Water quality and Sanitation status: A study on Char land of Bhuapur upazila under Tangail district

The study was aimed to review the damage of sanitation facilities; since Char land’s dwellers faces manifold challenges concerning sanitation, hygiene and water during flood. It also explored the possibilities of overcoming the negative impacts of floods on sources of safe drinking water and sanitation. The study result shows that, about 54% of the overall latrines were included ring slab with water seal, pit latrine, bush or hanging toilet of the flood affected people during the flood. Around 19% of the respondents use to do toilet in the open area during flood. Different NGOs e.g. Jamuna Char Development Project (JCDP), Bangladesh Rural Advancement Committee (BRAC), CARE and Red Crescent Society of Bangladesh works for rehabilitation of the flood affected people and give early warning on the flood. Depending on location and sanitation conditions, drinking water sources may be contaminated by flood water during flood and many waterborne diseases can spread out like Cholera, Dysentery, Diarrhoea, diseases of the skin, Typhoid etc. meantime. The conducted survey also reports that, drinking water and sanitation condition is not dependable (on the commentary of 64.8% of the responders). Therefore, the flood affected people of Bhuapur are usually underprivileged from appropriate sanitation facility on flood. They somehow conform themselves while a chain of problems strikes hardly during flood

Effects of climate change on rice production at Khulna District, Bangladesh

In Bangladesh 164 million people depend on rice but due to climate change (CC) vulnerabilities the yield of rice is severely reducing. Therefore, this study aimed to explore the effects of CC on rice yield using recent trend analysis, Mann-Kendall (MK) trend test and correlation. For this study, the required climate and selected rice production data were collected from Bangladesh Meteorological Department (BMD) and Department of Agriculture Extension (DAE), Khulna. In time series statistics both parametric and nonparametric methods were applied to detect a monotonic trend of climatic variability and Aman rice production. Correlation between climatic variability and rice production was also investigated. The study exposed that the temperature and rainfall had an increasing trend and statistically significant whereas the relative humidity found decreasing. Overall, the bright Sunshine had positive trend but week. According to nonparametric trend test of climatic variability and Aman yield only minimum temperature showed a positive trend which found statistically significant. In contrast, Mann-Kendall trend test revealed that rainfall had positively significant while temperature had negative significant. The correlation revealed the Aman production is a strong response with minimum temperature whereas the Lona Coche showed a positive correlation with maximum temperature. The variation of Aman production exhibited a positive correlation with both Rainfall and humidity respectively and Lona Coche found a negative correlation. The sunshine had a week correlation against both yields. The findings suggest should give attention of temperature-tolerant rice varieties to mitigate possible adverse effects of CC
