Plantwise have recently been investigating APHLIS data, a great source of information on postharvest losses in Sub-Saharan Africa. The system is run by a network of local experts who collect and supply data. Using a shared database and a Losses Calculator APHLIS provide estimates of weight losses for cereal grains at a national and provincial level.
Data is collected on crop type, farm type and climatic region and then several seasonal factors such as the duration of damp weather, harvest/market dates and storage periods are taken into account to calculate the loss estimates. Data can be viewed as tables or maps on the APHLIS website.
ALPHIS also publish pest information on the Larger Grain Borer (LGB). This particular pest attacks maize and dried cassava roots. The LGB can be very damaging compared with conventional pests of maize. If a severe attack of the pest is present, the estimated storage weight losses can double.
