Seventy-five years ago the provincial governments of Manitoba, Saskatchewan, and Alberta signed a series of Natural Resources Transfer Agreements (NRTAs) with the federal government. These agreements provided the answer to a contentious debate known as the 'Natural Resources Question'. Before the NRTAs, the three prairie provinces did not have control over their public domain lands and did not share equal constitutional status with the other Canadian provinces. In the early 1920s, Prime Minister King recognized the validity of the provincial arguments for constitutional equality and no longer wanted the federal government to be responsible for the administration of provincial natural resources. By this time, the policy ambitions which had previously justified the retention of the natural resources had been fulfilled. Thus, the constitutional rights arguments presented by the prairie provinces found a receptive audience when the control of the lands and resources were no longer a federal priority.

Fire history and fire-climate relationships of upper elevation forests of the southwestern United States are imperative for informing management decisions in the face of increased crown fire occurrence and climate change. I used dendroecological techniques to reconstruct fires and stand-replacing fire patch size in the Madrean Sky Islands and Mogollon Plateau. Reconstructed patch size (1685-1904) was compared with contemporary patch size (1996-2004). Reconstructed fires at three sites had standreplacing patches totaling > 500 ha. No historical stand-replacing fire patches were evident in the mixed conifer/aspen forests of the Sky Islands. Maximum stand-replacing fire patch size of modern fires (1129 ha) was greater than that reconstructed from aspen (286 ha) and spruce-fir (521 ha). Undated spruce-fir patches may be evidence of larger (>2000ha) stand-replacing fire patches. To provide climatological context for fire history I used correlation and regionalization analyses to document spatial and temporal variability in climate regions, and El-Niño Southern Oscillation (ENSO), the Pacific Decadal Oscillation (PDO) and the Atlantic Multi-decadal Oscillation (AMO) teleconnections using 273 tree-ring chronologies (1732 - 1979). Four regions were determined by common variability in annual ring width. The component score time series replicate spatial variability in 20th century droughts (e.g., 1950’s) and pluvials (e.g., 1910’s). Two regions were significantly correlated with instrumental SOI and AMO, and three with PDO. Subregions within the southwestern U.S. varied geographically between the instrumental (1900-1979) and the pre-instrumental periods (1732-1899). Mapped correlations between ENSO, PDO and AMO, and tree-ring indices illustrate detailed sub-regional variability in the teleconnections. I analyzed climate teleconnections, and fire-climate relationships of historical upper elevation fires from 16 sites in 8 mountain ranges. I tested for links between Palmer Drought Severity Index and tree-ring reconstructed ENSO, PDO and AMO phases (1905-1978 and 1700-1904). Upper elevation fires (115 fires, 84 fire years, 1623- 1904) were compared with climate indices. ENSO, PDO, and AMO affected regional PDSI, but AMO and PDO teleconnections changed between periods. Fire occurrence was significantly related to inter-annual variability in PDSI, precipitation, ENSO, and phase combinations of ENSO and PDO, but not AMO (1700-1904). Reduced upper elevation fire (1785-1840) was coincident with a cool AMO phase.

This dissertation argues that the Ontario-Manitoba Boundary Dispute (1870-1889) and its aftermath limited the ability of the Ojibway of northwestern Ontario to maintain and develop their interests in the lands and resources to which they were entitled by the terms of Treaty #3, signed in 1873. In particular, their rights to the mineral and timber resources on their reserves were threatened. Furthermore, once the Boundary Dispute was resolved in favour of Ontario, their reserve lands were found to be in the province, which therefore gained the right to confirm the reserves. Continuing disputes between the province and the Dominion resulting from this retroactive decision delayed this confirmation until 1915. Once the reserves were confirmed, however, the nature of the Indian interest in them prior to 1915 was questioned by the province. In this and other ways, the fiduciary responsibilities of the federal government toward the Ojibway were encroached upon by the province of Ontario. The governments and individuals involved in the lawsuits generated by the Boundary Dispute overlooked the fate of an increasingly marginalized and politically inconsequential group in the pursuit of their own agendas and interests. The courts squeezed the concepts of Aboriginal title to the land and its resources into narrow nineteenth century perceptions that still limit the rights of First Nations peoples. Placing these cases, in particular the "Indian Titles" case, R. v. St. Catharines Milling & Lumber Co., and its 'corollary', Ontario Mining Company v. Seybold et al., into their historical context contributes to understanding the complex problems still faced by the Ojibway of Treaty #3. The dissertation concludes with an exploration of the continuing attempts made by the Ojibway to assert their rights in light of these events.

Der volle Inhalt der QuelleAnnotation:
Over the past decade (2000-), the management of vestibular schwannomas has been in a state of flux. An increasing availability of magnetic resonance imaging has allowed clinicians to monitor tumour progression and increasingly, it has become recognised that once diagnosed, a significant proportion of lesions do not continue to grow. As a result, a number of neurotological centres have advocated conservative management as appropriate for small-medium sized tumours. Birmingham has been one of these centres, and this thesis presents data gathered over the past fifteen years that reflects this change in management, drawing upon the Birmingham Vestibular Schwannoma Database maintained by the author. The thesis addresses issues pertinent to conservative management: growth rates among observed tumours, risk factors for growth, the evolution of hearing while under observation and proposes a radiological surveillance protocol. More broadly, the thesis examines other themes important in the management of patients with vestibular schwannomas: the role of functional surgery and the possibility of rehabilitation in single-sided deafness. A number of chapters from the thesis have been published in peer-reviewed journals and are presented here in updated or amended form.

Kuwait is an arid small country with a severe climate, but an interesting and diverse biological heritage. Historically Kuwait was the home for 28 mammalian, over 300 bird, and 40 reptilian species. Expanding human population and technology are increasingly altering Kuwait's natural habitat. Currently, 8 mammalian species are locally eradicated from Kuwait, but available elsewhere in the Arabian Peninsula. On the endangered list is 4 mammals, 5 birds. The status of most reptiles is unknown. A comprehensive overview of Kuwait's historic and contemporary wildlife is described. Major wildlife habitat types are identified and mapped. A conservation strategy addressing the wildlife and their habitats in Kuwait is suggested. The key to a successful strategy is habitat restoration and protection combined with legal protection of the wildlife. In addition, a program for re-introducing locally eradicated species to their historic range in Kuwait is suggested.

