Reconstruction of the aquifer history of Gran Canaria

[EN]A study on the recent history and current state of the aquifer in the Island of Gran Canaria (Canary Is., 28oN, 15oW) is performed. Though rainfall is scarce on the island, traditional agricultural practices and small population were able to keep the aquifer in a constant state for centuries. Nevertheless, at the beginning of the 20th Century, culture of several water-consuming species was introduced on a commercial basis due to the relative proximity of the Canaries to continental Europe and to the possibility of more than one yearly harvest. This led to generalised well digging (more than 300m deep in many cases) and to the appearance of a chronic hydraulic deficit, as well as to spoiling vastcoastal areas of the aquifer through intrusion of brackish water. In the mid 1960’s, coincident with the apex of agricultural exploitation, massive tourism appeared in the scene. This new activity soon became a susbstitute for Agriculture, but it attracted more new labour force to the island, and a fast growth of population was the main result. Moreover, new water use practices entered the scene. As a consequence, the main causes for the aquifer decline are population growth and extensive Agriculture practices in use during the last half of the 20th Century. Some remarks on sustainability issues in order to cope with Climate Change are also offered.

Las lenguas de extremo oriente y el español: los diccionarios y gramáticas como primeros instrumentos para la comunicación en Filipinas y China

[ES]En este trabajo mostraremos cómo desde los inicios de la Edad Moderna la lexicografía española se constituyó en uno de los vínculos que unían Europa, América y el Extremo Oriente. La modernización de la lexicografía en el continente europeo vino de la mano de Nebrija. Y, así, las nuevas gramáticas y diccionarios escritos para favorecer la comunicación entre los españoles y los pueblos del Extremo Oriente (Filipinas y China) llevaron más allá de las fronteras de España el modelo de Nebrija. Asimismo, ofrecemos un panorama de estas obras desde el siglo XVI hasta comienzos del siglo XX.
