Essai de géographie systématique : les paysages du Nord-Ouest de la Côte d'Ivoire

Abstract : This thesis study analyses geographic space giving scope to rain and rivers, rock formations and relief, vegetation, ground surface and soil...However one shouldn't be surprised to find that fallow land, villages and orchards are included in the study.
It has the ambition of participating in the development of geographic study centered on the organization of materiel space formed by the actions of nature and society.
The author emphasises the importance of one essential aspect which is the study of dimensional change in scalar analysis.
The Abidjan analytic method for biophysical environments and land systems co-founded by Jean Charles Filleron is the method used. Thirty months of on site study were necessary to produce 826 descriptive summaries of the vegetation, ground surface, and soil. More than 2500 aerial photos were analysed in view of both landform and land cover data.
Treatment of multivariable statistics, ACP, AFC and their classification paved the way for a systematic survey of biophysical environments and land systems in different scalar gradations.
The study site is the NW of the Ivory Coast, a vast region of 49000 square kms, the majority of which is more or less wooded savannas which cover ferricrete plateaus and inselberge. In this sparsely populated region the author demonstrates the role of rural societies...and the nature of rock substrata... in the bio- and geodiversity pattern, with innovative discourse on the subject of ecology in tropical areas.