This thesis is an account of the challenges people in Tyefu Location, Peddie District, and specifically in Gwabeni village, face in their attempts to manage their common pool natural resources. Taking my analytical cue from the literature which deals with the institutional dimensions of resource management in common property systems, I look at the impact of both outside influences and local dynamics on resource managing institutions at village level. I show how particular historical circumstances, including state interventions, led to the enclosure of Tyefu Location, and to the rapid increase in the population that had to be accommodated here. This placed enormous pressure on the natural resources of the area, and contributed to the emasculation of the local institutions responsible for overseeing resource management. The residents of the location adopted whatever strategies they could to ameliorate the depletion of natural resources in their villages. One 'traditional' strategy they have sought to emulate is to move their imizi (homesteads) away from areas where local resources has been exhausted. Given the finite area of land available to them, this strategy was only ever likely to be successful in the short-term. I analyse social, economic and institutional factors at village level that appear to act as disincentives to collective resource management activities. These factors include the social structure of the imizi and the socio-economic heterogeneity that exists between imizi in Gwabeni village. The varying degrees of household economic marginality that follow from this, together with the differential ownership of livestock and other possessions that decrease people's reliance on locally available natural resources, mean that the transaction costs that people would incur by contributing to collective resource management activities, differ widely. A primary cause of people's failure to engage in resource management at village level stems from the dispersion of the members of their imizi. This factor robs the village of decision makers and undermines the capacity of those left behind to make and implement resource management decisions. It results in the various members of imizi in the village having different orientations that dissipate the energy needed for collective action. It also fuels existing struggles, and creates new ones, over the meanings and uses of the term 'community'. I conclude by arguing that, in Tyefu Location, the management of natural resources is extremely difficult to co-ordinate, because such management is highly contested, undermined by differentiation among resource users, and subject to the attentions of weak village institutions that do not share a clear set of resource management objectives.KMBT_363

Der volle Inhalt der QuelleAnnotation:
Recent advances in conflict studies have led to relatively robust conclusions that inequality fuels conflict when it overlaps with salient group identities. Central to quantitative studies supporting this relationship is a stipulated causal chain where objective group – or horizontal – inequalities are translated into grievances, which in turn form a mobilization resource. All these studies are however limited by their use of objective measures of inequality, which leaves them unable to directly test the assumed grievance mechanism. In four papers I argue that objective asymmetries are not enough to trigger conflict. For people to take action on horizontal inequalities, they will have to be aware of them and consider them unjust. In the first paper, Perceptions, Horizontal Inequalities and Civil Conflict, I use data from the World Values Survey to show that perceived rather than objective economic inequality between sub-national regional groups is associated with increased risk of civil war. In the second paper, Injustice is in the eye of the beholder: Perceived Horizontal Inequalities and Communal Conflict in Africa, I analyse 20 countries covered by the Afrobarometer Surveys. I conclude that combined objective and perceived economic ethnic inequality, political ethnic inequality, and particularly perceived political ethnic inequality, increase the risk of between-group conflict. In the third paper, Expectations, Grievances and Civil Unrest in Emerging Petrostates. Empirical Evidence from Tanzania, I present evidence suggesting that those who feel that their region has been treated unfairly by the government are most prone to support and participate in civil unrest. I base my conclusions primarily on survey data collected in 2015. In a final article, From Silence to Storm. Investigating Mechanisms Linking Structural Inequality and Natural Resources to Mobilization in Southern Tanzania, I rely on 35 semi-structured interviews to argue that natural gas mismanagement triggered group grievances, which in turn fuelled civil unrest.

Der volle Inhalt der QuelleAnnotation:
A renewed discussion about inequality and economic divergence between countries has re-introduced the debate about the role played by natural resources, geography and the institutions of settler capitalism as promoters of growth and development in the long-term. Countries like Canada, Argentina, Australia and New Zealand, among others, expanded their frontiers of settlement, created important infrastructural transformations, received millions of immigrants and capital and became the most important producers of natural resources for exports during the first era of globalization (c. 1850-1914). Comparative studies that study these countries’ development have particularly praised the democratic distribution of land in small lots, like in the United States and Canada, which created a class of successful farmers. With the help of Geographic Information system (GIS), this dissertation revisits the political economy of Western Canada settlement by using a historical economic geography approach. Previous investigations on Western Canada settlement used decennial census records to estimate where settlers established themselves. This method is problematic as the expansion of the frontier of settlement happened on a very dynamic period where settlers moved frequently from one region to another. The use of annual postal records, instead, provides a more complete understanding of the region. As postal facilities opened where immigrants had already established themselves, the location of post offices gives a more nuanced understanding of the evolution of the frontier of settlement. This study reconstructed the historical postal and railroad networks that revealed an uneven pattern of settlement with more details. Similarly, by analyzing updated homesteads entries and cancellations data during the period, this dissertation found that farmers’ failures were more frequent than the classical literature assumed, particularly after the 1890s, a period scholars regarded as one of more stable settlement. The production of space and the formation of the institutions in Western Canada from the 1850s to 1914 shows the dynamic of capitalist expansion and natural resources exploitation in a new territory. The location of post offices helps to understand in a granular form the uneven development of regions and the emergence of small communities that later became nodes of an important railroad network.

