“…Remote sensing and geographic information systems (GIS) are powerful tools that have been used to monitor and assess the changes in surface water bodies and wetlands [4]; [5]; [6]. Remote sensing is the science of acquiring data about the Earth's surface using sensors onboard satellites, aircraft, or drones [7]; [8]. The sensors detect and measure the electromagnetic radiation reflected or emitted from the Earth's surface, which is used to derive information about the land cover, land use, and changes in the environment [9]; [10].…”

This study aimed to use remote sensing and GIS to detect changes in surface water and wetlands in the Kumasi Metropolis over a period of 20 years (2002-2022). Landsat images were processed using the QGIS software, and the Maximum Likelihood Algorithm was used to perform supervised classification of land use land cover, while raster calculator aided in detecting wetlands by calculation for NDWI, MNDWI, and AWEI. The results showed that the majority of the landscape in the Kumasi metropolis was made up of built-up areas (79.4%), followed by agricultural lands (13.3%) and wetlands (7.3%). Over the 20-year period, built-up areas had gained 20.7% of the total landscape, while agricultural lands and wetlands had lost 16.7% and 4.0%, respectively. All water index methods recorded an increase in non-water cover and a loss of water cover over the period, with surface water decreasing by 5% and non-water land cover increasing by 5%. The study concludes that there have been significant changes in wetlands and surface water land use and land cover within the Kumasi Metropolis over the past 20 years, and recommends the enforcement of legislation on surface water protection in the area to protect wetlands
