澜沧江流域(云南段)水资源开发利用现状及趋势分析

澜沧江是一条国际河流,其中云南段自然资源丰富,水文、地理及气候特征独特。目前该流域水资源开发利用程度较低,仅有少量的灌溉面积,干流也仅建成了一个径流式水电站。作为我国西南地区的重要水电能源基地,流域的进一步开发将集中于水电、航运和农业灌溉。其开发方式具有立体开发、电力先行和国际合作开发等特点。     

Environmental conservation and the production of new territories: the example of French départements

Very important initiatives have been taken and policies have been adopted in the European Union to protect areas of great importance for threatened species and habitats. Protected areas differ broadly in terms of category, natural conditions and administrative organisation, from international initiative such as Biosphere Reserves, European ones with Natura 2000 network until the institution of national and regional protected areas. In France, the administrative subdivisions known as “départements” were created with the French Revolution in the end of the eighteenth century; in 1985 an original and autonomous procedure to establish special protected areas, called “Sensitive Natural Spaces” (SNS) was devolved to them. The scope of this paper is to present an overview of these devolved powers which enable French départements to create protected areas and to levy a departmental tax on sensitive natural spaces (DTSNS). We statistically studied some parameters by multivariate methods in order to explain the choices of this policy by the départements. The huge variations in the way these powers are implemented prove the development of new environmental territories.

Boundaries and transborder relations,or the hole in the prison wall: On the necessity of superfluous limits and boundaries

Boundaries can be seen as barriers or as places of contact. It has been suggested that we are “prisoners of borders”, of all kinds of borders (political, religious, social, cultural, linguistic etc.). While this statement appears to be somewhat exaggerated, it holds some truth. Boundaries are elements in spatial organization, and they influence daily life in many ways (not only for people living right along them). The paper addresses the question if we must call ourselves “prisoners” or if we simply have to live with all kinds of borders. Departing from theoretical observations, the paper discusses the various aspects boundaries assume in the European context before looking at a few concrete Swiss examples. They reveal that even regions at a certain distance of the state border will feel its effects (the case of Zurich airport), but the most important benefit can been drawn by people living in the border area itself (through price differences between the two countries, as exemplified by the Swiss-Italian border). There may be asymmetry on state borders, but this asymmetry can also swing around: the advantages often lie on both sides. The paper concludes by pointing to the persistence of the boundary concept. They are a necessity for the organization of space and society, but they are not absolute. There are always holes in these prison walls, and the examples where boundaries were impermeable are probably rare.     

‘Boundary’ in Ancient Persian Tradition of Statehood

It is universally accepted that the need for defining precise lines of separation and points of contacts between states is the byproduct of the emergence of nation-states and ‘world economy’ in the 19th century Europe. Nevertheless, it is hard to overlook the fact that these modern notions are rooted in periods prior to the emergence in Europe of nation-states. There are indications that ancient civilizations were familiar with the notion of ‘state’ in connection with the concepts of territory and boundary. Ancient texts reveal that this basic principle existed in ancient Persian literature in respect of matters of state, territory, and boundary. Similarly, the likelihood exists that these Persian notions could have influenced Roman civilization. It is widely believed that a combination of ancient Greco-Roman and Persian civilizations is a major contributor to what culturally constitutes ‘West’. Later in the Sassanid period the inter-linked notions of state, territory, and boundary developed substantially, coming quite close to their contemporary forms. On the other hand, considering that ‘justice’ was the corner stone of ancient Persian Political philosophy, the idea that ancient Persian spatial arrangement might have contributed to the evolution of the concept of democracy in the West may not be too difficult to contemplate.     

Itacolumite, flexible sandstone and flexible quartzite - a review

Flexible quartzitic rocks are found in various locations around the world and have been identified as both sandstones and quartzites. The term itacolumite was first used for a Brazilian quartzite thought to be a new type of rock in 1822. As analytical methods have improved flexibility has been shown to be due to irregular interlocking quartz grains surrounded by regular intergranular spaces. Platy minerals such as muscovite are sometimes present and probably add support to the structure, but are not necessary for flexibility. The underlying cause of the texture appears to be chemical dissolution of quartz at the grain boundary.     

