Abstract: The main issue associated with groundwater supply in Botswana are the rate of its replenishment relative to its extraction rate and quality. This study aims to identify the possible causes and effects of groundwater decline at the Dukwi Wellfield. Specifically, it aims to investigate the contributing variables for groundwater decline at the wellfield area; the trend and significance of groundwater level decline using the linear trend model; the influence of groundwater decline...
