Access and use of agricultural information and knowledge in Tanzania

Abstract

Purpose
The purpose of this study is to assess access to and use of agricultural knowledge and information in the rural areas of Tanzania.

Design/methodology/approach
Mixed quantitative, qualitative and participatory methods were deployed. Semi‐structured interviews were used to collect qualitative and quantitative data from 181 farmers in six districts of Tanzania. Focus groups and participatory techniques (i.e. information mapping and linkage diagrams) were also used to collect qualitative data from 128 farmers in the same districts.

Findings
The results showed that deep, rich and complete data can be collected through the mixed quantitative, qualitative and participatory techniques. The findings demonstrated that the knowledge and information needs, and information‐seeking patterns of farmers were location specific. The major sources of information for farmers were predominantly local (neighbours, friends and family), followed by public extension services. Apart from radio and cell phones, advanced technologies (i.e. internet and e‐mail) and printed materials were used at a low rate despite their existence in the communities.

Research limitations/implications
The study necessitates a need to conduct regular studies on information needs, map communities' knowledge and information sources, create awareness of information sources and knowledge culture, use participatory methods in design and development of technologies and use multiple sources of knowledge and information (such as print and technologies) to deliver relevant information to farmers.

Originality/value
The study provides a deep understanding of access to and use of agricultural knowledge and information in the rural areas, which necessitates a need for demand‐led and client‐based knowledge and information services in order to meet the disparate farmers' needs. These findings can serve as an example for the increasing use of mixed quantitative, qualitative and participatory methods in information behavior research.

Abstract
This paper assesses the flow of agricultural knowledge and information in the rural areas of developing
countries, with a specific focus on Tanzania. Focus groups and information mapping and linkage diagrams were
used to triangulate with the interviews’ data in order to bring together the strength of all data sets to validate,
confirm and corroborate quantitative results with qualitative findings. The study findings revealed that the
knowledge and information needs, and information seeking patterns of farmers were location and gender
specific. The major sources of information for farmers were predominantly local (neighbours, friends and
family). Most respondents indicated public extension as an important source of agricultural information. Private
extension services, village meetings and farmer groups were significant sources of information in some regions,

2
while printed information had low use. The role of ICTs in providing access to agricultural knowledge and
information, and the application of information and knowledge on farming systems in the rural areas of
Tanzania are also presented. The paper concludes with recommendations for improved access to agricultural
knowledge and information in the rural areas of Tanzania.
Keywords: agricultural knowledge and information, agricultural development, Tanzania
1. Introduction
An improved information and knowledge flow to, from, and within the agricultural sector are
a key component in improving small-scale agricultural production and linking increased
production to remunerative markets, thus leading to improved rural livelihoods, improving
quality and yield, food security and national economies (Asaba et al., 2006). The agricultural
sector is the backbone of many economies in Africa. In Tanzania, the economy depends
heavily on agriculture, which accounts for more than 25.7 percent of gross domestic product
(GDP), provides 30.9 percent of exports, and employs 70 percent of the work force (United
Republic of Tanzania, 2009). Various studies have revealed that there is a positive
relationship between the increased flow of knowledge and information and agricultural
development (Fawole, 2008).
However, most African countries have not devoted their efforts to the dissemination of
knowledge and information, especially in rural areas, where 70 to 80 percent of the African
population lives (Adomi et al., 2003). Only a small amount of agricultural information is
accessible to rural farmers, despite the large body of knowledge that exists in research
institutions, universities, public offices and libraries. This situation is largely attributed to the
weak linkages between research, extension, not for profit organizations, libraries and farmers
and thus these technologies have neither reached nor been adopted by their intended
beneficiaries to improve their farming activities in developing countries including Tanzania
(Tire, 2006). Thus, it was imperative to assess the accessibility of the agricultural information
and knowledge in the rural areas of Tanzanian.
The advancements in the information and communication technologies (ICTs) provide an
opportunity for developing countries to harness and utilize information and knowledge to
improve productivity in various sectors including agriculture (Lwoga & Ngulube, 2008).
Unfortunately, resource poor farmers are mainly affected by the digital divide which is a gap
between groups or individuals in their ability to use ICTs effectively due to differing literacy,

