La quantità di dati per lo sviluppo è abbastanza?

NAIROBI – I rapidi progressi della tecnologia hanno abbassato drasticamente il costo della raccolta dei dati. I sensori nello spazio, il cielo, il laboratorio e il campo, insieme con la recente opportunità di crowdsourcing e l'adozione diffusa di Internet e dei cellulari, rendono disponibili grandi quantità di informazioni a quelli che in precedenza non avevano la possibilità di usufruirne. Un produttore su piccola scala nelle zone rurali dell'Africa, ad esempio, può ora accedere alle previsioni meteo e ai prezzi di mercato semplicemente toccando lo schermo.

Questa rivoluzione dei dati offre un enorme potenziale per migliorare il processo decisionale su tutti i livelli - dal contadino locale alle organizzazioni per lo sviluppo in tutto il mondo. Ma la raccolta di dati non è sufficiente. L'informazione deve essere gestita e valutata - e farlo correttamente può essere molto più complicato e costoso dello sforzo per raccoglierla. Se le decisioni da migliorare non sono subito individuate e analizzate adeguatamente, c'è un rischio elevato che gran parte dello sforzo di raccolta potrebbe essere sprecato o indirizzato male.

Tale conclusione è a sua volta basata sull'analisi empirica. La dimostrazione che le iniziative di monitoraggio in agricoltura o la gestione ambientale hanno avuto un impatto positivo è debole. L'analisi quantitativa delle decisioni attraverso molti ambiti, tra cui politica ambientale, investimenti delle imprese e sicurezza informatica, ha dimostrato che le persone tendono a sovrastimare la quantità di dati necessari a prendere una buona decisione o a fraintendere il tipo di dati che sono necessari.

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
