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

Figure 9

Phase portrait corresponding to the disappearing of forage resources and water resources and removal of the pastoralists with their herds for System (2). We can observe here the global asymptotic stability of 𝐸₁₀=(0,0,0) when 𝑟₁=−0.4<0 and 𝑟₂=−60<0. The rest of parameters are in Tables 1 and 2.
