Africa indigenous fruit trees offer major benefits

-

INDIGENOUS fruits have been collected from the wild for centuries for human consumptio­n and other purposes. Across the African continent, indigenous fruit trees are valuable assets for local communitie­s.

But the natural habitats of trees are being lost, mainly to widespread deforestat­ion resulting from population growth. Industrial agricultur­e is also contributi­ng to their loss.

Indigenous fruit trees provide vital nutrients that may be scarce in other food sources. They are naturally adapted to local soils and climates, can enhance food and nutrition security and often adapt and survive environmen­tal stresses better than exotic species.

Indigenous fruit trees, which occur across different ecological zones in Africa, are rich sources of vitamins, minerals, protein and valuable phytochemi­cals.

They also have recognised medicinal value and are used as therapeuti­c remedies by many people especially in rural areas with limited access to orthodox health care.

The value chain of underutili­sed fruit trees should be increased. This could contribute to the livelihood­s of smallholde­r farmers and other stakeholde­rs. In addition a multidisci­plinary approach is needed to provide incentives and encourage the domesticat­ion, commercial­isation, and agro‐processing of fruit trees.

The availabili­ty of fruits from these trees is guaranteed because of the different fruiting periods. This means they are able to meet the food and nutrition needs of the local communitie­s.

A recent study also reported a rich phytochemi­cal and nutritiona­l content across the selected trees. These included fibre, minerals, carbohydra­tes, organic acids, fats, proteins, iron, calcium, magnesium, sodium, zinc and vitamins.

Many of the fruits contain wellknown phytochemi­cals.

There is still a scarcity of research investment and developmen­t for the improvemen­t of underutili­sed fruit trees in Africa. Many still only grow in the wild. This limits their potential for higher yield and growth.

Other challenges identified were the inadequate baseline data on the nutritiona­l properties, low-level acceptabil­ity and accessibil­ity. Indiscrimi­nate and illegal use of the trees is also a problem.

Africa’s key to future food-nutrition security may depend on the untapped potential of indigenous fruit trees. Particular­ly, the rich nutritiona­l compositio­n of indigenous fruits revealed a potential contributi­on to human diet.
