Abstract

In a fallow-cultivation model with biomass regeneration, we find the population-poverty-degradation linkage via the discount rate: slight increases in the discount rate result in increased cropping frequency and much lower soil fertility. Aggregating gives transitions equation declining in fertility and increasing in the fallow:cultivation ratio.
