A Strategic Project Appraisal framework for ecologically sustainable urban infrastructure

Actors in the built environment are progressively considering environmental and social issues alongside functional and economic aspects of development projects. Infrastructure projects represent major investment and construction initiatives with attendant environmental, economic and societal impacts across multiple scales. To date, while sustainability strategies and frameworks have focused on wider national aspirations and strategic objectives, they are noticeably weak in addressing micro-level integrated decision making in the built environment, particularly for infrastructure projects. The proposed approach of this paper is based on the principal that early intervention is the most cost-effective and efficient means of mitigating the environmental effects of development projects, particularly macro infrastructure developments. A strategic overview of the various project alternatives, taking account for stakeholder and expert input, could effectively reduce project impacts/risks at low cost to the project developers but provide significant benefit to wider communities, including communities of future stakeholders. This paper is the first exploratory step in developing a more systematic framework for evaluating strategic alternatives for major metropolitan infrastructure projects, based on key sustainability principles. The developed Strategic Project Appraisal (SPA) framework, grounded in the theory of Strategic Environmental Assessment (SEA), provides a means of practically appraising project impacts and alternatives in terms of quantified ecological limits; addresses the neglected topic of metropolitan infrastructure as a means of delivering sustainability outcomes in the urban context and more broadly, seeks to open a debate on the potential for SEA methodology to be more extensively applied to address sustainability challenges in the built environment. Practically applied and timed appropriately, the SPA framework can enable better decision-making and more efficient resource allocation ensuring low impact infrastructure development.     

Using Participatory Rural Appraisal to explore coastal fishing in Badagry villages,Nigeria

Fish production and marketing are as old as the rural communities involved in the lucrative occupation in Badagry area of Lagos State, Nigeria. A random sampling of 200 fishermen using Participatory Rural Appraisal techniques (PRA) in five Badagry villages was used to explore coastal fishing and socio-economic development in the study area with a view to enhancing local productivity and sustainability. The findings show that an average fisherman in Badagry is aware of the resources available in his environment, and can affect productivity levels positively if given adequate incentives. There are two lessons from this study; one has to do with what PRA tells us about the fishing community, the other is the importance of facilitators that have, amongst other things, good listening skills. The experience also revealed that field workers’ ability to listen and learn from local fishermen was a critical factor in collecting in-depth information that could be used for rural community planning.     

天然改性阳离子絮凝—杀菌剂CG—C处理油田废水

ＣＧ－Ｃ是天然改性阳离子型絮凝一杀菌剂，由高，中，低分子组成，文章研究了它对模拟油田废水的净化和杀菌性能，试验表明，ＣＧ－Ｃ型药剂可以实现低剂量下的一次投药同时达絮凝与杀菌的目的，其杀菌效果优于投放单一杀菌剂。     

工业产品生命周期环境成本评估方法初探

产品环境成本内在化是解决其环境问题的一个重要经济手段。生命周期评价方法和传统的会计制度都不能提供产品的环境成本信息。而目前逐渐兴起的环境会计制度也多关注与产品生产直拉相关的环境成本，缺乏全过程的思想，要真正满足可持续发展的需要，就必须开发适于其生命周期环境成本评估的方法。文章在介绍传统的成本划分方法基础上，提出了生命周期环境成本的概念及其评估方法。     

铁岭市各类大气污染源浓度贡献分析

利用铁岭市2004年的PM10（可吸入颗粒物）和SO2（二氧化硫）大气环境监测资料、污染源排放清单资料和气象资料,以及AERMOD模型（1）进行了铁岭市大气环境质量区域评价。结果表明：铁岭市低架源对地面浓度的贡献较大,高架源对地面浓度的贡献相对较小。

PRA和GIS在小尺度土地利用变化研究中的应用

论文借助PRA,结合实地测量和GIS,以宁夏南部山区的上黄村为例对小尺度区域的土地利用变化进行了初步研究。重建和恢复了其25年来各时期的土地利用过程,绘制了上黄试区不同时期的土地利用空间变化图,并对其土地利用的数量及空间变化进行了分析。结果表明:在研究期内,从数量上看,耕地和林地变化最为显著,年变化率分别达到了8.0%和9.2%;从空间分布变化来看,主要表现为耕地向林地、草地及园地转变。
