One problem, three perspectives: data, people, policy. Every figure with its source.

The scale

Losses of fruit, vegetables and tubers are far higher than those of grain. That is exactly where our drying comes in.

44 %

of the mango harvest in sub-Saharan Africa is lost along the chain (median of 7 studies).

Women carry agriculture, yet have less land, lower pay and less training. That is why Femmepact exists.
