Shipbuilding in Bangladesh has been considered as the most promising industry in the recent time and the country is dreaming to emerge as a middle income country within a short time by maintaining the upward trend of this sector. However, due to global nature and the long term sustainability of this shipbuilding industry, an investigation of competitiveness in terms of global standard is of prime importance. this paper focuses on studying some crucial competitive factors like labor skill, labor availability, labor man-hour, labor cost ＆ productivity for local shipbuilding in Bangladesh. the analysis also focuses on existing access to the resources like m.t.rials, knowledge and capital which are equally important factors for the expansion of shipbuilding. Comparison of these param.t.rs with other nations have been made qualitatively and quantitatively to find the level of our shipbuilding. On the basis of existing condition and future vision, some recommendations have been made which might be useful for accelerating the development of this sector.

Bangladesh enjoys food self-sufficiency or deficiency depending on crop damages by drought, floods, cyclones, storm.t.dal surges and other natural hazards. Data on clim.t. extremes were collected from literatures. Landsat images were analyzed for water availability. Arithm.t.c, geom.t.ic and weighted means were calculated for community vulnerability delineation using IDRISI3.2. About 12.64% populations live in disaster prone areas and their sensitivity to exposed hazards depends on financial capabilities. Crop area damages by natural hazards were the highest in Dhaka division followed by Rajshahi division during 2009-2014. the highest economic loss ($613 million) was found in Barisal division followed by Dhaka ($198.7 million) division. Flooding was the most damaging clim.t. extreme followed by drought and hailstorm. Rice crops are frequently exposed to clim.t. extremes and caused economic loss of $228 million during 2009-2014. Economic losses were to 1,000 ha-1 because of wheat/maize areas damaged by natural hazards. the most vulnerable areas are situated in the south-west and north-west part of the country. the most affected areas (35.4% of the country) had economic losses of $940-1,170 ha-1. About 2-4.7 million households (HH) were affected by different natural hazards in different regions of the country. Flood affected HHs were predominant in northern and north-east regions of the country. Common adaptations to natural hazard exposures are crop switching and migration. the other adaptation options could be improvement of post disaster recovery efficiency through financial support, supplying seeds and other inputs based on seasonal suitability.

Element Composition of the Atmospheric Depositions in Bangladesh

引用

Journal of Environmental Protection 2018年第9期9卷 948-956页

作者： Jatish Chandra Biswas md mozammel Haque mahmuda Akter A. t. m. Sak.a.at hossain Faruk hossain k.a. md zakaria Ibne Baki Abu Bakar Siddique Sarker md Rafiqul Islam Bangladesh Rice Research Institute Gazipur Bangladesh

Compositions of dry and wet atmospheric depositions vary depending on geographic locations and industrialization. Fog waters were collected from different regions of Bangladesh along with rain, sub-surface irrigation water and dust particles from gazipur and compositions were analyzed. the compositions of fog water varied greatly among locations. the ammonium nitrogen (nH+4-n) content was the highest (36 - 37 ppm) in gazipur district and the lowest in Sylhet district (3.2 - 3.6 ppm). Phosphorus (5.2 - 5.5 mg/L), k (29.5 - 30 mg/L), S (11.0 - 11.5 mg/L), Zn (2.9 - 3.3 mg/L), na (11.7 - 12.5 mg/L), Ca (22.0 - 23.3 mg/L) and Cd (0.14 - 0.17 mg/L) contents were also higher in gazipur district. Dust particles, rain and sub-surface irrigation water of gazipur district contained considerable amounts of macro and micro elements. We conclude that dry and wet atmospheric depositions varied depending on locations and industrial development. Such study needs to be correlated with ecological consequences and soil fertility management.
