<p>Water scarcity in Jordan is among the most severe globally, yet its social and gendered dimensions remain underexplored. This study examines how women’s knowledge, attitudes, and practices shape water sustainability through a gender -sensitive theoretical approach grounded in gendered water governance, sustainability and stewardship literature. Drawing on twenty-seven semi-structured interviews with women and institutional stakeholders, the research adopts a qualitative interpretivist approach. The findings reveal that women’s knowledge of water scarcity in Jordan is deeply experiential and multi-dimensional, integrating both normative values—such as moral, cultural, and religious obligations to conserve water—and instrumental understandings shaped by the country’s political, economic, and technological realities. Despite their central role in managing household water, women remain marginalized in decision-making and excluded from governance structures. The study argues that recognizing women’s stewardship—an ethic of care, reciprocity, and responsibility—can advance gender-inclusive water governance and sustainable development goal 6 (clean water and sanitation). By amplifying women’s lived experiences, this paper redefines sustainability as both a normative and instrumental project, grounded in equity, justice, and everyday practice.</p>
