ABSTRACT
The main purpose of the study was to determine the extent of adoption of roof gardening at Mirpur-10 area under Dhaka city. Attempts were also made to describe some selected characteristics of the building inhabitants of this area. The selected characteristics were: age, family size, family education, family annual income, roof gardening experience, use of information sources, attitude towards roof gardening and knowledge on roof gardening. One hundred respondents were randomly selected from Mirpur-10 area under Dhaka city. Data were collected by using a pretested personal interview schedule during May„2006. Pearson’s Product Moment Correlation “r was used to determine the relationship between the selected characteristics of the respondents with their extent of adoption of roof gardening. The findings revealed that majority (62 percent) of the respondents possessed no adoption compared to 15% and 23% had low and medium adoption of roof gardening respectively.
Out of nine selected characteristics of the respondents, family size ,roof gardening experience, use of information sources , attitude towards roof gardening and knowledge on roof gardening had positive significant relationship with their adoption of roof gardening. Other characteristics namely,: age, family education and family annual income did not show any significant relationship with the respondents adoption of roof gardening. The main problem of roof gardening was selected as lack of time .Most of the respondents were interested to flower plant for their roof garden.
CHAPTER 1
INTRODUCTION
1.1 Background:
Gardening is a great hobby. The garden situated on the roofs of the building
Is called roof garden and the activity is called roof gardening. Dhaka is the capital
of Bangladesh. Near about 10 million people live in this city. Buildings occupy
most of the lands of this city. Many of the buildings are used for residence.
There are a few lands to cultivate vegetables, fruits and flowers or
ornamental plants. But there is a great demand for vegetables, fruits flowers or
ornamental plants in this city. The building inhabitants can grow vegetables, fruits
and flowers or ornamental plants on their building’s roof. But in most cases they
do not grow these plants on their building’s roof. But it is very important to
conserve the Environment of the city as well as produce vegetables, fruits and
flowers or ornamental plants. By gardening the gardener can make his health as
well as his family member’s health better. On the other hand there is a lot of
problems for roof gardening. The citizens have lack of roof gardening knowledge
also. These facts indicate the need for conducting survey on roof gardening. l
1.2 Statement of the problems:
In view of the importance of roof gardening the investigators of this
survey were highly interested to find out the adoption and problems of roof
gardening in Dhaka city entitled 44 Adoption of Roof Gardening at Mirpur-10
area under Dhaka city.”
This study attempted to find out the answer of the following research
questions:
1. What are the respondents selected characteristics ?
2. What is the level of adoption of roof gardening of the respondents ?
3. Are there any relationship between the selected characteristics of the
respondents with their adoption on roof gardening?
1.3 Justification of the study
Many studies have so far been conducted on adoption of various aspects of
agriculture. But only a little research has been reported in home and aboard to
determine the adoption on roof garden of the respondents. However, it
3
is very much important to ascertain adoption on roof garden of the building
inhabitants of Mirpur-10 area under Dhaka city. It is about thirty lakh peoples
were live in Dhaka city. The population of Dhaka city increases day by day .On
the other hand the number of plants of this city were decrease day by day .For the
civilization, our children have to live without green environment that is plants.
We have to live just like machine with plants free environment in this city. So
avoiding this unfair situation, we have to build up garden on our house’s roof
In order to achieve this target it is essential to undertake a program to
motivate for the building inhabitants of Dhaka city. However before making
awareness of the respondents for roof gardening it is necessary to gain clear-cut
idea about the present status of adoption of roof gardening of the respondents. On
the above circumstances the researcher has undertaken the present study entitled
“Adoption of roof garden at Mirpur-10 area under Dhaka city.”
1.4 Specific Objectives:
In view of the problems stated above the following specific objectives were
formulated for giving the proper direction to the study:
i. To determine eight selected characteristics of the building Inhabitants of
Mirpur-10, Dhaka city. The characteristics were as: age, family size,
family education, family annual income, roof gardening
experience, use of information sources, attitude toward roof gardening and
knowledge on roof gardening.
ii. To determine and describe the extent of adoption of roof gardening by the
building inhabitants.
iii. To explore the relationships between the selected characteristics of the
respondents’ with their adoption of roof gardening iv. To identify the problem faced by the respondents.
v. To identify the categories of plants in the roof gardening.
