ABSTRACT:- Effective land administration systems are crucial for sustainable development, yet many countries, including Nigeria, struggle with inefficient and unsustainable land administration practices. This study evaluates the sustainability of the current land administration system in Southeast Nigeria and explores the potential of the Land Administration Domain Model (LADM) in addressing the challenges. Using a mixed-methods approach, the study assesses the current system’s performance and identifies the key challenges hindering its sustainability. The findings reveal that the current system is unsustainable, characterized by inadequate land information, inefficient land use planning, and weak institutional frameworks. The study also demonstrates that the implementation of LADM can significantly improve the sustainability of land administration in the region by standardizing land information, enhancing land use planning, and promoting good governance. The study’s results have important implications for land administration policy and practice in Nigeria, highlighting the need for a paradigm shift towards more modern, integrated, and sustainable land administration systems. The adoption of LADM is recommended as a viable solution to the land administration challenges in Southeast Nigeria, with potential applications in other regions and countries facing similar challenges.
