La città verde
No full textIl tema della “città verde” è oggi indissolubilmente legato all’idea di bioarchitettura, da un lato, e di città sostenibile, dall’altro. “Città verde” è il titolo di un concorso di architettura del 1929 per la costruzione di una città del riposo nei pressi di Mosca che produsse quattro progetti di maestri dell’avanguardia russa che fecero del tema il pretesto per la proposta di nuove tipologie insediative. In questo libro, il termine “città verde” riunisce una serie di esperienze che, come quei quattro progetti, hanno cercato di delineare una nuova tipologia insediativa strutturalmente fondata nella campagna e nel territorio e alternativa alla grande città come forma di habitat per lo sviluppo della società moderna.
Il libro è diviso in due parti. La prima parte, "La città verde", scritta dall'autore - è composta da sei saggi in cui attraverso il confronto tra quattro esperienze di progettazione di insediamenti fondati sul territorio e complementari alla città negli anni '30 e '40 del Novecento: tra Russia (Il concorso per la "Città verde di Mosca" e il disurbanesimo), Italia (La campagna padana di Gaetano Ciocca) e Stati Uniti (I progetti per gli insediamenti TVA). Nei casi di studio vengono delineati gli elementi tipici di una forma insediativa complementare alla grande città, con le sue tipologie architettoniche distintive. La rassegna si conclude con un capitolo finale sulle caratteristiche del progetto di "città verde" desumibili dal confronto tra casi di studio che apre la seconda parte del libro. La seconda parte, “Per un atlante delle città verdi”, redatta da autori invitati e specialisti - è composta da sei saggi che propongono una rilettura di noti casi di architettura moderna in chiave di progetto di “città verde”: dalla visione fisiocratica negli Stati Uniti (Thomas Jefferson, M. C. Loi) e in Francia (Claude N. Ledoux, D. Chizzoniti); alle cittadelle industriali modello negli Stati Uniti (Henry Ford, F. Bucci) e in Italia a Ivrea (Olivetti, F. Bonfante); alle visioni del secondo Novecento di nuove forme insediative fondate sul territorio in Italia (“ruralistica” di Amos Edallo, G. Frassine; “l’eco-città” di Marcello D’Olivo, G. L. Ferreri).
Il volume si apre con una prefazione di Guido Canella e si chiude con una postfazione di Jurij P. Volchok. Nel dare il profilo di ciascuna delle esperienze citate, tutti gli autori dei diversi contributi hanno di volta in volta teso a evidenziarne soprattutto la proattività in termini di discorso architettonico e di progettazione insediativa. Le “città verdi” che compongono il libro sono frutto di ricerche svolte dagli autori nell’ambito di dottorati di ricerca e per progetti europei (COST C 11) e MIUR presso il Dipartimento di Progettazione Architettonica del Politecnico.The theme of the “green city” is today inextricably linked to the idea of bio architecture, on the one hand, and of a sustainable city, on the other. “Green City” is the title of a 1929 architectural competition for constructing a city of rest near Moscow that produced four projects by masters of the Russian avant-garde who made the theme the pretext for the proposition of new settlement typologies. In this book, the term “green city” brings together a series of experiences that, like those four projects, have sought to outline a new settlement typology structurally founded in the countryside and in the territory and alternative to the big city as a form of habitat for the development of modern society.
The book is divided into two parts.
The first part, "The Green City", written by the author - consists of six essays in which through a comparison between four experiences of planning settlements founded in the territory and complementary to the city in the 30s and 40s of the twentieth century: between Russia (The competition for the "Green City of Moscow" and disurbanism), Italy (the Po Valley countryside of Gaetano Ciocca) and the United States (the projects for the TVA settlements). In the case-studies, the typical elements of a form of settlement complementary to the large city are outlined, with its distinctive architectural types. The review ends with a final chapter on the characteristics of the "green city" project deducible from the comparison between case studies that opens the second part of the book. The second part, “For an atlas of Green Cities”, written by invited authors and specialists - consists of six essays that propose a rereading of well-known cases of modern architecture in the key of the “green city” project: from the physiocratic vision in the United States (Thomas Jefferson, M. C. Loi) and in France (Claude N. Ledoux, D. Chizzoniti); to the model industrial citadels in the United States (Henry Ford, F. Bucci) and in Italy in Ivrea (Olivetti, F. Bonfante); to the visions of the second half of the twentieth century of new forms of settlement founded in the territory in Italy (“ruralistica” by Amos Edallo, G. Frassine; “the eco-town” by Marcello D’Olivo, G. L. Ferreri).
