| description | The fundamental objective of discrete Choice Experiments (CEs) model or Choice Modelling (CM) is to understand
the behavioural processes among individuals which drive the choice decisions based on selected attributes and
choice options. Preferences may differ among individuals triggered by their specific characteristics such as sociodemographics,
constraints and attitudes. Preferences could also vary among groups and within a particular group by
forming different segments of groups or subgroups. The Latent Class (LC) model is a distinctive approach which can
accommodate preference heterogeneity where preferences are assumed to be relatively homogenous within the segments,
but substantially different between the segments. This LC model was applied to account for preference heterogeneity
among aquaculturists in the Setiu Wetlands, Terengganu. Currently, fish cage culture is the main socio-economic activity
which imposes considerable impacts on the wetland ecosystem and thus affect its ability to deliver ecosystem service
outcomes to other stakeholder groups. This research quantifies the aquaculturists’ preferences heterogeneity with regard
to the ecosystem impacts under different management scenarios. The existence of sub-divisions of preferences within the
stakeholder subgroups was tested. This study revealed three latent classes or segments which show relatively distinct
sets of preferences. Segment 1 shows a strong preference for higher harvest rates, a moderately strong preference
for higher fisheries income and a moderately strong preference for lower shellfish collections. Segment 2 shows a
moderately strong linear preference for higher harvest rates and a very strong preference for retaining the status quo.
Segment 3 shows a perplexing set of significant preferences for increasing harvest rates and a modest preference for
higher fisheries income. In direct contrast to Segment 2, Segment 3 shows a very strong aversion to retaining the status
quo. The results of aquaculturists’ preferences for delivery of different ecosystem services in Setiu Wetlands suggest
that Latent Class Model (LCM) could be applied successfully in a Malaysian setting. The success of the LC model is
evidenced by the high level of fit obtained from the best fitting models. The main finding of this research suggests that
a good understanding of the main research objective, familiarity with the research area and carefully designed choice
set, as well as employing appropriately trained enumerators are the main factors that particularly contribute to a
successful application of the LC model in a developing country setting. |
