Efficient land administration systems (LAS) are critical for promoting socio-economic development, particularly in rural areas like Umunneochi Local Government Area (L.G.A.) in Abia State, Nigeria. This study explores the role of LAS in facilitating secure land tenure, economic growth, and sustainable development in Umunneochi. Using a mixed-method approach, including surveys, interviews, and secondary data analysis, the study identifies challenges such as outdated land records, bureaucratic inefficiencies, and lack of digitalization. It proposes strategies for improving LAS, including the adoption of Geographic Information Systems (GIS), legal reforms, and community engagement. The findings highlight that an efficient LAS can enhance agricultural productivity, attract investments, and reduce land disputes, thereby fostering socio-economic development in Umunneochi.
