Abstract

The Federal Government of Nigeria recently announced the plan for new airports across the country in order to ease the air transportation system across the country and its connectedness to other parts of the world. However, the adequacies of the declared sites were not empirically supported through a carefully designed suitability assessment; that assured their appropriateness environmentally and geospatially. Thus, this paper examines the geospatial suitability evaluation of the proposed Airport in the Eti-Osa Local Government Area in Lagos State. A multi-criteria suitability analysis (MCSA) concept in a geospatial environment was adopted, using the analytic network process (ANP)del based on reviewed criteria for the airports' site suitability selection. Different thematic layers of the land cover for the assessment were achieved through the geospatial capabilities of Geographic Information System and Remote Sensing, with the various factors’ priorities from the ANP model in the final analysis of alternative suitability sites for this proposed airport. The final suitability model revealed different levels of this suitability for consideration by relevant decision-makers for better-informed decisions about the project.

Abstract

Assessment of coastline changes is crucial to coastal development and management. The Lagos coast is still prone to sediment trap and erosion to date despite the construction of the three moles to solve siltation challenges; moreover, their rates and distributions are yet to be adequately evaluated. This study examines changes along the Lagos West Mole and the possible degree of distributions along the coast between 1984 and 2018 for six epochs. Acquired Landsat imageries were processed to delineate water boundary using Modified NDWI and extract the respective coastlines from the classified waterbodies. Coastline changes were quantified using Digital Shoreline Analysis System (DSAS); the Relative Shannon Entropy (RSE) model was used to measure the degree of concentrations of accretions and/or erosions. Results revealed more profound coastal accretions than erosions; whereas RSE values portrayed dispersed accretions more than erosions. Hence, the outcomes can aid stakeholders’ informed decisions concerning coastal protection and management.