1.5 Limitations
In order to conduct the research in a meaningful and manageable way, it
becomes necessary to impose some limitations in certain aspects of the study. Considering the time, money, labour and other necessary resources
available to the researcher, the following limitations have been observed
throughout the study:
1. The study was confined to small area namely Mirpur-10 under Dhaka city.
2. There were many respondents in the study area, but only the respondents
who were building inhabitants were considered for this study. 3. Characteristics of the respondents were many and varied but only eight
characteristics were selected for investigation in this study.
4. For collection of information, the researcher had to depend on the data
furnished by the respondents during their interview.
5. The present study highlights a new dimension of research in the field of
agricultural extension in Bangladesh and so the researcher could not
provide sufficient evidence in equipping his study report with relevant
literature reviews.
1.6 Assumptions
An assumption is the supposition that an apparent fact or principle is true in the
light of the available evidence (Goode and Malt, 1983). Following assumptions
were in the mind of the researcher during concluding the study:
i. The respondents included in the sample were capable of furnishing
proper responses to the questions in the interview schedule.
ii. Views and opinions furnished by the respondents were Unrepresentative
views and opinions of the study. iii. The responses furnished by the respondents were reliable.
iv. The researcher herself as the interviewer was able to coiled the responses
of the respondents with adequate precision.
v. The researcher who acted as an interviewer was well aware of the social
and cultural environment of the study area. Hence, the data collected by
the researcher were free from bias and the respondents furnished their
opinions without hesitations.

CHAPTER 2
REVIEW OF RELATED LITERATURE
2.1 Review of the previous Research findings
Review was searched in Bangladesh Agricultural Research Council (BARC),
Sher-e-Bangla Agricultural University Library and from Internet searching.
But there was no previous work on the present topics. Only a book reference
was found from BARC Library and two articles were found in Internet
searching. These are described below.
Krupka, B (1992) wrote a book named “Roof gardening: use of plants and
vegetation on buildings.” This book consists of 20 chapters covering the
history and importance of growing plants on buildings from the architectural
and town planning aspects, developments in techniques of roof gardening in
the last decade, the ecological value of growing plants on buildings, habitat
restrictions of vegetation on buildings, planning factors, prevention of
damage to buildings, preparation and protection of the habitat and different
forms of greening. Chapters 10 to 15 cover the choice of plants for intensive
and extensive' greening’ of roofs, walls and noise reduction screens. Chapter
16 to 17 deal with the qualitative requirement of seeds, plants and4ins-tant
vegetation’, and planting and vegetation stands in relation to decline criteria.
Forms of damage, care and maintenance, and performance of roof and fa9 ade
vegetation are covered in the last 3 chapters. The comprehensive coverage of
the theoretical and practical aspects of growing vegetation on buildings, the
clear diagrams and the extensive list of suitable plants make this book a
valuable source of information. It is to be hoped that an English translation
will be made so that the information will be made so that the information will
be more accessible to a wider readership.
Islam (2001) has published an article named “ Roof gardening as a strategy
of urban agriculture for food security' : the case of Dhaka city,
Bangladesh.”.He has reported that urban agriculture in the cities of
developing countries are growing rapidly which also means the number of
low-income consumers is increasing. Because of food insecurity in these
cities is increasing. Urban agriculture (UA) contributes to food security by
increasing the supply of food and by enhancing the quality of perishable
foods reaching urban consumers. The exploration of local socio-economic
and institutional
14
conditions that might promote and hinder urban agriculture is needed to
implement policies that effectively integrate agriculture into the urban
environment. This study aims to identify the potential for and barriers to UA with
reference to rooftop gardening(RTG) and to explore strategies to promote food
security in Dhaka
S. Brenneisen (2001) provided some important information on the topics "Green
roofs-How nature returns to the city” in the International Conference on Urban
Agriculture. He has reported that following a promotional campaign in
1996,green roofs have become an important factor in urban planning in the city
of Basil, Switzerland. An investigation based on an urban ecological assessment
proved the significance of green roofs for modem town-planning strategies. It
showed that the extent of the area with a high environmental load could be
reduced from 19% to2% of the total. Furthermore, bio-ecological surveys
underlined the need for the development of green roof concepts at the scale of the
town. The wide range of vegetation found on green roofs and the variety of
designs available
according

2.2 Conceptual Framework
The conceptual framework of the study of Rosenbarg and Hovland (I960) was kept in
mind while framing the structural arrangement for the dependent and independent
variables. Adoption of roof gardening of the respondents as dependent variable which
is supposed to be influenced and through interacting forces of many characteristics in
his/her surroundings. It is therefore, necessary to limit the characteristics which
include age, family size, family education, family annual income, roof gardening
experience, use of information sources, altitude towards roof gardening and
knowledge on roof gardening. Based on this discussion and the review of literature
the conceptual framework of this study has been formulated as shown in figure 1.

