The construction of one of Mizoram's major infrastructure projects, Serlui-B Hydel Project was intended to enhance energy production and bring about socio-economic development. However, its impact on the surrounding communities, particularly on the accessibility and availability of essential facilities remains insufficiently examined. This study evaluates the Facility Deprivation in areas adjacent to Serlui-B Dam, aiming to understand how the dam’s presence has affected the villages. The study area encompasses a 10 km radius from the dam site/embankment, as specified in the “Standard Terms of Reference for EIA/EMP Reports for Projects/Activities Requiring Environmental Clearance Under EIA Notification, 2006” by the Ministry of Environment, Forest and Climate Change, Government of India. Primary data were collected using random sampling method through interviews and questionnaires. The study then measured the Deprivation Index and Facility Deprivation Index following the methodologies developed by Bhattacharjee and Wang (2011). Our findings revealed contrasting levels of deprivation, highlighting how the same project can have varying impacts on different segments of society. Disparities between rural and semi-urban areas are evident from the analysis, indicating that those who sacrifice the most for the sake of development may have benefited the least.
