An international NGO is warning that production of local kinds of crops and breeds of animals is severely threatened in Africa. Slow Food International is based in Rome. It’s fighting a global battle to save local food traditions. The organization says local food usually isn’t produced with the help of harmful chemical pesticides and antibiotics. The same cannot be said non-indigenous crops and animals that aren’t adapted to African conditions. According to Slow Food, this makes traditional food far healthier. But, it says, the availability of such these foods is steadily declining. In the fourth part of a series on African agricultural initiatives, Darren Taylor reports on efforts to revive local African foods.