CHAPTER 3
METHODOLOGY
Use of proper methodology is important in a scientific investigation. It requires a very
careful consideration on the part of the researcher to collect valid and reliable data and
to analyze the same properly to arrive to a meaningful conclusion. The methods and
procedures followed in conducting present study are discussed in this chapter.
3.1 Location of the study
There are 28 thanas in Dhaka City. Mirpur-10 is one of thana of Dhaka. It situated on
the northern side of the city of Dhaka. This area was selected as the locales of the
present study. Three thousand families live in this area. Mirpur-section 10 area was
suitable place to research to determine the adoption of roof gardening of the city
inhabitants as it is situated within the Dhaka city. A map of Dhaka district showing
Mirpur, section-10 has been presented in Figure 3.1
3.2 Population and sampling procedure
About 3,000 families lived in buildings in Mirpur, Section-10 area. The family
heads of building inhabitants were the population of the study. A list of total
inhabitants was collected from the ward commissioner’s office. To minimize the
sample size, the inhabitants were randomly selected which consisted of 100
inhabitants. A reserve list of nine inhabitants was also prepared so that the
inhabitants of this list could be used if any selected respondent was not available
during the interview.
3.3 The research instrument
For the purpose of data collection an interview schedule was prepared keeping
the objectives of the research in view. The schedule contained both open and
closed form questions. Most of the questions were simple and direct while some
scales were included in the schedule to collect data regarding the attitude
towards roof gardening, knowledge on roof gardening
21
and adoption on roof gardening. The draft schedule was pre-tested before using it
for collection of data. Based on the pre-test experience, necessary corrections,
additions, alterations and rearrangements were made in the schedule. Thus the
schedule was prepared for final use. The schedule was prepared in the English
version. because all the inhabitants are educated and they were capable of
understanding the questions. The interview schedule has been presented at
Appendix-1.
3.4 Variables and their Measurement
3.4.1 Measurement of independent variables
An independent variable is that factor manipulated by the experimenter in his
attempt to ascertain its relationship to an observed phenomenon (Townsent,
1953).Eight characteristics of inhabitants were selected as independent variables of
this study. Procedures followed in measuring the selected characteristics are
described in the sub sequent sections.
22
3.4.1.1 Age
Age of an individual was defined as the period of time from the birth to the time
of interview and was operationally measured in terms of years. It was located in
the serial no. l of the interview schedule.
3.4.1.2 Family size
The term family size refers to the number of members of the respondents family.
This variable appears in the serial no.2 of the interview schedule.
3.4.1.3 Family Education
Education of a respondent was measured by the highest grade of formal
schooling completed by him or her in any educational institute. If an
individual was found illiterate, he/she was given a score of “0” .A score of 1
was assigned for each class one formally completed or passed.
Family education refers to the total score of education of all the
member of the family. The question for this variable appears in the serial no.
3 of the interview schedule.
3.4.1.4 Family Annual Income
Family annual income of a respondent was measured in terms of thousand taka.
Income from all sources by all the earning family members were added together
to obtain family annual income. A family annual income score was computed by
assigning one (1) point for each thousand Taka. It was located in the item
number 4 of the interview schedule.
3.4.1.5 Roof Gardening Experience
Roof gardening experience of a respondent was measured by counting the
number of years a respondent actively involved in roof gardening. For each Year
of roof gardening experience the respondent was assigned by a score of 1 and so
on. It was located in the item number 8 of the interview schedule.
24
3.4.1.5 Use of Information sources
For measuring use of information sources, the respondents were asked lo choose
one answer among four nature of contact for each media, namely frequently,
occasionally, rarely and not at all. These four options for each media were
defined specially to each media considering the situation, rationality and result
of pre-test. Scores were assigned for all extension media in the following
manner:
The use of information sources of a respondent was determined by adding the
total responses against the 11 selected media. Thus the total score could range
from 0 to 33, where 0 indicating no use of information sources and 33 indicating
very high use of information sources.
Extent of contact Weighting system
Frequently o J
Occasionally 2
Rarely T 1
Not at all 0
25
3.4.1.6 Attitude towards roof gardening
Fifteen statements Expressing possible and negative feelings towards roof
gardening. A statement was considered positive if it indicated a favorable attitude
towards roof gardening. If it indicated a favourable attitude towards roof gardening.