Metamorphism of sedimentary rocks recognised by 19th century French naturalists: A case study from the Chavanon sequence marbles,Massif Central,France

The Chavanon metamorphic sequence in the Variscan French Massif Central contains marble lenses that have been exploited since at least the 18th century to produce lime. They provided an opportunity to some major pioneers among nineteenth century French geologists to understand how metamorphic rocks are formed. The intimate association between marbles and gneisses led them to propose that the initial pile of rocks was deposited as a single unit under water. They thoroughly described the attitude, folding and mineralogy of the marbles, making their works of great historical value. Originally written in French, their translation into English and the reproduction of original figures from the works they published will be very useful to the international community of geologists interested in the history of their science.     

Government regulation in the Australian popular music industry: The rhetoric of cultural protection, the reality of economic production

In the 1990s the artistic autonomy of the territorial subsidiaries of the major record companies increased. Local scale “cultural freedom” did not mitigate the role of national regulation, with the music industry remaining bound by regulation imposed by agencies representing nation-states. National-scale policy rhetoric highlighting the need for “cultural protection” focused attention away from an interest in the economics of popular music, a balance evident in policies of Australian federal governments. In seeking to increase the export potential of locally produced music, Australian governments have come to hold an important place in the political economy of contemporary Australian music.     

Government policies and international migration of skilled workers in Sub-Saharan Africa

Since a central concern of the geography of international migration is to consider how and why stocks and flows of migrants are variable from country to country, the study of skilled international migration must address policies of individual governments towards local and foreign skilled workers. These policies are most evident in immigration and emigration legislation, regulations and practice, but also, less directly but often of more fundamental significance, in policies in education, manpower planning and towards wages and salaries. In Sub-Saharan Africa there is a wide range of experience of recent skilled international migration, driven by direct and indirect policies pursued by individual governments since independence. At an intercontinental scale the deleterious effects of the global division of labour have not merely been passively accepted; within the continent new patterns of skilled-labour migration have been created by increasingly differentiated economic performance and political relationships. A case study of Kenya, a country of small current net immigration of skilled workers, is used to specify some of the processes that establish the relationships between immigration and emigration policies, and how these have been mediated by conditions for skilled workers. The concluding section of this paper sets the general experience and that of the Kenyan case study in the wider context of the role of the state as a factor in the geography of skilled international migration in the Third World.     

Variegated borderlands governance in Dehong Dai-Jingpo Autonomous Prefecture along the China-Myanmar border

International borders and associated borderlands—especially as viewed at the national and international scales, and via regional and global-scale maps—are generally thought of as being primarily governed by national governments. In reality, however, national borders and associated borderlands are complex and varied spaces, ones that are governed not only through national laws and regulations, but also an array of policies and localized practices, both formal and informal, conceived and implemented by government agencies and other non-government entities operating at various scales. This is especially the case for the borderlands we are focusing on. In this article we conceptually apply Agnew’s idea of the ‘territorial trap’, Ong’s notion of ‘graduated sovereignty’, Laine’s conceptualization of the ‘multiscalar production of borders’, Amilhat Szary and Giraut’s concept of ‘borderity’, and Brambilla’s understanding of ‘borderscapes’ to consider the multiscalar and multi-sited nature of borderlands governance along the China-Myanmar border in Dehong Dai-Jingpo Autonomous Prefecture, Yunnan Province, China. Focusing on the China side of the border, we emphasize how different scales of government agencies and non-government entities variously interact. Ultimately, these different actors create multiscalar borderscapes dependent on various situational factors, ones which are more complex than is typically acknowledged by national governments.

Satellite imagery and the spectacle of secret spaces

This paper documents and assesses emerging efforts to resist and subvert deep-seated and long-held governmental secrecy over geographical spaces of military/security activities and other sites deemed sensitive by the state. It explores tensions in new web-served mapping and high-resolution imagery of these sites, which view them though ‘pin holes’ of publicly available data. These ‘counter-mappings’ focus attention on the significance of sites that are either buried unnoticed in seamless global image coverage, or else censored on official mapping. Some reveal a tenaciously anti-hegemonic and oppositional discourse, others a more playful set of cultural practices, one that ridicules as much as directly resists. We situate these newly witnessed secret sites in contemporary visual culture, exploring the spectacular and Debordian possibilities of resistance that they offer, and evaluate the significance and ironies of these diverse imaging practices.     

