Impact of Cadastral System Reforms on Land Market Development in Rivers State

Cadastral system reforms are theorised to stimulate formal land market development by reducing transaction costs, improving tenure security, and increasing the creditworthiness of land-based assets, yet empirical evidence on reform outcomes in Nigerian state land markets is limited and methodologically inconsistent. This study empirically investigates the impact of cadastral system reforms implemented in Rivers State between 2016 and 2022, including the introduction of the Rivers State Geographic Information Agency, electronic title processing, and systematic boundary adjudication, on land market development indicators. A quasi-experimental difference-in-differences design compares land transaction volumes, formally registered property prices, and mortgage origination data for Rivers State against a control group of three comparable states without equivalent reform programmes. Spatial analysis of land registration density before and after reform implementation is conducted using cadastral database records from RIVGIS, examining changes across urban, peri-urban, and rural zones. Transaction cost analysis using structured surveys of land market participants quantifies changes in time and monetary costs of formal title registration. Results indicate a statistically significant 42 percent increase in formal property transactions in Port Harcourt and a 27 percent reduction in average title registration time post-reform, with effects concentrated in peri-urban zones where informal tenure previously dominated. The study contributes empirical methodology and findings to the land tenure reform evaluation literature in Nigeria. Keywords: cadastral reform, land market, Rivers State, RIVGIS, tenure security.