If the case was reserse , it was considered as a negative statement. Out of these 15
statements 8 were positive and 7 negative. Scoring was done by assigning 4,3,2,1
and 0 scores to the five alternative responses as “Strongly agree”, “agree”,
“undecided”, “Not agree”, ’’Strongly disagree” respectively in case of a positive
statement. Reverses were assigned for a negative statement. However, attitude
toward roof gardening score for a respondent was obtained by summing up his
scores for all the 15 statements in item no 11 in the interview schedule. Attitude
score thus obtained for a respondent could range from to 60, where 0(zero)
indicated very unfavourable attitude and 60 indicated highest level of favourable
attitude towards roof gardening.
3.4.1.7 Knowledge on roof gardening
This refer to ones knowledge about roof gardening. It was measured by asking
the inhabitant ten questions on different aspects of roof gardening.
The total marks for all the question was 20. An inhabitant answering a question
correctly obtained the full marks, while for a partial correct answer he/she was
given marks proportionately. Each question contain 2 marks. This score could
range from 0 to 20, o indicating no knowledge and 20 highest knowledge. This
variable appears in the serial no. 12 of the interview schedule.
3.5 Measurement of dependent variable Adoption of roof gardening
A dependent variable is that factor which appears, disappears or varies as the
experimenter introduces, removes, or varies the independent variables
(Townsent,1953)It is often called predictable variable. Adoption of roof
gardening was the main dependent variable of this research. The respondents
were asked to response on (1) the potential area of their house roof for roof
27
garden, and (2) the area covered by roof garden. Adoption of roof gardening of a
respondent was measured by using the following formula:
Area covered by roof garden (s.f) Adoption of roof garden = ---------------------------------- —— x l00
Potential area (total area of the roof (sf)
Thus adoption of roof gardening of a respondent could ranged from 0 - 100,
while 0 indicating no adoption and 100 indicating highest adoption of root' gardening.
3.5 Hypothesis
A null hypothesis states that there is no relationship between the concerned
variables. If a null hypothesis is rejected on the basis of statistical test, it is
concluded that, there is a relationship between the concerned variables. However,
following null hypothesis were formulated for the present study:
1. There was no relationship between the selected characteristics of the family
heads of building inhabitants of Mirpur-10 area under Dhaka and their adoption
of roof gardening.
The selected characteristics were: age, family size, family education, family annual
income, house ownership, roof gardening experience, useful information sources,
attitude towards roof gardening and knowledge on roof gardening.
3.6 Collection of data
Data were collected by the researcher herself during May 2006. To gel valid
pertinent information the researcher made all possible efforts to explain the
purpose of the study to the respondents. Interviews were conducted with the
respondents in their homes. While starting interview with respondent, the
researcher took all possible care to establish rapport with him/her so that he/she did
not feel hesitant or hesitate to furnish proper response to the questions and
statements in the schedule. The questions were clearly explained wherever any
respondent felt difficulty in understanding properly. As all of the inhabitants were
lived in city, they are educated that ensure the researcher to collect information
from them easily.
29
3.7 Compilation of data
After completion of field survey data from all the interview schedules were
compiled, tabulated and analyzed according to the objectives of the study. In this
process, all the responses in the interview schedule were given numerical coded
values. Local units were converted into standard units. The responses to the
questions in the interview schedules were transferred to a
master sheet to facilitate tabulation. Tabulations and cross tabulations were done
on the basis of categories developed by the investigator herself.
3.8 Data processing and analysis
The analysis was performed using SPSS (Statistical Package for Social Science)
Computer package. Descriptive analysis such as range, frequency count, number
and percentage, mean and standard deviation were used wherever possible.
Pearson’s Product Moment Coefficient of Correlation (r) was used in order to
explore the relationship between the concerned variables. Throughout the study,
five percent 0.05 level of probability with an accompanying 95 percent
confidence level was used as a basis of rejecting a null hypothesis.

gardening was measured by testing the following null hypothesis: “There is no
relationship between age of the respondents and their adoption of roof
gardening.” The computed value of ‘r* (0.066) was smaller than that of the
tabulated value (0.196) with 98 degrees of freedom at 0.05 level of probability.
Hence, the concerned null hypothesis was accepted. It could be concluded from
the finding that there was no significant relationship between age of respondents
and their adoption of roof gardening.
4.3.2 Family size and adoption of roof gardening
The relationship between family size of the respondents and their adoption of
roof gardening was measured by testing the following null hypothesis: “There is
no relationship between family size of the respondents and their adoption of roof
gardening.” The computed value of V (0.240) was greater than that of the
tabulated value (0.196) with 98 degrees of freedom at 0.05 level of probability.
