The Resource Nexus concept has evolved significantly over the past decade, with numerous literature reviews contributing to the understanding of its development and application. This paper aims to validate the Resource Nexus concept for research and practice by conducting a systematic review of existing reviews and consulting with sixty nexus experts. The study suggests a robust yet flexible approach to advancing the Resource Nexus, integrating scientific research with policy-making and community practices. The Resource Nexus considers the interconnectedness of natural resources and their management, aiming to support sustainable development through integrated resource management. The paper identifies key features of the Resource Nexus, including its interdisciplinary nature, the interlinkages between different environmental resources, and the need for integrated policy frameworks. It highlights the importance of considering multiple dimensions such as governance, stakeholder involvement, and the spatial and temporal scales of resource management. The study also addresses the gaps and challenges in understanding the Resource Nexus, including conceptual, operational, and contextual issues. These include the need for a common conceptual framework, the development of appropriate tools and models, and the inclusion of governance and stakeholder perspectives. The paper proposes a typology of components and drivers of the Resource Nexus, emphasizing the need for a conceptual model that integrates the complex interlinkages between environmental resources. It also discusses the importance of a parsimonious approach in defining the Resource Nexus, focusing on the simplest and most effective explanations. The study concludes that the Resource Nexus offers a comprehensive approach to managing environmental resources, promoting cooperation and coordination across sectors and institutions. It emphasizes the need for further research and development to address the challenges and improve the implementation of the Resource Nexus concept.The Resource Nexus concept has evolved significantly over the past decade, with numerous literature reviews contributing to the understanding of its development and application.
