A social-ecological perspective for emerging cities: The case of Corniche promenade, “urban majlis” of Doha

In the past decade, the capital city of Doha of the State of Qatar has experienced rapid urban expansion and other changes due to globalization, which has caused (i) the loss of a compact urban pattern, (ii) landscape fragmentation, and (iii) deficiency of green spaces. Therefore, as envisioned by Qatar National Vision 2030 (QNV-2030), the State of Qatar plans to invest substantial funds into the urban regeneration of the built environment, along with the development of large areas of public parks as a means of promoting more sustainable urban development and enhancing city residents’ well-being. Accessibility contributes to the usability of public facilities on the part of the neighborhood community, thus enhancing city dwellers’ well-being. Nonetheless, the authors argue, the urban network along Doha’s Corniche promenade, the dominant open public space and the spine of the city, lacks connectivity at various scales of space. Therefore, this research study aimed to assess the existing conditions of Doha’s Corniche and recommend strategies for implementing its integration into the newly emerging city’s urban fabric. The findings, revealed through a network-analysis investigation based on graph theory, allowed us to generate a framework for shaping open public spaces, promoting higher living standards through a green network system planned at the city scale. The proposed framework addresses social-ecological challenges of distinctive open public spaces and helps define an approach for (i) tailoring the accessibility of open public spaces to their surroundings, and (ii) enhancing city dwellers’ well-being.

Planning for a neighborhood and city-scale green network system in Qatar: the case of MIA Park

In the past decade, Doha has witnessed fast-urban growth, an increased population rate, and an over-reliance on the automobile as the main mode of urban transportation. These factors caused social and environmental problems related to (1) the loss of a compact urban pattern, (2) an increased level of air pollution (3) high traffic congestions and (4) increasing landscape fragmentation. In consideration of such concerns, The State of Qatar invested large funds into the urban landscape development of Doha, as envisioned by Qatar National Vision 2030. As a result, in the past five years various parks and/or green areas, such MIA Park, a major public green space located around the Museum of Islamic Art (MIA), were planned and developed within metropolitan Doha. The authors argue that this park is currently facing issues and challenges related to (1) accessibility to/from the neighboring districts, and (2) connectivity to/from the neighboring parks. Therefore, this research study aims at assessing the existing conditions of MIA Park, at considering the broader city context and, at recommending strategies for implementing MIA Park’s green network system. It approached the investigative challenge using a multi-pronged comprehensive methodology, that deployed focus groups, semi-structured interviews and a comprehensive network analysis based on graph theory. The findings, revealed through these hybrid research tactics, allowed the researchers to generate a framework to enhance accessibility and connectivity of MIA Park through a green network system, planned at inter-related neighborhood-scale and city-scale levels. While the research examines most notably a single case, it is advocated that the proposed framework represents not just an optional feature pertaining to the case in Doha, but a valuable reference for the sustainable master planning of future cities in the State of Qatar and across the GCC. The paper proffers numerous key contributions, including the critical exploration of manufactured landscapes in Doha Qatar and the delineation of broadly applicable environmental design strategies to improve the fabric and livability of cities.

Biodiversity as Part of Urban Green Network System Planning Case Study: Pontianak City

Urban ecology is a new paradigm in viewing urban area as human-dominated ecosystem. This kind of ecosystem consists of socio-cultural as well as economical aspects which play important roles. Recently, urban ecosystem had caused major ecological problems such as flood, Urban Heat Island, pollutions, and biodiversity loss. Green network system is crucial factor in urban ecology and become an alternative approach to overcome ecological problems in urban areas. Urban green space in a form of parks (patch) and corridors are integral part of green network system, therefore they are potential urban fabrics (Hough, 1989). Due to specific social and ecological function, green open space in high density settlement should integrate these functions. On the other hand, urban biodiversity serve as indicator of environment quality (Muller, 2013). The aim of this paper is to identify urban biodiversity in the city as a base for planning an urban green network system.

Green network automatic abstraction algorithm

With the rapid development of Internet,the traditional automatic Abstraction algorithm cannot meet the needs of the green network.Different from the traditional automatic Abstraction algorithm based on statistical learning,this paper proposed a new algorithm based on clear semantics.It made use of cloud data acquisition library of green network system based on behavior analysis and Wikipedia resources as the knowledge base to establish the concept of space,it performed semantic interpretation on these words.Finally,the experimental results prove that the proposed method can cover more information with fewer sentences compared with the traditional algorithm,thus it greatly shortens the time for the system to analyze and filter inappropriate content and enhances the quality of software services.

Comprehensive concept planning of urban greening based on ecological principles: a case study in Beijing, China

Greenspace is an important part of complex urban ecosystems and provides significant ecosystem services. It benefits urban communities environmentally, esthetically, recreationally and economically. Beijing Province is in north of China, and has a total area of 16,807.8 km 2 and a population of about 13.8 million. This paper aims to develop a comprehensive conceptual framework for urban greening of Beijing Province based on landscape ecological principles. It attempts to answer how to establish an urban greening plan at the regional, city and neighborhood levels to achieve long-term sustainability. At the regional level, a big natural and semi-natural forest area in the northwest and an ecological buffer belt in the southeast are planned to protect the environmental quality of Beijing and provide habitats for wildlife. At the city level, a green network system of green wedges, parks and green corridors has been proposed. This green network helps to limit future urban expansion, improve urban environmental quality and serve as habitats and migration routes for wildlife. At the neighborhood level, green extensions and connections of riverside greenway, road greenway, parks and vertical greening permeate into the built-up areas. They provide open space close to residential areas and offer places for recreation. This three-level green system constitutes an integrated ecological network for urban sustainable development of Beijing. For future development of Beijing, urban parks, forestry, agriculture, water and infrastructure should be planned and designed in an integrated way. After this greenspace plan is legislated and completely realized, Beijing will develop an interconnected and integrated network of urban greenspaces. It has the prospect of achieving the aim of “Green Olympic City 2008” and the long-term goal of developing Beijing towards an “Eco-City”.

도시열섬현상 저감을 위한 그린네트워크 구축 방안에 관한 연구 - 대구광역시 달서구를 대상으로 -

As urbanization has been expanded in Korea, open spaces, such as urban parks and public sites, have been utilized for other uses, and then this bring out environmental changes for the worse. It is expected that these changes become more serious problems due to overpopulation, increasing individualism, and development of transportation. This research base on the consideration of connecting between decreasing urban green spaces and distributed green sites so as to build the substantial plan for the Green Network construction for urban heat island mitigation in Dalseo district, Daegu Metropolitan City. The result were as follow; 1) Connecting existing natural sites to the remained parks green zone made an Ideal form of Green-Network system. 2) Some school sites were selected for usable open spaces in order to build Green-Network system, and the plan connecting together with exist natural sites was suggested. 3) Moreover, the scheme of planting on the road spaces for connecting green spaces was proposed. 4) The devices of planting on the urban riverside for enhancing the role of urban stream to form green network was conceived.
