4. Results
4.1. Comparison of Preferences for Different Features across All Four Parks
In this section different categories of factors are compared to see if there are any significant differences in preference rankings across each of the gardens/parks and whether modern or traditional ones appear to be favoured in general. These results relate to the first part of the research question. In interpreting the Likert scale we took a mean score of over 3.5 to represent the higher ranges and below 2.5 to represent the lower ranges with a range of between 2.5 and 3.5 to mean a moderate preference.
Key Design Elements
The results of chi square test for the key design elements (
Table 4) revealed that there was a significant difference across the four parks: overall, in descending order of degree of difference are: the presence of flowing water; signs and information; shade; places to sit and relax; light coloured street furniture; ornamental fountains; lighting; beautiful landscape design and trees and flowers. The means of the Likert scale preference scores (1–5 scale for each) are presented together with the standard deviations (
Table 5).
Taking each factor at a time, looking at the means from
Table 5, we can see that fountains score on average much higher in Chehelsotoon and Bagh-e-Phin than for Mellat or Jamshidieh (where they are below average): the traditional parks, with water features as key defining elements are preferred here (although the standard deviations show a fairly wide range). For the presence of trees and flowers there is not much difference overall—these are important feature in any park, as would be expected. A beautiful landscape design—a somewhat difficult and subjective factor to interpret perhaps—is just above average for all parks, with a relatively low standard deviation. Signs and information are rated much more highly for the two traditional parks than the two modern ones—possibly because visitors wish to understand the historical features of these parks, which are interpreted using signs on-site. The aspect of light coloured street furniture is rated fairly low for all parks and with a similar standard deviation—clearly not an important design factor despite being listed by experts in the Delphi study. The presence of lighting is rated higher for the traditional parks than for the modern ones—despite the fact that they close at 6 pm while the modern ones stay open until the late evening. However, the traditional parks have special lighting effects to pick out the architecture for example, which may account for this. The importance of providing shade is clear—the means are all over 4, closer to 5 in some cases and with lower standard deviations than for several other factors. The presence of ornamental fountains stands out as the most important factor for the modern parks, though equal to others for the traditional parks, where ornamental fountains are as if not more important. Flowing water is also seen as more important in the traditional parks—although closely followed by Jamshidieh. Thus water as a key element seems to stand out as a more defining feature in the traditional parks, even though the modern parks each include large water features. Finally, places to sit and relax score above the middle range of the rating scale, with not much to choose among the parks.
Accessibility
This section looks at the relative importance given by the respondents to accessibility to the parks and gardens by various means.
Table 6 presents the Pearson chi square test for the five items. The results revealed that there was a significant difference across the four parks. The greatest differences were, in descending order, park usability in the daytime and at night; access to the park on foot; access to the park by bicycle; access to the park by car; and access to the park by public transport. The means of the Likert scale preference scores (1–5 scale for each) are presented together with the standard deviations (
Table 7). Thus, scores above 3 are in the higher range of average preference and scores below 3 in the lower range.
From the means and standard deviations in
Table 7 we can see that for the factor of access to the park by bicycle, the means hover around the mid-range of 3 in the 1–5 Likert scale of preference, with high standard deviations, suggesting that there is not much agreement here. This is perhaps not surprising given that cycling is not yet a major form of transport in Iran and that two of the parks (Jamshidieh and Bagh-e-Phin) are located well away from where a lot of visitors live. Jamshidieh is not suitable for cycling because it is located in hilly, rocky topography and Bagh-e-Phin is located in a religious city, where people live in a more traditional manner. The rating for the importance of access by car to the parks is generally similar and just above the mid-range of the scale but with a similar standard deviation as for access by bicycle. The importance of accessibility of foot scores is somewhat higher than that for car or bicycle, especially so for Chehelsotoon—which also happens to be the one park located in the centre of the city where foot access is much easier than for the rest. The aspect of usability at both daytime and night reveals rather odd results—this is rated higher for the two traditional parks which are closed to visitors at 6 pm while the modern parks are used until well into the late evening. Accessibility by public transport is rated as above the mid-range of scores although with a larger standard deviation than for some other factors. This could be because public transport connections are not well-developed and are unreliable to these specific parks.
Cultural Facilities, Activities and Services
This section looks at the range of different cultural facilities, activities and services which are frequently available in Iranian parks.
