CAP POLICY DIMENSIONS: A CATALYST FOR COLLABORATION AND SUSTAINABLE CHANGES
2015
A great challenge to EU livestock production markets is the growing production price and the farmers' income variability. The public request for traceability and accountability determined the EU agri-food policy to implement new sustainable reform. In this paper the author identified a set of inputs and impacts of CAP sustainable reform on livestock system.International major competitors are assessed to benchmark the competitiviness of EU agri-food industry.
Requalification of the Tobacco Factory in Palermo with destination to social finalities
2016
From the Sixties and for many years later the construction of new buildings, both public and residential, has made our cities more and more large, with a great squandering of ground, pollution and reduction of the green areas. A necessary trend reversal has implied a growing interest towards the rehabilitation and requalification of the brownfields. These, both inside the urban fabric and in suburban areas, offer complexes of buildings with great potentiality for a sustainable reuse both from the social point of view and from the environmental one. The large dimensions, the great spans and the materials usually used make these buildings suitable to a recovery which makes possible a rehabili…
Mycorrhizae in crop production
2007
International audience; It has been a revelation that, strictly speaking, most plants do not have roots but rather mycorrhizae, a fact that has had tremendous consequences on the life of plants and the evolution of soil-plant systems. The research on arbuscular mycorrhizal (AM) symbioses has been intensive over the past forty years and we have learned a lot on the physiology, biology, ecology, and genetics of the symbiosis and the fungi involved in it. Most important, it appeared that cropping systems could be more sustainable with the management of AM fungi and reduced reliance on agrochemicals. The extraradical mycelia of AM fungi are an essential link between the plants, which are the co…
PROMOTION OF ECOLOGIC PRODUCT CERTIFICATION AS INSTRUMENT TO SPEED UP THE ECOLOGIC AGRICULTURE
2014
This paper present a vision about the possibility to speed up the conversion process to an ecological agriculture in Romania. The link from ecological products consumer and ecologic agricultural producer is also explained from point of view of certification process. Presenting the consumer mentality and principles and rules of organic farming and certification can open the way to a sustainable and ecological agriculture.
Institutional arrangements for sustainable development: Cases from the Navarra Province (Spain).
2015
After more than 20 years of the Earth Summit, Sustainable development is still recognized as one of the main challenges of the XXIst century. World leaders are putting new emphasis on the need to resolve urgent environmental challenges underlining their link with the wellbeing of humankind and the very conditions that made life possible on the planet. We are immersed in complex socio-ecological systems where sectoral or simplified responses are not adequate. A more systemic vision is imperative to effectively address the challenges faced. New approaches are being developed to integrate social, environmental and economic concerns in all human activities. Particular attention is given to deco…
Wybrane problemy zrównoważonej intensyfikacji rolnictwa na przykładzie badań w województwie opolskim
2017
Celem opracowania jest identyfikacja problemów związanych z wdrażaniem w gospodarstwach rolnych województwa opolskiego strategii zrównoważonej intensyfikacji. Materiał pierwotny do badań zebrano w 2014 roku metodą wywiadu kwestionariuszowego w 100 celowo dobranych gospodarstwach rolnych o powierzchni powyżej 10 ha UR w subregionach reprezentatywnych dla rolnictwa regionu. Na podstawie badań stwierdzono, że rolnicy najczęściej wybierają trajektorię rozwojową, polegającą na powiększaniu areału posiadanej ziemi, przy jednoczesnym dostarczaniu dodatkowych usług środowiskowych. W opinii badanych rolników regulowana normami środowiskowymi intensyfikacja produkcji rodzi potrzebę ciągłego uczenia s…
Culinary Tourism. A New Trend on the Tourism Market
2017
Seen as a new form of manifestation of the behavior of the consumer of tourism products and services, culinary tourism has recorded an ascending trending the last years, with a positive forecast for the following years. A possible explanation for this phenomenon is the orientation and encouragement of the tourist services providers to adopt regional development strategies that harness traditional local resources and products in a context where the contemporary consumer no longer only pursues the acquisition of products and services to meet their needs, but also looks forward to new experiences that are a delight for the senses. Against this background, the present paper aims to highlight so…
Studio di fattibilità per la definizione di azioni ed interventi per il sistema turistico e per lo sviluppo delle filiere produttive dell'ambito terr…
2007
Lo studio individua le attività manifatturiere e del commercio distinte in principali e secondarie. Si passa poi all’individuazione e localizzazione dei prodotti tipici e locali collegabili al sistema ospitale. Nella parte II viene effettuata un’analisi della domanda turistica. Nella parte III, infine, si passa all’analisi strategica del territorio sviluppando una Swot Analysis strettamente centrata su un turismo escursionistico con prevalente connotazione eno-gastronomica. Da tutto ciò, scaturiscono le possibili azioni strategiche per lo sviluppo del sistema turistico e delle filiere produttive collegabili alla domanda turistica. L’analisi volta ad accertare le principali caratteristiche r…
Poincare Inequalities and Spectral Gap, Concentration Phenomenon for G-Measures
2002
We produce a new approach based upon inequalities of Poincare’s type for giving constructive estimates of the mixing rate for a family of mixing stationary processes continuously depending on their past called g-measures. We establish also exponential inequalities of Hoeffding’s type leading to a concentration phenomenon for a large class of observables; this last property permits in particular to give the typical behaviour of the n-orbits of a g-measure.
Constant inner potential DFT for modelling electrochemical systems under constant potential and bias
2021
Electrochemical interfaces and reactions play a decisive role in e.g. clean energy conversion but understanding their complex chemistry remains an outstanding challenge. Constant potential or grand canonical ensemble (GCE) simulations are indispensable for unraveling the properties of electrochemical processes as a function of the electrode potential. Currently, constant electrode potential calculations at the density functional theory (DFT) level are carried out by fixing the Fermi level of the simulation cell. However, the Fermi level from DFT calculations does does not always reflect the experimentally controlled electrode potential or describe the thermodynamic independent variable in G…