Thesis (PhD)--Stellenbosch University, 2015.ENGLISH ABSTRACT: This study explores hunting in the Lower Tchiri Valley as an arena in which African and white hunting interests as well as conservation policies precipitated insurgence and accommodation, collaboration and conflict. Precolonial Magololo hunters, having supplanted Mang’anja hunting as a result of the superiority of their hunting technology by 1861, found themselves in competition with white sport hunters over game animals. Unequal power relations between the Magololo hunters and the white hunters, who formed part of the colonial administration in Nyasaland from the 1890s, saw the introduction of game laws that led to wild animals and their sanctuaries becoming contested terrains. Colonial officials and some whites enjoyed privileges in hunting game whose declining populations were blamed on Africans in general and the Magololo in particular. Some Africans and certain whites devised hunting strategies that brought them into conflict with the colonial state. In the Lower Tchiri Valley, the tsetse-game controversy led to game being slaughtered on an unprecedented scale in the Elephant Marsh region. The Game Ordinance of 1926, intended to prevent such wanton destruction, was protested by settlers, planters, white hunters and even missionaries who claimed to represent the interests of the “natives”. The colonial state and the Colonial Office in London quelled the protests, proclaiming Lengwe and Tangadzi as game reserves. As the state was consolidating the game preservation economy and establishing the game reserves from the 1930s to 1960, opposition continued. The implementation of international conservation trends locally, particularly after 1945, served to entrench illicit hunting and the position among some white settlers that game should be exterminated as it was incompatible with agricultural “progress.” The Nyasaland Game Department increased its efforts to ensure that killing game for crop protection was confined to Game Guards, one of whom, an African named Biton Balandow, became a local “hero”. Despite this, by 1960 game populations in the Lower Tchiri Valley reserves were still declining. Together with oral testimonies collected in the communities neighbouring the reserves (or former hunting grounds), the fresh perspectives rendered in this thesis derived from a systematic use of reports, original research papers, colonial administrative correspondence and autobiographical works of big-game hunters-turned preservationists. Specific material for the Lower Tchiri Valley hunting economies from these primary sources allowed this thesis to transcend the often generalised analyses necessitated by macrooverviews in Malawian historiography, and offer a more nuanced study of local contestations between state and subject, between competing individuals, between groups, races and generations and, enduringly, between human and animal.
AFRIKAANSE OPSOMMING: Hierdie studie ondersoek jagaktiwiteite in die Laer Tchiri-vallei van Malawi as ‘n gebied waar swart en wit jagtersbelange, asook bewaringsbeleid, teenstand en aanvaarding, sowel as samewerking en konflik ontketen het. Pre-koloniale Magololo-jagters, wat Mang’anja-jagters teen 1861 as gevolg van hulle superieure jagtegnologie verdring het, het toe met wit sportjagters om wild begin kompeteer. Ongelyke magsverhoudinge tussen die Magololo- en wit jagters, wat sedert die 1890’s deel uitgemaak het van die koloniale administrasie in Nyassaland, het tot die daarstelling van wildwetgewing gelei. Op sý beurt het die wildwetgewing en wildbewaringsgebiede betwiste terreine geword. Koloniale amptenare en sekere blankes het jagvoorregte geniet waarvoor die daarmee gepaardgaande blaam vir dalende wildpopulasies op swartes in die algemeen en die Magololo in die besonder geplaas is. Sommige swartes en wittes het jagstrategieë ontwikkel wat hulle in konflik met die koloniale staat gebring het. In die Laer Tchiri-vallei het die tseste-wild-twispunt daartoe gelei dat wild op ‘n ongekende skaal in die Olifant-moerasgebied uitgeroei is. Wit setlaars, boere en jagters, selfs sendelinge wat daarop aanspraak gemaak het dat hulle die belange van die “naturelle” verteenwoordig het, het egter beswaar gemaak teen die Wild Ordonnansie van 1926, wat veronderstel was om sulke ongebreidelde vernietiging te voorkom. Die koloniale staat en die Colonial Office in Londen het die besware onderdruk deur Lengwe en Tangadzi as wildreservate te proklameer. Van die 1930’s tot 1960, toe die staat besig was om die wildbewaringsekonomie te konsolideer en wildreservate te vestig, het teenstand daarteen voortgeduur. Die plaaslike implementering van internasionale bewaringstendense, veral ná 1945, het egter daartoe bygedra om onwettige jagaktiwiteite te verskans. Dit het ook die standpuntinname van sommige wit setlaars, dat wild uitgeroei moes word omdat dit onversoenbaar met landbou “vooruitgang” was, versterk. Die Nyassaland Departement van Fauna het pogings verskerp om te verseker dat die doodmaak van wild, ter wille van oesbeskerming, tot wildbewaarders beperk bly. Een van hulle, ‘n swartman genaamd Biton Bandalow, het ‘n plaaslike “held” geword. Maar ten spyte van hierdie maatreëls was die wildpopulasies in die Laer Tchiri-vallei wildreservate teen 1960 steeds aan die afneem. Hierdie proefskrif bring nuwe insigte aangaande jagaktiwiteite en wildbewaring in die Laer Tchiri-vallei na vore. Die bronne daarvoor is mondelinge getuienis wat in die gemeenskappe aangrensend aan die wildreservate (of voormalige jaggebiede) versamel is. Daarby is verslae, oorspronklike argivale dokumente, koloniale administratiewe korrespondensie en outo-biografiese werke van grootwildjagters wat wildbewaarders geword het, ook sistematies nagevors. Deur middel van spesifieke inligting aangaande die Laer Tchiri-vallei jagtersekonomie wat uit die primêre bronne verkry is, bring hierdie proefskrif nuwe perspektiewe na vore wat in teenstelling staan tot die dikwels geykte analises wat in makro-historiese oorsigte van Malawiese historiografie voorkom. Derhalwe is die proefskrif ‘n meer genuanseerde studie oor plaaslike wedywerings tussen staat en onderdaan, tussen wedywerende indiwidue, tussen groepe, rasse en generasies en op ‘n blywende basis ook tussen mens en dier.

National parks share the same challenge debating the significance of their cultural and natural resources. In the past, many parks decided to emphasize the value of natural resources over that of their human histories. Theodore Roosevelt National Park was an exception to that trend because of its connection to President Theodore Roosevelt. In the early years of the park?s existence, National Park Service management emphasized the value of its cultural resources. The preservation and interpretation of Theodore Roosevelt?s Maltese Cross Cabin and Elkhorn Ranch were two of the park?s top priorities. Around the 1980s, park officials increasingly placed emphasis on the park?s natural resources in an attempt to balance the significance of its natural and cultural resources. Through this attempt, Theodore Roosevelt National Park has embraced the concept that human and natural history cannot and should not be separated.Theodore Roosevelt National Park.

Gorongosa: a history of an African landscape, 1921-2014, focuses on changes in the Gorongosa ecosystem, in central Mozambique, southeastern Africa. Environmental changes result from natural, non-human causes and from the activities of humans. I describe four socioecological events: African and Portuguese interactions, Gorongosa National Park, the effects of Mozambique’s civil war, and the Park's restoration in the aftermath of the civil war. Prior to European partition of Africa in 1884-85, Mozambique did not exist as clearly a demarcated territory as it is now. Today, the sense of Mozambicanhood bears traces of Portuguese colonial era experience. The demarcation of Mozambique’s boundaries and the reshaping of the colony until 1975 was a painful process that both the Africans and Portuguese colonialists endured; these physical and social separations from the rest of southern Africa represented the first human-induced changes in southern Africa. The endeavors to reshape Mozambique did not end with political boundaries. Painful processes, including the reshaping of Gorongosa National Park in the Gorongosa ecosystem, continued after border demarcations. Countless Mozambican and Portuguese lives were lost in the long trajectory within the colony as the Africans and the Europeans all developed a sense of unity in diversity while reshaping their attitude of and about Mozambique. After independence in 1975, internal transformations and wars continued reshaping Mozambique and Mozambicans, as different nationalists sought to maintain their colonial experience. These dynamics marked the environmental history of the Mozambican and Portuguese peoples and are often reflected in the prevalence of high sympathy, which the two peoples share toward one another. Gorongosa: a history of an African landscape, 1921-2014, critically celebrates these collective achievements.

