Despite the Mambilla Plateau in Taraba State having favourable conditions for Arabica coffee cultivation, including a cool climate, high altitude and fertile volcanic soils, coffee remains an underutilised cash crop in Nigeria. Its production has stagnated due to smallholder farming systems, declining soil fertility, poor soil-borne disease management, and limited processing and value addition. This review examined peer-reviewed and open-access literature published between 2021 and 2026, focusing on farming systems and soil fertility, major coffee diseases, processing and value addition, and sustainable production strategies. Evidence from similar African highlands indicates that smallholders dominate production, often cultivating coffee on degraded, increasingly acidic soils with limited soil testing. Coffee berry disease, caused by Colletotrichum kahawae, can cause significant yield losses under favourable disease conditions. Unlike other African coffee-producing countries, where wet and semi-washed processing methods support higher bean quality and market value, dry processing remains dominant in Nigeria. The review recommends an integrated approach involving regular soil testing, balanced nutrient replenishment, shade-based agroforestry, disease monitoring and management, farmer cooperatives, and investment in quality-focused processing to improve the productivity, resilience and profitability of coffee production on the Mambilla Plateau.
