Green infrastructure refers to the network of natural and semi-natural areas, features and spaces in rural and urban areas, terrestrial, freshwater, coastal and marine areas. Green infrastructure can be strengthened through strategic and coordinated initiatives that focus on monitoring, restoring, improving and connecting existing areas and features as well as creating new uses and features. The principal issue that stimulates this work is to observe how planning policies could contribute towards achievement of sustainable urban development in Malaysian urban centres using GI attributes. The procedure involved for conducting this work was qualitative content analysis of planning policies that guides physical development of Peninsular Malaysia. The analysis conducted revealed the comprehensiveness of the GI. The policies give more emphasis on protection of natural areas, followed by conservation of Malaysian environment and provision of urban green spaces. The provision of urban trail was not provided anywhere in the policies analysed.

Open spaces have a significant positive impact on the overall well-being of the residents of urban areas and the influence on the use of recreational facilities due to the extent of the residents' engagement with these infrastructures and active lifestyles. The effectiveness of using these spaces on the well-being of residents is on their relative quality, quantity, and accessibility. Putrajaya houses 350,000 residents; about 4,931 (37%) of the total landmass was designated as open space to have a balanced city. Four of the twenty open spaces were purposeful selected based on their respective quality and services for the harmonious development of Putrajaya. A convenient sampling technique (non-probability) determines the respondents in each designated open space. This research used the survey data collection method to collect the primary data, using a cross-sectional approach. Pearson product-moment correlation analysis was used to determine the extent and direction of the relationship between open space attributes and health promotion. And multiple regression analysis (entered method) was adopted to predict the health promotion' of residents who visited the provided open spaces based on their respective quality, quantity, and accessibility. The results reveal that the areas' sizes, existing facilities, and greenness are the predominant influencing incentives that attract patronage by both local and international users. Meanwhile, when designing open space to promote the health status of respective users, effort must be toward providing high aesthetic quality in sufficient quantity and size, as indicated in this study.

Systematic distribution and management strategy of urban green spaces has proved to have positive impact (positively influenced) on aesthetic features of urban environment. This translated into greater neighbourhood and visitors' improved overall satisfaction. However, on the contrary, this manifests to affect the natural features of the urban environment, leading to non-negligible dissatisfaction. Careful consideration of green space is judged based on their particular necessity in terms of quality and service provision towards the desirable development of Putrajaya. In this study, 386 samples are considered based on Krejcie and Morgan 1970 sample size formula. The results obtained indicated a strong positive relationship between urban green space attributes and satisfaction. Whereas, results of regression analysis shows that the entire predicting variables have significant unique contribution in determining satisfaction to urban green spaces visitors' in Putrajaya.
