Compliance of Australian threatened species recovery plans with legislative requirements

Recovery plans are the main documents supporting management decision-making for threatened species. We evaluated Australian recovery plans to assess their appropriateness as conservation and management planning instruments. Six legislative requirements (species information and general requirements, species distribution and location, known and potential threats, objectives, performance criteria and actions, duration of the plan, and estimated costs of plan implementation) were used to assess the degree of compliance of recovery plans with the relevant legislation. We assessed all 236 official recovery plans which had been adopted as at January 2006. The results showed that plans were most compliant regarding the setting of objectives, performance criteria, recovery actions, and duration of plan. Most plans included a single performance criterion that was generally related to the population status of target species. Improvement is required in relation to identification of current threats and critical habitats, and the establishment of basic elements of monitoring and evaluation for measuring recovery progress. Gaps in ecological information are the main factors affecting adequate compliance with legislative requirements as opposed to managerial information (e.g. clarity in establishing the implementation schedule, costs and resource allocation). Planning deficiencies could be addressed by improving the recovery planning guidelines and more carefully reviewing the drafting and adoption of new plans.     

The burden of proof in trade disputes and the environment

The WTO leaves discretion over environmental policies to its members, but requests that a fundamental non-discrimination principle is respected: National Treatment (NT). The provision seeks to prevent protectionist use of domestic policy instruments, requesting that when an imported product is sufficiently similar to a domestic product, they are treated identically. WTO adjudicators will often face severe informational problems in environmental disputes. Important for the practical implementation of NT is therefore the allocation of the burden of proof (BoP). This paper highlights basic implications of the BoP for the occurrence of judicial errors, for the environment and for welfare, using a setting where NT serves its intended role of supporting negotiated tariff liberalization. The paper suggests that NT may indeed constrain environmental policies, but that this may be desirable from an efficiency point of view. Also, BoP rules that benefit the environment may not benefit global welfare, and conversely.     

The influences of climate and hydrology on population dynamics of waterbirds in the lower Murrumbidgee River floodplains in Southeast Australia: Implications for environmental water management

Restoration of waterbird diversity and abundance is a key objective of river system management in Australia. Therefore, understanding the effects of climatic and hydrological variables on waterbird population dynamics is fundamental for successful river restoration programs. We investigated the population dynamics of waterbirds (total abundance) and seven functional waterbird groups in the floodplains of lower Murrumbidgee River. We found a general declining abundance trend from 1983 to 2007, except for the deep water foragers. We modelled the relative contribution of the climatic and hydrological factors to waterbird population decrease using the generalized additive model (GAM) framework after identifying the negative binomial distribution. Most of the seven functional groups were positively related to both annual rainfall and water usage, defined as the total water volume intercepted by the river reach, and the models indicated that rainfall was slightly more important. Temperature also played a role in waterbird abundance: the maximum summer temperature negatively influenced the abundance of dabbling ducks, shoreline foragers and fish eaters, while the minimum winter temperature positively affected the abundance of dabbling ducks and shoreline foragers. Overall, our results support the practice of providing environmental water for sustaining waterbird populations. However, environmental water provision is likely to be most effective when timed to coincide with antecedent rainfall.     

Evaluating coal bed methane investment in China based on a real options model

In this paper, a real options based binominal lattices model for the investment of coal bed methane (CBM) is conducted. CBM prices and market demand are incorporated into the model as the predominant uncertain factors and it is solved by using the bidimensional binominal lattices approach. Then the model is employed to evaluate the investment in CBM projects in China, and the effect of related policies is analyzed. The empirical results demonstrate that the model can be used to offer a better explanation of why the CBM industry has developed slowly in China from an investment perspective. It is found that the current policy environment is not positive enough to attract investment in the CBM industry. Among various factors, CBM prices yield the most significant effect on stimulating investment in CBM development. Increasing the price subsidy is also an effective policy to stimulate investment and promote the development of the CBM industry in China.     

Landfill diversion in a decentralized setting: A dynamic assessment of landfill taxes

We analyze the process of landfill diversion and its main determinants, by embedding the dynamics in a frame where economic, geographical and policy variables come into play. In addition to structural and economic drivers, we primarily investigate whether the Italian tax has been effective in supporting landfill diversion. Although the Italian landfill tax dates back to 1996, the oldest in the EU, its effectiveness in terms of landfill diversion has not been assessed yet. The complexity primarily derives from the decentralized regional implementation and the absence of a full coherent dataset covering all regions. We merge this new and original data on taxes to an integrated dataset which includes economic, waste and policy variables at regional level over the period 1999–2008. Panel regressions show that the effect of tax is significant, even when taking into account for its possible endogeneity. Regions that have increased such taxes have improved waste disposal performances over time. Landfill taxes are surely not the only instrument policy makers might introduce, but they seem to play a relevant role in the evolution of Italian waste disposal performances.     

