Agriculture urbaine et quartiers populaires. Livre blanc. Issu de la rencontre « Agriculture urbaine et quartiers populaires » organisée le 19 novemb…
2022
Ce document fait suite à la journée d’étude « Agriculture Urbaine et Quartiers Populaires » organisée le 19 novembre 2019 à l’Université Paris 8. Organisée à l’initiative de chercheuses (Ladyss et Pleïade) et de l’Institut Paris Région, cette journée a suscité un vif intérêt de la part de personnes qui pratiquent l’agriculture urbaine (associations ou professionnels) et des acteurs et actrices de l’aménagement et du développement social. Elle a rendu visible l’émergence d’un véritable mouvement social pour la transformation des quartiers populaires par l’agriculture urbaine. Il nous a semblé important de témoigner de cette dynamique et d’y contribuer par la rédaction de ce livre blanc, pens…
La filiera dell’agricoltura biologica in Sicilia: ruolo della GD e variabilità dei prezzi dei prodotti bio nella città di Palermo

The decline of the cork oak growing in Sicily is accompanied by the loss of the functions proper to agroforestry systems
2021
The cork oak is one of the most important tree species in the Mediterranean basin, where it covers more than 2 million hectares. Among evergreen oaks, Quercus suber stands out for the variety of cultural systems in which it has been successfully employed, including typical agroforestry systems. Accordingly, a wide range of ecosystem services may be associated to cork oak, including the preservation of biodiversity, carbon sequestration and forage production. In the Mediterranean, the cork oak represents a key species for many natural and seminatural landscapes and habitats, as well as playing a prominent role for the economic and social development of local communities. However, there is in…
The polarization of European agriculture: spatial and dynamic features within a non parametric framework
2009
We present a study of the polarization of European agriculture at NUTS2 regional level. The analysis of selected indicators focuses on spatial and dynamic features of distributions. We make use of the non parametric technique of stochastic kernel which allows to explore the features of a whole distribution and to point out the clustering of statistical units.

Le filiere del sistema agricolo per l'energia e l'efficienza energetica
2011
Increasing the use of renewable energies and Energy Efficiency offer significant opportunities for Italy to reduce fossil energy, greenhouse gas emissions and secure its energy supply. This report presents a brief analysis of the most important supply chains of the Agriculture system. Greatest attention is paid to the significant role that agriculture and its supply chains are likely to play in terms of bioenergy production and energy saving. Special attention is devoted to new agricultural activities like those associated with the reduction of vegetable food waste, the agrotourism, the urban agriculture, the plastic coverings and the greenhouses, the plant protection and the fertilizers. D…
Stochastic kernel and conditioning schemes: a study about the influence of spatial factor on agriculture of EU NUTS2
2009
Besides to be an useful methodology for the detection of distribution dynamics of indicators, stochastic kernel has been generalized to a regression-like rationale (Quah, 1997). The latter allows to determine how a distribution is influenced by a "factor", through a "conditioning scheme" which is a set of rules stating how the original distribution is altered in order to obtain its "conditioned" version. This paper aims to study the influence of the "spatial factor" on distributions of selected agriculture impact indicators across EU NUTS2. The present work offers an empirical analysis of dynamics of selected indicators of agriculture across NUTS2. Our scope is to give an overlook of EU ter…
Sustainable Agriculture Management in European Union Countries
2020
The contemporary agriculture facing not only challenges in the form of higher efficiency, productivity or consolidation, but also it should fulfill certain criteria, related to sustainable development concept. In these days the management of agriculture sector should take into account, not only the economic, but also the ecological aspects. Taking account that agriculture is one of the most important activities in EU countries, the purpose of the article was to outline the present management of agriculture from sustainable development point of view. The methodology used adopted the form of comparative analysis conducted for chosen agri-environmental indicators. Based on Eurostat statistics …
Combined effect of crop rotation and carabid beetles on weed dynamics in arable fields
2020
AbstractWeed management is a resource-intensive practice in arable agriculture, with direct and long-term impacts on both productivity and biodiversity (e.g. plant, pollinators and farmland wildlife). In conventional systems, weed control relies on crop management and herbicide inputs, but for more sustainable production systems, use of herbicides needs to be reduced. This requires a good understanding of the processes that regulate arable weed dynamics in arable fields.We adopted a systems framework to understand and model interacting components that drive the weed dynamics in 168 arable fields. Within this framework, we built a structural equation model (SEM) to quantify the direct and in…
