High-intensity rainfall can raise fluvial channel levels, increasing the risk of flooding. Maximum precipitation depths are used to estimate return periods and, thus, calculate the risk of this type of event. To improve these estimates in Southwest Europe, we studied the behavior of extreme rainfall using the historical records of San Fernando (Cád...

This study estimates the pluviometric evolution between the 13th and 19th centuries on the southwestern Iberian Peninsula based on the historic records of the impacts of the Guadalquivir River flooding on the city of Seville (Spain). The main documentary source was “Critical history of the floods of the Guadalquivir in Seville”, published in 1878,...

One of the characteristics of the Mediterranean climate is the irregularity of its intra-annual precipitation. Thus, very intense and short rain events can have a serious impact due to the sudden increase of the water level in drainage basins, with the subsequent risk of pluvial and riverine floods. This study analyses the evolution––and the return...

The effect of climate change on autochthonous malaria, in countries where it is still endemic, and the risk of re-emergence in those where it had already been eradicated, is a widely discussed topic nowadays. The role that the increase in temperatures can play is especially relevant in the biological cycle of both the vector and the parasite that c...

Since the early twentieth century, the intensity of malaria transmission has decreased sharply worldwide, although it is still an infectious disease with a yearly estimate of 228 million cases. The aim of this study was to expand our knowledge on the main drivers of malaria in Spain. In the case of autochthonous malaria, these drivers were linked t...

Malaria is one of the most cited vector-borne infectious diseases by climate change expert panels. Malaria vectors often need water sheets or wetlands to complete the disease life cycle. The current context of population mobility and global change requires detailed monitoring and surveillance of malaria in all countries. This study analysed the spa...

The annual Emberger’s pluviothermic Q index is suitable for classifying the Mediterranean climate and drawing conclusions about the spatiotemporal behaviour from which environmental effects may derive. The Q index was calculated to analyse its temporal variability throughout the study period of 1901–2012 in the Southwest of the Iberian Peninsula. T...

Malaria is one of the infectious diseases with the highest number of cases worldwide. It has always been linked to aquatic environments, since these can be a necessary reservoir for the anophelines that transmit the disease. This study analyses the role that unhealthy water bodies have played, since the early 20th century, in the most endemic and/o...

Un aspecto destacable en el conocimiento del clima es la determinación del régimen pluviométrico intraanual. Además, es un elemento importante para la gestión ambiental. La caracterización de la distribución intranual, con su variabilidad interanual, requiere el análisis conjunto de dos factores: el volumen de los episodios de lluvia y su correspon...

Understanding the intra-annual distribution of rainfall is an important element for climatic classification and serves as a basis for natural resources management. The present study analyses multi-annual irregularities of the rainfall distribution throughout the year in the period 1941–2010, in the hydrographic basins of the Iberian Peninsula. In o...

The temporal irregularity of rainfall, characteristic of a Mediterranean climate, corresponds to the irregularity of the environmental effects on soil. We used aggressiveness as an indicator to quantify the potential environmental impact of rainfall. However, quantifying rainfall aggressiveness is conditioned by the lack of sub-hourly frequency rec...

Rainfall aggressiveness causes environmental impacts and it is related to several natural hazards. Therefore, this parameter has been chosen as an environmental indicator. The present study is based on the monthly estimated rainfall using the Precipitation Runoff Integrated Model (SIMPA) for each Spanish hydrographic basin from 1940 to 2010. The ma...

Unlike other aquatic continental ecosystems such as lakes, small coastal brooks have not been used as indicators of anthropogenic or climatic impacts. Our study addresses reconstructing the evolution of coastal brooks in the southwest of Spain from the early 17th century to the end of the 20th century using fieldwork, remote sensing, historical sou...

Nuestro objetivo, en este apartado, es integrar los cambios que han tenido lugar en las lagunas del antiguo Coto de Doñana con los factores principales que han causado dichos cambios durante los últimos 400 años. La comprensión de las alteraciones históricas de los hábitats naturales puede ayudar a los gestores a diseñar la manera de revertir décad...

Las variaciones y fluctuaciones climáticas juegan un papel clave en la alimentación y temporalidad de las lagunas. Estos cambios tienen mayor peso cuánto más sostenidos son en el tiempo. Por ello, las tendencias climáticas seculares deben ser consideradas como un elemento fundamental para entender no solo los cambios en las lagunas de Doñana, sino...

The possible connectivity between the spatial distribution of water bodies suitable for vectors of malaria and endemic malaria foci in Southern Europe is still not well known. Spain was one of the last countries in Western Europe to be declared free of malaria by the World Health Organization (WHO) in 1964. This study combines, by means of a spatia...

The annual rainfall irregularity has its correspondence in the irregularity of the environmental effects it generates. The rainfall aggressiveness is a factor with high environmental impact. It is associated, in turn, other effects (torrential, runoff, erosivity, silting...). Analysis of aggressiveness of rain, supports a dual approach based on the...

