Abstract West Binjai is a sub-district located in Binjai City, North Sumatra. Green Open Space is also part of the Binjai city’s planning scheme which has many benefits for the community and the environment. This research used Normalized Difference Vegetation Index (NDVI) analysis and NDVI value classification results in the distribution of vegetation density. Analysis of changes in vegetation density was carried out between 2015 and 2020 in West Binjai. The largest change in the area of vegetation density classes in the West Binjai between 2015 and 2020 was the increase in the area of the high dense class to 19.13%. The sub-district has green open spaces in the form of sub-district parks, public cemeteries, road green lane, river bank and private green open spaces. These green open spaces were in the low dense, medium, dense and high dense classes. There is a need for rearrangement of green open spaces, especially those within low dense class. Replanting trees are also essential to increase the quality of the green area. Improving the quality of green space will lead to the enhancement of quality of environment.

Open Space Planning

Growing urbanization poses an enormous challenge to city planners. Noticeable effects of the increased population density in cities include housing shortages, rising real estate prices, increased traffic, air pollution, shortages of green spaces and attractive public spaces, the rising cost of urban infrastructure and the risk of social tensions. Especially in dense urban areas, public open spaces (squares and streets, urban parks and spacious recreational areas) have become increasing important. Their design, functionality and the adaption to the needs of the residents significantly influences the quality and atmosphere of urban coexistence. The consideration of quality criteria is essential for the creation of sustainable, livable and smart open spaces. Modern approaches to sustainable planning in urban areas and the versatile aspects of state-of-the-art open space design are the core themes of this article. General aspects of landscape planning in Austria and selected best practice projects in the context of urban development are presented.This article gives an overview of open space planning in Austria. To be successful, projects must consider the specific needs of city districts, which requires tailor-made approaches and an interdisciplinary planning team. To be accepted and adequately used by the public, projects must be based on a detailed analyses of the spatial, natural and social conditions.The complex and diverse challenges of open space planning in Austrian cities can be seen as representative for other cities, as certain urban trends occur (in slightly altered dimensions) all over Europe or on an even bigger scale. Selected best practice urban planning projects, which have been realized by freiland Environmental Consulting CE Ltd, based on state-of-the-art principles, demonstrate modern planning approaches to tackling these challenges.

Wildlife Populations

AbstractGreen areas drawn on a city plan represent open spaces that have different meanings for humans and wildlife. Diverse kinds of green may influence species viability in urban environments. It is necessary to understand what those areas mean for wildlife populations and how land-use changes affect habitats and movements for making scientifically defensible planning and design decisions. My objective was to demonstrate how open space and urban development patterns affect the viability of wildlife populations in urbanizing landscapes from a movements perspective. Eight scenarios for 2060 for an urbanizing area near Portland, Oregon combined four open space (none, corridors, parks, and network) with two urban development patterns (compact and dispersed). Dispersal model HexSim simulated three target species – Red-legged frog (Rana aurora aurora), Western meadowlark (Sturnella neclecta) and Douglas squirrel (Tamasciurus douglasii) – movements on those scenarios to compare and contrast sustained populations to the ca. 2010 baseline landscape. Network scenarios presented the largest number of frog breeders. Greenway scenarios showed the largest populations of squirrels. Park and network scenarios sustained viable populations of meadowlarks, but park scenarios performed best. Compact development scenarios performed best for most indicators, while dispersed development scenarios performed better for meadowlarks. Network scenarios performed best when considering the collective of species. Networks presented more diverse habitats, sustaining higher diversity of species. For plans to sustain more species, more comprehensive and diverse habitats must be promoted, otherwise trade-offs should be expected – like the extinction of meadowlarks in greenway scenarios.

Looking at the urban development of the past two centuries, we can conclude that engineers and architects have been dominating the field of urban design all over Europe. Architects played the most important role, which became even more significant with the increase of urban development. Beyond the architectural approach, a greater importance had been attributed to ecological aspects of urban planning by the turn of the 20th century as, for example, the advance of the garden city movement illustrates. This article focuses on the review of crucial open-space renewal projects from two Eastern European cities and China. The case studies are used to shed light on the characteristics and historical values of contemporary open-space design, based on innovative and landscape architectural approaches and artistic solutions. The study shows that the original role of urban open spaces was significantly extended during the first decades of the 21st century. The increased needs for representation—commercial, cultural and living functions, and ecological and healthy benefits—led to a multifunctional approach in design and planning. The renewal of the historic urban open spaces is carried out under an integrated framework and a unified goal: the development-oriented heritage conservation. Based on strong economic aspects, the general tendency is clearly positive—in spite of still-existing problematic issues (for instance, the management of public transport or the status of public utilities). In the time of a growing awareness of open-space heritage, this overview tries to depict possible general principles of a long-term renewal strategy built on local identity, heritage values and social sustainability.

