Compared to surface water, it accounts for about 30% of the Earth’s freshwater. The demand for water for various purposes have drastically increased. Surface water cannot meet this demand, and so, the dependency on groundwater has increased. An efficient and sustainable means of exploring for groundwater is necessary. This research methodology involves utilizing Remote sensing and Geographic Information Systems (GIS) for detecting aquifer zones in Garaku. Seven thematic maps (Geology, lineament density, drainage density, slope, LULC, rainfall, soil maps) were generated from remotely sensed data. Using Multi-criteria DecisionAnalysis-Analytical Hierarchy process, the thematic maps assigned weights. Rainfall ranking the highest was assigned 40.2%, Geology ranked 22.6%, lineament density ranked 14.6%, drainage density ranked 9.7%, soil ranked 6.1%, slope ranked 4%, and land use/cover ranked the lowest at 2.8%. The thematic maps were integrated to ascertain groundwater potential zones. The analysis revealed that 8% of the study area has very poor groundwater potential, 67% has poor groundwater potential, 24% shows good groundwater potential and 1% shows very good groundwater potential. A depth model was produced from the analysis of profiles taken along a few selected target zones. This revealed subsurface depressions within the groundwater potential zone. This study demonstrated the efficacy of remote sensing and GIS methodologies in mapping groundwater targets, and the produced maps can be used for groundwater production and management planning. Regular updates to the groundwater potential mapare essential to account for changes in land use, climate, and other factors influencing groundwater availability.

As the Government department is vested with the responsibility of processing building permits, monitoring urban development and management, and the overall implementation of the Abuja master plan, the adoption of a purpose-built Geo database is indispensable. Any computer application that is aimed at aiding Urban planning and monitoring must have a robust GIS database that can support making meaningful analyses, predictions, forecasting, simulation, and informed decision-making. It is observed that the department generates a lot of data through reports from field site officers at all the district offices, these data do have geo-spatial attributes but are not being stored appropriately as the existing system is devoid of GIS database, this ends up in duplications of efforts as the reports are repetitive, also losing the opportunity to create, store, retrieve data and map relevant important trends. The future in Urban Planning and management is in exploiting the synergies between city planning and three techno-scientific domains including Big Data, Data Science and Geographic Information Systems, this will collectively constitute an emerging field known as Geospatial Artificial Intelligence (GeoAI) The department of Development Control currently does not have a Geospatial data base to correlate with maps obtained from the Abuja Geographic information system in order to make meaningful analyses and make informed decision. The integration of a Geodatabase into the Development Control Information System will lay the foundation for collecting credible data for Geo-Spatial Artificial Intelligence in Abuja, and primarily strengthen the Department in undertaking its responsibilities and enhance the efficiency of urban services and functions, contribute to the production of spatial data and serve as a decision-making support tool Main Thesis 2024-09-10T00:00:00Z http://repository.aust.edu.ng/xmlui/handle/123456789/5150 Urbanization has significant impacts on the urban landscape of Abuja Municipal Area Council (AMAC), Federal Capital Territory (FCT). This study utilizes remote sensing data and Geographic Information System (GIS) technique to analyze the Land Use Land Cover (LULC) patterns in Abuja Municipal Area Council (AMAC) and then identified the dominant land use and land cover types, conduct an analysis to investigate the factors, trends and socio-economic impacts of urbanization in AMAC, assess the implications of rapid urbanization, including issues related to housing and infrastructure and the propose strategic interventions and recommendations for effective urban management in Abuja. Landsat imageries for the year 2014, 2019 and 2023 were acquired and subjected to digital image processing such as the feature extraction, image classification where samples were trained through the means of supervised classification (maximum likelihood), post-classification process and then data analysis such as the descriptive statistics, spatial analysis and change detection analysis in order to detect the level of urban expansion in the area was carried out. Questionnaires were also administered to be able to identify the factors and drivers of urbanization within AMAC. The study shows that the transformation of AMAC has presented challenges which resulted in environmental degradation, including air and water pollution, inadequate housing, poor waste management, inadequate power supply and traffic congestion causing significant socio-economic problems that requires strategic planning and sustainable practices. The Land Use Land Cover analysis for the year 2014 revealed that there was a gradual growth in the built-up region with an area of 201.306square kilometers (12.7%) land covered. Vegetation possessed an area of 1308.67square kilometers (82.55%) while barren land covered an area of 64.626square kilometers (4.1%) and water occupied an area of 10.72square kilometers (0.7%). In the year 2019, it showed how vegetation decreased over time reading 1179.696square kilometers with a percentage of 74.4%, meaning that within a span of five years, vegetation had decreased by approximately 8.15%. The built up region had also increased to cover an extra 54.571 square kilometers. Barren land also increased to an area of 144.678 square kilometers (9.1%) and then waterbody, which decreased with an area of 5.654 square kilometers (0.4%). Lastly for the year 2023, it further described how vegetation had decreased over time to cover an area of 990.107 square kilometers (62.5%) and then the built up region had also increased in area, now totaling up to 292.707 square kilometers (18.5%). Barren land also increased with the reading for 2023 carrying an area of 298.146 square kilometers (18.6%) and then finally waterbody, which decreased to an area of 4.331 square kilometers (0.2%). Based on the results shown, it is clearly evident that the Federal Capital Territory, especially AMAC is susceptible and exposed to a lot of challenges and effects ranging from environmental implications, economic implications, societal implications and even impacts with regards to policy and regulatory framework. To address the problems that come with urbanization in Abuja, here are a few recommendation; create policies that promote fair access to opportunities and resources for all individuals, including those living in informal settlements, ensure that many residents have access to power and that public transportation infrastructure is upgraded. This will largely cut expected emissions and ensure that inexpensive, dependable, sustainable and contemporary energy is available Waziri, Bawa Abubakar This research harps on integrating Geospatial data components into the existing relational database of the Department of Development Control, Abuja.
