Interwoven landscape

AbstractHuman specie has always engineered the environment to set the conditions for its own settlement, producing in its evolutionary development superorganisms (cities) and the necessary networks of connections among them. Instead of rejecting cars as an extraneous object to a picturesque nature, this project starts from a perspective in which cities and technology are the metabolic extension of human specie and therefore a necessary part of its own nature; the vessels (vehicles) for human transportation, or better, the vehicle-host symbiotic system thus becomes a necessary part of human ecology, and so the network of connections upon which they live, operate and interact with: infrastructures. The project of an environmental enhancer for the Nogara mare highway in Veneto (Italy) provides the unique chance to bring together ecological thinking, host interaction and active materials. Its location (an open country planar area among cultivated fields) enucleates as critical variables the impact of pollutants and the phenomenon of dazzling. With respect to such criticalities, the project uses digital generative and parametric strategies to generate a performative structure in which densification and rarefaction of elements is a local morphological response to dazzle. The structure itself acts as a scaffold for a photo catalytic PET based material that, mimicking the behavior of coccoluti (marine microorganisms) is able to reduce CO2 (and potentially other pollutants) to salts and nitrates that are then naturally deployed to the neighboring cultivated fields as fertilizers. The material has been tested for photo catalytic integration and is currently under development. Present building and production techniques privilege the industrial assembly of inert materials, with a one-way flow of energy and process from raw material to finished product. Instead of this mono-directional energy consumption the project promotes the continuous exchange of information (as code and matter-energy) at all levels and from the digital to the material domains: use of dazzle information, morphogenetic rules and structural behavior to generate the scaffold, a photo catalytic material that responds to pollutants and produces fertilizers, making the structure symbiotic with their hosts and the environment

Traditional knowledge on ethno-veterinary and fodder plants in South Angola: an ethnobotanic field survey in Mopane woodlands in Bibala, Namibe province

Livestock is a critical resource to improve income and household livelihoods in many rural areas. To date, very few studies have investigated farmers’ local knowledge on plants used in managing animal health and welfare in Angolan Mopane woodland. This is a very dry ecosystem where animal husbandry (mostly cattle and goats breeding) is highly widespread and is often the main form of subsidence, greatly contributing to local communities food security, especially in periods of resources shortage. An ethnobotanical research project was carried out in Bibala (Namibe province – Angola) in 2010 – 2012, in order to collect information on different traditional uses of plants, involving an interviewed sample of 66 informants. Fifty-eight of them (87.9%) listed a total of 39 species used as ethno-veterinary and/or fodder plants. Ten ethno-veterinary species (28 citations) were reported by 20 informants as used to treat diseases commonly affecting animals in the studied area, namely respiratory tract problems (Laphangium luteoalbum, Gyrocarpus americanus, Craibia brevicaudata subsp. baptistarum, Lepisanthes senegalensis, Ptaeroxylon obliquum, Ximenia americana) and skin diseases and wounds (Aloe littoralis, Blepharis sp., Ficus thonningii), or acting as a general tonic (Faidherbia albida). Thirty-four plants (235 citations) were cited by 58 informants as fodder. In this category of use, the most cited species were Terminalia prunioides (30 citations), Faidherbia albida (28 citations) and Spirostachys africana (21 citations). Our study shows that communities living in South Angola Mopane woodlands still retain a valuable traditional knowledge about plants used to maintain animal health and welfare. This body of knowledge and related skills can play a crucial role in the resilience of livestock systems facing present environmental and socioeconomic changes

Traditional alcoholic beverages and their value in the local culture of the Alta Valle del Reno, a mountain borderland between Tuscany and Emilia-Romagna (Italy)

BACKGROUND: Traditional alcoholic beverages (TABs) have only received marginal attention from researchers and ethnobotanists so far, especially in Italy. This work is focused on plant-based TABs in the Alta Valle del Reno, a mountainous area on the border between Tuscany and Emilia-Romagna regions. The aims of our study were to document local knowledge about TABs and to analyze and discuss the distribution of related knowledge within the investigated communities. METHODS: Field data were collected through semi-structured interviews. The relative importance of each plant species used to prepare TABs was assessed by calculating a general Use Value Index (UV(general)), a current UV (UV(current)) and a past UV (UV(past)). We also assessed personal experience of use by calculating effective and potential UV (UV(effective,)UV(potential)). A multivariate analysis was performed to compare ingredients in recipes recorded in the Alta Valle del Reno with those reported for neighboring areas. RESULTS: Forty-six plant species, belonging to 20 families, were recorded. Rosaceae was the most significant family (98 citations, 19 species), followed by Rutaceae (15, 3) and Lamiaceae (12, 4). The most important species was Prunus cerasus L. (UV(general) = 0.44), followed by Juglans regia L. (0.38), Rubus idaeus L. (0.27) and Prunus spinosa L. (0.22). Species with the highest UV(current) were Juglans regia (0.254), Prunus cerasus (0.238) and Citrus limon L. (0.159). The highest UV(effective) values were obtained by Prunus cerasus (0.413), Juglans regia (0.254), Rubus idaeus (0.222) and Citrus limon (0.206). We also discuss the results of the multivariate analysis. CONCLUSIONS: TABs proved to occupy an important place in the traditional culture and social life of the studied communities. Moreover, data highlight the local specificity and richness of this kind of tradition in the Alta Valle del Reno, compared to other Italian areas. Some plant ingredients used for TABs have potential nutraceutical and even therapeutic properties that are well known by local people. These properties could constitute an additional economic value for TABs' commercialization, which in turn could promote the local rural economy