Der volle Inhalt der QuelleAnnotation:
This thesis consists of three stand-alone papers. It examines the economic and political effects of natural resources in Africa. In the first paper, we investigate the effect of mining activity on subnational economic development by using satellite data on night lights as a measure of economic development. We find that mineral production and discovery improves local economy. However, we do not observe (strong) general equilibrium effect beyond the confines of a district. In the second paper, we test the link between natural resources and multiethnic power sharing coalitions in Africa. We find that resource discoveries and rising commodity prices increase the probability of representation at the executive branches of government. Our finding supports the idea that resource discoveries and rising commodity prices provide rulers with more revenues to expand the state cabinet sizes; hence they build broader multi-ethnic coalitions. In the third paper, we investigate the association between natural resources and intra-state local armed conflict in Africa. We find that natural resource discoveries do not trigger armed conflict in Africa at the local level. Consistent with the finding in the first paper (positive economic effect) and second paper (positive political effect), resource discovery appears to reduce the likelihood of armed conflict by increasing the opportunity cost of joining armed rebellion.

We reconstructed historical fire regimes of montane forest-grassland ecotones in the ~40,000 ha Valles Caldera National Preserve, New Mexico. We used a targeted approach to sample ancient fire-scarred trees along the ecotone, and compared variations in historical fire occurrence within and among valles in the grassland-forest. The resulting tree-ring record extends from 1240-2008 C.E., comprised of 2,443 fire scars from 330 trees representing 238 fire years during the period of analysis, 1601-1902 C.E. Our results confirm pre-1900 historical occurrence of high-frequency, low-severity surface fires over multiple centuries in the ecotone. Mean fire intervals for all fires were 5.5-22.5 years (~6-123 ha) at individual sites, 2.7-10 years (~67-4955 ha) in individual valles, and 1.6 years (~10 386 ha) across the landscape. Synchronous fires burned extensively and occurred at ~10 year intervals during years with significantly low PDSI. Results will be useful in planning forest/grassland restoration actions and reinstituting fire regimes.

Brousil, Matthew R. „Compounding Fire Disturbance History Encourages Coast Redwood (Sequoia sempervirens) Regeneration and Community Dominance“. DigitalCommons@CalPoly, 2016. https://digitalcommons.calpoly.edu/theses/1688.
Der volle Inhalt der QuelleAnnotation:
Disturbance is fundamental to forest ecosystem function and overall health, but climate change is likely to increase both disturbance frequency and intensity in the future. Forests subject to increasingly frequent and intense disturbances are more likely to experience compounding disturbance effects. Compounding disturbances may exert unpredicted, non-additive stresses on ecosystems, leading to novel conditions that may exceed the capacity for local species to survive and regenerate. I further hypothesize that compounding disturbances could create conditions misaligned with species’ adaptations by altering physical and chemical growing conditions in forest soils, affecting forest composition, structure, and, subsequently, function for many years following disturbance. A better understanding of these remnant effects will be essential to managing and conserving coast redwood forests, which are projected to see increased frequency of fire under future climate scenarios. My objectives in this study were to quantify the effects of time-since-fire and single vs. compounding disturbances on coast redwood forest structure, composition, and regeneration dynamics and to evaluate the effects of abiotic soil qualities on post-fire regeneration. I mapped and sampled coast redwood forests burned in 1985, both 1985 and 1999, 2008, and 2013; modeled regeneration as a function of burn history, understory light, and post-fire nutrient levels; and tested redwood seed regeneration in post-fire soils in a greenhouse experiment. Forest structure, composition, and regeneration following compounding disturbance were most similar to the homogenous, redwood-dominated forest of the recent 2013 burn. There were no unique effects of compounding disturbance on soil nutrient levels, although variations in nutrient levels generally followed patterns seen in previous studies. Soil nitrate was positively associated with coast redwood regeneration levels, showing that soil nutrients may be influential in regeneration processes following disturbance. Time since burn and single burn histories were negatively associated with regeneration levels in the field, and there were no differences in seed germination in the greenhouse between soils from different fire histories. Increases in coast redwood forest dominance accompanied declines in bay laurel and tanoak presence, indicating a shift in post-fire forest structure and composition resulting from compounding disturbance. These results illustrate a complex relationship between regeneration dynamics, post-fire soil quality, and disturbance histories. Forest homogenization from compounding disturbances may have negative implications for ecosystem services and overall function if compounding disturbances are more frequent as predicted under future climate conditions.

The Pacific Crest Trail has become increasingly popular since Clinton Clarke first envisioned such a trail in the 1930’s. By comparing the original motives and experience of the trail to the realities of the trail today, the trail’s fluid narrative becomes apparent. While this narrative is ever changing, over the course of the trail’s history one theme has remained constant – a notably problematic relationship with wilderness rooted in an exaltation of the sublime and post-frontier ideals. This thesis focuses on how the Pacific Crest Trail’s development over the past eighty years has created an experience that, on the surface, is notably different from Clarke’s original vision for the trail, but is still influenced by a perception of wilderness born from a romanticization of nature and a pursuit to preserve the western frontier. Chapter one, The Historic Trail, investigates Clarke’s manners and motives behind promoting the trail. Chapter two, The Popular Trail, examines the visual culture surrounding the trail, from nineteenth century landscape painting to the trail’s presence in social media today. Chapter three, The Trail Community, focuses on the growth of a strong community of hikers, and what this means for the future of the trail.

Velvet mesquite (Prosopis velutina Woot.) is a common tree in semi-arid, southwestern U.S. savanna ecosystems. While there are studies that examine some of the physiological and ecological aspects of this tree (response to fire, net ecosystem exchange, encroachment into grasslands, yearly growth through dendrometer bands, among others), the wood anatomical features of a growth ring, suitability for dendrochronological research, life history, and above-ground biomass through time are knowledge gaps that can be filled. The purpose of this study was to examine these gaps in order to better understand the role of velvet mesquite in these ecosystems. Wood anatomical analysis showed that velvet mesquite has a semi-ring porous structure and termination of the growth ring is indicated by a small band of parenchyma. Visual crossdating of velvet mesquite was successful but a complex growth habit, with both eccentric and lobate growth, combined with ecological pressures hampered statistical validation of the chronology. Seasonal climate-growth analysis of dated rings showed a strong positive correlation to previous year September and October precipitation and a strong positive partial correlation to previous year September and August mean temperature. Life history through growth curve analysis showed no age related growth trend (either s-shaped or log normal) indicating the maximum age of velvet mesquite stems sampled (130 years old) can become much older with many releases and few suppressions. Above-ground biomass of these trees are low compared to higher elevation forest biomass, but similar to other savanna ecosystems of the southwest. The use of velvet mesquite in dendrochronological research would greatly benefit from a complete analysis of wood anatomy, and addition of more samples from various locations to verify dates and begin building more reliable chronologies for this species across its range. These additions would allow for a greater understanding of stand and tree level responses through suppressions and releases, and understand the biomass accumulated above-ground through time.

