La Conca de Tremp, situada en la comarca montañosa catalana del Pallars Jussá, es una de las áreas donde más se ha incrementado la ganadería porcina en régimen estabulado en las últimas tres décadas. Los impactos medioambientales negativos derivados de este sistema de producción ganadera son muy considerables, especialmente los relacionados con el vertido de puriñes que ha provocado un alto grado de nitrificación de las aguas. Análisis pormenorizados demuestran que el nivel de nitrificación de las aguas en la Conca de Tremp ha alcanzado un nivel muy alto, con las consecuencias que ello tiene en la salud de las personas. Atendiendo a las exigencias del desarrollo sostenible, única forma de garantizar el futuro de las comarcas de montaña, se apuntan soluciones para paliar los graves problemas generados por la intensificación de la ganadería porcina.
The Tremp Basin, placed in the mountainous Catalonian region of the Pallars Jussá, is one of the areas where stabled pig cattle raising has been more increased in the last three decades. Negative environmental impacts, derived from this cattle raising production system are greatly substantial, specially the ones related to purine wastes which have caused a high degree of nitrification of the waters. Detailed analyses show that the degree of nitrification of the waters in the Tremp Basin has reached a very high level, with all that this implies for human health. Attending to the requirements of a sustainable development, which is the only way of granting a future for the mountainous regions, this paper hints at some solutions to lessen the serious problems generated by the intensification ofpig cattle raising.
