El precio de salvar un árbol

América Latina cuenta con una proporción más que importante de vida silvestre y bosques de todo tipo. Un tercio de las especies de mamíferos y más de un cuarto de todas las especies de aves y reptiles conocidas se pueden encontrar allí. Sin embargo, esta abundancia está en peligro. Al hacer desaparecer más de siete millones de hectáreas de árboles por año, Sudamérica elimina más bosques que ningún otro continente. Como resultado, más de 10 000 especies están en peligro de extinción, dos tercios de todas las especies en peligro del planeta.

En cierto sentido, la solución a este reto es clara como el día. Los propietarios de tierras eliminan árboles porque es lo que les reporta más beneficios económicos, de manera que las autoridades deben darles incentivos para que no lo hagan. Si pudiéramos aprovechar el potencial oculto de los bosques de América Latina –sin destruirlos- podríamos dar una solución al problema de la destrucción de hábitats.

Podemos calcular fácilmente los costes de iniciativas conservacionistas individuales como el salvar la lechuza moteada del norte. Más difícil es calcular cuánto costaría hacer que los dueños de tierras dejen de talar sus árboles, pero eso no significa que no se haya intentado. Las estimaciones de los economistas varían de US$ 1,23 mil millones al año (para salvar árboles en los lugares con mayor diversidad de América Latina) a US$ 5,8 mil millones al año (para salvar un 2% del área terrestre del continente), e incluso a US$ 500 mil millones (hacer un solo pago para salvar todos los bosques de América Latina).

    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.
