Gorongosa coffee is exported around the world, with profits ploughed back into the plantation.
The forest's revival reflects Gorongosa's larger rebirth, since a 20-year partnership was formed in 2008 between Mozambique and the foundation of American philanthropist Greg Carr.
The World Bank has praised the partnership as a model, which has benefited some 200,000 people in the area.
The programme also aligns with the government's goal of improving agriculture and moving beyond exports of raw commodities, said Celso Correia, Agriculture and Rural Development minister.
"One of the biggest challenges in the agriculture sector is the lack of mechanisation, and the need for technology transfers," he said.
"The priority is to mobilise resources, but also to improve mobility, developing infrastructure and transportation, so that we can improve the value chain."
