2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
Los cultivos en terrazas son una técnica agrícola de manejo y conservación del suelo originaria de los pueblos andinos. Consiste en cortar el perfil de una pendiente (paisaje montañoso) de manera escalonada para, en el suelo horizontal resultante, sembrar (hortalizas, arbustos o arboles) y cultivar especies agrodiversas que se den en la zona.
2.2 Detailed description of the Technology
Description:
Esta tecnología consiste en la siembra de pastos o arbustos en hileras que tienen la característica de tener las raíces profundas que les permiten sostener la tierra que se desliza por la pendiente y labores culturales que realizan en el terreno, las hileras de pastos o arbustos deben ser sembradas con curvas de nivel con un distanciamiento desde los 5 hasta los 20 m dependiendo de la pendiente. La erosión de los suelos es considerada uno de los problemas ambientales más significativos del sector rural, asimismo, dicha problemática está asociada a una disminución de la productividad y eficiencia de los suelos, provocada por una baja retención tanto del agua como del suelo, cuya tendencia a escurrir se manifiesta en mayor medida en terrenos con pendientes pronunciadas. La incorporación de las técnicas de conservación de aguas y suelos demanda un importante esfuerzo técnico y económico, por lo que los conocimientos referentes a esta temática y los estudios que se han realizado al respecto, son escasos. Este esfuerzo, está dirigido a pequeños propietarios agrícolas y forestales de sectores semiáridos de nuestro país, y que tiene por objetivo el ofrecer nuevas tecnologías de conservación de aguas y suelos, que permitan actuaciones más acordes con el medio ambiente físico y social y que hagan posible acercarse hacia un desarrollo sostenible.
