Transformaciones en el paisaje del Pirineo como consecuencia del abandono de las actividades económicas tradicionales

Runoff and sediment yield from land under various uses in a Mediterranean mountain area: long‐term results from an experimental station

“…On the most marginal slopes, shifting agriculture prevailed, with two or three years of cultivation alternating with 25-30 years of fallow (Lasanta et al, 2006). During the 1950s and 1960s most of the cultivated fields on the hillslopes were abandoned, initiating a complex process of plant recolonization that resulted in a generalized expansion of shrubs and forests (Vicente-Serrano et al, 2000). The fields in the bottom of the valley are still cultivated, although cereal crops have been replaced by grazing and cutting meadows.…”

El turismo de nieve como estrategia de desarrollo en el Pirineo aragonés

“…Además, el monocultivo turístico conduciría a la degradación del paisaje (un activo destacado de la economía pirenaica), creado y moldeado por el hombre durante siglos de utilización agropecuaria (Galop, 1998). La disminución drástica de la ganadería extensiva conduce a la subutilización de pastos naturales y al abandono de prados, lo que permite el avance de matorrales y bosques de sucesión y conduce a la disminución de la diversidad paisajísti-ca (Vicente-Serrano et al, 2000), con consecuencias en el incremento del riesgo de incen-dios, en la conservación del suelo, en la disponibilidad de agua en las cuencas y en el atractivo turístico (Buckley et al, 2000;Lasanta et al, 2005;García-Ruiz et al, 2008).…”

Among rewilding mountains: grassland conservation and abandoned settlements in the Northern Apennines

“…'Implicit in the wilderness idea is an anti-human bias that seeks to present nature as the antithesis of culture' (Gade, 1999, p. 6) Background In many Southern European mountain regions, the complementary processes of urbanisation and deagrarianisation have led to changes in rural land use practices, often leading to the complete abandonment of agricultural land since the 1950s (on European mountains in general see MacDonald et al, 2000; on Mediterranean mountains in particular see Papanastasis, 2012). In a case study in the Borau Valley of the Spanish Pyrenees, an area characterised by severe depopulation during the 20 th century, Vicente-Serrano, Lasanta, and Cuadrat (2000) noticed increased woody vegetation on former agricultural land and called this process the 'banalization of landscape'. Agricultural abandonment was also observed in the second half of the past century in Italian mountain regions (Vecchio, 1989).…”
