Unformatted text preview: in a field of research called urban morphology
(Rådberg & Friberg, 1996). This field is in the borderland between several disciplines,
chiefly city planning, history of architecture and art history (ibid), but I would also include
landscape architecture here.
We may say, thus, that the second study is an epidemiological and urban morphological
investigation of urban green spaces as a health-promoting element of city planning. I wish to
emphasize the generally applicable aspect of Study 2 – that the topic concerns everyone who
lives in a city and who in any way works with city planning. The goal of the study is that the
results should be useful in practice in community debates, practical planning of large land
areas and in planning processes in which more detailed sketches are prepared.
Thus, the perspective of Study 2 is to investigate whether verdant urban environments help
to maintain and fortify health and to consider how such environments should be planned.
Study 2 is presented in Papers III, IV and V. Methods in the dissertation
The area of investigation undertaken in the present dissertation is complicated, which is why
the studies have been designed according to the principle of triangulation. There are five
basic types of triangulation (Janesick, 1994): data, investigator, theory, methodological and
interdisciplinary. Three of them are used here:
Data triangulation - the use of a variety of data sources to study a single problem
Methodological triangulation - the use of multiple methods to study a single problem
Interdisciplinary triangulation - incorporates the use of other disciplines
The use of several different methods is in line with the dissertation’s applied approach,
because it is a natural part of a practicing landscape architect’s work to view and elucidate
problems and situations from several different angles and perspectives. Given the present
applied research perspective, it is important to try to understand why and how people are
affected by the physical environment and its design. Finding the answers requires different
data acquired through different methods, such as study visits, discussions, literature reviews,
postal surveys and statistical calculations. The dissertation’s field of study – landscape
architecture and health – is broad and borders on several other research disciplines focused
on human beings, their health and their living environments, chiefly landscape architecture,
architecture, general planning, environmental psychology as well as medicine,
physiotherapy, occupational therapy and horticultural therapy. 19 The number of landscape architects in Sweden who are conducting research is slowly
beginning to increase, though researchers in the present field of study are still
underrepresented. I wish to emphasize, however, the general and applicable aspects of the
dissertation. My hope is that it may be used in societal debates and as an inspiration during
design and planning at the overall and detail lev...
