Sustainable Development challenges will increasingly concentrate in cities as the urbanization in Europe and the rest of the world continues and governments must implement policies to ensure benefits of urban growths are shared sustainably. When more people move into the cities, the intimate contact with nature is lost since nature has not always been a priority in the history of urban planning. A biophilic approach is considered in this study, where the concept of inclusion of nature is perceived essential for the human life and previous empirical evidence supports the theory of presence of nature being substantial to human wellbeing. Because of the population density, Paris is an interesting example of the development of a megacity in a post-Kyoto context. The development project for the Paris urban area, called Le Grand Paris, intends to develop Paris on several levels. The aim with this study is to examine driving forces for nature as a part of an urban setting that can contribute to the development of intelligent sustainable urban planning for the future. Using qualitative methods to gather empirical data and a discourse analytical framework, this study intends to increase the understanding of perspectives, incentives and discords in the perceptions of urban green space and Sustainable Development. The problem statement is: How is urban green space carried out in the perspectives of cultural, economical and ecological values of citizens and planning documents in the context of Le Grand Paris project? The results establish that that need of increasing vegetation in the city of Paris is pressing in order to enhance quality of life and increase effects of ecological services. The continuing urbanization of Paris will intensify the need of social-ecological interactions, which require approaches through processes of democracy and participation in order to contribute to intra- and intergenerational socio-ecological justice for a sustainable Paris.

The traditional lands of the Southern Paiute people are bounded by more than 600 miles of Piapaxa (Colorado River) from the Kaiparowits Plateau in the north to Blythe, California in the south. According to traditional beliefs, Southern Paiute people were created in this traditional land and, through this creation, the Creator gave Paiute people a special supernatural responsibility to protect and manage this land including its water and natural resources. Puaxantu Tuvip (sacred land) is the term that refers to traditional ethnic territory. Within these lands no place was more special than Piapaxa 'uipi (Big River Canyon) where the Colorado River cuts through the Grand Canyon.

This report concludes the first four years (1992 -1995) of Southern Paiute involvement in the Glen Canyon Environmental Studies (GCES), a program initiated by the Bureau of Reclamation (BOR) in 1982. Southern Paiutes have conducted ethnographic research and participated in the Congressionally mandated Environmental Impact Study (EIS) of Glen Canyon Dam water release policies on natural and human-made resources found in the Colorado River Corridor. These ethnographic studies have taken place in what is called the Colorado River Corridor which extends 255 miles down stream from Glen Canyon Dam to the end of the free flowing river at Separation Canyon within the Grand Canyon National Park. They have concentrated on investigating the impacts of the Dam's water releases to Southern Paiute cultural resources. Since the Final EIS was published in March 1995, emphasis has been placed on what is called the Adaptive Management Program of the GCES and attention has shifted to monitoring the water release impacts.

The historically introduced House Rock Valley bison herd has, in recent years, migrated from the eastern Arizona Strip onto the Kaibab Plateau within Grand Canyon National Park. Bison are considered a nonnative species to the southern Colorado Plateau, and the animals adversely impact sensitive ecosystems prompting National Park Service wildlife managers to pursue their removal. Archaeofaunal evidence of bison in the Grand Canyon and neighboring regions, however, raises concern that bison may in fact be native. Assessing the evidence within a zooarchaeological interpretive framework is critical since mere presence/absence lists of bison remains do not address the potentially complex cultural processes involved in the formation of archaeofaunal assemblages. Inter-assemblage comparisons illustrate a decline in relative abundance and skeletal completeness correlated to distance from traditionally understood historical bison distribution. If bison were present in the Southwest, as the evidence suggests, they likely entered the region only occasionally as small, dispersed herds.

In Recreating Nature: Ecocritical Readings of Yosemite and Grand Canyon, I examine the intersections of culture and nature in two prominent national parks, and I consider the implications of nature-tourism in the environmental discourse of the U.S. Covering a period from 1848 to the present, my project aims to correct an oversight in scholarship about the park system, in which legacies of colonialism and imperialism--when addressed at all--tend to be historicized and framed as the age-old sins of a presumably reformed national politic. Instead, I examine both historical and present-day developments, emphasizing the profound cultural influence of the places we designate as natural. I define ecocriticism as an inherently interdisciplinary endeavor attuned to the interconnectedness of things. My methodology is to engage texts, images and other expressions of the national parks in a process of extended close reading and comparative analysis. While observing the particular contexts of each case, I attempt to locate these texts amidst the broadest but most essential critical terrain: they each negotiate a dialogical relationship between culture and nature. By setting the stage for examining the human and its relation to the non-human other, the parks have become key sites for displaying the recreation of nature. After my introduction I discuss John Muir's My First Summer in the Sierra, focusing on an episode where Muir risks his life for a view from Yosemite Falls. I also consider Muir's failure to empathize with Native Americans he encountered. In my next chapter I analyze John Wesley Powell's Exploration by focusing on his attempt to assert authority over a region by prioritizing the scientific tone in his writing. Next I synthesize historical and contemporary sources, discussing Mary Colter's Grand Canyon architecture alongside the Grand Canyon Skywalk, a glass-bottom walkway on the Hualapai Indian reservation. In the following chapter I compare the acrophobia-inducing photographs of George Fiske and Emery Kolb. Finally, I discuss transit real and imagined in Grand Canyon and Yosemite, considering the utopian potential of national parks. I close by revisiting questions about our changing environmental discourse and about the future of ecocriticism.

