The aspiration the spatial planning should act as the main coordinating function for the transition to a sustainable society is grounded on the assumption that it is capable of incorporating both a strong evidence base of environmental accounting for policy, coupled with opportunities for open, deliberative decision-making. While there are a number of increasingly sophisticated methods (such as material flow analysis and ecological footprinting) that can be used to longitudinally determine the impact of policy, there are fewer that can provide a robust spatial assessment of sustainability policy. In this paper, we introduce the Spatial Allocation of Material Flow Analysis (SAMFA) model, which uses the concept of socio-economic metabolism to extrapolate the impact of local consumption patterns that may occur as a result of the local spatial planning process at multiple spatial levels. The initial application the SAMFA model is based on County Kildare in the Republic of Ireland, through spatial temporal simulation and visualisation of construction material flows and associated energy use in the housing sector. Thus, while we focus on an Ireland case study, the model is applicable to spatial planning and sustainability research more generally. Through the development and evaluation of alternative scenarios, the model appears to be successful in its prediction of the cumulative resource and energy impacts arising from consumption and development patterns. This leads to some important insights in relation to the differential spatial distribution of disaggregated allocation of material balance and energy use, for example that rural areas have greater resource accumulation (and are therefore in a sense “less sustainable”) than urban areas, confirming that rural housing in Ireland is both more material and energy intensive. This therefore has the potential to identify hotspots of higher material and energy use, which can be addressed through targeted planning initiatives or focussed community engagement. Furthermore, due to the ability of the model to allow manipulation of different policy criteria (increased density, urban conservation etc), it can also act as an effective basis for multi-stakeholder engagement.

This article attempts a broad characterization of environmental education (EE) and education for sustainable development (ESD), and includes a short overview of the history of the field, key debates, the main approaches to ESD and EE, and a look toward the future. However, such a brief account should not be considered to be fully comprehensive, and can only be considered to provide a broad overview of the field from the authors’ perspectives

The mining/quarrying industry is a sector of industry where there are very few Life Cycle Assessment (LCA) tools, and where the role of LCA has been poorly investigated. A key issue is the integration of three inter-dependent life cycles: Project, Asset and Product. Given the unique features of mining LCAs, this Note from the Field presents a common methodology implemented within the Sustainable Aggregates Resource Management (SARMa) Project (www.sarmaproject.eu) in order to boost adoption of LCA in the aggregate industry in South Eastern Europe. The proposed methodology emphasises the importance of resource efficiency and recycling in the context of a Sustainable Supply Mix of aggregates for the construction industry. Through its adoption, aggregate producers, recyclers, and governmental planners would gain confidence with LCA tools and conduct consistent and meaningful life cycle analyses of natural and recycled aggregates. © 2011 Elsevier Ltd.

Sustainable development could provide a critical foil for individual
and especially collective reflection on the normative
direction, ends and means employed by societies, particularly
around the economy, its technology and resource-intensive
orientation and configuration with ecosystems. However,
although sustainable development is a constitutional objective
of the EU, its implementation in strategies and policies reveals
a much narrower meaning. By framing sustainable development
as ecological modernisation on the basis of technoscientific
innovation, and by imagining citizens as entrepreneurs in a
knowledge-based European economy, openings for democratic
experimentation and social innovation are limited and even
forestalled. In addition, the disruptive and transformational
potential of citizenship is stymied. Still, sustainable development
has resonance within citizenship and human rights
discourses that provide important resources for the fashioning
of common understanding. These are valuable supplements to
the repertoire of European citizenship that could help to embed
sustainable development in the social fabric and generate
alternative imaginaries and futures of a sustainable Europe.

A wireless energy harvesting protocol is proposed for a decode-and-forward relay- assisted secondary user (SU) network in a cognitive spectrum sharing paradigm. An expression for the outage probability of the relay-assisted cognitive network is derived subject to the following power constraints: 1) the maximum power that the source and the relay in the SU network can transmit from the harvested energy, 2) the peak interference power from the source and the relay in the SU network at the primary user (PU) network, and 3) the interference power of the PU network at the relay-assisted SU network. The results show that as the energy harvesting conversion efficiency improves, the relay- assisted network with the proposed wireless energy harvesting protocol can operate with outage probabilities below 20% for some practical applications.

Purpose – The purpose of this paper is to explore the role of facilities managers in sustainable practice. It also analyzes the change in facilities management (FM) in terms of sustainability.
Design/methodology/approach – This research adopted a combination of literature review and expert interviews. Empirical data were collected through in-depth interviews with 40 industrial experts in the UK and Ireland.
Findings – The analysis of interview results shows a sustainable movement in the context of FM. Facilities managers play important roles in sustainable practice, including integrating all sustainability considerations, linking strategic level with operational level, incorporating FM knowledge and experience into design, disseminating sustainable knowledge and educating people and encouraging sustainability through innovation.
Research limitations/implications – This research goes beyond the limitations of existing studies that are characterized by a lack of positioning facilities managers in sustainability.
Practical implications – Sustainable delivery represents a direction of FM development. This research describes what facilities managers can do and how they should do for sustainable delivery of FM, based on which improvements are made and benefits are maximized.
Originality/value – This research provides a deeper insight into the FM role in the sustainable agenda. The findings of this research help industrial practitioners and academic researchers to better understand sustainable FM.

In today’s world, supply chains are becoming more complex and more vulnerable due to increased interdependency of multiple threats. This paper investigates the vulnerability sources in context of sustainable supply chain in order to minimize the impact of uncertain events. The capability-based perspective is discussed in this paper to understand the strategies to improve the resilience of the supply chain. Paper argues that organisations must think beyond their boundaries to accumulate or integrate network resources and develop critical collaborative capabilities across the supply chain to successfully encounter future disruptions.

Key Points
International research has long since established a gradient between health and socio-economic status and it is now clear that the social and physical context in which people live can have a negative influence on health.
Recent research has established an adverse effect on the health of people who remained in an area that had become more deprived over time
The mechanisms thought to influence health in declining communities include stress, loss of self-esteem, stigma, powerlessness, a lack of hope and fatalism.
These mechanisms are related to the concept of social capital, a resource produced when people co-operate for mutual benefit
Residents’ key concerns relating to the decline in the community are housing shortages which are perceived to be contributing to the breakdown of the family-based community, along with traffic; pollution; non-resident parking problems; a lack of youth facilities; and the influx of ethnic minorities who are less inclined to become involved with the community
In the Donegall Pass a dual process of outward migration and business development has resulted in a decline in social capital within the community which was particularly evident amongst the younger generations
People living in deprived areas, such as the Donegall Pass, that are adjacent to affluent areas, such as the new apartment developments surrounding the area, can often feel relatively more deprived due to such direct comparisons. Although relative deprivation was evident, peer comparisons with the Donegal Road/Sandy Row community were more commonly expressed
The area can be described as a ‘food desert’ as no affordable fresh grocery supplies are available within walking distance
Residents expressed mixed opinions about the future of the Donegall Pass including a common sense of resignation towards the decline in the core community
Many residents recognise the need for people to work together and gain empowerment in order to work with the authorities (i.e., the Housing Executive and the Council) towards progressive re-development that is in keeping with the aims of the community members, however, equally many were impervious towards these suggestions feeling that previous efforts had gone unrewarded.
