Urban Footprint

Cities are expanding rapidly, and the impact of dense human-oriented urban systems on ecosystems is both direct (conversion of natural land cover to urban footprint) and indirect. Human settlements are more complex than any other ecosystems as they meet human socio-ecological needs and support local biodiversity. The open spaces of a city with rich cultural character and biodiversity have become important elements of urban design, where urban systems can be planned to coexist with local biodiversity without disturbing the ecosystem. With the need to redefine urban footprint as an ecologically rich urban environment, this chapter addresses the definition of urban open space and questions the coexistence of humans and biodiversity in urban open spaces.

The Impact

The community greenway is a kind of greenway that goes through high-density residential areas in the city and is closely related to residents’ life. However, few scholars focus on how this type of greenways serves the everyday life of the community as an integrated resource. This aspect is important because the everyday life in the public space involves multiple activities. How to coordinate and satisfy these activities relates to the benefits of community greenways. Therefore, this paper takes a representative community greenway in Haizhu District of Guangzhou as an example, to study whether community greenways match the needs of necessary activities, optional activities and social activities. The usage patterns, the evaluation of the current status, the impact on everyday activities, and the importance of different construction factors were surveyed. The applied methods include site observation, questionnaires and interviews. The results show that more than 90% of users are from communities within 1 mile from the community greenway. More than half of the users (55%) are satisfied with the community greenways. Furthermore, the community greenways benefit the everyday activities of residents, such as transportation, recreation, social interaction and also other minor but important everyday activities. However, from the perspective of residents’ requirements for construction factors, the status of service facilities needs to be improved. The characteristics, overall benefits, and construction implications of community greenways are therefore discussed. Community greenways can be important open space for residents and this paper is significant on community greenways meeting the needs of residents’ everyday activities, thus, to provide a better community living environment and to build a better urban open space system.

Urban open space which maintaining the diversity of the urban ecosystem, is an important structural element of the city. Urban development led to the isolation of open space between one another, and the ecological function and environmental function of open space greatly reduced. This article pointing out that we should protect and restore urban ecological structure, improve the open space network, strengthen the links between open space, take low impact development approach to reduce the impact of urban development on the natural environment and restore the ecological functions of open space.

The Impact

Many big, average and even small towns have been dramatically car-invaded through the past twenty years in Eastern Europe. That resulted in fragmented open spaces and endangered mobility through the streets and blocks of the city. The paper addresses the issue of comfortable access to urban open space by bringing the multidimensional approach that includes aesthetical, infrastructural and social tools and applications. On the example of Joniškis town in Lithuania, the paper presents a solution toolkit for assessing the existing mobility situation, developing a re-pedestrianising action plan and programming the impact of the applied measures. The results of the multidimensional approach show that by giving priority for pedestrians against cars in urban open spaces and drive-ins cities can achieve multiple environmental and social-economic benefits. Open spaces become safer, more attractive and pleasing and more people visit them. The proposed model serves as a continuous professional development topic for landscape architects researching, teaching and designing in the private, public and non-governmental sectors.

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”). Metode pengumpulan data dilakukan melalui observasi, pengamatan foto udara, dan wawancara; sedangkan metode analisis melalui deskripsi secara kualitatif yang berupa “superimposed method” dari dua lapisan kondisi lahan, yakni kondisi tata ruang sebelum dan sesudah pembangunan jalan layang. Hasil penelitian menunjukkan bahwa pengaruh pembangunan Jalan Layang Janti terdapat pada massa bangunan (“solid”), pertambahan ruang terbuka yang berupa jaringan jalan, parkir, dan taman; sedangkan pada hubungan antar ruang ̶ secara visual dan struktural ̶ yakni tumbuhnya bangunan dengan bentuk dan gaya baru, sehingga bentuk tampilan bangunan secara keseluruhan tidak proporsional. Pada hubungan kolektif, Jalan Janti semakin kuat perannya sebagai kerangka utama jaringan jalan.Kata kunci : Pembangunan jalan layang, tata ruang, Kawasan Janti

In 1880, when the British moved their Federated Malay States administrative centre to Kuala Lumpur, the Padang quickly became a symbol of British economic and administrative colonisation, and a nucleus of the socio-cultural development of Kuala Lumpur. This paper discusses the layers of history, symbolism and cultural values that the Padang contributes to the socio-cultural tapestry of both Kuala Lumpur and Malaysia, and the lack of relevant planning and heritage measures to conserve these attributes and characteristics. The conclusions offer avenues to engage with pre- and post-colonisation that enable re-making and the conservation of the iconic space of Kuala Lumpur.Keywords: Urban open space; Merdeka Square; Kuala Lumpur City Hall; National Heritage Act 2005eISSN: 2398-4287 © 2019.

The Impact

Between the ages of 6 and 18, children spend between 30 and 42 h a week at school, mostly indoors, where indoor environmental quality is usually deficient and does not favor learning. The difficulty of delivering indoor air quality (IAQ) in learning facilities is related to high occupancy rates and low interaction levels with windows. In non-industrialized countries, as in the cases presented, most classrooms have no mechanical ventilation, due to energy poverty and lack of normative requirements. This fact heavily impacts the indoor air quality and students’ learning outcomes. The aim of the paper is to identify the factors that determine acceptable CO2 concentrations. Therefore, it studies air quality in free-running and naturally ventilated primary schools in Chile, aiming to identify the impact of contextual, occupant, and building design factors, using CO2 concentration as a proxy for IAQ. The monitoring of CO2, temperature, and humidity revealed that indoor air CO2 concentration is above 1400 ppm most of the time, with peaks of 5000 ppm during the day, especially in winter. The statistical analysis indicates that CO2 is dependent on climate, seasonality, and indoor temperature, while it is independent of outside temperature in heated classrooms. The odds of having acceptable concentrations of CO2 are bigger when indoor temperatures are high, and there is a need to ventilate for cooling.

AbstractAn urban mobility transition requires a transition in space allocation, since most mobility modes are dependent on urban open space for circulation and the storage of vehicles. Despite increasing attention to space and spatiality in transitions research, the finite, physical aspects of urban space, and the means by which it is allocated, have not been adequately acknowledged as an influence on mobility transitions. A conceptual framework is introduced to support comparison between cities in terms of the processes by which open space is (re-)distributed between car and bicycle circulatory and regulatory space. This framework distinguishes between regulatory allocation mechanisms and the appropriation practices of actors. Application to cases in Amsterdam, Brussels and Birmingham reveal unique relationships created by the zero-sum nature of urban open space between the dominant automobility mode and subordinate cycling mode. These relationships open up a new approach to forms of lock-in that work in favour of particular mobility modes within the relatively obdurate urban built environment. Empirically, allocation mechanisms that routinise the production of car space at national level within the EU are shown to be far more prevalent than those for bicycle space, highlighting the constraints faced by radical city-level policies aimed at space reallocation.

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.
