“…Our study is similar to analyses by Paulsen and Wernstedt (1995) and Garber-Yonts and Rettig (1997), but we used more recent models of salmon populations, estimates of D, and estimates of recovery costs. We also assessed some measures (dam breaching, Caspian Tern removal) that were not included in their analyses.…”

The mandate to increase endangered salmon populations in the Columbia River Basin of North America has created a complex, controversial resource-management issue. We constructed an integrated assessment model as a tool for analyzing biological-economic trade-offs in recovery of Snake River spring- and summer-run chinook salmon (Oncorhynchus tshawytscha). We merged 3 frameworks: a salmon-passage model to predict migration and survival of smolts; an age-structured matrix model to predict long-term population growth rates of salmon stocks; and a cost-effectiveness analysis to determine a set of least-cost management alternatives for achieving particular population growth rates. We assessed 6 individual salmon-management measures and 76 management alternatives composed of one or more measures. To reflect uncertainty, results were derived for different assumptions of effectiveness of smolt transport around dams. Removal of an estuarine predator, the Caspian Tern (Sterna caspia), was cost-effective and generally increased long-term population growth rates regardless of transport effectiveness. Elimination of adult salmon harvest had a similar effect over a range of its cost estimates. The specific management alternatives in the cost-effective set depended on assumptions about transport effectiveness. On the basis of recent estimates of smolt transport effectiveness, alternatives that discontinued transportation or breached dams were prevalent in the cost-effective set, whereas alternatives that maximized transportation dominated if transport effectiveness was relatively high. More generally, the analysis eliminated 80-90% of management alternatives from the cost-effective set. Application of our results to salmon management is limited by data availability and model assumptions, but these limitations can help guide research that addresses critical uncertainties and information. Our results thus demonstrate that linking biology and economics through integrated models can provide valuable tools for science-based policy and management.

“…Most water management related cost-effectiveness studies are at river basin scale (Paulsen and Wernstedt, 1995;Cools et al, 2011) or at national scale (Schou et al, 2000;Brady, 2003;Hanley and Black, 2006) or even regional scale (Gren et al, 1997;Froschl et al, 2008). Such large scale analyses tend to fail to reflect the internal variability inherent in environmental systems.…”

This paper presents an application of integrated methodological approach for identifying cost-effective combinations of agri-environmental measures to achieve water quality targets. The methodological approach involves linking hydro-chemical modelling with economic costs of mitigation measures. The utility of the approach was explored for the River Dee catchment in North East Scotland, examining the cost-effectiveness of mitigation measures for nitrogen (N) and phosphorus (P) pollutants. In-stream nitrate concentration was modelled using the STREAM-N and phosphorus using INCA-P model. Both models were first run for baseline conditions and then their effectiveness for changes in land management was simulated. Costs were based on farm income foregone, capital and operational expenditures. The costs and effects data were integrated using 'Risk Solver Platform' optimization in excel to produce the most cost-effective combination of measures by which target nutrient reductions could be attained at a minimum economic cost. The analysis identified different combination of measures as most cost-effective for the two pollutants. An important aspect of this paper is integration of model-based effectiveness estimates with economic cost of measures for cost-effectiveness analysis of land and water management options. The methodological approach developed is not limited to the two pollutants and the selected agri-environmental measures considered in the paper; the approach can be adapted to the cost-effectiveness analysis of any catchment-scale environmental management options.

“…Booth (1989) studies the loss of salmon as a result of hydropower development in the Columbia River, where a steady stream of benefits in the form of increased electricity production has an increasing long-run cost in the form of lost fishing and reduced biodiversity. Paulsen and Wernstedt (1995) study subsequent measures in the same river sys tem which lead to losses of electricity but aim to improve salmon populations. Huang (1997) studies how changes in water pollution affect eel farming in Taiwan.…”

The Value of the Swedish Eel Fishery

Traditional sectors, such as agriculture and fishing, often receive special treatment from policymakers be cause such sectors are perceived to be associated with traditional cultural public good values. However, these values are often difficult to measure, and few attempts have been made to do so. The recent Euro pean Union (EU) eel management directive creates an unusually clear-cut tradeoff between eel fishing and other agents affecting the European eel population. It is possible, therefore, to directly measure the per ceived public good value of the eel fishery in terms of other economic costs that policymakers are willing to incur in order to maintain eel fishing. Using Swedish data, we find that Swedish policymakers value the public good aspect of the remaining Swedish eel fishery at a minimum of SEK 34 million (approximately EUR 3.4 million) annually, which is more than the commercial eel fishery's actual production value.
