In order to find negotiable solutions for spatial planning and landscape development, scenario analysis would profit from knowledge about the trade-offs people make in their policy objectives given a certain landscape scenario. To facilitate the development of normative landscape scenarios, the output of a land-use decision model was visualized in 3D, establishing a relationship between policy influence factors (as model drivers) and the 3D visualizations. A survey tool was developed for eliciting the preferences for these 3D visualizations and the respective policy measures. In this contribution, we present the survey tool tested in a case study from a pre-Alpine area in central Switzerland. Results show participants' preferences for extensive agricultural land use and limitation of urban sprawl. The trade-off analysis shows how participants compare and choose among different policy objectives to reach a possible solution given their choice of a future landscape. The trade-off pathway most often observed reinforces the chosen visualization in terms of policy measures. In the discussion, we consider the advantages and disadvantages of this survey tool and conclude that it is an effective way to support the development of normative landscape scenarios in participatory planning processes.

Impact on the perceived landscape quality through renewable energy infrastructure. A discrete choice experiment in the context of the Swiss energy transition

B. Salak, F. Kienast, R. Olschewski, R. Spielhofer, U. Wissen Hayek, A. Gret-Regamey, M. Hunziker

Summary: This study examines the impact of different mixes of renewable energy infrastructure (wind, photovoltaic, power lines) on people's preferences for various landscape types. The results show that landscapes dominated by settlements or intensive agricultural use and landscapes in mountain tourist areas are preferably selected for renewable energy infrastructure developments, while near natural, mid/high-elevation landscapes in the Alps are clearly rejected. Additionally, scenarios including overhead power lines perform consistently lower than scenarios without power lines. Overall, the study highlights the need for increased awareness and implementation of massive renewable energy infrastructure to achieve a sustainable energy transition.

Greater place attachment to urban parks enhances relaxation: Examining affective and cognitive responses of locals and bi-cultural migrants to virtual park visits

Mahsa Bazrafshan, Reto Spielhofer, Ulrike Wissen Hayek, Felix Kienast, Adrienne Gret-Regamey

Summary: This study aims to assess the relationship between place attachment and well-being in urban parks in a mobility and migratory context through virtual park visits. The experimental study involved bi-cultural residents and locals who experienced two comparable urban parks in an audio-visual laboratory. Statistical analyses show that place attachment and familiarity with the cultural background of a park have a significant influence on affective responses, particularly relaxation. Additionally, there is experimental evidence that measurable place attachment has developed among bi-cultural migrants in their new place of residence. The results align well with theories of place attachment presented in the article.

The 3P's of place-making: Measuring place-making through the latent components of person, procedures and place

Michal Switalski, Marcelo Galleguillos Torres, Adrienne Gret-Regamey

Summary: Place-making refers to the process in which meaningful places are created through interactions between people and their environments. This study presents an initial attempt to describe and measure place-making using latent variable modelling. The results show that neighbourhood place-making can be characterized by three factors: person, procedures, and place. The study also identifies the influence of other factors, such as social cohesion and place attachment, on place-making scores. The implications of the place-making framework for deliberate place change in rapidly urbanizing contexts are discussed.

How previous experiences shape actors & apos; current perspectives in integrated natural resource management

Raphael Gaus, Olivier Ejderyan, Adrienne Gret-Regamey, William D. Leach, Matthias Buchecker

Summary: Previous experiences play a crucial role in shaping current perspectives in integrated natural resource management. The quantity and quality of past experiences in water management, participation, and politics are differently linked to the information and beliefs of current perspectives. More experienced actors have broader perspectives, while less experienced actors are particularly interested in approaches to water management. Previous experiences should be considered when designing participatory processes in integrated natural resource management, and a diverse composition of actors with different types of experiences and perspectives can be valuable.

Evaluation of sense of safety and privacy in parks in relation to the topography, the presence of dense vegetation and other people in the area

Aleksandra Lis, Karolina Zalewska, Pawel Iwankowski, Katarzyna Betkier, Paulina Bilska, Viktoriia Dudar, Aleksandra L. Lagiewka

Summary: Appleton's prospect-refuge theory suggests that the presence of dense vegetation, topography, and people in a park can influence the safety and privacy felt by visitors in different ways. This study aimed to understand the relationship between observation point height, vegetation location, presence of other people, and perceived privacy and safety. The results showed that flat or lower ground without the presence of others was considered the safest, while landscapes higher up with dense vegetation and no other people were rated highest in terms of privacy. The findings have practical implications in terms of providing privacy without compromising safety.

Policy instruments for green infrastructure

Astrid Zabel, Mara-Magdalena Hausler

Summary: Developing a green infrastructure is an important environmental policy goal in many countries around the world. Different countries have different requirements on the spatial allocation of conservation sites for green infrastructure. Price-type and procedural instruments are commonly used, but the utilization of incentive mechanisms that internalize the benefit of clustering is relatively low. There is a need for more studies on incentive mechanisms and green infrastructure policies in the global South.

Physiological and psychological responses to transitions between urban built and natural environments using the cave automated virtual environment

Di Chen, Jie Yin, Chia-Pin Yu, Shengjing Sun, Charlotte Gabel, John D. Spengler

Summary: Observational and experimental studies have shown that exposure to greenness is beneficial for long-term health and well-being. However, more evidence is needed regarding the short-term health impacts of nearby nature in urban areas. This study used immersive virtual reality technology to investigate how transitions between built and natural environments affect urban residents. Results showed that transitioning from built to natural environments led to reductions in negative mood and transient anxiety, while transitions from natural to built environments had the opposite effect. Additionally, participants showed more emotional responses to nature through physiological measures. The study also highlighted the influence of contextual factors, such as physical health conditions, stress levels, experience with nature, and growth environments, on stress recovery. Overall, this study provides empirical evidence supporting the promotion of nearby nature in urban built environments.