This paper analyses a reconstruction of changes from the 17th to the 20th centuries in peat bogs with Erica ciliaris Loefl. ex L. heathlands in southwestern Europe.

Variability in precipitation affects annual total records and causes instability in rainfall distribution throughout the year. Our aim in this study was to develop a procedure, based on pluviometric centralisation and dispersion parameters, that is able to characterise rainfall distribution throughout a year of precipitation in a unique, condensed...

Cladosporium spores are ubiquitous in the air and are included in the fungal contaminants that define environmental quality. This paper provides an updated review of their concentration in the Iberian Peninsula, based on data from 12 sampling stations collected using a common non-viable volumetric sampling method and the same subsequent data-treatm...

This paper provides an updated of airborne Alternaria spore spatial and temporal distribution patterns in the Iberian Peninsula, using a common non-viable volumetric sampling method. The highest mean annual spore counts were recorded in Sevilla (39,418 spores), Mérida (33,744) and Málaga (12,947), while other sampling stations never exceeded 5,000....

RESUMEN Habitualmente los impactos antropogénicos son mucho más conspicuos que los climáticos. Por ello pueden contribuir a que los efectos del cambio climático pasen desapercibidos. Este estudio plantea la posibilidad de detectar si ambos tipos de impactos han afectado de forma sinérgica a los humedales del suroeste de España. Para ello hemos cuan...

Soil erosion is remarkable environmental effect caused by precipitation. From different fields has been studied erosion, but are rare studies related to variation in time. This study is based on monthly precipitation estimated by the SIMPA (Mtº of Environment) for each Spanish basin during 1940-2010. The basins have been grouped into six areas anal...

Recent studies have shown the value of place names as environmental indicators. Until now they have not been applied to the effects of climate change, because verifying such relationship by this approach requires a multidisciplinary analysis and a study area where the anthropic impact has been recent. This study aims to test the possibility in a st...

Unlike rivers, creeks have not been used as proxy data or as indicators of climatic changes. This paper approaches this possibility by means of a reconstruction of the evolution of the littoral creeks in SW Spain between the XVIIth century and the late XXth century. During these four centuries, these creeks lost 84.7% (54.3 km) of their length esti...

One noteworthy aspect of climate knowledge is the identification of rainfall patterns intraanual. A multitude of environmental and social processes are closely linked with the behavior throughout the year present rainfall. In the Iberian Peninsula intraanual regime is an indicator for climate classification, in which the common Mediterranean domain...

During the last few decades, studies have been performed and evidence has been found concerning the importance of the climatic period known as the “Little Ice Age” (mid 15th century through late 19th century). However, most of the studies have been focused to more northern latitudes and, therefore, scarce studies have still been made on the Mediter...

Basidiomycetes produce large quantities of spores that are dispersed by the wind over long distances. Some species can release billions of spores in a day, many of which are important aeroallergens associated with asthma and allergic rhinitis. The results of a survey carried out in the city of Seville during two consecutive years, using a Hirst-typ...

At least until the mid of the 20th century, the eastern coast of the province of Huelva (South-West of Spain) was a malaria endemic area. The possibility that this disease, that disapperared in temperate areas along the second half of the 20th century, rises due to the global warming, have been raised by some authors. In this work data of this path...

The Basidiomycetes produce a large amount of spores that are wind dispersed to long distances, many of those spores are important aeroallergens that are involved in asthma and allergic rhinitis. The concentration of these basidiospores in the air is influenced by the meteorological factors. In a survey carried out in Seville during two consecutive...

The aeromycological behaviour in a certain place is conditioned by its climate, in such a way that if we know the existing relation among the different climatic variables and the spores concentration in the air, we will be able to elaborate predictive models that would allow us to calculate their concentration at a certain moment. In this work we h...

Between the Las Madres and Palos lagoons Natural Area and the western area of Doñana Natural Park (Huelva, SW Spain) there is a group of disminished and almost silted creeks. At least since the 19th century, these creeks, along with their associated riparian woods, have experienced a great regression. Four centuries ago there were at least thirteen...

We analyzed the evolution of the series of temperatures as a result of the transfer of the observatory of Badajoz from the urban center to the outside. This system allows to obtain an indicator of the effect of the heat island in the cities. The results indicate that such effect is approximately stable throughout the year and must to the nocturnal...

Doñana, constituye en el ámbito andaluz, español y europeo, un auténtico referente en cuanto a la conservación y a la política de Espacios Naturales Protegidos. Dentro de este marco, sin duda, uno de los aspectos más sobresalientes es el extenso y variado abanico de humedales (Sousa, 2004). Sin embargo ¿hasta qué punto los humedales continentales d...

Jusqu'au milieu du XXe siècle, tout au moins, le littoral oriental de la région de Huelva (sud-ouest de l'Espagne) constituait une zone endémique de paludisme. Certains auteurs pensent qu'il est possible que cette maladie, disparue des zones tempérées pendant la seconde moitié du XXe siècle, ne réapparaisse du fait du Réchauffement Global de l'atmo...