The superior growth of Grand fir (Abies grandis) compared to Douglas-fir (Pseudostuga menziesii) on suitable coastal sites has previously been recognized on the basis of qualitative observations with little empirical evidence. For example, D.E. McMullan (1977, pers. comm.) reported 18% higher volume for a grand fir tree of the same height and age as a 108-year old Douglas-fir plus tree (No. 622) This study was undertaken by Bernardy (1988) to examine possible differences in the growth of grand fir and Douglas-fir growing in a mixed 40-year-old plantation of unknown origin. Trends in height, diameter and annual volume increment between the two species over time were examined. Expected growth performance (i.e. volume and form) of each species was inferred from trends identified at time of sampling.

Municipal wastewater effluent (MWWE) has the potential for aquatic degradation, as it is the largest, per volume, anthropogenic discharge in Canada and other areas in the world. With an increasing population in many areas, such as Southern Ontario, there is concern that infrastructure of wastewater treatment facilities will not be able to maintain adequate treatment and prevent further degradation of the environment. The Grand River watershed, in Southern Ontario, is predicted to have its population increase to 1.2 million people by 2031 (from 780,000 people in 2001). Although wastewater treatment has improved, concern remains for receiving environments due to inadequate treatment (i.e. Kitchener) and minimal dilution (i.e. Guelph). This research was conducted to understand current impacts of MWWE in the Grand River watershed on fish communities to support future management and protection. Study sites upstream and downstream were chosen for their proximity to the Guelph, Kitchener, and Waterloo MWWE outfalls, similarity in habitat, and wadeability. Habitat analysis indicated that there were no large physical differences among sites. Fish communities were collected in a standardized method with a backpack electroshocker at each site (six randomly selected 10 m by 10 m sub-sites for 5 min). Greenside Darter (Etheostoma blennioides) and Rainbow Darter (E. caeruleum), the most abundant species, were also analyzed for stable isotope signatures (δ13C and δ15N) at each site. Downstream of the Guelph outfall there were no changes in mean total catch per unit effort (CPUE) or mean total mass. Changes to diversity, resilience, and tolerance in the fish community were attributed to a decreased abundance of Greenside Darter and increased abundance of Rainbow Darter. Downstream of the Kitchener discharge, there was a trend towards decreasing mean total CPUE, especially for darter species, and an increase in mean total mass due to a community shift to larger species including Catostomids and Centrarchids. The changes in abundance of Rainbow Darter, Catostomids, and Centrarchids among reference and Kitchener MWWE exposed sites explained the pattern in resilience, tolerance, and diet classifications. Lower diversity downstream of all three MWWE outfalls can be attributed to the increase in Rainbow Darter abundance. Stable isotope signatures (δ13C and δ15N) of Greenside Darter did not change downstream of the Guelph and Waterloo discharges, but signatures of Rainbow Darter increased immediately below the two outfalls. This shift may be due to the Rainbow Darter being able to take advantage of a change in the environment (i.e. food availability), resulting in its increased abundance and changes in isotopic signature. Directly downstream of the Kitchener outfall both darter species had an increase in δ13C and a large decrease in δ15N, likely due to high nutrient inputs from the outfall. The Kitchener wastewater discharge is also associated with a decrease in abundance of fish and a shift in community structure. MWWEs are currently affecting the aquatic environment, including fish communities in the Grand River watershed. Future investments in infrastructure and watershed management should be made to mitigate degradation of water quality in this watershed.

La thèse tend à démontrer que le législateur français n'a pas encore, du moins dans la sphère extra-patrimoniale, pris la mesure de l'évolution démographique, sociologique et psychologique de ce que certains chercheurs hors du champ juridique dénomment la grand-parentalité. Les aïeux ont naturellement un rôle à jouer dans le droit de la filiation, parce qu'ils sont les plus anciens représentants d'une lignée : ils devraient être une référence mentale et culturelle. Mais ce rôle n'est pas ou n'est plus conçu comme un ensemble cohérent par le droit, parce que les règles de la filiation elles-mêmes ont explosé, laissant place à une recherche biologique sans ambition trans-générationnelle, ou - en matière d'adoption - à un système rétracté sur la cellule adoptant-adopté et non ouvert sur la famille dans son ensemble. Il en va de même pour le droit du nom, qui décalque le droit de la filiation...
