En algunas zonas del sudeste español durante el siglo XX existió una industria significante y dinámica basada en el empleo del cáñamo y del esparto que apoyaba la economía rural. Hoy día esta industria prácticamente ha desaparecido, lo que ha incentivado la desertificación en algunas localidades y la despoblación. Hoy día el interés de la industria por el uso de fibras naturales como refuerzo en los últimos años ha abierto nuevas expectativas para el sector. Son diversas las empresas automovilísticas que están ya incorporando composites con fibra natural en su cadena productiva. Así por ejemplo ocurre con el abacá, o fibra de cáñamo de Manila, que ya ha sido y sigue siendo empleada por una compañía automovilística, con un procedimiento de producción patentado. De la misma forma, en los Estados Unidos varias empresas ya incorporan algunos componentes con bio-composite de cáñamo. De esta forma se abren nuevas oportunidades de trabajo en el ámbito rural, así como en el sector de la industria y la construcción.

Agricultural run-off and subsurface drainage tiles transport a significant amount of nitrogen and phosphorus leached after fertilization. alchemia-nova GmbH in collaboration with University of Natural Resources and Life Sciences, Vienna developed two multi-layer vertical filter systems to address the agricultural run-off issue, which has been installed on the slope of an agricultural field in Mistelbach, Austria. While another multi-layer addressing subsurface drainage water is implemented in Gleisdorf, Austria. The goal is to develop a drainage filter system to retain water and nutrients. Both multi-layer filter systems contain biochar and other substrates with adsorption properties of nutrients (nitrogen, phosphorus). The filter system can be of practical use if an excess of nutrients being washed out is of concern in the fields of the practitioner by keeping the surrounding waters clean. This approach may result in economic value by re-using the saturated biochar as fertilizer and improving the soil structure, thus increasing long-term soil fertility.

FACTSHEET NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY Key information Functionalized nanocellulose membranes can take up nitrate and phosphate. These membranes can be put in a water treatment unit. As the membranes are biobased, degradable materials, they can after use be added to the soil, thus returning the leached nutrients back for their original purpose providing fertilizers (nutrient recycling).
Because variables such as temperature and humidity have a profound effect on the activity of crop pests, diseases and natural enemies, the ability to monitor environmental conditions within a crop has always been important for crop protection.
