Ecological restoration often depends on substantial funding to be initiated and sustained. So far, the dominant strategies to fund it have been philanthropic altruism or regulatory compulsion. Both make important contributions, but the commercial sector is a further source that has thus far not played a significant role relative to its potential. Just as philanthropic and regulatory strategies are both modulated by the law, so too law shapes the commercial sector's participation in ecological restoration. Corporate law and its market context are particularly significant, and they are both a potential hindrance and opportunity. Some options for law reform are available to improve the contribution of the business sector to restoration. 相似文献

武夷山国家公园是中国正式设立的第一批国家公园之一, 其所处的武夷山脉在动物地理区划上是东洋区南亚亚区华南小区、东洋区东亚亚区华东小区的分界线。为查明武夷山国家公园及其周边的鱼类区系和多样性现状, 本研究在梳理历史研究资料的基础上, 对调查区域内的崇阳溪、麻阳溪、九曲溪、北溪和铅山河5条河流进行了实地调查, 从物种多样性和功能多样性两个层面对武夷山国家公园及其周边地区鱼类多样性水平进行了分析。结合历史数据, 武夷山国家公园及其周边地区分布的土著鱼类为113种, 隶属于5目17科61属, 其中以鲤形目鱼类为主, 共82种, 占物种总数的72.6%, 其次为鲈形目, 共16种, 占总数的14.2%。受威胁鱼类3种, 包括2种国家II级野生水生保护动物, 即胭脂鱼(Myxocyprinus asiaticus)和花鳗鲡(Anguilla marmorata)。武夷山国家公园的第一优势种为拟腹吸鳅(Pseudogastromyzon fasciatus), 与其周边地区以点纹银鮈(Squalidus wolterstorffi)为第一优势种不同。多样性分析结果显示武夷山国家公园的鱼类物种丰富度指数、多样性指数和均匀度指数均低于周边区域。通过比较调查区域内5条河流的鱼类多样性, 麻阳溪鱼类多样性显著高于其他河流, 铅山河的多样性显著低于其他河流。位于国家公园内的九曲溪鱼类多样性比周边地区的崇阳溪要低。鱼类功能多样性结果显示, 武夷山国家公园的功能丰富度指数显著低于周边地区, 功能离散度和功能均匀度均高于周边地区; 在河流方面, 北溪的功能丰富度显著高于其他河流, 崇阳溪的功能均匀度较高, 九曲溪的功能离散度显著高于其他河流。综合鱼类多样性分析结果, 武夷山国家公园鱼类多样性低主要是自然生境异质性低和人为活动共同作用形成, 而周边地区的河流受到捕捞、水利设施、水质污染等因素的影响。这些干扰改变了鱼类的群落结构, 使得鱼类多样性降低。因此应该加强对该区域的鱼类多样性保护工作, 未来还应进一步开展针对公园内鱼类多样性的调查工作。 相似文献

Background In developing products various requirements have to be integrated including functionality, quality, affordability as well
as environmental aspects. Often conflicting requirements have to be fulfilled. Therefore, multi-dimensional decision support
approaches are necessary.
Methods Here, one approach is to relate the conflicting requirements to each other. Life Cycle Costing (LCC) has the potential to
support the trade-off between some environmental targets and overall affordability targets by including all monetary flows
along the product life cycle (going beyond the well-known costs of ownership by integrating also long-term use and end-of-life
costs). Those solutions can be identified that (a) have the highest efficiencies (where do we get most environmental improvements
per Ϊ and (b) have the highest affordability for the customer along the life cycle. Furthermore, on-costs in the design phase
can be justified in terms of future savings either for the customer or for the recycling of the products. These represent
real business cases for environmental actions. Three types of environmental business cases can be differentiated.
Results and Discussion This paper presents various examples where LCC is integrated into product design. However, there are a number of open issues
in the implementation of LCC within real product development including data availability and uncertainty (future costs/ savings),
level of discounting, accounting and compensation. Various internal case studies done in the last years showed that already
few changes in the costs structure can significantly affect the identi-fied future costs.
Recommendation and Outlook Uncertainties in LCC are higher than in LCA and highest when applied in the stage of product develop-ment, i.e. used to support
DfE action. As a consequence, the result-ing figures can only be seen as directional. Therefore, the use of LCC in Design
for Environment cannot be recommended without major restrictions in terms of guidance, experience/training. The link-age between
LCC and DfE can either be established via (1) experts supporting design teams or (2) as part of a DfE tool. The DfE tool has
to include detailed guidance for interpretation, and its application should be based on a solid training for DfE engineers. 相似文献

How successful are multinational corporations in extending their firm-based environmental standards to their subsidiaries and those subsidiaries' local suppliers in their global production networks in developing countries? We address this question through an in-depth case study of how Motorola, a prominent multinational electronics firm with an extensive global production network, is using a set of firm-based standards to meet several new stringent European Union environmental directives. The case study demonstrates that these firm-based standards appear to be enabling a major subsidiary and its suppliers in one developing economy to reduce the environmental intensities of their production activities. This finding suggests that the firm-based environmental standards of multinationals with extensive global production networks might contribute to a leveling up of environmental standards in subsidiaries and their local suppliers, rather than a "race to the bottom", thus reinforcing the technique or intensity effects associated with open trade, investment, and technology policies. 相似文献