On March 22, 1958 David Brower's film Wilderness Alps of Stehekin premiered to an audience of conservationists in Seattle, Washington. Almost two years in the making, the thirty-one minute film advocated the preservation of nature in Washington's North Cascades through the creation of a national park. Over the next decade, Wilderness Alps of Stehekin became the most influential publicity tool in the struggle to preserve the North Cascades. Because of the region's geographic isolation, the film was the first time many people throughout the nation were exposed to the scenic grandeur of the area. Images of craggy peaks and colorful alpine meadows resonated deeply with many Americans and persuaded them to join in the campaign. It was the voice of these citizens that led Congress to pass the North Cascades Act of 1968, which placed 674,000 acres of the North Cascades under the jurisdiction of the National Park Service.
In this thesis I tell the creation story of North Cascades National Park from a conservationist perspective and trace the influence of Wilderness Alps of Stehekin within this context. Although the film was never shown in movie theaters and never aired on national television, many thousands viewed it from its premiere to the signing of the North Cascades Act. The film first introduced the idea of a North Cascades National Park, and it was important in convincing conservationists to unite around a national park solution. Ultimately, Wilderness Alps of Stehekin changed the approach activists took in the North Cascades and helped to preserve a wild and scenic nature experience for future generations through the protection of old-growth forests and alpine meadows.

The American West is a land of great diversity and stark contrast. It is also a landscape marked by rapid change as a result of such forces as globalization, population growth, and heightened interest in natural resources (either for recreation or extraction). This dissertation investigates these changes to the region through a repeat photography analysis. Between 1982 and 1984, Thomas and Geraldine Vale traveled along U.S. Highway 89 from Glacier National Park, Montana to Nogales, Arizona. Their subsequent work, Western Images, Western Landscapes: Travels Along U.S. 89 (University of Arizona Press, 1989), contained fifty-three photographs from this journey, representing a cross section of the West from border to border. Nearly every facet of the region was represented, from the remote prairie landscapes of Montana to the bustling Phoenix downtown, and from the largest open pit mine in the world to seldom visited corners of Yellowstone National Park. Between March 2009 and August 2010, I retraced the steps taken by the Vales and successfully rephotographed all of the locations contained within their book. The observed continuity or change is examined thematically in order to address the landscapes and cultures of the West in greater detail. Specifically, chapters within this dissertation visually and textually describe changes that have occurred along national borders, within Native American reservations, throughout the rural landscapes and national parks of the region, within the many resource extraction industries, and within towns and cities of every size. Significant findings, which are well depicted in the photographic pairings, include heightened national security along the borders, problems of overuse in many parks and protected areas, the transition of traditional small towns into communities increasingly dependent upon tourism for survival, and both beautification and revitalization efforts taking place in the urban cores of Phoenix and Salt Lake City. By painting a vivid picture of recent Western geography, this research provides for greater ability for residents and scholars of the region to understand the forces at work within their communities and surroundings.

Ecological conservation and restoration in the anthropocene must struggle with overlapping drivers of biodiversity and cultural loss; ruptures of the ecological environment mirror ruptures of human relationships with nature. And yet technology cannot remove humans from nature; technological and infrastructural reconfigurations of nature create new vulnerabilities and risks for humans and ecosystems alike. How can conservation and restoration science productively grapple with complex infrastructure systems and decision-making processes as biophysical and social drivers of ecosystem change?
Using dam removals in the USA and in the Mid Columbia River region of the Pacific Northwest, this dissertation develops a conceptual framework for Social, Environmental, and Technological Systems (SETS), and applies it at three spatial and temporal scales to the practice of dam removal as a river restoration strategy. Drawing upon existing data sets, as well as biophysical, document, survey, and interview data this dissertation addresses how dam removals have functioned in the context of the social histories of river restoration programs, examines how these restoration programs must continue to renegotiate the human relationships with nature through the infrastructure systems that enable certain forms of existence while precluding others.
Of particular interest is how restoration programs have increasingly functioned to deliver novel infrastructure solutions, while ignoring longer-term changes in ecological structure and function due to infrastructure development; in other words, the infrastructural work of restored ecosystems, and the infrastructural blind spots of restoration programs.
How restoration planning considers, or does not consider, infrastructural blind spots, is indicative of not only the biophysical drivers of threatened and endangered species loss, but also the political dynamics of decision making at large, and the power-knowledge relationships constituting legitimate and relevant knowledge in the decision making space.
In the Pacific Northwest, there appears to be a tipping point of social convention in centering treaty rights and obligations vis-a-vis ongoing processes of colonization and institutionalized scientific expertise. Ecological restoration will only be successful if it addresses both engineered infrastructures and social justice.

The movement to conserve natural resources in the United States began as a response to the perceived inefficiency which governed resource allocation. The subsequent environmental movement served to expand the definition of conservation to include not only the efficient use of resources, but also the preservation of land in its natural state. In Indiana, this supposed deficiency in conservation led some environmentalists to establish the Indiana Nature Preserves System which locates remnants of the Indiana wilderness and protects them from development. The Indiana Nature Preserves System is symbolic of the Land Ethic proposed by the early ecologist Aldo Leopold, who believed that man was but one component of the "land community." To alter all natural areas, Leopold and Indiana preservationists argued, was both an assault on ecological stability and on the right of nature to exist for its own sake.Department of History

The purpose of this capstone project is to tell a place-based story about an often forgotten part of campus: the Wash. Beginning as a likely Tongvan campsite, the Wash, after donation to Pomona College as “Blanchard Park” underwent a series of land-use changes. Originally, a designated green space, its present-day composition includes athletic fields, the organic farm and the historic remnant oak grove. Throughout time the value of the Wash changed with its differing caretakers and inhabitants. To bring attention to this evolving landscape and to inform more sustainable and equitable land use in the future, our project aims to acknowledge past narratives about this place, take stock of its present ecological significance and recommend best practices going forward. We accomplished this by putting together a history of the Wash using indigenous knowledge, archival information, biological surveys and GIS.

The role of natural resources in African conflicts has been subject to extensive scholarly analysis. However, much of this analysis has taken a narrow economic reductionist bias. As such, it is imperative that the dominant assumptions and accepted concepts and theories about the role of natural resources in African conflicts be re-examined. The aim of this thesis is to offer a revaluation of the role of coltan during the Democratic Republic of Congo’s (DRC) Second War (1998-2003) through a critical engagement with the resource wars literature. The purpose is to offer a re-reading of the role of coltan in the DRC Second War and the broader regional and global economic context in which this conflict took place. It rejects the commonly cited assumption that the presence of coltan in the DRC means it is an initiator of conflict. Rather, this thesis argues that the central role of coltan in the DRC Second War was as an aggravator of conflict in that its exploitation was used by different parties to fund their military and political ambitions. This thesis also argues that the DRC’s weak state structures and pivotal role within the Great Lakes region, as well as the international trade of coltan and the nature of the DRC coltan mining industry are all key factors in understanding coltan exploitation in the country’s Eastern Region during the Second War.

