I paesaggi agrari tradizionali dell’albero: il significato moderno di forme d’uso del suolo del passato
No full textItaly represents one of the most suitable
environment for fruit trees and vines and since the origin
of their domestication and introduction in extremely
varying environments, depending on the species
adaptability and local culture, a complex mosaic of
landscapes has been originated by Nature, farmers or
gardeners. In the study of the landscape it must be
considered that the relationship between fruit trees or
vines and landscapes represents a precious aspect of
the Italian culture and has been studied by History,
represented in Art and Literature, analyzed by science
like Architecture and Agronomy, but at first has been
created by Agriculture. Owing to the evolution of the
relationship land and farmers, the development of
agricultural practices, the change of marked requirements
and objectives, different agricultural landscapes
have been created, each having an unique
meaning and functions. Nonetheless, the physiognomy
of tree cropping systems has changed rapidly
starting from half of the past century because of the
introduction of new genetic resources, the change in
the meaning of the product’s quality, the industrialization
of the agronomic technique. These recent developments
have turned out in loss of landscape diversity,
biodiversity erosion, environment resources depletion.
The actual physiognomy of the Italian countryside,
from the plan to the most represented mountain
areas, is characterized by modern and traditional agricultural
landscapes, not even distinguished, frequently
overlaid. They represent the “forms” of the today’s
arboriculture visible in the historic and contemporary
gardens, in the remnants of the coltura promiscua, in
the polycultural growing systems, as well as in the
specialized orchards. The contemporary landscape of
fruit trees and vines witnesses its history, characters
and functions particularly in terms of biological and
environmental diversity maintenance. This review is
focused on the traditional fruit tree and vine’s landscapes
still well rooted in the Italian agricultural landscape,
but differently conserved, managed and perceived.
The aim of the historical excursus is to go
through their development phases and to underline
the changing functions. A survey of the multifunctionality
recognisable in the traditional agricultural landscape,
in particular their role in the preservation of
environmental resources, agro-ecosystems functionality,
landscape diversity and cultural memory justifies
the interest in the preservation and valorisation of
these productive landscapes and of the traditional
agricultural techniques, thank to which they are maintained.
The preserving strategies adopted in the
European countries as well as the modern study
approaches based on multidisciplinary methodologies
are also analysed
I Paesaggi Agrari Tradizionali: Introduzione.
No full textIl volume propone un percorso di studio dei Paesaggi
Agrari Tradizionali (PAT), seguendo alcune
tracce interpretative dei processi di trasformazione che
hanno modificato il paesaggio agrario italiano e il suo
ruolo ambientale, culturale, economico e sociale. Tali
temi sono trattati attraverso un approccio segnatamente
interdisciplinare, inteso come presupposto indispensabile
all’analisi, alla comprensione e all’interpretazione
delle dinamiche evolutive dei contesti rurali. Gli autori
del volume, nell’ambito del lavoro condotto dalle
singole unità di ricerca, hanno contribuito in modo
coordinato e complementare alla definizione del percorso
teorico e metodologico, pur all’interno di riferimenti
concettuali e strumenti analitici propri dei rispettivi
ambiti disciplinari: dall’arboricoltura, all’ecologia
del paesaggio, all’economia agraria
Light enhances differentiation of the vascular system in the fruit of Actinidia deliciosa
No full textLight is recognized as crucial in determining high quality of fleshy fruits, for example, kiwifruit [Actinidia deliciosa var. deliciosa (A. Chev.) C. F. Liang et A. R. Ferguson]. Among the possible mechanisms through which light improves the quality of kiwifruit berry, there may be a direct morphogenic role on the differentiation of the fruit's vascular system, though this has not yet been investigated. The present study's aim was to determine (1) whether light positively affects the differentiation of the vascular system of the fruit and/or the pedicel, and, if so, (2) which component (xylem, phloem, or both) is more affected, and (3) in which period of the berry's development the improvement of the vascular differentiation (if any) occurs. To this end, fruit morphogenesis of kiwifruit was studied in two developmental environments (i.e., in full sunlight and in paper bags that reduced the full sunlight to 10%), and in two phases of fruit development (i.e., 1 and 5 months [harvest] after anthesis). During the growth period, the type of environment did not affect the differentiation pattern of the vascular system in the three types of bundles present in the fruit. However, in comparison with shade, light improved the vasculature in the fruit pericarp and pedicel, inducing a consistently higher extent of the xylary component in the main bundles of the fruit and pedicel, principally due to an increase in the number of xylem elements. The phloic component was also increased by light, but to a much lesser extent than that of the xylary. During the entire period of development, light-grown fruits contained higher concentrations of calcium and magnesium, as compared with shade-grown fruits. In conclusion, in the berry of Actinidia deliciosa, light enhances the differentiation of the vascular system, in particular the xylary component. The hypothesis that fruit quality is improved through a more efficient translocation of specific mineral nutrients (e.g., calcium) via the xylem is presented
Agricolture urbanizzate per nuovi paesaggi metropolitani
No full textLe “Agricolture urbanizzate” sono l’insieme di pratiche e sperimentazioni variamente connesse alla multifunzionalità agricola nei territori della diffusione insediativa.
Il lavoro di tesi delinea una strategia di paesaggio come modalità di lavoro concreta e ripetibile per la messa a punto di questi nuovi paesaggi metropolitani, forme innovative di equilibrio tra politica, agricoltura e comunità, e occasione di sperimentazione d’iniziative di Innovazione sociale.
