The Case for Strategic Data Stewardship: Re-imagining Data Governance to Make Responsible Data Re-use Possible

TL;DR

The paper advocates for strategic data stewardship as a new approach to data governance that promotes responsible, cross-sector data reuse to address societal challenges and foster collaboration in the age of AI.

Contribution

It introduces the concept of strategic data stewardship, outlining principles, functions, and a practical Data Stewardship Canvas to enhance data mobilization and trust across ecosystems.

Findings

Strategic data stewardship enables more effective data reuse.

The Data Stewardship Canvas supports adoption in various data contexts.

Implementing strategic stewardship fosters trust and collaboration.

Abstract

As societal challenges grow more complex, access to data for public interest use is paradoxically becoming more constrained. This emerging data winter is not simply a matter of scarcity, but of shrinking legitimate and trusted pathways for responsible data reuse. Concerns over misuse, regulatory uncertainty, and the competitive race to train AI systems have concentrated data access among a few actors while raising costs and inhibiting collaboration. Prevailing data governance models, focused on compliance, risk management, and internal control, are necessary but insufficient. They often result in data that is technically available yet practically inaccessible, legally shareable yet institutionally unusable, or socially illegitimate to deploy. This paper proposes strategic data stewardship as a complementary institutional function designed to systematically, sustainably, and responsibly activate data for public value. Unlike traditional stewardship, which tends to be inwardlooking, strategic data stewardship focuses on enabling cross sector reuse, reducing missed opportunities, and building durable, ecosystem-level collaboration. It outlines core principles, functions, and competencies, and introduces a practical Data Stewardship Canvas to support adoption across contexts such as data collaboratives, data spaces, and data commons. Strategic data stewardship, the paper argues, is essential in the age of AI: it translates governance principles into practice, builds trust across data ecosystems, and ensures that data are not only governed, but meaningfully mobilized to serve society.
