Improved Variable Scale Optimisation Algorithm in Water Saving Landscape Design and Its Application

Abstract With the acceleration of urbanisation, the problem of water resource shortage is becoming increasingly serious. Currently, the water use situation in Chinese cities is severe and the contradiction between the supply and demand of water resources is prominent, which has become one of the main factors restricting sustainable development of cities. Traditional research on water-saving landscape design focuses mainly on the analysis of the efficiency of water resource utilisation within a single area or city. The scope of the research is limited and the research methods are individual, which cannot fully meet the current needs of sustainable urban water-saving landscape design. The improved variable scale optimisation algorithm has become an indispensable tool in modern landscape design and would play a more important role in landscape design and ecological environment protection in the future. In response to the shortcomings of traditional variable-scale optimisation algorithms in solving the optimisation problem of water-saving landscape design for ecological sustainable development, this article would use an improved variable-scale optimisation algorithm to study the water-saving landscape design for ecological sustainable development in Community X, City B, Province A. The research results indicated that there were three experts who rated the effect of the water saving landscape design of the first group of designers as good or above, accounting for 37.5 %. The number of people who rated the effectiveness of water-saving landscape design in the second group as good or higher was 8, representing 100 %. The improved variable-scale optimisation algorithm could effectively improve the application of water-saving landscape design in ecological sustainable development.

Keeping It Loose: Promoting Physical Literacy in Schoolyards Through Landscape Design and Movement Provocations

In this essay, Lisa Sandlos and Rennie Tang investigate the potential for movement to play a more significant role in schoolyard design processes to enhance the physical literacy of middle school youth. This research responds to a need for prioritizing physical literacy for historically marginalized youth whose movement needs are often different from what is currently provided by athletics- focused school programming. The study draws on urban design theory, an ecological approach to psychology, movement/ dance studies research theory, and creativity studies to explore landscape design strategies that have the potential to cultivate a more robust culture of physical literacy in schoolyards.

Examining the importance of neighborhood natural, and built environment factors in predicting older adults' mental well-being: An XGBoost-SHAP approach

BackgroundPrevious studies have shown that urban neighborhood environmental factors significantly influence the health outcomes of urban older adults. However, most cross-sectional studies exploring the health effects of these factors have failed to quantify the relative importance of each factor. MethodsWe use XGBoost machine learning techniques and SHAPley Additive Interpretation (SHAP) to rank the importance of urban neighborhood environmental factors in shaping the mental health of urban older adults. To address self-selection bias in housing choice, we distinguish older adults living in private housing from those living in public as residents in private housing have more freedom to choose where to live. ResultsThe results show that both natural and built environmental factors in urban neighborhoods are important predictors of mental well-being scores. Five natural environmental factors (blue space, perceived greenery quantity, NDVI, street view greenness, aesthetic quality) and three built environmental factors (physical activity facilities quality, physical activity facilities quantity, neighborhood disorder) had considerable predictive power for mental well-being scores in two groups. Among them, blue space, perceived greenery quantity and street view greenness quantity became less important after controlling for self-selection bias, possibly because of the unequal distribution of quantity and quality, and the performance of neighborhood disorder, aesthetic quality and physical activity facilities quality was more sensitive in public housing. ConclusionsThese results highlight the nuanced and differential effects of neighborhood environmental exposures on mental well-being outcomes, depending on housing preferences. The results of this study can provide support for decision makers in urban planning, landscape design and environmental management in order to improve the mental well-being status of urban older adults.

Accessibility to Urban Parks by disablers: A Case Study on a Main Park in Erbil

Quite a large number of Iraqi – Iran war victims as well as casualties of Kurdish revolution since 1961 now making a noticeable ratio of the disablers population in Kurdistan of Iraq. In fact, recent uprising also did contribute in raising the number of the injured and handicaps within Kurdish community. Actually, all these people almost got no easy way for participating in entertainment within this park, or any similar parks in Erbil (Hawler). All these are because of lack of suitable road and even special gates within such parks. In fact, even babies and nurseries are in need to such gate and ways that is absent so far. A review of the actual design and pointing out the stages of establishing points in this respect will be the goal of the present study for such and other parks in the region in order to reduce the existing gaps in designing, planning and in constitution of any parks. Present study is concentrating on the effect on disablers, the psychological and physical effects on crippled individuals, and the effects on disability institutions. Sami Abdulrahman Park is one of Erbil's largest parks, present study's primary goal is to build a system that addresses issues with disabled people's access to these parks. According to studies, the existence of inaccessibility is routed, and cities are referred to eliminate it; design measures with interior locations are then used to suggest presenting options. Using sketches, photos, and interviews, researchers record the park's landscape design sites—entrances, streets, pedestrian crossings, parking lots, ramps, urban furniture, etc.

