A Transdisciplinary Framework to Bridge Science–Policy–Development Gaps in Global Land Management Initiatives

The effective implementation of Sustainable Land Management (SLM) remains a global challenge due to its weak integration across science, policy, and development practice. This study proposes a transdisciplinary framework to address soil erosion through SLM, based on global analyses of soil erosion risk and SLM research, policy, and practices at the country level. Using indices of policy-development, science-policy, and science-development interfaces, the study evaluates the science–policy–development interface (SPDI) in 236 countries. Findings indicate that over 190 countries (81%) face moderate or high soil erosion risk, while 182 countries (77%) have a SPDI level below their erosion risk, underscoring the urgent need for a comprehensive framework. The proposed seven-stage transdisciplinary framework, ranging from shared research framing to ex-post evaluation, aims to enhance SLM implementation and support soil erosion mitigation efforts. Its practical application, illustrated through a recent project, highlights the necessity of country-specific studies to tailor effective frameworks for sustainable land management.
