On shrimp,salt and security: livelihood risks and responses in South Bangladesh and East India

Bangladesh and India are among the world’s most populous but also most vulnerable countries to environmental risks. In addition to storms, sea-level rise, floods and droughts, local communities face a multitude of pre-existing and concomitant economic and socio-political risks. To understand these risks and how communities respond to them is critical in securing community livelihoods. We therefore ask what are the livelihood risks; how do they impact the human security of environment sensitive communities in Satkhira, Bangladesh and in Odisha, India; and, what are the responses of these communities to the livelihood risks? The communities studied in Bangladesh depend mainly on the shrimp and fish resources of the Sundarbans mangrove forest. The two communities researched at Lake Chilika in India depend on fishing and salt farming, respectively. The field research, conducted in 2012 and 2013, shows that the communities face multiple and interacting livelihood risks. While storms and floods are common environmental risks in both countries, related livelihood risks are case-specific. In Bangladesh, attacks by criminals are the major threat to human well-being, while in India, it is violent conflict between lake users. Unsustainable resource extraction is found in both study countries. In Bangladesh, shrimp farming weakens the flood protection, while in India, illegal prawn farming marginalizes poorer lake users. Accessing loans and labor migration are responses observed in both countries. We conclude that adaptation to environmental changes needs to be sensitive to the interaction between governance, local institutions and socio-economic developments.

Prenatal diagnosis of vascular anomalies

Vascular anomalies are rare disorders that encompass a group of lesions characterized by abnormal development of the lymphovascular system. Majority of these anomalies are present at birth and could potentially be detected during the prenatal period on imaging. This allows for early intervention and prompt management to improve outcomes. However, they can be difficult to diagnose, given the rarity and overlapping findings. In this review article, we provide a comprehensive overview of congenital vascular anomalies with a liberal use of images of recent cases at our center emphasizing prenatal imaging findings and the natural history of these conditions.     

Development of a new approach for microbial decontamination of water using modified Fenton's reaction

Microbial decontamination of water was carried out using a novel radical generating system consisting of ion exchange resin, copper and hydrogen peroxide. The system was successful in reducing the microbial load in water by more than 99% in 15 min and is effective against all the microorganisms tested. The method was also successful in decontaminating the flood water obtained from Industrial Canal and 17th Street Canal in New Orleans. Decontamination is due to the formation of hydroxyl radicals, formed during the decomposition of hydrogen peroxide by the metal-polymer complex.
