The African Postharvest Losses Information System (APHLIS) is the foremost international effort to collect, analyze and disseminate data on postharvest losses of cereal grains in sub-Saharan Africa. In its latest phase, known as APHLIS+, the service is expanding the range of crops it covers to include legumes and roots and tubers. APHLIS+ includes estimates of the economic and nutritional dimensions of postharvest loss. APHLIS+ will also improve the interactive tools for accessing loss data and will expand its network of African experts.

How APHLIS estimates loss

APHLIS provides evidence-based data on postharvest loss at a large scale that would be prohibitively expensive to obtain by direct observation. It does this by combining loss data from academic research with contextual observations from local experts.
