A. G. Hopkins has observed that where new plants and seeds were adopted it was because they were seen as useful additions to the existing range of foods, or because they were regarded as good substitutes to the crops they displaced. This view is confirmed by a close study of the changing food patterns on the Lower Niger since 1520. Prior to 1919, cassava was hardly cultivated on the Lower Niger even though it was widely grown in the neighbouring Niger Delta. This was essentially because the people of the Lower Niger did not consider cassava as a good substitute for yams. However, after 1900 the Lower Niger became the scene of wars of resistance against the imposition of British rule. These wars not only resulted in a constant disruption of the agricultural activities of the local people, they also caused food shortages. The situation was worsened by the First World War and by the pandemic of influenza of 1918–19 which drained the nation's productive capacity and caused an unprecedented food scarcity. Under the circumstances, the people of the Lower Niger were constrained to accept cassava, at least as a supplement to the dwindling stocks of food. And as soon as it was realized that the new crop enjoyed a number of advantages over yams, its cultivation rapidly spread to all parts of the Lower Niger where it began to threaten the older staples. The speed with which this innovation was adapted clearly points to the degree of the food crisis that accompanied the pandemic influenza of 1918–19.
3 One version of the Nri traditions claims that God sent Eze Nri with yams to feed the Igbo peoples.
