Nowe Tychy: an assessment of a polish new town

No we Tychy is the most prominent and successful of the new towns in post‐war Poland. The paper describes the new town programme resulting from the Regional Plan for Upper Silesia and provides an appraisal of the town's achievement from the point of view of the residents’ living conditions, the usability of the housing stock and the spatial character of the town. The conclusions provide a critique of the process through which the town was developed and built.     

Suitable Housing Placement: A GIS-Based Approach

The intent of this paper is to operationalize some aspects of local sustainability in a suitable development scenario and to compare its energy-use and environmental impacts to trend development. After a discussion of suburban sprawl, local sustainability, and the current state of the Pennypack Creek Watershed in the Philadelphia metro region, these residential location scenarios are presented. The latter were created using geographic information systems software and are based on projections from the Delaware Valley Regional Planning Commission. The impacts of the scenarios on energy use, air emissions, greenhouse gas emissions, water quality, and biological integrity were estimated with very few data, and the effect on the value of generic ecosystem services was assessed. The suitable development scenario was 29% better in terms of energy use and air and greenhouse gas emissions, 2.4% worse on water quality, and 2.6% better with respect to biological integrity. Given its net beneficial results, recommendations for policies to engender suitable development are made, and an outline of an implementation plan is proposed. Thoughts regarding refinements of the present work and the applicability of the methods used here to other watersheds conclude the work.

基于目标距离法的工业化住宅环境影响评价

为了客观衡量住宅产业化对建筑业节能减排和降低环境污染的贡献,同时明确住宅工业化建造模式较传统建造模式在环境影响方面的优势及需要改进的环节,选择具有代表性的工业化住宅和传统住宅作为测评对象,从全寿命周期角度,基于目标距离法,根据北京市“十二五”时期各项规划中制定的与住宅建设相关的节能减排和绿色发展目标,建立了基于北京市环境政策的目标距离法评价模型,对比分析了“十二五”时期规划面积的住宅分别采用工业化建造模式和传统建造模式对实现北京市“十二五”环境影响政策目标的作用,得出了工业化住宅较传统住宅在降低资源消耗、生态破坏和健康损害3个方面的优势.

加强中学生环境保护知识教育在教学中的实践

日趋严重的环境问题已成为世界性的问题,环境污染与人类生存、社会的发展和进步出现了尖锐的矛盾,已引起世界各国政府的高度关注。要解决环境问题,必须从教育入手,特别是在中小学中加强环境教育。怎样对学生进行环境教育呢？本文从三个方面进行了探讨,一是以讲座形式对学生进行环境教育;二是组织学生进行课外活动或参观;三是请有关专家对学生进行专题报告。学生通过这些活动可了解到化学物质对环境污染所造成的严重后果,了解到环境问题是和每个人息息相关的,保护环境是每个人义不容辞的责任,这将使中学化学教育在加强环境保护教育中起到应有的作用。     

Towards guidelines for post‐disaster vulnerability reduction in informal settlements

Although the development community has long recognised that securing land tenure and improving housing design can benefit significantly informal settlement residents, there is little research on these issues in communities exposed to natural disasters and hazards. Informal settlements often are located on land left vacant because of inherent risks, such as floodplains, and there is a long history worldwide of disasters affecting informal settlements. This research tackles the following questions: how can informal settlement vulnerabilities be reduced in a post‐disaster setting?; and what are the key issues to address in post‐disaster reconstruction? The main purpose of the paper is to develop a set of initial guidelines for post‐disaster risk reduction in informal settlements, stressing connections to tenure and housing/community design in the reconstruction process. The paper examines disaster and reconstruction responses in two disaster‐affected regions—Jimani, Dominican Republic, and Vargas State, Venezuela—where informal settlements have been hit particularly hard.     

Measuring disaster recovery: bouncing back or reaching the counterfactual state?

How should one measure the recovery of a locale from a disaster? The measurement is crucial from a public policy and administration standpoint to determine which places should receive disaster assistance, and it affects the performance evaluation of disaster recovery programmes. This paper compares two approaches to measuring recovery: (i) bouncing back to pre‐disaster conditions; and (ii) attaining the counterfactual state. The former centres on returning to normalcy following disaster‐induced losses, whereas the latter focuses on attaining the state, using quasi‐experimental design, which would have existed if the disaster had not occurred. Both are employed here to assess two housing recovery indicators (total new units and their valuations) in Hurricane Katrina‐affected counties (rural and urban). The examination reveals significantly different outcomes for the two approaches: counties have not returned to their pre‐disaster housing conditions, but they do exhibit counterfactual recovery. Moreover, rural counties may not be as vulnerable as assumed in the disaster recovery literature.     

Impediments to recovery in New Orleans' Upper and Lower Ninth Ward: one year after Hurricane Katrina

In the aftermath of Hurricane Katrina, a rapid succession of plans put forward a host of recovery options for the Upper and Lower Ninth Ward in New Orleans. Much of the debate focused on catastrophic damage to residential structures and discussions of the capacity of low-income residents to repair their neighbourhoods. This article examines impediments to the current recovery process of the Upper and Lower Ninth Ward, reporting results of an October 2006 survey of 3,211 plots for structural damage, flood damage and post-storm recovery. By examining recovery one year after Hurricane Katrina, and by doing so in the light of flood and structural damage, it is possible to identify impediments to recovery that may disproportionately affect these neighbourhoods. This paper concludes with a discussion of how pre- and post-disaster inequalities have slowed recovery in the Lower Ninth Ward and of the implications this has for post-disaster recovery planning there and elsewhere.
