Reviewing Key Challenges of Collaborative Governance Dynamics in Subnational REDD+ Implementation Across the Global South Through the Integrative Framework for Collaborative Governance

Abstract

The international policy framework for “Reducing Emissions from Deforestation and Forest Degradation, plus the conservation, sustainable management of forests, and enhancement of forest carbon stocks” (REDD+) is a vital United Nations Framework Convention on Climate Change (UNFCCC) mechanism designed to assist Global South nations in reaching their climate goals under the Paris Agreement. Implementable at the project, subnational, and national levels, REDD+ has placed an increasing emphasis on subnational program implementation in recent years, exemplified by a growing focus on jurisdictional and integrated landscape strategies. These comprehensive approaches balance diverse land uses and address the complex causes of deforestation through economic incentives and multi-level, cross-sector planning at the state, provincial, or district levels. Ultimately, successful implementation depends on collaboration, active stakeholder engagement, resources, mutual trust, and adequate institutional capacity to manage conflicting local interests. However, weak forestland-use governance in many countries of the Global South often results in inefficient collaborative dynamics that hinder stakeholder cooperation. Despite this, the specific collaborative challenges hindering stakeholder collaboration in subnational REDD+ implementation remain insufficiently understood. To address this gap, this study conducts a literature review to systematically synthesize evidence on subnational REDD+ implementation, using the Integrative Framework for Collaborative Governance (IFCG) to identify key knowledge gaps and challenges. Following established methodological guidance, six databases were searched, Scopus (824), Web of Science (1347), PubMed (84), ResearchGate (557), Google Scholar (571), and Research Rabbit (191), yielding 43 articles on subnational REDD+ implementation for inclusion in the synthesis. The findings identify four main challenges: (i) system context-related challenges, (ii) burdensome global requirements, (iii) resource constraints, and (iv) challenges inherent in the institutional design of collaborative arrangements. While the IFCG proves analytically useful, the complexity and evolving nature of subnational REDD+ programs complicate its application, revealing areas for theoretical refinement. By critically examining the IFCG’s utility, this study advances collaborative governance theory and offers empirical insights into the conditions necessary for effective stakeholder collaboration in subnational REDD+ implementation across the Global South.
