The present paper aimed at identifying microclimatic variations in Dhaka city and is based on the noon and evening air temperature and relative humidity of four study sites in Dhaka city. It reveals statistically significant differences of air temperature and relative humidity. Motijheel, the commercial heart of Dhaka City has the highest average temperature at noon (12 pm: 29.0°C) and at evening (6pm: 27.3°C). Little variation of relative humidity is seen among the areas at noon (12pm). All the areas have 49% mean relative except Agargaon’s Bangladesh Meteorological Department’s weather station where relative humidity reaches 44%. In the evening this variation becomes significant as in Motijheel and Segunbagicha-Kakrail area mean relative humidity remain below 60% and in Dhaka University Area and Agargaon, BMD it reaches above 60% .Motijheel area has the lowest mean air temperature range (1.7°C) and mean relative humidity range 8%. These evidences bring the testimony of urban microclimatic condition and worsening heat environment in Dhaka city.

Bangladesh faces multiple manifestations of climatic change and is one of the most vulnerable countries in the world. The study was carried out based on secondary information to assess the temperature trend in Dhaka city. The study revealed that average annual and seasonal temperature in Dhaka city is in an increasing trend during last couple of decades. From 1950s to 1960s average annual temperature was remained stable (25.10C) which is 0.60C lower than baseline temperature (25.70C). Then, temperature increased gradually (25.40C in 1970s and 25.80C in 1980s). During 1990s annual temperature remained stable but it was 0.10C higher than the baseline temperature. However, during 2000s annual temperature increased 0.20C which is 0.30C higher than the baseline temperature. Proper mitigation plans and adaptation policies are inevitable to minimize the impacts of climate change.

Much attention has been focused on ship breaking industries in the coastal areas because of the threat they pose to this thriving biological industry along with their other environmental impacts and the perilous working environment of the workers. The coastal environment of Sitakunda is severely contaminated by various processes related to ship-breaking i.e. the disposal of different toxic wastes into the sea water, deforestation by expanding ship breaking yard, changing landuse pattern and release of toxic substance into the soil. Moreover, the workers of this industry are exposed to extremely risky and toxic working environment which makes them vulnerable to both physical and psychological disorder as well as accidental deaths and injury. Still, the workers embrace these risk for very poor wages and most of the profits goes to the already reach businessmen. Despite various negativities, this industry has gained importance due to the increasing demand of raw material for re-rolling industries and employment opportunities for the people of the coastal areas. As this industry is indispensable due to its importance in the macro and micro economy of Bangladesh, a sustainable management approach should be taken to at least minimize the environmental and health impacts of ship breaking industries. The current paper aims to investigate the extent to which this industry is affecting the labors and the environment, despite the growing concern nationally and internationally and it used both primary and secondary data.
