L'utilità dell'inutile - The Usefulness of Uselessness - La utilidad de lo inutil
2015
Testo critico sull'esperimento didattico "Inhabiting the Territory" : un laboratorio, esteso tra l’Italia e il Cile, un luogo di elaborazione dell’esperienza diretta, che lavora trasversalmente all’architettura, al design e al paesaggio, per riconoscerne – per contatto così come per differenza – contaminazioni e aderenze, contenuti e concetti, potenzialità e previsioni, e che prova a tenere insieme luoghi distanti, materie impreviste, cultura locale e cultura materiale, la città densa con la campagna estesa e a bassa densità… i Quattro Canti di città, a Palermo e Loanco sull’Oceano Pacifico. È una didattica del pensiero e delle mani, per sperimentare prima di fare, per fare senza aver paura…
Interrelationships between mycorrhizal symbiosis, soil pH and plant sex modify the performance of Antennaria dioica
2010
AM symbiosis is usually beneficial for plants, but the benefits gained may depend on the soil abiotic factors. In dioecious plants, female and male individuals have different resource demands and allocation patterns. As a consequence of these differences, it is logical to assume that female and male plants differ in their relationship with arbuscular mycorrhizal (AM) fungi, although this has rarely been examined. We used a factorial greenhouse experiment to investigate whether female and male plants in the dioecious model species Antennaria dioica have a different relationship with their AM symbionts under two soil pH levels. In particular, we asked: (1) Do the sexes in A. dioica have sex-s…
The Study of the Scale through Space. Teaching Innovation Experience among Architecture Schools: Malaga, Seville and Palermo
2018
The educational innovation project object of this communication focuses on the scale problems that arise in the projects of territorial planning carried out in architecture schools, but also in the loss of the scale concept related to thought and drawing. The project involved collaboration among the Schools of Architecture of Malaga, Palermo and Seville with the aim of carrying out a practical exercise among the students of two subjects that, working on different scales, addressed similar concepts. In particular, following an PBL methodology based on collaborative projects, the planning of the N-340 road in the city of Nerja (Málaga) was carried out. Firstly, the territorial scale is addres…
Assessing drought vulnerability and adaptation among farmers in Gadaref region, Eastern Sudan
2018
Agricultural productivity in rural areas is severely affected by climate variability, and this elevates the vulnerability of rural households to food insecurity. This study examines the socio-economic vulnerability of farmers who are susceptible to droughts in the five agricultural-based regions of Gadaref, Eastern Sudan. A survey was carried out in 500 households to collect data on socio-economic and livelihood indicators. The data analyzed from these indicators were used to generate the three components of drought vulnerability: exposure, sensitivity and adaptive capacity. The analysis revealed that the regions deemed to be most vulnerable to both drought and climate variability were also…

The contribution of the European Society for Soil Conservation (ESSC) to scientific knowledge, education and sustainability
2019
Soil is an integral component of the global environmental system which supports the quality and diversity of terrestrial life on Earth. Therefore, it is vital to consider the processes and impacts of soil degradation on society, especially on the provision of environmental goods and services, including food security and climate change mitigation and adaptation. Scientific societies devoted to soil science play significant roles in reducing soil degradation and promoting soil conservation by advancing scientific knowledge, education and environmental sustainability. The ESSC was founded on 4 November 1988, with the aims to: 1. Support research on soil degradation, soil protection and soil an…
How Universal Is the Relationship between Remotely Sensed Vegetation Indices and Crop Leaf Area Index? A Global Assessment
2016
This study aims to assess the relationship between Leaf Area Index (LAI) and remotely sensed Vegetation Indices (VIs) for major crops, based on a globally explicit dataset of in situ LAI measurements over a significant set of locations. We used a total of 1394 LAI measurements from 29 sites spanning 4 continents and covering 15 crop types with corresponding Landsat satellite images. Best-fit functions for the LAI-VI relationships were generated and assessed in terms of crop type, vegetation index, level of radiometric/atmospheric processing, method of LAI measurement, as well as the time difference between LAI measurements and satellite overpass. These global LAI-VI relationships were evalu…
Corrigendum to “Conservation value of forest plantations for bird communities in western Kenya” [Forest Ecol. Manag. 255 (2008) 3885–3892]
2009
A re-analysis of the bird data revealed a mistake within the database query. Only bird individuals that were heard were integrated in the results leading to lower total richness and number of individuals. In total 115 species and 13,331 individuals were detected of which 41 were forest specialists (43% of all individuals), 40 forest generalists (41%) and 34 forest visitors (16%). The statistical analyses remain very similar. We recorded significant differences in mean bird species richness, number of individuals and relative species richness among the five forest types (Table 1). Multiple pairwise comparisons showed significantly higher numbers of species in natural forest, mixed indigenous…
Arcadio Blasco: : Cinco esculturas urbanas (1986-1991)
2013
Con las primeras elecciones municipales democráticas en España después del franquismo, los nuevos ayuntamientos establecieron programas para reconstruir las ciudades españolas. Un aspecto de estos proyectos fue la creación de espacios públicos donde la gente pudiera encontrarse en un ambiente agradable. Estas áreas se cerraron al tránsito y se amueblaron con árboles, bancos y un nuevo tipo de esculturas artísticas. En la zona de Alicante, el ceramista Arcadio Blasco, ya conocido en Madrid y en Roma, creó cinco monumentos urbanos de gran escala. Después de veinte años, el destino de cada escultura ha sido diferente: alguna permanece en buenas condiciones, pero otras han sido tratadas de tal …
The ‘killer shrimp’Dikerogammarus villosus(Crustacea, Amphipoda) invading Alpine lakes: overland transport by recreational boats and scuba-diving gea…
2013
The alien freshwater amphipod of Ponto-Caspian origin, Dikerogammarus villosus, also known as the killer shrimp, is recognized as being one of the worst invasive alien species in Europe, representing a major conservation problem. Recently, the species has been reported to invade lakes in the Alps in putative association with overland transport linked with recreational activities. This study provided a method to assess risk associated with this overland transport and an opportunity to set up a rationale for effective preventive conservation management. A field survey of 60 lakes encompassing all the Alpine area has revealed the presence of killer shrimp in 12 lakes. Subsequent multivariate d…