A community-based approach to low-income residential energy efficiency participation barriers

Financial barriers are often cited as the principle impediment to the adoption of energy efficiency measures. Since 1976, the US Department of Energy's Weatherisation Assistance Programme (WAP) has provided state block grants for no-cost, low-income energy efficiency retrofits. Yet, millions of low-income American households lack affordable, reliable, and efficient energy access. The American Recovery and Reinvestment Act of 2009 boosted WAP's annual appropriation from $230 million to $5 billion, requiring states to explore innovate approaches to quickly increasing programme participation. Community-based energy programmes have shown success for overcoming various barriers and increasing participation in the adoption of energy technologies. This case study explores a community-based approach to scaling WAP-funded energy efficiency retrofits in a cluster of five urban, low-income, majority African-American neighbourhoods, known as the Green Impact Zone (GIZ), in Kansas City, Missouri. Findings from interviews with GIZ stakeholders suggest that local context is important to how energy efficiency participation barriers manifest. The targeted, community-based approach to WAP created institutional capabilities for increased recognition of participation challenges and facilitated opportunities for alternative solutions that may otherwise have been overlooked under the standard self-referral implementation of WAP. Lastly, effective implementation of WAP required policy workarounds that recognised the unique characteristics and needs of the target community.     

西部大开发政策效应评价

经过15年的西部大开发,西部各个省份的综合发展水平怎样?西部大开发是否显著缩小西部与东部地区在综合发展水平和经济增长的差异?哪些政策起到了关键作用?是本文将要探讨的问题。研究方法主要是通过模型与数据的实证研究方法对西部大开发的政策效应进行评价。内容包括:一是通过构建包含了社会、经济、科教与文化、对外开放和资源与环境五大类25个分项指标的综合发展水平评价体系,使用从1997到2013年31个省市的指标数据,并计算出综合评价值来考察西部大开发政策对西部地区各个省份整体发展的影响。从评价值排名上来看发现只有重庆、陕西、四川和内蒙古综合发展水平排名提升明显,而新疆、宁夏和青海发展差距还在拉大,其他省份排名变化不大。从分类指标来看,西部地区整体上社会发展和资源环境与生态提升较为明显,说明中央对于公共服务的转移支付和"退耕还林还草"等保护环境与生态的政策起到了一定的成效。二是选取了交通基础设施建设、中央转移支付和税收优惠这三个主要政策作为计量模型的政策变量,分别考察西部大开发整体和分项政策对于综合发展水平和经济增长率的影响。通过系统GMM方法估计整体西部大开发整体政策效应,以2000年前后对比,政策实施对GDP增长率的提升并不显著,综合发展水平也没有收敛。而以2008年为时间节点,综合发展水平和经济增长速度都得到了显著提升。通过DID估计分项政策,结果表明基础设施投入和转移支付能够有效提升综合发展水平和经济增长速度,税收优惠提升相对较弱。本文建议:在交通基础设施投入方面继续对西部地区予以倾斜,特别是建设西部地区通往东中部地区的交通大通道;培育和完善西部地区的市场经济体系,政府较少干预企业投资决策;加强对于西部落后地区、偏远地区的公共产品投入,加强扶贫工作。     

Science–policy processes for transboundary water governance

In this policy perspective, we outline several conditions to support effective science–policy interaction, with a particular emphasis on improving water governance in transboundary basins. Key conditions include (1) recognizing that science is a crucial but bounded input into water resource decision-making processes; (2) establishing conditions for collaboration and shared commitment among actors; (3) understanding that social or group-learning processes linked to science–policy interaction are enhanced through greater collaboration; (4) accepting that the collaborative production of knowledge about hydrological issues and associated socioeconomic change and institutional responses is essential to build legitimate decision-making processes; and (5) engaging boundary organizations and informal networks of scientists, policy makers, and civil society. We elaborate on these conditions with a diverse set of international examples drawn from a synthesis of our collective experiences in assessing the opportunities and constraints (including the role of power relations) related to governance for water in transboundary settings.     

The use of indicators in environmental policy appraisal: lessons from the design and evolution of water security policy measures

Drawing up environmental policy options is a complex activity which involves defining and weighing the merits and risks of various alternative courses of action governments could pursue. In its modern version, this task typically involves formal policy analysis or ‘policy appraisal’, that is, policy work specifically undertaken to generate and evaluate policy options in order to address problems or issues on a policy agenda. Indicators play a powerful but under-investigated role in this process. To shed light on this issue, the paper conducts a case study of the design and evolution of policy indicators in water security policy formulation, examining both their utilization and impact. The paper documents the origins of water security policy indicators; assesses their relevance and influence in policy formulation and identifies the reasons for the emergence of certain preferred indices, despite their having several well-known limitations. In particular, the discussion flags the significance of the political advantages surrounding their ease of use and interpretation, rather than their technical merits, as a key factor affecting the continued utilization and influence of specific indicators in environmental policy and planning.