The volume opens with a preface by Guido Canella and closes with an afterword by Jurij P. Volchok.
In giving the profile of each of the experiences cited, all the authors of the different contributions have from time to time tended to highlight above all the proactivity in terms of architectural discourse and settlement design. The "green cities" that make up the book are the result of research carried out by the authors in the context of research doctorates and for European projects (COST C 11) and MIUR at the Department of Architectural Design of the Polytechnic
Factors affecting habitat occupancy and densities of the Red-legged partridge in introduction areas of north-western Italy
No full textIntroduction. The Italian range of the red-legged partridge changed markedly in the time together with
population abundance because of habitat changes, overhunting, and releases of hand-reared birds. Currently
self-sustaining populations are recorded in plain areas outside the historical range that possibly originated by
natural colonization and/or introductions carried out with partridges from game farms. . Historic range of red
legged partridge in Italy extended mainly along the northern Apennine chain from the Southern Alps to the
west, to the province of Modena in Emilia-Romagna region to the east, both on the south and north slopes. In
central Italy the presence of the species was recorded in Tuscany, Umbria and Marche regions, approximately
down to the Mount Vettore (29 provinces and 8 regions). In the years between 1980 and 1990 the red legged
partridge was present in 18 provinces and 5 regions. The populations in central Italy disappeared with the
exception of the Elba Island, and a strong decline and local extinctions were recorded for the population in
northern Apennines. On the contrary massive releases of hand-reared partridges from the game farm of the
region Emilia-Romagna caused an increase of the eastern part of the range that reached the provinces of
Bologna, Ravenna, and Forlì-Cesena [1]. At the end of the past century, the hunting districts established by the
National Law 157/92 and private estates carried out releases of red legged partridges from game farms outside
the historical range causing an important range expansion, in particular in the Po plain and in central Italy (39
provinces and 9 regions).
Methods. To collect information on the factors affecting the current distribution and abundance of red-legged
partridge in new-colonized areas we carried out call spring counts in two (2015) and three (2016) protected
areas located in the dry crop Po plain in the Piacenza province. The three study areas covered 9.2 (Borgonovo
study area), 41.1 (Trebbia s. a.), and 35.6 km2 (Nure s. a.). They were mainly cultivated; the main crops were
winter cereals (18.9%), maize (11.9%), vegetables (7.6%), alfalfa (7.0%) and hay fields (5.0%). Settlements
occupied 10.7% of the study areas. Two main streams cross Trebbia and Nure study areas with pebbly shores
occupying in total 20.0% of the surface. We carried out call counts with tape recorded call from random
listening points (34 points in 2015 and 92 in 2016) in April and May from the sunrise until 9.30 a.m., recording
the calling males of partridges and pheasants [2]. The densities were calculated using a 300 m fixed radius
from the points. Moreover in each buffer of 300 m we calculated the percentages of the main land use classes
and the main landscape metrics. We analyzed habitat selection by red-legged partridges by means of
Resource Selection Probability Functions (RSPF) formulated by Binary Logistic Regression Analyses (BLRA) of
presence points vs. an equal number of random points in which we calculated the same habitat variables (use
vs. availability approach, [3]). Moreover we examined the effect of habitat variables on the partridge density by
Multiple Regression Analyses (MRA) carried out considering only the presence points. For both analyses we
selected the best models by the correct Akaike Information Criterion (AICc) [4]; the performance of logistic
model was tested by ROC analysis and that of multiple regression model by the correlation between the
predicted and observed values. We verified the multicollinearity of predictor variables by the Variance Inflation
Factor (VIF), the normality of residual distribution by the Kolmogorov-Smirnov test, and the residual
autocorrelation by Durbin-Watson test [5].