Exploring the impact of landscape design on user preferences in shopping centers post the COVID-19 Pandemic

This study explores the impact of landscape design, which has gained importance alongside architectural changes in shopping centers, and investigates preferences in the post-COVID-19 pandemic era. Although e-commerce has increased during the pandemic, research and societal behaviors suggest that shopping centers will continue to serve as contemporary agoras due to their socialization and leisure functions. However, in response to the pandemic, it is anticipated that newly designed shopping centers will be architecturally conceived as semi-outdoor or outdoor spaces, regardless of climate conditions. This transformation will involve the softening of rigid appearances through landscape elements, making them both ecologically and psychologically sustainable. The number of studies on this subject is limited. To address this knowledge gap, an online survey was conducted with 586 randomly selected users across nine shopping centers located in three major cities of Turkey: Istanbul, Ankara, and Izmir, with three shopping centers in each city. The survey investigated users' preferences for architectural styles (indoor, semi-outdoor, or outdoor) and landscape design in shopping centers. The findings of the study indicate that post-pandemic, outdoor and semi-outdoor shopping centers are likely to be preferred more frequently. An emphasis is likely to be placed on natural landscape elements such as plants and water features in landscape design. Furthermore, shopping center designs are likely to become simpler, offering comfortable and spacious navigation areas while optimizing parking and transportation conditions. This study is expected to shed light on decision-making processes for future shopping centers. By incorporating consumer preferences, architects can enhance the sustainability of shopping center investments through next-generation design.

The impact of digital technologies on public life: a critical examination of perspectives from spatial design experts

ABSTRACT This study explores the influence of digital technologies on public life and evaluates spatial design professionals’ perceptions of these impacts. The research involved surveying architects, urban planners, and landscape architects to comprehend the ramifications of digital technology on public life. In total, 356 spatial design experts participated in the study. The analysis utilised descriptive statistical methods, t-tests and ANOVA tests for independent samples. The findings reveal that social isolation was rated highest among the spatial design experts’ scale, whereas social anxiety scored lowest among the elements comprising the spatial design experts’ scale. A comparison between participants’ socio-demographic characteristics and their scores on the impact of digital technologies in public life showed variances in gender, employment status, profession, and daily usage of digital technology, but found no significant differences in marital status, level of education, or professional experience. Consequently, this research sheds light on the repercussions of digital technology usage in public life, offering invaluable insights for all stakeholders, particularly spatial design professionals and social scientists. By understanding these impacts, the study highlights the importance of adopting more informed and conscious approaches to fostering positive social interactions and enhancing community well-being in public life.

The eye movement behavior induced by the design of a Japanese garden and its correlation with relaxation effects

PurposeThe design of Japanese gardens is a naturalistic style, and previous studies have shown the relaxation effects by viewing a Japanese garden. The purpose of this study is to find a trend of eye movement in viewing a Japanese garden and elucidate the relationship between eye movements and relaxation effects compared to a geometric garden.Design/methodology/approachA Japanese-style garden and a geometrically designed herbal garden were selected for the experiment. Participants' eye movement and heart rate were measured during their 5-min observation of the garden to assess their physiological responses. Additionally, POMS-SF was used to assess their psychological responses.FindingsPearson correlation analysis revealed a stronger significant correlation between eye movement data and relaxation mechanisms in the Japanese garden. Compared to the herbal garden, the Japanese garden had more fixations and faster eye movement speed, and better relaxation effects.Practical implicationsThis study suggests that exploring the relationship between design, eye movement, and relaxation mechanisms from different perspectives of landscape design is feasible. For example, our results demonstrate that the layout of landscape elements, texture, details, and maintenance in the Japanese garden hold participants' longer attention, resulting in a better relaxation effect.Originality/valueThis study clarified how a garden design can manipulate eye movements to induce relaxing effects.