Table 8 presents the results of the Pearson chi-square test for these seven aspects. These are ranked in the descending order of: access to media, availability of libraries and study facilities, the opportunity to paint or pursue art activities and the availability of souvenir or handicraft shops or stalls.
From the means and standard deviations presented in
Table 9 we can see that access to media is seen as somewhat important by respondents in Mellat and Chehelsotoon but less so in the others (although with wide standard deviations). The availability of libraries and study facilities is not seen as being important to visitors to the modern parks and only of moderate interest to those visiting the historic parks—perhaps if those facilities offer information on the history of those places. Nowhere is there any real importance given to the opportunity to pursue artistic activities while souvenir or craft shops or stalls—despite them being common sights—are also not considered to be important except to a slight degree in Mellat park where there are the most of such kiosks.
Safety and Security
This section covers the category of factors related to the safety and security, especially against crime, of the four sampled parks. The results of chi-square test (
Table 10) revealed that there was a significant difference across all four parks in the descending order of physical safety of spaces, facilities and equipment, having a police presence at the park and there being an overall feeling of security and calmness.
The means and standard deviations for the factors related to safety and security in
Table 11 show some differences. Aspects of physical safety are perceived as being important in all parks, slightly more so in Mellat and Chehelsotoon. Having a police presence is seen as less important than an overall feeling of safety and calmness which applies to all parks but stands out more so—with a smaller standard deviation—for Chehelsotoon.
Spiritual Factors
This section looks at a category of perceptual factors broadly defined as covering spiritual aspects. The results of the chi square test (
Table 12) revealed that there was a significant difference across the four parks in the descending order of obtaining inspiration hearing broadcast music, being able to feel less stressful, feeling revitalised, being able to leave cares behind and being away from crowds.
The means and standard deviations presented in
Table 13 show that obtaining inspiration is somewhat important—Chehelsotoon stands out from the others in this regard, and to some extent also in Mellat. Hearing broadcast music is also somewhat popular, also more so in Mellat (where the park is full of activities and people having fun) and Chehelsotoon. However, these two aspects are overshadowed by the importance placed on the four aspects associated with feelings, with revitalisation standing out from these for all parks except Bagh-e-Phin. This shows that many of the benefits associated with using parks to offset the stresses of modern life are also seen as important in Iran.
Recreational Opportunities and Facilities
This section looks at the relative importance of a category of factors grouped around opportunities for recreation activities and associated facilities. The results of the chi-square test (
Table 14) revealed that there was a significant difference across the four parks in the following descending order: opportunities to buy food; having places for children to play and have fun; facilities for exercise; opportunities for group and social activities; opportunities to play informal games; having the park useable by older people; opportunities to cycle; opportunities for walking; opportunities to eat; opportunities to spend time with the family; opportunities for spending time with friends; presence of playing fields.
The means and standard deviations presented in
Table 15 show that there are some wider differences among these factors than for many of the other categories. For all the activities associated with recreation and play, the traditional parks score much lower—it is clear that these are not seen as appropriate in such parks or else there is no specific provision for them. The same applies when scoring for the importance of buying food or being able to eat. For all the more social types of activities the differences are much less between all the parks and factors such as spending time with family or friends are rated the highest on average. One aspect which stands out is the much lower score given to the usability by older people at Jamshidieh, which has many steep paths in its hilly terrain.
4.2. Testing for the Components Which Predict Successful Parks
The results of the factor analysis are presented in
Table 16 and show that from the 42 existing items, 11 major components can be identified.
From
Table 16 we can interpret it as follows—each descending component number explains a proportion of the variance within the data and combines variables with a degree of interdependency into single (unobserved—i.e., not directly visible in the data as a whole) latent variables. The predictive value of the identified latent variable decreases as we move down the table, since it explains less of the variance (although they are still relevant latent variables). These are described and named (for better understanding and future reference) below. In doing this we looked at the combination of the variables contributing to the factor and we thus tried to find a simple yet evocative term to describe each.
