Introduction: North Bengal (NB) occupies a strategically important and spatially unique location within the broader of West Bengal province (WB) and forms part of an important sub-region of Eastern India, which, in northern WB, is made up of the eight districts. The physiography of North Bengal is characterized by significant diversity. It dominates throughout the hill and foothill region's tea plantations, horticulture and tourism. Objectives: The study has tried to determine the geographic location and condition, the regional development gap between South Bengal (SB) and North Bengal (NB) and also to evaluate what affect the geography, the connection between these two regions, and how much bias in historical government decisions has played a role in generating different development levels in these two different areas. Research Methodology: The Research Design has implemented a qualitative-quantitative Mixed Method Approach, drawing upon secondary statistical analysis supported by the conceptual/theoretical application of regionally devised development processes. Results and Discussion: The interconnectedness of natural conditions and human actions/decisions has resulted in many of the outcomes in the region, including environmental sensitivity and vulnerability to disasters and resource dependence. The disparities in poverty, literacy and infrastructure between North Bengal and South Bengal are due to numerous causes and are highly interconnected. Conclusions: There are equal amounts of importance placed on investing in education, skill development, and healthcare as they are all essential elements of human capital in achieving long-term regional development.
