The Effect of Gully Erosion on Land and Property Values: Evidence From Enugu State, Nigeria

This study examines the effect of gully erosion on land and property values in Enugu State, Nigeria, with particular reference to Isiuga village in Nkerefi community, Nkanu East Local Government Area. Gully erosion severely affects south-eastern Nigeria, causing land degradation, infrastructure loss, and socio-economic disruption; however, limited studies have assessed its impacts on land and property values. Data for the study were obtained through a structured questionnaire administered to residents and property owners within the affected community. Descriptive statistical techniques such as frequency and percentage were used to analyse the socio-economic characteristics of respondents and the perceived causes of erosion. In addition, a chi-square statistical test was employed to examine the relationship between gully erosion and land and property values in the study area. Findings reveal that major factors responsible for the occurrence and expansion of gully erosion include heavy rainfall, poor drainage systems, overgrazing, and improper land management practices. The results further show that gully erosion has led to the loss of farmland, damage to residential buildings and infrastructure, and reduced accessibility within the community. Importantly, the study establishes that gully erosion has a significant negative effect on land and property values. Properties located close to erosion sites were found to attract lower market prices due to perceived environmental risks and reduced environmental quality. The study recommends the implementation of effective erosion control measures, improved drainage infrastructure, afforestation programmes, and stronger land-use planning regulations in order to mitigate erosion impacts and protect land and property values in erosion-prone communities.
