In this study, we investigate a fast algorithm for the fractional-order nonlinear multi-agent system with time-varying delay. Firstly, we develop a Lyapunov function to analyze the stability of the system. Then, we apply the L1 formula for the time-fractional derivative and demonstrate the stability and convergence of the constructed scheme through mathematical induction. Next, we use the preconditioned conjugate gradient method to solve the discretised linear numerical scheme.

As agrifood systems contribute considerably to global greenhouse gas emissions, policies targeting greenhouse gas reductions must navigate the distributional and dynamic implications of induced food price effects. Marketing margins can buffer consumer prices from production cost increases, but those effects vary across countries in ways that complicate the political economy of corrective policy.
