全球化背景下城市文化地理研究的新趋势

文化全球化背景下,在城市的快速转型过程中,城市文化发展和演进面临更多新要素的触动:"异质文化"日渐冲击或渗透着城市本底文化,影响城市文化发展的主要因子也更多从自然环境要素始向人文因素转变,即城市本底文化生存的"土壤"正在发生革命性改变,从而使城市文化表现出更多时代内涵、时尚意韵和新景观。本文基于国内外相关研究进展,讨论全球化背景下城市文化地理研究的新态势,以期对新时期国内文化地理学的研究有所裨益。

“This is our land”: collective violence,property law,and imagining the geography of Palestine

This study seeks to explain the origins of two types of violence occurring on the Palestinian landscape, the erasure of Palestinian farms and the demolition of Palestinian homes. Such violence has two sources. One source derives from an enduring practice of meaning-making about geographical places that has inspired groups with territorial ambitions to seize control of the landscapes they covet and is referred to by Edward Said as the crafting of “imaginative geographies.” The second source focuses on changes in property rights that follow when groups with territorial ambitions succeed in seizing control of coveted land. It is the imagined geography of Palestine as a homeland for the Jewish people, first framed by Zionists of the late 19^th century and absorbed into the practices of Israeli state-building, and the changes in property rights inscribed into the Palestinian landscape following Zionist and Israeli military conquests in 1948 and 1967, that lie at the core of violence directed against the Palestinian farm and home today. This process of imagination, legal transformation, and violence is part of a longstanding lineage of dispossession that includes the English enclosures and the taking of land from Amerindians on the Anglo-American colonial frontier.     

Dispossession by Accumulation? Mining,Water and the Nature of Enclosure on the Bolivian Altiplano

Abstract: This paper examines processes of primitive accumulation and livelihood dispossession on the Bolivian Altiplano. Through empirical examination of the social and environmental effects of mining waste, the paper demonstrates that indigenous campesino community members are experiencing livelihood dispossession by way of three interrelated forms of accumulation: accumulation of toxic sediments on agricultural fields; accumulation of water and water rights by mining firms; and accumulation of territory by mining operations. In the case under examination, full proletarianization is not taking place, and processes of dispossession are not a “fix” for an overaccumulation crisis. The paper argues for greater attention to the contingent role of nature's materiality in processes of dispossession and accumulation.     

Diamond Mining in Canada's Northwest Territories: A Colonial Continuity

Abstract: The Canadian diamond industry has been lauded as a new approach to resource extraction, one whose institutions are characterized by a greater attention to Indigenous rights and the environment. However, an institutional analysis obfuscates the terrain of unequal relations that is the context for the Canadian diamond boom; an analysis of the effectiveness of social and environmental policies in relation to the extraction of diamonds in the Canadian North suggests that there is an intent on the part of those instigating this extraction (that is, the Canadian state, Canadian capitalist interests and international capitalist interests) to protect the Northern environment and to provide economic benefits to Northern Indigenous communities. This piece argues, instead, that this assumption is erroneous and that the Northern mining industry is part of Canada's project of internal colonization of Indigenous communities, a project that has intensified and expanded in the neoliberal era.

1949—1950年新中国生产救灾的地方实践——以山东省五莲县为例

生产救灾是1949—1950年新中国受灾地区党和政府的中心工作。党和政府强调恢复和发展农业生产是救灾的根本办法。为此,山东省五莲县在冬季因地制宜,重点开展固定代耕和积肥运动,进行了充分的春耕准备;春季则推广良种,及时发放救济粮和贷放贸易粮,保障了农业生产顺利进行。在1949—1950年的生产救灾工作中,党和政府发挥着组织领导作用,采取了积极的救灾方式,既有力地解决了劳动力、畜力不足等问题,又有效地防治了病虫害,从而最终保证了土地适时耕种,迎来了农业丰收。
