Propuestas de gestión para reducir la erosión costera y la restauración de hábitas dunares
Durante los últimos 50 años se han producido cambios significativos en las cubiertas y usos del suelo, principalmente aquellos catalogados como artificiales. Este proceso, y su generalización a escala global, afectan de forma directa a las funciones básicas del suelo, acrecentando otros problemas como pueden ser la pérdida de biodiversidad, contami...
El sellado antropogénico constituye uno de los principales procesos de degradación física de los suelos y tiene como principal resultado su impermeabilización, con efectos negativos muy importantes. Los estudios sobre este tema son relativamente recientes, apareciendo las primeras investigaciones relevantes a finales del siglo XX. Sin embargo, no s...
Anthropogenic soil sealing is one of the most important types of soil degradation. It results in the loss of fertile soils, reduced water infiltration capacity, diminished recharging of aquifers and, when high-intensity rainfall occurs, increased runoff and flooding. In order to reduce the negative impacts on human activities and natural ecosystems...
The risk of flooding on the Spanish Mediterranean coast is a constant threat whose importance has progressively increased in recent decades despite the enormous efforts made to mitigate it. Of the two strategies practiced to reduce the effects of this danger, structural measures have prevailed to a great degree over non-structural ones during this...
Sustainable grazing land management (SGLM) is crucial to prevent land degradation and support food security and human well-being and may contribute to climate change mitigation and adaptation. To facilitate a wide-scale adoption of SGLM, further quantification of its multiple impacts and tradeoffs between ecosystem services is needed. The objective...
In September 2019 a DANA affected the Southeast of Spain with a special impact on the Segura Basin and the Region of Murcia. Heavy rainfall caused widespread flooding, very serious damage and generally affected the whole population. The main objective of this work was to analyse this episode through a follow-up of all the news published in two regi...
Abandoned lands occupy extensive territories in some Spanish regions, particularly in mountain areas and semiarid environments. These lands originate very diverse landscapes depending on the climatic conditions, the age of abandonment, the management before and after abandonment, and the disturbances that they suffer during the post-abandoned proce...
Rainfall is the key factor to understand soil erosion processes, mechanisms, and rates. Most research was conducted to determine rainfall characteristics and their relationship with soil erosion (erosivity) but there is little information about how atmospheric patterns control soil losses, and this is important to enable sustainable environmental p...

Soil erosion by water in abandoned dry terraces is one of the most important environmental problems in semi-arid areas, enhancing biological degradation and reducing possible resources that can be obtained. However, little is known about the effects of the types of lithology and soil properties on the early stages of soil erosion. Therefore, the ma...
In recent decades, the region studied has experienced a significant urban expansion driven
by the residential tourism. This resulted in a considerable environmental impact. To study this process and its impacts, we have analyzed the types of housing and population,
urban surfaces digitized in three dates (1956, 1981 and 2011) and estimated the leng...

Un grupo de investigadores (geógrafos, biológos, ambientólogos, agrónomos y técnicos de la...
Resumen: Se evalúan y analizan las transformaciones de carácter urbanístico producidas en la Comarca del Campo de Cartagena Mar Menor (Sureste de España) como consecuencia de la expansión edificatoria y lo que ello repercute en forma de sellado artificial del suelo y aumento del riesgo de inundación. Los resultados han puesto de manifiesto cómo el...
The rural environment accounts for more than half of the Spanish landscape and is formed mainly of agricultural land and forests, which support varied uses and economic activities. However, the abandonment of agricultural activities and rural areas, or agricultural modernisation and intensification, produces important population and territorial cha...
We evaluate and analyse urbanistic transformations that have occurred in Campo de Cartagena-Mar Menor (southeast Spain) as a consequence of the expansion of new building and how flooding has increased in the area as result of artificial sealing of the soil. The results showed that the higher risk of flooding is closely related to the increase in so...
The culture by greenhouses has been one of the greatest agricultural transformations in the world, but especially in the southeastern Spanish. The main objective of this study was to analyze the transformation of the landscape and some of its environmental effects that, in the region of Cartagena-Mar Menor, have taken place in the recent decades as...
Slips are little known mud-coated structures several centimeters thick, produced by gravity-driven flows on free vertical surfaces. We have differentiated a sequence formed by three main morphologies: mud drips, slips and pseudo-stalactites. This study, located in the badlands of the Guadix and Baza basins (SE Spain), suggests that formation of mud...

En el Sureste peninsular son constantes las situaciones de inestabilidad convectiva alimentadas en niveles altos atmosféricos por irrupciones de masas de aire ártica/polar. Bajo estas condiciones, debido al desplazamiento de los núcleos convectivos, las cuencas y valles fluviales intrabéticos son bastante proclives a los meteoros severos, tales com...
Las inundaciones han sido y son un riesgo climático, con efectos catastróficos, siempre presente en la Región de Murcia. Las esporádicas, pero recurrentes, lluvias torrenciales han sorprendido en cualquier época histórica a sus habitantes, provocando graves daños a infraestructuras, viviendas y campos de cultivo, así como gran número de pérdidas de...
The intensification of agricultural activity in the area of Marina de Cope (Murcia), since the eighties of the last century, manifested in the transition from a traditional rain-fed agriculture to a modern market, intensive agriculture, resulted in the occupation of spaces traditionally unproductive as the foothills and the numerous sides to this c...
In recent years the investigation of soil erosion in semiarid environments has concentrated on the controls on runoff and sediment production on hillslopes. A key facter in these controls is vegetation. In this research proyect we seek to establish the relationships between vegetation cover and erosional processes through the effects of interceptio...
Erosive processes of soil by water have always showed serious problems, mainly in those areas such as the Mediterranean environment, where the vigour of the surface, frequently low resistence of materials, little vegetation cover or bare ground, hard rainfalls and deficient management of resources, have led to favourable conditions for soil degrada...
