Bangladesh turns 50 on 26th of March 2021. To celebrate this auspicious moment, we would like to present to our policymakers, development researchers, educators, and enthusiasts a web portal that endeavors to visualize Bangladesh from traditional and nontraditional data. Along with presenting various time series, correlational, map-based visualizations of traditional data we also present ranks of districts based on their most recent standing on specific indicators. The portal gives researchers and enthusiasts a chance to build composite indicators to capture the progress of living standards by varying weights of individual indicators, create their own rankings and clusters, and finally visualize them. We also present our ongoing research on non-traditional data sources to create potential alternative indicators for electricity consumption, land use, connectivity, and pollution.

The Daily Star has published an article “Policies without proper data are doomed to fail” by Dr. Amin Masud Ali and Dr. Moinul Zaber on July 22, 2020.
Dr. Moinul Zaber presented a keynote speech on Data and Design Lab’s recent works for energy policy at the Big Data and Power Management seminar organised by Bangladesh Energy Policy Research Council (BEPRC) on July 7, 2020. The seminar was presided over the Honorable Energy Advisor Dr. Tawfiq-e-Elahi Chowdhury, Honorable State Minister of Energy Nasrul Hamid and secretaries of high officials of energy ministries were present at the online seminar.
The focus of the keynote was the use of non-traditional data sources merging with traditional data sources to understand socioeconomic development and energy use of Bangladesh.
The presentation was based on our recent work on use of Nighttime lights data and household level electricity usage to understand people continously at disaggregated spatial spread.

A well-structured inland waterways system should help Bangladesh fulfill SDG goals. In this study, we employ complex network analysis methods to analyze the river-port network of the country. We ascertain different types of ports based on their importance and placement in the connectivity network. Data regarding port location, vessel routes, and schedules were collected from governmental resources. Using the data, a connectivity network was built for further analysis. Different measures of network analysis are used to categorize the ports and the network model has been identified. These categories should help transportation planners and policymakers to better design the inland waterways network of Bangladesh.

Analyzing the state and growth of various socio-economic indicators is essential for effective developmental planning at a sub-national level. However, in many cases, data regarding such indicators are not publicly available and/or hard to collect. In many other cases, the available data may not be recent enough. In contrast, satellite data is both readily available and up-to-date. In recent times, various studies have been conducted to use different types of satellite data as a proxy to determine the condition of socio-economic indicators in different places around the world. In this paper, we study the efficacy of one such data source, nighttime lights (NTL), for monitoring factors related to sustainable development in the context of Bangladesh.

Prepaid electricity meters are favored by power distribution companies to improve revenue collection, debt prevention and ensure customer satisfaction. In this paper, we investigate changes in bill payments pattern of customers in Dhaka, Bangladesh who had switched from post to pre-payment meters. We collected postpaid bill and prepaid recharge payment data over there years. We specifically look into payment behavior of residential household customers to understand the effect of prepaid meters on payment delinquency. Analysis of postpaid bill indicate that at least 32% households skipped paying one or more bills over a period of one year. Households consuming 100-300 KWH accounts for almost 51% of the total delinquent households. After prepaid switch, approximately 46% of all households are making prepayments every month. 52% of households who skip paying bill and 45% of households who pay bill after due date, at least once, are now recharging every month. Overall the technological intervention shows considerable reduction of retail debts and a behavioral shift towards on time payment.
