Thearea was planned and developed in the early fifties with large plots, wideroads and good environment. The main objective of the study is to makean investigation into the transformation of the this area with respect toland use, building height, intensity of land utilization (building coverageand FAR values), land-sub division and also the causes of the changes.From the study it is found that the non-residential uses are about 50% ofthe total; more than one fifth (21%) of the original one or two storeybuilding in Dhanmondi had been rebuilt to six storey apartment structures;the intensity of land utilization, in terms of building coverage increasedfrom 28.3% in 1962 to 50% in the year 2000; and the intensity of landutilization, in terms of FAR value increased from 0.39 in 1962 to 1.68 in theyear 2000. Present expansion of Dhaka City, more than six times biggerthan the Dhaka of the fifties, created demand for new spaces for new urbanactivities, and Dhanmondi gained location to the central part of the city.Transformation of the area is towards more intensive use of land; multi-storied apartments and non-residential uses. The non-residential uses havetaken place uncontrolled, unregulated and haphazard manner to thedetriment of the residential environment. Hence a revised plan ofDhanmondi has been urgent in order to control and regulate undesirabledevelopment in Dhanmondi for which a brief proposal is included in thestudy.

industrialization of Bangladesh have negative insinuations for water quality. The pollution from industrial, urban waste
effluents and from agrochemicals in some water bodies and rivers has reached apprehension levels these days in the
country. The marine and aquatic ecosystems are affected, and the chemicals that pierce the food chain have public
health implications. Maximum river water undergo alarming rate of pollution. Among the most polluted rivers in the
country, Buriganga in Dhaka city poses higher risk to the extensive environment. An average of 19 cubic liter water
containing more than 300 different chemical compounds is being discharged daily from surrounding industries of
Buriganga. The study entails river water pollution in Buriganga on the context of Bangladesh.

The spread of invasive alien plants is due to their opportunistic exploitation of anthropogenic disturbances; the absence of natural enemies; and frequently their allopathic competitive strategies. Invasive non-indigenous species can have a significant impact on development, affecting sustainability of livelihood, natural habitats, food security and rapidly changing the native character of indispensable natural or semi-natural ecosystem services and dynamics. The study entails the impact of these alien invasive plant species on the perspective of Bangladesh
