As the sustainability of agricultural citizen science projects depends on
volunteer farmers who contribute their time, energy and skills,
understanding their motivation is important to attract and retain
participants in citizen science projects. The objectives of this study
were to assess 1) farmers' motivations to participate as citizen
scientists and 2) farmers' mobile telephone usage. Building on
motivational factors identified from previous citizen science studies, a
questionnaire based methodology was developed which allowed the analysis
of motivational factors and their relation to farmers'
characteristics. The questionnaire was applied in three communities of
farmers, in countries from different continents, participating as citizen
scientists. We used statistical tests to compare motivational factors
within and among the three countries. In addition, the relations between
motivational factors and farmers characteristics were assessed. Lastly,
Principal Component Analysis (PCA) was used to group farmers based on
their motivations. Although there was an overlap between the types of
motivations, for Indian farmers a collectivistic type of motivation (i.e.,
contribute to scientific research) was more important than egoistic and
altruistic motivations. For Ethiopian and Honduran farmers an egoistic
intrinsic type of motivation (i.e., interest in sharing information) was
most important. While fun has appeared to be an important egoistic
intrinsic factor to participate in other citizen science projects, the
smallholder farmers involved in this research valued 'passing free
time' the lowest. Two major groups of farmers were distinguished: one
motivated by sharing information (egoistic intrinsic), helping (altruism)
and contribute to scientific research (collectivistic) and one motivated
by egoistic extrinsic factors (expectation, expert interaction and
community interaction). Country and education level were the two most
important farmers' characteristics that explain around 20% of the
variation in farmers motivations. For educated farmers, contributing to
scientific research was a more important motivation to participate as
citizen scientists compared to less educated farmers. We conclude that
motivations to participate in citizen science are different for
smallholders in agriculture compared to other sectors. Citizen science
does have high potential, but easy to use mechanisms are needed. Moreover,
gamification may increase the egoistic intrinsic motivation of farmers. Motivation of
smallholder farmers to participate in citizen scienceThe data file provides
the motivational factors for farmers to participate in citizen science. It
is measured in Likert scales with the values 1 (“Not important at all”), 2
(“Not important”), 3 (“Neutral”), 4 (“Important”) and 5 (“Very
important”).Beza_et.al_2017_MotivationData.csv
