Analysis of Anthropogenic Disturbances of Green Spaces along an Urban-Rural Gradient of the City of Bujumbura (Burundi)

Bujumbura city has diversified but unevenly distributed green spaces. The typology and anthropogenic disturbances of these green spaces are still unknown. This study presents a typology of green spaces along the urban-rural gradient through a literature review. It assesses the presence of anthropogenic disturbances through inventories in 100 m x 100 m grids. Data reveal that Bujumbura's green spaces are made up of green squares concentrated exclusively in urban areas, cemeteries present in peri-urban areas and sports green spaces observable all along the urbanization gradient. These green spaces are more exposed to trampling, which is more present in administrative entities with a peri-urban morphological status, as opposed to various constructions in administrative entities with an urban status. Finally, significative pairwise associations of anthropogenic disturbances were observed. The results show the need to protect these green spaces from all kinds of anthropogenic disturbances by raising the eco-responsible awareness of the population and the municipal authorities.
