In recent years, the landscape has become another environmental resource, so it is important to incorporate it into planning actions. However, its broad sense of study has made it difficult to develop methodologies that precisely diagnose the state of the landscape and its management requirements, especially in dynamic spaces like urban areas. In order to develop a method capable of providing information that can be incorporated into environmental assessment and territorial planning tasks so that the needs of the landscape are taken into account in the decision-making stages, an objective methodology is presented based on the study of different parameters (biotic, abiotic and socioeconomic) analyzed in the field and subsequently geoprocessed through Geographic Information Systems according to their influence on the landscape. Through the proposed methodology it is possible to determine the quality, fragility and need of protection of the landscape, as well as to identify the diverse landscape units that form the landscape of a territory. Based on these results, a landscape diagnosis can be drawn up to quantify its overall and partial state, carry out monitoring analyses and make comparisons between different landscape units, so that management measures can be adopted according to the obtained scenarios.

Some strategic environmental assessment (SEA) pilot cases in China strive to integrate environmental issues into the planning from the beginning. One of them is the SEA for development strategy of Tianjin Binhai New Area. The SEA adopted an interactive assessment mode with the decision-making process and predicted the environmental impacts of the development strategy on land resource, water resource, energy, surface water, atmospheric environment, and ecosystem of land area and offshore area. The future development strategy of circular economy and low-carbon economy in Tianjin Binhai New Area was also analyzed. Finally, experience from the SEA case was discussed. The case study shows that support from non-environmental agencies, early integration of SEA process and planning process, interactive assessment mode, and sensible environmental protection strategy facilitate the integration of environment into decision-making.

Environmental assessment has been defined as “a general conceptual and methodological framework for describing and predicting how attributes of places relate to a wide range of cognitive, affective, and behavioral responses” (Craik & Feimer, 1987). A primary purpose for assessing environments is to provide valid and reliable information that has utility in environmental planning, design, and management decision making. Implicit in the assessment activity is the assumption of identifiable relationships of physical environmental factors with descriptive and evaluative assessments, and with predictions of responses to places conceptualized in plans and designs, but not yet built. This chapter addresses the utility of research findings. Three primary questions are posed. Why are some environmental assessment and cognition research findings used successfully in decision making while others are not? What factors contribute to these outcomes? And how important are physical environmental factors in planning, design, and management decision making? The preceding chapters by Rachel Kaplan, Reginald Golledge, and Harry Timmermans provide the background for the following discussion. The first section of this chapter presents a brief review of similarities and differences among the three preceding chapters, with specific attention directed to interpretations or definitions of the concepts of assessment and preference, the use of physical environmental variables in the assessment process, and the roles of laypersons and experts in assessment. Potential uses for and applications of environmental assessment research are described in the second section. This is followed by a discussion of the differences between instrumental and conceptual applications and of factors that have been identified as influencing applications, factors such as communications between researchers and users, responsibilities for problem definition, and the context within which the research is conducted. This chapter concludes with a discussion of the opportunities for and probable limitations on applications of the preceding chapters by R. Kaplan, Golledge, and Timmermans. Four concepts and elements that are addressed in the three chapters have been selected for purposes of structuring a comparison among them. These concepts and elements—assessment, preference, roles of laypersons and experts, and physical environmental factors—are particularly salient to the issue of research applications.

Development and evaluation of alternatives is a key process in the strategic environmental assessment (SEA), which enables improvement of the environment, informed decision-making, greater transparency and better opportunities for public participation. It is also the most challenging part of the assessment, because the alternatives are often avoided or considered to the extent to meet the legal requirements. The absence of alternatives in the assessment process significantly diminishes the contribution of SEA to the environmental protection system. The paper will outline the generally applicable methodology for the development and assessment of alternatives in the SEA process, on the example of the Development Strategy of the City of Solin, which is based on the development of the environmental alternative, which significantly contributes to the development of sustainable strategic solutions.

Experiences from the Finnish Strategic Environmental Assessment (SEA) Act were studied by surveying 35 SEA processes. Integration of plan or programme preparation and assessment, organisation of assessment, public participation and consultation, treatment of alternatives, scoping, impact assessment methods, effectiveness, environmental reporting, follow-up, effects on plan or programme preparation, assessment costs and consistency of the assessment were examined and evaluated. The results suggest that SEA is not yet used properly in decision-making. Several shortcomings characterised assessment practices in public participation, establishment and comparison of alternatives, definition of environmental problems, recognition of significant impacts and readiness to use SEA as a planning tool to integrate environmental considerations into the planning. In consequence, the assessments had only minor effects on the adopted plans and programmes. The most critical challenges in Finnish SEA practise are focusing on the most significant environmental issues and strengthening the links between planning, participation and decision-making.
