In densely populated settings like Chittagong, Bangladesh cities facing rapid urbanization and economic growth are challenged to provide open space for its citizens. For example, the population of this port city is 14,200 people per square kilometer and there is a struggle to provide open space. Again, the planning proposal did not set any open space standard to achieve its open space aspirations Hence, the objectives of this paper are four-fold: (i) Develop an understanding of open space standards to establish relative benchmarks for potential use in Chittagong. (ii) Examine existing formal open space in Chittagong. (iii) Document the existing informal open space areas in Chittagong according to the planning direction. (iv) Recommend an approach that can be used to realize open spaces in Chittagong. To achieve these, this paper documents the existing open space scenario in the city, examines the recommended open space standards developed by organizations such as the World Health Organization (WHO) and the Dhaka Structural Plan (2016–2035) (the planning document of the capital city of Bangladesh) to identify to what extent these ‘benchmark’ standards are appropriate for use in the city. A discussion on open space in Chittagong and the criteria used to ‘frame’ open space calculations in the city is then conducted to provide a foundation to reflect upon the world’s various open space recommendations. Ultimately, by analyzing existing open space recommendations and their associated well-being aspirations, the research suggests that a new standard relating to the unique characteristics of the city should be used when developing open space standards in Chittagong.

In a densely populated setting like Chittagong, cities facing rapid urbanization and economic growth are challenged to provide the necessary open space for its citizens. For example, the population density of the port city Chittagong, Bangladesh is 14,200 people per square kilometers and struggles to meet its open space aspirations. This paper examines the recommended open space standards developed by organizations such as the World Health Organization (WHO) to identify to what extent these standards are appropriate for use in Chittagong. The WHO recommends 9 m² of open space per person. However, according to the Dhaka Metropolitan Detail Area Plan (DMDP), the plan overseeing Chittagong’s open space, the minimum requirement for this city’s population is 3.8 m² of open space per person. Yet, when the city’s existing unique natural open space system is added with the city’s existing open space network, the total open space achieved is only 0.18 m² of open space per person. Hence, a theoretical discussion on open space and the criteria used to ‘frame’ open space calculations in the city provide a foundation to examining the world’s various open space recommendations. Ultimately, the research suggests that international standards and the DMDP’s open standards are not achievable in Chittagong.

The population density in Chittagong City Corporation (CCC) area was 242.28 per square meter in 2019, and Bulmer suggests that, due to the high birth rate in Asia, cities such as Chittagong can be considered high density. Contextually, this ‘high-density’ element is a determining factor that potentially allows one to address the city’s open space standard, which “should compensate and complement the physical and social context of the [urban] surrounding environment”. The research in this paper is focused on the urban setting, defined in the CCC area of 168 square kilometres. The literature review and case study analysis found that per capita open space in Chittagong is far lower than the WHO recommendation (nine square meters per person). Additionally, the UN stated that “47% of [the city’s] population live within 400 m walking distance to open public spaces”, whereas, according to the previous study, in Chittagong City only 19% of residents live within this distance. Observing these issues, the aim of the paper is to develop an innovative way to obtain per capita open space in Chittagong city. To achieve the aim, the researchers analysed the data from surveys and interviews conducted by using SPSS and NVivo. These tools produced data that were, for example, used to develop themes of open space in Chittagong. This investigation and analysis of material allowed for the generation of strategies and planning recommendations to improve the open space situation in the city. Beyond these strategies, the research team produced new insights to promote sustainability in this area.
