Over the last decade, South American countries have been promoting physical integration of the territory in response to regional export-driven industrialisation policies and the global demand for agriculture products, livestock, and energy sources. A prominent example of this is the Initiative for the Integration of Regional Infrastructure in South America (IIRSA), which was launched at the Meeting of South American Presidents in 2000. At the time of writing, 514 infrastructure projects (including roads, pipelines, waterways, dams and telecommunications systems), with an estimated investment of US$69 billion, had been initiated. Importantly, previous similar development processes in the region have caused serious negative environmental and social impacts. Therefore, Strategic Environmental Assessment (SEA) has been mandated to ensure that the social and environmental issues are adequately addressed in the project planning process. This paper identifies the conditions under which: (a) the SEAs of the IIRSA projects have been undertaken, and (b) the Action Plans have been (or will be) implemented. Using case studies, it analyses whether the SEAs that have been carried out for the IIRSA's projects can be considered effective under these conditions. Finally, drawing on the case study findings, potential ways for improving SEA performance and maximising effectiveness in South America are discussed.

Municipal waste management strategies (MWMSs) are local level policy instruments, prepared in an area wide manner all over England, aiming to achieve more sustainable waste management practices. Their focus is on different aspects of the waste management hierarchy, including waste reduction, reuse, recycling/composting and residual waste management. In this paper, a systematic review of MWMS strategic environmental assessments (SEAs), completed by February 2010 is provided. SEA report quality and the extent to which climate change mitigation is considered are evaluated. Whilst there are strengths of current practice, there is also scope for improvement, particularly regarding a more effective consideration of the waste management hierarchy. Furthermore, whilst climate change mitigation is routinely considered as an overall objective, none of the SEAs set related targets, for example regarding carbon emission reduction.

Watersheds are under increasing pressures from the cumulative environmental effects of human actions. Reviews of recent practice suggest that cumulative effects assessment and management (CEAM) has failed to capture the full range of stressors to Canada's watersheds. Indeed, the limitations to CEAM have been well documented; yet, there has been limited constructive evaluation to help explain why CEAM has failed to advance. In this paper we examine the underlying challenges to the assessment and management of cumulative effects in a watershed context. Based on lessons emerging from the South Saskatchewan watershed, Canada, challenges to CEAM in watersheds include stakeholder understanding and interpretation of cumulative effects; limitations in the scale of current EA practices in watersheds; data challenges; the lack of established thresholds for watershed effects; and lack of clarity regarding watershed science and regulatory capacity. The merits of a watershed-based approach to CEAM to help address these challenges to practice are explored.

In the urban context the quest to enhance economic growth and social well-being is challenged by the need to protect and manage natural resources. In order to promote sustainable urban planning, sustainability objectives are commonly embedded into planning policies, and the associated indicators used to evaluate planning interventions and monitor implementation of such objectives. The applicability of indicators is commonly tied in to their ability to address context-specific issues and monitor progress towards definite goals set at the local level. This paper presents the findings of a participative methodology applied in five European cities to develop a set of sustainability indicators with the aim of optimising their applicability for assessing planning alternatives affecting urban metabolism (i.e. the exchange of materials and energy within cities). The results indicate that engagement of researchers and practitioners through Communities of Practice (CoP) helped bridge the gap between science and practice, and facilitated the selection of consistent and meaningful indicators to be used as a tool for decision-making. However, the results also revealed that planning priorities can significantly shape the extent and scope of sustainability indicators, and that a CoP approach may not always be sufficient to guarantee continuity of collaboration.

Many scholars describe a trend towards stakeholder involvement. Also in Dutch water management, this is expected to generate more support and better-informed information for decision-making. An approach or methodology for the combined involvement of stakeholder and expert inputs in decision-making, however, is lacking (Rinaudo and Garin, 2005; Petts and Brooks, 2006; Leach, 2006; Sabatier et al., 2005; Scholz and Stiftel, 2005). In this article we focus on methodological aspects of an integral stakeholder approach in relation to its expected contribution to decision-making. We describe and analyse an approach of co-valuation for spatial issues, including multiple actors involved. Experiences with this approach in a case study on Dutch spatial water management reconfirm that existing assessment methodology does not provide for the involvement of stakeholder inputs and focuses on expert-based information. An interactive approach of (existing) (e)valuation (methods) may involve these various knowledge bases in assessment.

As they make decisions about collective goods, policy makers strive to apply objective standards to complex environmental issues. This challenge requires the use of analytic methods that can include the multiple dimensions of such complex problems. Life-cycle analysis is a physical model that is widely recognised for its utility in investigating and improving the environmental impacts across the supply chain. However, models such as environmental life-cycle analysis are insufficient by themselves for policy-making because they do not formally include the interdependent, dynamic, often socioeconomic choices that influence supply-chain firms, and thus affect environmental outcomes. We show that game theory can be applied to improve environmental policy-making for the end-of-cycle stages of supply chains by strategically considering environmental and economic incentives. These incentives are often dependant on previous life-cycle stages while affecting future life-cycle stages. We demonstrate these techniques with a case study of open-loop (out-of-network) pallet systems for shipping consumer goods while also discussing the remaining challenges.

This paper argues that the new generation of community based natural resources management (CBNRM) should involve the arts, and particularly the community arts, to better enable success in engaging communities in land rehabilitation and ecological sustainability. The paper is based on insights gained from a five-year research project which examined the role of the arts in affecting environmental behaviour. About 200 informant interviews were undertaken, and eight case studies were analysed to provide qualitative and quantitative data. The case studies presented in this paper show that a culture of landcare is gradually evolving and there is a general overlap, and perhaps even convergence, between the community arts and community environmental initiatives such as Landcare. There are now many community arts events that have an environmental focus, and increasingly CBNRM is using the arts to encourage greater community involvement in the issues and to provide an artistic voice of those involved in CBNRM.
