Grain markets at national and regional level are fragmented, inefficient and subject to frequent ad-hoc government interventions in form of export/import tariff and non-tariff barriers to trade. Consequently, one part of the region may be suffering drought and hunger while another part of the same region has food rotting in the fields with producers fetching very low prices simply because regional trade in food is prohibited by national governments ostensibly for “national food security” reasons.
