Overview of the institutions actively engaged in coconut research 

Ghana's coconut R&D integrates public research institutes (CSIR-OPRI disease resistance leadership), regulatory authorities (TCDA value chain coordination), universities (KNUST and UG waste valorization focus), farmer associations (COFAG/CoSNAG representing community interests), and innovative private sector (Melach pioneer export-oriented processing). This framework supports Ghana's transformation toward USD 700M+ coconut export industry by 2030 through sustained collaboration between national and international partners (CIRAD, Bioversity International, World Bank, AFD, EU) while managing endemic Cape St Paul Wilt Disease.

  • CSIR-Oil Palm Research Institute (CSIR-OPRI) - Coconut Research Programme: Established 1964, operates Sekondi-Takoradi Western Region outstation; primary mandate for sustainable coconut research including Cape St Paul Wilt Disease resistance breeding, variety screening (MYD x VTT hybrid, SGD x VTT), diagnostic assays development, and integrated pest management; collaborates with CIRAD, Bioversity International, EU TropicSafe Project, and AFD-funded CSDP (1999-2005).
  • Tree Crops Development Authority (TCDA): Established 2019 (officially inaugurated 2020); headquarters Kumasi; regulates and develops sustainable production of six tree crops including coconut; implementing Ghana Tree Crop Diversification Project (P180060, 2024-2029, USD 200M World Bank); projected revenue target USD 2 billion annually in coconut exports through technical advice, capacity building, nursery protocols, and value chain diversification.

  • 1815 - Coconuts were introduced to West Africa, including the Gold Coast (Ghana), by Portuguese colonial seafarers in the 16th century via Cape Verde Islands (Portuguese introduced coconuts there in 1499), which supplied the Atlantic coasts and West African coast; Dutch sources mention coconut cultivation at Elmina as early as 1815 in a Dutch book published that year, suggesting coconuts were present at this major Portuguese (1482-1637) then Dutch (1637-1872) trading post.
Field mission carried out in 2000 and related publications

A mission was conducted by R. Bourdeix in January 2000 to study seednut production and the breeding aspects of the project “Coconut Sector Development Project in Ghana.” This new project is implemented under the supervision of the Ghana Ministry of Food and Agriculture (MOFA). Its budget amounts to about 34 million French Francs, of which 77 % is financed by the French Government (through the Agence Française de Coopération), 12 % by Ghanaian farmers, 9 % by the European Union, and 2 % by the Government of Ghana. Ghanaian coconut plantations cover approximately 40,000 hectares, distributed within the Central Region (10 %) and the Western Region (90 %). The Cape St. Paul lethal yellowing disease has so far destroyed at least 4,000 hectares. Ghana Rubber Estates Limited (GREL), a private Ghanaian company, was chosen to lead the project. Frédéric Lefebvre serves as project manager. The applied research programme is being carried out jointly by OPRI (Oil Palm Research Institute of Ghana) and the Coconut Research Program of CIRAD, France.

The three main components of the project are as follows: 1) Intensification of 2,000 hectares of existing coconut plantations, where an increase of 40 to 50 fruits per palm per year is expected. 2) The improvement of small-scale coconut oil processing. 3) The replanting of 1,200 hectares with coconut cultivars tolerant to the disease.

The Aiyinasii Seed Garden produces the hybrid between Malayan Yellow Dwarf (MYD) and Vanuatu Tall (VTT). Later, the hybrid between Sri Lanka Green Dwarf (PGD) and VTT will also be produced in Ghana, as PGD has shown better tolerance to the disease than MYD in this country. The choice of the site for a new seed garden, including MYD, SGD, and VTT cultivars, was discussed. At the Aiyinasii Seed Garden, seednut production in 1999 was low, and the illegitimacy rate was quite high. However, the production estimate for the year 2000 is much more optimistic: about 150,000 seednuts are expected, which is sufficient to reach the annual target of the project. This corresponds to 89 seednuts per palm within a six-month production period—better than the standard. The nursery visit showed that the illegitimacy rate had been over-estimated. Recommendations were made to improve seed production techniques.

