Typologie Et Répartition Des Espaces Verts Publics Dans Le Grand Nokoué (Sud Bénin)

Abstract

Urban green spaces are essential to ensure the quality of life and the fulfillment of town-dwellers. The objective of this research is to assess the richness of public green spaces in the great Nokoué cities (AbomeyCalavi, Cotonou, Ouidah, Porto-Novo and Sèmè-Podji). The itinerary method was used to find the greens spaces whose list was obtained in the town halls. For each public green space found, the geo-referencing (tracking), the determination of the area of the public places and the measurement of the length of the tracks were made. The results revealed that the great Nokoué cities have 114 public green spaces which can be classified in four types (green Spaces of Tribes 4,39 %, Green Spaces of Pathways 13,16 %, Parks and Squares 26,32 % and Public Roads Alignment Trees 58,77 %). Cotonou is the city of the great Nokoué richest in public green spaces (61,95 %) whereas Ouidah has the highest ratio of public green spaces per inhabitant (Ouidah, 0.27 m2 /hbt, Porto-Novo, 0.18 m2 /hbt , Cotonou, 0.12 m2 /hbt Abomey-Calavi 0,06 m2 /hbt and Sèmè -Podji, 0,06 m2 /hbt ). No city of the great Nokoué has reached the ratio of 10 m2 of public green space per inhabitant as recommended by OMS. It is therefore important that urban authoritys give far greater attention to public green spaces (gardens, parks, squares, etc.) in future development plans.
