Summary for Project title: R5104: Investigations on stackburn in sub-Saharan Africa.

Improved techniques for long-term storage are opening up new opportunities in developing countries. Large-scale storage is essential for grain marketing chains and food security systems, yet over time, quality deterioration often leads to nutritional and financial losses. Now maize stackburn, resulting from the build-up of heat in the interior of bag stacks, can be avoided by using passive ventilation. For milled rice in hot humid climates, quality is ensured over several years by sealing bag stacks into plastic envelopes flushed with phosphine or carbon dioxide. This long-term rice storage technique is used in Indonesia, the Philippines and Vietnam, to safeguard these nations' emergency rice reserves.
