River bank erosion is a natural process that occurs when the water flow of a river exceeds the bank’s ability to withstand it. It is a common phenomenon that causes extensive land damage, displacement of people, loss of crops, and infrastructure damage. The Gorai River, situated on the right bank of the Ganges, is a significant branch of the river that flows into the Bay of Bengal via the Mathumati and Baleswar rivers. The erosion of the banks of the Gorai River in Kushtia district is not a recent occurrence. Local residents have been dealing with this issue for the past hundred years, and according to the elderly members of the community, the erosion has become more severe activities. Therefore, the main objective of this research is to quantify river bank erosion and accretion and bankline shifting from 2003 to 2022 using multi-temporal Landsat images data with GIS and remote sensing technique. Bank-line migration occurs as a result of the interplay and interconnectedness of various factors such as the degree of river-related processes such as erosion, transportation, and deposition, the amount of water in the river during the high season, the geological and soil makeup, and human intervention in the river. The results show that the highest eroded area was 4.6 square kilometers during the period of 2016 to 2019, while the highest accreted area was 7.12 square kilometers during the period of 2013 to 2016. However, the erosion and accretion values fluctuated from year to year.

This research project investigates the current status of water supply, sanitation, and hygiene practices in Munshiganj District, Bangladesh. Data collection involved a structured questionnaire and a reconnaissance survey. Findings reveal that 30% of individuals rely on surface water (hand-tube wells, rivers, and ponds), prioritized as canal > river > pond, while 70% depend on groundwater (subterranean electric motor, deep tube-well). Drinking water is generally sufficient, with 95% reporting adequacy throughout the year. About 45% use hand tube-well water, 28% use deep tube-well water, and 11% use supply tap water for various purposes. Bathing trends include underground water through electric motor > pond > hand tube-well water > river, while for cooking, the order is underground water through electric motor > pond > hand tube-well water > river. Toilet water supply ranks as supply tap water > hand tube-well water > deep tube-well water. Although sanitation awareness is high, some lack knowledge of good hygiene practices. After defecating, handwashing methods include soap, ash, soil, or water. Children’s waste disposal varies, with some discarding it in open areas. Approximately 40% suffer from diseases like Diarrhoea due to unsafe water, primarily affecting children and elders. Training exists, but a significant portion lacks sanitation education. Dry skin or exposure to cold water may cause temporary irritation. Local government involvement in sanitation efforts is less active compared to non-governmental organizations. Results emphasize the need to enhance community awareness of safe water supplies and sanitation practices. .

外商直接投资对南盟国家经济增长的影响研究

外商直接投资对南盟国家经济增长的影响研究

外商直接投资(FDI)对于任何国家的经济发展都是一个重要因素。FDI影响国民经济增长率的因素有很多。当FDI进入东道国时,会产生大量的商业机会。东道国员工就业机会也会随之增加,从而降低失业率,最终会提高其国内生产总值的增长率。通过获得外资,企业可以将业务拓展到世界各地,不同领域的基础设施也会得到发展,所有这些因素都会影响经济的扩张。因此,本文进行了研究以确定FDI对南亚区域合作联盟国家经济增长的影响。本文首先分析了南盟国家FDI和经济增长的现状特点。研究发现南盟国家的FDI和国内生产总值增长各不相同。印度的FDI在2020年达到646.6亿美元的峰值,然后下降。2022年,孟加拉国和阿富汗的FDI分别增加至15.6亿美元和130亿美元。而斯里兰卡、巴基斯坦和尼泊尔分别降至10.8亿、13.4亿和950亿美元,不丹和马尔代夫几乎没有FDI。此外,南盟各国的国内生产总值增长差异很大,反映了经济困境和复苏。然后,从直接影响和间接影响两个方面,理论分析了FDI对经济增长的影响。研究发现,FDI可以直接造成资本冲击,并通过影响其他经济因素间接影响东道国经济增长。FDI将直接或间接增加出口,弥补发展中国家进口资金短缺,建立外部经济平衡。接着,采用2013-2022年的数据,选取出口规模、进口规模、通货膨胀率和失业率作为控制变量,运用最小二乘法(OLS)、随机效应模型、固定效应模型和可行广义最小二乘法(FGLS)等实证方法分析了FDI对南盟国家经济增长的影响。通过实证结果发现,FDI会对南盟国家经济增长产生显著的正向影响,FDI规模越大,经济增长率越高。因此,可以说FDI是国民经济增长率的重要贡献者。最后,根据以上分析,得到如下政策启示:东道国需要简化各种类型的监管要求,以便设立和经营企业;采取保护措施,解决外国投资者在法律问题和争端方面的各种担忧;加强职业培训和适当的教育,培养适应能力强、熟练的劳动力;提供一些税收激励和免税政策;改善产业结构,提高人力资本水平,增强竞争力;为了更好地吸引FDI,政府需要进一步扩大向外界开放的经济部门,提高整体经济的国际化水平。

A trial ofAvicennia officinalis L. with five different spacings was conducted in the newly accreted lands along the western coastline （Patuakhali district） of Bangladesh since 1993 to assess growth perform- ance and the effect of spacing on tree growth. Data on tree density, height, diameter, bole height, crown diameter were recorded and ana- lyzed when the stand was 19 years old. Mean height ranged from 12.89-13.52 m and diameter at breast height （dbh） from 26.57-32.16 cm in plots of different spacings. The mean annual height increment ranged from 0,67-0.71 m, mean annual diameter increment from 1.40-1.69 cm and wood volume from 6.02-10.04 ***＇*** in different treatments. Significantly greater diameter （32.16 cm） and wood volume （10.04 ***.a-1） were obtained with wider （2.13 m × 2.13 m） spacing than with closer spacings. But tree growth was unaffected by other spacings. Growth data were also recorded from other .4. officinalis plantations raised by Forest Department （FD） on different islands in Patuakhali and Bhola districts of Bangladesh. At these sites, mean annual height incre- ment ranged from 0.33-0.62 m, mean annual diameter increment from 0.72-1,37 cm and wood volume from 1.55-5.73 m3·ha-1·a·-1. The growth performance of A. offindicated that the newly aecreted lands along the western shoreline may be suitable for raising Avicennia planta- tions for the enrichment of coastal vegetation.
