Landscape Aesthetics Capacity as a Cultural Ecosystem Service (2019) Landscape Planning with Ecosystem Services. Landscape Series, vol 24. Springer, Dordrecht 24 , S. 221-252.
DOI: 10.1007/978-94-024-1681-7_15
This chapter explores established theoretical and empirical work to identify possible indicators to represent landscape aesthetics capacity (LAC) in landscape planning. Throughout this chapter we argue that visual concepts from landscape perception/preferences studies (formed either on an individual or collective basis), together with experiences from implementing Landscape Character Assessments (LCA) throughout Europe, might help in developing frameworks for the assessment of Cultural Ecosystem Services (CES). When compared to provisioning or maintenance/regulating ecosystem services (ES), frameworks for the application of CES are lagging in development. Landscape aesthetics capacity is conceptualized here as delivered ES, which are central to the everyday life of people. The concepts we focus on are derived from landscape preference studies. The empirical cases explored are from LCAs in the United Kingdom (UK) and Hungary, from the Landscape Preferences Spatial Framework in Portugal, and from a formal method for mapping and assessing the visual landscape in Germany. There is also a brief overview of current methodological approaches and suggested indicators regarding the utilization of CES. Finally, the chapter emphasises the ways in which landscape aesthetics capacities can be incorporated into planning, by selecting a group of robust indicators (based on theory as well as on our case studies) that could be applied in different European countries.

An Interactive Landscape Planning Process for Sustaining Flood Regulation in the Ci Kapundung Upper Water Catchment Area , Bandung Basin , Indonesia. (2019)
DOI: 10.14627/537663004
Simulations and modelling are often used in many studies to assess and visualise the effects of landscape changes on environment. However, only a few studies have been conducted to assess landscape interventions to sustain ecosystem services, including hydrological processes. This paper presents an iterative and interactive process to generate landscape planning for the Ci Kapundung upper water catchment area, Bandung Basin, Indonesia, based on two development scenarios. The land change model was coupled with a hydrological model to assess the influence of land cover changes on flood risk in Bandung Basin. The result shows that the overland flow at three observation points is affected by the land cover, topography, and soil properties. Outputs from the iterative hydrologic sim- ulations suggested that conifers could be planted in the proposed river buffers in the case study area to reduce the volume of runoff flowing to the Ci Kapundung River.

Fracking (2019) Technical Information Note. Landscape Institute: London 04/2019 .
Hydraulic fracturing (also called fracking or sometimes fraccing; in this Technical Note the terms are used synonymously) is a way of extracting gas (and sometimes oil) from shale rock. Both terms refer to the injection of water, sand and chemicals into the rock at high pressure to break the shale and release the gas, a process sometimes called well stimulation.

Road Safety from Cyclist’s Perspective Magdalena (2019) REAL CORP 2019 , S. 597-604.
Road safety is an essential design requirement in planning processes of cycling infrastructure. An evaluation criterion for safety are accident statistics, but this criterion lacks reliability with regard to cycling accidents because many accidents are not documented. In addition, an exclusive view of accident statistics only is inadequate because road safety also includes aspects such as objective as well as subjective safety of cyclists. In order to consider the cyclist’s perspective in the planning of cycling facilities, an exploratory study, based on the concept of the Urban Emotions Inititative, was carried out in Augsburg and presented in this contribution. The aim of the study was to investigate the influence of cycling infrastructure on the cyclist's stress and the perception of safety. As a result, 1040 stress situations of 26 cyclists were measured over a distance of 5.0 km using biostatistical measurement technology. 347 stress situations refer directly to road infrastructure and perceived safety. In addition, data from traffic and urban planning as well as other self-collected data regarding objective traffic safety were used to assess the cycling infrastructure. The analysis of the study shows that the objective analysis of road infrastructure and the subjective sense of safety of the cyclists are in many cases corresponding. An interesting result was that stress situations can differ in the same types of cycling facilities. A conclusion for stress and perception of safety is that constructive detail is more detached from stress triggers than the type of cycling facilities in general. An important issue is surface design. Bumps, damaged pavement and tram rails are often stressful, especially in combination with other road users. There are no clear differences in the frequency of conflicts between car drivers, pedestrians and cyclists. The number of stressful situations, in which a pedestrian was involved, was slightly predominant. Stress situations were caused through inappropriate use of cycle lanes, problems with orientation, confusing paths and a lack of acceptance of some types of cycle facilities. Base for this contribution is the bachelor thesis Road Safety from Cyclists´ Perspective.

