Elevar la sostenibilidad de las inversiones hídricas

NUEVA YORK – Desde que la ONU adoptara en 2000 los Objetivos de Desarrollo del Milenio (ODM), la comunidad mundial ha prestado gran atención a hacer posible el acceso a los servicios básicos de aguas y saneamiento, y con razón. Entre 1990 y 2010, más de dos mil millones de personas obtuvieron acceso a mejores fuentes de agua. En momentos que la ONU se prepara para adoptar los llamados Objetivos de Desarrollo Sostenible (ODS), como sucesores tras 2015 de los ODM, debería adquirir mucho más protagonismo el importante tema de la infraestructura hídrica a gran escala.

Normalmente se piensa que para mejorar el acceso al agua es necesario cavar pozos, tomar decisiones a nivel comunitario y centrar los programas de ayuda en llegar a más gente. Pero estas medidas importantes son solamente parte de una estrategia mucho mayor y para la que es necesario invertir mucho más.

De acuerdo con un informe reciente realizado por la UNICEF y la Organización Mundial de la Salud sobre su programa conjunto de monitoreo de los servicios de aguas y saneamiento, más de 1,2 mil millones de las personas que habían obtenido acceso entre 1990 y 2008 lo habían hecho conectando tuberías a una de sus instalaciones. Esta cifra empequeñece el impacto de las fuentes de “pequeña escala” (desde cavar pozos a recoger agua de lluvia) que muchos creen han sido las más importantes para solucionar el problema.

    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.
