南水北调中线工程对汉江中下游工业发展的影响

南水北调中线工程计划从丹江口水库向我国北方每年调水１４５亿ｍ＾３,汉江丹江口以下地区的水资源量将随之相应减少。汉江中下游地区是湖北省盐化工、机械、石油、食品、化肥、电力的重要生产地区,是湖北省的汽车工业走廊,其经济在湖北省占有举足轻重的地位。由于经济的迅速发展,下世纪工农业生产和人民生活对水资源的需求将从现在的１４０亿ｍ＾３增加到２５０亿ｍ＾３以上,需水量将达到水资源量的５８％,潜伏着严重的水资源     

Deliberation and ecological democracy: from citizen to global system

ABSTRACT

Ecological democracy confronts a challenge of not only reconciling democracy and ecology, but doing so where human activities and their environmental consequences are increasingly global. Deliberative scholars dealing with these issues emphasise reflexive governance, involving the contestation of discourses, as part of the solution, mostly aimed at high-level institutions and intergovernmental cooperation. However, even at this level democracy demands responsiveness to the citizen. To this end, the paper explores citizen-level deliberation to inform possibilities for ecological democracy writ large, via a growing literature on deliberative governance and polycentrism. Different system levels are connected via ecologically reflexive capacity and the discursive conditions under which it is enhanced, including in small-scale minipublics. This understanding informs mechanisms for ‘scaling up’ deliberative quality to the wider public sphere via regulating the manipulation of public discourse. Minipublic deliberation, properly harnessed, can serve to decontaminate public debate of anti-reflexive strategic arguments and reshape public discourse. Such anti-reflexive strategies seek to shape the public will, specifically by de-emphasising ecology via intuitive arguments that short-cut public reasoning. Acting as discursive regulatory trustees, minipublics can improve reflexivity in the wider system via a nested polycentric approach that discursively connects citizens’ deliberation to the global system both horizontally and vertically.     

碳中和愿景下电力部门低碳转型路径研究

碳中和愿景一方面加速了全社会电气化发展,致使电力需求持续增加,另一方面对尽早实现零碳电力提出要求,电力部门低碳转型进程更加紧迫而复杂。本文首先定性分析碳中和背景下电力部门的总体转型思路和技术不确定性影响,其次采用电力部门与终端部门耦合的C~3IAM/NET模型对电力需求进行预测,同时根据关键低碳技术发展的保守预期和积极预期设计多种情景,以开展电力低碳转型路径优化和成本效益研究。结果显示,发电碳排放量峰值可能出现在40亿～42亿吨,在2049—2060年有望实现零碳电力,电力部门低碳转型速度和效果因技术不确定性而存在明显差异。2021—2060年电力低碳转型累计投入为171万亿～180万亿元,CCS技术累计减排贡献超过250亿吨,可再生能源电力占比需达到68%以上,风电和光电将成为主要电力。     

中国与欧美非道路移动机械排放标准对比分析

随着非道路移动机械保有量与使用量的不断增加,其排放造成的环境问题日益严重,相关的防治策略研究亟待加强。本研究首先总结了中国与欧美对非道路移动机械类型的划分方式及标准;其次,对中国与欧美的非道路移动机械排放标准进行归纳;最后,对现行中国与欧美的非道路移动机械排放标准进行了全面对比分析,分析发现,国内标准与欧美标准之间仍存在显著差距,以期为国内制定科学的非道路移动机械排放标准提供参考,为污染物防治策略的制定提供理论支撑。

Poverty Reduction and Sustainable Development

The prominent place of the chapter on poverty in the Johannesburg Plan of Implementation (JPI) is totally in keeping with the priority given to poverty reduction in the development thinking of the international community of today. The Johannesburg process did not lead to any new insights or new commitments in the fight against poverty. Section one sets out a factual comparison of the poverty chapters in Rio's Agenda 21 (AG21) and in the JPI. Section two reviews the conceptual links between poverty reduction and sustainable development, since poverty is used both as a dependent and as an independent variable. This analysis shows a shift in the function of growth as related to environmental protection. Section three explores the naturalization of development thinking in its economic and social dimensions and shows how this affects the policy options for social protection. I also explain how social and environmental sustainability have become elements of risk management and how are both aimed at conflict prevention and enhanced growth. Finally, in section four three lines of action are suggested to enhance the emergence of a socially meaningful sustainable development agenda that, ideally, would make poverty reduction strategies redundant.     

