The Intergovernmental Panel on Climate Change (IPCC) report, initiated in 1988, is complete, was debated at the Second World Climate Conference in November, 1990 and was subsequentty submitted to the United Nations General Assembly. IPCC: (i) asserted the reality of humanity's disturbance of the natural climate system; (ii) demanded studies to improve our knowledge of processes vulnerable to climatic changes: and (iii) called for policy responses to mitigate and adapt to these changes. Two fundamental issues are: how will global climatic change affect natural resources and human population and how will the impetus towards policy responses, particularly greenhouse gas emission reduction treaties, affect industry, the economy and trade? A necessary first step in the highly desirable and geographical aspiration of striving to link numerical climate modelling to the predictions of socioeconomic systems is increased awareness and improved understanding of current physical and social models. In this paper I review the status of numerical climatic modelling especially as it pertains to scenarios of the effects of human-enhanced greenhouse warming. These projections are of futures which are themselves the result of socio-economic predictions. Development of appropriate adaptive strategies depends crucially upon improved simulation of the continental near-surface climate and on improved spatial resolution of climate models by at least two orders of magnitude. Such increased resolution is likely to demand a thousandfold increase in computing power. The physical results of global climatic change are likely to be less significant than the social and economic effects resulting from international agreements on emission reduction Recent shifts in international research and policy responses place today's studies of global climatic change firmly at the focus of human-environment interactions and hence at the core of modern geography.  相似文献

This contribution assesses the ‘converging divergence’ thesis that global inequality is falling and national inequality is rising. The article argues that falling global inequality is primarily due to China's development and that national inequality has risen in some developing countries and fallen in others. In light of the dominance of China's development in the global picture, questions arise as to what has changed and what has not changed outside of China. A set of changes and continuities is presented. It is then argued that these changes and continuities provide for the contemporary relevance an older conceptual lens — that of ‘late development’.  相似文献

环境营造:中国历史上人类活动对全球变化的贡献   总被引:5,自引:0,他引:5  
在古代-近现代中国,历时数千年人类活动展开所具有的时空条件、土地面积和经营方式、人口规模和质量、社会组织形式、社会形态延续条件等基本内容,在世界各国中是难有其比的。国外许多科学家将加大力度利用丰富的历史文献(中文为主),用于研究和解释人类活动对地球环境变化可能具有的作用和影响份额的希望,寄托在中国科学家和历史学家身上,是有充足理由的。本文认为,发挥国情和历史地理专业优势,现阶段可以视为全球变化研究框架中的重要内容是(1)土地利用与土地覆盖格局的变化;(2)流域生命-文化环境的构成及其成长;(3)河湖海系统的演变;(4)制度和政策因素怎样调节人类的社会经济行为;(5)提取和整理对地球环境有重大影响的自然、人文事件。为了对人类活动引起环境变化的影响和作用作出较为准确的判断,研究中需要做好的事项有(1)排查文献资料中的人为主观撰述因素;(2)核实人类活动可以影响的范围或方面;(3)分析人类活动本身包含的复杂性因素;(4)充分估计自然本身的力量;(5)尊重和学习其它专业的研究方法及其实验结果。时至今日,科学事业发展的形势,已经将历史学加入自然科学研究计划的工作提到了研究时间表上。  相似文献

A prominent urban geographer presents a sweeping review essay on monumentality in the urban design of world cities. After outlining a number of the large, grand urban plans and projects of the past and present, he focuses on the four components of monumental urban design: comprehensive conceptions of legible urban form; iconic buildings; integrated urban transportation hubs; and planned downtown and midtown redevelopment projects. Concentrating on the trends prevailing at present and over the near future, the author notes factors that may exert a special impact on emerging world cities in Russia and China and argues for the importance of process in the geography of monumentality.

This article analyses the relationship between the tumultuous religious changes of the sixteenth and seventeenth centuries and the landscape of the British Isles. It examines the immediate impact and long‐term cultural repercussions of the Protestant and Catholic Reformations on perceptions of and practices associated with the natural world and physical environment, as well as the influence exerted by intellectual and cultural trends associated with developments in science, medicine, and antiquarianism. Reformed theology fundamentally undermined traditional assumptions about the presence of the sacred in the material universe, but the religious ruptures of the era were tempered and complicated by elements of continuity and movements of counter‐reaction. Springs, trees, stones, and other notable topographical landmarks retained powerful religious resonances after the Reformation. Potent reminders of the pre‐Reformation past, they also provided a stimulus to the making of new myths and legends and acted as catalysts of the transformation of social memory.  相似文献

This paper discusses a fieldwork exercise in development geography undertaken by students in the UK. Based on community engagement in partnership with refugee and black minority communities in Liverpool, it explores how such fieldwork can deepen understanding of development geography, contribute to global citizenship and nurture personal skills. Students of development geography engaged in real-world experiential learning about the complexity of the social, economic and cultural issues facing refugees and black and racial minority groups, and the processes by which these change and evolve. The challenges of the fieldwork were positively received as students gained relevant and useful insights from their interaction with community stakeholders.  相似文献

One of the relatively neglected aspects of studies of industrial districts is that of processes of innovation and structured change. In the paper, a preliminary theorization is offered, with evidence from a case in Tuscany. The paper concludes that creative capacities embedded at the local level may be valuable in this respect.  相似文献