La proposta scaturisce da un’originale disamina sull’attuale “grado di fertilità” delle teorie di paesaggio di Richard Ingersoll e Pierre Donadieu rispetto a soggetti, spazi, comportamenti e politiche coinvolti nella descrizione di una possibile geografia contemporanea delle relazioni città/campagna. La valorizzazione dei contesti metropolitani locali quale obiettivo della strategia presuppone il rifiuto di una visione vincolistica del progetto di paesaggio e lo svolgimento di Laboratori di progettualità sociale, azione-chiave per la costruzione delle nuove Agricolture Urbanizzate. La Green Infrastructure è assunta come vero e proprio “dispositivo di sistema” della strategia, strumento di progetto duttile e declinabile in grado di superare i problemi di frammentazione spaziale, funzionale, e amministrativa della città contemporanea. La proposta s’inquadra nello scenario economico relativo al Periodo di Programmazione Europea 2014-2020.This thesis outlines a landscape strategy for what the author defines “Urbanised Agricultures”, and signifies a set of practices and experimentations variously associated with multifunctional agriculture, the latter being a target of European policies since years.
The expression landscape strategy defines an assemblage of policies and local actions able both to restore and enhance peculiarities and dissimilarities of local metropolitan contexts (including their environmental, economic and social resources) and to fuel a new sociality, green economies, and innovative spatial configurations suitable for contemporary living needs.
The thesis sketches a landscape strategy which does not coincide with an a priori pre-figuration of space. It is rather a tool to manage ordinary territorial transformations and to hold together a variety of heterogeneous but coherent interventions, mutually conditioning. These interventions can be implemented through different actions and through the involvement of public and/or private entities, at different times. For this reason, although conceived for the territory of Rome, the landscape strategy here proposed is of general interest: it can be adapted and repeated in other European metropolitan areas. Three essential features characterise the landscape strategy:
- Peculiarities and differences for new Urbanised Agricultures (goals). “Peculiarities” and “differences” refer to the set of potential and needs expressed by a specific local community. Spaces, agents and activities are three categories used to interpret the metropolitan landscapes in relation to new Urbanised Agricultures. This interpretation is carried on in the light of “multifunctionality”, which guarantees an overall protection of rural land assumed as a collective good. Multifunctionality can be expressed through complex shapes, able to adapt to various contexts enriching their own specificities;
- System devices for new Urbanised Agricultures: green infrastructures (tool). The landscape strategy proposed by the author overcomes spatial, functional and administrative fragmentation of the contemporary city proposing green infrastructures as a “system device”. A green infrastructure can adapt to each territory’s specificities as a result of its network structure and its mutable structure, and can concentrate a set of very different spaces back to a single, coherent project system (spaces different for protection system, property rights, transformation potential, economic and financial opportunities, capability in providing ecosystem services, etc.);
- Social designing for new Urbanised Agricultures (actions). The landscape strategy does not impose any binding role to the project, and identifies the members of a community both as beneficiaries and as producers of their own life context; consequently, the landscape strategy proposes to conduct “Workshops of social designing” as key actions to define new Urbanised Agricultures. Workshops represent the place where an operational dialogue about current relations between rural and urban systems opens by using a project proposal. The goal is to build a network of individuals who share a co-responsibility in the production and management of their landscape, in relation to new job opportunities and new collective benefits (social, cultural and economic benefits, improvements in time organisation, enlarged welfare, etc.).
Structure of the research. The research is divided into three parts. Each part pursues “autonomously” a specific purpose but all converge towards the same direction – albeit in different ways – namely the definition of the landscape strategy.
- Part I. Modern evolutionary characters of urban/rural relationship (Concepts). The first part of the thesis aims at presenting the latest developments in the urban/rural relationship, by assuming three different points of view: organisation of rural society, urban planning, and town planning legislation. These three thematic interpretations show how city and countryside are two sides of the same evolution, outlining the historical and cultural transformation of fundamental concepts still detectable both in current dynamics (subjects of Part II), both in contemporary designers’ landscape theories (addressed in Part III);
- Part II. Contemporary geography of urban/rural relationship (People/tendencies/actions). The second part of the thesis intends to delineate a possible geography of contemporary relationships between cities and countryside. The resulting “map” emerges by the analysis of individuals, spaces and activities related to agricultural practices carried out in urban areas and noticeably relevant for their potential benefits to the city (these practices are already object of several urban policies in the realm of Europe 2020 Strategy). This study tends to demonstrate how the definition of more equitable and sustainable urban paradigms in metropolitan contexts passes through experimenting new forms of local-based multifunctional agriculture;
- Part III - Landscapes in progress: interpretations and proposals (critical comparative assessment and project proposal). The third part of the thesis aims to define a Landscape Strategy (goals, tools and actions) to foster new forms of Urbanized Agricultures for supporting local communities in metropolitan areas. A critical analysis of a series of landscape case studies allowed an investigation of the degree of fertility of Pierre Donadieu’s and Richard Ingersoll’s landscape theories. The examination highlights a sequence of elements able to support “potential projects” and which the author reorganised, re-interpreted and conveyed in a strategy for new metropolitan landscapes. This strategy understands a re-balance of urban-rural relations as an opportunity for experimenting initiatives of social innovation
