Future changes in water requirements of Boro rice in the face of climate change in North-West Bangladesh

Understanding future changes in crop water requirements and irrigation demand in the context of climate change is essential for long-term water resources management and agricultural planning. This study investigates the impacts of climate change on future water requirements of dry season Boro rice. Climate scenarios for four North-West districts of Bangladesh were constructed from the outputs of five global circulation models using a combination of statistical downscaling and bias correction. The generated climate data were used as input for CropWat to estimate water requirements.. Read more

Evaluating the contribution of diversified shrimp-rice agroecosystems in Bangladesh and West Bengal, India to social-ecological resilience

Shrimp-rice farming practices in the coastal areas of Bangladesh and West Bengal, India are reviewed. It is apparent that this integrated aquaculture-agriculture system is suited to environmental and hydrological conditions found in specific areas. Production strategies devised by farmers demonstrate that the diversified culture of shrimp with rice is technically feasible. Shrimp-rice agroecosystems exhibit several.. Read More

Gender, Climate Change, and Sustainable Development in Bangladesh

Climate change has become one of the most important global development issues in the current global political context. The impact of a changing climate is witnessed daily across nations north and south as a result of industrialization, greenhouse gas emissions, deforestation, fossil fuel burning, and other human activities (Mignaquy, Gender perspectives on climate change, 2014: 3)… Read More

Assessing irrigation water quality in Faridpur district of Bangladesh using several indices and statistical approaches

Several water quality indices, i.e., salinity hazard (SH), sodium percentage (Na%), sodium adsorption ratio (SAR), permeability index (PI), magnesium hazard (MH), Kelly’s ratio (KR) and irrigation water quality (IWQ) indices are applied to assess the irrigation water quality using 60 groundwater samples collected from the study sites. This study reveals that groundwater samples are mainly.. Read More

Performance of rain-fed Aman rice yield in Bangladesh in the presence of climate change

This paper uses the framework of the Just–Pope production function to evaluate the impacts of climate change on yields of the rainfed Aman rice crop in Bangladesh. It analyses disaggregated district-level data on climate variables and Aman rice yield over a 48 year time horizon. The results reveal that changes in maximum temperatures have had.. Read More

Extreme flows and water availability of the Brahmaputra River under 1.5 and 2 °C global warming scenarios

The recently reached Paris Agreement at the 21st Conference of the Parties (COP21) of the United Nations Framework Convention on Climate Change (UNFCCC) in 2015 includes a goal of pursuing efforts to limit the global warming at 1.5 °C. Following this, the Intergovernmental Panel on Climate Change (IPCC) has accepted an invitation by the UNFCCC to.. Read More

Characterizing groundwater quality ranks for drinking purposes in Sylhet district, Bangladesh, using entropy method, spatial autocorrelation index, and geostatistics

Drinking water is susceptible to the poor quality of contaminated water affecting the health of humans. Thus, it is an essential study to investigate factors affecting groundwater quality and its suitability for drinking uses. In this paper, the entropy theory, multivariate statistics, spatial autocorrelation index, and geostatistics are applied to characterize groundwater quality and its.. Read More

Evaluation of water quality for sustainable agriculture in Bangladesh

Sustainable groundwater quality has become a major concern for the agro-based country like Bangladesh. Integrated approaches of various irrigation water quality indices and geostatistical modeling were applied to evaluate the suitability and for spatial mapping of groundwater quality of Faridpur District in central Bangladesh. The irrigation water quality index (IWQI) revealed that majority of the.. Read More

Disruption, not displacement: Environmental variability and temporary migration in Bangladesh

Mass migration is one of the most concerning potential outcomes of global climate change. Recent research into environmentally induced migration suggests that relationship is much more complicated than originally posited by the ‘environmental refugee’ hypothesis. Climate change is likely to increase migration in some cases and reduce it in others, and these movements will more.. Read More

Integrated coastal resources management of Saint Martin’s Island, Bangladesh

Coastal ecosystems support enormous natural resources which are major sources of livelihoods and income generation for a major part of the global population. With this growing dependency coupled with the continued destruction (from both global climate change and human interventions), coastal resources are facing unprecedented threats of deterioration thus limiting the valuable ecosystem services that..
