Abstract
Urban forestry and urban greening is one of the most substantial factors for sustainable urban development, which can contribute towards good quality of life and sound environment. Dhaka, the capital of Bangladesh once renowned for its green resources but in recent times the city is losing its greeneries very rapidly. This study was intended to explore the status of urban greening as well as to investigate the prospects and challenges for enhancing urban forestry and urban greening in Dhaka North city corporation area (Zone-1). This study focused on the qualitative approach where interview with key informants, questionnaire survey and observation techniques were followed to obtain required information. The study identified some factors that are responsible for losing of green resources in Dhaka city including transformation of existing green areas or open spaces to other land use purposes, unplanned urbanization & improper planning, rapid increase of urban population and lack of conservation activities for protecting the existing greeneries. The study also revealed that still there are ample opportunities to enhance the greeneries in Dhaka city by conserving the existing green areas (e.g. parks, gardens, playgrounds etc.), increasing roadside plantation, promoting homestead and rooftop gardening and by initiating afforestation and nursery activities.J.

Highlights
A city with substantial green spaces represents good planning and management, a healthy environment for its dwellers, vegetation and wildlife populations (Adams and Leedy, 1987; Johnston, 1990; Godefroid, 2001)
The development of multifunctional urban green structures can be an important contributor to sustainable urban development in terms of improving the quality of life and environment for current urban populations (Konijnendijk et al, 2004; Wolch et al, 2014).Compare to all other mega cities around the world where concept of urban forestry and urban greening is highly considered as a way of sustainable urban development, in Dhaka city it is a less focused issue and a little initiative is observed in this regard
This study identified that Dhaka is losing its existing greeneries or green spaces enormously still there are ample possibilities to the City Corporation authority, RAJUK (Capital development Authority), urban planners and local inhabitants to enhance the urban greening in the city that can sustain the existing life of the urban population
Summary
A city with substantial green spaces represents good planning and management, a healthy environment for its dwellers, vegetation and wildlife populations (Adams and Leedy, 1987; Johnston, 1990; Godefroid, 2001). Ansari (2008) asserted that the green resources in Dhaka are overwhelmed by a number of limitation inherent to the exceptional mode of urban development, rapid increase of urban population, transformation of green and other open spaces into other types of land use, lack of proper planning and implementation and management restrictions as well. Urban forestry and urban greening is strongly associated with sustainable urban development This is because urban forestry or greening can improve the quality of life and environment of the urban dwellers through its numerous functions such as by reducing urban air pollution load and provide purified air, act as heat absorber during the hot summer in the cities of tropical regions, and increases the aesthetic or recreational value and so forth. The specific objectives of the study were:(i) to provide an overview of urbanization trend and urban greening in Dhaka City (ii) to discuss the importance of urban forestry and urban greening for sustainable urban development and (iii) to explore the prospects and challenges for enhancing the urban forestry and urban greening in Dhaka
