¿Cómo alimentar a una sociedad imperfecta?

STANFORD/BERKELEY – Casi todos en la comunidad científica coinciden en que garantizar una provisión de alimentos suficiente para una población humana cada vez más numerosa, que a mediados de siglo habrá sumado otros 2500 millones de personas, será tarea ardua. Todavía no hemos sido capaces de hacerlo con los 7300 millones de personas de la actualidad: casi 800 millones sufren desnutrición o hambre, y otros dos mil millones no obtienen micronutrientes suficientes. Pero respecto de cómo encarar el problema de la seguridad alimentaria, no hay un consenso similar.

La comunidad científica está dividida entre dos grandes líneas de acción: “hacer ajustes a la producción agrícola” o “reformar las bases de la sociedad”. Los partidarios de la primera estrategia son clara mayoría, pero la segunda es más convincente.

Es verdad que el campo de los ajustes ha identificado muchos problemas importantes en los sistemas actuales de producción y distribución de alimentos, cuya solución puede mejorar la seguridad alimentaria. Desarrollar mejores variedades de cultivo para aumentar la productividad agrícola. Hacer un uso más eficiente del agua, de los fertilizantes y de los pesticidas. Proteger los bosques tropicales y otros ecosistemas relativamente vírgenes, para preservar servicios cruciales de la naturaleza, especialmente los relativos a la fertilidad del suelo, la polinización, el control de plagas y el mejoramiento climático. Revertir la tendencia actual hacia un mayor consumo de carne. Regular más estrictamente la actividad pesquera y la contaminación oceánica para mantener las fuentes de proteína marina de las que mucha gente depende. Reducir el derroche en la producción y distribución de alimentos. Enseñar a las personas a elegir alimentos más nutritivos y de producción más sostenible.

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
