In Zimbabwe and other parts of sub-Saharan Africa, farmers use grain stores constructed from grass, stalks of cereal crops and wooden poles. Some of these constituent parts are increasingly scarce. Mud plastered stores, supported on concrete-filled plastic pipes, offer the benefits of improved resistance to termites, insect grain pests and rodents. Environmental sustainability would be improved though reduction in use of scarce wood construction materials, although the stores would not be sufficiently gas tight to allow fumigation.