Hence the concerned null hypothesis was rejected. The finding indicated that the
family size of the respondents had a positive
43
significant relationship with their adoption of roof gardening. This implied
that the more large family size of a respondent, the more was the adoption of
selected roof gardening.
4.3.3 Family education and adoption of roof gardening
The relationship between family education of the respondents and adoption of
roof gardening was measured by testing the following null hypothesis: “There
is no relationship between family education of the respondents and their
adoption of roof gardening.” The computed value of V was (0.171) was
smaller than that of the tabulated value (0.196) with 98 degrees of
freedom at 0.05 level of probability. Hence, the concerned null hypothesis was
accepted. It could be concluded from the finding that there was no significant
relationship between family education of the respondents and their adoption of
roof gardening.
4.3.4 Family annual income and adoption of roof gardening
The relationship between family annual income of the respondents and their
adoption of roof gardening was measured by testing the following null
44
hypothesis: "There is no relationship between family annual income of the
respondents and their adoption of roof gardening." The computed value of Y
(0.062) was smaller than that of the tabulated value (0.196) with 98 degrees of
freedom at 0.05 level of probability. Hence, the concerned null hypothesis was
accepted. It could be concluded from the finding that there was no significant
relationship between family annual income of the respondents and their
adoption of roof gardening.
4.3.5 Roof gardening experience and adoption of roof gardening
The relationship between roof gardening experience of the respondents
and their adoption of roof gardening was measured by testing the following null
hypothesis: “There is no relationship between roof gardening experience of the
respondents and their adoption of roof gardening.” The computed value of V
(0.764) was greater than that of the tabulated value of V (0.254) with 98 degrees
of freedom at 0.01 level of probability. Hence, the concerned null hypothesis was
rejected.
The findings implied that roof gardening experience of the respondents had a
positive significant relationship with their adoption of roof gardening. It
could, therefore, be concluded that the more roof gardening experience of a
respondent, the more was the adoption of roof gardening.

The relationship between attitude towards roof gardening of the respondents
and their adoption of roof gardening was examined by testing the following
null hypothesis: “’There is no relationship between attitude towards roof
gardening of the respondents and their adoption of roof gardening." The
computed value of V (0.827) was greater than the tabulated value of V (0.254)
with 98 degrees of freedom at 0.01 levels of probability. This means that the
concerned null hypothesis was rejected. Thus the attitude towards roof
gardening of the respondents had a positive significance relationship with
their adoption of roof gardening. The finding is logical, because the more
attitudes toward roof gardening, the more was the adoption of roof gardening
of the respondents.
4.3.8 Knowledge on roof gardening and adoption of roof gardening
The relationship between knowledge on roof gardening and their adoption of
roof gardening was examined by testing the following null hypothesis: “There
is no relationship between knowledge on roof gardening and their adoption of
roof gardening.” The computed value of V (0.341) was greater
•17
than the tabulated value of ‘r ‘(0.254) with 98 degrees of freedom at 0.01 levels
of probability. This means that the concerned null hypothesis was rejected. Thus
the knowledge on roof gardening of the respondents had a positive significance
relation with their adoption of roof gardening.
4.4 Problems Faced by the respondents
Ten problems which might be laced by the respondent were identified. In respect
of each problem, each respondent indicated to what extent that problem was
faced by him. His response was noted by putting a tick mark in any of the five
columns and was quantified by: very much (•!), much (3), some (2), little (1), not
at all. (0).
The roof gardening problem index (RGPI) of a particular practice was measured
by using following formula.
RGPI = 4xf1 + 3xf3 -I- 2xf2 + 1 xf! + oxf0
Where, RGPI =
f4= number of respondents who faced very much problems
f3 = number or respondents who faced much problems
f 2= number of respondents who faced some problems
f1 = number of respondents who faced little problems
f° = number of respondents who faced not at all
problem
While 0 indicating not at all problem and 400 indicating very much problem
By this formula, the most important problem of the respondents’ was
identified as “lack of time”. Other problems were followed by “roof gardening
is laborious, lack of knowledge, difficult to manage necessary elements,
difficult to make roof garden for a tenant, seedling damaged, theft seedling,
flowers, fruits etc by thief no benefit in roof gardening, lack of irrigation
facilities and lack of sun shine due to side building respectively.
4.5 Categories of plants in the roof garden:
