Fig. 3. Viability kernels for an hysteretic lake (b = 0.8). The set of state constraints, K = [Lmin; Lmax] × [0; Pmax], is bordered by a black rectangle. Lmin = 0.1, Lmax = 1, Pmax = 1.2 and VLmax takes increasing values. Viab(K) is colored light gray. The viability niche N(0), which is contained in the viability kernel, is white.