The general objective has been to empirically analyze how Hotelling’s rule has predicted the crude oil price development over the last 100 years and if the rule can work as a framework to predict future resource prices. Hotelling’s rule has been perceived as both outdated and relevant, during the last decades. A general conclusion from previous research is that resource price-developments are more complex than Hotelling assumed. The analysis has been conducted through tests of variables like interest rates, time spans and extraction costs. The assumption of exponentially increasing resource prices has also been tested. The results obtained show no general support for the Hotelling-rule’s ability to predict future prices. Our results suggest that Hotelling’s rule predicts price paths best when a short time-span is considered. The lack of predictability is due to high volatility in resource prices, something Hotelling’s rule does not account for.Det övergripande syftet med denna studie har varit att empiriskt analysera hur väl Hotellings-regel har förutspått utvecklingen av oljepriset under de senaste hundra åren och om regeln fungerar som ett bra ramverk för att kunna förutspå framtida resurspriser. Hotellings-regel har uppfattats som både föråldrad samt relevant under de senaste årtiondena. En generell slutsats från tidigare forskning är dock att utvecklingen av icke-förnybara resursers priser är mer komplex än vad Hotelling antog. Analysen har utförts genom tester av olika variabler som räntor, tidsperioder och utvinningskostnader. Antagandet om exponentiellt ökande resurspriser har också testats. De erhållna resultaten ger inget generellt stöd för Hotelling regeln som ett bra ramverk till att förutspå framtida resurspriser. Resultaten tyder dock på att Hotellings-regel förutspår framtida priser bäst när en kortare tidsperiod antas. Modellens avsaknad av förutsägbarhet är sannolikt på grund av volatilitet i resurspriser, något som Hotellings-regel inte tar fullt hänsyn till.

Der volle Inhalt der QuelleAnnotation:
Temperate forests are an important carbon sink, yet there is uncertainty regarding land-use history effects on biomass accumulation and carbon storage potential in secondary forests. Understanding long-term biomass dynamics is important for managing forests as carbon sinks and for co-benefits such as watershed protection and biodiversity. However there are many unanswered questions regarding these dynamics in northeastern U.S. forests: How have secondary forests of the U.S. Northeast recovered post nineteenth century agricultural abandonment? How has the region's extensive land-use history influenced long-term structural development and aboveground carbon storage? To answer these questions, we employed a longitudinal study based on twelve years of empirical data (2001-2013) from the Marsh-Billings-Rockefeller (MBR) National Historical Park in Woodstock, VT. MBR Park was the first parcel of land to actively be reforested in the eastern U.S., and as such, its diverse forest mosaic reflects a history of alternate reforestation approaches and varied successional trajectories indicative of secondary forest recovery occurring across the broader northeastern forest landscape. We also used 150 years of documentary data from park management records. This research evaluates the effects of reforestation approaches (planting vs. natural regeneration), management regimes (long-term low-to-intermediate harvest intensities at varied harvest frequencies), and stand development pathways on biomass outcomes. We generated biometrics representative of stand structural complexity, including the H' structural diversity index, and aboveground biomass (live trees, snags, and downed coarse woody debris pools) estimates. Multivariate analyses evaluated the predictive strength of reforestation approach, management history, and site characteristics relative to aboveground carbon pools and stand structural complexity.
Classification and Regression Tree (CART) analysis ranked reforestation approach (plantation or natural regeneration) as the strongest predictor of long-term mean total aboveground carbon storage, while harvest frequency, and stand age were selected as secondary variables. CART ranked forest percent conifer (a metric closely associated with reforestation approach) as the strongest predictor of H' index, while harvest intensity, and harvest frequency were selected as secondary variables. Increases in harvest intensity can significantly reduce aboveground carbon storage. Our results suggest that a variety of long-term recovery pathways converge on high levels of aboveground carbon storage, including both conifer plantations and naturally regenerated hardwood stands, but choice of silvicultural management approach can dramatically alter those trajectories. Importantly, total aboveground biomass (i.e., carbon) co-varied with H' (r2 = 0.25), and thus, our dataset showed a positive relationship between forest carbon storage and structural complexity, supporting the concept of multifunctional forestry emphasizing late-successional habitats.

Der volle Inhalt der QuelleAnnotation:
This dissertation traces the history of cattle grazing at Saguaro NP, Organ Pipe Cactus NM and Fort Bowie NHS in southern Arizona. This collection of studies examines the factors affecting that use, the ranchers who made their living from the landscape, and the federal land managers responsible for sustaining the natural and cultural resources.
A dominant industry on arid public lands since the Civil War, grazing was altered by a variety of influences: environmental and human-derived. Ranching communities developed from homesteading settlements. Success was determined by climate, topography, and natural resources; social and cultural pressures; economic events and political legislation; and later federal regulations and decisions.
The first agency to oversee grazing, USFS was under constant pressure to maximize short-term human benefits. The NPS Organic Act of 1916 mandated conservation of natural resources "by such means as will leave them unimpaired for future generations" and yet approved cattle grazing, an extractive use, under USFS management. Park managers were frustrated by grazing practices not under their control. Parks were at a cultural and social disadvantage. Residents and politicians often expressed displeasure at park reservations; communities feared that parks would interfere with local industries.
Park employees supervised visitors and developed recreation infrastructure; they came with little experience to manage livestock. Lack of funding for research, limited manpower, and political and administrative interference allowed cattle grazing to continue unregulated for decades altering vegetation and enhancing erosion. In the 1960s, changing values from the environmental movement, the waning power of the livestock industry, and the rise of activist scientists impelled NPS to act. Without monitoring data, NPS turned to legal opinions to terminate grazing.
Now grazing is regulated and carefully monitored. NPS is mandated to incorporate research results into management decisions. Older grazing permits are being retired, but land acquisitions for park additions add new management challenges. Purchasing permits offers a new but financially limited opportunity to protect sensitive lands. Grazing has ended at all three parks, yet ecological changes and historic structures remain. As cultural and administrative legacies, those remnants offer opportunities to interpret a significant regional tradition and an untold controversy.

