Cooperación tecnológica

A principios de febrero, la Academia Nacional de Ingeniería de Estados Unidos publicó un informe sobre los “Grandes retos para la ingeniería en el siglo XXI”. Su objetivo es centrar la atención en el potencial de la tecnología para ayudar al mundo a encarar la pobreza y las amenazas ambientales. Esta lista incluye innovaciones potenciales como la energía solar de bajo costo, la eliminación segura del CO2 de las plantas de energía, la fusión nuclear, nuevas tecnologías educativas y el control de los efectos secundarios ambientales de los fertilizantes nitrogenados. El informe, similar a la lista de la Fundación Gates sobre “Grandes retos” en materia de salud global, resalta una nueva prioridad mundial: promover tecnologías avanzadas para el desarrollo sostenible.

Estamos acostumbrados a pensar sobre la cooperación global en campos como la política monetaria, el control de enfermedades o la proliferación de las armas nucleares. No estamos tan acostumbrados a pensar en la cooperación global para la promoción de nuevas tecnologías como la energía limpia, una vacuna contra la malaria o cultivos resistentes a las sequías para ayudar a los campesinos pobres de África. En gran medida, consideramos que las nuevas tecnologías son algo que deben desarrollar las empresas para el mercado, y no oportunidades para resolver problemas globales.

Sin embargo, dadas las enormes presiones globales a las que nos enfrentamos, incluyendo las grandes desigualdades en los ingresos y el inmenso daño ambiental, debemos encontrar nuevas soluciones tecnológicas a nuestros problemas. Por ejemplo, no hay manera de seguir ampliando el uso global de la energía en forma segura a menos que cambiemos drásticamente nuestra forma de producir electricidad, de propulsar nuestros automóviles y de calentar y enfriar nuestros edificios. Recurrir al carbón, el gas natural y el petróleo sin pensar en las emisiones de CO2, como lo hacemos actualmente, es sencillamente demasiado peligroso porque está provocando cambios climáticos que propagarán enfermedades, destruirán cultivos, producirán más sequías e inundaciones y tal vez elevarán espectacularmente el nivel del mar, inundando así las zonas costeras.

    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.

    Rage Against the Elites

    • Taken together, they help us to understand what that moment is and how it arrived, while reminding us that history is contingent, not inevitable

    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.
