Cholera dynamics and El Niño-Southern Oscillation.

Analysis of a monthly 18-year cholera time series from Bangladesh shows that the temporal variability of cholera exhibits an interannual component at the dominant frequency of El Niño–Southern Oscillation (ENSO). Results from nonlinear time series analysis support a role for both ENSO and previous disease levels in the dynamics of cholera. Cholera patterns are linked.. Read More

Population pressure, environmental constraints and agricultural change in Bangladesh: examples from three agroecosystems

This study has examined the cultural ecology theory of agricultural change on the basis of a 40 year (1950–1990) temporal data set collected from 130 farmstead households living in three villages in Bangladesh. The villages represent xeric, wetland, and transformed irrigated rice agroecosystems. Owing to monsoon flooding and dry season shortage of water, both cropping.. Read More


Climate and infectious disease: Use of remote sensing for detection of Vibrio cholerae by indirect measurement

It has long been known that cholera outbreaks can be initiated when Vibrio cholerae, the bacterium that causes cholera, is present in drinking water in sufficient numbers to constitute an infective dose, if ingested by humans. Outbreaks associated with drinking or bathing in unpurified river or brackish water may directly or indirectly depend on such.. Read More

From nature-dominated to human-dominated environmental changes

To what extent is it realistic and useful to view human history as a sequence of changes from highly vulnerable societies of hunters and gatherers through periods with less vulnerable, well buffered and highly productive agrarian-urban societies to a world with regions of extreme overpopulation and overuse of life support systems, so that vulnerability to..

Vulnerability and Adaptation to Climate Change for Bangladesh

Avatar Image
  • Huq, et al.
  • 1999

This book is based on a substantial study carried out by a team of experts in different fields from Bangladesh, following a common (IPCC) guideline and with technical support from the US Country Studies Team. The study has for the first time developed scenarios for the impacts of climate change on agriculture and water sectors,.. Read More

Vulnerability of Forest Ecosystems of Bangladesh to Climate Change

Bangladesh is endowed with a number of natural forest ecosystems including inland Sal forest, dipterocarp forest, savanna, bamboo bushes in the hilly regions and freshwater swamp forests. It also have littoral mangrove ecosystems. An attempt was made to qualitatively analyse the impact of climate change on forest resources of Bangladesh. It was found that increased.. Read More


Beach Erosion in the Eastern Coastline of Bangladesh

Land loss due to beach erosion caused by sea level rise in the eastern coastline of Bangladesh was calculated by using Brunn’s formula. Estimation was done for three distinct areas: a) Bakkhali river valley b) Southern beach plain c) Nilla-Teknaf plain. In addition Moheskhali channel area was also studied. The slope of this coastline was.. Read More

Assessment of Foodgrain Production Loss Due to Climate Induced Enhanced Soil Salinity

The loss of foodgrain production due to soil salinity intrusion in the coastal districts was estimated under climate change scenarios. A computer model was developed that provided with a genesis of soil salinity build-up in the relatively drier months of the crop calendar. The time-series soil salinity database was compared with the field-level observations and.. Read More


Climate Change Vulnerability of Crop Agriculture

A simulation study was conducted to assess the vulnerability of foodgrain production due to climate change in Bangladesh. Two general circulation models were used for development of climate scenarios. The experiments considered impact on three high yielding rice varieties and one high yielding wheat variety. Sensitivity to changes in temperature, moisture regime and carbon-di-oxide fertilisation.. Read More

Water Resources Vulnerability to Climate Change with Special Reference to Inundation

Vulnerability of water resources considered changes in flooding conditions due to combination of increased discharge of river water during monsoon period and sea level rise for the two projection years, 2030 and 2075. MIKE11, a fixed bed hydrodynamic model, was used for the estimation of changes in river water level which was coupled with Geographic.. Read More