3
technical skills, and useful digital content (Ghatak, 2007). Nevertheless, the emergence of
low cost ICTs (such as radio, cell phones, and the media provided by the telecenters) may
bridge the digital divide (COSTECH, 2005). Given the fact that there are disparities to the
accessibility and utility of the ICTs especially for rural areas in the developed world contexts,
it is also important to investigate the application of these tools for the improved farming
activities especially in the rural areas. Thus, the assessment of the information needs, the role
of ICTs, and the access and use of knowledge and information in the rural areas were
pertinent issues to this study. Thus, the objectives of the study included the following:
- To establish the agricultural information needs of farmers in the study area;
- To find out how farmers accessed and used the agricultural information and
knowledge in the local communities;
- To assess how farmers accessed and used the agricultural information and knowledge
through ICTs in the local communities.
2. Methodology
This study used qualitative and quantitative methods. Six districts from six zones out of seven
research zones were selected for the study due to their high agriculture production and
presence of ICTs such as telecenters, community radio, and cellular phone networks. These
districts were Karagwe, Kasulu, Kilosa, Moshi Rural, Mpwapwa and Songea Rural. The
qualitative data was collected through the semi-structured interview items, focus groups, and
participatory rural appraisal (information mapping and linkage diagrams), while quantitative
data was gathered through closed questions which were embedded in the same semi-
structured interviews. Two villages were purposively selected from each of the six districts.
A total of 181 smallholder farmers participated in the semi-structured interviews, and the
respondents ranged between 27 and 37 farmers per region. A total of twelve focus group
sessions were held in the surveyed villages, and one focus group session was held per village.
The focus group discussion and interview data were studied and analyzed as they were
collected, until it was clear that perspectives were being repeated and data saturation had
been reached (Teddlie & Tashakkori, 2009). Both quantitative and qualitative data analyses
were kept separate, and then they were combined or integrated into meta-inferences (Teddlie
& Tashakkori, 2009). Some of the qualitative themes were also transformed into counts in
order to validate and compare quantitative and qualitative findings.

3. Research findings and discussions
This section presents study findings according to the following: information needs, access
and use of agricultural information and knowledge, and the role of ICTs in disseminating
agricultural knowledge and information. The respondent’s demographic characteristics are
also presented.
3.1 Profile of respondents
In the semi-structured interviews, 181 smallholder farmers participated, where 112 were men
and 69 were women. The mean age of the respondents was 48, where the majority of the
respondents 135 (74.6%) were between 29 to 68 years. The study mainly involved
smallholder farmers, with the average farm size of 4.9 acres, where the majority of the crop
farmers had farm sizes below 4.9 acres. Most respondents 152 (84%) had some level of
formal schooling and about 163 (91.2%) could read and understand simple instructions.
Among those with formal schooling, male respondents dominated the higher education
category as compared to female farmers.
For the focus groups, 128 smallholder farmers participated in the group discussions,
where 65 (50.8%) were male, and 63 (49.2%) were female. Twelve focus groups were held in
12 villages. The study participants for focus groups’ discussions ranged between six and
twelve respondents per session depending on their availability. The mean age of the
respondents was 45, where almost half of the respondents 62 (48.4%) were between 29 to 48
years. One hundred and fourteen (89.1%) respondents had some level of formal schooling
and 116 (90.7%) could read and understand simple instructions.
3.2 Farmers information and knowledge needs
The study findings showed that there was a large information and knowledge gap in the
surveyed communities. The major information and knowledge gaps identified in this study
related to control of plant diseases and pests 120 (66.3%), marketing 107 (59.1%), credit and
loan facilities 106 (58.6%), and control of animal diseases 99 (54.7%) (See Table 1). Further,
the findings indicated that knowledge and information needs varied across the surveyed
communities as shown in Table 1. The knowledge and information needs were location
specific due to slight variations in development, agricultural activities and agro-ecological
conditions in the surveyed communities. These findings were similar to other studies on

5
agricultural information needs in Kenya and South Africa (Wafula-Kwake & Ocholla, 2007),
and Tanzania (Matovelo et al., 2006).