The first set of factors with the most components is ‘having fun and enjoying oneself’– with children, with music, eating, playing games and taking exercise. This is the latent variable which can be recognised as being typical for visiting an urban park. The second set comprises aspects associated with there being ‘no barriers to using the park’—barriers preventing getting there, feeling secure and finding one’s way about—important aspects often highlighted in the literature. The third set is associated with ‘leaving one’s cares behind’—being able to stroll, feel revitalised and that one’s possessions are safe—an important aspect in enabling visitors to enjoy a visit without feeling anxious. The fourth set can be termed ‘relaxing in the presence of natural beauty’—water, nature, trees and flowers, lighting and a beautiful design—all features that are also important in providing a contrast with urban life and which are key aspects featured in the literature. Fifth, with fewer components, is ‘strolling and browsing’—away from other people, looking at craft souvenirs—a minor activity. Next, the sixth set is ‘being with my family in nature’. The seventh set can be termed ‘being social and creative’—using the park furniture to be in a group and maybe eating or doing art or other creative activities. The eighth set is a single factor of ‘being inspired’ while the ninth is ‘sitting in the shade with friends’. The tenth is a single factor of ‘using the library’ while the final set of two can be termed a ‘safe place to go for a trip’—combining car access with police presence. These last six factors are less important or of interest to a smaller number of visitors.
4.3. Testing for the Differences between the Two Types of Parks
In order to test for differences between the park types,
Figure 3 shows the NMDS ordination plot generated by the process described in the methods section.
For reading the plot it is necessary to remember that each point represents an individual respondent and behind these points are all the answers given in the questionnaire survey. The yellow circles (added by the authors for clarity) represent regions where there is a stronger tendency for each of the named demographic variables to be associated with the visitors to each park.
What we can thus interpret from the results of the NMDS analysis is as follows. For the demographic variables we can see a stronger association between gender and a preference for the modern parks, especially Jamshidieh, since there is a region at this point highlighted with a yellow border. For occupational status, there is also a tendency for preference for the modern parks, this time focused on Mellat as well as, to some extent, Jamshidieh, also enclosed by a yellow border. For marital status as well as age, there is also a further region on the plot related to the two modern parks, Mellat and Jamshidieh. Only when we look at educational level do we see a stronger preference associated with a region on the plot with the traditional parks of Bagh-e-Phin and Chehelsotoon. Turning to the three significant sets of factors: recreation, accessibility and cultural activities, in the plot there are three directional arrows, one for each, which show the tendency for the strength of association between them and the parks. In the case of accessibility, it is not a very strong trend but it is more for the modern parks than the traditional ones, while for the factors of recreational value and cultural activity the trends are strong and in the same general direction—clearly focused on the modern parks.
5. Discussion
We can see from the results that of the many factors we identified from the literature and in our small Delphi survey—factors that tend to be universal—most of these scored at a level of ‘agree’ or ‘strongly agree’ (scores 4 or 5 on the Likert scale) in all parks surveyed. In this regard the needs of the contemporary urban population of Iran are not very different from anywhere else. When considering who uses the parks, from the analysis of the characteristics of the respondents in
Table 2, we can see that there was a large majority of young single men in all parks and fewer women or married people. We are confident that the sampling procedure used and the large sample size correctly picked up the balance of users over the period of data collection. Thus, this being the case, there are several aspects that can be taken into account—first, to see why there is this imbalance—which might be associated with cultural and other aspects. The problem of lower uses of parks by women in Iran has already been noted and other studies have identified the need to pay more attention to their needs and to provide suitable supporting structures [
38]. This information can help decision-makers to plan according to people’s needs and expectations. As noted in other studies, it is also necessary to know for whom a park is targeted, requiring data about, for example, the age, gender, ethnicity and socio-economic status of the users, as well as something of the demand for the various activities programmed there [
9]. Rezazadeh [
54] considers that it is necessary for politicians and park programmers to involve women’s interests with increasing gender awareness in order to resolve this imbalance in the pattern of park users. Our survey goes some way to identifying the characteristics of users to two different types of parks—the modern and traditional, where there are both similarities and differences in the profiles.
We can compare the results of the park-specific items with the factor analysis. The loading under the first important factors is of a range of attributes we have termed under the heading of ‘
having fun and enjoying oneself’ and the variables included in this factor were also generally evaluated at a mean above 3.5 in the scale of importance as rated by the respondents for all parks but especially for Mellat and Jamshidieh, the contemporary parks. This highlights the importance of considering this kind of recreation in the social life of the Iranian people. These results support those previously reported [
23,
24], which stress the role of green spaces in increasing inhabitants’ well-being and physical health. For this reason, urban parks should be used to promote the well-being of the Iranian urban society and increase the liveability of cities [
46].
The second factor which we have named ‘no barriers to using the park’ is also very important—one of the issues commonly identified in the literature concerns inequity of access, barriers of various sorts—physical or social, for example. These factors were also generally highly rated by respondents—apart from accessibility by bicycle—which is an aspect of transport which needs greater development in Iran compared to many other countries.
The third factor
‘leaving one’s cares behind’ focuses on mental well-being. In countries such as Iran, in which urban dwellers (in common with many other countries but with specific aspects here) face many mental and physical pressures, people ought to be using parks and green spaces more than they do. There is some evidence that Iranians attach a special value for nature [
55] and would like to spend their leisure time outside of their residences in parks, in order to feel happy. However, earlier studies by the authors have shown that park availability is not equally distributed [
9,
56]. The aspects included in this analysis were also ones rated highly—especially that of feeling revitalised, which was one of the highest scored aspects overall.
Relaxing in the presence of natural beauty is the next factor and the last one to be composed of a number of aspects. The fact that this comes as the fourth major factor is interesting—it seems to show that while important, it is something of a bonus in addition to the earlier and more significant factors. This was also reflected in the scores where aspects such as trees and flowers, lighting or beautiful design were not as highly rated compared with some others, and where there were some differences between the two types of park.
The rest of the factors are based on fewer aspects and explain much less of the overall variance within the data and they reveal some lesser characteristics associated with the parks and their visitors—ones which are perhaps important to some people but not generally.
According to these results, a majority of park users focus on those aspects we have named ‘
having fun and enjoying oneself’—’
being with friends’, ‘
spending time with family’ and ‘
walking’ being among the most important aspects contributing to this. This emphasises the importance of the social life for the Iranian people, as Dastmalchian et al. and Fakuhi noted [
57,
58], reflecting the strong family orientated living structures. In addition, while some younger people spend less time with their family and may spend their leisure time individually, couples and couples with children spend more of their leisure time together. This is consistent with Bedimo-Rung et al. [
20], emphasising the role of urban parks as places for people to socialise with their families and friends.
Regarding the aspect of physical exercise which is also contained within the factors for ‘
having fun and enjoying oneself’, as Mozaffari et al. [
59] noted, sport and exercise only forms a moderate component of use of public spaces in Iran. This latter finding reflects Ghandehari et al. [
22], who found that a majority of Iranian park users preferred less intensive physical activity (recreational walking) and proposed that more needs to be done to encourage higher intensities of exercise in parks.
The ‘
having fun and enjoying oneself’ factor has the highest inter-correlation and accounts for the most variance. The second factor, of ‘
no barriers to using the park’ also includes the general feeling of safety which is important as Iranian people like to use parks at night when it is cooler in summer—especially younger people [
9,
38,
56]. As Salehifard et al. note [
8], for improving the quality of urban parks to increase public satisfaction, park facilities can be an effective guide.
The results of the NMDS analysis showed quite clear differences for the main groups of elements extracted from the questionnaire (correlated via the factor analysis using the ‘envfit’ function with high enough statistical significance, and then fed into the NMDS)—referred to as accessibility, cultural activity and recreation. We can see that there is a tendency for being a higher preference among different demographic groups for the modern parks. This accords with the results of the factor analysis—where the first three or so factors align well with the NMDS factors and are also associated with aspects that do not fit with what can be done in the traditional parks due in part to their historical character and design. This is interesting, because when they were first built they provided the elites at the time opportunities for ‘having fun and enjoying oneself’ but the forms of enjoyment were very different to nowadays. The overall status of ‘cultural elements’ in the sample parks was rated fairly low amongst the scores by the respondents in our survey.
It should be noted that the two historical parks are also museums and charge an entrance fee as well as closing earlier than the modern parks. This did not seem to affect the general preferences for the factors tested in the questionnaires. However, the tendency shown in the NMDS plot was for their visitors to be better educated. We might infer that this reflects the museum status. Thus we should be somewhat circumspect in terms of what we can conclude from this as the fact that there is an entrance fee may have affected the results, presenting barriers to access by some people. Within the data on preferences for specific factors there was some difference between the park types but it was not very pronounced apart from the presence of ornamental fountains, flowing water and information signs (relevant because they are museums). While there is a preference overall for the contemporary parks we cannot infer anything more specific about the contribution of Persian traditional style here, apart, perhaps, for the emphasis on water which was highlighted by Beshbahani and Naima [
42,
44] (bearing in mind that such gardens served rather different functions from today’s parks).