Abstract As the city grows, more and more vegetated land is converted to non-vegetated land. This also occurred at Binjai, a city in the North Sumatera Province, Indonesia. The aim of this study was to examine the urban vegetation cover and its changes between 2015 and 2019. The research was carried out in Binjai Timur, which is one of Binjai’s sub-districts. The distribution of vegetation density was measured using the Normalized Difference Vegetation Index (NDVI) value classification. The decrease in the dense class to 10.08 percent was the most significant change in vegetation density class between 2015 and 2019. This was followed by an 8.87 percent increase in the high-density class. This indicates that there is an area with vegetation density increased from lower density to high density. The district has green open spaces in the form of a neighborhood park, cemetery, sub-district park, greenbelt along the road and river, and house yards, according to the field check. These green open spaces were located in low and medium-density areas. The findings suggest that planting trees in those locations and arrangement of vegetation within parks could improve its quality and function. For good quality of urban environments, it is optimizing the use of house yards as vegetated land and boosting green open space quality is required.

Public open space (POS) in Ankara reflects both the negative and positive aspects of urban change. Evolving public space development strategies in Ankara played a fundamental role in the protection, promotion, and enhancement of POS from 1923 to 2017. This study shows that while the POS development of the city was addressed as an integrative and comprehensive structure in the entire city by the Lörcher (1924–1925) and Jansen (1932) plans, the subsequent approaches to POS were more superficial, piecemeal, and simplistic.

Abstract: This research aims to analyze the impact of Janti Flyover Construction toward the growth of layout at Janti Urban Area, including structured space, open space, and linkage. Method used for data collecting are observation, air photograph monitoring, and interview, whereas the analysis method is qualitative description, which is the superimposed method of two layers, that are the layout condition before and after flyover construction. The result shows that the impact of Janti Flyover construction can be seen on building mass (solid), the increasing number of open spaces, including the road network, parking place, and park, whereas the relation between spaces, visually and structurally, can be seen on the growth of buildings which have new shapes and styles, therefore the performance of the overall building does not have a proportional shape. Considering Janti Street at the collective relation, its role is getting stronger as the main frame road network.Keywords: Flyover construction, layout changing, Janti AreaAbstrak: Penelitian ini bertujuan untuk menganalisis pengaruh pembangunan Jalan Layang Janti terhadap perkembangan tata ruang Kawasan Janti, meliputi ruang terbangun, ruang terbuka, serta hubungan antar ruang (“linkage”).

Quantitative and accurate urban land information on regional and global scales is urgently required for studying socioeconomic and eco-environmental problems. The spatial distribution of urban land is a significant part of urban development planning, which is vital for optimizing land use patterns and promoting sustainable urban development. Composite nighttime light (NTL) data from the Defense Meteorological Program Operational Line-Scan System (DMSP-OLS) have been proven to be effective for extracting urban land. However, the saturation and blooming within the DMSP-OLS NTL hinder its capacity to provide accurate urban information. This paper proposes an optimized approach that combines NTL with multiple index data to overcome the limitations of extracting urban land based only on NTL data. We combined three sources of data, the DMSP-OLS, the normalized difference vegetation index (NDVI), and the normalized difference water index (NDWI), to establish a novel approach called the vegetation–water-adjusted NTL urban index (VWANUI), which is used to rapidly extract urban land areas on regional and global scales. The results show that the proposed approach reduces the saturation of DMSP-OLS and essentially eliminates blooming effects. Next, we developed regression models based on the normalized DMSP-OLS, the human settlement index (HSI), the vegetation-adjusted NTL urban index (VANUI), and the VWANUI to analyze and estimate urban land areas. The results show that the VWANUI regression model provides the highest performance of all the models tested. To summarize, the VWANUI reduces saturation and blooming, and improves the accuracy with which urban areas are extracted, thereby providing valuable support and decision-making references for designing sustainable urban development.

Public open spaces services have been shown to be profoundly affected by rapid urbanization and environmental changes, and in turn, they have influenced socio-cultural relationships and human well-being. However, the impact of these changes on public open space services (POSS) remains unexplored, particularly in the Saudi Arabian context. This study examines the socio-cultural influence of POSS on the King Abdulaziz University campus, Jeddah, Saudi Arabia and the impact of these services on well-being. A field survey and questionnaire were used to collect data. Non-parametric tests (Kruskal–Wallis and Mann–Whitney tests) were used to find significant differences in the importance of POSS as perceived by stakeholders based on socio-demographic attributes. Factor analysis was performed for 14 POSS to identify those that are most important. The study showed that (i) university stakeholders are closely linked to services provided by public open spaces (POS) and dependent on POSS, (ii) there were significant differences in the perceived importance of POSS according to gender, age, and social groups, and (iii) 70 to 90% of stakeholders reported POSS as having a positive impact on well-being. Thus, the findings will help design and plan POSS to meet the needs of society and promote well-being.
