The research activities of this Coordination are aimed at (i) the sustainable management of resources, the conservation of the environment in general and biodiversity in particular, (ii) the constitution of collections for research and (iii) the exploitation of results by providing users with technological data that meets their needs. As a reference structure for institutional forestry and environmental research, it also ensures the collection, processing and dissemination of scientific and technological information, and maintains scientific cooperation relations
with specialized national and international institutions.

Objective

  • Enable the forest to perform its economic, ecological and social
    functions while preserving the interest of all stakeholders;
  • Allowing soil resources to be managed for the preservation of their potential for agricultural production

Research Programs

Forest and Wood Program

The decline in timber potential is detrimental to the balance between needs and resources. Besides, the reduction of vegetation cover affects climate, water regimes, soils and the supply of wood energy. This is related to the combined effects of uncontrolled logging and agricultural clearing, grazing and drought. This program aims to develop methods and strategies for sustainable management and rational use of forest resources.

Soils, Water and Atmosphere Program

This Research Program aims to contribute to the control of chemical and physical degradation factors on soils, water and the atmosphere, in order
to know and better control their beneficial potentials. It also contributes to the preservation of ecological balances through the production of
mitigation and adaptation tools to climate change

Biodiversity Program

The aim of this program is to conduct inventory and determine Cameroon’s flora and fauna diversity and preserve their genetic diversity for conservation management.

Salient results

Timber production:

  • Mastery of silvicultural techniques of local and introduced (exotic) species;
  • About sixty local species and ten exotic species have been introduced into the Sudano-Sahelian zone;
  • Five local species and a dozen exotic species have been introduced in the wet savanna zone, as well as the main timber species of the Congo-Guinean floristic region (Southern Cameroon forest);
  • Mastery of silvicultural techniques of pine and eucalyptus in humid savanna zone;
  • Knowledge of the technological potential of 26 forest species;
    Development of reduced impact logging techniques including inventories, mapping, directional logging, and skidding by the shortest runway;
  • Development of restoration techniques, recolonisation and valorization of hardened soils.

Non-wood forest products:

  • Development of low-cost cutting techniques of Gnetum africana;
  • Development of a conservation method for pre-germinated cuttings of Gnetum.

Conservatory soil management:

  • Production of easy-to-use soil information to identify the different soil types and their fertility potential;
  • Demonstration of the presence of pathogenic bacteria and many polluting elements at concentrations higher than internationally accepted standards in the waters of the lowlands of Yaounde. The isolated bacteria are: Proteus vulgaris, Enterobacter cloacae, Escherichia coli, Proteus vulgaris, Klebsiella pneumoniae, Pseudomonas sp. These results are indicative of the precautions to be taken in the management of lowlands, especially in relation to the exploitation of these areas for peri-urban agriculture.
  • Development of analytical techniques for assessing the dynamics of organic carbon, nitrogen and phosphorus and quantification of carbon sequestration in acrisols and ferralsols;
  • Documentation of nitrogen fixation and mobilisation of organic matter, water and phosphorus in Acrisols / Ferralsols as well as knowledge of the critical thresholds for crop response of these parameters;
  • Characterization of soils in forest areas and their fertility status with particular reference to organic matter, water, nitrogen and phosphorus.

Climate Change and Biodiversity:

  • Establishment of the “Letouzey” basic collection, containing data for over 40,000 herbarium specimens;
  • Systematic reviews of 5 genera including Dacryodes, Santiria, Bertiera and Sherbounia;
  • Publication of four checklists for the Conservation of Forest Reserves of Mount Cameroon, Bali Ngemba and Mount Oku, the Bakossi Mountains National Park, the Kupé and Manengouba Ecological Reserves with information on forest fauna;
  • Identification of 400 threatened plants of Cameroon (IUCN Red List available online);
    Molecular characterization of specimens of Rinorea (Violaceae) and description of many plant species collected in Cameroon including: Afrothismia hydra (Burmaniaceae), Psydrax bridsoniana (Rubiaceae), Manilkara lososiana (Sapotaceae) and Hypolytrum pseudomapanioides (Cyperaceae);
  • Knowledge of the mycorrhizae diversity of more than 300 species and plants grown in Cameroon’s rainforests.

Ongoing Projects

Perspectives

  • Capacity building of junior scientists and rural development stakeholders
