Some problems related to an environmental factual database: the case Aeolian project

Factual databanks can make an important contribution to environmental management. They help considerably with the difficult processes of integrating the various scientific languages used, and also with the development of valid methods for interdisciplinary research. In the planning the Aeolian project (a multidisciplinary study of an Archipelago north of Sicily), it was considered useful to include a group of workers on methodology and computer science. The hope is that they will help to facilitate the exchange of data and thus contribute to a better understanding of the various phenomena occurring on the islands. This paper discusses the conceptual working aspects of environmental information, together with those characteristics that render it suitable for inclusion in a modern computer‐based system.     

Local engagements with urban bushland: Moving beyond bounded practice for urban biodiversity management

Management of ecologically significant urban green space is likely to be increasingly governed by biodiversity policy frameworks. These frameworks tend to reproduce bounded thinking and strategies that separate green space from its context and characterise people as a disturbance. Like many green spaces these ecologically significant areas are highly valued by visitors and nearby residents. Green space is important for engagement with nature, social interaction, and for respite from daily life: it is strongly connected to surrounding areas and to the lives of people who live there. The dissonance between bounded management thinking and the role of green space in resident's lives may compromise conservation goals if boundedness remains a central concept in management. For an ecologically significant and heavily used area of bushland in suburban Australia we examine management frameworks and the relationships of visitors to the bushland. We find that visitors value the bushland for its social role and as a valuable remnant of native vegetation where they can experience a variety of associations with flora, fauna, and what they perceive as a relatively intact ‘natural’ landscape. Concepts central to management frameworks such as ‘biodiversity’ were not well understood but were incidental to visitors’ understanding of the bushland as environmentally valuable and as an asset to the area. Current management frameworks fail to acknowledge these contemporary associations and isolate the bushland in time and space. We identify where official management frameworks and visitor associations with the bushland diverge and potentially converge and suggest alternative directions for management.

Sharing environmental data across organisational boundaries: Lessons from the rural Wales terrestrial database project

Despite calls for a more collaborative approach to rural planning and policy making involving land use agencies in the British Isles, there remain few instances of formal inter-agency data exchange and integration to address applied management tasks. The well-rehearsed argument that Geographic Information Systems (GIS) present a technology whereby spatially consistent data from a variety of different sources can be integrated to address environmental problems is challenged by the lack of truly collaborative exercises of this nature. Potential reasons for this are outlined with reference to an early study – the Rural Wales Terrestrial Database (WALTER) project – in which we developed a GIS for a pilot area of Wales within a multi-agency framework. The technical and organisational problems encountered during the course of this project are addressed in relation to attempts at improving accessibility to digital data in the 10 years following the publication of the Chorley Report and in the light of recent technological developments such as the use of Internet-based GIS in collaborative planning. The WALTER project is seen as an important reminder of how a collaborative approach to data handling within a GIS environment can have proven and demonstrable benefits to the agencies concerned given appropriate organisational structures.     

Moving beyond the limits of joined-up government? Meta-governance,quality of relations and addressing the politics of joining-up

Recent research has questioned the ability of Local Strategic Partnerships (LSPs) to secure better coordination and management of regeneration across different branches of the state. In a period of economic recession and a curtailing of regeneration finance, reconsideration is therefore required of how to secure greater horizontal and vertical integration by LSPs in regeneration policy, budgeting and service delivery. To this end, it is suggested that there needs to be i) a deeper analysis of the quality of local relationships between partners; and ii) a greater emphasis on the politics of ‘joining up’. This paper critiques the relative influence of each of these factors. It is illustrated that the ongoing ‘meta-governance’ of LSPs, coupled with a number of horizontal barriers to ‘collaborative governance’, are impinging upon the level of integration being achieved. Further efforts will be required to address such issues, especially tackling a number of barriers identified to the politics of ‘joining up’ at a variety of spatial scales.

Investigating the rationale for adopting an internationally-recognised project management methodology in Ireland: The view of the project manager

As businesses become more dependent on technology, effective project management has been recognised as a necessity, in order to lead and deliver quality software applications on time and within budget. One possible option in software projects is the use of a project management methodology. This exploratory research examines why organisations with an existing project management methodology are transitioning to an internationally-recognised methodology, and why organisations that do not have a project management methodology are implementing an internationally-recognised methodology. Results of five case studies suggest that while an in-house project management methodology can work well within an organisation, the benefits of using an internationally-recognised methodology should be considered. These include: the assurance that the organisation is using what is considered to be best-practice; demand from external customers that a recognised methodology is used; assistance with external recruitment; and the availability of suppliers of the methodology for training and support.
