To achieve a sustainable development, impacts onbiodiversity of urbanisation, infrastructure, land use changesand other developments must be considered on a landscape andregional scale. Landscape ecology can provide a conceptualframework for the assessment of consequences of long-termdevelopment processes like urbanisation on biodiversity on alandscape scale, and for evaluating the impacts of alternativeplanning scenarios. The aim of this study was to explore theeffects of habitat quality, quantity and connectivity on forestbird diversity in an urban-rural gradient. The purpose of theanalyses was to develop knowledge and methods for integratingbiodiversity issues in planning and assessments in anurbanising environment, on landscape and regional scales. The study area was situated in and around Stockholm, thecapital of Sweden, covering the city centre, suburbs andperi-urban areas. Data on breeding forest birds were collectedthrough bird censuses in an urban-suburban gradient. In orderto embrace also the peri-urban areas for a more completeurban-rural gradient, data on two fragmentation-sensitiveforest grouse species were obtained through a questionnaire tohunters in the whole study area. Response variables in theanalyses were forest bird species richness and diversity,relative species richness and occurrence of single sensitivespecies like selected sedentary forest birds, including theforest grouse species, and red list species. Habitat quality,quantity and connectivity were analysed using available data onabiotic conditions, including urban disturbances, andvegetation in geographical information systems. In addition, afield study on vegetation structure and composition wasperformed in a subset of the smaller sample sites.Relationships between the response variables and habitatquality, quantity and connectivity were explored usingstatistical methods like multivariate statistics and regressionmodelling. Further, for some models, spatial dependencies werequantified and accounted for. When habitat models wereretrieved, they were used for spatial predictions of habitatsuitability. They were also applied on future planningscenarios in order to predict and assess the impacts onsensitive species. In the urban-rural gradient, the foreststructure and composition changed, so that in more urban areas,coniferous forest on rich soils, wet forests and wetlandsbecame less abundant and more scattered. Sensitive birdspecies, tied to these habitat types, were shown to besensitive to habitat fragmentation caused by urbanisation.Large, well-connected habitat patches and aggregations ofsuitable habitat in the landscape had a higher probability ofoccupancy when compared to other patches. For the forest grousespecies, effects of car traffic added to the explanation oftheir distribution. By contrast, deciduous forest was stillquite common in predominantly urban areas, due to both latechanges in land use and a history of human preferences. Certainred listed bird species tied to deciduous forest did not seemto be affected by isolation, and also occurred in suitablehabitats in some highly urbanised areas. Furthermore, relativespecies richness in the urban-suburban gradient was related tomulti-layered deciduous forest habitats with a large amount ofdead wood. Such habitats were associated with natural shorelineand with old pastures and parks. From the derived statisticalmodels, describing the relationships between sensitive speciesand environmental variables, predictive habitat maps could becreated for the present situation and for planning scenarios.The predictions of the impacts on habitats of sensitive speciesmade it possible to quantify, integrate and visualise theeffects of urbanisation scenarios on aspects of biodiversity ona landscape scale.

Strategic environmental assessment (SEA) is used as a policy tool in the management of offshore oil and gas. As offshore oil and gas exploration continues to advance further into Arctic regions, questions of how SEA fits into petroleum policy frameworks, its process, and its effectiveness arise. This thesis adopts a historical institutionalist approach to explain SEA in Norway’s offshore oil and gas sector, discussing lessons to be learned from the Norwegian case, as well as the applicability of SEA in similar Arctic governance regimes. The thesis identifies three main lessons: First, Norway’s management of Arctic offshore hydrocarbon resources is a reflection of its distinct path of political development, particularly its emphasis on reaching consensus on sensitive political issues. Second, from the onset, Norway had the economic and political means to develop the institutional capacity and international experience required to manage an international offshore oil and gas operation. Third, the combination of these factors allowed Norway to adopt an incremental approach towards the advancement of its petroleum development, enabling decision-makers to adopt the principles of strategic environmental assessment into the policies that govern Norway’s offshore resources.