The question remains—if the traditional parks as a whole do not answer the contemporary needs of Iranians then are there some specific elements that might be used, with reinterpretation in newer parks? As Shahcheraghi, [
45] notes, one of the most important reasons why Persian (Iranian) gardens have remained attractive over the centuries is the focus on activating all the senses (sight, hearing, smell, touch and taste) where the role of water—in part to provide a sound to counteract external noise—was also important. Thus, we can propose that when modern designers work on a new park or reconstruction of an existing one, they might consider giving attention on harnessing this sensory concentration while reacting to the kinds of preferences we have uncovered in this research. Filling the parks with cultural centres and activities is not so important—those who were educated and preferred this visited the traditional parks.
Therefore, sufficient knowledge about the user groups and their cultural situation and needs in interaction with the environment can result, in accordance with the research of Sharefi [
37] in improving the functions and the environmental balance, stability and sustainability and makes a lively space with sufficient social security. All of these statements indicate the importance of public parks, therefore urban planners should consider all these elements in the planning and designing of parks in metropolitan area. For a deeper understanding of how to reinterpret the best that Persian or Iranian traditions have to offer, we should study their historical roots [
13].
Limitations and Further Research
The research was based on a study of four parks—two in Tehran which were built immediately before the Islamic revolution in the time of the last Shah, when westernising tendencies were dominant, and two much older historical Persian gardens. To that extent, the parks are not representative of all parks in Tehran or Iran. While we tried to test the differences between contemporary and traditional parks, the fact that the latter are also museums and charge an entrance fee could have affected the results to some extent. If it is considered interesting for possible further research, then a more focused look at the differences could be undertaken. For example, by designing the survey to ask questions about preferences for factors related to parks in general and then, separately about the specific park being visited, it may be easier to extract results to determine the differences as well as similarities more clearly than we were able to do. However, the work is intended to complement other work carried out by the authors which looked at a wider sample—including the two Tehran parks considered here [
9]. Nevertheless, if the conclusions we have drawn are to be more generalised, similar research would be invaluable if carried out using similar methods on more parks in more cities. One shortcoming is that those who do not visit the parks were excluded from the survey—which would have had to follow a different design. The research was undertaken some years before the current Covid-19 pandemic and it could be expected that perceptions of the value of parks could have changed as a result of people being unable to visit them so easily.
As the possibilities of a single survey are limited, we suggest that further research could explore additional factors, including more design-related aspects such as layout, proportion of open to enclosed spaces and formality or informality of style.
6. Conclusions
The research reported in this paper asked the following research question:
The study revealed a number of factors that emerged from the collection of aspects rated as more-or-less important by the respondents of which three key factors emerged which we named as ‘
having fun and enjoying oneself’, there being ‘
no barriers to using the park’ and
‘leaving one’s cares behind’, followed by a fourth, less significant one,
‘relaxing in the presence of natural beauty’. The aspects comprising these factors are thus those that should be the focus of park designers in future, while the other factors, while not being ignored, can be given less prominence. We suggest therefore, that planners take the evidence we have presented here and use it to evaluate any particular park in terms of what it offers—or should offer—in this respect. This is important given the problems of quality of many parks in Tehran as revealed in previous research [
9]
In relation to the second part of the research question, we can conclude that on the whole the modern parks were found to be generally preferred over the traditional ones—with some provisos in relation to the presence of ornamental fountains and flowing water. These differences were not huge, perhaps being affected by the survey design and selection of parks to study. We also suggest that these key features of traditional parks could be further incorporated into contemporary ones in order to strengthen their cultural connectedness and to rediscover the sensory concentration system once used to such powerful effect but which would also help in the provision of benefits to modern users.
According to this study, the results we have presented reinforce the importance of considering recreation in the social life Iranian people and for promoting a healthier lifestyle. Most of the respondents we surveyed feel happy and satisfied when they are in parks with their friends and families undertaking a wide range of informal ‘fun’ activities. This revealed that in Iran, where family relationships are still strong, urban parks are important places for people to socialise with their families and friends. So parks directly or indirectly, support the quality of life.
Considering the spiritual factors that we examined, most people said that they go to parks to relax, reduce stress and to leave their cares behind. In Covid-19 times this aspect could be even more important for ensuring better mental well-being among urban citizens.
