Salvar los peces del mundo

Resulta difícil no sentir pesimismo respecto del futuro de la población piscícola del mundo. Las capturas marinas mundiales, que habían aumentado rápidamente a partir de la segunda guerra mundial, dejaron de hacerlo al final del decenio de 1980 y desde entonces no han dejado de disminuir. Será difícil detener ese descenso.

La rápida reducción de las poblaciones de peces es el resultado inevitable de una refinada tecnología industrial empleada con poblaciones marinas que están menguando, a medida que aumenta la demanda, avivada por el crecimiento de la población y la renta humanas. Hasta ahora ese descenso ha quedado oculto en el mundo desarrollado gracias a productos alimenticios marinos antes no disponibles, como, por ejemplo, el salmón criado con acuicultura, e importaciones en gran escala de pescado procedente de países en desarrollo.

Pero la pesca excesiva ha llegado a ser un problema grave también en el mundo en desarrollo. Así, pues, en un futuro próximo a las pesquerías de todo el mundo les esperan cambios drásticos. Un indicio claro del problema es ``la pesca de los elementos inferiores de la cadena alimentaria marina'': la tendencia cada vez más frecuente a pescar peces y mariscos del fondo de las cadenas alimentarias marinas, con frecuencia presa de los peces mayores, que antes eran objeto de la pesca,

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California.

    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.
