Land use functions — a multifunctionality approach to assess the impact of land use changes on land use sustainability
2008
Part 5. Regional and local evaluation - 17; International audience; The dramatic changes in land use observed in Europe in the last fifty years have generally resulted in improvement of human welfare and economic development. On the other hand, they have caused serious environmental problems. There is therefore a need for approaches that help to understand in an integrative way the economic, environmental and societal impacts that land use changes have on sustainability. Sustainability Impact Assessment(SIA), which assesses the impact of policies on sustainability, addresses this challenge. SIA partly builds on the concept of the multifunctionality of land which helps to deal with the compl…
Variation of post-dispersal weed seed predation according to weed species, space and time
2008
International audience; Post-dispersal seed predation is an important source of mortality in plant populations. If this phenomenon is better known in tropical and woody systems, information is lacking for weeds in French agrosystems. In this paper, we evaluated seed predation variability in an organic wheat field by conducting experiments on weed seed preference and on spatial and temporal variation in predation rates. Weed seed predation preferences followed a species rank: Viola arvensis = Stellaria media > Alopecurus myosuroides = Chenopodium album > Sinapis arvensis = Anagallis arvensis = Galium aparine > > Plastic globules (for control), with weekly mean predation rates between 19 and …
Conséquences de l’utilisation de variétés de tournesol tolérantes aux herbicides sur la flore des agrosystèmes
2022
The farming practices associated with the use of sunflower herbicide-tolerant varieties (HTVs) have raised concerns among public authorities, who have recommended monitoring the potential effects of HTVs on biodiversity. In this context, at the scale of three French departments, the vegetation of 239 sunflower fields and their margins was studied between 2017 and 2019. This lower weed diversity can be attributed to shorter crop rotations and higher herbicide use. Admittedly, the higher densities of A. artemisiifolia observed in plots with HTVs are the cause of the use of these varieties rather than the consequence of these practices. However, these practices do not seem to solve the problem…
A genre and a limit: Across the Rio Grande border: A study of Tommy Lee Jones' 2005 film "The Three Burials of Melquiades Estrada"
2010
Attempting to answer the deceptively simple question of how far Tommy Lee Jones' 2005 film "The Three Burials of Melquiades Estrada" can be described as a western will give an opportunity to explore some features of the genre, especially the geography of the Western, as well as study a few stories set in typical landscapes, focussing on the border between the United States and Mexico. That major locus in northern as well as mid-American imagination and culture is also the setting of a number of westerns and especially of John Ford's Rio Grande (1950), the source of our title as well as a fascinating inter-text to Tommy Lee Jones' work. A post mortem western, The Three Burials of Melquiades …
From alternative representations to prospective visions. The administrative subdivisions in Palermo (Italy)
2016
Alternative representations of the city are not only a useful analysis tool, but they also provide elements of a conceived new version of lived space that can contribute to ameliorate the spatial justice of the city. This is even truer for intra-local spaces that are the reference scale for many public participation policies, grass-root projects and activists. In this paper, we present the case of Palermo where the administrative subdivisions of the urban space have been imposed – because of legislation about administrative decentralisation – on the historical and perceived ones. Alternative mapping shows intra-local spaces as places of identity definition and civic engagement. In our paper…

Multi-Destination Trips and Tourism Statistics: Empirical Evidences in Sicily
2012
Abstract The knowledge of the actual magnitude and main features of tourism flows in a given destination is an essential prerequisite for the evaluation of tourism impacts and externalities. Indeed, many pleasure trips are often characterized by the visit to more than a single destination. Although the topic is well-documented in literature, the empirical results are limited to a few pioneering studies. The lack may be attributable to the failure of tourism organizations to collect data on multi-destination trip behaviour. This can be seen, for example, in the system of European statistics on tourism (according to the Council Directive 95/57 EC), where information on the average number of v…
Komunikacja transgraniczna straży pożarnej na polsko-czeskim pograniczu
2017
W pierwszej części artykułu autorka zwraca uwagę na specyficzne cechy komunikacji na pograniczu i podkreśla, że mamy tu do czynienia z dwiema wspólnotami komunikacyjnymi, odmiennymi pod względem kulturowym, narodowym i społecznym, które dążą do uzyskania porozumienia w akcie komunikacji. W akcie komunikacji transgranicznej wyróżniamy dwie sytuacje komunikacyjne: a) nagłego reagowania i b) improwizację akcji nagłego reagowania w celach dydaktycznych, w których barierami komunikacyjnymi są m.in.: nieznajomość języka i przeszkody dźwiękowe (hałas, praca maszyn itp.). Właściwe współdziałanie, czyli planowanie akcji gaśniczej i jej przeprowadzanie, wymaga pokonania barier w akcie komunikacji. Au…
An inhabited bridge between city and countryside
2015
With its propagation beyond the ancient walls in the countryside, the contemporary urban pattern of Piacenza flakes off, is frayed, making feeble the limit between rus and urbs; the continuous and porous old town gives way to the sprawl. In this project, the main idea is that, through moderate and small signs, defined by thematic pavilions (which are the general goal to achieve according to the Summer School), the effects can affect the urban scale, in a much wider field than the real area of intervention. So in this case the pavilion itself is thought as a bridge on the threshold between city and countryside. Moreover, the soil design, starting from the edges of the city, allows to fix the…
