Botswana like many other developing countries has a challenge of identifying solid waste disposal sites and how to manage them properly. The challenge is worse in urban areas characterised by high population levels, rapid economic growth and rises in living standards of urban communities. All these challenges accelerate the generation of solid waste. The greater Gaborone region has a single landfill for solid waste near Gamodubu village in the Kweneng District. This study argues that the landfill was not properly sited. Hence, the motivation to conduct a comprehensive study to investigate if the Landfill was properly sited through the application of Geographic Information Systems (GIS) and Analytical Hierarchy Process (AHP) technologies. Prior to that, research on the current solid waste management practices in Gaborone and its environs will be conducted. GIS and Remote Sensing (RS) techniques will then be applied for environmental monitoring of leachate and land surface temperature (LST) from solid waste at the Gamodubu landfill, whose studies are currently non-existent in the region. Lastly, research on the factors influencing receptivity regarding waste sorting in Gaborone will be conducted. This study will demonstrate that GIS and RS techniques can be efficient and low-cost tools to provide optimal solutions for properly managing and monitoring urban solid waste, facilitate informed decision-making and improve environmental sustainability in the Greater Gaborone region.
