Nigeria is the world's leading cassava and yam producing country. Although the bulk of the production is still destined for home consumption and traditional food products such as garri, fufu, lafun, elubo, gbodo, roasted yam, boiled yam, etc. The processing for industrial end-user markets (e.g. starch, flour mills and bakery industry) has seen some promising investments during the last decade plus the Agricultural Transformation Agenda (ATA) of the current administration. Government supported initiatives have played a positive role in this respect.

Yam is one of the important crops in the farming systems of South-western Nigeria with more than 2.8 million hectares of land under cultivation annually (IITA, 2002). It contributes significantly to dietary calories per capita daily and serves as an important source of income to the people (Olaoye,and Oyewole 2012). Yam production in Nigeria is concentrated mostly in all the southern and central states. Major yam producing states in south west Nigeria include Ondo, Ekiti and Oyo states, while the major urban marketing outlets are found mostly in Lagos and Ibadan.

Our partners in Nigeria are the Federal University of Agriculture, Abeokuta (FUNAAB), Federal Institute of Industrial Research, Oshodi (FIIRO), Peak Precision Products Ltd and Nobex technical company Ltd.

nigerianstudentBeing part of this world, I have experienced the devastating impact of discarded waste generated from various industrial and agricultural processes when this waste actually has a high potential to be recycled and converted into high value products.

As a food scientist, reducing postharvest losses is a continuous challenge, so it is a fantastic opportunity to be involved in the Gratitude project whose goal is to address this issue.

I am honoured to be part of this project, it has given me the confidence to communicate to individuals that instead of disposing and burning cassava peels, farmers can grow mushrooms, a highly nutritious fungus that has the potential to contribute to solving the problem of protein malnutrition, unemployment and food insecurity.

Inputs from experienced researchers also involved in the Gratitude project have guided my research in extending the shelf life of mushrooms grown on cassava peels to 24 days; 22 days longer than the usual 2 day period.

Through the project I have had the opportunity to see the commercial production of mushrooms using cassava and yam wastes as substrates, as a great means of income generation. I am now planning to attend intensive training on mushroom production in order to start my own mushroom farm.

Mushroom production process in Ghana

Mushrooms are grown from a growth material called 'substrate'. To create the substrate, cassava or yam peels are dried and then milled. Water, lime and rice bran, are added, and the substrate is mixed and heaped into a pile on the ground. It is then left to ferment for 28 days. The compost needs to be turned every 4 days for proper aeration and uniform composting.
