Direito Internacional em matéria de água doce: conteúdo, formas e efetividade

Este trabalho objetiva analisar diversos aspectos do Direito Internacional Público em matéria de recursos hídricos de água doce superficiais e subterrâneos. Geração de energia, abastecimento, pesca, navegação, lazer, agricultura e indústria, são múltiplos os usos que os seres humanos fazem da água doce, mas antes disso a água é essencial para manutenção de todo e qualquer tipo de vida na Terra. São complexas e passíveis de várias análises as relações entre os Estados e as relações que se concretizam no interior dos Estados com objetivo de utilizar, controlar e preservar as fontes de água doce, a que se pretende fazer é uma análise jurídica, inserida no contexto político de expansão do capitalismo liberal. Pretende-se identificar e analisar normas jurídicas produzidas no âmbito internacional multilateral, considerando a sua forma, conteúdo e possíveis efeitos: na resolução de conflitos entre os Estados pelo controle e utilização da água doce, no estabelecimento de parâmetros para solução da crise ambiental e na superação dos problemas de acesso à água. Na primeira parte do trabalho, são identificadas as normas de Direito Internacional Público atinentes à matéria, descrevendo-se, primeiramente, a evolução histórica do Direito Internacional Fluvial até os estudos da doutrina de Direito Internacional e a Convenção de Nova York de 1997. O capítulo segundo objetiva apresentar o tema da água doce no contexto de surgimento do Direito Internacional do Meio Ambiente, de realização de conferências e criação de fóruns internacionais para a questão da água e do desenvolvimento de um direito humano à água. O capítulo terceiro propõe-se a ingressar na incipiente questão da regulamentação dos usos das águas subterrâneas, analisando os trabalhos da Comissão de Direito Internacional da Organização das Nações Unidas que culminaram com a adoção de uma Resolução sobre o Direito dos Aquíferos Transfronteiriços por parte da Assembleia Geral daquela organização. A segunda parte do trabalho objetiva analisar a aplicação das regras e princípios ensaiados nos textos de Direito Internacional aos casos concretos, confrontando-as com as soluções propostas em casos paradigmáticos de conflitos pela água, como o caso Gabcikovo-Nagymaros e o caso das Papeleras, envolvendo Argentina e Uruguai, ambos julgados pela Corte Internacional de Justiça. Na segunda parte do trabalho, também é analisado o caso do aquífero Guarani, um sistema de aquíferos interligados que se estende sob os subsolos de Argentina, Brasil, Paraguai e Uruguai, que em agosto de 2010 foi objeto de um tratado internacional assinado no âmbito do Mercosul. Por fim, a pesquisa objetiva desenvolver ideias e explicações para a existência (ou não) e a efetividade (ou a falta dela) das normas de Direito Internacional sobre recursos hídricos, considerando o conceito de soberania estatal que ora é o bode expiatório para a falta de assinaturas nos tratados ou de votos em declarações, ora é o próprio fundamento para a adoção de compromissos por parte dos Estados. Conclui-se tentando responder as seguintes questões: Existe Direito Internacional da água doce? São as normas de Direito Internacional efetivas? Para que servem essas normas de Direito Internacional, além da afirmação de sua própria existência como metas a serem atingidas?

