Water. World Water, A Crisis Of Global Governance?, Robert Weiner
Water. World Water, A Crisis Of Global Governance?, Robert Weiner
New England Journal of Public Policy
In a global world, how can water, a necessary and increasingly scarce resource, be managed? We understand that water is a basic need. Do we also share the belief that water is a basic right? Does the international community share beliefs about water that may be the foundation of an international regime or system of global governance for the equitable implementation of global water policy? And finally, what international body or bodies might handle the disputes that arise as our population and need for water increase? The author tackles these questions and looks at models to guide us.

IFPRI and IWMI's report uses computer modeling to project water demand and availability through to 2025 and predicts the likely impact of changes in water policy and investment, making specific recommendations for specific locations around the globe. The report argues that if current water policies continue, farmers will find it difficult to meet the world’s food needs. Hardest hit will be the world’s poorest people. The authors call for: International commitment to sustainable use of water, through appropriate policies and investments; Wider application of existing water saving technologies; The removal of inappropriate incentives and reform of institutions which hinder effective …

Water. The Geopolitics Of Water, Paul Michael Wihbey, Ilan Berman
Water. The Geopolitics Of Water, Paul Michael Wihbey, Ilan Berman
New England Journal of Public Policy
In the great geo-strategic game known as the Middle East, peace politics get much of the press and the attention of policy leaders. On occasion, oil takes center stage but often for the wrong reason (see, e.g., "The End of the Oil Era and the Price of Oil"). What is important to understand is that water is in fact the key strategic resource in the region and if you follow the flow of water, you'll follow the politics and policy machinations that lie at the heart of the Israeli-Syrian dialogue. IASPS Fellow in Strategy Paul Michael Wihbey co-authored an analysis …

The use of chemically modified XAD-4-1,2-bis (o-aminophenylthio) ethane chelating resin for preconcentrating Cr^{6+}, Mn^{2+}, Fe^{3+}, Co^{2+}, Cu^{2+}, Cd^{2+}, Zn^{2+}, Pb^{2+}, and Ni^{2+} was studied using flame atomic absorption spectrometry (FAAS) for metal monitoring in environmental samples. Cd^{2+}, Zn^{2+}, Pb^{2+}, and Ni^{2+} ions were quantitatively recovered at the rate of 96.0%, 101.0%, 101.0%, and 95.0%, respectively (RSD < 5%), from the studied solutions. The procedure is based on the retention of analytes on a short column of 1,2-bis (o-aminophenylthio) ethane-XAD-4 chelating resin from a buffered sample solution and subsequent elution with 1 M HNO_3. Various parameters, such as pH, eluent type, and concentration, flow rate of sample solution and matrix interference effect on the retention of the metal ions have been studied. The optimum pH for the sorption of the above-mentioned metal ions was about 6. The adsorption and batch capacity of adsorbent and loading half time (t_{1/2}) for Ni^{2+}, Zn^{2+}, Cd^{2+}, and Pb^{2+} were established. The limit of detection was 3.0 \mu g L^{-1} for Pb^{2+} and Ni^{2+}, 0.6 \mu g L^{-1} for Cd^{2+}, and 0.3 \mu g L^{-1} for Zn^{2+}. The validation of the procedure was carried out by analysis of certified reference materials and standard addition. The proposed enrichment method was applied to environmental samples from Trabzon.