Assessment of Aesthetic Preferences in Relation to Vegetation-Created Enclosure in Chinese Urban Parks: A Case Study of Shenzhen Litchi Park (2019) Sustainability 11 (6), S. 1-16.
DOI: 10.3390/su11061809
Building on the mystery/complexity/legibility/coherence model of Kaplan and Kaplan (1989) and up-to-date landscape visualization techniques, this paper presents a case study analyzing people’s aesthetic preferences for scenes with varying levels of enclosure created through vegetation. Participants were asked to view 48 computer-generated urban park scenes with different levels of enclosure and to rate them for three aesthetic preference factors: coherence, complexity, and legibility. The results are as follows: (1) If the visual and/or physical setting is enclosed, participants will give lower ratings for legibility than in open scenes. (2) Physically open scenes are rated as more coherent than physically enclosed scenes. (3) Participants rate complexity for physically enclosed scenes lower than for physically open scenes. It is concluded that enclosure as a predictor variable for landscape preference has a practical significance for future urban landscape research and designs.

Future Development Scenarios for Adaptation to Climate Change in the Ci Kapundung Upper Water Catchment Area , Bandung Basin , Indonesia (2018) JoDLA − Journal of Digital Landscape Architecture 2018 (3), S. 23-33.
DOI: 10.14627/537642003
Landscape change in the Ci Kapundung upper water catchment area over recent decades has increased the volume of rainfall runoff, increasing the incidence of flooding in the Bandung Basin. At the same time, climate change affects rainfall variability in Indonesia, causing higher frequencies of extreme rainfall and drought in almost all regions of the country. This study develops and assesses four scenarios for the future spatial plan in the catchment area, which is part of a research project on flood risk in the Bandung Basin. The scenarios were created based on recent land use changes within the area, current spatial policies, ecological design principles, and the geodesign framework. All scenarios were simulated using Land Change Modeler (LCM), which applies a combined cellular automata and Mar- kov model (CA-Markov), and a multilayer perceptron (MLP) neural network, to project future land- scape forms for 2030. In this simulation, the results were assessed to see the variations of land cover composition. CA-Markov models have been widely used to predict urban growth. Modeling applica- tions for forest cover change simulation have rarely been explored. Results from LCM show that there is no significant difference in the percentages of developed areas, mixed plant communities, and coni- fers in 2030 in all scenarios. However, the spatial arrangement of land cover varies with each scenario. In the first scenario, for example, the disperse settlement pattern is projected to occur in the watershed in 2030, including in the areas with steep slopes and near the rivers, whereas in other scenarios, specific areas are restricted to be built. The study suggests that further analysis of hydrological impacts of each scenario is needed to ascertain which scenario can effectively reduce flood risk.

Geodesigning Climate Change Adaptation on a Regional Level through Shelterbelt Provision in the Jingjinji Area (2017) JoDLA − Journal of Digital Landscape Architecture 2017 (2), S. 125-135.
DOI: 10.14627/537629013
More than 109 million people already live in the Jingjinji Area, the greater metropolitan area around Bejing and the number of inhabitants as well as land take for new housing is increasing dramat- ically. At the same time, the region is under threat from climate change, especially through desertifica- tion. The government has identified shelterbelt forests as appropriate adaptation measures. However, the designation of new shelterbelts has to be integrated in the wider regional planning process for the Jingjinji Area and this pilot study explores the potential of the geodesign framework and the Ge- odesignhub online platform for this monumental task. Four development scenarios and two evaluation models with constraint maps were set up a prior. Then, we conducted two workshops, partly remotely, with 12 participating landscape architecture PG and PhD students across the world. In terms of the planning task, the workshop resulted in a synthesis map of how housing, industry and commerce, the 2020 Winter Olympics, transport infrastructure, green infrastructure and particularly shelterbelts can be located in the Jingjinji area. Parallel, a process evaluation was conducted resulting in valuable feed- back regarding the strengths and limitations of the geodesign framework and online tools for this case study.

The Effect of Topographic Correction on SPOT6 Land Cover Classification in Water Catchment Areas in Bandung Basin , Indonesia (2017) GISRUK 2017 2017 .
Currently, there is no generally accepted topographic correction method to be applied in different landscape contexts. This study derived land cover maps in Ci Kapundung and Ci Sangkuy upper water catchment areas, which are located in a rugged terrain in mountainous areas in Bandung Basin, Indonesia, using object-based classification of satellite images. Under these conditions, a modified sun-canopy-sensor correction (SCS+C) was chosen as topographic correction method. Its performance was evaluated based on the Overall Accuracy (OA). Result shows that the correction method could improve the accuracies to 77% and 87.58% for the first and second case studies respectively.
