Title: SPATIAL DISTRIBUTION OF CLIMATE PARAMETERS AND TREND PATTERN ANALYSES ACROSS THE SOUTH EASTERN PART OF NIGER STATE, NIGERIA Authors: Baba, M.; Akinpelu, A.; Faruna, S.O.; Olaniyi, A.M. Abstract: The magnitude of climate variability varies according to location. Hence, examining the spatiotemporal dynamics of meteorological variables in the context of climate change which have influence on the agricultural, social economy activities of human lives is imperatives. This study thus seeks to present the spatial distributions of climate parameters (temperature, precipitation, surface pressure and wind speed) and trend pattern analyses across the nine local government areas (LGAs) in the eastern part of Niger state using Mann-kendell and Sen’s slope statistical test. Merra2 meteorological dataset is processed directly from the National Aeronautical Space Administration (NASA) in affiliation with global modelling Assimilation office using the principles of retrospective analysis in refining earth data. The climate data (Merra2) covered the range of ten years (2010-2019), which was further filtered and sorted before been used. The Merra2 was validated using Nigeria Meteorology Agency (NiMET) dataset and it indicated that there was a strongly correlation with the climate parameters dataset apart from wind speed (WS) which had a poor correlation. The trend pattern analyses were computed for the ten years using Mann-Kendall and Sen’s slope estimator statistical template at the 95% confidence level. Temperature (T), precipitation (P) and WS indicated a negative trend pattern while surface pressure (SP) indicated positive trend pattern for the study area. This might lead to unexpected changes in the weather conditions and subsequently have extended effect on the social and economic activities in the study area. Therefore, further study should be carried out to investigate such situation in order to provide adopted strategies to mitigate the extended effect.

Title: Suitability Location of Solid Waste Collection Points for Chanchaga Local Government Area, Niger State Authors: Baba, M.; Musa, A.W.; Olaniyi, A.M.; Bala, M.K. Abstract: Population growth and uncontrolled urbanization has made solid waste management an imperative issue for environmental management and sustainability. The study conducted site suitability analysis for solid waste disposal in each wards of Chanchaga Local Government Area (LGA) of Niger State with a view to recommending most suitable sites for solid waste collection in the study area. The data used for the study was Landsat 8 OLI of 30m spatial resolution, soil map was obtained from Food and Agricultural Organization (FAO), Digital Terrain Model (DTM), Administrative map and the geo-location of the existing solid waste collection points in Chanchaga LGA. The derived factors were reclassified and spatially analysed based on the minimum standard setup by Environmental Protection Agency (EPA), 2006 for high, moderate and least suitable waste collection site. The outcome depicted that about 90% of the solid waste collection site does not meet up with the standard setup by EPA, 2006. Furthermore, the study revealed that most residential buildings were located in a confine radius of less than 50m to most of these collection sites, which is inappropriate and unacceptable. Indiscriminate dumping of waste within residential areas, water body, road network and drainage systems should be discouraged. Provision of waste cans for household and frequent evacuation by the relevant authorities should be encouraged. Finally, based on the EPA 2006 minimum standard, suitable solid waste collection sites were determined and recommended for use in the study area.

Title: Exploring the Critical Barriers Towards Women Participation in Surveying and Geo-Informatics Practices Authors: Gbenga, P.O.; Bello, A.O.; Olaniyi, A.M.; Idris, A. Abstract: Surveying and geo-informatics stand as a significant field at the intersection of science, technology, and spatial management, playing a crucial role in informing decision-making across various industries. However, the surveying and geoinformatics field suffers from the underrepresentation of women professionals. This underrepresentation carries significant implications hindering diversity of knowledge and skills. In order to build a more inclusive and equitable professional environment, the study aims to identify and analyse the identified barriers to offer insight and strategies to enhance women's participation. Data were gathered using a mixed-methods (sequential exploratory) approach, which included interviews and structured questionnaires (five Likert scale) with professionals in the field. Twenty-five participants and 138 responses were considered for the study. Statistical tests such as Cronbach's Alpha, mean ranking, one sample t-test, Chi-square, Kruskal Wallis, and factor analysis were conducted to investigate the significance and relationship between the identified barriers. The result shows that the participation of women in the surveying and geo-informatics field is low. Similarly, the study shows that the barriers are critical to the participation of women in the field, considering their significance level. In addition, a rotation of the component matrix reveals three dimensions: equity and inclusion, career advancement and assistance, and gender equality and empowerment. These factors offer a thorough foundation for comprehending the many difficulties women in the field encounter. The study developed various strategies tailored to mitigate each barrier component. The findings of this study add to the body of knowledge on gender differences in surveying and geo-informatics practises and offer policymakers, organisations, and stakeholders valuable insights. Eliminating these obstacles will improve gender diversity, encourage inclusivity, and fully utilise the talents of women, ultimately resulting in a more innovative and sustainable surveying and geo-informatics profession in Nigeria.

Title: Geomorphic Assessment of Flood Hazard within the Urban Area of Chanchaga Local Government Area, Minna, NIGERIA Authors: Adesina, E.A.; Adewuyi, A.I.; Olaniyi, A.M.; Morenikeji, G.; Njoku, D.O. Abstract: Pairwise comparison, Analytical Hierarchy Process (AHP) and Geographic Information System (GIS) has been recently used to assess flood hazard. It has been used to carry out Multi-Criteria Analysis (MCA) of various geomorphic factors by assigning weight based on the presumed impact of each factors on flooding. This study considered six factors which include; Slope, curvature, landcover, elevation, distance from river and soil using Rafinsenyi river in Chanchaga Local Government area, Minna-Nigeria, as study area. Review of literatures showed that methods of assigning weight are hypothetical and inconsistent, this research thus take input from researchers in field of hydraulics, hydrology and disaster management. The weight with 0.029 as the least consistency ratio was used. Data used include; DGPS data, Satellite Images, Digital Soil Data. Landcover Maps, Digital Elevation Models (DEM), Soil Maps and Profile Curvature maps were generated. Weighted overlay operation was carried out in ArcGIS to produce a Flood Risk Map. Livisol (Loam) soil reveals why farmers and traders indiscriminately settle along floodplain. 6 of the 20 hectares of study area lies between 216 and 220 metres above mean sea level, putting residential building at high risk of flooding.