The thesis addresses the introduction of a supra-national instrument; a European directive on Strategic Environmental Assessment (SEA) into national contexts of land-use planning in three countries; Sweden, Iceland and England. The directive ”On the assessment of the effects of certain plans and programmes on the environment” was agreed upon by the European Commission on the 21st of June 2001 and was to be transposed to national legislation by 21st of June 2004. The introduction of these requirements meant that the countries needed to make legal adjustments and implement it at the different levels of planning. Many EU member countries, including those studied in the thesis, had some experience of environmental assessment of plans and programmes prior to the introduction of the SEA directive. SEA has as a concept and a tool in planning in national and international debate on Environmental Assessment and planning for the last two decades. Hence, the SEA directive was introduced to an existing context of environmental assessment in planning and the preparation of the directive has drawn on substantial conceptual development and practical experience of strategic environmental assessment in various forms. The aim of this research is to shed a light on the transposition of the SEA directive into a national legal framework and how the introduction relates to the countries’ planning contexts and previous application of SEA-like instruments. In the thesis an overview is given of the way the directive is transposed to the national legal system of the three countries and the existing planning framework is described. The results from the national reviews are analysed in relation to the contents of the directive and the international and Nordic academic debate regarding the purpose and role of SEA, related to the characteristics of the planning system. The research shows differences in the legal and planning contexts to which the SEA requirements have been introduced in the three countries. Despite of those, the legal requirements follow closely the contents of the directive. However, the expectations towards the directive expressed by national officials and politicians, the recommendations in the way the legal SEA requirements shall be implemented, differ between the countries as well as references to other processes; land-use planning and the practices of Environmental Impact Assessment and Sustainability Appraisal. The thesis is the result of a project within the interdisciplinary research programme MiSt, “Tools for environmental assessment in strategic decision making” at BTH funded by the Swedish Environmental Protection Agency. The project has been carried out at Nordregio, the Nordic Centre for Spatial Development, Stockholm. / MiSt Report 6

This thesis explores how planning for sustainable development can be enhanced in Australia with a particular focus on strategic plans. Today, the concept of sustainable development has not been fully operationalised into plans; market and political forces still play a predominant role in planning practice. Nevertheless, some authors believe that the concept of sustainable development has reinvigorated planning. For example, there is an extensive literature on this topic within planning theory, although in practice, sustainable development has been difficult to implement. This thesis after acknowledging the relevance of economy and politics, provides an alternative approach to operationalise sustainable development in plans through a technical perspective. This perspective is based on the examination, from literature, of several techniques which deal with sustainable development. The central idea is that these techniques can be embraced under one concept,

In Canada, interest in regional strategic environmental assessment as a framework for assessing cumulative environmental effects is growing. Strategic environmental assessment, and in particular regional strategic environmental assessment, is generally regarded as the preferred assessment framework within which to address cumulative effects due to its broad scale of assessment and its focus on influencing future development. However, very little research has been done to confront the challenges, either conceptually or methodologically, in operationalizing strategic environmental assessment at a regional scale and in assessing cumulative environmental effects in this regional and strategic context. This dissertation advances work in this area by defining a conceptual framework and generic methodology for regional strategic environmental assessment that deliberately integrates cumulative effects considerations.<p> The research methodology includes a literature review, framework and case reviews, and three sets of interviews with Canadian and international practitioners, academics, and administrators knowledgeable on strategic environmental assessment and cumulative effects assessment issues. The research results are reported in four manuscripts. The first manuscript presents a typology of current approaches to regional cumulative effects assessment. The second manuscript reviews lessons from recent attempts at regional-scale, strategically-focused environmental analysis in Canada that include an impact assessment component and explicit attention to cumulative environmental effects. The third manuscript presents a structured framework for regional strategic environmental assessment in Canada, and the fourth manuscript discusses conceptual and methodological challenges that accompany the integration of strategic environmental assessment and cumulative effects assessment.<p> Significant findings include that cumulative effects assessment does indeed represent a significant conceptual and methodological challenge in a strategic assessment context and that cumulative effects assessment in this context requires more than simply adding up direct effects. Further, this research indicates that the seminal contribution of regional strategic environmental assessment is to determine the pace and nature of future development in a region, including significant regional environmental thresholds, targets, and limits; and to inform decision makers of the broader, the slower-moving, the farther-reaching, and perhaps the more insidious currents of environmental change. Moving forward, there is a need to further develop and demonstrate approaches to cumulative effects assessment in a strategic context, develop a supportive legislative and regulatory framework for regional strategic environmental assessment in Canada, and define the unique contribution of regional strategic assessment in relation to regional planning and management.

Strategic environmental assessment (SEA) has been practiced in Canada since the early 1970s. However, its added value to policies plans and programs (PPPs) has yet to be fully realized. Consequently, many planners and decision makers are skeptical about the benefits of SEA, in part because of the lack of cases to indicate its added value to PPP development or downstream assessment. Much of the SEA evaluation research to date has focused on the procedural requirements and process elements of SEA rather than on its outputs and outcomes. The overall purpose of this research was to examine the efficacy of SEA and “SEA like” processes in Canada. The research examined how SEA practices have influenced PPP development, decision-making and subsequent actions in Canada. Data were collected using SEA efficacy evaluation criteria through semi-structured interviews with experts and non-experts across Canada based on their experience with and perspectives on the ‘impact’ of SEA. There has not been any study into the efficacy of SEA that is based on its added value. Most studies so far have focused on SEA inputs and process rather than outputs and broader outcomes in Canada. This research contributed not only to SEA efficacy studies, but also to improved SEA application and value added for PPP development in Canada.

