• Field openers should be admired for leading the crowds. This comment is relevant to the bigger picture of Professor Sourirajan to highlight how a humble talent had selflessly founded a multicontinental major, which scaled up to US$ 50 billion in the 2021 global membrane separation market to enrich the quality of worldwide life via providing clean water.

  • Deductive arguments regarding the unexpected stability of nanobubbles in water include the excessive internal pressure of minuscule gas pockets. In this study, the derivation assumptions of the Young–Laplace equation are evaluated closely to discuss the possible modifications towards making conclusive remarks about the predictive power of the equation at the nano-scale.

  • Climate resilient development has become the new paradigm for sustainable development influencing theory and practice across all sectors globally—gaining particular momentum in the water sector, since water security is intimately connected to climate change. Climate resilience is increasingly recognised as being inherently political, yet efforts often do not sufficiently engage with context-specific socio-ecological, cultural and political processes, including structural inequalities underlying historically produced vulnerabilities. Depoliticised approaches have been shown to pose barriers to concerted and meaningful change. In this article, world-leading water specialists from academic and practitioner communities reflect on, and share examples of, the importance of keeping people and politics at the centre of work on climate resilient water security. We propose a roadmap to meaningfully engage with the complex politics of climate resilient water security. It is critical to re-politicise climate resilience to enable efforts towards sustainable development goal 6—clean water and sanitation for all.