A solution was proposed to use the 16 VTT palms remaining in the disease-resistance trials. These palms can be used to produce some VTT pollen and seednuts locally. At the same time, they can serve to establish a new and promising breeding experiment at low cost (as it will be located within the seed garden). This experiment will be a full diallel design involving eight VTT palms. The assistance of the Côte d’Ivoire International Germplasm Bank will again be required to provide VTT pollen and seednuts, and also to extend the range of cultivars tested for disease resistance.

Observations importantes réalisées au Comores par R. Bourdeix

Des observations de zones particulières plantées de cocotiers et soumises à une forte érosion ont contribué au développement des projets CocoEro: "Utilisation de systèmes agroforestiers à base de cocotiers pour lutter contre l’érosion côtière sur sols sableux".

Données historiques sur les variétés de cocotier et les mouvements de matériel végétal impliquant les Comores.


Le document IRHO de Delorme (1973) "Le cocotier dans l'archipel des Comores" confirme que:​
  • L'introduction du cocotier aux Comores est "fort ancienne", remontant vraisemblablement aux premières incursions des boutres arabes"​
  • La variété traditionnelle "Grand Comorien" était dominante dans l'archipel​
  • Dans les années 1970, le coprah était le 4ème produit d'exportation (~4,000 tonnes/an)​
  • Surface totale: ~50,000 ha répartis sur Grande Comore (16,500 ha), Anjouan (7,500 ha), Mohéli (6,000 ha)​
Dans les années 1960-1970, l'IRHO a introduit du matériel génétique exotique incluant:
  1. Nain Jaune Malaisie (NJM)​
  2. Nain Rouge Cameroun (NRC)​
  3. Grand Ouest Africain (GOA) - variété ouest-africaine​
A cette occasion, la variété "Grand des Comores Moheli" a été introduite en Côte d'Ivoire, dans la collection de l'actuelle Station CNRA Marc Delorme. Dans les années 1980: Le projet Banque Mondiale a planté des hybrides PB121 (Nain Jaune Malaisie x Grand Ouest Africain) et PB111 (Nain Rouge Cameroun x Grand Ouest Africain) à partir du  champ semencier de Bouanifoungue à Mohéli​

Aucun document ne détaille les programmes de replantation immédiatement après le grand Cyclone de 1898. On peut émettre des hypothèses sur les plantations post-1898, étant donné:
  • La dévastation complète des plantations en 1898​
  • La proximité avec Madagascar (sous contrôle français depuis 1896) où des stations agricoles coloniales étaient actives​
  • Les relations commerciales avec Zanzibar (centre majeur de production de coprah)​
  • La présence de la variété "Grand Comorien" traditionnelle qui aurait dû être réintroduite
Il est très probable que les autorités coloniales françaises aient organisé des introductions de semences de cocotier depuis:
  • Madagascar (Station d'Ivoloina près de Tamatave, créée en 1897)​
  • Zanzibar (grand producteur régional de coprah)​
  • Seychelles (autre colonie française de l'océan Indien)
  • ou Éventuellement Maurice ou La Réunion
Cependant, aucun document spécifique décrivant un programme formel de replantation post-1898 n'a été identifié dans les archives Gallica ou CIRAD consultées. Cette lacune documentaire pourrait s'expliquer par la perte d'archives coloniales, le caractère informel des replantations (initiatives privées des planteurs), la priorité donnée à d'autres cultures (ylang-ylang, vanille, girofle) dans les années 1900-1920​.

Pour continuer une recherche approfondie et confirmer cette hypothèse, il faudrait consulter:
  • Archives Nationales d'Outre-Mer (ANOM) à Aix-en-Provence
  • Journaux Officiels de Madagascar et Dépendances (JOMD) 1898-1920 sur Gallica
  • Bulletin économique de Madagascar (années 1900-1920)
  • Archives de l'IRHO (prédécesseur du CIRAD) concernant les prospections génétiques historiques.
Cette recherche historique révèle un vide documentaire significatif sur la période critique 1898-1950 pour le cocotier aux Comores et à Mayotte, période pourtant cruciale pour comprendre l'origine des variétés actuelles.
