dc.description.abstractRight-of-Ways (RoWs) are designed for developmental projects that might be harmful or injurious to the populace. The high voltage transmission line (HTVL) RoW is one of those projects designed to be devoid of any physical development or activity originally but are later encroached upon by other land uses illegally without recourse to the risks and safety implications. This study is a geospatial analysis of the extent of encroachment on the Oworonshoki 132kV HVTL RoW in Alimosho LGA, Lagos State. Topographic Maps and High-Resolution Imagery were obtained to extract the land cover/land use (LULC) of the RoW at a cadastral-level map scale of about 1:2,000 and detect changes on both sides of the HVTL within a 15m buffer from the centre of the line approved RoW by the Transmission Company of Nigeria (TCN) over the periods 1983-2020. A handheld Trimble Juno SC GPS was used to establish the required spatial data of each pylon, while a buffer analysis within the GIS environment was adopted to generate the required RoW extent. The results show that the Oworonshoki 132kV HVTL within the LGA is 8.143km in length, having 27 pylons that transverse eight towns within an acquired RoW of 40.9ha. In 1983, the area was dominated by cultivated lands with 35.8 hectares (87.6%) which was the only form of unrestricted activity there-in. However, in 2020, 36.3ha (88.7%) of the RoW has been illegally permeated with built-up areas. The study concluded on the poor encroachment enforcement and the health/safety implications of built-up areas around the HVTL.en_US
