Who's afraid of zoning?

Changes to the British Planning System aimed at simplification of controls have introduced the concept of zoning. Far from being a limited and rigid concept, the Australian approach to zoning offers some interesting possibilities because of its balance between flexibility and certainty. The principal elements of an Australian zoning system are described and discussed to demonstrate the opportunities available to planners adjusting to changing political and economic climates. It is shown that it is possible to combine strategic planning with greater certainty in development control.     

流域生态补偿机制的进化博弈分析

利用进化博弈的复制动态方法,建立流域生态补偿的进化博弈模型,研究利益相关者基于利益因素的动态博弈特征。结果表明,在上下游的"环境责任协议"制度中引入激励机制—监督惩罚成本后,流域生态补偿机制中的利益相关者最终进化成哪种策略取决于对下游地区补偿不能及时到位的行为的惩罚力度(即监督惩罚成本的大小)、下游地区对上游地区的生态补偿量以及上游因损害生态资源而给下游地区的赔偿量。通过调整这三个关键因素,可促使(保护,补偿)成为纳什均衡,从而有效地激励人们从事生态投资并保持这种投资的持续性,实现流域生态环境的可持续发展。

Food web assessments in the Baltic Sea: Models bridging the gap between indicators and policy needs

Ecosystem-based management requires understanding of food webs. Consequently, assessment of food web status is mandatory according to the European Union’s Marine Strategy Framework Directive (MSFD) for EU Member States. However, how to best monitor and assess food webs in practise has proven a challenging question. Here, we review and assess the current status of food web indicators and food web models, and discuss whether the models can help addressing current shortcomings of indicator-based food web assessments, using the Baltic Sea as an example region. We show that although the MSFD food web assessment was designed to use food web indicators alone, they are currently poorly fit for the purpose, because they lack interconnectivity of trophic guilds. We then argue that the multiple food web models published for this region have a high potential to provide additional coherence to the definition of good environmental status, the evaluation of uncertainties, and estimates for unsampled indicator values, but we also identify current limitations that stand in the way of more formal implementation of this approach. We close with a discussion of which current models have the best capacity for this purpose in the Baltic Sea, and of the way forward towards the combination of measurable indicators and modelling approaches in food web assessments.

中国自来水行业市场化战略的经济学分析

我国自来水行业长期以来实行国家经营,由于缺乏竞争以及行业监管不足,致使供水不足、行业经营效率低下、成本较高,因此,采取市场化模式势在必行.对此,我国自来水行业从1992年开始实施以打破垄断、提高效率与改善服务质量为目标的市场化改革,并取得了一定的成效,但是还是存在许多不足.在介绍了我国自来水产业市场化模式的发展历程,并运用经济学的相关理论和实证方法,来分析中国自来水市场化模式.
