Abstract
Wetland degradation has recently received considerable attention in research.
Although wetlands are valuable ecosystems, their actual value is difficult to
measure because the services they provide do not have market values. The
current study tries to define the value of wetlands in the Kilombero Valley,
central Tanzania. Choice modelling is used to determine communities’
preferences over wetland conditions associated with various management
options. The results show that the inhabitants of the Kilombero Valley desire
improvements in the wetland’s conditions, suggesting that the ongoing
degradation is not socially optimal. Local farmers are however highly dependent
on the wetland for their livelihood. In order to reduce pressure on wetlands, it is
therefore necessary and imperative to explore the options of alternative income
generating activities and the application of proper technologies to improve
efficiency and effectiveness in crop production.
Keywords: wetlands, choice modelling, valuation and willingness to pay.
1 Introduction
In recent years, degradation of wetlands has received considerable attention in
research. While in the past, wetlands were mostly neglected because they were
considered as marginal areas, authors like Fischer [1] and Turner et al. [2] have
recognized their importance. Wetlands play a unique role as ecosystem and
provide diverse services to communities such as climate regulation, flood control
and provision of food and fiber. To preserve the functions played by wetlands a
sustainable management is of paramount importance. One of the prerequisites for
