Assessment of arsenic health risk and source apportionment of groundwater pollutants using multivariate statistical techniques in Chapai-Nawabganj district, Bangladesh

This study assessed arsenic health risk to the local residents through oral and dermal exposure pathways of drinking water and to investigate source apportionment of groundwater pollutants using multivariate statistical techniques in the Chapai-Nawabganj district, Bangladesh. Groundwater samples collected from shallow tube well and dug well at the depth ranges (15-60 m) were analyzed for.. Read More

Flood Maps and Bank Shifting of Dharla River in Bangladesh

Bangladesh is prone to severe flooding as being located at the confluence of three mighty rivers named the Ganges, Brahmaputra, and Meghna. As a consequence, river flooding and erosion are common natural disasters that severely affect the landscape, lives and economy of the country. Dharla River, one of the trans-boundary rivers originated in the Himalayas,.. Read More

Stepped-wedge cluster-randomised controlled trial to assess the cardiovascular health effects of a managed aquifer recharge initiative to reduce drinking water salinity in southwest coastal Bangladesh: study design and rationale

Saltwater intrusion and salinisation have contributed to drinking water scarcity in many coastal regions globally, leading to dependence on alternative sources for water supply. In southwest coastal Bangladesh, communities have few options but to drink brackish groundwater which has been associated with high blood pressure among the adult population, and pre-eclampsia and gestational hypertension among..

An assessment of vulnerability and adaptation to cyclones through impact assessment guidelines: a bottom-up case study from Bangladesh coast

After reviewing relevant climate impact assessment guidelines derived from those of the United States Country Study Program (USCSP), the Intergovernmental Panel on Climate Change (IPCC) and UNEP, the author adopted a set of impact assessment steps towards a methodological procedure for assessing vulnerability and adaptation (V and A) in a Bangladesh coastal cyclone-prone area. This.. Read More

Farmers’ perceptions of and responses to environmental change in southwest coastal Bangladesh

Coastal Bangladesh is highly vulnerable to climate change and salinisation; hence, farm-level adaptation is critically important. Farmers’ perceptions of and responses to environmental change were investigated in two villages in Khulna District. Perceived environmental trends included increases in temperature, extreme weather events, soil toxicity, erratic rainfall and scarcity of water for irrigation. Perceptions of climate.. Read More

Remote sensing and GIS for the spatio-temporal change analysis of the east and the west river bank erosion and accretion of Jamuna river (1995-2015), Bangladesh

Jamuna River is one of the principal rivers of Bangladesh, changing continuously due to erosion and accretion over the past decades. This analysis evaluates the East Bank and the West Bank erosion and accretion between 1996 and 2015 for Jamuna River. An unsupervised classification algorithm and post-classification change employing skills in Geographic Information System are.. Read More

Evaluation of the environmental impacts of rice paddy production using life cycle assessment: case study in Bangladesh

The world is heading towards sustainability. Environmental dimension of sustainability is getting momentum and therefore it is imperative to know the peril through environmental load of a product, process, or activity throughout its life cycle. This study focuses on life cycle assessment (LCA) of rice production in Bangladesh, the fourth highest producer of rice in.. Read More

Differential livelihood adaptation to social-ecological change in coastal Bangladesh

Social-ecological changes, brought about by the rapid growth of the aquaculture industry and the increased occurrence of climatic stressors, have significantly affected the livelihoods of coastal communities in Asian mega-deltas. This paper explores the livelihood adaptation responses of households of different wealth classes, the heterogeneous adaptation opportunities, barriers and limits (OBLs) faced by these households..

Wheat production and consumption dynamics in an Asian rice economy: The Bangladesh case

Wheat consumption in Asia’s major rice economies has been increasing over the decades. Bangladesh is no exception, despite being the world’s fourth largest rice-producing and the largest rice-consuming country. In Bangladesh, wheat consumption has doubled from 1961 to 2013, and now stands at 17.5 kg per capita, about a ninth of the rice consumption. Densely populated.. Read More

Does resilience capacity reduce the negative impact of shocks on household food security? Evidence from the 2014 floods in northern Bangladesh

Using data collected before and after the catastrophic flooding that took place in northern Bangladesh in 2014, this paper contributes to the growing evidence on the factors enhancing households’ resilience to shocks, or their “resilience capacities”. The analysis takes into account all three dimensions of resilience capacity—absorptive, adaptive, and transformative—as well as a broad range.. Read More
