理性探源生态危机统筹人与自然科学

当前的生态危机主要是由于人与自然的关系失衡造成的。生态环境恶化造成的可怕后果已经影响了经济和社会的发展。从马克思主义哲学角度对生态危机来源进行深入分析,有助于反思人类在地球上的角色定位,以及应负的责任,重构人与自然关系。

Innovative solutions for averting a potential resource crisis—the case of one-person households in England and Wales

This paper seeks to test the hypothesis that growth in one-person households will increase the domestic consumption of energy, land and household goods in England and Wales. It concludes that if current consumer behaviour of one-person households persists there will be a significant increase in the consumption of all three resources in the future. However, it argues that that many opportunities exist in England and Wales for tackling this problem. For example the new housing programme, increasing ability amongst one-person households to afford “green alternatives” and the search amongst some one-person households for alternative lifestyles (which could be potentially more resource efficient). The paper suggests that providing one-person households with opportunities to live in more resource efficient housing and adopt pro-environmental behaviour could significantly reduce their future environmental impact. Various design, fiscal and awareness-raising solutions are presented in the paper and their viability is assessed. These include ecological homes, collective housing forms, occupancy tax, relocation packages, educational programmes and targeted advertising campaigns. The paper proposes that using a combination of these more innovative solutions to the problem could significantly reduce the future environmental impact of one-person households.

Integrating Environmental Restoration and Ecological Restoration: Long-Term Stewardship at the Department of Energy

With the ending of the Cold War, several federal agencies are reclaiming land through remediation and restoration and are considering potential future land uses that are compatible with current uses and local needs. Some sites are sufficiently contaminated that it is likely that the responsible federal agency will retain control over the land for the foreseeable future, providing them with a stewardship mission. This is particularly true of some of the larger Department of Energy (DOE) facilities contaminated during the production of nuclear weapons. The use of the term “restoration” is explored in this paper because the word means different things to the public, ecologists, and environmental managers responsible for contaminated sites, such as Superfund sites and the DOE facilities. While environmental restoration usually refers to remediation and removal of hazardous wastes, ecological restoration refers to the broader process of repairing damaged ecosystems and enhancing their productivity and/or biodiversity. The goals of the two types of restoration can be melded by considering environmental restoration as a special case of ecological restoration, one that involves risk reduction from hazardous wastes, and by broadening environmental restoration to include a more extensive problem-formulation phase (both temporal and spatial), which includes the goal of reestablishing a functioning ecosystem after remediation. Further, evaluating options for the desired post remediation result will inform managers and policy-makers concerning the feasibility and efficacy of environmental restoration itself.     

Examining Hazard Mitigation Within the Context of Public Goods

/ This paper presents a case study of an American barrier island devastated by a hurricane to show how it is addressing the free-riding problem and protecting its public goods, thereby contributing to hazard mitigation. It examines hazard mitigation and the free-riding problem within the public goods framework. Free-riding is a term used in the public choice theory and common pool resource literature. It is a term used for describing the actions of rational individuals who freely exploit a collective or public good at the expense of others. Free-riding is a major problem faced by public goods. The problem very frequently occurs in the context of hazard mitigation and coastal resource management. Very little is known about the factors that contribute to the promotion of hazard mitigation. This paper identifies some of the important factors that help local institutions provide and sustain hazard mitigation measures. Theoretical and practical implications for hazards research and disaster management policy are presented.     

生态购买是西部生态建设的新战略

生态购买是我国西北地区的强烈要求，也是我国“只能保证过程，不能保证结果”生态建设模式的反思结果。“国有私营”生态购买初衷是政府收购生态建设的产品，既帮助农户脱贫致富，又确保生态建设产品的形成、巩固和转化利用。生态购买以生态建设成果（生态产品）为投资管理的重点，确保生态产品形成效率和转化利用速度，生态效益转化为经济效益。生态购买不仅使生态产品商品化和货币化，实现“生态致富”，更为重要的是培育市场意识、思维、文化，加速培育生态建设市场，充分发挥市场机制的作用，整合社会资源和力量，增强生态建设的实力、能力、吸引力和竞争力。本文经济角度和政策层面．探讨生态购买的产生背景、概念、内涵、原理、功能、方法、程序等。为生态购买的实施提供启发和对策。
