Nigeria’s Dangote Group, which is controlled by Aliko Dangote, Africa’s richest man, revealed earlier this month that it plans to invest more than $4-billion in agriculture over the coming three years. Bloomberg reports that the company plans to increase its production of sugar to 1.5-million tons a year by 2020, up from 100 000 t currently, and add a million tons of rice to its portfolio. In addition, Dangote plans to have 50 000 cattle producing 500-million litres of milk a year by 2019.
