Tanzania-Zanzibar: Coastal Ecology and Natural Resource Management

Abstract

Beach erosion is a significant problem facing the coastlines of Zanzibar. This study addresses the current status of coastal erosion for the beaches of Paje and Nungwi, Unguja Island, Zanzibar. These sites were selected for their popularity as tourist destinations and likelihood of significant anthropogenic influence on shoreline change. Field observations were made and indicators of erosion were recorded during transects in both locations. Sediment samples were collected at fixed intervals along the transects and then analyzed statistically for grain size distribution trends at the Institute of Marine Science. Interviews were conducted with village residents to determine community response, and supplementary interviews were completed to gain greater comprehension of current legislation regarding coastal development. Study results show both beaches are undergoing significant erosion as a result of natural and anthropogenic forces. Recommendations were made for further studies on sediment transport, for increased monitoring of these and other beaches, and for greater enforcement of regulations by government officials.
