Many of the world’s megacities depend on groundwater from geologically complex aquifers that are over-exploited and threatened by contamination. Here, using the example of Dhaka, Bangladesh, we illustrate how interactions between aquifer heterogeneity and groundwater exploitation jeopardize groundwater resources regionally. Groundwater pumping in Dhaka has caused large-scale drawdown that extends into outlying areas where arsenic-contaminated shallow groundwater is pervasive and has potential to migrate downward.
Freight transportation is a vital element for attaining sustainable development. Inefficient movement of goods does not only impend economic growth, but also results in various externalities such as air pollutants, greenhouse gas (GHG) and short-lived climate pollutants (SLCPs).
BRAC Institute of Governance and Development (BIGD), BRAC University has launched its annual flagship research report State of Cities (SoC) 2015 titled ‘Solid Waste Management in Dhaka City--Towards Decentralised Governance’. The study has captured constraints in addressing the city's solid waste problem.
Using the Climate Disaster Resilience Index (CDRI), this study measures climate disaster resilience of Dhaka City in its seven drainage zones - at ward and thana level. The analysis provides a wealth of information that can be used to identify priority sectors in Dhaka for improving disaster resilience.
Environmental enteropathy (EE) is a subclinical enteric condition found in low-income countries that is characterized by intestinal inflammation, reduced intestinal absorption, and gut barrier dysfunction. The researchers aimed to assess if EE impairs the success of oral polio and rotavirus vaccines in infants in Bangladesh.
Dhaka, the capital of Bangladesh and one of the world’s rapidly growing megacities, is an urban hotspot for climate risks. Located in central Bangladesh on the lower reaches of the Ganges-Brahmaputra Delta, the city faces the recurring phenomena of urban flooding and waterlogging following intense rainfall nearly every year.
