Urbanization against ecologically sensitive areas: effects of land use activities on surface water bodies in the Kumasi Metropolis

Abstract

ABSTRACT The increase in human activities in urban areas resulting from the urbanisation process continues to put immense pressure on urban ecological resources including water bodies. This study seeks to assess the relationship between the various categories of human activities within the 100 m buffer of the major water bodies in the Kumasi Metropolis and the chemical and biological composition of the pollutants that are emitted into the water bodies. The findings of this study showed that the Kumasi Metropolis is confronted with weak enforcement of regulations that protect water bodies. For example, along the Subin River, human activities such as commercial activities and the development of squatter settlements did not conform to the standard setback average distance of 100 feet in the Zoning Regulation and Planning Standards. There is a need for city authorities to strategically respond to the various human activities that threaten the sustainability of water resources in cities.