(Multiple responses were allowed)
The study findings showed that there were slight variations in information needs according to
gender. Males needed knowledge on agricultural marketing 70 (62.5%), and soil fertility 57
(50.9%), while women needed knowledge on value added techniques 29 (42%), crop planting
25 (36.2%), and irrigation 23 (33.3%) as shown in Figure 1. Although the study findings
showed that there were slight variations in the information needs according to gender, other
studies carried out in Nigeria (Adomi, Ogbomo and Inoni 2003) reported that there was a
definite gender split in the information needs.

3.3 Access to agricultural information and knowledge in the surveyed communities
The study findings showed that neighbours/friends were the main sources of agricultural
information and knowledge in the local communities, with a score of 132 (72.9%)
respondents, followed by public extension officers 130 (71.8%) and parents/family 103
(56.9%) as shown in Table 2. Similar findings were observed in Nigeria (Adomi et al., 2003),
and Tanzania (Matovelo et al., 2006).
In this study, the extension officers were important sources of information and
knowledge, though farmers were dissatisfied with the frequency of their interactions, as it
was also found in Nigeria (Adomi et al., 2003), and Vietnam (Castella et al., 2006).
Agricultural input suppliers, village meetings, and farmer groups were important sources of
agricultural information and knowledge in some regions. Explicit sources of knowledge, with
the exception of books, had low use due to their unavailability and the absence of the reading
habit. This finding is consistent with the research findings observed in Nigeria (Adomi et al.,
2003) and South Africa (Mosia & Ngulube, 2005). Thus, there are still gaps in access to
information and knowledge which need to be strengthened.

(Multiple responses were possible)
Further, the tacit and explicit sources of knowledge varied across the districts as it
was found in another study in India (Conroy et al., 2004) (see Table 2). The findings suggest
the need to have flexible rural information provision strategies which can take account of
such variations.
The findings also indicated that there were variations in sources of knowledge
according to gender. Figure 2 shows that males dominated formal sources and explicit
sources of knowledge, while women dominated NGOs and local sources of knowledge.
Studies in India (Conroy et al., 2004) and Nigeria (Adomi et al., 2003) also showed that
women were frequently disadvantaged in accessing information and knowledge. Illiteracy
and cultural responsibility could be some of the factors which limited women’s access
information and knowledge.

(Multiple responses were possible)
It was clear from the information mapping and linkage diagrams that local and informal
contacts of parent/family, personal experience and neighbours / friends were the dominant
sources of knowledge in the local communities, followed by public extension officers (Figure
3). Village leaders, livestock headers, agricultural shops, NGOs, cooperative unions, farmer
groups, religious bodies, and middle men were important sources of knowledge in some local
communities. Explicit sources of knowledge were less considered as important sources of
knowledge in the communities.

3.4 Application of information and knowledge and technologies in farming systems
The study findings showed that 141 (77.9%) respondents had applied conventional
knowledge and techniques to their farming activities, while 40 (22.1%) had not. It was
evident from the findings that farmers mainly applied information and knowledge to crop
husbandry 87 (61.7%), and new varieties and techniques 50 (35.5%) as shown in Figure 4.
Improved agricultural production was the major reason for applying information and
technologies, especially on crop husbandry, control of plant and animal diseases, soil fertility,
new varieties and techniques, agricultural tools, and value added techniques, accounting for
133 (94.3%) respondents. The focus group discussions confirmed that improved agricultural
production was the major reason for applying information and technologies on crop
husbandry, new varieties and techniques, and improvement of soil fertility. These findings
show that the application of information and knowledge in the farming systems may also be
linked to increased production and income, and lack of indigenous skills and resources.

