Abstract for: Multisystem Interactions and Tipping Points: A System Dynamic Approach to Accelerate Sustainability Transitions

Sustainability transitions must accelerate to address climate change, inequality, and biodiversity loss. However, acceleration is under-theorised, tipping points lack operational clarity, and multi-system interactions are not well-integrated. Existing frameworks fail to capture their interdependence. There is a need for a unified conceptual and analytical model—like system dynamics—to better understand and guide systemic change, especially in Global South contexts. How can tipping points and multi-system interactions accelerate sustainability transitions? Key enablers include reinforcing feedback, critical mass, policy support, and system alignment. Tipping points involve thresholds, self-reinforcing loops, and feedback like cascades and network effects. Challenges remain in cross-scale coordination and ensuring equity. A strategic, integrated approach is essential to unlock acceleration in complex socio-ecological systems. This study makes a unique contribution to the field of sustainability transitions by exploring the dynamics of tipping points and multisystem interactions through the development of a system dynamics model. Focusing on the Global South case study, the model is adjusted to incorporate the unique challenges, opportunities, and factors in developing regions, thereby enhancing our understanding of sustainable development. The potential impact of this study is significant, as it could provide insights into facilitating and accelerating sustainability transitions in specific systems and regions. The model incorporates linear and non-linear dynamics, feedback loops, and interventions. Empirical data from the case study are used to adjust and validate the model after identifying key tipping points and interactions in the system.
