“…Sin embargo, es importante aclarar que en este caso se adoptó una escala de análisis microlocal que permitiera la incorporación de los distintos barrios como unidades de análisis. Es necesario tener en cuenta que la evaluación del fenómeno de sellado del suelo es escala-dependiente, por lo que esta ejercerá influencia sobre los resultados obtenidos (García-Alvarado et al, 2014). De esta manera, queda planteada la continuidad del trabajo hacia un análisis interescalar que permita la incorporación de otros elementos del espacio urbano y la identificación de patrones de ocupación de las áreas periurbanas.…”

El objetivo del trabajo es analizar el proceso de sellado del suelo a escala microlocal, tomando como caso de estudio el periurbano de Bahía Blanca, Argentina. A través de la interpretación visual de imágenes satelitales y considerando a los barrios residenciales como unidades de análisis se obtuvieron indicadores del sellado del suelo. Estos se correlacionaron con variables representativas de la vegetación, densidad de ocupación e indicadores urbanísticos a través de pruebas de Spearman no paramétricas. Las correlaciones significativas se dieron con la densidad urbana de viviendas, con el porcentaje de lotes vacantes y con el de vegetación leñosa presente. El indicador de intensidad de sellado permitió reconocer a las áreas residenciales cerradas como focos de sellado del suelo.

“…In this study visual photointerpretation of high-resolution images was carried out and eight land-cover types were identified according to the nature of their surfacing material. Some drawbacks related to work at small-size scales are linked to subjectivity in urban unit definition; firstly, due to a lack of image resolution, and secondly, because no common classifications have been established [ 67 ], resulting in different land-cover types depending on the aim of the study. Moreover, the composition of surfacing material cannot be always properly identified with aerial images, so land cover and land use have usually been employed indistinctly to refer to urban units.…”

The University Miguel Hernández of Elche was created in 1996 and its headquarters is located in the city of Elche. A new campus was developed where new buildings and infrastructures have been established for over 25 years in the north of the city. The university is growing, and the land cover/land use is changing, adapted to the new infrastructures. In fact, the landscape changed from a periurban agricultural area mixed with other activities into an urbanized area integrated into the city. The purpose of this work was to evaluate the progressive sealing of the soil and the consequences on the surface hydrology. The area is close to the Palmeral of Elche, a landscape of date palm groves with an ancient irrigation system, which is a World Heritage Cultural Landscape recognized by UNESCO. The evolution of the land occupation was analyzed based on the Aerial National Orthophotography Plan (PNOA). Soil sealing and the modifications of the hydrological ancient irrigation system were detected. Based on the results, proposals for improvement are made in order to implement green infrastructures and landscape recovery that can alleviate the possible negative effects of the soil sealing in the area occupied by the university.

“…Many researchers have worked on studies of the effects of soil sealing in the first six research areas (Lavalle et al 2001;Zhang et al 2003;Blum et al 2004;Van Camp et al 2004;EEA 2006;Montanarella 2007;Tomás et al 2010;Jones et al 2004;García-Alvarado et al 2014), but few of them have researched the last area, archive of archaeological heritage, in any depth, although one of the most important functions of the soil is the preservation of archaeological sites, essential for the study of the history of the earth and of mankind (Blum 2005).…”

Soil sealing (permanent covering of an area by impermeable artificial material) is one of the most serious problems affecting ecosystems in Western Europe. Numerous studies have analysed this issue from an ecological approach, but very few take into account its impact on one of soil’s essential functions, namely the preservation of archaeological sites. Spanish laws on historic heritage (1985) and environmental impact (2013) have tackled the matter by legislating measures for the preservation of heritage. Furthermore, in 1992 Spain signed the Valletta Treaty (the European Convention on the Protection of the Archaeological Heritage) of the Council of Europe, and further ratified it in 2011. Historians, archaeologists and soil scientists should respond to this threat using a multidisciplinary approach. The present study analyses the impact that soil sealing has had on the Roman city of Complutum, located on the Henares River plain (Madrid, España) on highly fertile Fluvisols and Calcisols. One of the aims of this study is to show that the combined use of aerial photos and satellite images provides a continuously updated file of urban development processes and therefore makes it possible to foresee the impact on archaeological sites. At present, medium and high spatial resolution images (Spot and Landsat satellites) can be obtained free of charge and digital processing makes it possible to map any variations in these sites. Another aim of the study is to analyse the importance of soil type and quality in establishing settlements in corridors which have served as important communication routes. There is a greater likelihood of urban planning and development processes in the immediate surroundings of these routes over the years, implying that it is highly probable that pre-existing sites will be destroyed.</p><div> </div>
