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..

  • 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

Climate change impacts and adaptation assessment in Bangladesh

Bangladesh is likely to be one of the most vulnerable countries in the world to climate change. This paper discusses the possible impacts of climate change in Bangladesh through tropical cyclones, storm surges, coastal erosion and back water effect. The possible increase in cyclone frequency in the Bay of Bengal, lying south of Bangladesh, due.. Read More

Weathering processes in the Ganges-Brahmaputra basin and the riverine alkalinity budget

We present river chemistry data for a network of rivers draining the western and central Nepal Himalaya. Our sampling locations cover the system from the sources of rivers in Tibet to the Gangetic plain. Water samples were collected throughout the year, including the monsoon season, for rivers in Nepal and for the Ganges and Brahmaputra.. Read More

Thermal Climate Variations and Potential Modification of the Cropping Pattern in Bangladesh

Changes in the thermal climate due to inter-annual climatic variability can potentially modify existing cropping pattern by forcing farmers to rearrange transplanting and harvesting dates. In the present study, a crop climate model, the YIELD, has been applied to 12 meteorological stations located in major rice growing regions in Bangladesh to estimate the effect of.. Read More

Population and environment in Bangladesh

  • Huq, et al.
  • 1998

The paper challenges the simplistic concept of population as an aggregate of consuming units, putting stress increasingly on the natural resources leading to environmental degradation. It argues that the inter-relationship between population and environment is more complex and multi-dimensional. Human beings are not always consumers they are also producers and some time they are conservators.. Read More

Simulating the impact of climate change on rice production in Asia and evaluating options for adaptation

The likely effects of climate change caused by increasing atmospheric carbon dioxide levels on rice production in Asia were evaluated using two rice crop simulation models, ORYZA1 and SIMRIW, running under ‘fixed-change’ climate scenarios and scenarios predicted for a doubled-CO2 (2 × CO2) atmosphere by the General Fluid Dynamics Laboratory (GFDL), the Goddard Institute of..
