Abstract: | The basin scale has been promoted universally as the optimal management unit that allows for the internalization of all external
effects caused by multiple water uses. However, the basin scale has been put forward largely on the basis of experience in
temperate zones. Hence whether the basin scale is the best scale for management in other settings remains questionable. To
address these questions this paper analyzes the economic viability and the political feasibility of alternative management
options in the Kidron/Wadi Nar region. The Kidron/Wadi Nar is a small basin in which wastewater from eastern Jerusalem flows
through the desert to the Dead Sea. Various options for managing these wastewater flows were analyzed ex ante on the basis
of both a cost benefit and a multi-criteria analysis. The paper finds that due to economies of scale, a pure basin approach
is not desirable from a physical and economic perspective. Furthermore, in terms of political feasibility, it seems that the
option which prompts the fewest objections from influential stakeholder groups in the two entities under the current asymmetrical
political setting is not a basin solution either, but a two plant solution based on an outsourcing arrangement. These findings
imply that the river basin management approach can not be considered the best management approach for the arid transboundary
case at hand, and hence is not unequivocally universally applicable. |