Due to escalating carbon-based emissions, anthropogenic climate change is wreaking havoc on the natural and built environment as higher near-surface temperatures cause arctic ice-melt, rising sea levels and unpredictable turbulent weather patterns. The effects are especially devastating to inhabitants living in the water-worlds of developing countries where environmental pressure only exacerbates their vulnerability to oppressive economic policies. As climatic and economic pressures escalate, threats to local resources, living space, safety and security are all reaching a tipping point. Climate refugees may survive, but they will fall victim to displacement, economic insecurity, and socio-cultural destruction. With the current economic system in peril, it is now a matter of urgency that the global community determine ways to modify their behaviour in order to minimize the impact of climate change. This interdisciplinary comparative analysis contributes to the dialogue by turning to environmental history for similar scenarios with contrasting outcomes. It isolates two North Atlantic water-worlds and their inhabitants at an historical juncture when the combination of climatic and economic pressures threatened their survival. During the sixteenth and seventeenth centuries, the Hebrideans in the Scottish Insular Gàidhealtachd and the Wabanaki in Ketakamigwa were both responding to the harsh conditions of the ‘Little Ice Age.’ While modifying their resource management, settlement patterns, and subsistence behaviours to accommodate climate change, they were simultaneously targeted by foreign opportunists whose practices and perceptions inevitably induced oppressive economic pressure. This critical period in their history serves as the centre of a pendulum that swings back to deglaciation and then forward again to the eighteenth century to examine the relationship between climate change and human behaviour in the North Atlantic. It will be demonstrated that both favourable and deteriorating climate conditions determine resource availability, but how humans manage those resources during feast or famine can determine their collective vulnerability to predators when the climate changes. It is argued that, historically, climate has determined levels of human development and survival on either side of the North Atlantic, regardless of sustainable practices. However, when cultural groups were under extreme environmental and economic pressure, there were additional factors that determined their fate. First, the condition of their native environment and prospect for continuing to inhabit it was partially determined by the level of sustainable practices. And, secondly, the way in which they perceived and treated one another partially determined their endurance. If they avoided internal stratification and self-protectionism by prioritising the needs of the group over that of the individual, they minimised fragmentation, avoided displacement, and maintained their social and culture cohesion.

The aim of this thesis is to find the historical differences of nationalization in a peripheral and in a central country. I will look at and compare the development and the processes of nationalization of the petroleum and hydropower industries in Mexico and Norway and how these differed from a world system perspective. The question of nationalization of resources and the countries' respective history in this field are oftentimes invoked in discourses in both countries. The latest examples thereof were the debate about the need to join the Agency for the Cooperation of Energy Regulators (ACER), a regulator that all EU members are part of without most even being aware that their country is participating in it, but that in the case of Norway's decision to join it in spring 2018 lead to massive campaigns involving trade unions and environmental organizations, and which the Norwegian Labor party have a large internal debate on whether joining an organization that regulated energy trade would have negative consequences for Norway1. In Mexico, the theme of oil is one of the favorite themes of newly elected President Andrés Manuel Lopez Obrador. He promised that he would stop any privatization efforts of either electricity or petrol sector should he win. Given that the question seems so important to each country, one has to wonder why the outcome is so different.

Der volle Inhalt der QuelleAnnotation:
Until the 1990s, salmon had been extinct from the Umatilla River for over 70 years. The struggle to bring salmon back to this river is a compelling story that exemplifies some of the new relationships in Columbia River Basin salmon management.
The Umatilla River and the disappearance of its salmon was a local issue. Irrigation interests had used the river so thoroughly it ceased to flow during the late summer and fall months-precisely when salmon needed it for migration. The Confederated Tribes of the Umatilla Indian Reservation saw decided that they would change that: they would figure out a way to put both salmon and water back into the river.
This thesis examines this process. First, it contextualizes the Umatilla River within the Columbia River Basin and Columbia Basin salmon management, and shows how a local salmon issue became a regional salmon issue. It then discusses the triangle of relationships that Indians, salmon, and hatcheries have come to form. Chapter III discusses the formation of the unique Umatilla Fish Restoration Program, which reintroduced fish into the river, and was paid for by the Bonneville Power Administration (BPA), as per the Northwest Power Act. Key elements within BPA's Fish and Wildlife Division resisted complying with the directives of the Northwest Power Planning Council to pay for the Program, setting the Program back years. I argue that this comes from two clashing ways of seeing the River: "cost-benefit analysis" versus "least cost."
Chapter IV looks at the new partnerships formed in the Umatilla River Basin by the Tribes and irrigation districts in order to encourage the U.S. Bureau of Reclamation to construct a water delivery system that would satisfy irrigators while allowing most of the Umatilla to flow freely.
The last Chapter suggests that these new and somewhat ironic partnerships between federal and state governments, private irrigators and landowners, nongovernmental organizations, and Indian tribes are key to restoring ecosystems in the Columbia River Basin. It further argues that without tribal nations playing an active role and exerting their treaty rights, restoring rivers like the Umatilla is impossible.

Der volle Inhalt der QuelleAnnotation:
It is hypothesized that individuals make reproductive decisions based on current assessments of their physiological condition and environmental conditions. For female lesser scaup (Aythya affinis), breeding occurs after an energetically costly spring migration. Increasing fat reserves (i.e., ‘body condition’) prior to breeding allows a female to produce a larger clutch of eggs, but time spent gaining body condition is costly in terms of time allowed to raise ducklings before freezing conditions in the fall. In Chapter 2 I explored rate of pre-breeding body condition gain in female lesser scaup, and how that rate influenced clutch size. Spring phenology, measured by proxy as water temperature, and water depth strongly influenced the rate at which females increased body condition. Early springs with low water levels led to greater rates of body condition gain in female scaup. The higher the rate of body condition gain, the larger the clutch of eggs females produced. Body condition is also an important determinant of breeding in female ducks; females in poor body condition are more likely to forego breeding. I explored how body condition, wetland conditions, and prior experience influence a female’s decision to breed in Chapter 3. Body condition was a strong determinant of when a female bred, with females in good body condition breeding earlier than females in poorer body condition. Habitat conditions were also important, with drought reducing the proportion of breeding lesser scaup females. In Chapter 4 I examined survival costs of reproduction in female scaup. Nesting exposes females to increased predation risk (a concurrent survival cost), and reduced post-breeding body condition may reduce female survival the subsequent non-breeding season (a serial, or ‘downstream’, survival cost). Female survival during breeding and non-breeding seasons was most correlated with breeding season water level on the study site, but in opposite directions. Breeding season survival increased with increasing water levels, while non-breeding season survival declined. High water levels on the study site increased the availability of presumably high-security nesting habitat, and also increased female reproductive effort. The former increased breeding season survival, while the latter reduced non-breeding season survival.

