Design with Microclimate
Design with Microclimate argues that, as the climate changes and fuels become increasingly expensive, appropriate design of outdoor spaces will become critical. In this practical, informative book, Robert Brown uses vivid illustrations and examples and provides practical tools that can be used in everyday design practice. The heart of the book is Brown's own design process, as he includes useful guidelines to lead designers clearly through the complexity of climate data, precedents, site assessment, microclimate modification, communication, design, and evaluation. Brown strikes an ideal balance of technical information, anecdotes, examples, and illustrations to keep the book engaging and accessible. His emphasis throughout is on creating microclimates that attend to the comfort, health, and well-being of people, animals, and plants.
Determining the bioclimatic comfort in Kastamonu City
Bioclimatic comfort defines the optimal climatic conditions in which people feel healthy and dynamic. Bioclimatic comfort mapping methods are useful to urban managers and planners. For the purposes of planning, climatic conditions, as determined by bioclimatic comfort assessments, are important. Bioclimatic components such as temperature, relative humidity, and wind speeds are important in evaluating bioclimatic comfort. In this study of the climate of Kastamonu province, the most suitable areas in terms of bioclimatic comfort have been identified. In this context, climate values belonging to the province of Kastamonu are taken from a total of nine meteorological stations. Altitude (36–1050 m) between stations is noted for revealing climatic changes. The data collected from these stations, including average temperature, relative humidity, and wind speed values are transferred to geographical information system (GIS) using ArcMap 10.2.2 software. GIS maps created from the imported data has designated the most suitable comfort areas in and around the city of Kastamonu. As a result, the study shows that Kastamonu has suitable ranges for bioclimatic comfort zone. The range of bioclimatic comfort value for Kastamonu is 17.6 °C. It is between a comfort ranges which is 15–20 °C. Kastamonu City has suitable area for bioclimatic comfort.
The positive carbon stocks–biodiversity relationship in forests
Carbon storage in forests and its ability to offset global greenhouse gas emissions, as well as biodiversity and its capacity to support ecosystem functions and services, are often considered separately in landscape planning. However, the potential synergies between them are currently poorly understood. Identifying the spatial patterns and factors driving their co-occurrence across different climatic zones is critical to more effectively conserve forest ecosystems at the regional level. Here, we integrated information of National Forest Inventories and Breeding Bird Atlases across Europe and North America (Spain and Quebec, respectively), covering five subclimates (steppe, dry Mediterranean, humid Mediterranean, boreal, and temperate). In particular, this study aimed to (1) determine the spatial patterns of both forest carbon stocks and biodiversity (bird richness, tree richness, and overall biodiversity) and the factors that influence them; (2) establish the relationships between forest carbon stocks and biodiversity; and (3) define and characterize the areas of high (hotspots) and low (coldspots) values of carbon and biodiversity, and ultimately quantify their spatial overlap. Our results show that the factors affecting carbon and biodiversity vary between regions and subclimates. The highest values of carbon and biodiversity were found in northern Spain (humid Mediterranean subclimate) and southern Quebec (temperate subclimate) where there was more carbon as climate conditions were less limiting. High density and structural diversity simultaneously favored carbon stocks, tree, and overall biodiversity, especially in isolated and mountainous areas, often associated with steeper slopes and low accessibility. in addition, the relationship between carbon stocks and biodiversity was positive in both regions and all subclimates, being stronger where climate is a limiting factor for forest growth. The spatial overlap between hotspots of carbon and biodiversity provides an excellent opportunity for landscape planning to maintain carbon stocks and conserve biodiversity. The variables positively affecting carbon and biodiversity were also driving the hotspots of both carbon and biodiversity, emphasizing the viability of “win-win” solutions. Our results highlight the need to jointly determine the spatial patterns of ecosystem services and biodiversity for an effective and sustainable planning of forest landscapes that simultaneously support conservation and mitigate climate change.
