Towards a systematic approach of effect prediction: A handbook as guide and aid for environmental prediction. A review

Environmental impact assessment (EIA) is based on the results of effect prediction. In general, there is much diversity in the expertise in the field of environmental prediction between the different categories of actors involved in EIA. In practice it became obvious in The Netherlands that the accessibility and comprehensibility of existing relevant information was insufficient. For improvement, a series of systematic handbooks on effect prediction, useful for all categories of actors, has been developed in The Netherlands. In this way, the selection of effect prediction methods to be used in concrete circumstances is improved and speeded up for all parties involved in environmental prediction. After a discussion of the purpose of the handbook, the realization and structure of the series are presented. Finally, the use and (potential) benefits of the handbooks for environmental management are indicated.     

The contribution of computer‐based information systems to partnership between public agencies and voluntary environmental groups

This paper considers the contribution of computing to the implementation of a policy of partnership between public environmental agencies and local voluntary groups. The present policy commitment to partnerships of this kind is reviewed. Particular information needs arise when public agencies seek to give co‐ordinated support to the environmental action undertaken by local groups. These stem from the disaggregated nature of the structure and functions of the voluntary sector. Computer‐based information systems are identified as a bridge between the regional organisation of public agencies and the local activities of voluntary groups. A computer system devised to aid the forward planning of public support for voluntary action is described. It is considered that this technique has value as part of a wider strategy of interaction between the public and voluntary sectors.     

Environmental audit: III. Improving the management of environmental information for toxic substances

Environmental programs have been commonly driven by a preoccupation with the collection of data in the mistaken belief thatdata is synonymous withinformation. The distinction between data (that is, the quantified and qualitative attributes of a particular environment) and information (specifically, data processed so as to focus upon a particular environmental problem) will become far more important to environmental managers. They will increasingly manage their information through use of what has become known as information resource management (IRM) and the attendant use of critical success factors methodology. Environmental managers will thereby move away from concerns about data and specific EDP hardware and applications toward managing information as a valuable agency resource. In applying IRM, they will find it helpful to include a number of planning elements and to resolve early a number of issues critical to its successful use.     

‘Natural disasters’ and newspapers: Post-tsunami environmental discourse

In this paper we explore the concept of ‘natural disasters’ as opportunities for influencing public perceptions of the environment through the media. We provide a critical analysis of the discourse in a selection of newspaper articles and identify the way in which various actors have utilised UK national newspaper coverage of the Asian tsunami to promote particular agendas and to legitimise policies and actions. A systematic and iterative sampling approach was developed that allowed us to combine quantitative and qualitative methods to search for articles that contained content directly related to the environmental aspects of the tsunami. Three main themes emerged; coastal ecosystems, the fisheries sector, and redevelopment. The discourse within these areas was markedly different. While the coastal ecosystems discourse was hegemonic in terms of narratives and actor coalitions, the fisheries and redevelopment discourse incorporated a more diverse set of actors and storylines that perhaps reflects the lack of consensus on the best way of achieving sustainable solutions. We also contrast the limited discussion and representation of tsunami-related environmental issues within UK national newspapers with the more detailed discussion within the peer-reviewed literature and the grey literature. We argue that ‘natural disasters’ provide both opportunities and risks for raising awareness of environmental issues, mobilising funding and directing action to environmentally and socially vulnerable areas of the world, and that consequently NGOs, intergovernmental bodies and government departments should be mindful of the long-term consequences of global media attention.     

Heritage as exemplar: a pedagogical role for heritage studies in values education

Studies of heritage at all levels of education can help foster understanding of other peoples and cultures and of the environmental issues facing us all. Used judicially, such studies have a highly positive role to play in educating people everywhere to contribute to making the world a sustainable and just environment for future generations. They provide examples or case studies, in the pedagogical sense used by educationalists, that illustrate many valuable points that are central to a sound values education contributing to ensuring that the public, and hopefully the political elite, are engaged in a push for such a just and sustainable future. Individual examples of heritage sites, and especially of World Heritage properties, contain valuable lessons of great pedagogical value.     

关于《环境土建工程》教学改革的探讨

《环境土建工程》是研究环境工程土建施工方法的一门综合性、实践性很强的学科。它是为环境工程专业高职生开设的一门重要的专业基础课。以往这门课程的教学形式较为传统,不适应当今高职教育形式之处很多。因而,改变单一的课堂教学方式,多种教学手段相结合;改革考核、考试办法,培养学生的学习能力;勤于实践总结,不断发现问题,培养创新能力。     

Notions of environment and environmental management in Akwa Ibom State, Southeastern Nigeria

In the study of environmental degradation, there has not been sufficient attention paid to the perceptions of the local inhabitants. The importance of traditional beliefs and practices has often been overlooked. This paper looks at traditional and Christian beliefs in Akwa Ibom State in South Eastern Nigeria. Interviews, observations and focus group discussions were used to collect the data. The data analysis shows that knowledge and attitudes are somewhat linked to tradition but also influenced by Christian ideas concerning genesis. There are a number of recommendations made.

Where to Go? Strategic Modelling of Access to Emergency Shelters in Mozambique

This paper, through spatial-analysis techniques, examines the accessibility of emergency shelters for vulnerable populations, and outlines the benefits of an extended and permanently established shelter network in central Mozambique. The raster-based modelling approach considers data on land cover, locations of accommodation centres in 2000, settlements and infrastructure. The shelter analysis is a two-step process determining access for vulnerable communities first, followed by a suitability analysis for additional emergency shelter sites. The results indicate the need for both retrofitting existing infrastructure (schools, health posts) to function as shelters during an emergency, and constructing new facilities - at best multi-purpose facilities that can serve as social infrastructure and shelter. Besides assessing the current situation in terms of availability and accessibility of emergency shelters, this paper provides an example of evaluating the effectiveness of humanitarian assistance without conventional mechanisms like food tonnage and number of beneficiaries.