Optimizing lawn grass species for turf establishment as mono-stand and mixtures under mid hill conditions

Lawn performs best with minimum inputs when grown in mixtures using more than a single grass specie. A study was conducted under open field conditions to evaluate the performance of four lawn grass species as mono-stand and in mixtures under mid-hill conditions at the Experimental Farm of the Department of Floriculture and Landscape Architecture, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during March, 2020 to March, 2021. The experiment was laid out in a randomized block design with twelve treatments and three replications. Data was recorded at fortnight intervals for total weed count, chlorophyll content, number of mowing, and overall presentability just after turf establishment. It was observed that all turf grass mixtures, performed better than the monostands, during the entire course of the study. Turf grass mixture (50% ‘Agrostis stolonifera’ + 20% ‘Festuca rubra’ + 20% ‘Lolium perenne’ + 10% ‘Cynodon dactylon)’ required least number of mowing and was presentable throughout the year attaining highest presentability score of 22.98.

Foliar application of nutrient formulation enhances the post-harvest quality of tuberose (Agave amica Medik.) cv. Arka Prajwal

A study was conducted at the Department of Floriculture and Landscape Architecture Laboratory to investigate the influence of various nutrient formulations on the post-harvest quality of tuberose using a knapsack sprayer and drone. The treatments involved spraying macro and micronutrients along with growth regulators at different concentrations. Throughout the experiment, all parameters were recorded at 2 days intervals. Drone spray of MN mixture + 0.5 % poly feed + 0.6 % humic acid + 150 ppm GA3 recorded the maximum plant post-harvest quality attributes over other treatments. It showed increased post-harvest quality attributes, including relative water content percentage of flower (95.15 %), physiological loss of weight percentage of flower (14.83 %), shelf life at room temperature (3.79 days) and vase life (12.45 days). Additionally, the treatment was found to be the best for parameters of water uptake (38.45 g) and percentage of floret opened (27.02). Plots treated with drone spray of MN mixture + 0.5 % poly feed + 0.6 % humic acid + GA3 at 150 ppm showed a reduced rate of transpiration loss of water (14.89 g) and electrolyte leakage (12.52). The experimental findings demonstrated that foliar application of nutrients along with growth regulators at different concentrations using drones improved the post-harvest quality of tuberose.

Street landscape environment design based on visual technology and entertainment robots: Computer simulation gamification landscape design

In recent years, with the development of social economy and the innovation of science and technology, the street landscape environment design based on visual technology and entertainment robot has been widely concerned. This paper aims to explore how to use computer simulation and gamification design methods to enhance the entertainment and attractiveness of street landscapes. In this paper, the basic principles of computer vision and V2X vehicle networking are deeply studied, and a series of simulation experiments and data analysis are carried out in combination with actual scenarios to verify the feasibility and effectiveness of V2X vehicle networking mode based on computer vision in urban street landscape design. V2X vehicle networking mode through real-time information exchange with road infrastructure, other vehicles, pedestrians, etc., can obtain a large number of urban streetscape design related data. Studies have shown that this design approach can increase people’s interest and engagement in street landscapes, and increase the entertainment experience and sense of interaction of urban residents.

Application of gamification based virtual robots in urban landscape Design: Interaction and entertainment experience in the design process

The traditional design process lacks fun and participation, so new elements need to be introduced to enhance the attraction and creativity of the design. The goal of the research is to design an urban landscape design method based on gamified elements and virtual robots to increase the interactivity and entertainment experience in the design process, and to explore its impact on the design results. This paper proposes an urban landscape design framework based on gamified elements and virtual robots, which includes multiple stages in the design process, each of which introduces different gamified tasks and interactions of virtual robots. Designers can gain new design ideas and inspiration by completing tasks and interacting with virtual robots. The study evaluated the effects of design methods using gamification elements and virtual robots on the design process and design results. The results show that this approach effectively increases the engagement and enjoyment of the design process, while also promoting innovation and sustainability of the design results. The urban landscape design method based on gamification elements and virtual robots has broad application prospects, which can bring more creativity and fun to urban landscape design.

Animal-Aided Design – planning for biodiversity in the built environment by embedding a species’ life-cycle into landscape architectural and urban design processes

There are suggestions of how to integrate biodiversity-friendly measures into both architecture and landscape architecture, however it is unclear how to systematically include the needs of other organisms such as animals. One particular challenge is the conflict between amenity and biodiversity, as the human designer aims for good design, which often appears to be incompatible with biodiversity-friendly measures. Here we describe ‘Animal-Aided Design’ (AAD) as a methodology to systematically include animals into the planning cycle of project-based planning. The basic idea of AAD is to make animals an integral part of the design and define their needs at the beginning of the planning process. The requirements of target species then set boundary conditions for the planning process, but also serve as an inspiration for the design itself. We illustrate our methodology using theoretical examples, mostly from Western Europe, in particular Germany.