Using Medicinal Plants in Valmalenco (Italian Alps): From Tradition to Scientific Approaches

This ethnobotanical survey was carried out in Caspoggio (Valmalenco, SO, Italy) with the purpose of investigating the traditional uses of medicinal plants. Moreover, a bibliographic research meant to validate or refute the uses, focusing on the potentially responsible compounds, was performed. Fifty-nine species, attributable to 30 families (Asteraceae, Pinaceae, Malvaceae, and Lamiaceae the most cited), were mentioned. Arnica montana, anti-inflammatory for traumas and musculoskeletal pains; Pinus mugo, expectorant; Malva sylvestris, anti-inflammatory and soothing; Achillea moschata, digestive. The compounds, responsible for the therapeutic activities, are often polyphenols and terpenoids: helenanin in A. montana, -pinene, -3-carene, and limonene in P. mugo, gossypin and malvin in M. sylvestris, luteolin and apigenin in A. moschata. Scientific evidence for at least one of the traditional activities described was found for 50 species but only in 26 out of 196 works consulted, it is possible to make a comparison between investigated extracts and traditional preparations. This study is thus a stimulus to new phytochemical investigations, mimicking as much as possible the traditional preparations. This work is part of the European Interreg Italy-Switzerland B-ICE project, aimed at creating a management model for the ongoing climate change and searching for new sources of territory valorization as attractions for tourists

Giovanni Sartori e la democrazia della Seconda Repubblica

Il saggio ripercorre e analizza criticamente tutti i passaggi istituzionali della cosiddetta Seconda Repubblica, ossia della peculiare democrazia maggioritaria che si imposta in Italia a partire dal 1994. Tali passaggi sono visti all'interno del pensiero di Giovanni Sartori e in particolare della sua teoria della democrazia. Tale pensiero si è manifestato sia attraverso opere scientifiche sia attraverso una continua attività pubblicistica, in particolare dalle colonne, come editorialista, del Corriere della Sera. Dall'esame di questo pensiero emerge una serrata e continua critica dei caratteri istituzionali della peculiare democrazia maggioritaria all'italiana.The essay traces and critically analyzes all the institutional steps of the so-called Italian Second Republic, that is the peculiar majoritarian democracy that is set in Italy since 1994. These steps are seen within the thoughts of Giovanni Sartori and in particular of his theory of democracy . Such thinking has manifested both through scientific works both through continuous publications, in particular from the columns, as a columnist, of the Corriere della Sera. From an examination of this thinking emerges a close and continuous criticism of the institutional character of the distinctive Italian style majoritarian democracy

Plants and traditional knowledge: An ethnobotanical investigation on Monte Ortobene (Nuoro, Sardinia)

<p>Abstract</p> <p>Background</p> <p>Most of the traditional knowledge about plants and their uses is fast disappearing as a consequence of socio-economic and land use changes. This trend is also occurring in areas that are historically exposed to very few external influences, such as Sardinia (Italy). From 2004 to 2005, an ethnobotanical investigation was carried out in the area of Monte Ortobene, a mountain located near Nuoro, in central Sardinia.</p> <p>Methods</p> <p>Data were collected by means of semi-structured interviews. All the records – defined as 'citations', i.e. a single use reported for a single botanical species by a single informant – were filed in a data base ('analytical table'), together with additional information: i.e. local names of plants, parts used, local frequencies, and habitats of plants, etc. In processing the data, plants and uses were grouped into general ('categories') and detailed ('secondary categories') typologies of use. Some synthetic indexes have also been used, such as Relative Frequency of Citation (RFC), Cultural Importance Index (CI), the Shannon-Wiener Index (H'), and Evenness Index (J).</p> <p>Results</p> <p>Seventy-two plants were cited by the informants as being traditionally used in the area. These 72 'ethnospecies' correspond to 99 botanical taxa (species or subspecies) belonging to 34 families. Three-hundred and one citations, 50 secondary categories of use, and 191 different uses were recorded, most of them concerning alimentary and medicinal plants.</p> <p>For the alimentary plants, 126 citations, 44 species, and 13 different uses were recorded, while for the medicinal plants, there were 106 citations, 40 species, and 12 uses. Few plants and uses were recorded for the remaining categories. Plants and uses for each category of use are discussed. Analyses of results include the relative abundance of botanical families, wild vs. cultivated species, habitats, frequency, parts of plant used, types of use, knowledge distribution, and the different cultural importance of the species in question.</p> <p>Conclusion</p> <p>The study provides examples of several interesting uses of plants in the community, which would seem to show that the custom of using wild plants is still alive in the Monte Ortobene area. However, many practices are no longer in use, and survive only as memories from the past in the minds of elderly people, and often only in one or just a few informants. This rapidly vanishing cultural diversity needs to be studied and documented before it disappears definitively.</p
