生态环境空间分级管控策略研究

生态环境空间分级管控是为了确保各级尺度下的生态环境空间充分发挥其生态服务功能所采取的管理控制手段与途径,同时给城市生态环境空间的管控提供依据,在不同尺度下,生态环境空间需按照不同精细度的管控方法和不同的土地空间单位进行分级,生态环境空间分级管控主要包括:省域尺度生态环境空间的管控、市域尺度生态环境空间管控和在主城区尺度下生态环境空间管控。通过3种尺度不同管控方法和策略的有效衔接,从宏观、中观和微观3个层次保证了生态规划的完整性和连续性,使生态系统服务真正发挥其价值。     

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.     

A review of Defra's approach to building an evidence base for influencing sustainable behaviour

Defra's approach to influencing people to live sustainably has evolved considerably since 2005 when the Sustainable Consumption Roundtable called for greater efforts by Government to better understand people, and how to influence changes in the way they behave. In response, Defra has developed a substantial evidence base devoted to improving understanding of the drivers for sustainable behaviours and how these can be applied to develop more effective environmental policies and programmes.A core focus of Defra's research programme has been to identify and build on existing research and evidence which has the potential to inform new and innovative policy approaches. In some cases, this has involved work which looks at particular behavioural drivers, such as habits and norms, considering how these insights can inform and improve outcomes from policies that aim to influence citizen's behaviours. Other work has focused on operationalising this knowledge through trials and demonstration projects with an aim of understanding the practical implications of applying them, and measuring the benefits they can provide.This paper reviews the key strands of Defra's behavioural research programme and some of the tools the department has used to apply this research. It considers Defra's work in building an evidence base that can be embedded into policy making and concludes with some insights drawn from this evidence. These address both why people are likely to act and why they might not, and best practice principles for delivering change.     

U.S. Electric Utilities and Renewable Energy: Drivers for Adoption

Renewable energy can address rising demand for energy, environmental protection, energy security, and job creation. This paper assesses resource, economic, social, and political drivers for the adoption of renewable energy. Analysis of the data collected from over 100 interviews with utility managers reveals that production tax credits significantly influence the percent of renewable energy in a utility's portfolio. The availability of renewable energy resources, economic drivers, social influences, and political drivers such as renewable portfolio standards and government grants are not significant drivers. Understanding these drivers can help electric utilities, governments, and other stakeholders with their efforts to reap the benefits of renewable energy.     

Information requirements of integrated environmental policy experiences in the Netherlands

During the last few years in the Netherlands an integrated environmental policy has been developed. Solving environmental problems by means of effective and efficient solutions requires that the entire environmental cycle be considered in order to take all relevant compartments and aspects into account. Four different phases can be identified during the treatment of an environmental problem by management: recognition, formulation, solution, and control.Some qualitative and quantitative aspects of the information demand of environmental policy are explored. Special attention is given to the consequences of the integral approach in environmental policy in terms of information requirements. The process of information supply starts with an analysis of the demand. Subsequently data from the environmental cycle have to be selected, aggregated, and presented adequately. Further, integrated environmental policy puts increased demands on the associative power of environmental information systems.
