TL;DR
The paper tackles the challenge of groundwater management in a water-stressed Tunisian region by merging Problem Structuring Methods (cognitive maps and value trees) with Concept-Knowledge (CK) design theory through the P-KCP framework. It translates stakeholder perspectives into a value tree (knowledge space) and then into a concept space (C-tree) to generate innovative, participatory policy alternatives, demonstrated in the Limaoua case. The study yields a replicable, context-adaptive process that fosters stakeholder collaboration and produces actionable governance options, such as a community groundwater development area (GDA). This integrative approach advances both decision science and design theory and offers a practical blueprint for participatory policy design in complex, multi-stakeholder resource settings.
Abstract
Groundwater management, especially in regions like Tunisia, is challenging due to diverse stakeholder interests and the dry structure of climate, which is extremely challenging for the sustainability of water resources. This paper proposes an innovative approach to policy design by merging Problem Structuring Methods (PSMs) and the Policy-Knowledge, Concepts, Proposals (P-KCP) methodology. Utilizing cognitive maps and value trees, the study aims to generate new collective groundwater management practices. Bridging decision theory and design theory, the study addresses the gap in new alternative generation and highlights the P-KCP's role in innovative policy design. Integrating PSMs and C-K theory, the framework expands policy alternatives and advocates for participatory approaches. It emphasizes adaptability across contexts, provides replicable process descriptions, and encourages the creation of unconventional policy solutions. Ultimately, this comprehensive framework offers a practical guide for policy innovation and collaboration.
