El Niño and health

El Niño Southern Oscillation (ENSO) is a climate event that originates in the Pacific Ocean but has wide-ranging consequences for weather around the world, and is especially associated with droughts and floods. The irregular occurrence of El Niño and La Niña events has implications for public health. On a global scale, the human effect of.. Read More

Mainstreaming adaptation to climate change in least developed countries (LDCs)

Adaptation to climate change has become an important policy priority in the international negotiations on climate change in recent years. The experience cited in this report on two LDC countries, namely Bangladesh in Asia and Mali in Africa, shows that although much has been achieved in terms of describing and analysing vulnerability to climate change..

The Implications of Climate Change on Floods of the Ganges, Brahmaputra and Meghna Rivers in Bangladesh

Climate change in the future would have implications for river discharges in Bangladesh. In this article, possible changes in the magnitude, extent and depth of floods of the Ganges, Brahmaputra and Meghna (GBM) rivers in Bangladesh were assessed using a sequence of empirical models and the MIKE11-GIS hydrodynamic model. Climate change scenarios were constructed from.. Read More

Mineralogy of the Ganges and Brahmaputra Rivers: implications for river switching and Late Quaternary climate change

Late Quaternary sediments of the Bengal basin contain a history of river switching and climate change as revealed from sand- and clay-size mineralogy of boreholes and modern riverbed grabs. Epidote to garnet ratios (E/G) in sand fraction sediments are diagnostic of source, with high (>1) E/G indicating Brahmaputra provenance and low (<1) E/G indicating Ganges.. Read More


Controls on facies distribution and stratigraphic preservation in the Ganges-Brahmaputra delta sequence

Abundant sediment supply and accommodation space in the Bengal Basin have led to the development of a major Late Quaternary delta sequence. This sequence has formed in a tectonically active setting and represents an important example of a high-energy (marine and fluvial), high-yield continental margin deposit. Recent studies have detailed the delta’s stratigraphy and development,.. Read More

Regional Cooperation in Flood Management in the Ganges-Brahmaputra-Meghna Region: Bangladesh Perspective

Bangladesh is known to be highly vulnerable to floods. Frequent floods have put enormous constraints on its development potential. Unfortunately, the frequency of high intensity floods is on the rise. So far the country has struggled to put a sizeable infrastructure in place to prevent flooding in may parts of the country with limited success… Read More

Alleviate or adapt? How can the south prepare for climate change?

The least developed countries (LDCs) may be contributing the least to emission of greenhouse gases but they are the most vulnerable to climate change. Can national development policies include adaptation to the anticipated unfavourable impacts of climate change? What lessons can be learnt from LDCs that have begun planning their long- term adaptive capacity?

Children’s environmental health: risks and remedies

This policy brief (part of PRB’s Emerging Policy Issues in Population, Health, and Environment series) explores children’s special vulnerability to environmental hazards such as smoke from traditional fuels and from emerging risks such as exposure to an increasing number of hazardous chemicals. The brief outlines the risks and the conditions that increase such risks, and.. Read More


Mineralogical changes during intense chemical weathering of sedimentary rocks in Bangladesh

Bangladesh is situated in a subtropical to tropical climatic zone. A recently weathered crust has developed on sedimentary bedrock (sandstone, siltstone, shale and claystones) of Tertiary-Quaternary age. Weathered samples were collected from 16 sections totaling 68 samples and were analyzed mineralogically. The main primary minerals identified in the weathered crust of sedimentary rocks are quartz,..

Global warming and changes in the probability of occurrence of floods in Bangladesh and implications

Bangladesh is very prone to flooding due to its location at the confluence of the Ganges, Brahmaputra and Meghna (GBM) rivers and because of the hydro-meteorological and topographical characteristics of the basins in which it is situated. On average, annual floods inundate 20.5 per cent area of the country and this can reach as high.. Read More
