“…Since restoration has changed the landscape, we try to assess soil characteristics, composition of vegetation and cover and, therefore, their influence on erosion processes, runoff and suspended sediment concentration. This paper is important because the Saldaña Badlands are located in a sub‐humid continental Mediterranean climate, whereas most studies have been completed in wetter (Gallart et al ., ; Vallauri et al ., ; Nadal‐Romero et al ., ; Martínez‐Casasnovas et al ., ; Clarke and Rendell, ); warmer (Boix‐Fayos et al ., ); and/or drier (Finlayson et al ., ; Cerdá, ; Cantón et al ., ; Castillo et al ., ; Faulkner et al ., ; Desir and Marín, ; Laudicina et al ., ) environments.…”

“…They have also observed that the lowest zone of the badlands varied from 0.36 mm yr ‐1 deposition to 0.06 mm yr ‐1 surface lowering. In Spain, Desir and Marín () measured high erosion rates in non‐vegetated badlands of the Bárdenas Reales, ranging from 32 to 77 Mg ha ‐1 yr ‐1 . In contrast, Cantón et al .…”

“…The survey yielded an average siltation ratio of 7.6 t ha ‐1 yr ‐1 . This value, which includes a period when badlands turned from bare to partially covered, corresponds to 16% of the average sediment yield for both bare (Desir and Marín, ) and partially covered (Martínez‐Casasnovas et al ., ) badlands in Spain.…”

“…This hypothesis is appropriate because while it rains less in Saldaña, the topography and vegetation cover are similar. In contrast, the average gully erosion rate in bare badlands similar to the Saldaña bare slopes ranges from 5 to 30 mm yr ‐1 (Clarke and Rendell, ), and Desir and Marín () have also measured erosion rates up to 77 Mg ha ‐1 yr ‐1 in the Bárdenas Reales badlands.

This paper presents the history of badland generated in the Saldaña region, Spain; as well as the main responses eight decades after the start of restorationin terms of vegetation, soil and erosive processes. The restoration consisted of intense reforestation and construction of more than 100 check dams and numerous wattle fences. Presently, the dense vegetation (87% cover) contrasts markedly with the degraded landscape from the early 20th century (5% cover). The thickness of litter and the natural presence of some species (Quercus pyrenaica, Paeonia broteroi and Lactarius deliciosus) clearly indicate the recovery of the site. The development of the forest cover shows that the intervention has the potential to recover almost 90% of the area. There is also evidence of soil regeneration, although some properties (erodibility, resistance to penetration and shear-strength resistance) are not that different between the forested and degraded areas. In the restored zones, runoff is negligible, since a thick layer of moss covers the spillways of all the check dams. Erosion has almost been stopped by the effects of vegetation cover, litter and higher infiltration rates (infiltration rate in forested slopes is 43.4 times greater than in bare slopes). Sediment detachment, such as landslides, mudflows and piping, still occur, but are restricted to the degraded zones. Furthermore, even when sediments are mobilized from the upper degraded hillslopes during the larger storms events (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010), check dams and the lower elevation restored forest-buffers effectively work to reduce the sediment yield into the Carrión River by almost three orders of magnitude (<10 2 mg L -1 ), compared with data from the 1930s and 1940s (>10 5 mg L -1 ). Ayerbe (1930) wrote that the land was almost bare; b Azcarretazábal (1963) made one list with the species from the badlands; c from the Martínez de Azagra et al. (1997) inventory and our fieldwork; d because it was not fully grown at the time of our observations. 1568J. NAVARRO HEVIA ET AL.

“…Para predecir la degradación de los suelos por erosión hídrica se han utilizado ampliamente diferentes métodos que permiten identificar pérdidas actuales y 3 potenciales no tolerables, sobre la base de las cuales se seleccionan las mejores prácticas de control de la erosión (Desir y Marín, 2009;Oñate 2004). Los aspectos anteriores justifican el desarrollo de una investigación donde el principal objetivo es estimar la agresividad climática en el sector hidrogeológico CA-II-I del municipio de Venezuela en la provincia Ciego de Ávila, Cuba a través del Índice Modificado de Fournier y el ajuste a la función de distribución de Gumbel asociados a los períodos de retornos que contribuya a la evaluación del comportamiento futuro de este fenómeno y permita trazar estrategias para la conservación del suelo en las áreas agrícolas donde se desarrolla la investigación.…”

Se desarrolla una investigación con el objetivo de determinar la existencia de Agresividad Climática y el comportamiento futuro de este fenómeno a través del Índice Modificado de Fournier y el ajuste a la función de Distribución de Gumbel asociados a los Períodos de Retornos, en la misma se demostró la existencia del fenómeno en todas las áreas agrícolas que tributan a los equipos pluviométricos del sector analizado, con un elevado por ciento de impactos moderados, altos y muy alto, se obtuvieron además modelos matemáticos predictivos con una gran confiabilidad; así como, curvas para los períodos de retornos de 5, 10, 15, 20, 30 y 50. Lo anterior permitirá trazar estrategias de mitigación y adaptación para la conservación del suelo y la vegetación, sobre todo por ser un sector eminentemente agrícola, afectados también por erosión eólica y antropogénica.
