Available for over a year

Among the solutions suggested is switching to homegrown alternatives, like cassava flour in place of wheat. But according to Victor Otieno from management consultancy Viffa Consult, such policies would require a 'systemic change' in production chains. (Photo: A woman makes cassava flour.
