Spatial analysis of the effects of urban expansion on agricultural land use in sub-Saharan Africa: A case of Dar es Salaam region in Tanzania

Abstract

This study aimed to analyze the effect of urban expansion on agricultural land use in Dar es Salaam. It involved Classification of Sentinel-2 Satellite Imagery to ascertain whether there was a change in land use/land cover for the time period 2016 until 2019 using maximum likelihood algorithm. The classification accuracy was 62% and Kappa Hat coefficient 0.48 for 2016 and 79.15% and Kappa Coefficient 0.75 for 2019 respectively. A total of 17,428.06 hectares of land were detected to have changed from other classes into Urban and built-up.
