    Hydrologic-economic appraisal of life-cycle costs of inter-basin water transfer projects

    This article describes research that compares actual water transfers of an inter-basin transfer (IBT) scheme with its original, appraisal stage, prediction. Transfers are shown to be significantly less and also more variable than predicted. Further research reveals that the state of the receiving system has a large bearing on year-to-year decisions regarding water transfers. Past appraisals, following what is called the Incremental Approach, do not adequately consider the stochastic nature of the likely future inter-basin transfer operating regime. Examination of six case studies, four South African, one Chinese and one Australian, shows that the Incremental Approach is still in general use – despite tools available for an improved approach. A new approach, called the Comprehensive Approach, is proposed to upgrade estimations of variable costs associated with water transfers – often substantial life-cycle cost components of IBTs.A demonstration of the Comprehensive Approach, by means of an example of an IBT with significant pumping costs associated with water transfers, is provided. Uncertainty regarding future water transfers and associated variable costs are provided for by stochastic simulation  modelling. The Incremental Approach is shown to be severely biased with respect to variable costs and it is shown that this bias leads to significantly different estimations of likely life-cycle project costs. Such differences conceivably lead to suboptimal decision-making.Keywords: Water resources, inter-basin water transfer, project appraisal, life-cycle costs, stochastic modellin

    Unit Reference Value: Application in appraising inter-basin water transfer projects

    Unit Reference Value (URV) is a common measure in South Africa to assess the economic efficiency of proposed water projects. This is a companion article to an earlier one establishing that the current approach of appraisal of inter-basin water transfer projects (IBTs) with significant pumping costs overestimates likely future water transfers and thereby variable operational costs. Those findings are taken further and it is established that the URV, as currently applied, fails as a suitable measure to appraise such IBTs. From rooting URVs in fundamental cost effectiveness analysis theory a revised URV approach is proposed that provides for a conceptual separation between water transfers affecting operating costs and water transfers used as a proxy measure for effectiveness. The prominent effect of the revised URV approach is demonstrated by means of the example of the proposed Thukela Water Project in South Africa.Keywords: unit reference value, cost effectiveness analysis, inter-basin water transfers, project appraisa

    Abu Ghraib and the War against Terror - a case against Donald Rumsfeld

    The pictures of the inhuman and abusive treatment of Iraqi prisoners at the Abu Ghraib prison shocked the world. The authors of this contribution will take a criminological approach to the crimes committed and will show—by using an analytical framework used by organizational criminologists—that the abuse and torture at Abu Ghraib was an inevitable outcome of the War on Terror as launched by the U.S. administration in a reaction to the terrorist attack launched against it. The abuse at Abu Ghraib which violated U.S. as well as international human rights law was not caused by a few rotten apples as policymakers tried to make us believe, but was a clear example of a state crime. A state crime for which U.S. leaders within the Bush administration such as the Secretary of Defense Donald Rumsfeld, might be held criminally responsible if they would be prosecuted by the ICC
