6 Outlook and Recommendations
Based on all the applied information sources in this chapter, an outlook for the future
development of UGAs in inner Hanoi will be rendered. This prognosis refers to the
hypotheses from the beginning. Afterwards, eight clear recommendations will be given
derived from the experiences and results of this study.
Firstly, it is necessary to give a short critical review regarding the information basis.
6.1 Limitation
The data basis of this thesis has been very broad: from the study of secondary information
sources to primary empirical surveys. Nevertheless, there are some constraints, which
should be kept in mind.
The main purpose has been to give a broad overview of most influencing factors
concerning UGAs. The empirical information collection served mainly as a kind of
stocktaking for a serious data basis further on. Not all surveys are statistically validated;
they only give a first indication of the current situation. These surveys have to be improved
by future surveys.
For example:
Face-to-face interviews with parks user were statistically significant based on a high
number of respondents, but unfortunately missed the peak days of natural comfort
which are defined by NGUYEN/REITER (2011:327);
Visitor countings can only give a first orientation/impression about the real number
of visitors per day– due to huge personal efforts of countings;
Online surveys have been a first attempt to use a new survey method, however the
necessary motivation for participation (e.g. some benefits or awards) could not be
given in the frame of this thesis.
The focus of surveys lies on the current visitor structure. Further studies need to involve
people who are not potential park users to gather information on why they do not like to
visit a park.
Despite these weaknesses, the information basis of this thesis delivers a broad and solid
base for further studies, and gives a good orientation for urban planning.
6.2 Prognosis (outlook)
As described in chapter 5, a sharply increasing demand for more UGAs in Hanoi will be
unavoidable. Thus hypothesis-1 (see chapter 1.4) can be validated:
