Geospatial Tools to Tackle Public Health in Bangladesh

According to recent news published by the University of Texas at Dallas, Geospatial information sciences (GIS) can help determine where diseases are spreading and where to target the resources needed to stop them, but spatial data isn’t widely used for health decision-making in many developing countries.

The recently published UT Dallas study to identify — and ultimately remove — barriers to using GIS technology to solve public health problems in Bangladesh.

“Geospatial information sciences are still pretty new to some politicians and policymakers,” said Dr. Dohyeong Kim, associate professor of public policy and political economy and geospatial information sciences in the School of Economic, Political and Policy Sciences (EPPS). “They view it as something in academia. But GIS can be used as a tool to help inform decisions. We want to try to help them make more informed decisions.”

The study, published in the Journal of Health, Population and Nutrition, identified several issues that keep Bangladesh from fully adopting the use of spatial tools. They include a lack of collaboration between institutions, lack of trained personnel and lack of awareness of the use of geographic information systems in decision-making.

Bangladesh’s health system already collects the data necessary for GIS analysis, Kim said. The next step is to analyze and visualize the information to understand patterns and trends. Kim and co-author Priyanka Vyas, a PhD student in public policy and political economy, collaborated on the study with Dr. Malabika Sarker, professor at the James P. Grant School of Public Health at BRAC University in Dhaka, Bangladesh. The EPPS Advisory Council supported the research with a $5,000 grant that allowed Vyas to travel to Bangladesh to conduct surveys.

Bangladesh faces a range of public health concerns, including one of the world’s highest malnutrition rates. In addition, the densely populated country lies at a low elevation that leads to flooding and the spread of communicable diseases.

After Vyas’ trip to Bangladesh, Kim and Dr. Yongwan Chun, associate professor of geospatial information sciences, were invited to teach a workshop on geospatial analysis for health care in Bangladesh. The 2014 course was an important step, said Zabir Hasan, the senior research associate at BRAC who helped organize and participated in the event.

This research has created a connection that Kim hopes will lead to more UT Dallas projects to help expand the use of GIS. In late 2015, Kim and Chun created the Center for Geospatial Research in Global Health Policy to facilitate research and training in developing nations.
