A Acknowledgement Curriculum Vitae Abstract Hanoi is a rapidly developing city - in terms of area, population and economy. It also has to face social and environmental problems that often accompany the fast development of a city. Increasing environmental pollution leads to a decrease in living conditions, such as clean water, housing, social services, etc., for most of the city’s inhabitants. Other well- known social problems in cities worldwide also occur in Hanoi nowadays, for example inequality, food supply, and unemployment. In addition, the society is altering; lifestyle- change is a permanent process. Today, it seems that the changing process in Asian countries is rather leap-frogging than continuously. Although many research projects concerning to urban green areas in Hanoi have been completed recently, less is known about utilization of parks&gardens in a practical and systematic way. This study aims at contributing to fulfills the gaps with up-to-date fact and figure of parks’ utilization in the inner city of Hanoi. Based on “grounded theory”, triangular methodology was applied to collect empirical data in four main parks in the inner city of Hanoi namely: Thong Nhat, Bach Thao, Hoan Kiem, and Lenin. Scientific observations, visitor countings were done in 2010-2011; including 2143 face-to-face interviews to park users covering the course of the year and a small online-poll of 113 responses. Thirthteen interviews with experts have been done in several phases and taken into account for discussing and testing hypotheses. Empirical results have shown that utilization of the parks is in abundance in terms of the use- numbers as well as activities. A comparision between the courses of the day for parks in Berlin and
