Through the Grande Mayumba Agriculture Company (GMAC), we are implementing one of the most promising large-scale, integrated greenfield agricultural developments worldwide.

Our concession incorporates over 200,000 ha of undeveloped grassland, of which 40,000 ha is irrigable and suitable for commercial crops with significant revenue generation potential. The key to this development is its integrated approach and supporting infrastructure, including a shallow water port located within 100 km, power, water supply, roads and municipal services.

Sugar cane

Sugar cane will be the anchor crop, with 23,000 ha zoned for its cultivation. The choice of sugar cane as the anchor crop is supported by:

Favourable agronomic and climatic conditions, including good soils, high mean annual rainfall and plentiful water supply from the Nyanga River
The value of molasses as feedstock for cattle
Potential to produce energy from bagasse & ethanol for local power provision
Suitability for mechanisation, required in this sparsely populated area
Local availability of lime, which is required to boost sugar yields
Bioethanol, produced as a bi-product, will help Gabon to reduce costly imports of refined fuels
By 2030 we expect to be producing 228 000 tonnes of sugar per year, helping to satisfy pent-up regional demand. Nigeria alone currently imports about 1.74 million tonnes of raw sugar per year from much further afield.

Cattle Ranching

A major focus is the progressive development of the existing cattle business from the 4,450 head to its full potential of 80,000 head over the coming 25 years. The meat produced will be sold into local markets only to replace imports while reducing the consumption of bushmeat.

“Since 2021, we have made huge operational improvements at Nyanga Ranch, repairing infrastructure, upskilling frontline cattle staff, improving health services, and implementing a grassland management plan that will not only improve cattle condition but also boost soil carbon levels“

— Kevin Leo-Smith, Development Director

Regional infrastructure

Development of regional infrastructure, such as roads, modular mills, a bagasse plant, lime quarry and port, to support the production of sugar cane is planned by 2025. This infrastructure will support the development of supplementary crops such as rice, maize, soybeans, avocados and citrus, optimising the commercial value of the agribusinesses and help to fulfil regional food security requirements.