Tomorrow's cities - a framework for building resilience

Urbanisation is the great driving force of the twenty-first century. Cities are associated with both productivity and creativity, and the benefits offered by closely connected and high density living and working contribute to sustainability. At the same time, cities need extensive infrastructure – like water, power, sanitation and transportation systems – to operate effectively. Cities therefore comprise multiple components, forming both static and dynamic systems that are interconnected directly and indirectly on a number of levels, all forming the backdrop for the interaction of people and processes. Bringing together large numbers of people and complex products in rich interactions can lead to vulnerability from hazards, threats and even trends, whether natural hazards, epidemics, political upheaval, demographic changes, economic instability and/or mechanical failures; The key to countering vulnerability is the identification of critical systems and clear understanding of their interactions and dependencies. Critical systems can be assessed methodically to determine the implications of their failure and their interconnectivities with other systems to identify options. The overriding need is to support resilience – defined here as the degree to which a system or systems can continue to function effectively in a changing environment. Cities need to recognise the significance of devising adaptation strategies and processes to address a multitude of uncertainties relating to climate, economy, growth and demography. In this paper we put forward a framework to support cities in understanding the hazards, threats and trends that can make them vulnerable to unexpected changes and unpredictable shocks. The framework draws on an asset model of the city, in which components that contribute to resilience include social capital, economic assets, manufactured assets, and governance. The paper reviews the field, and draws together an overarching framework intended to help cities plan a robust trajectory towards increased resilience through flexibility, resourcefulness and responsiveness. It presents some brief case studies demonstrating the applicability of the proposed framework to a wide variety of circumstances.

小湾电站坝基岩体卸荷工程地质力学研究

Dam is the key main works in the construction of water power. The success or failure of the construction of the dam mainly depends on the stability of the dam foundation. The double curvature arch dam-XiaoWan Dam is the highest one among the dams with the same type in the world, and the water thrust acted on it reaches ton, so the rock bearing capacity of dam foundation becomes more important. Because of the high and steep valley-side slope, the large scale of excavation and the complex body type of excavation, it is prominent that the problem of stress release of the rock mass in dam foundation. More great attentions should be paid for the stability and the degraded of rock properties of rock mass induced by the stress release. In this paper, the phenomena of stress release of rock mass in XiaoWan Dam foundation and its mechanisms were analyzed based on the collection of data, the detailed field engineering investigations, measurement of the rock mass and the 2D numerical calculations. The rock mass under the foundation is weak-weathered to intact, the quality of which is good. After excavation of the foundation, the rock mass near the slope surface occurred extend, stretch and stick-slip along original textures till the new fracture surface formed. Then platy structure of the rock mass takes on. The rock mass in the dam foundation occur resilience due to stress release towards free faces with the characteristics of time effect and localized deformation. In-situ measurements show that the rock mass near the surface are degraded. The stress release induced by excavation is a process of the interaction between engineering structures and geologic body. The stress release of rock mass in dam foundation is related to the changed degree of geometrical conditions. The rock near excavation surface failed nearly under uniaxial stresses. The bending-breaking mechanism of plate girder can interpret the failure model of the rock mass with platy structure in dam foundation slope. In essence, the stress release is the change of stress field including the change of directions and magnitudes of stress induced by excavation, which can induce the comedown of the safety margin. In this paper, the inducing conditions of stress release were calculated by numerical analyses. Moreover, from the point of view that the change of stress field, the coefficient of K, i.e. the variable load coefficient was proposed. Then the law of the change of it is interpreted. The distributional characteristics of fracture zone were expressed by the coefficient. The stress release of hard rock has the characteristic of localization. The measuring technique of sound wave can not reflect the small cracks in this kind of rock mass due to stress release. So, the spectral analysis method was proposed. At the same time, the application foreground in engineering of the Stockwell Time-Frequency- Spectrum method was discussed with a view to the limitation of it.

Ontario Paper Company Limited

On February 29, 1912 The Ontario Paper Company Limited was incorporated under the leadership of Col. Robert R. McCormick. Four months later construction began in Thorold, Ontario as this location was best for the abundance of power and water and water transportation. The first machine was started at the mill on September 5, 1913. The mill was one of the most advanced of its era, using electricity instead of water power. The mill was also the first of its kind as it combined pulp and paper making instead of separating the two operations.

Electrical Development Company of Ontario certificate of stock ownership, ca. 1910.

The Electrical Development Company of Ontario was created in 1903. It was one of three private power companies that had water power leases with the Niagara Parks Commission, but was the only one that was financed with Canadian capital. The company built the Toronto Power Generating Station at Niagara Falls beginning in 1906, and the power house was completed in 1913. During the construction, there was much debate about whether the utility should remain privately operated or become a public utility. In 1920, the company became part of the public utility.

