El aprovechamiento de los pastos por parte de los animales en régimen de ganadería extensiva hace que éstos pasen gran parte del tiempo, si no todo, al aire libre, quedando expuestos a ataques por parte de la fauna salvaje. En España, la mayor preocupación al respecto lo genera el lobo ibérico (Canis lupus signatus), que tiene poblaciones estables y densas especialmente en el noroeste de la Península Ibérica en las comunidades autónomas de Castilla y León, Galicia, Principado de Asturias y Cantabria, y con tendencia creciente. Los casi 3.000 lobos —algo menos de 300 manadas— que se estima que actualmente viven en España causan daños a unas 10.000 cabezas de ganado al año, lo que supone una cantidad anual de 3,5 millones de euros para compensar los daños y más de 4 millones para implementar medidas preventivas

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.
