone, river course shifting, limited livelihood activities, low adaptive capacity, and poor accessibility. The present work is conducted to assess the livelihood vulnerability based on the livelihood vulnerability index (LVI) framework of the agriculturedependent riparian villages and the charlands of the River Tista in the Jalpaiguri district. Total 337 households of five villages from the Mal and Maynaguri block at the left bank of the Tista River were selected to conduct the field survey. The livelihood vulnerability was assessed based on eight major components (viz., socio-demographic profile, health condition, livelihood strategies, food support, water support, climatic variability, flood hazards, and social safety) and 42 sub-components. The three contributing factors, i.e., adaptive capacity, sensitivity, and exposure, have been combined to calculate the livelihood vulnerability employing the LVI and LVI-IPCC methodologies. The outcome of the study exhibit that LVI scored highest in Premganj Majhiali (0.436), followed by Basusuba (0.403), Uttar Marichbari (0.349), Domohani (0.335), and Chat Rarpur village (0.328). According to the LVI-IPCC results, Basusuba has the most vulnerability (0.015), whereas Domohani has the least (0.007). In terms of flood hazard, variations were noticed based on increasing distance from the river. Lack of adaptive capacity prevailed in the villages with significant flooding events. Building awareness of the inhabitants will be an effective way to improve the adaptive capacity of the rural villagers. Therefore, giving priority to the policies depending on the natural environment of the active flood-prone region would make long-term sustainability.

    Impact of Tista River on the socio-economic life of the riparian people of Jalpaiguri District, West Bengal, India
    (University of North Bengal, 2022) Mandal, Deepak Kumar; Mitra, Rajib
    A river is a lifeline for any region. The river basin provided the floodplain, which is directly affected by the people's habited and live/I/roods. Rivers have an economic. political and social impact on the culture of the people. However, It also plays a role of negative character for the adjacent people. Thus a river in a region plays a dual character in the behaviour in an a/111vlal channel. The River Tista is /mown as the lifeline of Jalpalg11ri District as ii plays a noticeable role In the development of the people. The mighty Tis ta is very import an/for the riparian people due to its water resources, small-scale navigation and facilitating agric111/11ral prod11clion. Here are the community development Blocks. namely. Rajganj and Jalpaiguri (at the right bank}, Mal and Maynag11rl (at the left bank) along the Tis/a River of Jalpaiguri District, has been selected as the study area. Throughout the present study, the authors have tried to analyze various fields where the Tisla River influenced the socio-economic aspects of the riparian inhabitants and highlighted the impact of increased human intervention on theĀ· river. For this purpose, primary and secondary data have been collected and presented through various cartographic techniques. The study helps to manif cst the role of the Tista River in the concerned region.
