Zachraňte naši půdu

BERLÍN – Organizace spojených národů vyhlásila rok 2015 Mezinárodním rokem půdy a ve dnech 19. až 23. dubna si připomínáme letošní Celosvětový týden půdy. Tyto události nemají velký lesk, ale přesto by si zasloužily mnohem větší pozornost.

Nedotčené půdy představují neocenitelný a nenahraditelný zdroj, který při zajišťování hlavních rozvojových a ekologických cílů mezinárodního společenství plní bezpočet funkcí. A dnes tyto půdy naléhavě potřebují ochranu.

Zdravá půda je stěžejním předpokladem lidské výživy a boje proti hladu. Spoléháme na ni nejen při produkci potravin, ale i při vytváření nových zdrojů pitné vody. Pomáhá regulovat klima na zeměkouli, váže více uhlíku než všechny světové lesy a pralesy dohromady (pouze oceány jsou větší zásobárnou uhlíku) a je nezbytná pro zachování biodiverzity: hrst úrodné půdy obsahuje více mikroorganismů, než kolik žije na planetě lidí. Dvě třetiny druhů na zeměkouli žijí pod jejím povrchem.

    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

    • With the advantage of hindsight, four recent books bring to bear diverse perspectives on the West’s current populist moment. 
    • 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.
