“…Specifically, in the Mediterranean mountains of Spain, the vegetation trends during the past few decades have been related to the abandonment of traditional activities [43,51,94,95]. Vidal-Macua et al [95] discuss how land use management and the disturbances that are caused by the activities in the different land covers have been and continue to be the main driving force in vegetation succession.…”

Monitoring NDVI Inter-Annual Behavior in Mountain Areas of Mainland Spain (2001–2016)

2018

Currently, there exists growing evidence that warming is amplified with elevation resulting in rapid changes in temperature, humidity and water in mountainous areas. The latter might result in considerable damage to forest and agricultural land cover, affecting all the ecosystem services and the socio-economic development that these mountain areas provide. The Mediterranean mountains, moreover, which host a high diversity of natural species, are more vulnerable to global change than other European ecosystems. The protected areas of the mountain ranges of peninsular Spain could help preserve natural resources and landscapes, as well as promote scientific research and the sustainable development of local populations. The temporal statistical trends (2001–2016) of the MODIS13Q1 Normalized Difference Vegetation Index (NDVI) interannual dynamics are analyzed to explore whether the NDVI trends are found uniformly within the mountain ranges of mainland Spain (altitude > 1000 m), as well as in the protected or non-protected mountain areas. Second, to determine if there exists a statistical association between finding an NDVI trend and the specific mountain ranges, protected or unprotected areas are studied. Third, a possible association between cover types in pure pixels using CORINE (Co-ordination of Information on the Environment) land cover cartography is studied and land cover changes between 2000 and 2006 and between 2006 and 2012 are calculated for each mountainous area. Higher areas are observed to have more positive NDVI trends than negative in mountain areas located in mainland Spain during the 2001–2016 period. The growing of vegetation, therefore, was greater than its decrease in the study area. Moreover, differences in the size of the area between growth and depletion of vegetation patterns along the different mountains are found. Notably, more negatives than expected are found, and fewer positives are found than anticipated in the mountains, such as the Cordillera Cantábrica (C.Cant.) or Montes de Murcia y Alicante (M.M.A). Quite the reverse happened in Pirineos (Pir.) and Montes de Cádiz y Málaga (M.C.M.), among others. The statistical association between the trends found and the land cover types is also observed. The differences observed can be explained since the mountain ranges in this study are defined by climate, land cover, human usage and, to a small degree, by land cover changes, but further detailed research is needed to get in-depth detailed conclusions. Conversely, it is found that, in protected mountain areas, a lower NDVI pixels trend than expected (>20%) occurs, whereas it is less than anticipated in unprotected mountain areas. This could be caused by management and the land cover type.

“…Por los que respecta a los indicadores demográficos, que nos hablan de una cierta desaceleración del crecimiento, no pueden ser directamente puestos en relación con las dinámicas evolutivas del paisaje. En otras áreas protegidas de montaña el abandono agrario ha estado acompañado de una importante pérdida de población (Lasanta-Martínez et al, 2005;Jiménez Olivencia et al, 2015), sin embargo, este proceso no es visible en este caso, ya que la población ha podido ser fijada por la influencia de la ciudad y la fortaleza del sector turístico (Mcdonald et al, 2009;Abrantes et al, 2016).…”

“…Por otra parte la decadencia de los sistemas tradicionales de explotación resulta una amenaza para el sostenimiento de paisajes culturales valiosos, que sólo pueden asegurar su supervivencia con la permanencia de las actividades agro-ganaderas y forestales. Son numerosos los estudios que demuestran que el abandono de las tierras y el cambio de modelo socioeconómico están estrechamente relacionados con las dinámicas de cambio que se observan en el paisaje (González-Puente et al, 2014;Mallinis et al, 2014;Jiménez et al, 2015;Otero et al, 2015). En muchos casos, como el que ahora nos ocupa, estos cambios socioeconómicos se agudizan por el efecto que los grandes espacios urbanos próximos a su perímetro ejercen sobre la economía local.…”

Evolución Reciente de las Áreas Protegidas en Portugal: El Caso del Parque Natural da Arrábida

La situación de proximidad de muchos espacios naturales protegidos respecto a áreas urbanas dinámicas puede desencadenar intensos procesos de cambio que pongan en riesgo el mantenimiento de los valores naturales y patrimoniales propios de estos espacios. El Parque Natural da Arrábida está situado en el Área Metropolitana de Lisboa y se encuentra a sólo 40 kilómetros de la capital de Portugal. El presente artículo analiza los cambios en los usos y coberturas del suelo en el periodo más reciente para identificar los principales procesos de transformación del paisaje en este espacio protegido. Además se lleva a cabo un análisis, a partir de indicadores demográficos y económicos, de su área de influencia (los municipios de Setúbal, Sesimbra y Palmela). Estos indicadores sirven al propósito de vincular la evolución del paisaje del área protegida con la del modelo socioeconómico de su entorno más próximo.

“…In this work, we analyze the colonization pattern of abandoned croplands by Quercus pyrenaica in the Sierra Nevada mountain region. This mountain has undergone significant land-use changes in the last 50 years [45] with increases in forest densities [19], and tree growth [46]. We are interested in exploring the colonization pattern of abandoned croplands by Q. pyrenaica on both slopes of Sierra Nevada.…”

Land abandonment is a major global change driver in the Mediterranean region, where anthropic activity has played an important role in shaping landscape configuration. Understanding the woodland expansion towards abandoned croplands is critical to develop effective management strategies. In this study, we analyze the colonization pattern of abandoned croplands by Quercus pyrenaica in the Sierra Nevada mountain range (southern Spain). We aimed to assess differences among populations within the rear edge of the Q. pyrenaica distribution. For this purpose, we characterized (i) the colonization pattern of Q. pyrenaica, (ii) the structure of the seed source (surrounding forests), and (iii) the abundance of the main seed disperser (Eurasian jay, Garrulus glandarius). The study was conducted in five abandoned croplands located in two representative populations of Q. pyrenaica located on contrasting slopes. Vegetation plots within three habitat types (mature forest, edge-forest and abandoned cropland) were established to compute the abundance of oak juveniles. The abundance of European jay was determined using data of bird censuses (covering 7 years). Our results indicate that a natural recolonization of abandoned croplands by Q. pyrenaica is occurring in the rear edge of the distribution of this oak species. Oak juvenile abundance varied between study sites. Neither the surrounding-forest structure nor the abundance of jays varied significantly between study sites. The differences in the recolonization patterns seem to be related to differences in the previous- and post-abandonment management.
