ENGLISH SUMMARY: Estuaries are among the most productive and biologically diverse ecosystems on Earth. They provide important ecosystem services, such as nutrient cycling, water filtration, storm protection and are important habitats for a wide range of species. Estuaries also are important recreational areas. Despite their importance, estuaries face significant pressures from both natural and anthropogenic sources. Determining the economic value of the ecosystem services provided by estuaries can help resource managers make informed and effective decisions about their management. This thesis uses a choice experiment to determine the marginal economic value of the recreational service provided by the Kleinmond Estuary, located in the Overberg region of the Western Cape, South Africa. The aim of this study is to reveal recreational users’ preferences for improvements in open-water space and water quality in the Kleinmond Estuary to inform potential investment in and better management of the Kleinmond Estuary to ensure a sustained flow of benefits to the local community and the economy of the town. The results from the choice experiment reveal clear preferences among visitors to the Kleinmond Estuary. The willingness to pay (WTP) was highest for a significant increase in kayaking space (R156.43), followed by a WTP to avoid a moderate risk of water contamination (R144.04) and a WTP for a significant increase in views of the water (R105.81). An ordinal multinomial analysis also revealed a clear preference for scenarios with significant increases in space for kayaking. The thesis includes a comparative analysis of the estimated recreational value against the costs of implementing improvements, using net present value calculations over a 20-year period. This comparison provides insights into the economic feasibility and potential benefits of the management interventions presented in the study. Recommendations are made for future research, including conducting longitudinal studies to track changes in WTP over time, studying the ecological processes within the estuary and investigating the socio-economic factors influencing visitor preferences. Furthermore, the study discusses the need to develop and test financing mechanisms to fund the management interventions for increasing open water space and improving the water quality in the Kleinmond Estuary. AFRIKAANSE OPSOMMING: Riviermondings is een van die mees produktiewe en biologies diverse ekosisteme op aarde. Hulle verskaf belangrike ekosisteemdienste, soos voedingstofsiklusse, waterfiltrering en stormbeskerming en belangrike habitatte vir 'n wye verskeidenheid spesies. Riviermondings is ook belangrike ontspanningsgebiede. Ten spyte van hul belangrikheid, ondervind riviermondings aansienlike druk van beide natuurlike en antropogeniese bronne. Om die ekonomiese waarde van hierdie dienste te verstaan is noodsaaklik vir ingeligte besluitneming en effektiewe bestuur. Hierdie tesis ondersoek die ontspanningswaarde van die Kleinmond-riviermond, 'n gewilde riviermond in die Overberg-streek van die Wes-Kaap in Suid-Afrika. Die doel van hierdie studie is om ontspanningsgebruikers se voorkeure vir verbeterings in oopwaterruimte en watergehalte in die Kleinmondriviermond aan die lig te bring om potensiele belegging in en beter bestuur van die riviermonding in te lig om 'n volgehoue vloei van voordele vir die plaaslike gemeenskap en die ekonomie van die dorp. Die resultate van die keuse-eksperiment toon duidelike voorkeure onder besoekers aan die Kleinmondriviermond. Die bereidwilligheid om te betaal (WTP) vir 'n aansienlike toename in kajakruimte was R156.43 en die WTP vir aansienlik verbeterde uitsigte oor die water R105.81 in teenstelling met geringe verbeterings vir beide eienskappe. Respondente het 'n WTP van R144.04 om matige kontaminasierisiko te vermy, wat 'n voorkeur vir 'n lae kontaminasierisiko-scenario aandui. 'n Ordinale multinomiale analise toon ook 'n duidelike voorkeur vir scenario's met aansienlike kajakruimte. Die tesis sluit 'n vergelykende ontleding in van die beraamde ontspanningswaarde teen die koste van die implementering van verbeterings, deur gebruik te maak van netto huidige waarde (NHW) berekeninge oor 'n 20-jaar horison. Hierdie vergelyking verskaf insigte in die ekonomiese haalbaarheid en potensiele voordele van die bestuursintervensies wat in die studie aangebied word. Aanbevelings word gemaak vir toekomstige navorsing, insluitend die uitvoer van longitudinale studies om veranderinge in WTP oor tyd na te spoor, die ekologiese prosesse binne die riviermond in meer besonderhede te ondersoek en die sosio-ekonomiese faktore wat besoekers se voorkeure beinvloed, te ondersoek. Verder beklemtoon die studie die behoefte om finansieringsopsies vir riviermondbestuur te ontwikkel en te toets om volhoubare en doeltreffende bewaringspraktyke te verseker.
