Outcomes were evaluated across contexts by altering key assumptions to simulate system deployment in five countries of interest (China, India, Senegal, South Africa, and Uganda). Key drivers of system sustainability were identified through uncertainty (Monte Carlo simulation) and sensitivity (Spearman's rank correlation coefficients) analyses. Lastly, carbon and nutrient balances for each scenario were evaluated to quantify the potential of these resources to offset sanitation deployment costs through carbon sequestration credits and fertilizer sales.
