    Abstract: As a result of diversion of upstream waters and intensive mineral extraction along its shores, the level of the Dead Sea is dropping at a rate of almost one meter per year, causing the sea continuously to break its own record as the lowest place on earth. The loss of the sea and the accompanying ecological and cultural damage in the basin has traditionally been regarded as an unavoidable consequence of rational economic policy. This study investigates for the first time the non-market economic value of conservation of the Dead Sea basin using both contingent valuation (stated preference) and travel cost (revealed preference) studies. Study results indicate that all three local populations, Israeli, Jordanian and Palestinian, demonstrate a substantial willingness to pay to preserve the cultural and environmental heritage of the region. Such results strengthen the case for conservation of the region, which, heretofore, has relied strictly on ethical and ecological rationales.

    The Polluter Pays Principle as a policy tool in an externality model for nitrogen fertilizer pollution
    IWA Publishing ; 2012

    Abstract: A policy based on the Polluter Pays Principle (PPP) with respect to the subject of contamination by nitrogen fertilizer is proposed. The mechanism is tested via a cost-efficient input tax policy to supply clean drinking water that is subject to contamination by nitrogen fertilizer and to quantify the welfare change due to public control. The paper proposes, for different water scarcity conditions, a policy that supports the legal principle of the PPP, by compensating the victim for the residual pollution not abated by the cost efficient solution, without any effects on the efficiency criterion. By introducing a Welfare Change Index (WCI) which measures the significance of an authority's intervention in dealing with externalities, we suggest that for relatively high and moderate water scarcity conditions, welfare change supports public intervention. However, for low scarcity conditions, welfare change is low, which discourages public intervention.

    Cost–benefit analysis of restoring an ephemeral desert stream after an ecological accident

    Abstract: This paper presents a methodology for examining the net benefit of site rehabilitation after an ecological disaster. While restoration of the site seems reasonable on the face of it, the cost of proactive restoration can be very high. In this article, we present a tool for decision makers to decide on the optimal route to rehabilitation – proactive or natural rehabilitation (or some combination thereof). We present a case study of an ecological catastrophe that occurred in June 2017 at an ephemeral desert stream in the south of Israel. We estimated the restoration costs and the benefits of restoration over the relevant time frame using a contingent valuation method. Comparing the present costs and benefits revealed a net present value of ILS 355.5 million in favor of proactive restoration of the stream. We also demonstrate that not all sections of the stream pass the benefit cost test, so a higher net benefit could be achieved through partial restoration. Our study demonstrates the importance of cost–benefit analysis when policy makers are contemplating proactive versus natural restoration.
