Stewardship of Natural Resources: Definition, Ethical and Practical Aspects

Stewardship is potentially a usefulconcept in modernizing management philosophies. Use ofthe term has increased markedly in recent years, yetthe term is used loosely and rarely defined in landmanagement literature. The connections between thispractical usage and the ethical basis of stewardshipare currently poorly developed. The followingdefinition is proposed: ``Stewardship is theresponsible use (including conservation) of naturalresources in a way that takes full and balancedaccount of the interests of society, futuregenerations, and other species, as well as of privateneeds, and accepts significant answerability tosociety.' A religious interpretation would require thephrase ``and ultimately to God' to be added.Stewardship has both secular and religiousinterpretations and it will be desirable to developboth of these aspects in parallel. A task forphilosophers is to establish whether the ethical basisof stewardship is sufficient to address environmentalconcerns or whether it is necessary to embrace widerethical approaches. Stewardship occupies similarground to several other concepts of use and managementof resources, particularly sustainability. It canbuild on sustainability by encouraging a broader viewof who and what should benefit from managementactivity. In particular, it focuses attention on therole of managers in providing public benefit and onenvisaging other species as a form of ``stakeholder' inmanagement decisions. Stewardship is applicable acrossthe widest range of fields of resource use and alsohas relevance to aspects of land tenure and propertyrights. Application of stewardship will require someadjustments in the roles of private managers/ownersvis-à-vis government. It might providemanagers with an expanded role and, importantly, amore positive image, both of themselves and in theeyes of the public. Stewardship could alsobe developed in a way that has relevance to citizensin general (as opposed to managers and owners ofresources), through their interactions with naturalresources as consumers.     

企业改制对环境管理的影响

实行国有大中型企业扭亏解困,其核心是抓大放小,采取改组、联合、兼并、租赁和股份制等形式,真正建立产权明晰、权责明确、政企分开、管理科学的现代企业制度。因此企业改制会对环境管理工作带来广泛而深刻的影响,同时环境管理工作也面临许多机遇和挑战。江钻股份公司在企业改制过程中积极探索,大胆实践,创造出一条环境管理的新路子。     

Towards a grand deal on subsidies and climate change

Recent studies have identified public subsidies as a principal cause of unsustainable development. Worldwide, governments are spending up to $U950 billion a year on subsidies. Many of these public subsidies fail to serve their purpose and in fact, often turn out as policy failures as they further distort trade and cause environmental harm. The energy sector is among the most subsidized sectors in the world, receiving over $U240 billion per annum of public subsidies. This article highlights current energy subsidies and their implications. The article examines: (i) the global size and distribution of energy subsidies in industrialized and developing countries; (ii) the impact of these subsidies on the economy, equity and the environment and their role as barriers for sustainable development; (iii) the political economy behind public subsidies and the various political and institutional barriers and lock-in mechanisms that cause subsidies to become entrenched in economic and public structures; and (iv) proposals for effective subsidy reform in energy policies, suggesting a global strategy to eliminate energy subsidies. OECD governments are in a position to take the lead, and the UN Framework Convention on Climate Change presents an excellent opportunity of striking a political grand deal and linking the reform of energy subsidies to a meaningful participation of developing countries to the Kyoto Protocol. Moreover, if sinks are to be included in the clean development mechanism (CDM), it is crucial to include the removal of forestry subsidies in the grand deal.     

广州帽峰山林区空气负离子动态及与环境因子的关系

采用定位连续观测方法,研究了广州帽峰山森林公园负离子含量近5年的年、季、月变化及不同天气的变化规律,并以此对帽峰山森林公园的空气质量进行了计量评价.分析了空气负离子含量与环境因子的相关关系.结果表明:林区不同观测区的负离子含量差异较大,山下瀑布空间负离子含量最高.平均水平达达2l 729 ions.cm-3;林内负离子含量年间及月间变化不大,沟谷小溪和山中部瀑布空间由于人为干扰,负离子含量年动态呈现降低趋势,山下瀑布空间年负离子含量维持在20000 iotis·cm-3左右;负离子含量的季节差异显著,春夏季大于冬秋季,夏季最高、冬季最低.空气质量评价系数CI的最低在2月份、最高在8月份.不同天气条件下负离子含量大小顺序为下雨>晴天>阴天.负离子含量与空气温度呈正相关,与空气湿度呈正相关.与空气气压呈负相关.

草原区煤炭开发的生态问题及其税费改革对策

锡林郭勒盟是我国重要的煤炭能源基地,近年来,煤电一体化开发为地区带来经济效益的同时也给环境带来巨大压力,大面积的草原受到破坏和威胁,引发了一系列生态问题,需要在锡盟未来的地区经济发展中引起注意。应该借鉴国际上对煤炭业开征环境保护税的经验,进行我国草原区煤炭业环境保护税费改革的制度设计和政策落实。     

游憩导向下国土空间生态修复的理论与模式

游憩导向下国土空间生态修复是将受损生态空间保护与休闲空间融合的重要手段,是构建山水林田湖草命运共同体与提高人类福祉的重要内容。基于国内外研究现状,界定了游憩导向下国土空间生态修复的概念,提出其应遵循生态系统服务理论、人地关系地域系统理论、区位理论、景观基因理论、大地艺术理论五大理论逻辑。基于实践案例归纳了游憩导向下生态修复模式类型、特征与问题,并提出实践模式的五大优化路径,包括明确功能适宜、效益最优的修复导向,建立多级空间尺度联动的传导机制,提升游憩导向下生态修复地的地方嵌入性,加强修复效果的动态监测评估,构建可持续的建设与运营管理模式,以期为游憩导向下国土空间生态修复和保护提供理论和实践参考。     

绿色金融改革政策的碳减排效应

以绿色金融改革创新试验区政策为例,基于2013~2019年间我国280个地级市的面板数据,运用双重差分法识别绿色金融改革政策是否具有碳减排效应以及其作用机制.研究发现,绿色金融改革政策具有显著碳减排效应（平均值为-0.375）,且呈现逐年递增.机制分析发现,绿色金融改革政策主要通过降低能源消耗强度、提升绿色技术创新水平发挥碳减排效应.此外,绿色金融改革政策具有正向溢出效应,绿色金融改革政策的碳减排效应会辐射到试点区域的周边地区.但绿色金融改革政策并未发挥多污染物减排协同效应.基于此,本文提出了扩大改革试验区范围、加大对绿色金融主体的激励和引导以及发挥绿色金融政策协同效应等政策建议.
