Does building development in Dhaka comply with land use zoning? An analysis using nighttime light and digital building heights

Zoning is an important tool to regulate the use of land, characterize built form over land, and thus facilitate urban sustainability. Availability of reliable data is crucial for monitoring land use zoning, which contributes directly to the success of Sustainable Development Goals (SDGs) in general and SDG Goal 11 for sustainable cities and communities in particular.However, obtaining this valuable information using traditional survey methods is both costly and time-consuming. Remote sensing technology overcomes these challenges and supports urban policymaking and planning processes. This study unveils a novel approach to developing a cost-effective method for identifying building types using Sentinel-2A, Visible Infrared Imaging Radiometer Suite (VIIRS)-based nighttime light (NTL) data, and TanDEM-X-based Digital Surface Model (DSM) data. The newly developed Normalized Difference Steel Structure Index (NDSSI) is useful for rapidly mapping industrial buildings with steel structures.The implementation status of Dhaka's existing land use plan was evaluated by analyzing the spatial distribution of different types of building uses. This study classifies residential, commercial, and industrial buildings within Dhaka using building height, and nighttime light 2 emission. The experimental results reveal that about 67% of commercial and 51% of industrial buildings within the Dhaka Metropolitan Area (DMA) do not comply with the land use zoning by the Detailed Area Plan (DAP). It also reveals that approximately 10% of commercial buildings, 9% of industrial buildings, and 6% of residential buildings have encroached upon conservation zones (such as open space, flood prone zone, water bodies and proposed areas for future road extension). A major constraint in the study was the low spatial resolution of the nighttime lights dataset, which made it difficult to distinguish individual sources of light. Still, the methodological approaches proposed in this study are expected to promote reduced costs and efficacious decision-making in urban transformation and to help achieving SDG 11, especially in developing countries.

“…Dhaka is purposively selected as an area of study because it is the largest administrative, commercial, and industrial center and the capital of Bangladesh (Bahauddin et al 2014). A few rivers are located in Dhaka, such as the Buriganga, Turag, Tongi Khal, and Balu Rivers in its southwest, north, and east.…”

Flash floods are unexpected, localized flood events that occur when an exceptional amount of rain falls happens over a short period of time. In South Asia, it is mostly disastrous, for example, in 2017 flash floods killed approximately 1200 people from India, Nepal, and Bangladesh. However, it is also common in Dhaka megacity, Bangladesh due to its geographic location, monsoon climatic condition and surrounding rivers. Though it is impossible to avoid them, the losses and damages of hazards can be reduced effectively by using appropriate techniques. This study aims to determine the responsible factors and measure the household vulnerability to flash flood as a tool of mitigation. The study has been conducted based on primary data. Therefore, data were collected from both slum and non-slum population to cover the entire urban habitats. Data were collected with a structured questionnaire based on five factors (social, economic, institutional, structural, and environmental) of vulnerability to flash flood. The key feature of this paper is to provide an insight into real picture of vulnerability to flash flood for urban habitants. Moreover, this practical approach is useful to quantify hazard-induced vulnerabilities not only for Dhaka megacity but also for other cities of the globe.

“…The fieldwork for this study was conducted between July and August 2017, in Dhaka City. Elevated migration from rural areas, small towns and other cities in the country to the capital Dhaka has produced rapid population growth and territorial expansion of urban Dhaka (Bahauddin, Rahman, & Ahmed, 2014). These circumstances generate serious environmental and social challenges.…”

Waste pickers make a livelihood by collecting recyclable waste contributing to urban development and poverty reduction. Most often, they are socially excluded and exposed to different vulnerabilities (e.g. occupational health risks and accidents). This study adopts the sustainable livelihoods framework to assess multifaceted aspects of everyday life and work experiences of waste pickers in Dhaka, Bangladesh. The framework takes an integrated and transdisciplinary approach to livelihood assets and vulnerabilities. Our findings reveal a situation of extreme poverty and neglect of waste pickers, while they are making the city more sustainable. Specific policies, strategies and actions are required to reduce risks and improve the working conditions of waste pickers. © 2020 John Wiley & Sons, Ltd.
