Abstract for: A Biomass–Water Nexus Perspective on Sustainable Agricultural Resource Management: A System Dynamics Research Program Integrating Evolutionary Games

In China, the annual output of livestock and poultry manure exceeds 3.8 billion tons while effective resource utilization remains below 60%, and large volumes of crop/forestry residues face collective-action barriers across collection–transport–processing–reuse chains. Meanwhile, agricultural water scarcity and regional imbalance interact with crop-specific water demand patterns and rising climate extremes. This paper synthesizes a system dynamics (SD) research program that addresses these challenges through an integrated “Biomass–Water Nexus” governance lens, structured around three research streams: (1) livestock waste management and resource utilization, (2) crop/forestry residue circular utilization and organizational coordination, and (3) agricultural water allocation, coordination, and decision support. Across applications, the program reveals recurring dynamic archetypes (e.g., limits-to-growth and path dependence), clarifies leverage points that shift governance from administrative control to market-driven coordination (e.g., carbon trading incentives, bonus allocation rules, and platform governance), and provides a unifying modeling framework for cross-resource, cross-actor, and cross-scale policy design. A common dynamic grammar: reinforcement, constraint, delay, and diffusion. Governance transitions require mechanism design, not only regulation intensity. Method integration is not cosmetic—it changes what can be asked and answered.
