Eine neue Chance für arme Bauern

NEW YORK: Viele arme, Lebensmittel importierende Länder weltweit verzweifelten in den vergangenen Monaten angesichts der Verdoppelung der Weltmarktpreise für Reis, Weizen und Mais. Hunderte von Millionen armer Menschen, die bereits vorher einen Großteil ihres täglichen Budgets für Nahrungsmittel ausgegeben haben, werden an den Grenzen des Erträglichen gedrückt. Hungeraufstände nehmen zu. 

Dabei könnten viele arme Länder selbst mehr Nahrungsmittel anbauen, denn ihre Bauern produzieren viel weniger, als technisch möglich wäre. In einigen Fällen könnten sie – wenn ihre Regierungen die entsprechenden Maßnahmen ergreifen würden – die Lebensmittelproduktion in nur wenigen Jahren verdoppeln oder gar verdreifachen.

Die Idee ist einfach und allgemein bekannt. Die herkömmliche Landwirtschaft ist eine Low-Input-Landwirtschaft und erzielt schlechte Erträge. Die armen Bauern verwenden ihre eigene Saat der vorhergehenden Saison; es fehlt ihnen an Dünger; sie sind von Niederschlägen abhängig, statt zu bewässern, und nutzen – abgesehen von ihren traditionellen Hacken – kaum mechanische Geräte. Ihre Höfe sind klein: vielleicht ein Hektar oder weniger.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian Government’s Failed Campaign of Lies

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
