The industrialised world’s plant biotechnology portfolio is based on a limited number of large commodity crops and input traits, and in general is unavailable and unaffordable, if not unsuitable, to the needs of sub-Saharan Africa (SSA) where per capita agricultural production has decreased since the 1960s. Governments and organisations involved in providing technological help must take into account the conditions under which small-scale — often subsistence — farmers of a particular region work. It is suggested that in order to be sustainable, biotechnology for SSA should in the first instance be tissue culture-, molecular marker- and biocontrol-based, as well as stongly orientated toward regional crop diversity. However, many of the constr...