3.5 Access to agricultural information and knowledge through ICTs
One hundred and sixty one (89%) respondents used ICTs to access information and
knowledge, and the remaining 19 (10.5%) did not. Most farmers 155 (96.3%) used radio to
access information and knowledge on farming systems. ICTs used at the next highest rate
were cell phones 71 (44.1%) and television 64 (39.8%), while email 12 (7.5%), internet 9
(5.6%), film shows, eight (5%), and video cassettes, six (3.7%) were used at a low rate.
Findings from Nigeria (Adomi et al., 2003) and Tanzania (Chilimo, 2009) showed that few
farmers had used internet and email services for knowledge acquisition. The study findings
indicate that the mass media and interpersonal channels were the major sources of
agricultural information and knowledge in the local communities.
The information mapping confirmed that radio was the principal ICT used by farmers to
access knowledge as indicated in Figure 3. Television and cell phones were important tools
used by farmers to access information and knowledge in some locations, while advanced
ICTs such as Internet and email were less used to access agricultural information and
knowledge in the surveyed communities.
3.6 Application of agricultural information and knowledge through ICTs
The study findings established that the majority of the respondents applied information and
knowledge, with 141 (77.9%) receiving it from tacit and printed sources of knowledge in the
farming systems and 64 (35.4%) obtaining it from ICTs. These findings show that oral
communication channels were regarded as effective ways of delivering information and
knowledge in the surveyed local communities to a greater extent than ICTs. Similary,

Chapman et al., (2003) found that the use of participatory communication techniques and
indigenous communication channels (such as drama) utilizing local languages and rural radio
had some influence on the majority of the farmers regarding their decisions whether or not to
cut down trees and to discontinue bush burning on their farms. Indications are that the
combination of participatory techniques, indigenous communication channels and ICTs can
improve the sharing and adoption of agricultural technologies in the local communities.
The present study established that the crop husbandry techniques 31 (48.4%) were the
major adopted technique that were received through ICTs in the local communities, followed
by new techniques and varieties 21 (32.8%), and improvement of soil fertlity 15 (23.4%).
Other adopted techniques through ICTs were control of plant diseases and pests 8 (12.5%),
and control of animal diseases, seven (10.9%). Few farmers applied knowledge on
agricultural tools, five (7.8%), livestock husbandry, one (10.9%) and value added, one
(1.6%).
The major reasons for adopting the agricultural information and technologies were
improved crop and animal production 63 (98.4%). These findings were similar to the major
reasons for adopting information and knowledge from tacit and printed sources of knowledge
in the surveyed communities. Indications are that ICTs can also play a key role in providing
access to relevant and effective information and knowledge which can improve agricultural
productivity and increase income in the local communities.
4. Conclusions and recommendations
From the above research findings, it can be concluded that access to relevant information and
knowledge is very important to improve the agricultural performances and livelihoods in the
rural areas especially in African countries. However, the findings revealed that there was a
large information and knowledge gap in the sampled districts because the rural information
provision services were not driven by the farmers’ needs in the surveyed communities. The
findings also suggest that farmers will continue to rely on face to face communication and
probably radio and cell phones more than printed materials and advanced ICTs such as
internet and email to access information and knowledge in the communities for improving
their farming activities. Based on the findings, the following recommendations are made:
 Rural knowledge provision strategies should conduct regular studies on information
and knowledge needs, and involve farmers in the design and development of

12
agricultural technologies to increase the adoption rate of information and
technologies; and
 The establishment of community radio that uses vernacular languages, and indigenous
communication mechanisms (such as drama, storytelling) should be encouraged in the
local communities in order to disseminate relevant knowledge to farmers.
For further studies, this paper recommends that research be undertaken to establish the role of
community radio, cell phones and television in managing and integrating indigenous and
external knowledge for effective agricultural practices in the local communities. The linkages
between face to face communication and ICTs need to be investigated for effective
agricultural performances in the African countries.