Mapping of bioclimatic comfort for potential planning using GIS in Aydin
People are relaxed (satisfied or well-off) in what is described as comfortable climatic conditions. In such conditions, a person’s energy balance is not disturbed because of stresses from extreme heat or cold. Bioclimatic structure has been well researched and should be a consideration in the planning process for arranging comfortable spaces. It represents the understanding that energy balance is one of the basic elements of a sustainable landscape design. The goals of this study have been to create ideal places for human thermal comfort and to advance objectives focused on the importance of sustainable and ecological landscape planning and design work, along with their accompanying economic benefits. In this study, which focuses on the climate of the Province of Aydin, the most suitable areas for bioclimatic comfort have been identified. The climate values for the Aydin Province have been taken from a total of 22 meteorological stations. Stations at altitudes ranging from 11 to 871 m were used to note the climate changes that occurred. The average temperature, relative humidity, and wind speed from each station, including data collected using Geographic Information System (GIS) software, were transferred. GIS maps were then created from the imported data, and areas of optimal comfort around the city of Aydin were determined. The results show the range that is suitable for a bioclimatic comfort zone in Aydin. The bioclimatic comfort range was determined to be roughly 17 °C for Aydin, and the city of Aydin demonstrated a comfort range between 14 and 19 °C. As a result, the city of Aydin was shown to be a suitable area for bioclimatic comfort.
Land surface temperature relation with normalized satellite indices for the estimation of spatio-temporal trends in temperature among various land use land cover classes of an arid Potohar region using Landsat data
In terrestrial landscape architecture, land surface temperature (LST) is a key estimator of local climate, vegetation growth, and urban transition. It also represents the environmental factors that influence the land cover patterns using temperature variation over land use land cover (LULC) classes. In the present study, various geospatial techniques have been implemented to analyze the spatio-temporal trends in temperature among different LULC of an arid Potohar region of Pakistan using Landsat 7 (ETM+) and 8 (OLI & TIRS) and the relationship between different normalized satellite indices and LST. Results of the seasonal fluctuation in winter showed temperature range of 0–57, 0–50, 04–31 and 7–39 °C for the year 2000, 2005, 2010, and 2015, respectively, while the summer exhibited the temperature range of 24–48, 27–57, 22–48, and 12–41 °C for the year 2000, 2005, 2010, and 2015, respectively. The analysis established a direct correlation between LST and normalized difference vegetation index and normalized difference water index, and an indirect correlation among LST and normalized difference soil index, normalized difference built-up index and built-up index. The findings are critically important for planning and development division for sustainable use of land resources for urbanization extension projects. Future research will highlight the change in the area occupied by different land featured classes and their impacts on LST over a specified period.
Design and Site-Related Factors Impacting the Cooling Performance of Urban Parks in Different Climate Zones: A Systematic Review
As cities expand rapidly, the combined effects of urbanization, global warming, and the intensification of the Urban Heat Island (UHI) phenomenon have become more challenging for urban environments. In response, Urban Green Infrastructure (UGI) has gained attention as a practical and effective tool for mitigating UHI and improving climate change. Among various UGIs, urban parks have been the subject of numerous studies due to their proven ability to reduce air and surface temperatures, improve local microclimates, and enhance overall urban livability. This systematic review synthesizes the existing body of research to identify key factors that influence the cooling performance of urban parks. A total of 131 peer-reviewed studies between 2014 and 2024 were analyzed, focusing on both design-related and site-related factors that play pivotal roles in a park’s cooling effectiveness. Design-related factors include park size, shape, vegetation density and composition, the presence of water bodies, and impervious surfaces while site-related factors encompass background climate conditions, the proximity to natural water bodies, and the urban configuration surrounding the parks. The findings reveal that park size, tree coverage, and the presence of water bodies are the most influential design-related factors in enhancing cooling performance. For site-related factors, wind speed and direction emerged as critical components for maximizing cooling benefits. Research also showed urban configuration can affect the overall cooling performance by influencing airflow patterns and shading. Understanding these dynamics is crucial for cities worldwide as they strive to design parks that address their specific environmental and climatic challenges. The findings of this review offer practical guidance for landscape architects and urban planners, enabling them to design parks that deliver enhanced cooling benefits, especially when cities face rising temperatures and an increasing number of heatwaves.
Land use/land cover changes (LULCC) using remote sensing analyses in Rizal, Philippines
Changes in landscapes throughout time are primarily affected by a wide variety of factors, such as climatic conditions, anthropogenic activities, and even ecological successions. Land use land cover changes in the province of Rizal were traced from 1993 to 2020 using remotely sense images from Landsat collection 1-Level 1 (Landsat 4–5™ C1- Level 1 & Landsat 8 OLI/ TIRS C1 Level 1) on USGS EarthExplorer to be able to assess the changes in the landscape, since it was subjected to high rates of urbanization, drought episodes and major deforestation practices throughout the years. The accuracy of the classified LULC maps through supervised and Maximum Likelihood classification in ArgGIS 10.8 were assessed, with overall accuracies ranging from 84 to 90, and generating Kappa coefficients that ranges from 0.73 to 0.82. The increase of vegetation cover was observed primarily due to secondary succession following episodes of drought and reforestation efforts in the landscape. The conversion of barren lands to settlements and agricultural lands were brought about by the increasing population rate and economic growth in the province, since it is one of the neighboring provinces of Metropolitan Manila. The LULCC of the province throughout the time span studied is a pivotal component in terms of environmental changes. By means of the detection of these changes, and with these data at hand, mitigation of future threats and the protection of the biodiversity of the area can be further strengthened through policy suggestions, with proper landscape planning and monitoring partnered with local government units and stakeholders.
Thermal comfort perception among park users in Prague, Central Europe on hot summer days—A comparison of thermal indices
The assessment of human perception of the thermal environment is becoming highly relevant in the context of global climate change and its impact on public health. In this study, we aimed to evaluate the suitability of the use of four frequently used thermal comfort indices (thermal indices)–Wet Bulb Global Temperature (WGBT), Heat Index (HI), Physiologically Equivalent Temperature (PET), and Universal Thermal Climate Index (UTCI)–to assess human thermal comfort perception in three large urban parks in Central Europe, using Prague, the capital of the Czech Republic, as a case study. We investigated the relationship between the four indices and the thermal perception of park visitors, while taking into account the effect of the sex, age, and activity of the respondents and the week-time and daytime of their visit (assessed parameters). Park visitors were interviewed during the summertime, while collecting meteorological data. The correlations were performed to explore the relationship between the thermal perception and the individual thermal indices, multivariate statistical methods were used to explain how well the variation in thermal perception can be explained by the assessed parameters. We found a significant association between all the indices and thermal perception; however, the relationship was the strongest with HI. While thermal perception was independent of sex and week-time, we found a significant effect of age, physical activity, and daytime of the visit. Nevertheless, the effects can largely be explained by thermal conditions. Based on the results, we conclude that all the investigated indices are suitable for use in studies of thermal comfort in parks in Central Europe in summertime, while HI seems the most suitable for architects and planners.
Perception of the Vegetation Elements of Urban Green Spaces with a Focus on Flower Beds
Urban vegetation plays a crucial role in meeting the challenges posed by rapid urbanization and climate change. The presence of plants and green spaces in urban areas provides a variety of environmental, social, and economic benefits. Understanding how users perceive ornamental plants in public green spaces and what their preferences are for certain vegetation elements is extremely important for planning and designing functional and aesthetically interesting urban landscapes. Although landscape experts sometimes use their creativity to create new trends, it is important not to ignore the attitudes and preferences of the public, who sometimes have a different opinion from that of the experts. The aim of the study was to determine the perceptions and preferences of the public and landscape experts for different vegetation elements and the differences in attitudes between these two groups. The study was conducted in Croatia in April 2012 using an online survey (n = 348). The results showed that trees were the most preferred vegetation element and that the public preferred flower beds and lawns to a greater extent than the professionals. All respondents perceived vegetation elements as volumes (trees, shrubs, and hedges) and plains (flower beds and lawns). In addition, respondents perceived two basic types of flower beds according to the features that characterize them: conventional and sustainable. The results show that users perceive the functional and spatial characteristics of the different vegetation elements, which is very important for the design of functional and sustainable urban green spaces.
