Con la escasez de alimentos impulsada por la caída de las capas freáticas, la erosión de los suelos y el aumento de las temperaturas, el control de la tierra cultivable y los recursos hídricos se están convirtiendo en el centro de la lucha mundial por la seguridad alimentaria. “En esta era de difícil acceso a los suministros alimentarios mundiales, la capacidad de cultivar alimentos se está convirtiendo rápidamente en una nueva forma de apalancamiento geopolítico. La comida es el nuevo petróleo”, escribe Lester R. Brown. ¿Cómo se verá la geopolítica de los alimentos en una...

Following the overthrow of the classical world picture by the findings of quantum mechanics, physicists have proposed a broad gamut of alternative worldviews. The Quantum Enigma begins with the major recognition that each of these suffers from a certain residual Cartesianism that has been smuggled in unconsciously. It turns out that the moment this hidden and problematic premise is discarded, quantum theory begins to make sense in a way that it never has before. As the author shows, it is now possible, for the first time, to integrate the findings of quantum physics into a worldview that...

(Complete work in Spanish) Remote sensing aerial spectral imaging was one of the first application areas where spectral imaging was used in order to identify and monitor the natural resources and covers on earth surface. Aerial spectral imaging is being developed with the aim of monitoring natural resources like coastal areas, forestry and extensive crops. The information contained in hyperspectral images allows the reconstruction of the energy curve radiated by the terrestrial surface throughout the electromagnetic spectrum. Hence, the characterization, identification and classification of...