Results. The average density varied from 2.1 (SE=0.42) to 3.2 (SE=0.39) in 2015 and from 2.9 (SE=0.63) to
3.7 (SE=0.88) in 2016 without significant differences between years and study areas. For 15 habitat variables
we found significant differences between presence and control points (Mann-Whitney U test, P<0.05); in
particular winter cereals, pebbly shores, hedgerow density, Shannon diversity index, the patch number, edge
density, and mean perimeter area ratio had greater values in presence points. Three habitat variables (winter
cereals, pebbly shores and habitat diversity) entered the best logistic model with a positive effect on the
presence probability of red-legged partridge. The model explained 37.0% of the variance and correctly
classified 71.2% of the original cases (presence: 77.8%; controls: 64.9%); ROC analysis showed a good
performance of the model (AUC=0.82, SE=0.048, P<0.0001) (Table 1). We found significant positive
correlations between the partridge density and percentage of unpaved roads (study areas pooled r= 0.442,
n=39, P=0.005), hedgerows (Trebbia study area r=0.661, n=16, P=0.005), hay fields (Trebbia s. a. r=0.601,
268
n=16, P=0.013), and patch size SD (Nure s. a. r=0.648, n=13, P=0.017).Considering the study areas pooled
the best regression model explained 31.8% of the density variance by the inclusion of four habitat variables of
which the percentage of unpaved roads, and the edge density with significant positive effects, and the patch
number with negative ones (Table 2); predicted and observed density values were highly correlated (r=0,624;
n=39; P<0.0001).
Discussion. The expansion and shift of the species range occurred mainly because of releases carried out in
recent times by hunting districts leading to the occupancy of unsuitable areas (irrigated plain) by unstable or
low density populations. Low density populations can survive in dry crop plain and low hills characterized by
high crop diversity and by the traditional rotation farming. Favourable characteristics are: prevalence of winter
cereals (rotational crops), medium presence of hedgerows and tree rows, presence of river with large pebbly
shores, unpaved road network, high habitat diversity, small field size, high landscape patchiness and
complexity, and low pheasant density. Based on these characteristics it would be possible to identify suitable
areas outside the original range to plan species introductions with partridges from game farms free from
hybridization with Alectoris chukar. This can lead to the recovery of the species by putting it safe from the
habitat losses in the historical range that can be considered the main threat for red-legged partridge
conservation
Density and habitat requirements of red-legged partridge on Elba Island (Tuscan Archipelago, Italy)
No full textThe red-legged partridge (Alectoris rufa, Linnaeus 1758, Phasianidae) is a common game bird in Europe and it is classified as SPEC 2 (Species of European Conservation Concern), that is, a species with unfavorable conservation status due to a marked population decline. Loss of suitable habitat and hunting management are considered among the major causes of its decline. Such a decline can be also related to agriculture intensification, changes in agricultural practices and the abandonment of less productive lands. Habitat suitability models are an important management tool to define the potential distribution range of a given species, design a protected area network, and plan appropriate management actions and evaluate their effects. This study was conducted on Elba Island (Tuscany) in spring 2011 to define the habitat factors that affect the A. rufa distribution in a typical Mediterranean landscape. On this island the species is declining, as it is in other areas of Europe. We carried out point counts in a survey stratified according to vegetation. We formulated Resource Probability Selection Functions following a presence vs. availability design by Binary Logistic Regression Analysis to obtain a map of potential distribution of the species. We observed that the red-legged partridge distribution was mainly linked to the natural habitat with garrigue and perennial meadows, whereas woody landscape had a negative effect. To stop the species decline on the island habitat improvement actions are needed, such as the cutting of dense vegetation to create open areas

L'articolo prende in esame l'opera di Leone Carpi Il Risorgimento italiano, pubblicata a puntate mensili tra il 1884 e il 1888, e ne analizza il progetto ispiratore, riconoscendo in quest'opera uno dei primi tentativi di costruire una memoria risorgimentale di tipo conciliativo, sia in relazione alla ripartizione regionale degli «eroi» del Risorgimento, sia per quanto attiene alla loro estrazione sociale e alla loro collocazione politica.
Questo tentativo trae origine dall'esigenza - caratteristica di fine Ottocento - di dare linfa a un nuovo aggressivo nazionalismo di massa, idoneo ad aggregare attorno al pubblico potere attraverso il culto della patria gruppi sociali sin lì emarginati sotto il profilo del godimento della cittadinanza politica.Meriggi Marco.
