A QUANTITATIVE APPROACH TO PREDICT ... - SuSanA

agricultural produce and also consumers may not be willing to buy produce fertilized
with co-compost. 55 To be specific with what Cofie and Doulaye said an example is
given based on the study of Danso et al 56 which focused on estimating the demand for
municipal wastes via willingness-to-pay in Ghana. The study concentrated on three
cities in Ghana namely Accra, Kumasi and Tamale. This research came with the
findings that only 20% of the respondents expected the co-compost from the solid waste
and excreta to be ineffective by considering health, cultural and religious
consequences. 57
Concerning the willingness to pay, the urban farmers in Kumasi were willing to pay less
as compared with their counterparts in the peri-urban communities due to their access to
free poultry manure. The situation was similar in Accra where the peri-urban farmers
were willing to pay more. However, in the case of Tamale, the urban farmers were
willing to pay more than the peri-urban farmers since their access to animal manure was
limited. 58 Further analysis of the study showed that variables like perception, level of
education, age, experience with compost and income levels were significant in
determining the willingness to pay of the farmers. To market the co-compost, the
research came to the conclusion that it will be more effective if the compost production
is more subsidised so that farmers will be able to pay for the transport cost as well. 59
The paper of Cofie and Doulaye with the study of Danso et al like that of Nkansa-
Boadu, focused more on economic aspect which is different from the focus of this paper
where the author want to outline factors that determine intentions towards the usage of
the ecosan fertilizer which is from the socio-psychological point of view. Moreover,
this research focus specifically on farmers who are aware of excreta based fertilizer but
are not using it to determine if apart from the economic issues, other factors influence
their willingness to use the ecosan fertilizer.
In relation to the determination of factors that influence the reuse of wastes as done by
Danso et al, Ekere et al 60 undertook a study on factors that influence the separation and
utilization of biodegradable wastes in the Lake Victoria Crescent in Uganda from the
