Sustainability of rural water services in rural Sub-Saharan Africa environments: developing a Water Service Sustainability Index

Application of the Water Service Sustainability Index to water services in sub-Saharan Africa: the case studies of eight councils in the Southern region of Cameroon (Central Africa)

“…Dimensions and indicators are the main constituents of the WSSI. They were selected through a literature review on existing evaluation frameworks (Mvongo et al 2021b). The WSSI final framework has 21 indicators grouped into six dimensions (economic, technical, environmental, governance, social, and institutional).…”

“…The participatory approach was used to weighting dimensions and indicators in light of the fact that it directly involves all stakeholders involved in water service management (Mvongo et al 2021b). The AHP was used because of its simplicity.…”

“…vectors, and the determination of the index and consistency ratio (Mvongo et al 2021b). Table 1 summarizes the dimensions and indicators with their corresponding weights.…”

“…The interpretation of the WSSI is made on the basis of the quartile scale (Mvongo et al 2021b). This method provides for four levels of performance with a maximum value of 100 and a minimum value of 0, as shown in Table 2.…”

“…A new water sustainability index, called Water Service Sustainability Index (WSSI), was recently developed using multicriteria analysis and the AHP by Mvongo et al (2021b) in order to allow an integrative, contextualized, and prospective analysis of the sustainability of water service in the rural area. This was specifically developed with the involvement of local water stakeholders and based on the Mvila Division's natural and socioeconomic characteristics.…”