L’épuisement des énergies fossiles est un thème d’actualité dont les prémices datent, selon l’opinion courante, des années 1970 et du premier choc pétrolier. En réalité, c’est une préoccupation plus ancienne, intimement liée à l’ère industrielle. Dans la deuxième partie du XIXème siècle, les économistes se sont penchés sur la question de l'épuisement des minerais, ‘objet non identifié’ jusqu'alors et nécessitant la mise sur pied de nouveaux outils d'analyse (effet-rebond chez Jevons, rente minière chez Marshall-Einaudi notamment). Avec le progrès des techniques et l'apparition de nouvelles énergies (pétrole, hydro-électricité), leurs craintes de déclin industriel se sont progressivement dissipées dans les années 1910 et 1920. Mais ces évolutions tenant à l’histoire des faits ne sont pas les seules à considérer. Des facteurs internes à la discipline économique, comme l'émergence du marginalisme dans les années 1870 et de la théorie de l'épargne et du capital dans les années 1890, ont aussi changé le regard des économistes sur la question de l'épuisement des ressources. Pourquoi ? Comment ? Quels enseignements peut-on en tirer pour les défis environnementaux d'aujourd'hui ? Voilà les questions qui sont traitées dans ce travail de thèseFossil fuels exhaustion is a current topic. It is often said that its first presages appeared in the 1970s with the first oil shock. Actually, this exhaustion fear is much older than that, it started with the Industrial Revolution and kept going since then. In the second part of the 19th century, some economists focused their attention on the mineral resources depletion, which was at the time an ‘unknown item’ that necessitated the creation of new concepts and new analytical tools to deal with (for example Jevons’ rebound-effect, Marshall-Einaudi’s mining rent). In the 1910s and 1920s, thanks to technical progress and the development of new energies (oil, hydro-electricity), their fears about industrial decline progressively dissipated. Yet, these factual evolutions are not the only ones to consider. Internal factors, inside economic science (marginalism in the 1870s, capital theory in the 1890s), also shaped economists’ viewpoint on resources exhaustion. Why? How? What lessons can we get from this period for our current environmental challenges? These are the questions that are studied in this thesis

This thesis offers a political geography of unconventional energy development through a study of a particular fossil fuel resource called oil shale. Having long occupied a critical place in the politics and economy of certain states, most notably in Estonia, oil shale is now widely known as an ‘unconventional’ resource that is yet to become technically possible, commercially viable and socially acceptable to exploit. Following the movement through which oil shale becomes both unconventional and conventional, the thesis traces the resource through a series of geo-scientific, economic and political interventions. This study is based on analysis of technical literature and policy documents along with ethnographic fieldwork, interviews, and site visits conducted in Estonia, Colorado, Utah, Jordan, London and Brussels. Drawing together relational accounts of natural resources in political ecology and economic geography with insights from Science and Technology Studies, this project both contributes to critical research on the carbon economy and to recent debates on the concepts of materiality, anticipation, and marketization in social sciences. The thesis proposes a relational conceptualization of resource materiality, situating oil shale in multiple and conflicting forms which derive from geographically disparate practices in both resource assessment and technological development. The future of oil shale exploitation is not pre-determined by the process of global resource decline, nor is it precluded by international demands to move towards lower-carbon futures. Rather, it is determined through the conjunction of different future-oriented economic and political calculations that are entangled with resource materials and associated technological systems. Developing a non-essentialist account of markets as socio-technically distributed arrangements, the thesis argues that these rival calculations influence the design of market rules for both energy and emissions trading. The thesis concludes that what counts as ‘unconventional’ is not given, but continues to be both created and contested at the same time as it is ‘conventionalized’.

Esta dissertação tem como objetivo investigar em que medida os esforços para a recuperação ambiental do Lago Guaíba em Porto Alegre e na sua região metropolitana decorreram de uma participação mais intensa da população local na definição das prioridades para os investimentos públicos, e de que forma tem-se dado esta participação, identificando os agentes sociais envolvidos e seus limites de atuação. Não é possível abordar este problema sem considerar uma envoltória mais ampla, que inclua as relações da sociedade local com as praias do Guaíba e o aproveitamento paisagístico de sua orla urbana, dando conta de sua historicidade. O problema é estudado a partir de diferentes perspectivas, que estão interligadas. Em primeiro plano, são destacados os processos de exercício da cidadania e de formação de uma consciência social, no que se refere à mobilização popular para o atendimento de demandas básicas de qualidade de vida, como o saneamento básico, mas também o acesso a um meio ambiente não degradado. A consolidação destes processos, de uma forma mais efetiva, é fortemente associada à capacidade dos agentes sociais nele envolvidos de obter a intervenção do Estado, por meio da aplicação de políticas públicas especificamente voltadas ao atendimento destes objetivos.This work aims to investigate the local society role in the efforts that had been performed towards the environmental recovery of the Lake Guaíba, in the city of Porto Alegre and its metropolitan area, addressing public investments prioritization processes, and identifying the social agents involved with the subject and their limits of actuation. Local society relations with lake’s urban shoreline and beaches, in a historical perspective are also addressed. The subject is studied from different perspectives, which are interconnected. In the first plane, the processes of citizenship exercise and social conscience formation, leading to people’s mobilization towards the extension of essential services, like basic sanitation, but also requesting environmental protection and recovery measures. The consolidation of these processes strongly depends on the involved social agent’s capability to obtain State’s intervention trough public policies specifically addressed to these objectives.

Trois agglomérations majeures caractérisent le système territorial bolivien en concentrant près de la moitié de la population et des emplois nationaux. Ce constat amène à s'interroger sur le rôle économique de cette tripolarisation territoriale face au succès économique de Potosi et Tarija, territoires riches en ressources naturelles. Dans ce travail, nous examinons l'actuelle tripolarisation par l'étude de l'histoire économique de l'émergence de ces trois pôles, puis en examinant les données économiques les plus récentes, de manière à expliquer les forces et les faiblesses de ce tripôle. Chacun des pôles se localise dans un contexte géographique original. La Paz où siège le gouvernement se situe dans la région montagneuse des hauts plateaux à l'Ouest. Santa Cruz, à environ 900 km de La Paz, se localise à l'Est, au centre des plaines amazoniennes. Cochabamba se situe entre les deux, dans les vallées intermédiaires du centre. Cette tripolarisation est relativement récente : la hiérarchie urbaine, longtemps dominée par une ville primatiale n'a donné une configuration tripolaire qu'au cours du dernier demi-siècle. La situation actuelle résulte en partie du cadre particulier de l'émergence du tripôle, liée aux territoires disposant des ressources naturelles ; l'analyse est conduite à partir d'indicateurs d'activité économique et du rôle international de ces territoires. L'approche économique, combinée avec des éléments géographiques, démographiques, historiques, politiques et de développement humain, permet de mettre à jour deux logiques distinctes, mais qui se complètent d'une manière originale : une forme de domination territoriale du tripôle La Paz - Cochabamba - Santa Cruz, à la fois permise et fragilisée par le rôle clé de l'exploitation des richesses naturelles de Potosi et Tarija
