Considering the current trends veered towards urbanization, it has been predicted that by the end of the twentieth century, about 90% of the world’s population would have resorted to urbanized living. Owing to the growing trend in urbanization, vast changes are taking place with relation to the distribution of the human settlements, which has cast a rapid deterioration of the green coverage in the metropolitan areas. Green spaces perform a variety of tasks and play a major part which is important to the urban environment in many ways. ‘Green space’ is a crucial player, when it comes to the contribution it makes by improving the quality of the city environment. Its’ contribution varies in ways such as improving of the quality of air, urban health, reducing urban heat island effect, lessening noise, conservation of biodiversity and bestowing significant socioeconomic advantages. Scholars have confirmed the important, beneficial role that the urban green spaces play with relation to the environment, society and economy. This paper evaluates the level of the function of private green spaces with regard to the environmental, social and economic aspects in a primary residential zone of Galle City in Sri Lanka. Nine variables have thus been recognized in order to create a model for the evaluation of the functions of the private green spaces and the variables that have been proposed are of qualitative and quantitative in nature. Each housing unit (n=280) in the selected residential zone was surveyed in order to collect the data for the multiple regression analysis and develop models to demonstrate the functions of the private green spaces. Results of the research exhibited that only 10 percent of the private green spaces were functioning well in terms of the environment and 13 percent were functioning well socially. It was interesting to note that only a mere 5 percent of the private gardens were functioning economically well in the study area. The social role that the private gardens play is considerably higher than that of the environmental and economic functions. The findings emphasize that the private green spaces possess the ability to offer a variety of functions towards the positive contribution to the urban environment and its population, however it can be surmised that green spaces are not functioning in its’ full potential in the city of Galle in Sri Lanka.