Much of the practice of restoration is conducted by businesses—contractors, consultants, designers, engineers. Restoration businesses interact with a variety of stakeholders to complete projects on time and on budget, and to achieve ecological and business objectives. Our research explores the business perspective in restoration; it is based on data collected from businesses (contractors, consultants, design engineers), agencies, and nongovernmental organizations involved in a Superfund cleanup project in Montana, one of the largest river restoration efforts ever. Our findings highlight several areas restoration businesses must navigate. First, restoration businesses must juggle potentially competing goals, maintaining ecological integrity while achieving profitability objectives. Second, these businesses must manage the risk that arises from variability in the natural environment as well as individuals' risk tolerances. Third, they must navigate the disconnect between “science” and “practice,” including how to best monitor restoration projects. Fourth, they must make decisions about new techniques and innovations. Fifth, on‐the‐ground implementation must acknowledge that personnels' motives and expertise might conflict with original plans. We discuss these findings in relation to relevant scholarly research, offering implications for theory and practice. For example, the business of ecological restoration requires learning over time to be profitable while achieving the desired ecological and social outcomes; restoration businesses leverage monitoring in pursuit of adaptive management and engage “frontline personnel” as important voices in the restoration process. Understanding the business of restoration adds an important perspective in the complex dynamics of social‐ecological systems. 相似文献

Background and Objectives
Irregular and poor quality sleep is common in business process outsourcing (BPO) employees due to continuous shift working. The influence of this on the cardiac autonomic activity was investigated by the spectral analysis of heart rate variability (HRV).Methods
36 night shift BPO employees (working from 22:00 to 06:00h) and 36 age and sex matched day shift BPO employees (working from 08:00 to 16:00h) were recruited for the study. Five minute electrocardiogram (ECG) was recorded in all the subjects. Heart rate variability was analyzed by fast Fourier transformation using RMS Vagus HRV software. The results were analyzed using Mann Whitney U test, Student t-test, Wilcoxon signed rank test and were expressed as mean ± SD.Results
Sleepiness was significantly higher among night shift workers as measured by Epworth Sleepiness Scale (p<0.001). Night shift BPO employees were found to have a trend towards lower values of vagal parameters - HF power (ms2), and higher values of sympathovagal parameters like LF Power (ms2) and the LF/HF power (%) suggesting decreased vagal activity and sympathetic over activity, when compared to day shift employees. However, HRV parameters did not vary significantly between the day shift employees and night shift workers baseline values, and also within the night shift group.Interpretation and Conclusion
Night shift working increased the heart rate and shifted the sympathovagal balance towards sympathetic dominance and decreased vagal parameters of HRV. This is an indicator of unfavorable change in the myocardial system, and thus shows increased risk of cardiovascular disease among the night shift employees. 相似文献9.
This paper discusses the transition toward a circular economy ecosystem (CEE) for plastics by assessing and mapping existing ecosystems and coordinating efforts among ecosystem actors. The PlastiCity ecosystem is used as a case study. The study employs ecosystem analysis and mapping to identify the new activities and actors needed to transition toward a CEE. These include local and eco-friendly transportation, plastic recycling knowledge management, and upgrading the existing recycling infrastructure. The findings emphasize the significance of the joint orchestration of ecosystem actors facilitated by an ecosystem coordinator and knowledge team to achieve a CEE. It presents a tangible and feasible approach to achieving a local plastic CEE. The policymakers are encouraged to support collaborative orchestration efforts among ecosystem actors and establish knowledge management practices that facilitate ecosystem transitions. 相似文献

Demand for sustainably produced biomass is expected to increase with the need to provide renewable commodities, improve resource security and reduce greenhouse gas emissions in line with COP26 commitments. Studies have demonstrated additional environmental benefits of using perennial biomass crops (PBCs), when produced appropriately, as a feedstock for the growing bioeconomy, including utilisation for bioenergy (with or without carbon capture and storage). PBCs can potentially contribute to Common Agricultural Policy (CAP) (2023–27) objectives provided they are carefully integrated into farming systems and landscapes. Despite significant research and development (R&D) investment over decades in herbaceous and coppiced woody PBCs, deployment has largely stagnated due to social, economic and policy uncertainties. This paper identifies the challenges in creating policies that are acceptable to all actors. Development will need to be informed by measurement, reporting and verification (MRV) of greenhouse gas emissions reductions and other environmental, economic and social metrics. It discusses interlinked issues that must be considered in the expansion of PBC production: (i) available land; (ii) yield potential; (iii) integration into farming systems; (iv) R&D requirements; (v) utilisation options; and (vi) market systems and the socio-economic environment. It makes policy recommendations that would enable greater PBC deployment: (1) incentivise farmers and land managers through specific policy measures, including carbon pricing, to allocate their less productive and less profitable land for uses which deliver demonstrable greenhouse gas reductions; (2) enable greenhouse gas mitigation markets to develop and offer secure contracts for commercial developers of verifiable low-carbon bioenergy and bioproducts; (3) support innovation in biomass utilisation value chains; and (4) continue long-term, strategic R&D and education for positive environmental, economic and social sustainability impacts. 相似文献
