In Lagos alone,lagosians pays about 8 billion naira per day for food according to Lagos state government, this is different from other cities and countries in Africa.

The agric sector has a long chain from the food produced by the farmer to the table of the consumer.

From my experience, not all agribusiness are profitable (depending on circumstances which I will explain later).

To cut the long story short, these 3 agribusiness are profitable and if you want to venture or invest into it, it's the way to go.

NOTE: All agribusiness mentioned here are some of the ones I have been involved in and make profit from.
