With the agreement of all co-authors, corrections have been made to this article [1] to ensure proper attribution of collaborative contributions and compliance with academic integrity standards. The changes are as follows:

1. Main Text Corrections

Section 6.8, first paragraph, fourth sentence, corrected to: “During the colonial period (e.g., up to the 1950s/1960s), RWH was a common strategy for urban water supply in Africa, Asia, and South America [126,204,205].”

Section 6.10, first paragraph, second sentence, corrected to: “This sectorial approach has presented many deterministic and stochastic models that have subsequently been corrected or invalidated [7,81,82,212–214]. Despite the global application of IWRM using various models and concepts, simultaneously addressing water scarcity (e.g., infiltration, storage) and water-related risks (e.g., erosion mitigation, flood control) under changing climate and land-use conditions is still difficult. Even the One Water Concept [59,61,215], which recognizes that drinking water, stormwater, and wastewater are a single, interconnected resource, contains an oversight [62,216]. A common oversight in past efforts is that they have attempted to use observations to infer models [92]. However, it is the essence of science that such endeavours cannot be successfully carried out. Most of the models, if not all, have been invalidated by field observations [19,34,214].”

Section 7.4, second paragraph, fourth sentence, corrected to: “and (iii) introducing rainwater harvesting into the scholar curriculum, particularly in developing countries [219,238–240].”
