This study examined the effects of topographic barriers on rural water accessibility and their implications for socio-economic development in Itu Local Government Area, Akwa Ibom State, Nigeria with a view to address topographic constraints. The study adopted a mixed-methods approach involving household surveys, key informant interviews, field observations and focus group discussion. A total of 310 household heads were selected from ten rural communities using a multistage sampling technique, while 20 key informants provided qualitative insights into water resource, accessibility challenges and management. For methodological illustration, the results presented in this paper are based on a simulated dataset consistent with the study design. The findings indicate that topographic barriers, including steep slopes, elevated terrain, deep groundwater tables, rocky subsurface conditions, and poor road accessibility, significantly influence rural water accessibility. Approximately 58.4% of households spent more than 60 minutes collecting water, while over one-third continued to depend on unimproved water sources. Limited water accessibility was associated with reduced agricultural productivity, increased healthcare expenditure, loss of productive time, lower household income, and increased workload for women and children. The study further demonstrates that communities located on higher terrain require deeper boreholes and greater financial investment in water infrastructure than those situated in lowland areas. The study concludes that integrating topographic analysis, hydrogeological investigations, and Geographic Information Systems (GIS) into rural water planning is essential for improving equitable access to potable water. It recommends increased investment in climate-resilient water infrastructure,solar-powered boreholes, improved rural road networks, and community-based water management strategies to promote sustainable rural development.
