Correction to “Modeling how and why aquatic vegetation removal can free rural households from poverty-disease traps,” by Molly J. Doruska, Christopher B. Barrett, and Jason R. Rohr, which published December 17, 2024; 10.1073/pnas.2411838121 (Proc. Natl. Acad. Sci. U.S.A. 121, e2411838121).
The authors note that Figs. 2–5 appeared incorrectly. They have been replaced with higher-resolution figures to ensure legibility of the axis values and labels.
Fig. 2.
Median vegetation load, infection rate, labor availability, fertilizer use, and income for simulations with and without vegetation harvest. Panel (A) plots the median aquatic vegetation stock (population) in metric tons across 1,000 20-y simulations for three different household land endowments with (solid lines) and without (dashed lines) vegetation harvest. Aquatic vegetation load represents the size of the snail habitat within the village water access point used by the household. Shaded areas represent the 5 to 95 percent centered confidence band. Based on scale and precision, not all shaded areas are visible. Panel (B) shows the median household infection rate (the number of infected individuals divided by total number of household members). Panel (C) reports median labor availability from the 10-person household size maximum. Panel (D) displays median fertilizer use in kgs per hectare, and Panel (E) reports the median income in FCFA1,000. Medians and percentiles are within each land endowment each time period across the 1,000 simulations.
Fig. 3.
Median first year optimal fertilizer use at different infection levels. This figure plots median fertilizer use in kgs per hectare in the first year across 1,000 20-y simulations for the median household land endowments with vegetation harvest. Shaded areas represent the 5 to 95 percent centered confidence band. Only the initial starting infection probability was modified. All other disease ecology submodel parameters remain the same.
Fig. 4.
Median vegetation load, infection rate, labor availability, fertilizer use, and income for the fertilizer effect sensitivity analysis. Panel (A) plots the median aquatic vegetation stock (population) in metric tons across 1,000 20-y simulations for four different levels of feedback between fertilizer runoff and vegetation growth () and households with two hectares of land. Aquatic vegetation load represents the size of the snail habitat within the village water access point used by the household. Shaded areas represent the 5 to 95 percent centered confidence band. Based on scale and precision, not all shaded areas are visible. Panel (B) shows the median household infection rate (the number of infected individuals divided by total number of household members). Panel (C) reports median labor availability from the 10-person household size maximum. Panel (D) displays median fertilizer use in kgs per hectare, and panel (E) reports the median income in FCFA1,000. Medians and percentiles are within each land endowment each time period across the 1,000 simulations.
Fig. 5.
Median vegetation load, infection rate, labor availability, fertilizer use, and income for the vegetation growth rate sensitivity analysis. Panel (A) plots the median aquatic vegetation stock (population) in metric tons across 1,000 20-y simulations for three different levels of the vegetation growth rate () and households with two hectares of land. Aquatic vegetation load represents the size of the snail habitat within the village water access point used by the household. Shaded areas represent the 5 to 95 percent centered confidence band. Based on scale and precision, not all shaded areas are visible. Panel (B) shows the median household infection rate (the number of infected individuals divided by total number of household members). Panel (C) reports median labor availability from the 10-person household size maximum. Panel (D) displays median fertilizer use in kgs per hectare, and Panel (E) reports the median income in FCFA1,000. Medians and percentiles are within each land endowment each time period across the 1,000 simulations.
