Dynamical Models of Interactions between Herds Forage and Water Resources in Sahelian Region

Figure 11

Illustration of periodicity of the trajectories at equilibrium 𝐸₂=(𝑅^∗,𝑊^∗,𝐻^∗) for System (2). Alternative peaks are observed between the trajectories of the flock, feed resources, and water resources when 𝑟₁=800 kgDM/ha, 𝑟₂=700 kgDM/ha, 𝑝=600mm, 𝐾₁=1000 kgDM/ha, and 𝐾₂=900 kgDM/ha. The rest of parameters are in Tables 1 and 2.
