Abstract: This research examines the geographical spread of gas-related pollutants, particulate matter, and climatic influences linked to gas flaring in Alesa Eleme, Rivers State, Nigeria. A methodology combining environmental observation, survey information, and statistical evaluation was utilized. Air quality assessments were carried out at five distances (0.5–2.5 km) from the flaring locations using portable monitoring devices, while weather data were recorded concurrently. The sample included 399 individuals chosen via stratified random sampling, alongside 91....

Abstract: Increased construction and infrastructure development in Ghana has meant increased C&DW, posing challenges to urban sustainability. Although the circular economy is increasingly acknowledged, in C&DW, there is scant practical applicability and regulation in many cities of Ghana. This research addressed the management of C&DW in Wa Municipality, Upper West Region, Ghana. This included the reuse of C&DW, the drivers of C&DW, constraints on the use of C&DW, the knowledge of infrastructure development regulations, and the barriers to the protection....
