The Right of Access to Water in the Context of Investment Disputes in Argentina: Urbaser and Beyond

To this end, four Argentinian investment water disputes 'Azurix v. Argentina, AWG v. Argentina, Impregio v. Argentina and Urbaser v. Argentina' concluded in the last 20 years are subjected to a comparative analysis.
