LEE, Deborah E e DU PREEZ, Mario. A demand-based management option to address boat congestion at the Sundays River Estuary, Eastern Cape, South Africa. Water SA [online]. 2015, vol.41, n.4, pp. 579-585. ISSN 0378-4738. http://dx.doi.org/10.4314/WSA.V41I4.18.
The Sundays River Estuary situated in the Eastern Cape is an example of a South African Estuary experiencing congestion externalities, mainly vis-à-vis motorised boat use. This paper employs a choice model to estimate people's preferences for less boat congestion on the Sundays River Estuary. The results show that visitors to the estuary are willing to trade off a levy of ZAR 35/a (in addition to what they already pay) for a reduction of boat congestion during peak periods (only). This paper proposes that this amount be set as a user charge to manage excess recreational boat use.
