“…15b). To the contrary, Muñoz-Díaz and Rodrigo (2004) found that the negative phase of ENSO, La Niña, leads to a low probability of drought in spring but for the whole northern IP, while Lorenzo et al (2010) also concluded that La Niña almost always announces dry springs in the NWIP. Unlike these authors in this study, we use an index that contemplates ocean and atmospheric conditions to identify the phases of ENSO, and another index that contemplates both precipitation and evapotranspiration to identify drought conditions.…”

“…The NWIP is a homogeneous region in terms of the total precipitation variance over the IP (Rodríguez-Puebla et al, 1998;Muñoz-Díaz and Rodrigo, 2004) and consequently, also in terms of the influence of droughts (Russo et al, 2015). Figure 3 illustrates the temporal evolution of moderate, severely, and extremely dry conditions (according to the classification shown in Table 1) through the SPEI at a temporal scale of 1 to 24 months.…”

“…Therefore, multiple analyses have been used to investigate droughts and their impact on the availability of water resources in the IP. These include the implementation of circulation weather type (CWT) classifications (Cortesi et al, 2014;Ramos et al, 2014); identification of atmospheric blocking events (Sousa et al, 2016); and assessments of climatic teleconnection patterns like the North Atlantic Oscillation (NAO; Muñoz- Díaz and Rodrigo, 2004;Trigo et al, 2004;deCastro et al, 2006a), which is considered to be a dominant mode of climate variability for Europe (Visbeck et al, 2001); the Arctic Oscillation (AO;deCastro et al, 2006a); the El Niño-Southern Oscillation (ENSO) (Vicente- Serrano, 2005); and the Scandinavian pattern (SCAND;deCastro et al, 2006a). The impacts of drought in the IP have been widely investigated.…”

Abstract. Drought is one of the world's primary natural hazards because of its environmental, economic, and social impacts. Therefore, monitoring and prediction for small regions, countries, or whole continents are challenging. In this work, the meteorological droughts affecting the Miño–Limia–Sil hydrographic demarcation in the northwestern Iberian Peninsula during the period of 1980–2017 were identified. For this purpose and to assess the combined effects of temperature and precipitation on drought conditions, the 1-month standardized precipitation evapotranspiration index (SPEI1) was utilized. Some of the most severe episodes occurred during June 2016–January 2017, September 2011–March 2012, and December 2014–August 2015. An empirical-orthogonal-function analysis revealed that the spatial variability of the SPEI1 shows strong homogeneity in the region, and the drought phenomenon consequently behaves in the same way. Particular emphasis was given to investigating atmospheric circulation as a driver of different drought conditions. To this aim, a daily weather type classification based on the Lamb weather type (LWT) classification was utilized for the entire Iberian Peninsula. Results showed that atmospheric circulation from the southwest, west, and northwest are directly related to wet conditions in the Miño–Limia–Sil hydrographic demarcation during the entire hydrological year. Contrastingly, weather types imposing atmospheric circulation from the northeast, east, and southeast are best associated with dry conditions. Anomalies of the integrated vertical flow of humidity and their divergence for the onset, peak, and termination of the 10 most severe drought episodes also confirmed these results. In this sense, the major atmospheric teleconnection patterns related to dry and wet conditions were the Arctic Oscillation, Scandinavian pattern, and North Atlantic Oscillation. Hydrological drought investigated through the standardized runoff index was closely related to dry and wet conditions revealed by the SPEI at shorter temporal scales (1–2 months), especially during the rainy months (December–April).

“…Lugares de Importancia Comunitaria (LIC) y 644 Zonas de Especial Protección para las Aves (ZEPA), los parques nacionales 14, los parques naturales (135) y las reservas de la biosfera (48). La literatura científica sobre el papel de las medidas de protección es abundante, pero se puede diferenciar, grosso modo, entre los expertos que destacan los resultados positivos de su aplicación: mejora socioeconómica de la población rural (Ervin et al, 2010;Martínez y Romero, 2003), incidencia en las políticas de desarrollo rural a través de la iniciativa Liaisons entre activités de Developement de L'Economie Rural (LEADER) (Jeong et al, 2016); y quienes destacan los negativos que se centran en cuestiones como la carencia de uniformidad legislativa para proteger espacios similares (Hoyos et al, 2012;Mulero, 2004), su incidencia en la despoblación y degradación natural (Mora et al, 2015;Romero et al, 1999) y, sobre todo, la escasa aceptación o, directamente, rechazo por parte de la población local (Troitiño, 1994), así como su papel en la conservación (Louette et al, 2011).…”

Ruta de La Reserva de la Biosfera de La Rioja: ejemplo de integración entre ser humano y medio

Biosfera (MaB) de la UNESCO. Es un ejemplo de lo que representan estos espacios desde el punto de vista social, económico y científico para la conservación del medio dentro del marco del desarrollo sostenible. Incluye a 40 municipios marcados por el declive demográfico, la falta de servicios y de accesibilidad, pero también afortunados por el patrimonio natural y cultural que atesoran. El aprovechamiento como recurso de las formaciones geológicas y el relieve, la biodiversidad, las icnitas, las aguas termales, la fisonomía de los pueblos y las manifestaciones culturales en la Reserva convive con la actividad humana en un equilibrio armonioso que exige un esfuerzo continuado. La lucha por su supervivencia es el reto más importante al que se enfrentan sus habitantes, como actores del territorio, y el conjunto de la sociedad como responsables de su conservación para el disfrute de las generaciones futuras.
