Rapid urbanization and population growth in Lagos State have significantly transformed Land Use Cover (LULC), resulting profound alterations to key ecosystem services (ES), including provisioning, regulating, supporting functions. This study presents a comprehensive analysis of LULC changes from 1985 2022, investigating their spatiotemporal dynamics associated impacts on urban expansion, surface water resources, soil health, carbon storage. (Nigeria), as rapidly urbanizing megacity, serves case illustrate these broader implications for sustainable development. High-resolution geospatial datasets, such GLC_FCS30D, were processed using QGIS Google Earth Engine spatial analysis, while the InVEST model was used quantify service changes. Our findings reveal 266% increase impervious surfaces, predominantly replacing forests wetlands. transition has reduced infiltration capacity, heightened flood risks, disrupted biodiversity-supporting habitats. Surface areas showed marked fluctuations, with significant decline 1995 2005 attributable anthropogenic activities. Soil quality identified increased bulk density, organic carbon, diminished fertility urbanized zones, undermining essential functions sequestration health. highlights urgent need land management integration nature-based solutions mitigate adverse environmental urbanization. Thus, providing critical framework policy interventions aimed at enhancing resilience evolving landscape State.

West Africa’s vulnerability to climate change is influenced by a complex interplay of socio-economic and environmental factors, exacerbated the region’s reliance on rain-fed agriculture. Climate variability, combined with rapid population growth, intensifies existing challenges. Migration has become key adaptive response these challenges, enabling communities diversify livelihoods enhance resilience. However, spatial patterns migration in risks are not fully understood. Thus, study evaluates applicability IPCC risk assessment framework map predict Ghana Nigeria, focus identifying areas potential out-migration. By integrating geospatial environmental, socio-economic, data, highlights that have higher likelihood for current baseline near future (2050). Future modeled using CMIP6 projections under RCP4.5 scenario, while providing insight into exposure. The results from compared actual migrant motivations, ground-level perspective drivers. In northern elevated hazard, vulnerability, exposure scores suggest due overall faced population. This pattern projected persist future. responses indicate factors often play secondary role, cited more frequently as findings highlight importance developing localized adaptation strategies address specific needs vulnerable areas. Additionally, management community resilience support sustainable pathways will be critical addressing climate-induced

Assessment of flood vulnerability in Osun River Basin using AHP method

Deleted Journal, Год журнала: 2024, Номер 1(1)

Опубликована: Сен. 4, 2024

Abstract Flooding is a global natural disaster that occurs when water rises over normal levels and damages infrastructure, buildings, land. Lately, substantial rise has occurred in the frequency severity of floods Nigeria due to urbanization, population growth climate change. This study aims identify areas Osun River Basin (ORB) southwest are at risk flooding as result increased rainfall patterns can induce river flooding. 10 flood factors contributing susceptibility were obtained around area. These remote sensing data analyzed using weighted overlay on ArcGIS. The Analytic Hierarchy Process (AHP) was particularly applied analysing creating maps. Results showed events probable along bank, some low-lying terrains where there high rainfall. Ogun State falls within with lowest digital elevation, therefore state very highly susceptible from tributaries River. Areas such Ijebu North, North East, East Ode identified maps created. will further help stakeholders policymakers reducing impact these areas.
