In urban areas, trees remain the essential element in maintaining the environmental balance. Specifically, this study aimed to: (i) quantify the loss of urban tree cover and deepen knowledge of the drivers of this urban deforestation; (ii) understand the influence of the loss on the local climate; and (iii) clarify the management methods of this urban ecosystem guaranteeing environmental resilience. The results of analyzes showed that in Kinshasa, trees are cut even in the inhabited plots in order to supply the pastry companies and nganda ntaba with firewood. Between 2000 and 2020, nearly 25% of the initial tree area was deforested; the average annual loss of tree cover in the urban and peri-urban area is estimated at approximately 1128.8 ± 910.9 ha. The average daily quantity consumed by an artisanal bakery and a nganda ntaba amounts respectively to 3.36±1.25 m3 and 2±0.67 bundles of firewood. The results of the analyzes demonstrated the influence of urban tree cover loss in Kinshasa on the increase in local temperature. The restructuration of Kinshasa city, the promotion of renewable energy and urban forestry, would make Kinshasa a resilient city.

The results of analyzes showed that in Kinshasa, trees are cut even in the inhabited plots in order to supply the pastry companies and nganda ntaba with firewood. Between 2000 and 2020, nearly 25% of the initial tree area was deforested; the average annual loss of tree cover in the urban and peri-urban area is estimated at approximately 1128.8 ± 910.9 ha.

Abstract: (french)
En milieu urbain, l’arbre reste l’élément incontournable dans le maintien de l’équilibre environnemental. Spécifiquement cette étude visait à: (i) quantifier la perte du couvert arboré urbain et périurbain et approfondir la connaissance des moteurs de la perte du couvert végétal dans le milieu urbain; (ii) comprendre l’influence de la perte sur le climat local; et (iii) clarifier les modes de gestion de cet écosystème urbain pouvant garantir une résilience environnementale. Les résultats des analyses ont montré qu’à Kinshasa les arbres sont coupés même dans les parcelles habitées afin d’alimenter les entreprises pâtissières et nganda ntaba en bois de chauffe. Entre les années 2000 et 2020 près de 25% de la superficie arborée initiale ont été déboisés; la perte annuelle moyenne du couvert arboré dans la zone urbaine et périurbaine est évaluée à environ 1128,8 ± 910,9 ha. La quantité journalière moyenne consommée par une boulangerie artisanale et un nganda ntaba s’élève respectivement à 3,36±1,25 m3 et 2±0,67 fagots de bois de chauffe. Les résultats des analyses ont démontré l’influence de la perte du couvert arboré urbain de Kinshasa sur l’augmentation la température locale. Le réaménagement de la ville de Kinshasa, la promotion de l’énergie renouvelable et de la foresterie urbaine, feraient de Kinshasa une ville résiliente.