Food and hunger in Sub-Saharan Africa

Sub-Saharan Africa is by far and away the most disadvantaged of the world's three main developing regions. Worse, its situation has mostly been deteriorating for much of the past several decades. Its agriculture is severely under-productive, and per capita food supplies have been steadily dwindling. Its environments and natural-resource base, characterised by water deficits, soil erosion, fuelwood shortages, rudimentary agro-practices, and grossly inadequate infrastructure, are generally unfavourable for sustainable agriculture. The population has expanded until it far exceeds carrying capacity, yet its growth rate is the highest in the world. The region also suffers from more disease than any other region. There is widespread and deepening poverty. As a result of these and other problems, and despite major food imports, two-thirds of the people are malnourished, one-quarter of whom endure outright hunger, even semi-starvation. Both these proportions appear set to keep on increasing both relatively and absolutely. Were these problems to persist with their decades-long trends, there could eventually arrive a stage when much larger numbers of people would succumb to terminal malnutrition, precipitating a human tragedy of unprecedented proportions. Fortunately, success stories demonstrate that solutions are available, on the part of both governments concerned and international agencies. Because of ignorance, or rather ignore-ance of the potential mortality disaster ahead, however, not nearly enough has been done to address the challenge with the energy and urgency to match its scale.     

What happens to the state in conflict?: political analysis as a tool for planning humanitarian assistance

It is now part of received wisdom that humanitarian assistance in conflict and post-conflict situations may be ineffective or even counterproductive in the absence of an informed understanding of the broader political context in which so-called 'complex political emergencies' (CPEs) occur. Though recognising that specific cases have to be understood in their own terms, this article offers a framework for incorporating political analysis in policy design. It is based on a programme of research on a number of countries in Africa and Asia over the last four years. It argues that the starting-point should be an analysis of crises of authority within contemporary nation-states which convert conflict (a feature of all political systems) into violent conflict; of how such conflict may in turn generate more problems for, or even destroy, the state; of the deep-rooted political, institutional and developmental legacies of political violence; and of the difficulties that complicate the restoration of legitimate and effective systems of governance after the 'termination' of conflict. It then lists a series of questions which such an analysis would need to ask--less in order to provide a comprehensive check-list than to uncover underlying political processes and links. It is hoped these may be used not only to understand the political dynamics of emergencies, but also to identify what kinds of policy action should and should not be given priority by practitioners.     

Cyclone mitigation, resource allocation and post-disaster reconstruction in south India: lessons from two decades of research

This paper opens with a history of development and disaster-prevention strategies in a cyclone-prone area of the east coast of India and traces the evolution in the area of British and Indian governments' programmes and policy over a century. Research over the last 20 years has shown, however, that the programmes and policies have failed to balance economic growth with safety. Resources intended for the benefit of all have been diverted by alliances of powerful people to a small minority, and recent developments have reduced the physical protection of the area. The result is that increasing numbers of people are vulnerable to the effects of cyclones and floods. The findings suggest that the best way to reduce vulnerability is to improve the socio-economic standing of the most vulnerable and for this to happen these people must have an assured income based on assets that will enable them to acquire social and economic credit-worthiness within the local economy. This paper presents evidence that suggests that non-governmental organisation (NGO)-supported co-operatives are the best way to achieve this through self-help and self-employment schemes. It also suggests that NGOs should be encouraged to take up environmentally and ecologically beneficial activities involving the poorest groups in the communities, in this way combining sustained self-employment with environmental protection.