Strategic Environmental Assessment (SEA) has a prominent position in the ongoing search for instruments that can help governments and other organizations to pursue the goal of sustainability. SEA is presented here as a decision-making supportive approach that is meant to improve strategic initiatives, rather than just analysing them. As an approach to planning (as opposed to a mechanical technical instrument that is done on the side and ‘might’ inform the big decisions), SEA has been promoted as a promising instrument expected to be able to provide better informed, more credible and more broadly beneficial strategic initiatives, as well as more timely and clearer guidance for subsequent undertakings. As such, by adjusting and improving planning, governance, and decision-making processes, SEA has a major role in contributing to sustainability. One of the many different planning and decision-making contexts in which SEA can be used is growth-related planning – the object of interest of this research. Planning in a growth context is typically driven by a mix of biophysical, social and economic concerns, and is unavoidably complex, with many independent agents interacting with each other in many ways, all of this involving the full range of intersecting sustainability issues. In this research I explore the concept of sustainability as an overall planning goal, as it relates to a particular approach to planning, i.e., strategic environmental assessment. In addition, this research acknowledges the importance and need to address the context in which SEA applications occur, and therefore, it highlights the need to specify the application for particular areas. This research was guided by an interest in improving understanding of how SEA can help to contribute to sustainability through planning/EA processes and activities, especially in the context of growth-related planning. Above all, this research addressed how SEA best practices can be used to improve regional planning and decision making, including its link to the project level, and how regional planning experience can help illuminate possible means of strengthening SEA practice. As such, this research presents how a sustainability-based SEA approach could contribute to growth-related planning in a rapid growth setting, using York Region, Ontario as the empirical case study. While York Region was not using the SEA nametag, some essential characteristics of SEA were found in a few planning initiatives, in accordance with what some scholars have called a SEA-type approach, i.e., an approach that does not meet formal specifications or definitions of SEA, but which has some of the SEA characteristics or components. This research presents three main scholarly contributions. First, it develops a SEA best practice framework based on the international literature and, as a result, it provides SEA practitioners with a useful generic framework that they can use as guidance and a starting point for SEA studies. In addition, this research brings to light the importance of paying attention to contextual issues in order to make successful use of SEA best practice frameworks. The context of application will always be unique, so the particularities of the case will still need to be carefully considered and incorporated, so that application can be customized to the particular case. Second, this research further develops the discussion about what SEA can achieve, or more specifically, how SEA can help to contribute to sustainability. As such, this research contributes to the discussion about how SEA can help planning and decision-making approaches through a more in depth look at three main components of SEA: sustainability-centred decision making, tiering and communication. The third contribution relates to how SEA adoption becomes a priority or how governments become interested enough in SEA application to actually give it a shot. The concept of a policy window was borrowed from the policy sciences field to provide the framework of analysis for this part of the research, and shows how problem, policy and political streams converged to provide the necessary conditions for the adoption of an SEA-type approach in York Region. In sum, the results of this research suggest that SEA has potential to play an important role in planning and decision making, with particular attention to growth-related planning. In this context, SEA can contribute to planning and decision making that is more integrated, farsighted, open, efficient, credible and defensible, and ultimately brings desirable and durable benefits. Moreover, by providing clearer guidance to the subsequent undertaking, SEA has potential to serve as a bridge to the planning of project-level undertakings.

Meaningful public engagement is a challenging, but promising, feature of strategic environmental assessment (SEA) in developing countries such as Kenya. This research examined completed Kenyan SEA and compared procedures to standard practice, with particular emphasis on public participation. Two selected SEA case studies explored the extent of participation, learning outcomes of participation, and whether the learning outcomes lead to social action for sustainability at the community level. Document reviews, participant observation, a focus group, and semi-structured interviews with environmental practitioners, government officials, and community members provided data for the thesis. The study revealed that public participation is variable amongst the completed SEAs and shows that the ideal conditions for learning in public participation were not completely fulfilled, resulting in a greater abundance of instrumental than communicative or transformative learning outcomes. Nonetheless, individual and social actions that contribute to sustainability have been taken based on the learning outcomes.
