Abstract
En este trabajo se explica la evolución en el desarrollo de la tecnología para la extracción del agua, desde mediados del siglo XIX hasta la llegada de las aguas del Trasvase Tajo-Segura en la década de los ochenta. Estos progresos en la moderniza-ción extractiva, fue de vital importancia para la supervivencia de la agricultura del Campo de Cartagena. Esta organizado intentando vincular la incorporación de las fuentes energéticas a los distintos sistemas de extracción. Así, estos los avances en la tecnología hidráulica han estado mediatizados por la potencia y la efectividad de los recursos energéticos: animales de tiro (motores de sangre), el viento, el carbón, el gas pobre, el aceite pesado, el gasoil, la gasolina y la electricidad. Su uso, determinó el tipo de máquina (motores y bombas extractoras de agua). Las inversiones por parte de los agricultores en estas máquinas fue de suma importancia para el aumento de la producción de la agricultura cartagenera. El merito es aun mayor al realizarse precisamente en un periodo donde la escasez de capitales podía bloquear la modernización del sector.
This paper describes the development of water extraction technologies, from the middle of the nineteenth century to the late twentieth century in the context of the Tajo-Segura Rivers water diversion and irrigation project. The progressive improvement of the water extraction process was very important for the survival of agriculture in Campo of Cartagena. This work is organized with the intention to link incorporation of power sources to several extraction technologies. The advances in new water extraction technologies were determined according to the power and the effi ciency of energy resources that were available: animal-power, wind, carbon, poor gas, heavy oil, gas-oil, gasoline and electricity. The farmers’ investments in these machines provided basic improvements in the region’s agriculture production. The signifi cance of these investments is all the more important given that during this period the shortage of capital could have blocked the modernization of the sector.
