The development and implementation of a management plan for the Seekoei Estuary, South Africa: a case study guided by socio-economic issues
The large Temporarily Closed Seekoei Estuary has a long history of poor management. In 1969, a swimming pool complex was built in a position impinging on the mouth. The construction of a 500 m causeway across the lagoon connecting the residential townships of Paradise Beach and Aston Bay followed. F...