Governing minorities and development in Xishuangbanna, China: Akha and Dai rubber farmers as entrepreneurs

In Xishuangbanna, southern Yunnan, Akha and Dai farmers, regarded in China as “backward”, passive recipients of state-led development, have been “getting rich” on rubber and expanding rubber cultivation into neighbouring Laos. State cash crop campaigns to raise minority farmers’ incomes inadvertently turned minority farmers into dynamic entrepreneurs. This paper builds on Vinay Gidwani’s use of development as a “regime of value” to raise social and economic value to analyze these unexpected results. Local state agents believe they are the agents of development, bringing modest social and economic improvements to minority farmers of obdurate backwardness. Minority farmers see themselves as improving their own incomes and “quality”, a term in China for social value, in an era when they are responsible for their own development. National development discourse encourages citizens to raise population quality by becoming entrepreneurial, a message heard by minority rubber farmers as well as urban elites. Through creative, post-Fordist production models and agile deployment of land, labour, and capital, minority farmers have achieved incomes that exceed those of workers on state rubber farms, large plantations whose Fordist production models are losing out in the uneven transition from a planned economy to a more capitalist market assemblage. Akha and Dai rubber farmers, the “backward” minorities on China’s periphery, have unexpectedly become the forerunners of flexible production arrangements that are prevailing in the arena opened up by China’s 2001 entry into the World Trade Organization.     

San Diego–Tijuana: Not quite a binational city or region

The cities of San Diego and Tijuana have faced each other across the international boundary for over 100 years. The question raised by this article is whether they comprise a binational city or region. After a brief comparison of their histories, economies and political systems, a review of some indications of cross border attitudes and a discussion of binational regionalism as it is impacted by continentalism, it is concluded that the relationship between these cities is driven by factors of economics not friendship or trust.

International students as urban agents: International education and urban transformation in Auckland,New Zealand

This paper discusses connections between the internationalisation of education, and in particular the growth in international students, and processes of urban transformation. The research is centred in Auckland, New Zealand, a city where the number of international students has grown rapidly over the last decade leading to significant impacts on the urban form and experience of the city’s CBD. This includes growth in educational services such as language schools and other private training establishments, new residential geographies characterised by low-cost and low-quality high-rise developments, and new ethnic economies of food, service and entertainment businesses that explicitly target international students. The paper draws on research with South Korean international students and a range of secondary materials to interrogate the connections between student mobilities and changing urban form. In doing so the paper contributes to emerging scholarship on student geographies and the role of students as urban agents through the inclusion of an international dimension that has largely been absent in the extant literature. The findings illustrate that while international students themselves clearly play a significant role in the transformation of urban spaces their influence cannot easily be separated from the contribution of a range of other actors including educational businesses, property developers, transnational migrants and local and national state actors.     

Substitutes for water are being found in the Middle East and North Africa

Evident mismatches exist between the demand and supply of water in many countries particularly in the semi-arid and arid worlds. The resulting food gaps which concern both the national governments of these countries as well as the international agencies which extend assistance to them, appear at first sight to pose challenges beyond the economic and political capacity of peoples and institutions to make the necessary adjustments. The institutions with responsibility for the allocation and planning of water use at international, national and local levels do not seem to be robust enough, or informed enough, to provide the necessary leadership to ensure that scarce water is used sustainably.It will be argued that despite the great difficulties which governments and users face in coping with the need to manage water so that it brings a sound return, as well as according to principles of equity, safety, and ecological sustainability, everywhere there are examples of conflict over water being avoided. And while the avoidance of conflict can in many cases be calculated to have been at a cost to the environment, nevertheless, to date conflict of a hot nature has been avoided. Case studies from a region seen to have the worst water resource future outside the industrialised world, the Middle East and North Africa, will be discussed which exemplify the numerous strategies adopted by countries in their various ecological, economic and political circumstances. A fortunate few governments have substituted oil capital for water while others have filled the food gap, which is generally an expression of the water gap, by ceding economic and political autonomy.
