This would involve the estimation of indirect and non-use wetland values, and the examination of linkages between water flow regimes and wetland values, using bioeconomic modelling. Key words: Mekong River Delta, wetland management, economic valuation, direct use values. APPENDIX 2 Potential Economic Value of Western and Central African Basins primary objective of producing a review of river fisheries valuation in this region (as a contribution to the Water, Ecosystems and Fisheries Review Workshop, organised by the World Fish Center, Phnom Penh, 15 .   Valuation of fish production services in river basins: a case study of the Columbia River This study uses a bio-economic model to assess the capacity of the Columbia River to provide a selection of four ecosystem services and estimates the use of those services in terms of net economic welfare.   Parks and Wildlife recognises that the potential impacts of climate change will alter the ecological function of the Swan and Canning rivers and the way people interact with them. Rising water levels, changes in biodiversity and reduced stream flow are among the impacts of climate change predicted for the Swan Canning Riverpark.
