Fig. 5

Below we model the production paradigm \((E_0 = -0.09; P_0 = 1; a = 0.3; b = 0.01; c = 0.1; k = 0.1;)\) with solid lines and the access paradigm \((b = 100; k = 0.4;\) all other parameters the same) with dotted lines. The production paradigm assumes a more resilient food system with a lower b parameter, but also a lower transportation value with a lower k parameter. a This plot shows the equilibrium values of each paradigm. Maximum production is noticeably less but stable in the production paradigm. b This figure shows how the human population evolves over time in the center village, Village\(_0\). In the access paradigm, loss of life is completely averted, but in the production paradigm, \(~10\%\) loss in population is experienced. In all other villages for each paradigm, the populations are unchanged. c This figure displays how excess food produced changes over time for Village\(_0\) in red and Village\(_1\) in blue. In both paradigms, the food production systems return to equilibrium after 1 season
