LAND DEGRADATION AS A COMPLEX STABILITY PROBLEM

LAND DEGRADATION AS A COMPLEX STABILITY PROBLEM

This paper reviews recent work in the fields of ecology and economic ecology that contribute to a better understanding of the grazing and erosion debate. The approach is through dynamical systems models represented by differential equations and expressed by the phasespace diagrams for systems. The t...
