"Africans have a rich cultural heritage and a wealth of traditional knowledge on topics ranging from agriculture and forestry to medicines and medical practices ... Much of this type of knowledge is embedded in the diverse local languages and cultures found in Africa. Yet despite centuries of scientific undertakings on the continent, there is still no vernacular word for 'science' ... [Science] remains a minority, English-language based pursuit ... at the expense of local languages." (Quoted from article)
