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...

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...

In sozialkonstruktivistischen Ansätzen der Landschaftsforschung wird „Landschaft“ nicht als „objektiv“ gegeben gefasst: Das Wissen darüber, was „Landschaft“ sei und welchen Deutungen und (Be)Wertungen sie unterliegt, ist aus dieser Perspektive das Ergebnis „sedimentierter Erfahrungen“, die sich weniger in unmittelbarer Konfrontationmit den physisch...

In approaches of social constructivist landscape research, “landscape” is not addressed in an objective way. From this perspective, the knowledge of landscape itself, its meaning, evaluation and assessment are the result of “sedimented experiences”. These experiences are hardly based on the direct confrontation with physical elements, they are rath...

Thermal dynamics of lakes has a key role in chemical and biological processes in lakes including nutrient distributions and phytoplankton growth. Applications of hydrodynamic models to lakes can provide insights into possible future alterations in thermal dynamics induced by climate change. In this study, we present the calibration and validation o...

Lakes are sensitive to changes in climate and human activities. Over the last few decades, Mediterranean lakes have experienced various problems due to the current climate change (drought, flood, warming, salt accumulation, water quality changes, etc.), often amplified by water use, intensification of land use activities, and pollution. The overall...

Resumo The calibrated of bid rents of spatial interaction models can be very useful spatial economic indicators. The paper shows that the bid rents of the spatial interaction model calibrated for the Munich Region are strongly related to the prices of land. Being so, it is possible to evaluate the impacts of changes in exogenous variables such as t...

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...

Por ello, las tendencias seculares y los escenarios climáticos parecen perfilar un escenario climático futuro para Doñana con una mayor evapotranspiración y, lo que es más importante, con una menor disponibilidad hídrica a escala secular. Estos resultados están en consonancia con estudios recientes para toda España (Argüeso y col., 2012). Estos aut...

The fast growing popularity of digital media thoroughly changes the way we perceive our environment and the means by which we orientate ourselves. But even though the benefits of digital media are manifold, the problems arising with these changes cannot be ignored. With regards to spatial orientation this means challenges for spatial capabilities a...

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...

Regional climate models (RCM) provide sitespecific meteorological data at a suitable spatial resolution for the estimation of future climate-driven changes in aquatic ecosystems. In this study, we used meteorological data from the RCM weather-situation-based regionalization method (WETTREG), available for Germany, to force a one-dimensional hydrody...

In this study we implemented groundwater inflow to the one-dimensional hydrodynamic simulation of lake water temperatures to improve the reproduction of the real water temperatures by the simulation results for Lake Ammersee, Southern Germany. As the hydro-geological conditions at Lake Ammersee have not yet been finally clarified, we created simula...

We report on the calibration of the one-dimensional hydrodynamic lake model Dynamic Reservoir Simulation Model to simulate the water temperature conditions of the pre-alpine Lake Ammersee (southeast Germany) that is a representative of deep and large lakes in this region. Special focus is given to the calibration in order to reproduce the correct t...

Climate change-derived higher air temperatures and the resulting increase in lake surface temperatures are known to influence the physical, biological and chemical processes of water bodies. By using hydrodynamic lake models coupled with regional climate models the potential future impact of a changing climate can be investigated. The present study...

Due to climate change, an increase in the surface temperature of water bodies is located. As a result, physical and biogeochemical processes in lakes will be influenced. By the use of hydrodynamic models, which are combined with regional climate models, it is possible to predict limnological impacts of the climate change. The objective of the prese...

In order to enhance our research work on the impact of climate change on bodies of water, it is necessary to establish coupled hydrodynamic and ecosystem models that take into account simulated data of climate models. We assume that the coupled hydrodynamic models, along with the regional climate models, can serve to gain further knowledge on the f...

Throughout the last decades of the 20th century, nutrient concentrations in some continental aquatic ecosystems increased due to human activities in their catchment areas. This is also possible to observe in the Lake Ammersee, situated in South-East of Germany, 30 km away from the City of Munich. The lake and its catchment area are representative o...

In the past decades, nutrient concentrations in several pre-Alpine lakes in central Europe have increased due to human activity in the catchment area. Here, we examine whether this trend will continue in the future, through our analysis of the development of the trophic status, over a period of 25 years (1984–2009), of the pre-Alpine, dimictic temp...

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...
