Qualitative analysis of water insecurity in Mali

According to the PLOS Water study "Beyond infrastructure: Linking multiple-use water services and experiences with household water insecurity in rural Mali" (published August 4, 2026), year-round MUS is associated with lower household water insecurity while seasonal MUS is associated with higher insecurity. Beyond infrastructure: Linking multiple-use water services and experiences with household water insecurity in rural Mali.

• The PLOS Water survey covered 1, 082 households in Mopti and Sikasso, Mali, with data collected between February and April 2021 and 1, 069 complete cases used in regression models, according to Stellbauer et al. (2026).
• According to Stellbauer et al. (2026), the mean HWISE score in the sample was about 5 and 85–95% of households reported access to an improved water source during the survey period.
• According to the PLOS Water results, year-round MUS households had HWISE scores about two points lower (roughly a 40 percent reduction relative to the sample mean) while seasonal MUS households had HWISE scores about three points higher (roughly a 25–30 percent increase), as reported in August 2026.
• According to the PLOS Water authors, "MUS is not a panacea for household water insecurity, " and "MUS is not inherently protective against water insecurity, " highlighting the study's cautionary conclusion.

Answer: According to the PLOS Water article, the study surveyed 1, 082 rural households in Mopti and Sikasso, Mali between February and April 2021 and used the 12-item HWISE scale to measure experiential household water insecurity.

According to Stellbauer et al. (2026), households were classified as year-round MUS, rainy-season-only MUS, dry-season-only MUS, or non-MUS using irrigation and domestic-use proxy variables derived from the household survey.

According to the PLOS Water methods section, the HWISE composite score ranges from 0 to 36 and the authors analyzed it and four subdomains (worry, hygiene, access, interruption) using multiple linear regression in Stata/MP 17.0 with 1, 069 complete observations.

According to the PLOS Water results, year-round MUS correlated with significantly lower HWISE scores while seasonal MUS correlated with higher HWISE scores; the authors emphasize these are associations, not causal claims.

According to the PLOS Water discussion, seasonality and reliability underpinned the observed associations and the authors recommend pairing infrastructure measures with experiential tools like HWISE when evaluating water services.

Answer: According to the PLOS Water study, qualitative researchers should measure seasonality, service reliability, and experiential outcomes (HWISE) alongside infrastructure to avoid misclassifying water security.

According to Stellbauer et al. (2026), simply asking about a household's "main" source risks overlooking source-switching and seasonality which more than one indicator can reveal.

• Design: According to the PLOS Water authors, collect data across seasons (for example, sample rounds in both rainy and dry seasons) to capture shifting MUS practices and source-switching.
• Measurement: According to the PLOS Water methods, combine the 12-item HWISE scale with open-ended interviews probing why households switch sources, perceptions of reliability, and coping strategies.
• Sampling: According to the PLOS Water analysis, record irrigation status and source type to construct MUS categories (year-round, rainy-only, dry-only) rather than relying on a single infrastructure label.
• Analysis: According to the PLOS Water findings, analyze HWISE subdomains (worry, hygiene, access, interruption) separately to surface nuanced experiential impacts that aggregate scores can mask.

According to the PLOS Water study, year-round MUS is associated with materially lower household water insecurity while seasonal MUS signals vulnerability tied to availability and reliability; practitioners should therefore pair HWISE-style experiential measures with seasonal qualitative data.

According to the PLOS Water authors, program design should prioritize continuity of supply, dry-season storage, and targeted water treatment during rainy-season reliance on surface sources.
