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 synergistic effects between systems components that result in efficient resource use and enhanced production, whilst avoiding negative environmental impacts. Integrated cropping.. Read more

  • , et al.
  • 2017

The study was conducted to investigate the impacts of Brahmaputra riverbank erosion hazard on livelihood pattern of char people, agriculture and environment. Five villages of Mymensingh district near to the Brahmaputra River were selected. A semi-structured questionnaire, interview, secondary data sources, field observation and focus group discussion were utilized for this study. Result revealed that.. Read More

Adaptibility of tomato genotypes suitable for coastal region of Patuakhali in Bangladesh

  • , et al.
  • 2017

A field experiment was carried out at the Regional Horticultural Research Station, Lebukhali, Patuakhali, during the winter. The experiment was conducted to find out adaptive tomato genotypes suitable for coastal Patuakhali region considering their growth and yield performance. The genotypes of this experiment showed significant influence independently on different parameters of tomato plant. The maximum.. Read More

Adaptation to climate change in agriculture in Bangladesh: The role of formal institutions

Bangladesh is very vulnerable to the impacts of climate change, and adaptation is emerging as a key policy response. Place based programs that build adaptive capacity are needed. This paper explores the effectiveness of formal institutions in climate change adaptation for agriculture from the perspectives of farmers and institutional communities of practice within two drought-prone..

Salinization and arsenic contamination of surface water in southwest Bangladesh

To identify the causes of salinization and arsenic contamination of surface water on an embanked island (i.e., polder) in the tidal delta plain of SW Bangladesh we collected and analyzed water samples in the dry (May) and wet (October) seasons in 2012–2013. Samples were collected from rice paddies (wet season), saltwater ponds used for brine.. Read More

Non-economic losses from climate change: opportunities for policy-oriented research

The concept of non-economic losses (NELs) has recently emerged in the context of negotiations on loss and damage under the United Nations Framework Convention on Climate Change (UNFCCC). NELs are losses of values that are not commonly traded in markets but bear high relevance for those affected. Examples include loss of life, biodiversity and cultural.. Read More

Time evolution of atmospheric parameters and their influence on sea level pressure over the head Bay of Bengal

A zonal dipole in the observed trends of wind speed and significant wave height over the Head Bay of Bengal region was recently reported in the literature attributed due to the variations in sea level pressure (SLP). The SLP in turn is governed by prevailing atmospheric conditions such as local temperature, humidity, rainfall, atmospheric pressure,.. Read More

Benchmarking pre-spawning fitness, climate preferendum of some catfishes from river Ganga and its proposed utility in climate research

The concept of threshold condition factor (Fulton), beyond which more than 50% of the female fish population may attain readiness for spawning coined as pre-spawning fitness (Kspawn50), has been proposed in the present article and has been estimated by applying the non-parametric Kaplan-Meier method for fitting survival function. A binary coding strategy of gonadal maturity stages was.. Read More

Long-term impact of changing childhood malnutrition on rotavirus diarrhoea: Two decades of adjusted association with climate and socio-demographic factors from urban Bangladesh

  • Das, et al.
  • 2017

There is strong association between childhood rotavirus, diarrhoea, climate factors and malnutrition. Conversely, a significant nutritional transition (reduced under-nutrition) with a concurrent increasing trend of rotavirus infection in last decade was also observed among under 5 children, especially in developing countries including Bangladesh. Considering the pathophysiology of rotavirus, there might be an interaction of this.. 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..
