Biodiversity conservation is a key factor in meeting sustainable development goals. This is even more important in cities, where green spaces are becoming increasingly scarce. This study analyzes Kinshasa’s proliferating ornamental plant nurseries, known as informal horticultural sites (IHSs). The analysis focused on characterizing the profile of horticulturists, their production conditions, and the ornamental species produced. A total of 15 IHSs were sampled using the “snowball” technique, and 178 horticulturists were surveyed. Based on the socio-professional profile of the horticulturists, five groups of IHS are distinguished after a hierarchical clustering of principal components (HCPC). We found that IHSs exclusively employed men, most of whom were new to the trade, from all levels of education, and most of whom ranged from 19 to 45 years old. Production conditions are relatively similar from one site to another. However, all IHSs are characterized by permanent land insecurity, the use of phytosanitary products, plant-conditioning methods that are not very diversified and calibrated to growers’ investment capacities, and diversified seed acquisition methods. A total of 139 ornamental species, most of them exotic, were identified. Of these, 37% are phanerophytes, and 24% are considered potentially invasive. We suggest ways of professionalizing the activity and protecting the urban environment.

“…For example, A. niger is not responsible for as many human diseases as other species of Aspergillus, but at high concentrations, it can cause aspergillosis, which causes lung abnormalities, a disease that appears more frequently in horticulturists. 204 Some spores can induce a human pathogenicity, because of their allergenic properties; for instance, the spores of Alternaria are allergenic and can induce an allergic response at a concentration to 100 spores in one cubic meter of air; for Cladosporium the concentration is 3000 spores per cubic meter. In general, conidia up to 5 μm in diameter are responsible for type 1 allergies, because they remain in the upper parts of the aerial tract (nostrils, sinuses, bronchial tubes).…”
