Urban forest and sustainability: the historical perspective of Limbe in the Southwest Region of Cameroon

Abstract

Projected rapid urbanisation and climate change will increase the risk of natural disasters in fragile coastal African cities. Strategically planning and managing the urban forest can help to build resilience. This study aimed to document urban forest development and sustainability in Cameroon using the city of Limbe as a baseline through the classification of urban forest elements; description of their developmental history and assessment of the level of sustainability to inform strategic planning. Data was collected using a forest ethnology approach. Two groups of stakeholders’ representatives of public institutions (Group 1), Non-Governmental Organisations and educated indigenes (Group 2) provided oral histories of tree planting. Face to face interviews with 15 stakeholders were conducted guided by semi-structured questionnaires. From these results, there are four types of urban forest. Limbe Botanical Garden (LBG) developed during the colonial era was the most prominent. Municipal authorities by law should create different types of urban forest but their actions have been limited to Roadside Trees (RT) planting. The absence of budget, policy and inventory was responsible for the low level of urban forest sustainability. Increasing awareness of the effectiveness of urban forest nature-based solutions in tackling deadly landslides and floods in Limbe can promote urban forest sustainability.
