While it is anticipated that there would be some similarities amongst spectral Vegetation Indices (VIs) because the majority of the indices use the red and NIR bands, it is also expected that there would be some variances. The NDVI, derived earlier by Rouse (1973), and is the commonly used VI, there have meagre understanding of the relationship bet...

Knowledge of land policies and legislation by communities plays a major role in promoting accountability and accessing land and reduction in litigations and conflicts among citizens. This paper focused on the experiences of two African countries in the delivery of land and the impacts of land corruption on communities. Short case studies were prese...

The effect of improper waste disposal on man’s health and environment due to the closeness of solid waste dumpsites to underground water sources in some parts of the world has raised issues of serious concern. This study thus sought to examine groundwater quality dependence on the spatial proximity of dumpsites in Samaru, Kaduna state-Nigeria. The...

Satellite imageries have in the recent past gained popularity in the areas of geo-informatics and geo-positioning because they provide global coverage and are cost-effective. Nevertheless, the use of these services poses questions on their spatial data quality in terms of positional reliability and accuracy, which have implications for their applic...

Change Detection Land use Land cover Landsat One of the most important domains of human-induced environmental change has been identified as land transformation. Determining what feature of the land is changing to what, i.e., which land-use class is moving to the other, is a key part of change detection. With the availability of a broad spectrum of...

The increased flood incidences experienced all over the world due to climate change dynamics call for a concerted effort towards forestalling future hazards. This study thus, identified the areas that are susceptibility to floods in parts of the Makera district of the Kaduna South Local Government Area in Nigeria using geospatial techniques. Geogra...

This is a presentation of a conference paper on a study that analysed the geometrical characteristics of mining-induced land degraded areas of the Jos South LGA of Plateau State-Nigeria. The degraded sites of the study area were assessed using multi-sensor satellite imageries of Landsat 8 (2016), SPOT 5 (2012), and Quickbird-2 (2010).

Nigeria reported its first case of the novel coronavirus (COVID-19) infection in February 2020. The COVID-19 attained World Health Organisation (WHO) pandemic status a month later. As at 13th August, 2020, over 48000 cases have been confirmed in the country with at least 950 deaths. Katsina State recorded its first death on the 7thof April, 2020. S...

For several decades, Nigerian cities have been experiencing a decline in their biodiversity resulting from rapid land use land cover (LULC) changes. Anticipating short/long-term consequences, this study hypothesised the effects of LULC variables in Akure, a developing tropical rainforest city in south-west Nigeria. A differentiated trend of urban L...

This study mapped the occurrence of COVID-19 in Katsina State, at the Local Government level through the use of readily available data and presents the maps in a form easily understood by the Hausa community.

Ecological degradation is an environmental challenge faced across the globe. Mitigation strategies are vital in any attempt to understand and regulate the process of land surface degradation. The study conducted a land use/cover assessment using multi-spectral datasets. The study adopted datasets from the Landsat programme as it provides an extensi...

The devastating effects of soil erosion on man, food and the environment in different parts of the world cannot be quantified. This study thus, modelled soil erosion using Revised Universal Soil Loss Equation (RUSLE) and Geospatial Information System (GIS) in Zaria Local Government Area (LGA). Rainfall data, soil, digital elevation model (DEM) and...

There is concern of flood increase in recent decades due to its effect on human life and man's environment. This study thus mapped and analysed flood risk communities around the Usman dam in Abuja, Nigeria, using geospatial techniques. Spatial data were captured which included positional coordinates, Landsat enhanced thematic mapper (ETM), soil map...

In Nigeria, the rising levels of used/poorly maintained vehicles are contributing to most urban air pollution with possible repercussion on the general public health. This study evaluates the inferences of vehicular traffic surge on outdoor pollutant measurement using Zaria, northern Nigeria, as a case study. The study collected a 1-year time-serie...

The need for proper solid waste management cannot be overemphasised. This study thus, analysed the sites suitable for waste disposal in Kaduna South Local Government Area (LGA) with a view to provide adequate information for better management of solid wastes. This was achieved through understanding the land use dynamics and the mapping of the exist...

Flood occurrences are common in various communities and efforts need to be doubled to abate the effect of flood on the populace. This paper used Multi-Criteria Analysis (MCA) in a Geospatial Information System (GIS) environment to identify and map areas vulnerable to flood in Fagge Local Government Area of Kano State. The causative factors of flood...

The dwindling arable land and diminishing role of key institutional support measures have contributed greatly to the low farm productivity witnessed in recent times. Geospatial technology was utilized to design a farm information system for selected regions of Zaria and environs. Results revealed key drivers for improved and sustained farmland prod...

This study explored the use of geospatial methods in analysing the health- care facilities in Sabon-Gari Local Government Area of Kaduna State. Locational information on health care facilities were obtained using an Etrex® H hand-held Global Positioning System (GPS). A Bing image was obtained from SAS Planet Release 160707, georeferenced and digit...

This study aims at mapping the temporal variability of absolute dynamic topography in parts of the Central Atlantic using multi-mission satellite altimetry data for marine and climate change modeling and action plan in the study area.
