Aim/objectives/study area-framework • To validate the theory one desert spp and it is Eco zone were chosen to generate the model. • Although the term eco geography presents in many research papers, this is the first paper that build the theory. • The study area was Sudan. It is a northeast African country at latitudes 14ºand 22º North and longitudes 22º and 38ºEast Figure (2). • Figure (3.1) depicts the research strategy. From an eco-geographical analysis of both desertification and locust infestation distribution, models and sub- models were developed to explain the interaction and interrelation between these two phenomena.
