摘要：The main objective of this essay is to analyze how the rise of perspectives towards dryland environments challenges traditional ideas about ecological dynamics. To reach that goal, the essay is divided in three sections: the first part analyzes the characteristics of ecology systems and the way in which dryland environments challenge the traditional concepts of loading capacity, the area-biodiversity postulate and the biodiversitystability postulate. The second part will analyse the rise of "new ecology" and how concepts from non-equilibrium ecology diverge from those in the conventional ecology systems. The third part considers some features of dryland environments in which this conceptual shifting has been evident; this part highlights the ecological postulates adopted on policy design and implementation regarding management, administration and support for dryland environments.
