Il valore dell’acqua

SINGAPORE/ATLANTA – All’inizio del diciannovesimo secolo, Lord Byron scrisse nel Don Giovanni che “Poco avvezzi alla sua privazione, gli uomini non sanno di qual prezzo sia un po’ d’acqua dolce”. Quasi 200 anni dopo, l’umanità non sembra aver ancora appreso il valore dell’acqua, esemplificato in decenni di scarsa gestione idrica praticamente ovunque. Ma ora nessuno può ignorare l’imminente crisi idrica – soprattutto chi ne sta già assaporando gli effetti.

Alcuni miglioramenti nella gestione idrica sono stati fatti negli ultimi anni. Ma sono stati raggiunti per gradi, a un passo troppo lento per affrontare il problema in modo efficace.

Per partire con il piede giusto, le grandi multinazionali come Nestlé, Coca-Cola, SABMiller e Unilever – che hanno a lungo rimarcato agli investitori la sfida posta dalla scarsità idrica per le loro attività, per non menzionare le comunità in cui operano – stanno lavorando per migliorare la reperibilità, la qualità e la sostenibilità dell’acqua. Il loro successo richiederà una strategia innovativa che ribalta le attuali ipotesi – e gli approcci – sui problemi dell’acqua.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.