La vulnérabilité face aux risques environnementaux à Kigali (Rwanda) : enjeux et facteurs

L’objectif de ce mémoire est de faire un état des lieux des connaissances produites sur les risques environnementaux et la vulnérabilité et appliquer ces connaissances à la ville de Kigali (Rwanda). Après avoir présenté différentes approches, nous avons retenu le cadre d’analyse qui s’inscrit dans l’approche de J.C. Thouret et R.D’Ercole (1996). Cette approche est articulée autour de trois dimensions : enjeux, facteurs de la vulnérabilité et réponses sociales. A travers l’application des éléments pertinents de ces trois dimensions dans le cas de la ville de Kigali, réalisée grâce à une analyse qualitative, centrée sur l’analyse des documents et des entrevues semi-dirigées, voici les principaux résultats que nous avons obtenus: l’analyse des enjeux a révélé que la ville de Kigali est confrontée à plusieurs dommages, parmi lesquels, on peut mentionner les pertes des vies humaines, la démolition des maisons, la contamination des rivières, la prolifération des maladies et la perturbation des besoins de base ( eau potable, électricité, transport) dues aux risques. Cette situation s’explique par la combinaison de plusieurs facteurs dont le relief collinaire, le sol granitique, les pluies violentes, le caractère centrifuge du réseau hydrographique, le sous-dimensionnement des ouvrages d’évacuation et le réseau d’assainissement insuffisant. D’autres facteurs amplifient la vulnérabilité dont l’explosion démographique consécutive à une urbanisation spontanée et inconsciente en zones inondables, l’ensablement des lits des rivières, le vide juridique, les politiques fragmentaires et le dysfonctionnement des acteurs impliqués dans la gestion des risques. Cette situation aurait probablement été améliorée si les réponses sociales étaient efficaces. Or, d’un côté, la faible perception de risque chez les résidants affectés par les risques accélère davantage la vulnérabilité et de l’autre côté, l’intervention significative des CIB n’est pas accompagnée d’actions complémentaires des institutions publiques et des agences internationales.

Present-day vegetation and the Holocene and recent development of Egelsee-Moor, Salzburg province, Austria

This paper describes the present-day vegetation, stratigraphy and developmental history of the mire of Egelsee-Moor (Salzburg, Austria; 45°45′N, 13°8.5′E, 700 m a.s.l., 15 ha in area) since the early Late Glacial on the basis of 4 transects with 14 trial borings across the peatland. We present a vegetation map of the mire, a longitudinal section through the peat body based on six cores showing the peat types, overview macrofossil diagrams of six cores showing the local mire development and two pollen diagrams covering the Late Glacial and Holocene. The chronology of the diagrams depends on biostratigraphic dating for the Late Glacial and early Holocene and radiocarbon dating for the remaining Holocene. The northern part of the mire originated through terrestrialisation of nutrient-rich, mostly inundated fen and the southern part through paludification of wet soils. The very small lake of today was a reservoir until recently for providing water-power for timber rafting (‘Holztrift’). The mire vegetation today is a complex of forested parts (mainly planted Pinus sylvestris and Thuja occidentalis, but also spontaneous Picea abies, Betula pubescens and Frangula alnus), reed-lands (Phragmites) and litter meadows (Molinietum, Schoenetum, etc.). The central part has hummock-hollow complexes with regionally rare species of transitional mires (Drosera anglica, D. intermedia, Lycopodiella inundata, Scorpidium scorpioides, Sphagnum platyphyllum, S. subnitens). The results indicate that some of the mid-Holocene sediments may have been removed by the timber-rafting practices, and that water extraction from the hydrological catchment since 1967 has resulted in a partial shift of transitional mire to ombrotrophic bog. The latter potentially endangers the regionally rare species and was used as an argument to stop further water extraction.
